Introduction: Acute pulmonary edema (APE) due to fluid overload is considered the most feared complication in hemodialysis patients. Various diagnostic tests have been proposed to assess the fluid status in patients with end-stage kidney failure (ESKF); among these, lung ultrasound (measuring the number of B-lines) is emerging as a promising tool to identify pulmonary congestion in this patient population. Methods: We compared the incidence of APE before and after the implementation of lung ultrasound as a routine practice in our unit. The pre (from 1 January 2007 to 31 December 2008)- and post (from 1 January 2017 to 31 December 2018)-B-line implementation periods included 98 and 108 hemodialysis patients, respectively. By accurately reviewing their electronic medical records, all episodes of APE were collected. The 10-year interval between the two periods was specifically chosen to ensure no overlap between patients of the two cohorts whereas the single-center design was adopted to minimize the influence of center effect on the study results. Results: APE episodes occurred more frequently in patients from the pre-B-line implementation group (18/98, i.e., 18.4%) compared with those from the post B-line implementation group (6/108, i.e., 5.5%) (p = 0.004). An analysis based on repeated APE events showed that the incidence rate of APE was significantly higher during the pre-implementation period (2.0 APE episodes per 100 person-months, 95% CI: 1.4–2.7) than during the post-implementation period (0.3 APE episodes per 100 person-months, 95% CI: 0.1–0.7), with an incidence rate ratio (post- versus pre-) of 0.17 (95% CI: 0.07–0.40; p < 0.001). The odds of experiencing APE episodes were 74% lower (odds ratio: 0.26, 95% CI: 0.10–0.69) in patients from the post B-line implementation period compared with those from the pre-implementation period. Notably, adjusting for potential confounders did not affect the strength of this association, which remained statistically significant (p ≤ 0.030). Finally, dominance analysis indicated that the implementation of B-lines was the primary factor explaining the difference in APE episodes between the two periods, followed by dialysis duration and intra-dialysis weight gain. Conclusions: The systematic use of lung ultrasound (a simple, easy-to-learn, rapid and non-invasive method, easily performed at the patient's bed) in everyday clinical practice was associated with a drastic reduction in episodes of APE in hemodialysis patients. Further observational and interventional studies are needed to confirm these results. [ABSTRACT FROM AUTHOR]

This pilot study aimed to evaluate the efficacy of the 4-h mean lactate clearance (LACclr) level as a predictive factor for in-hospital outcomes, 30-day mortality, and treatment success in patients with acute cardiogenic pulmonary edema (ACPE), a significant clinical form of acute heart failure (AHF).

Hypoxia, centralization of blood in pulmonary vessels, and increased cardiac output during physical exertion are the pathogenetic pathways of acute pulmonary edema observed during exposure to extraordinary environments. This study aimed to evaluate the effects of breath-hold diving at altitude, which exposes simultaneously to several of the stimuli mentioned above. To this aim, 11 healthy male experienced divers (age 18-52y) were evaluated (by Doppler echocardiography, lung echography to evaluate ultrasound lung B-lines (BL), hemoglobin saturation, arterial blood pressure, fractional NO (Nitrous Oxide) exhalation in basal condition (altitude 300m asl), at altitude (2507m asl) and after breath-hold diving at altitude. A significant increase in E/e' ratio (a Doppler-echocardiographic index of left atrial pressure) was observed at altitude, with no further change after the diving session. The number of BL significantly increased after diving at altitude as compared to basal conditions. Finally, fractional exhaled nitrous oxide was significantly reduced by altitude; no further change was observed after diving. Our results suggest that exposure to hypoxia may increase left ventricular filling pressure and, in turn, pulmonary capillary pressure. Breath-hold diving at altitude may contribute to interstitial edema (as evaluated by BL score), possibly because of physical efforts made during a diving session. The reduction of exhaled nitrous oxide at altitude confirms previous reports of nitrous oxide reduction after repeated exposure to hypoxic stimuli. This finding should be further investigated since reduced nitrous oxide production in hypoxic conditions has been reported in subjects prone to high-altitude pulmonary edema. [ABSTRACT FROM AUTHOR]

Background: Heart failure with reduced ejection fraction (HFrEF) poses significant health risks. Midodrine for maintaining blood pressure in HFrEF, requires further safety investigation. This study explores midodrine’s safety in HFrEF through extensive matched analysis. Methods: Patients with HFrEF (LVEF <50%) without malignancy, non-dialysis dependence, or non-orthostatic hypotension, were enrolled between 28 August 2013, and 27 August 2023. Propensity score matching (PSM) created 1:1 matched groups. Outcomes included mortality, stage 4 and 5 chronic kidney disease (CKD), emergency room (ER) visits, intensive care unit (ICU) admissions, hospitalizations, and respiratory failure. Hazard ratios (HR) with 95% confidence intervals (95% CI) were calculated for each outcome, and Kaplan-Meier survival analysis was performed. Subgroup analyses were conducted based on gender, age (20-<65 vs. ≥65), medication refill frequency, and baseline LVEF. Results: After 1:1 PSM, 5813 cases were included in each group. The midodrine group had higher risks of respiratory failure (HR: 1.16, 95% CI: 1.08–1.25), ICU admissions (HR: 1.14, 95% CI: 1.06–1.23), hospitalizations (HR: 1.21, 95% CI: 1.12–1.31), and mortality (HR: 1.090, 95% CI: 1.01–1.17). Interestingly, midodrine use reduced ER visits (HR: 0.77, 95% CI: 0.71–0.83). Similar patterns of lower ER visit risk and higher risks for ICU admissions, respiratory failure, and overall hospitalizations were observed in most subgroups. Conclusion: In this large-scale study, midodrine use was associated with reduced ER visits but increased risks of respiratory failure, prolonged ICU stays, higher hospitalizations, and elevated mortality in HFrEF patients. Further research is needed to clarify midodrine’s role in hemodynamic support and strengthen existing evidence. [ABSTRACT FROM AUTHOR]

Abstract Background Intravenous nitrates are a primary therapy for hypertensive congestive heart failure (CHF) with acute pulmonary edema (APE) in the hospital setting. Historically, sublingual nitrates are the mainstay of emergency medical services (EMS) pharmacologic therapy for these patients. We aimed to evaluate the safety of prehospital bolus dose intravenous nitroglycerin in patients with APE. Methods This is a retrospective evaluation of EMS data between March 15, 2018, and March 15, 2022, where CHF with APE was suspected and bolus‐dose intravenous nitroglycerin was administered. Protocol inclusion criteria were hypertension (systolic blood pressure [SBP] >160 mmHg) and acute respiratory distress, with a presumption of decompensated CHF with APE. These patients received 1 mg intravenous nitroglycerin, with the option to repeat once for ongoing distress if the SBP remained >160 mmHg. The primary outcomes were adverse events, defined as hypotension (SBP

Introduction: Chlorine gas inhalation is a toxic respiratory irritant associated with high lung complications. Despite its wide industrial and domestic applications such as bleaching detergents, there is no specific treatment for chlorine gas poisoning yet and common standard treatments are mostly supportive. In this regard, this study aimed to find a new treatment for this pathogenesis from the perspective of Persian medicine (PM). Materials and methods: In this review study, at first, we searched the etiologies and clinical symptoms associated with chlorine gas poisoning in modern medicine and then compared them with similar etiologies and symptoms in valuable Persian medical manuscripts. Then we reviewed the proposed treatments for similar illnesses from the point of view of PM. Results: The pathology of lung damage caused by inhalation of chlorine gas is reactive airway dysfunction syndrome (RADS), which leads to dyspnea, hypoxemia, respiratory tract obstruction, pneumonia, pulmonary edema, and finally acute respiratory distress syndrome (ARDS). In a comparative study, it seems that this pathology has the closest similarity with the Persian term“Varme-e-harr riye”. The treatment strategy for this syndrome in PM is bloodletting at the first and then the application of cold-temperament foods and medications to improve the lungs. Conclusion: According to the compatibility of acute pulmonary edema caused by chlorine inhalation and “varam-e-harr riye” in PM, it seems that wet cupping can be considered as a suggested primary and emergency treatment for this pathology in future clinical studies.

Neurogenic pulmonary edema (NPO) is a rare and underdiagnosed clinical entity, occurring within minutes to hours of central nervous system damage. The pathogenesis of NPO is not completely understood, systemic vasoconstriction, as a consequence of higher levels of catecholamines, associated to systemic inflammatory response lead to increase capillary permeability and result in pulmonary edema. Hypoxemic respiratory failure following a catastrophic neurological event, which cannot be attributed to other causes is the main characteristic of NPO. Management is essentially based on the control of the triggering neurologic condition in order to quell the sympathetic discharge. We report the case of female who presented hypoxemic respiratory distress following a subarachnoid hemorrhage. Clinical examination and radiological investigations led to the diagnosis of neurogenic pulmonary edema. [ABSTRACT FROM AUTHOR]

Recombinant tissue plasminogen activator (r-tPA) is the first-line drug for the treatment of acute ischemic stroke, despite it may lead to a variety of complications in some cases. In patients with extensive stroke, infarction of the brain can cause suppression of the respiratory center in the brain leading to neurogenic pulmonary edema that potentially causes respiratory failure. Its etiology is either due to a neurogenic or non-neurogenic process. Nevertheless, the definite pathophysiology of these circumstances remains unclear. In this study, we reported four cases of post-thrombolytic ischemic stroke patients who suffer from pulmonary edema with different symptoms and onset times as well as we discuss the possible explanation behind these different outcomes.

Background: Atosiban is commonly used to delay premature labor in pregnant women and is thought to have few side effects. Objectives: To report a case of acute pulmonary edema (APE) following administration of atosiban and conduct a systematic review to identify common characteristics and risk factors of atosiban-associated APE. Methods: Searches were performed in Pubmed, Embase, and Web of Science using the keyword “Atosiban” combined with the terms “Pulmonary edema” or “Dyspnea” or “Hypoxia” on 9th July 2022. Only case reports of atosiban-associated APE were included without language restrictions. Data were extracted from the reports, and median, range, and percentages were calculated as applicable. The risk of bias was assessed using the Joanna Briggs Institute critical appraisal checklist for case reports. Results: Seven cases of atosiban-associated APE were included in the systematic review, including our case. APE occurred at a median gestational age of 32 + 6 weeks. Most patients were nulliparous (6/7, 85.7%) and were in multiple pregnancies (5/7, 71.4%). All patients were prescribed antenatal corticosteroids and tocolytics, with three (42.9%) receiving only atosiban and four (57.1%) receiving atosiban and other tocolytics. The median interval from starting atosiban administration to APE onset was about 40 h, and three patients (42.9%) showed symptoms 2–10 h after the end of atosiban treatment. Radiographic examinations (chest X-ray and/or computer tomography scan) confirmed APE in all patients and pleural effusion in four patients (57.1%). Five patients (71.4%) underwent emergency cesarean section, one patient (14.3%) with twin pregnancy had vaginal delivery with the help of suction cup and forceps, and another patient (14.3%) continued the pregnancy. All patients recovered well after administration of oxygen, diuresis, and other supportive therapy. Conclusion: Atosiban may cause acute pulmonary edema in patients with underlying risk factors. This complication remains rare, but caution during tocolytic treatment using atosiban is recommended.

Hydatidiform mole is a malignant entity included in the gestational trophoblastic diseases. It usually produces pregnancy hormones such as beta-human chorionic gonadotropin (β-hCG), which in turn stimulates endogenous thyroid hormone production. We report the case of a high-risk complete invasive hydatidiform mole with pulmonary metastasis and associated paraneoplastic syndrome. The patient is a 30-year-old woman who presented symptoms of pregnancy and metrorrhagia. A uterine mass was detected. Urine β-hCG was found negative. In serum, 2,662,000 mIU/mL (normal range:

Abstract Background Noncardiogenic pulmonary edema (NCPE) is a rare and life-threatening allergy-like reaction to the intravascular injection of a nonionic radiographic agent. We first describe a very rare case of fatal NCPE after the intravenous injection of nonionic, iso-osmolar iodine contrast media. Case presentation A 55-year-old male patient was admitted to the hospital with esophageal cancer. After the intravenous administration of 100 mL iodixanol, the patient first exhibited digestive tract symptoms, including abdominal pain, diarrhea, and vomiting, with no dyspnea, rash, itching, or throat edema. He received anti-allergy treatment, but his symptoms did not improve; instead, he further developed pulmonary edema. Arterial blood gas analysis results were as follows: pH, 7.08; PO2, 70 mm Hg; PCO2, 40 mm Hg; and SaO2, 52%. Then, the patient received emergent tracheal intubation and ventilation to assist breathing, and he was transferred to the intensive care unit (ICU) for further treatment. In the ICU, the patient developed shock and respiratory and circulatory failure; therefore, he received shock resuscitation, acidosis correction, muscle relaxants to lower the work of breathing, and cardiotonic therapy. The patient eventually died. During the ICU period, emergency bedside color ultrasound showed a diffuse B line in both lungs, and the size of the cardiac cavity was normal, but the ventricular rate was extremely fast. Chest radiography showed pulmonary edema with a normal cardiac silhouette, and the brain natriuretic peptide (BNP) level was in the normal range. Conclusions NCPE is a rare and critical allergy-like reaction to the use of a nonionic iso-osmolar radiocontrast contrast medium. Clinicians should pay very close attention to digestive tract manifestations during the medical observation of patients, as gastrointestinal manifestations may be the prodromal symptoms of NCPE caused by iso-osmolar contrast medium injection.

Critical aortic valve stenosis in newborns is the cause of a severe clinical condition with the onset of symptoms during first hours after birth. We present a clinical case of a successful surgical correction of a critical aortic stenosis using a hybrid method applied in a newborn during the first day of life. The infant was diagnosed with a hypoplastic left heart complex with an intact atrial septum (aortic and mitral valves stenosis variant), that led to the cardiogenic shock and acute pulmonary edema. The procedure included bilateral banding of the pulmonary artery branches and atrioseptostomy with stenting of the interatrial septum. The surgery was performed through a median sternotomy.

We present the case of an 80-year-old female with acute pulmonary edema and a dual chamber pacemaker with intermittent short AV delays in the surface ECG after blocked premature atrial contractions (PACs). The behavior was consistent with the programmed Window of Atrial Rate Acceleration Detection (WARAD) and did not require further parameter modifications. As most cardiologists and emergency department physicians are not familiar with brand-specific algorithms, we believe that this case report will make these noncompetitive atrial pacing algorithms more accessible to non-cardiologists., (© 2024 The Author(s).

In the context of Acute Pulmonary Edema (APE), the old school moto was LMNOP, for "Lasix-Morphine-Nitrates-Oxygen-Positive Pressure". However, this mnemonic, while not entirely inaccurate, deserves revision or at least a slight reinterpretation. APE remains a well-known condition in emergency departments, with a high mortality rate. Despite its prevalence, management recommendations have seen minimal evolution over the past four decades, with references dating back to a 1974 article in the New England Journal of Medicine that already advocated for the triplet of Lasix-Oxygen-Nitrates, a recommendation still present in the 2021 ESC guidelines. In this article, we will discuss the management and potential updates in the treatment of this common pathology.

Introduction: Since acute pulmonary edema is one of the reasons for hospitalization of pregnant women in intensive care units and failure to timely diagnose it has dangerous complications for mother and fetus. This study was performed with aim to determine the consequences of acute pulmonary edema in pregnant women referred to the hospitals in Tabriz. Methods: In this cohort study conducted in 2013-2014 in Tabriz educational and medical centers, 2750 pregnant women with high-risk pregnancies were evaluated for acute pulmonary edema, and neonatal outcomes (first and fifth minute Apgar scores, neonatal weight, fetal death, birth time were evaluated in women with a definitive diagnosis of acute gestational edema. Data were analyzed by SPSS statistical software (version 17) and t-test and Chi-square test. P

Abstract Background Recombinant tissue plasminogen activator (rt-pa) is the first-line drug for the treatment of acute ischemic stroke, and can lead to some complications.There were rare reports of death due to acute pulmonary edema during rt-pa thrombolysis treatment. Case presentation This study reports a 30-year-old man was diagnosed with acute ischemic stroke and underwent rt-pa thrombolytic therapy. Finally he died despite active rescue. Conclusions The autopsy revealed that he died of acute pulmonary edema. This case suggests that it is necessary to pay close attention to the changes of vital signs during thrombolysis and be aware of possibility of pulmonary edema during thrombolysis.

Abstract Background Noninvasive ventilation (NIV) is recognized as first line ventilatory support for the management of acute pulmonary edema (APE) and chronic obstructive pulmonary disease (COPD) exacerbations. We aimed to study the prehospital management of patients in acute respiratory distress with an indication for NIV and whether they received it or not. Methods This retrospective study included patients ≥18 years old who were cared for acute respiratory distress in a prehospital setting. Indications for NIV were oxygen saturation (SpO2) 25/min with a presumptive diagnosis of APE or COPD exacerbation. Study population characteristics, initial and at hospital vital signs, presumptive and definitive diagnosis were analyzed. For patients who received NIV, dyspnea level was evaluated with a dyspnea verbal ordinal scale (D-VOS, 0-10) and arterial blood gas (ABG) values were obtained at hospital arrival. Results Among the 187 consecutive patients included in the study, most (n = 105, 56%) had experienced APE or COPD exacerbation, and 56 (30%) received NIV. In comparison with patients without NIV, those treated with NIV had a higher initial RR (35 ± 8/min vs 29 ± 10/min, p

• Data on the role of Uric Acid (UA) as a determining factor of Heart Failure related issue in Acute Coronary Syndrome (ACS) patients are scanty. • UA was confirmed to be significantly associated with Acute Heart Failure, Cardiogenic Shock, Non Invasive Ventilation and Ejection Fraction in ACS patients. • Evaluation of UA in ACS patients could help to identify the one with the worst heart failure related outcomes. We focused on the role of Uric Acid (UA) as a possible determinant of Heart Failure (HF) related issues in Acute Coronary Syndromes (ACS) patients. Main outcomes were acute HF and cardiogenic shock at admission, secondary outcomes were the use of Non Invasive Ventilation (NIV) and the admission Left Ventricular Ejection Fraction (LVEF). We consecutively enrolled 1269 ACS patients admitted to the cardiological Intensive Care Unit of the Niguarda and San Paolo hospitals (Milan, Italy) from June 2016 to June 2019. Median age was 68 (first-third quartile 59–77) years and males were 970 (76%). All the evaluated outcomes occurred more frequently in the hyperuricemic subjects (UA higher than 6 mg/dL for females and 7 mg/dL for males, n = 292): acute HF 35.8 vs 11.1% (p < 0.0001), cardiogenic shock 10 vs 3.1% (p < 0.0001), NIV 24.1 vs 5.1% (p < 0.0001) and lower admission LVEF (42.9±12.8 vs 49.6±9.9, p < 0.0001). By multivariable analyses, UA was confirmed to be significantly associated with all the outcomes with the following Odds Ratio (OR): acute HF OR = 1.119; 95% CI 1.019;1.229; cardiogenic shock OR = 1.157; 95% CI 1.001;1.337; NIV use OR = 1.208; 95% CI 1.078;1.354; LVEF β = -0.999; 95% CI -1.413;-0.586. We found a significant association between UA and acute HF, cardiogenic shock, NIV use and LVEF. Due to the cross-sectional nature of our study no definite answer on the direction of these relationship can be drawn and further longitudinal study on UA changes over time during an ACS hospitalization are needed.

Hydatidiform mole is a malignant entity included in the gestational trophoblastic diseases. It usually produces pregnancy hormones such as beta-human chorionic gonadotropin (β-hCG), which in turn stimulates endogenous thyroid hormone production. We report the case of a high-risk complete invasive hydatidiform mole with pulmonary metastasis and associated paraneoplastic syndrome. The patient is a 30-year-old woman who presented symptoms of pregnancy and metrorrhagia. A uterine mass was detected. Urine β-hCG was found negative. In serum, 2,662,000 mIU/mL (normal range: <5) was found, together with parameters of severe hyperthyroidism. The patient underwent uterine curettage with diagnostic and therapeutic means. At that precise moment, her pregnancy-like symptoms worsened and she developed restlessness, tachycardia, diaphoresis, dyspnea at rest, and peripheral edema. A scan showed bilateral pulmonary nodules suggestive of metastasis, acute pulmonary edema, and bilateral pleural effusion without signs of pulmonary thromboembolism. At that time, she presented a free T4 of 2.34 ng/dL (normal range: 0.8–1.8 ng/dL), causing a thyroid storm with secondary cardiac dysfunction. The patient was treated with corticosteroid therapy to decrease peripheral conversion of thyroid hormone T4 to active T3. Her symptoms remitted within 8 h. After 48 h, T4 level was 1.2 ng/dL while serum β-hCG was 80,000 mIU/mL, with a positive urine result. The change in the urine analysis is due to the "hook effect" of the reactive test. An effective chemotherapy treatment was started according to the EMA-CO scheme, remaining free of disease at present. Knowing paraneoplastic syndromes is necessary to achieve the best clinical management and to start treatment early. [ABSTRACT FROM AUTHOR]

Background In imported falciparum malaria, systemic inflammation with increased capillary permeability can cause life-threatening complications, such as acute pulmonary edema (APO) or adult respiratory distress syndrome (ARDS). This observational study assessed the association of the admission serum albumin level (ALB) and C-reactive protein to albumin ratio (CRP/ALB) with disease severity and these respiratory complications. Methods All adult cases hospitalized during 2001–2015 in the Charité University Hospital, Berlin, with ALB and CRP values measured upon admission, were retrospectively analysed. Results Seventy-six patients were enrolled (26 female, median age: 37 y), 60 with uncomplicated malaria and 16 with severe malaria (SM). SM was associated with lower ALB (p<0.0001) and higher CRP/ALB (p<0.0001) values; the areas under the receiver operator curves (AUROCs) were 0.85 (95% CI 0.74 to 0.96) for ALB and 0.88 (95% CI 0.80 to 0.97) for CRP/ALB. Radiologic changes consistent with APO/ARDS were detectable in 5 of 45 admission chest X-rays performed (11.1%); the AUROCs were 0.86 (95% CI 0.74 to 0.99) for ALB and 0.91 (95% CI 0.82 to 0.99) for CRP/ALB. Conclusions Diminished admission ALB levels and elevated CRP/ALB ratios are associated with disease severity and respiratory complications in imported falciparum malaria. These readily and ubiquitously available markers may facilitate early identification of at-risk patients. [ABSTRACT FROM AUTHOR]

Abstract Background Hand, foot, and mouth disease (HFMD) is an acute infectious disease caused by human enterovirus 71 (EV71), coxsackievirus, or echovirus, which is particularly common in preschool children. Severe HFMD is prone to cause pulmonary edema before progressing to respiratory and circulatory failure; thus hemodynamic monitoring and fluid management are important to the treatment process. Methods We did a review of young patients who had been successfully treated in our department for severe HFMD, which had been caused by EV71. A total of 20 patients met the inclusion criteria. Eight cases were monitored by the pulse indicator continuous cardiac output (PiCCO) technique, and fluid management was administered according to its parameters. With regard to the treatment with PiCCO monitoring, patients were divided into two groups: the PiCCO group (8 patients) and the control group (12 patients). The groups were then compared comprehensively to evaluate whether PiCCO monitoring could improve patients’ clinical outcomes. Results After analysis, the findings informed that although PiCCO failed to shorten the length of ICU stay, reduce the days of vasoactive drug usage, or lower the number of cases which required mechanical ventilation, PiCCO did reduce the incidence of fluid overload (p = 0.085) and shorten the days of mechanical ventilation (p = 0.028). After effective treatment, PiCCO monitoring indicated that the cardiac index (CI) increased gradually(p

Background: Noncardiogenic pulmonary edema (NCPE) is a rare and life-threatening allergy-like reaction to the intravascular injection of a nonionic radiographic agent. We first describe a very rare case of fatal NCPE after the intravenous injection of nonionic, iso-osmolar iodine contrast media. Case presentation A 55-year-old male patient was admitted to the hospital with esophageal cancer. After the intravenous administration of 100 mL iodixanol, the patient first exhibited digestive tract symptoms, including abdominal pain, diarrhea, and vomiting, with no dyspnea, rash, itching, or throat edema. He received anti-allergy treatment, but his symptoms did not improve; instead, he further developed pulmonary edema. Arterial blood gas analysis results were as follows: pH, 7.08; PO2, 70 mm Hg; PCO2, 40 mm Hg; and SaO2, 52%. Then, the patient received emergent tracheal intubation and ventilation to assist breathing, and he was transferred to the intensive care unit (ICU) for further treatment. In the ICU, the patient developed shock and respiratory and circulatory failure; therefore, he received shock resuscitation, acidosis correction, muscle relaxants to lower the work of breathing, and cardiotonic therapy. The patient eventually died. During the ICU period, emergency bedside color ultrasound showed a diffuse B line in both lungs, and the size of the cardiac cavity was normal, but the ventricular rate was extremely fast. Chest radiography showed pulmonary edema with a normal cardiac silhouette, and the brain natriuretic peptide (BNP) level was in the normal range.Conclusions: NCPE is a rare and critical allergy-like reaction to the use of a nonionic iso-osmolar radiocontrast contrast medium. Clinicians should pay very close attention to digestive tract manifestations during the medical observation of patients, as gastrointestinal manifestations may be the prodromal symptoms of NCPE caused by iso-osmolar contrast medium injection.

Objective: The objective is to study the clinical profile of patients presenting to an emergency department with acute pulmonary edema. Materials and Methods: This is a prospective, observational study performed in 100 patients presenting to the Emergency Department of Amrita Institute of Medical Sciences (Kochi) with acute pulmonary edema. Patients were selected according to the inclusion and exclusion criteria. The variables analyzed were age, sex, comorbidities, ABG, cardiac enzymes, NT-prob-type natriuretic peptide, chest X-ray, electrocardiogram, and clinical outcome. Results: Of the 100 patients, 64% were male and 36% were female. Age group affected were between 51 and 70 years (52 patients) and between 71 and 90 years (32 patients). Data analysis revealed that the cause of pulmonary edema in 63 patients was cardiogenic and 37 patients was chronic kidney disease. Conclusion: In this study, the incidence was more in males, nearly twice that of females. The most commonly affected age group was between 51 and 70 years of age (52%). We found that the most common cause of pulmonary edema was congestive heart failure (63%) followed by chronic kidney diseases (37%). Moreover, the most common ABG finding was high anion gap metabolic acidosis, mostly lactic acidosis.

The aim of the current study was to describe lung ultrasonography (LUS) characteristics and to evaluate the agreement between LUS and chest radiography (CXR) in diagnosis of four conditions causing most acute dyspnea in children, namely, pneumonia, pleural effusion, pneumothorax and acute pulmonary edema in children at a teaching hospital in Vietnam. We reviewed the records of the chidren between January and June 2018, who presented to emergency department (ED) or pediatric intensive care unit (PICU) at children hospital 1 (CH1) with acute dyspnea and had final diagnosis of one of four etiologies including pneumonia, pleural effusion, pneumothorax and acute pulmonary edema. All patients underwent CXR and LUS at the time of admission. Eighty-one children with acute dyspnea including pneumonia (n=65, 80%), pleural effusion (n=9, 11%), pneumothorax (n=3, 4%) and acute pulmonary edema (n=4, 5%) were enrolled. LUS was identified among 100% of cases with pleural effusion and pneumothorax (CXR only showed 73.3% and 50%, respectively); 92.3% of cases with pneumonia (CXR showed 93.8%) and only 75% of cases with acute pulmonary edema (CXR showed 50%). When comparing LUS with CXR, we noticed a good agreeement between the 2 methods in the diagnosis of pneumonia (kappa=0.64, p

Context: Acute pulmonary oedema (APO) in pregnant women is associated with increased maternal morbidity and mortality. Aim: The aim of this study was to evaluate the risk reduction strategy by a protocol-based approach to the management of APO in pregnancy in a low-resource center. Settings and Design: The study was conducted in a single obstetric tertiary care public sector hospital for 12 months. Materials and Methods: The pregnant women admitted with acute shortness of breath (SOB) were divided into two groups based on the implementation of pulmonary edema protocol. The data before protocol (Group A) and after (Group B) were compared. Results: A total of 38 patients were admitted with acute SOB. The incidence of APO was 0.10% (95% CI: 0.08,0.14). Majority (Group A: 92.87%; Group B: 81.25%) were admitted in the third trimester. Hypertension was the most common etiology (71.42% in Group A; 81.25% in Group B), followed by cardiovascular causes (42.85% in Group A; 6.25% in Group B) and sepsis (21.42% in Group A; 18.75% in Group B). Caesarean section was carried out in 57.14% in Group A; 62.5% in Group B. Noninvasive Ventilation (NIV) was started in 8 of 16 cases in Group B. Regional anesthesia was used in 87.5% in Group A and 100% in Group B. The maternal mortality was 9 (64.28%) in Group A as compared to 1 (6.25%) in Group B; P = 0.001. Conclusion: The protocol-based algorithm for APO in pregnancy decreases the maternal mortality. Hypertensive disorders of pregnancy are the most common cause followed by cardiac disease. NIV is useful in APO.

Background: Noninvasive ventilation (NIV) is recognized as first line ventilatory support for the management of acute pulmonary edema (APE) and chronic obstructive pulmonary disease (COPD) exacerbations. We aimed to study the prehospital management of patients in acute respiratory distress with an indication for NIV and whether they received it or not. Methods: This retrospective study included patients ≥18 years old who were cared for acute respiratory distress in a prehospital setting. Indications for NIV were oxygen saturation (SpO2) <90% and/or respiratory rate (RR) >25/min with a presumptive diagnosis of APE or COPD exacerbation. Study population characteristics, initial and at hospital vital signs, presumptive and definitive diagnosis were analyzed. For patients who received NIV, dyspnea level was evaluated with a dyspnea verbal ordinal scale (D-VOS, 0-10) and arterial blood gas (ABG) values were obtained at hospital arrival. Results: Among the 187 consecutive patients included in the study, most (n = 105, 56%) had experienced APE or COPD exacerbation, and 56 (30%) received NIV. In comparison with patients without NIV, those treated with NIV had a higher initial RR (35 ± 8/min vs 29 ± 10/min, p < 0.0001) and a lower SpO2 (79 ± 10 vs 88 ± 11, p < 0.0001). The level of dyspnea was significantly reduced for patients treated with NIV (on-scene D-VOS 8.4 ± 1.7 vs 4.4 ± 1.8 at admission, p < 0.0001). Among the 131 patients not treated with NIV, 41 (31%) had an indication. In the latter group, initial SpO2 was 80 ± 10% in the NIV group versus 86 ± 11% in the non-NIV group (p = 0.0006). NIV was interrupted in 9 (16%) patients due to either discomfort (n = 5), technical problem (n = 2), persistent desaturation (n = 1), or vomiting (n = 1). Conclusions: The results of this study contribute to a better understanding of the prehospital management of patients who present with acute respiratory distress and an indication for NIV. NIV was started on clinically more severe patients, even if predefined criteria to start NIV were present. NIV allows to improve vital signs and D-VOS in those patients. A prospective study could further elucidate why patients with a suspected diagnosis of APE and COPD are not treated with NIV, as well as the clinical impact of the different strategies. Trial registration: The study was approved by our institutional ethical committee (CER-VD 2020-01363). [ABSTRACT FROM AUTHOR]

Background: Hand, foot, and mouth disease (HFMD) is an acute infectious disease caused by human enterovirus 71 (EV71), coxsackievirus, or echovirus, which is particularly common in preschool children. Severe HFMD is prone to cause pulmonary edema before progressing to respiratory and circulatory failure; thus hemodynamic monitoring and fluid management are important to the treatment process.Methods: We did a review of young patients who had been successfully treated in our department for severe HFMD, which had been caused by EV71. A total of 20 patients met the inclusion criteria. Eight cases were monitored by the pulse indicator continuous cardiac output (PiCCO) technique, and fluid management was administered according to its parameters. With regard to the treatment with PiCCO monitoring, patients were divided into two groups: the PiCCO group (8 patients) and the control group (12 patients). The groups were then compared comprehensively to evaluate whether PiCCO monitoring could improve patients' clinical outcomes.Results: After analysis, the findings informed that although PiCCO failed to shorten the length of ICU stay, reduce the days of vasoactive drug usage, or lower the number of cases which required mechanical ventilation, PiCCO did reduce the incidence of fluid overload (p = 0.085) and shorten the days of mechanical ventilation (p = 0.028). After effective treatment, PiCCO monitoring indicated that the cardiac index (CI) increased gradually(p < 0.0001), in contrast to their pulse (P, p < 0.0001), the extra vascular lung water index (EVLWI, p < 0.0001), the global end diastolic volume index (GEDVI, p = 0.0043), and the systemic vascular resistance index (SVRI, p < 0.0001), all of which decreased gradually.Conclusion: Our study discovered that PiCCO hemodynamic monitoring in young children with severe HFMD has some potential benefits, such as reducing fluid overload and the duration of mechanical ventilation. However, whether it can ameliorate the severity of the disease, reduce mortality, or prevent multiple organ dysfunction remain to be further investigated. [ABSTRACT FROM AUTHOR]

Hypertension is one of the most powerful and modifiable risk factors for the development, progression and even decompensation of heart failure. Uncontrolled hypertension increases to frequency of heart failure hospitalizations by increase sympathetic tone. Catheter-based renal denervation has been shown to reduce blood pressure in the treatment of multidrug-resistant hypertension. We report the improvement in clinical status after renal denervation in a 47-year-old male patient with a history of hypertension, chronic ischemic heart failure, and recurrent hospitalizations for acute hypertensive pulmonary edema despite optimal medical therapy., (Copyright © 2024 SEH-LELHA.

Pulmonary edema is one of the most serious complications of preeclampsia, that should be ruled out in case of dyspnea in a pregnant woman, especially in the context of preeclampsia. It is an indication of urgent pregnancy-termination. Many theories have been proposed to explain this phenomenon, such as hypervolaemia, left ventricular failure and pulmonary capillary leakage, but it is still not well understood. The prognosis is generally good after adequate management and symptoms completely disappear withing a few days of delivery. We report a case of a 30 year old woman with pulmonary edema that complicated preeclampsia and discuss the management options.

Eklampsia adalah kelainan pada kehamilan yang ditandai dengan peningkatan tekanan darah disertai dengan proteinuria positif dan kejang yang muncul setelah minggu ke-20 kehamilan. Eklampsia dapat menimbulkan komplikasi terhadap ibu dan janin. Diantara komplikasi terhadap ibu yang muncul akibat eklampsia adalah edema paru akut. Edema paru akut terjadi pada 0,08% hingga 1,5% kehamilan dan merupakan salah satu penyebab kematian ibu hamil sehingga tergolong suatu keadaan darurat dan memerlukan penanganan segera. Faktor sirkulasi angiogenik, penurunan tekanan onkotik koloid, disfungsi sel endotel, atau peningkatan tekanan intravaskular disertai dengan peningkatan beban jantung diduga menjadi faktor penyebab terjadinya edema paru akut pada eklampsia. Penegakan diagnosa serta pemberian terapi yang tepat pada edema paru akut harus dilakukan sesegera mungkin untuk menurunkan angka mortalitas dan morbiditasnya. Terapi yang diberikan meliputi pemberian obat -obatan dan atau bantuan ventilasi mekanik. Penggunaan bantuan ventilasi mekanik dilakukan dengan pendekatan strategi lung recruitment yang bertujuan untuk memperbaiki oksigenasi paru dan mampu meningkatkan kemampuan penyapihan ventilator serta mencegah kerusakan paru iatrogenik. Disamping pemantauan hemodinamik secara berkesinambungan, penggunaan ventilasi mekanik merupakan indikasi bagi pasien eklampsia dengan edema paru akut untuk menjalani perawatan di ruang rawat intensif. Acute Pulmonary Edema in Patient with Eclampsia: are Really Need a Intensive Care Unit Treatment? Abstract Eclampsia is a disorder in pregnancy which is characterized by an increase in blood pressure accompanied by positive proteinuria and seizures that appear after the 20th week of pregnancy. Eclampsia can cause complications for the mother and fetus. Among the complications of the mother that arise due to eclampsia are acute pulmonary edema. Acute pulmonary edema occurs in 0.08% to 1.5% of pregnancy and is one of the causes of death of pregnant women so it is classified as an emergency and requires immediate treatment. Angiogenic circulation factors, a decrease in colloid oncotic pressure, endothelial cell dysfunction, or an increase in intravascular pressure accompanied by an increase in cardiac load are thought to be factors causing the occurrence of acute pulmonary edema in eclampsia. The diagnosis and the provision of appropriate therapy in acute pulmonary edema must be done as soon as possible to reduce its mortality and morbidity. The therapy provided includes the administration of medicines and or mechanical ventilation assistance. The use of mechanical ventilation assistance is carried out with a lung recruitment strategy approach that aims to improve lung oxygenation and be able to improve ventilator weaning capabilities and prevent iatrogenic lung damage. In addition to continuous hemodynamic monitoring, the use of mechanical ventilation is an indication for eclampsia patients with acute pulmonary edema to undergo treatment in the intensive care unit.

Laurence Pincet,1 Gabriele Lecca2 1ENT Surgery Department, University Hospital Centre (CHUV), Lausanne, Switzerland; 2Department of Internal Medicine, Riviera – Chablais Hospital, Monthey Site, Route de Morgins, Monthey, Switzerland Background: Non-cardiogenic pulmonary edema (NCPE) after intravenous (iv) administration of non-ionic radiocontrast media (RCM) is a rare but life-threatening complication. In a context of emergency, its diagnosis is difficult. Case report: We report the case of a 55-year-old woman who developed an acute pulmonary edema following iv infusion of non-ionic, low-osmolar RCM during abdominal CT scan. She needed a 24-hour hospitalization in intensive care unit for an acute hypoxemic dyspnea. She was falsely treated at first for an anaphylactic reaction, and then for a cardiac failure. She improved with cortisone and diuretic treatment. Conclusion: Although NCPE has been rarely reported after RCM injection, it remains an acute severe complication that has to be considered. The differential diagnosis involves multiple pathogenic patterns giving furthermore complexity in choosing an appropriate treatment.

Introduction: The necessity of rapid preload and afterload reduction in patients with decompensated congestive heart failure (CHF) and acute pulmonary edema (APE) is well established. In the hospital setting, intravenous (IV) nitroglycerin demonstrates improved patient morbidity and mortality. However, prehospital treatment is typically limited to sublingual nitroglycerin at doses that often do not affect afterload. In this study, we assessed feasibility, safety and effectiveness of prehospital IV bolus nitroglycerin in decompensated CHF patients with APE. Methods: This was a retrospective chart review of all emergency medical services (EMS) and ED patient care records of subjects treated for presumed decompensated CHF with APE with bolus-dose IV nitroglycerin between March 15, 2018 and March 15, 2019 by a large, suburban, county-based EMS service in Texas. Inclusion criteria for treatment included both hypertension (systolic blood pressure [SBP] > 160 mmHg) and acute respiratory distress with a paramedic clinical impression of decompensated CHF with APE. Treatment consisted of a 1 mg nitroglycerin bolus, repeated in 5 minutes if SBP > 160 mmHg. Results: During the study period, 48 patients were treated with IV bolus nitroglycerin. Initially, the median (IQR) SBP was 211.0 mmHg (190.0–229.5), 5-minutes post IV NTG was 177.0 mmHg (155.0–199.0), and upon ED arrival was 181.5 mmHg (157.0–207.0). 5 minutes after IV nitroglycerin, the median pulse decreased from 113 (96–124) to 103 (85–117) beats per minute and the median oxygen saturation increased from 86% (74–89) to 98% (96–99). Based on hospital records review, 45/48 (94%) of patients treated with IV nitroglycerin were found to have CHF with APE. A single episode of transient hypotension, which resolved without treatment, did occur during EMS transport. Conclusion: This case series found that patients who were treated by paramedics with IV NTG had improved systolic blood pressure and oxygen saturation upon ED arrival as compared to their initial presentation. Over 90% of these patients were correctly identified by paramedics as having CHF with APE based on ED evaluation. Only one patient had an adverse event, which was transient hypotension that did not require intervention. [ABSTRACT FROM AUTHOR]

Stonefish sting lethality in man has been scarcely documented since the middle of the 20th century. We report three clinical cases, including one fatality, emphasizing the cardiovascular toxicity of the Synanceia verrucosa venom, and its potentially lethal effects. All clinical data have been recently collected in New Caledonia and French Polynesia. • Stonefish sting is to be considered as a life-threatening event. • Envenomation may lead to acute pulmonary edema and/or cardiopulmonary arrest. • Prognosis relies on early cardiopulmonary resuscitation and on supportive respiratory care. • Stonefish antivenom is recommended in severe stonefish envenomation.

HELLP syndrome is a combination of symptoms described as hemolysis, elevated liver enzymes and low platelets. HELLP is a common life-threatening complication of pregnancy thought to be a variant or complication of preeclampsia. In this case report, we aimed to present a woman with acute postpartum HELLP syndrome complicated by pulmonary edema after caesarean section following severe preeclampsia. Our experience suggests that early detection of HELLP syndrome and timely management will bring good outcomes.

Background: Heart failure with reduced ejection fraction (HFrEF) poses significant health risks. Midodrine for maintaining blood pressure in HFrEF, requires further safety investigation. This study explores midodrine's safety in HFrEF through extensive matched analysis. Methods: Patients with HFrEF (LVEF <50%) without malignancy, non-dialysis dependence, or non-orthostatic hypotension, were enrolled between 28 August 2013, and 27 August 2023. Propensity score matching (PSM) created 1:1 matched groups. Outcomes included mortality, stage 4 and 5 chronic kidney disease (CKD), emergency room (ER) visits, intensive care unit (ICU) admissions, hospitalizations, and respiratory failure. Hazard ratios (HR) with 95% confidence intervals (95% CI) were calculated for each outcome, and Kaplan-Meier survival analysis was performed. Subgroup analyses were conducted based on gender, age (20-<65 vs. ≥65), medication refill frequency, and baseline LVEF. Results: After 1:1 PSM, 5813 cases were included in each group. The midodrine group had higher risks of respiratory failure (HR: 1.16, 95% CI: 1.08-1.25), ICU admissions (HR: 1.14, 95% CI: 1.06-1.23), hospitalizations (HR: 1.21, 95% CI: 1.12-1.31), and mortality (HR: 1.090, 95% CI: 1.01-1.17). Interestingly, midodrine use reduced ER visits (HR: 0.77, 95% CI: 0.71-0.83). Similar patterns of lower ER visit risk and higher risks for ICU admissions, respiratory failure, and overall hospitalizations were observed in most subgroups. Conclusion: In this large-scale study, midodrine use was associated with reduced ER visits but increased risks of respiratory failure, prolonged ICU stays, higher hospitalizations, and elevated mortality in HFrEF patients. Further research is needed to clarify midodrine's role in hemodynamic support and strengthen existing evidence., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Wu, Chen and Tsai.)
