Right-sided heart failure (RHF) diagnosed at point-of-care-ultrasonography examination of critical patients may reveal an acute disease, such as pulmonary embolism (PE), requiring emergency thrombolytic treatment. However, acute respiratory distress syndrome (ARDS) and PE leading to acute RHF may exhibit very similar echocardiographic features. We report the case of a 27-year-old pregnant woman diagnosed with ARDS due to septic abortion, and in whom ARDS mimicked PE both clinically and on echocardiography. Such similarity may lead to inappropriate administration of thrombolytic therapy and/or delay the correct treatment. Lung ultrasonography may help avoiding this pitfall.

The primary aim of this study was to determine the value of the inferior vena cava (IVC) ultrasound in the decision to hospitalise acute decompensated heart failure (ADHF) patients. Our secondary aim was to find the most successful IVC measurement method in monitoring volume status.ADHF patients were accepted over a 1-year period in this study. Patients' vital signs, laboratory tests and IVC measurements measured by six methods (in B- and M-mode; maximum, minimum diameter and caval index) performed on an hourly basis were recorded. The presence of any statistically significant difference between the IVC measurement methods, laboratory tests and vital parameters between the hospitalised and discharged patients was calculated. ROC curves were produced in order to determine the ability of parameters to differentiate two groups. Spearman's correlation test was used to investigate correlation between the IVC measurement methods and patients' urine outputs.A total of 71 patients were included in the study; 42 of these were hospitalised and 29 were discharged. Potassium, brain natriuretic peptide, respiration rate, urine output, maximum and minimum IVC diameters differed significantly between the two groups. Minimum IVC diameter measured in M-mode was identified as a weak marker with 65% sensitivity and 64% specificity (+PPV: 73%; -NPV:54%) for hospitalisation. Change in maximum IVC diameter measured in B-mode exhibited a high degree of correlation with change in body fluid (cc: 0.802).IVC ultrasound may have a limited value in the decision to hospitalise ADHF patients. But Maximum IVC diameter may be an ideal method for monitoring hypervolemic patients' volume status.NCT02725151.

Noninvasive mechanical ventilation (NIMV) has a relevant role in the treatment of critically ill patients displaying severe dyspnea. Continuous positive airway pressure (CPAP), a method of NIMV, is also widely used in the management of acute heart failure, chronic obstructive pulmonary disease (COPD) exacerbation, and symptomatic sleep apnea. However, numerous traumatic complications of CPAP treatment in the face region, head, and thorax have been reported and may be related to the application of a continuous positive high pressure to the airway. Conversely, we have observed no complications due to CPAP-related increased intra-abdominal pressure. In this article, we describe a clinical case of a patient with an acute rectus sheath hematoma during CPAP treatment. This previously unreported complication demonstrates that CPAP should be carefully used in patients with exacerbated COPD with difficulty in expiration.

Background Emphysematous cholecystitis (EC) is a form of cholecystitis with high mortality rates more commonly seen in patients with medical histories such as diabetes, hypertension, and peripheral vascular disease. The common features of these medical diseases are impaired pain perception, particularly abdominal pain, due to advanced age and peripheral neuropathies. Accurate evaluation of characteristics observed at ultrasonography, the method of first choice in the diagnosis of EC, is therefore highly important in these patients. Case Report This study reports a case of the champagne sign, rarely seen in EC, together with other EC findings. Why Should an Emergency Physician Be Aware of This? The champagne sign is a little-known sonographic finding that is evidence of the presence of gas in the gallbladder. The champagne sign that will be detected while evaluating the hepatobiliary system on bedside ultrasound is one of the valuable findings in the diagnosis of emphysematous cholecystitis with high mortality.

New substances are constantly being added to the content of synthetic cannabinoids (SCs). SCs can affect the cardiovascular system and cause hypotension and bradycardia, myocardial infarction, atrial fibrillation, prolonged QTc, and Mobitz type II atrioventricular block. However, no cases associated with ventricular fibrillation (VF) have been reported to date. We report a case of a 26-year-old male patient admitted to the emergency department due to altered consciousness after SC use and requiring prolonged cardiopulmonary resuscitation due to resistant VF and cardiogenic shock.

OBJECTIVES Blood hemoglobin concentration measurements using a spectrophotometric method (SpHb), and inferior vena cava ultrasonography (IVC-US) are noninvasive methods used to follow-up hemorrhages. We compared their efficacy using voluntary blood donation as a model of moderate (approx. 500 mL) blood loss. METHODS In this prospective observational study enrolling blood-donor volunteers (BD) and matched controls, we recorded SpHb, IVC diameters, and vital signs. Changes in variables from baseline were compared between BD and controls using the paired t test and Wilcoxon signed rank test. RESULTS We included 118 subjects in the BD group and 95 healthy subjects in the control group. Changes in IVC maximum diameter, IVC minimum diameter, pulse rate, mean arterial pressure, pulse pressure, and shock index, but not in other variables, were significantly different in the BD and the control group (P

OBJECTIVES The purpose of this study was to determine the success of mitral valve movements in the estimation of left ventricular ejection fraction (LVEF). METHODS Adult patients whose principal symptom was dyspnea were included in this prospective observational study. The distance from the anterior mitral valve (AMV) to the interventricular septum (IVS) during early diastole was measured first in B-mode in the parasternal long axis (PLAX) named parasternal long axis-anterior leaflet septal separation. Second, the AMV-IVS distance was measured in M-mode in the PLAX named E-point septal separation. Third, AMV-IVS distance was measured in B-mode in the apical 4-chamber view named apical 4-chamber view-anterior leaflet septal separation. Finally, maximum distance between the 2 mitral leaflets in the apical 4-chamber view was measured and named mitral valve leaflet separation. Comprehensive echocardiography was performed by an experienced cardiologist. Correlation was calculated between mitral valve measurements and LVEF. Cutoff values were determined using receiver operating characteristic curves and the chi-square test. RESULTS A total of 118 patients were included in the study. Parasternal long axis-anterior leaflet septal separation, E-point septal separation, and apical 4-chamber view-anterior leaflet septal separation were highly correlated with LVEF (correlation coefficient, -0.848, -0.833, and-0.822 [P

This study aims to determine the site of and the best sonographic method for measurement of inferior vena cava (IVC) diameter in volume status monitoring.This observational before-and-after study was performed at the intensive care unit of the emergency department. It included hypotensive adult patients with suspected sepsis who were recommended to receive at least 20 mg/kg fluid replacement by the emergency physician. The patients were fluid replaced at a rate of 1000 mL/h, and maximum and minimum IVC diameters were measured and the Caval index calculated sonographically via both B-mode and M-mode. Hence, IVC's volume response was assessed by a total of 6 parameters, 3 each in M-mode and B-mode. Freidman test was used to assess the change in IVC diameter with fluid replacement. Wilcoxon test with Bonferroni correction was used to determine which measurement method more sensitively measured IVC diameter change.Twenty-eight patients with a mean age of 71.3 were included in the final analysis.The IVC diameter change was significant with all 6 methods (P.001). The IVC minimum diameter change measured on M-mode during inspiration (M-mode i) was the only measurement method that significantly showed diameter change with each 500-mL fluid replacements. The initial and the subsequent M-mode i values after each 500 mL of fluid were 5.65 ± 3.34; 8.05 ± 3.66; 10.16 ± 3.61, and 11.21 ± 2.94, respectively (P.001, P.002, and P.003, respectively).Inferior vena cava diameter was changed by fluid administration. The M-mode i method that most sensitively measures that change may be the most successful method in volume status monitoring.

Study objective We aimed to determine the role of inferior vena cava (IVC) diameter in making a differentiation between dyspnea of cardiac (acute heart failure [AHF]) and pulmonary origin. We also attempted to determine the best sonographic method for the measurement of IVC diameter. Methods This prospective observational study was conducted at the intensive care unit of the emergency department of a training and research hospital. This study enrolled patients with the main symptom of dyspnea who were categorized into 2 groups, cardiac dyspnea and pulmonary dyspnea groups, based on the final diagnosis. All patients underwent sonographic measurement of minimum and maximum diameters of IVC, and the caval index (CI) was calculated in both M-mode and B-mode. The sensitivity, specificity, and likelihood ratios (LR) of the IVC values for the differentiation of the 2 groups were calculated. Results This study included a total of 74 patients with a mean age of 72.8 years. Thirty-two patients had dyspnea of cardiac origin, and 42 patients had dyspnea of pulmonary origin. The IVC diameter measured with B-mode during inspiration (B-mode i) was the most successful method for differentiation of the 2 groups. B-mode i values greater than 9 mm predicted dyspnea of cardiac origin with a sensitivity of 84.4% and a specificity of 92.9% (+ LR: 11.8, LR: 0.16). Conclusion Sonographic assessment of the IVC diameter may be used as a rapid, readily, nonexpensive, complication-free, and reproducible technique for the differentiation of cardiac and pulmonary causes of dyspnea. B-mode i measurement may be more successful in the differentiation of dyspnea compared with other IVC diameters and calculations.
