Purpose: The veno-arterial CO2 difference (Pv-aCO2) is a useful marker capable of identifying a subpopulation of shocked patients who present a cardiac output insufficient for the tissue metabolic demands. Some Authors have highlighted a linear relationship between Pv-aCO2 determined by mixed or central venous blood. This research aims to establish whether there is a linear relationship between Pv-aCO2 determined by peripheral venous blood (Pv-aCO2p) and mixed venous blood and the agreement between the two measures. Methods: Prospective, single-centre, observational clinical study on septic shocked and invasively ventilated patients during the first 24 hours from admission in ICU. Results: On 38 determinations, the Bravais-Pearson r between Pv-aCO2 and Pv-aCO2p was 0.70 (95%CI 0.48 – 0.83; p-value = 1.25 x 10^-6). The Bland-Altman test's mean bias was 4.11 mmHg (95%CI 2.82 – 5.39); the repeatability coefficient was 11.05. The differential and proportional bias were 2.81 (95%CI 0.52 – 5.11) and 1.29 (95%CI 0.86 – 1.72), respectively, through the Taffé method. Conclusion: Pv-aCO2p could be used in clinical settings wider than the ICU alone, where central venous access is not routine, to establish early the adequacy of the circulation and, more specifically, of cardiac output versus tissue metabolic demands in septic patients.

Lung ultrasound (LU) has a multitude of features and capacities that make it a useful medical tool to assist physicians contending with the pandemic spread of novel coronavirus disease-2019 (COVID-19) caused by coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Thus, an LU approach to patients with suspected COVID-19 is being implemented worldwide. In noncritical COVID-19 patients, 2 new LU signs have been described and proposed, the “waterfall” and the “light beam” signs. Both signs have been hypothesized to increase the diagnostic accuracy of LU for COVID-19 interstitial pneumonia. In critically ill patients, a distinct pattern of LU changes seems to follow the disease's progression, and this information can be used to guide decisions about when a patient needs to be ventilated, as occurs in other disease states similar to COVID-19. Furthermore, a new algorithm has been published, which enables the automatic detection of B-lines as well as quantification of the percentage of the pleural line associated with lung disease. In COVID-19 patients, a direct involvement of cardiac function has been demonstrated, and ventilator-induced diaphragm dysfunction might be present due to the prolonged mechanical ventilation often involved, as reported for similar diseases. For this reason, cardiac and diaphragm ultrasound evaluation are highly important. Last but not least, due to the thrombotic tendency of COVID-19 patients, particular attention also should be paid to vascular ultrasound. This review is primarily devoted to the study of LU in COVID-19 patients. The authors explain the significance of its “light and shadows,” bearing in mind the context in which LU is being used—the emergency department and the intensive care setting. The use of cardiac, vascular, and diaphragm ultrasound is also discussed, as a comprehensive approach to patient care.

The shortage of organs and the growing need for them over recent years have led to the adoption of less stringent donor acceptance criteria, resulting in the approval of marginal organs for transplant, especially from elderly donors. This implies a higher risk of graft dysfunction, a higher frequency of immunological and vascular complications, and shorter graft survival. Several strategies have been implemented in clinical practice to assess graft quality and suitability for transplantation. We have started to test the prospective intraoperative use of thermo-vision cameras during graft reperfusion. Images were acquired using the FLIR One Pro thermo-vision camera for android devices. We hypothesized that thermal images would give a better perspective about the quality of arterial perfusion and graft revascularization of the renal cortex. Thermo-vision cameras provide an easy-to-use, noninvasive, cost-effective tool for the global assessment of kidney graft cortical microcirculation in the immediate post-reperfusion period, providing additional data on the immediate viability and function of a graft.

Objective: To evaluate the incidence of postoperative complications arising within 30 days of minimally invasive esophagectomy in the prone position with total lung ventilation and their relationship with 30-day and 1-year mortality. Secondary outcomes included possible anesthesia-related factors linked to the development of complications. Methods: The study is a retrospective single-center observational study at the Anesthesia and Surgical Department of a tertiary care center in the northeast of Italy. Patients underwent cancer resection through esophagectomy in the prone position without one-lung ventilation. Results: We included 110 patients from January 2010 to December 2017. A total of 54% of patients developed postoperative complications that increased mortality risk at 1 year of follow-up. Complications postponed first oral intake and delayed patient discharge to home. Positive intraoperative fluid balance was related to increased mortality and the risk to develop postoperative complications. C-reactive protein at third postoperative day may help detect complication onset. Conclusions: Complication onset has a great impact on mortality after esophagectomy. Some anesthesia-related factors, mainly fluid balance, may be associated with postoperative mortality and morbidity. These factors should be carefully taken into account to obtain better outcomes after esophagectomy in the prone position without one-lung ventilation.

At the end of 2019, a novel coronavirus (COVID-19) was identified as the cause of a cluster of pneumonia cases, with high needs of mechanical ventilation in critically ill patients. It is still unclear whether different types of COVID-19 pneumonia require different ventilator strategies. With electrical impedance tomography (EIT) we evaluated, in real time and bedside, the distribution of ventilation in the different pulmonary regions before, during, and after pronation in COVID-19 respiratory failure. We present a brief literature review of EIT in non-COVID-19 patients and a report of 2 COVID-19 patients: one that did not respond well and another one that improved during and after pronation. EIT might be a useful tool to decide whether prone positioning should or should not be used in COVID-19 pneumonia.

Background Diaphragmatic dysfunction is a major factor responsible for weaning failure in patients that underwent prolonged invasive mechanical ventilation for acute severe respiratory failure from COVID-19. This study hypothesizes that ultrasound measured diaphragmatic thickening fraction (DTF) could provide corroborating information for weaning COVID-19 patients from mechanical ventilation. Methods This was an observational, pragmatic, cross-section, multicenter study in 6 Italian intensive care units. DTF was assessed in COVID-19 patients undergoing weaning from mechanical ventilation from 1st March 2020 to 30th June 2021. Primary aim was to evaluate whether DTF is a predictive factor for weaning failure. Results Fifty-seven patients were enrolled, 25 patients failed spontaneous breathing trial (44%). Median length of invasive ventilation was 14 days (IQR 7–22). Median DTF within 24 h since the start of weaning was 28% (IQR 22–39%), RASS score (− 2 vs − 2; p = 0.031); Kelly-Matthay score (2 vs 1; p = 0.002); inspiratory oxygen fraction (0.45 vs 0.40; p = 0.033). PaO2/FiO2 ratio was lower (176 vs 241; p = 0.032) and length of intensive care stay was longer (27 vs 16.5 days; p = 0.025) in patients who failed weaning. The generalized linear regression model did not select any variables that could predict weaning failure. DTF was correlated with pH (RR 1.56 × 1027; p = 0.002); Kelly-Matthay score (RR 353; p 2/FiO2 ratio (RR 1.03; p = 0.05); SAPS2 (RR 0.71; p = 0.005); hospital and ICU length of stay (RR 1.22 and 0.79, respectively; p Conclusions DTF in COVID-19 patients was not predictive of weaning failure from mechanical ventilation, and larger studies are needed to evaluate it in clinical practice further.

Purpose. Cardiac surgery is characterized by a high risk of complications related to perioperative bleeding. Guidelines suggest the use of local algorithms based on perioperative point-of-care tests to assess and manage potential coagulation abnormalities. We investigated whether heparin reversal administration affects the adenosine-5-diphosphate (ADP) test values, thus identifying the earliest time point following cardio-pulmonary bypass that permits the promptest detection and treatment of potential platelet dysfunctions. Methods. This was a retrospective, single-center, observational study enrolling cardiac surgery patients requiring cardiac bypass. ADP-tests at 4 different time-points during surgery (T0: baseline, T1: at aortic de-clamping, T2: 10 minutes after protamine administration, and T3: at the end of surgery) were performed. Results. 63 patients undergoing elective cardiac surgery were studied. Baseline ADP-test values were almost constantly greater than intraoperative values, and end of surgery values were often greater than previous intraoperative values. The only difference that proved to be not statistically significant was between T1 and T2, with a clinically insignificant mean difference of −.2 U (95%CI of difference: −6.9 - 6.5 U). There was no correlation between the variation in ADP-test values pre- and post-protamine administration and the protamine-to-heparin ratio. Conclusion. The results of the present study support the hypothesis that the ADP-test could be performed early, at aortic de-clamping before protamine administration. This approach allows for the promptest assessment of a potential impairment in platelet function, and its timely correction.

Background To produce statements based on the available evidence and an expert consensus (as members of the Lung Ultrasound Working Group of the Italian Society of Analgesia, Anesthesia, Resuscitation, and Intensive Care, SIAARTI) on the use of lung ultrasound for the management of patients with COVID-19 admitted to the intensive care unit. Methods A modified Delphi method was applied by a panel of anesthesiologists and intensive care physicians expert in the use of lung ultrasound in COVID-19 intensive critically ill patients to reach a consensus on ten clinical questions concerning the role of lung ultrasound in the following: COVID-19 diagnosis and monitoring (with and without invasive mechanical ventilation), positive end expiratory pressure titration, the use of prone position, the early diagnosis of pneumothorax- or ventilator-associated pneumonia, the process of weaning from invasive mechanical ventilation, and the need for radiologic chest imaging. Results A total of 20 statements were produced by the panel. Agreement was reached on 18 out of 20 statements (scoring 7–9; “appropriate”) in the first round of voting, while 2 statements required a second round for agreement to be reached. At the end of the two Delphi rounds, the median score for the 20 statements was 8.5 [IQR 8.9], and the agreement percentage was 100%. Conclusion The Lung Ultrasound Working Group of the Italian Society of Analgesia, Anesthesia, Resuscitation, and Intensive Care produced 20 consensus statements on the use of lung ultrasound in COVID-19 patients admitted to the ICU. This expert consensus strongly suggests integrating lung ultrasound findings in the clinical management of critically ill COVID-19 patients.

Pneumomediastinum (PNM) and pneumothorax (PNX) are documented complications of arthroscopic shoulder surgery (ATS). Plexus anesthetic block and tracheal lesions during endotracheal intubation are hypothesized to be the underlying risk factors; however, the actual evidence supporting this hypothesis is scarce.A case of bilateral laterocervical emphysema, subcutaneous edema, and signs of PNM after ATS performed under general anesthesia and supra-scapular nerve block is presented. An up-to-date systematic review of PNM/PNX during orthopedic surgery was performed, involving six databases: PubMed (1996–present), Embase (1974–present), Scopus (2004–present), SpringerLink (1950–present), Ovid Emcare (1995–present), and Google Scholar (2004–present).Twenty-five case studies met the eligibility criteria. In 24 cases, the patient underwent general anesthesia and orotracheal intubation; in 9 of these, a plexus anesthetic block was also performed. One case involved ATS under plexus anesthetic block only. In 10 cases, the diagnostic finding was PNM. In 5 cases, the diagnostic finding was associated with PNX. PNX was detected in 17 cases. In 2 cases, SE was found in the absence of any evidence of either PNM or PNX. A tracheal lesion was identified in 3 cases.Endotracheal intubation and loco-regional anesthesia are not the only predisposing risk factors at play in the pathogenesis of PNM/PNX. Rather, multi-factorial pathogenesis seems more probable, necessitating that specific attention is paid during ATS to the change in patient position on the operating bed, to any slipping of the endotracheal tube, to patient monitoring whilst under the drapes, and to the cuff pressure.

Lung ultrasound (LU) has rapidly become a tool for assessment of patients stricken by the novel coronavirus 2019 (COVID‐19). Over the past two and a half months (January, February, and first half of March 2020) we have used this modality for identification of lung involvement along with pulmonary severity in patients with suspected or documented COVID‐19 infection. Use of LU has helped us in clinical decision making and reduced the use of both chest x‐rays and computed tomography (CT).

Pneumomediastinum is a threatening complication that might occur after tight surgical closure of tracheostomy is performed. Physiopathology of this condition is based on several factors, including direct trauma to the tracheal wall caused by surgical maneuvers or insufficient closure of soft tissue layers which do not seal air leakage. In this paper we explore this phenomenon by reporting the case of one patient undergoing surgical closure of tracheostomy after two weeks, who later developed subcutaneous emphysema followed by pneumomediastinum. Physiopatology is analyzed and management strategies for this condition are suggested based on our experience.

Background: The need to determine prognostic factors that can predict a particularly severe or, conversely, the benign course of COVID-19 is particularly perceived in the Emergency Department (ED), considering the scarcity of resources for a conspicuous mass of patients. The aim of our study was to identify some predictors for 30-day mortality among some clinical, laboratory, and ultrasound variables in a COVID-19 patients population. Methods: Prospective single-center pilot study conducted in an ED of an University Hospital. A consecutive sample of confirmed COVID-19 patients with acute respiratory failure was enrolled from March 8th, to April 15th, 2020. Results: 143 patients were enrolled. Deceased patients (n = 65) were older (81 vs. 61 years, p

COVID-19 is an infection induced by the SARS-CoV-2 coronavirus, and severe forms can lead to acute respiratory distress syndrome (ARDS) requiring intensive care unit (ICU) management. Severe forms are associated with coagulation changes, mainly characterized by an increase in D-dimer and fibrinogen levels, with a higher risk of thrombosis, particularly pulmonary embolism. The impact of obesity in severe COVID-19 has also been highlighted. In this context, standard doses of low molecular weight heparin (LMWH) may be inadequate in ICU patients, with obesity, major inflammation, and hypercoagulability. We therefore urgently developed proposals on the prevention of thromboembolism and monitoring of hemostasis in hospitalized patients with COVID-19. Four levels of thromboembolic risk were defined according to the severity of COVID-19 reflected by oxygen requirement and treatment, the body mass index, and other risk factors. Monitoring of hemostasis (including fibrinogen and D-dimer levels) every 48 h is proposed. Standard doses of LMWH (e.g., enoxaparin 4000 IU/24 h SC) are proposed in case of intermediate thrombotic risk (BMI 120 kg), or unfractionated heparin (UFH) if renal insufficiency (200 IU/kg/24 h, IV), is proposed. The thrombotic risk was defined as very high in obese patients with ARDS and added risk factors for thromboembolism, and also in case of extracorporeal membrane oxygenation (ECMO), unexplained catheter thrombosis, dialysis filter thrombosis, or marked inflammatory syndrome and/or hypercoagulability (e.g., fibrinogen > 8 g/l and/or D-dimers > 3 μg/ml). In ICU patients, it is sometimes difficult to confirm a diagnosis of thrombosis, and curative anticoagulant treatment may also be discussed on a probabilistic basis. In all these situations, therapeutic doses of LMWH, or UFH in case of renal insufficiency with monitoring of anti-Xa activity, are proposed. In conclusion, intensification of heparin treatment should be considered in the context of COVID-19 on the basis of clinical and biological criteria of severity, especially in severely ill ventilated patients, for whom the diagnosis of pulmonary embolism cannot be easily confirmed.

Supplemental Digital Content is available in the text., The exact origin of intracardiac thrombi formation during orthotopic liver transplant remains unknown. The altered balance between hypercoagulability, hypocoagulation, and endothelial dysfunction associated with end-stage liver disease is thought to play a pivotal role. Venous stasis, vascular clamping, and reperfusion could also contribute to clot formation. The incidence of intracardiac thrombi formation stands at 4.2%, associated with a mortality rate of 45.5%, and to date, no consensus exists regarding the best way to treat this complication. Intraoperative transesophageal echocardiography is the only effective method for diagnosing intracardiac thrombi formation early, while point-of-care coagulation testing could guide the coagulation management potentially improving patient outcomes.

Italy adopted a law on chronic pain in March 2010, which focused on detection and management of this symptom, that affects approximately 25% of the population. The aim of this study is to analyze the interest of the Italian population in palliative care and chronic pain and to understand whether the Law 38/2010 made an impact on the internet search on chronic pain. Five research parameters were included using Google Trends (chronic pain, anti-inflammatory drugs, opioids, fibromyalgia, medical cannabis) from 2004 to 2019 using "joint point regression analysis." Comparisons of annual relative search volume (ARSV), average annual percentage change (AAPC), and temporal patterns were analyzed to assess loss or gain of interest in research of all the terms after adopting Law 38/2010; collected data were analyzed using Kruskall-Wallis test. The research trend of almost every word increased in time (AAPC > 0) with significant inflexion points after issuing law on chronic pain management in March 2010. Our results suggest the relevance of internet search engines, like "Doctor Google," to translate and share knowledge about specific conditions, diseases, and treatment alternatives, with a call to a raise in authoritative scientific voices on the topic, especially when it comes to widespread conditions like chronic pains.

We report a patient who presented with paraplegia after ascending aorta and arch replacement using the frozen elephant trunk technique. Immediate postoperatively cerebrospinal fluid drainage allowed successful reversal of spinal chord injury. Early awakening of patients following a frozen elephant technique is mandatory because it allows recognition and treatment of this complication by prompt cerebrospinal liquor drainage.

COVID-19 pandemic has rapidly spread worldwide causing a serious challenge to the global medical community. Italy was struck hard during the first wave earlier this year and several weaknesses as well as general unpreparedness of the national healthcare system were acknowledged. Learning essential lessons from the past, we realized how implementing contingency response measures, human resources and social dynamics could have changed the outcome if promptly adopted. This review translates the previous experience into strategic actions that has to be considered when developing appropriate national and regional operational plans to respond to a pandemic.

Background and aim of the work: The outbreak of the novel coronavirus (or SARS-CoV 2) has struck the healthcare system worldwide. Within few weeks hospitals had to reorganize their internal logistics and structure covering any level of care, from the Emergency Room to medical Departments. Methods: Due to the state of medical emergency, the Gynecology and Obstetrics Unit of the University Hospital in Udine developed new protocols for the usual standard of care, ensuring a safe environment for both healthcare providers and patients. Results: By a continuous update of scientific evidence, the Department was able to increase capacity as well as maintain flexibility when an unexpected high number of admissions was required. 40 COVID -19 positive patients were admitted to our Department between March and December 2020, none of them had complications and no case of cross infection between patients and medical staff were registered. Conclusion: We aimed to share our experience, which provided a notable lesson about what to expect and how to prepare a high-risk pregnancy referral center in response to a pandemic.

Ventilation during chest compressions can lead to an increase in peak inspiratory pressure. High inspiratory pressure can raise the risk of injury to the respiratory system and make it challenging to deliver the required tidal volume. The utilization of mechanical devices for chest compression has exacerbated this challenge. The aim of this narrative review was to summarize the different mechanical ventilation strategies applied during mechanical cardiopulmonary resuscitation (CPR). To this end, we searched the PubMed and BioMed Central databases from inception to January 2020, using the search terms “mechanical ventilation,” “cardiac arrest,” “cardiopulmonary resuscitation,” “mechanical cardiopulmonary resuscitation,” and their related terms. We included all studies (human clinical or animal-based research studies, as well as studies using simulation models) to explore the various ventilation settings during mechanical CPR. We identified 842 relevant articles on PubMed and 397 on BioMed Central; a total of 38 papers were judged to be specifically related to the subject of this review. Of this sample, 17 studies were conducted on animal models, 6 considered a simulated scenario, 13 were clinical studies (5 of which were retrospective), and 2 studies constituted literature review articles. The main finding arising from the assessment of these publications is that a high [Formula: see text] must be guaranteed during CPR. Low-grade evidence suggests turning off inspiratory triggering and applying PEEP ≥ 5 cm H(2)O. The analysis also revealed that many uncertainties persist regarding the ideal choice of ventilation mode, tidal volume, the ventilation rate setting, and the inspiratory:expiratory ratio. None of the current international guidelines indicate the “best” mechanical ventilation strategy to apply during mechanical CPR. We propose an operating algorithm worthy of future discussion and study. Future studies specifically addressing the topics covered in this review are required.

A patient with coronary artery fistula should be considered as high risk for intraoperative hemodynamic decompensation. In this article, we report the case of a 70-year-old man affected by a complex congenital coronary artery fistula defect. The patient underwent general anesthesia for spine surgery with permissive hypotension. The development of sudden intraoperative tachyarrhythmia with hemodynamic instability required immediate resuscitation and interruption of surgery. The claim advanced is that in patients with a coronary artery fistula permissive hypotension might be considered an option only if strictly necessary and real-time cardiac monitoring including transesophageal echocardiography is available to immediately detect and treat acute cardiac impairment.

Background A history of previous cardiac disease increases the maternal mortality risk by as much as 100%. There is no consensus on the absolute contraindications to vaginal delivery in valvular heart disease, but central regional anesthesia is traditionally considered contraindicated in patients with severe aortic stenosis. Case presentation A 29-year-old primigravid woman with severe aortic stenosis was admitted to the obstetrics department for programmed labor induction. With epidural anesthesia and mini-invasive hemodynamic monitoring labor and operative vaginal delivery were well tolerated, and hemodynamic stability was always maintained. Conclusions Epidural analgesia and oxytocin induction are possible for the labor management of parturients with severe aortic stenosis given that continuous non-invasive followed by invasive hemodynamic monitoring can be provided and given the absence of any obstetric or cardiologic contraindications and the strong will of the patient.

Introduzione Il trauma cranico (TBI – Traumatic Brain Injury) è una delle principali cause di morte e disabilità al mondo. Il danno cerebrale primario è rappresentato dal trauma, mentre il danno cerebrale secondario è l’evoluzione, limitabile, del danno primario. Esso necessita di una gestione precoce, che inizi immediatamente dopo il trauma e che preveda il raggiungimento di precisi target terapeutici correlati ad un miglior outcome. Attualmente le indicazioni per la gestione del TBI provengono dalle Linee Guida del 2008 (LG 2008), ma in questi anni la letteratura scientifica si è arricchita di molti studi che costituiscono un importante fonte di aggiornamento e miglioramento della gestione preospedaliera dei pazienti con trauma cranico. Scopo dello studio: valutare l’aderenza alle raccomandazioni delle LG 2008 e della più recente letteratura sulla gestone del TBI moderato e severo. Metodo: studio retrospettivo monocentrico. Criteri di inclusione: età > 18 anni, GCS 90% per O2 terapia, 95% per SpO2 e sAP>90mmHg, 85.5% per sAP>110mmHg

Background: During the COVID-19 pandemic, lung ultrasound (LUS) has been widely used since it can be performed at the patient’s bedside, does not produce ionizing radiation, and is sufficiently accurate. The LUS score allows for quantifying lung involvement; however, its clinical prognostic role is still controversial. Methods: A retrospective observational study on 103 COVID-19 patients with respiratory failure that were assessed with an LUS score at intensive care unit (ICU) admission and discharge in a tertiary university COVID-19 referral center. Results: The deceased patients had a higher LUS score at admission than the survivors (25.7 vs. 23.5; p-value = 0.02; cut-off value of 25; Odds Ratio (OR) 1.1; Interquartile Range (IQR) 1.0−1.2). The predictive regression model shows that the value of LUSt0 (OR 1.1; IQR 1.0–1.3), age (OR 1.1; IQR 1.0−1.2), sex (OR 0.7; IQR 0.2−3.6), and days in spontaneous breathing (OR 0.2; IQR 0.1–0.5) predict the risk of death for COVID-19 patients (Area under the Curve (AUC) 0.92). Furthermore, the surviving patients showed a significantly lower difference between LUS scores at admission and discharge (mean difference of 1.75, p-value = 0.03). Conclusion: Upon entry into the ICU, the LUS score may play a prognostic role in COVID-19 patients with ARDS. Furthermore, employing the LUS score as a monitoring tool allows for evaluating the patients with a higher probability of survival.

BACKGROUND Acute left ventricular dysfunction is a major complication of cardiac surgery and is associated with increased mortality. Meta-analyses of small trials suggest that levosimendan may result in a higher rate of survival among patients undergoing cardiac surgery. METHODS We conducted a multicenter, randomized, double-blind, placebo-controlled trial involving patients in whom perioperative hemodynamic support was indicated after cardiac surgery, according to prespecified criteria. Patients were randomly assigned to receive levosimendan (in a continuous infusion at a dose of 0.025 to 0.2 μg per kilogram of body weight per minute) or placebo, for up to 48 hours or until discharge from the intensive care unit (ICU), in addition to standard care. The primary outcome was 30-day mortality. RESULTS The trial was stopped for futility after 506 patients were enrolled. A total of 248 patients were assigned to receive levosimendan and 258 to receive placebo. There was no significant difference in 30-day mortality between the levosimendan group and the placebo group (32 patients [12.9%] and 33 patients [12.8%], respectively; absolute risk difference, 0.1 percentage points; 95% confidence interval [CI], -5.7 to 5.9; P = 0.97). There were no significant differences between the levosimendan group and the placebo group in the durations of mechanical ventilation (median, 19 hours and 21 hours, respectively; median difference, -2 hours; 95% CI, -5 to 1; P = 0.48), ICU stay (median, 72 hours and 84 hours, respectively; median difference, -12 hours; 95% CI, -21 to 2; P = 0.09), and hospital stay (median, 14 days and 14 days, respectively; median difference, 0 days; 95% CI, -1 to 2; P = 0.39). There was no significant difference between the levosimendan group and the placebo group in rates of hypotension or cardiac arrhythmias. CONCLUSIONS In patients who required perioperative hemodynamic support after cardiac surgery, low-dose levosimendan in addition to standard care did not result in lower 30-day mortality than placebo.

Background Pectus Excavatum is the most common deformation of the skeletal chest wall, and the Nuss procedure is used to correct this deformation. Residual pneumothorax is a frequent postoperative complication after thoracoscopy. Primary aim of this prospective observational study was to compare the level of agreement among readers using lung ultrasound and chest X-ray. Methods This was an inter-reader single-center prospective observational agreement study for lung ultrasound and chest X-ray. Three lung ultrasound evaluations were performed at the end of surgery in the operating room by two Consultant Anesthesiologist (A1 and A2) and by a medical student (A3). Chest X-ray was interpreted by a consultant Radiologist (R1) and a pool of 11 radiologists (collectively named R2). Cohen's kappa was used to evaluate the level of agreement between the two imaging techniques. Results Sixty-eight pediatric patients were included in the study. The overall agreement among (A = Anesthesiologist) A1, A2, A3, (R = Radiologist) R1, and R2 in assessing pneumothorax was fair (k = 0.32; 95% CI 0.21-0.40). The stratified analysis showed moderate inter-reader agreement among lung ultrasound readers A1, A2, and A3 (k 0.58; 95% CI 0.44-0.71), as opposed to the fair agreement found among chest X-ray readers R1 and R2 (k = 0.39; 95% CI 0.18-0.60). Conclusions Our results support the use of lung ultrasound to diagnose pneumothorax after Nuss procedure. We found that the inter-reader accuracy was better with ultrasound compared to X-ray at our institution.

Purpose: In patients with cutaneous graft versus host disease (GvHD) that is resistant to traditional steroid therapy, imatinib is a first-generation tyrosine kinase inhibitor that seems to be a viable option. However, its antifibrotic activity can be associated with serosal inflammation and fluid retention. Methods: We report a case of an adult patient who, after allogenic hematopoietic stem cell transplantation, developed a GvHD treated with imatinib at low dosage, followed by multiorgan failure. Clinical examination and cardiac ultrasound were unable to clearly recognize the low cardiac output state; laboratory analysis, filling pressure, and computed tomography examination clarified the correct diagnosis. Results: Low cardiac output state, secondary to pericardial effusion, is a diagnostic challenge. However, the association of four elements can help in its early recognition: increase in lactate levels and central venous pressure, associated with a low central venous saturation and a low brain natriuretic peptide level. Conclusions: Pericardial effusion with cardiac tamponade is a difficult diagnosis even with ultrasound. Lactate levels, central venous pressure plus venous saturation, and brain natriuretic peptide could help in early detection.

Background Hemostasis is the dynamic equilibrium between coagulation and fibrinolysis. During pregnancy, the balance shifts toward a hypercoagulative state; however placental abruption and abnormal placentations may lead to rapidly evolving coagulopathy characterized by the increased activation of procoagulant pathways. These processes can result in hypofibrinogenemia, with fibrinogen levels dropping to 2 g/L or less and an associated increased risk of post-partum hemorrhage. The aim of the present study was to evaluate the concordance between two methods of functional fibrinogen measurement: the Thromboelastography (TEG) method (also known as FLEV) vs. the Clauss method. Three patient groups were considered: healthy volunteers; non-pathological pregnant patients; and pregnant patients who went on to develop postpartum hemorrhage. Methods A prospective observational study. Inclusion criteria were: healthy volunteer women of childbearing age, non-pathological pregnant women at term, and pregnant hemorrhagic patients subjected to elective or urgent caesarean section (CS), with blood loss exceeding 1000 mL. Exclusion criteria were age

General practitioners often request specialist consultations to manage their patients affected by chronic pain, but in Italy wait times for the consultations are usually very long. For this reason, The Friuli Venezia Giulia region is the first Italian region to start using priority criteria for access to consultation with a pain specialist (brief within 10 days, delayed within 30 days, scheduled within 180 days).

The effects on the respiratory or hemodynamic function of drainage of pleural effusion on critically ill patients are not completely understood. First outcome was to evaluate the PiOevaluation of A-a gradient, End-Expiratory lung volume (EELV), heart rate (HR), mean arterial pressure (mAP), left ventricular end-diastolic volume (LVEDV), stroke volume (SV), cardiac output (CO), ejection fraction (EF), and E/A waves ratio (E/A). A tertiary outcome: evaluation of pneumothorax and hemothorax complications.Searches were performed on MEDLINE, EMBASE, COCHRANE LIBRARY, SCOPUS and WEB OF SCIENCE databases from inception to June 2018 (PROSPERO CRD42018105794).We included 31 studies (2265 patients). Pleural drainage improved the P/F ratio (SMD: -0.668; CI: -0.947-0.389; p .001), EELV (SMD: -0.615; CI: -1.102-0.219; p = .013), but not A-a gradient (SMD: 0.218; CI: -0.273-0.710; p = .384). HR, mAP, LVEDV, SV, CO, E/A and EF were not affected. The risks of pneumothorax (proportion: 0.008; CI: 0.002-0.014; p = .138) and hemothorax (proportion: 0.006; CI: 0.001-0.011; p = .962) were negligible.Pleural effusion drainage improves oxygenation of critically ill patients. It is a safe procedure. Further studies are needed to assess the hemodynamic effects of pleural drainage.

An "epidemic use" of legal opioids in the USA and other countries has been reported in the last 15 years. We have analysed the database of the Italian Ministry of Health regarding the prescription of opioids for pain management to verify the trend of opioids uses in Italy.The amount of opioids prescribed for every single Italian patient in 2013 was anonymously recorded and transformed in daily MED (morphine equivalent dose). We considered every monthly percentage increase of MED during the entire period of chronic therapy for each patient.Classes of dosage increase for all patients in chronic therapy, distinguished between cancer and non-cancer ones, were created. We deduce that decreases or increases of small proportions prevailed in the observation period.The opioids "plague" that is striking the USA is not registered in Italy during the observation period. The reasons might be due to the innovative and effective law 38/2010 and a health care system able to guarantee appropriate prescriptions for major analgesics.

The presence of an unknown intracardiac shunt due to a patent foramen ovale may be an unusual cause of hypoxemia. We report the case of a patient who presented persistent hypoxemia after an adequate treatment for a severe asthma attack requiring intensive care unit admission. The patient underwent a transthoracic microbubbles contrast echocardiography that showed a massive patent foramen ovale. The favorable clinical course and the absence of major signs and symptoms related to patent foramen ovale allowed a conservative approach with a follow-up program. Patent foramen ovale should be suspected in case of persistent hypoxemia after a severe asthma attack had resolved.

BACKGROUND While interscalenic nerve block (INB) is still considered the gold standard for shoulder arthroscopy, its postoperative analgesic effectiveness has recently been called into question. Meanwhile, in light of its high-quality postoperative pain relief, a renewed interest has emerged in suprascapular nerve block (SNB). The first aim of our study was to compare the postoperative analgesia effects of these two types of block at two, four and six hours after surgery. We also assessed shoulder functional recovery over a 6-month follow-up period. METHODS All patients requiring arthroscopic shoulder surgery for rotator cuff repair during the study period were enrolled. INB or SNB was performed under ultrasound guidance. The patients underwent general anaesthesia. Numerical rate scores (NRS) at rest and in motion at two, four and six postoperative hours were recorded. RESULTS Over two years, 280 patients were screened. Of these, 136 were excluded. Pain scores after surgery were lower at two hours in INB at rest (0.70±1.50 versus 2.1±2.2; P

Objective/background: Epidural analgesia improves pain control and outcomes of abdominal aortic aneurysm procedures, while the effect of thoracic epidural analgesia on thoraco-abdominal aortic aneurysm (TAAA) repair is unknown. The aim of the study was to evaluate thoracic epidural analgesia effects in patients undergoing open TAAA repair in terms of pain control and clinically relevant outcomes. Methods: This was a retrospective study of a prospectively collected database. Patients undergoing open TAAA repair between January 2009 and December 2016. Results: Four hundred and fifty-nine consecutive patients were included. Thoracic epidural analgesia was used in 409 (89%) of cases. On multivariable analysis, patients who received thoracic epidural analgesia experienced reduced post-operative pain (odds ratio [OR] 0.003, 95% confidence interval [CI] 0.0007–0.009; p
