Femoro-axillary versus femoro-femoral veno-arterial extracorporeal membrane oxygenation for refractory cardiogenic shock: A monocentric retrospective study.

RATIONALE: For veno-arterial extracorporeal membrane oxygenation (ECMO), the femoral artery is the preferred cannulation site (femoro-femoral: Vf-Af). This results in retrograde aortic flow, which increases the left ventricular afterload and can lead to severe pulmonary edema and thrombosis of the cardiac chambers. Right axillary artery cannulation (femoral-axillary: Vf-Aa) provides partial anterograde aortic flow, which may prevent some complications. This study aimed to compare the 90-day mortality and complication rates between VF-AA and VF-AF. METHODS: Consecutive adult patients with cardiogenic shock who received peripheral VA-ECMO between 2013 and 2019 at our institution were retrospectively included. The exclusion criteria were refractory cardiac arrest, multiple VA-ECMO implantations due to vascular access changes, weaning failure, or ICU readmission. A statistical approach using inverse probability of treatment weighting was used to estimate the effect of the cannulation site on the outcomes. The primary endpoint was the 90-day mortality. The secondary endpoints were vascular access complications, stroke, and other complications related to retrograde blood flow. Outcomes were estimated using logistic regression analysis. RESULTS: VA-ECMO was performed on 534 patients. Patients with refractory cardiac arrest (n = 77 (14%)) and those supported by multiple VA-ECMO (n = 92, (17%)) were excluded. Out of the 333 patients studied (n = 209 Vf-Aa; n = 124 VF-AF), the main indications for VA-ECMO implantation were post-cardiotomy (33%, n = 109), dilated cardiomyopathy (20%, n = 66), post-cardiac transplantation (15%, n = 50), acute myocardial infarction (14%, n = 46) and other etiologies (18%, n = 62). The median SOFA score was 9 [7-11], and the crude 90-day mortality rate was 53% (n = 175). After IPTW, the 90-day mortality was similar in the Vf-Aa and VF-AF groups (54% vs 58%, IPTW-OR = 0.84 [0.54-1.29]). Axillary artery cannulation was associated with significantly fewer local infections (OR = 0.21, 95% CI:0.09-0.51), limb ischemia (OR = 0.37, 95% CI:0.17-0.84), bowel ischemia (OR = 0.16, 95% CI:0.05-0.51) and pulmonary edema (OR = 0.52, 95% CI:0.29-0.92) episodes, but with a higher rate of stroke (OR = 2.87, 95% CI:1.08-7.62) than femoral artery cannulation. CONCLUSION: Compared to VF-AF, axillary cannulation was associated with similar 90-day mortality rates. The high rate of stroke associated with axillary artery cannulation requires further investigation.

Temporary ICUs during the COVID-19 pandemic first wave: description of the cohort at a French centre.

BACKGROUND: During the COVID-19 first wave in France, the capacity of intensive care unit (ICU) beds almost doubled, mainly because of the opening of temporary ICUs with staff and equipment from anaesthesia. OBJECTIVES: We aim to investigate if the initial management in temporary ICU is associated with a change in ICU mortality and short-term prognosis. DESIGN: Retrospective single-centre cohort study. SETTING: Surgical ICU of the Bichat Claude Bernard University Hospital during the COVID-19 "first wave" (from 18 March to 10 April 2020). PATIENTS: All consecutive patients older than 18 years of age with laboratory-confirmed SARS-CoV-2 infection and/or typical radiological patterns were included during their first stay in the ICU for COVID-19. INTERVENTION: Patients were admitted to a temporary ICU if no room was available in the classical ICU and if they needed invasive mechanical ventilation but no renal replacement therapy or Extracorporeal Membrane Oxygenation (ECMO) in the short term. The temporary ICUs were managed by mixed teams (from the ICU and anaesthesiology departments) following a common protocol and staff meetings. MAIN OUTCOME MEASURE: ICU mortality RESULTS: Among the 59 patients admitted, 37 (62.7%) patients had initial management in the temporary ICU. They had the same characteristics on admission and the same medical management as patients admitted to the classical ICU. ICU mortality was similar in the 2 groups (32.4% in temporary ICUs versus 40.9% in classical ICUs; p=0.58). SAPS-II and ECMO use were associated with mortality in multivariate analysis but not admission to the temporary ICU. CONCLUSION: In an overload context of the ICU of a geographical area, our temporary ICU model allowed access to intensive care for all patients requiring it without endangering them.

Characteristics and outcomes of patients undergoing anesthesia while SARS-CoV-2 infected or suspected: a multicenter register of consecutive patients.

BACKGROUND: There are limited data to detail the perioperative anesthetic management and the incidence of postoperative respiratory complications among patients requiring an anesthetic procedure while being SARS-CoV-2 positive or suspected. METHODS: An observational multicenter cohort study was performed including consecutive patients who were SARS-CoV-2 confirmed or suspected and who underwent scheduled and emergency anesthesia between March 17 and May 26, 2020. RESULTS: A total of 187 patients underwent anesthesia with SARS-CoV-2 confirmed or suspected, with ultimately 135 (72.2%) patients positive and 52 (27.8%) negative. The median SOFA score was 2 [0; 5], and the median ARISCAT score was 49 [36; 67]. The major respiratory complications rate was 48.7% (n = 91) with 40.4% (n = 21) and 51.9% (n = 70) in the SARS-CoV-2-negative and -positive groups, respectively (p = 0.21). Among both positive and negative groups, patients with a high ARISCAT risk score (> 44) had a higher risk of presenting major respiratory complications (p < 0.01 and p = 0.1, respectively). DISCUSSION: When comparing SARS-COV-2-positive and -negative patients, no significant difference was found regarding the rate of postoperative complications, while baseline characteristics strongly impact these outcomes. This finding suggests that patients should be scheduled for anesthetic procedures based on their overall risk of postoperative complication, and not just based on their SARS-CoV-2 status.

One-Year Outcome After Cardiac Surgery for Patients With Cancer: An Observational Monocentric Retrospective Study.

OBJECTIVES: Cardiac surgery increasingly is being performed in patients with a history of or with active cancer. The aim of this study was to analyze the association between a history of cancer and 1-year mortality after cardiac surgery with cardiopulmonary bypass (CPB). DESIGN: An observational monocentric study, with data collected from a prospective institutional database was conducted. SETTING: A single academic center. PARTICIPANTS: All consecutive patients undergoing cardiac surgery with CPB between 2005 and 2017. INTERVENTION: None. METHODS: A history of cancer was preoperatively identified. Mortality rates were estimated by the Kaplan-Meier method. The 1-year mortality risk of patients with and without cancer was compared using a multivariate Cox model. MEASUREMENTS AND MAIN RESULTS: During the study period, 12,143 patients underwent cardiac surgery with CPB, including 4,681 (39%) isolated coronary artery bypass surgeries. Their median EuroSCORE II was 3.1, interquartile range 1.5-to-6.4. Nine hundred thirty patients (8%) had a diagnosis of cancer, out of whom 469 (50%) were diagnosed ≤5 years before the index surgery; 103 (11%) patients had hemopathy, and 825 (89%) had solid cancers. The estimated unadjusted 1-year mortality was significantly higher among patients with cancer, 11% (95% confidence interval [CI] 10-14) versus 8% (95%CI 7-9) p < 0.01. After adjustment, a diagnosis of cancer was not associated with the risk of 1-year mortality (adjusted hazard ratio = 1.17 [95%CI 0.96-1.43]; p = 0.13). CONCLUSIONS: In a large cohort of patients undergoing cardiac surgery with CPB, cancer was not independently associated with 1-year mortality. An isolated cancer history should not lead to denial of cardiac surgery. The impact of cancer on complications and long-term survival after cardiac surgery requires further research.

The Prognostic Role of Early Postoperative Troponin I in Lung Transplantation-A Retrospective 7-Year Analysis.

OBJECTIVES: Postoperative cardiac troponin I concentration is predictive of worsened outcomes in cardiac surgery. Lung transplantation (LT) surgery shares common features with cardiac surgery, but postoperative troponin has yet to be investigated. The authors aimed to evaluate the association between early postoperative troponin concentration and the 1-year mortality after transplantation. DESIGN: A retrospective, observational, single-center study. SETTING: At a tertiary care, university hospital. PARTICIPANTS: Patients who underwent lung transplantation from January 2011 to December 2017 INTERVENTIONS: For each patient, preoperative, intraoperative, and postoperative data were collected, as well as the troponin I measurement at the moment of postoperative intensive care unit admission. MEASUREMENTS AND MAIN RESULTS: Two hundred twenty LT procedures were analyzed. Troponin I was elevated in all LT patients, with a median of 3.82 ng/mL-1 (2-6.42) ng/mL-1 significantly higher in non-survivors than in survivors with 5.39 (2.88-7.44) v 3.50 ng/mL (1.74-5.76), p = 0.005. In the multivariate analysis, the authors found that only the Simplified Acute Physiology Score II score (hazard ratio [HR] 1.03; 95% confidence interval [CI] [1.001; 1.05]; p = 0.007) and the need to maintain extracorporeal life support at the end of surgery (HR 2.54; 95% CI [1.36; 4.73]; p = 0.003) were independently associated with the 1-year mortality. The multiple linear regression model found that troponin levels were associated with the need for extracorporeal life support (ECLS) (p = 0.014), the amount of transfused packed red blood cells (p = 0.008), and bilateral LT (p < 0.001). CONCLUSION: Early postoperative troponin serum levels were not independently associated with 1-year mortality. Early postoperative troponin I levels were correlated to bilateral LT, the need for ECLS, and intraoperative blood transfusion.

Clinical reasoning in anaphylactic shock: addressing the challenges faced by anaesthesiologists in real time: A clinical review and management algorithms.

Acute hypersensitivity reactions to drugs occur infrequently during anaesthesia and the peri-operative period. When clinical presentation includes the classical triad, erythema, cardiovascular abnormalities and increased airway pressure, the diagnosis is evident and the challenge is to prescribe a therapeutic regimen according to guidelines and to manage refractory signs in a timely manner. In many situations, however, the initial clinical signs are isolated, such as increased airway pressure or arterial hypotension. Rendering a differential diagnosis with causes and mechanisms other than acute hypersensitivity reactions (AHRs) is difficult, delaying treatment with possible worsening of the clinical signs, and even death, in previously healthy individuals. In these difficult diagnostic situations, clinical reasoning is mandatory, and guidelines do not explicitly explain the elements on which clinical reasoning can be built. In this article, based on clinical evidence whenever available, experimental data and pathophysiology, we propose algorithms that have been evaluated by experts. The goal of these algorithms is to provide explicit elements on which the differential diagnosis of AHRs can be made, accelerating the implementation of adequate therapy.

Epidemiology and prognosis of anti-infective therapy in the ICU setting during acute pancreatitis: a cohort study.

BACKGROUND: Recent international guidelines for acute pancreatitis (AP) recommend limiting anti-infective therapy (AIT) to cases of suspected necrotizing AP or nosocomial extrapancreatic infection. Limited data are available concerning empirical and documented AIT prescribing practices in patients admitted to the intensive care unit (ICU) for the management of AP. METHODS: Using a multicentre, retrospective (2009-2014), observational database of ICU patients admitted for AP, our primary objective was to assess the incidence of AIT prescribing practices during the first 30 days following admission. Secondary objectives were to assess the independent impact of centre characteristics on the incidence of AIT and to identify factors associated with crude hospital mortality in a logistic regression model. RESULTS: In this cohort of 860 patients, 359 (42%) received AIT on admission. Before day 30, 340/359 (95%) AIT patients and 226/501 (45%) AIT-free patients on admission received additional AIT, mainly for intra-abdominal and lung infections. A large heterogeneity was observed between centres in terms of the incidence of infections, therapeutic management including AIT and prognosis. Administration of AIT on admission or until day 30 was not associated with an increased mortality rate. Patients receiving AIT on admission had increased rates of complications (septic shock, intra-abdominal and pulmonary infections), therapeutic (surgical, percutaneous, endoscopic) interventions and increased length of ICU stay compared to AIT-free patients. Patients receiving delayed AIT after admission and until day 30 had increased rates of complications (respiratory distress syndrome, intra-abdominal and pulmonary infections), therapeutic interventions and increased length of ICU stay compared to those receiving AIT on admission. Risk factors for hospital mortality assessed on admission were age (adjusted odds ratio [95% confidence interval] 1.03 [1.02-1.05]; p < 0.0001), Balthazar score E (2.26 [1.43-3.56]; p < 0.0001), oliguria/anuria (2.18 [1.82-4.33]; p < 0.0001), vasoactive support (2.83 [1.73-4.62]; p < 0.0001) and mechanical ventilation (1.90 [1.15-3.14]; p = 0.011), but not AIT (0.63 [0.40-1.01]; p = 0.057). CONCLUSIONS: High proportions of ICU patients admitted for AP receive AIT, both on admission and during their ICU stay. A large heterogeneity was observed between centres in terms of incidence of infections, AIT prescribing practices, therapeutic management and outcome. AIT reflects the initial severity and complications of AP, but is not a risk factor for death.

Clinical characteristics and prognosis of bacteraemia during postoperative intra-abdominal infections.

BACKGROUND: Bloodstream infections of abdominal origin are usually associated with poor prognosis. We assessed the clinical and microbiological characteristics of critically ill patients admitted to the intensive care unit (ICU) for postoperative intra-abdominal infection (PIAI) and analysed the influence of bacteraemia on their outcome. METHODS: All consecutive PIAI patients admitted to the ICU between 1999 and 2014 were prospectively analysed. Bacteraemic patients (at least one positive blood culture in the 24 h preceding/following surgery) were compared with non-bacteraemic patients. Demographic characteristics, underlying disease, severity scores at the time of reoperation, microbiological results, therapeutic management, outcome, and survival were recorded. Results are expressed as median (interquartile range (IQR)) or proportions. RESULTS: Overall, 343 patients (54% male, 62 (49-73) years old) with PIAI were analysed, including 64 (19%) bacteraemic patients. Immunosuppression and cancer were more frequent in bacteraemic patients (p < 0.001 in both cases). No difference between groups was observed for the characteristics of initial surgery. Time to reoperation, site, and cause of PIAI were similar in both groups. At the time of reoperation, Sequential Organ Failure Assessment (SOFA) score was higher in bacteraemic patients (8 (6-10) versus 7 (4-10); p < 0.05). A predominance of Gram-positive (34%) and Gram-negative (47%) bacteria were recovered from blood cultures (polymicrobial bacteraemia in 9 (14%) patients and bacteraemia involving multidrug-resistant organisms in 14 (22%) patients). In multivariate analysis, risk factors for bacteraemia were immunosuppression or cancer, high SOFA score, and E. coli in peritoneal samples. Bacteraemia did not impact the management (with similar results for the adequacy of antibiotic therapy, anti-infective agents used, de-escalation or duration of therapy in both groups). Neither hospital mortality nor morbidity criteria differed between groups. Risk factors for mortality in multivariate analysis were urgent initial surgery, high Simplified Acute Physiology Score (SAPS) II score and documented antifungal therapy, but not perioperative bacteraemia. CONCLUSIONS: In this ICU population, bacteraemia did not change the overall management of patients with PIAI. Our data suggest that bacteraemic patients do not require a specific management.

Efficacy and tolerance of dolutegravir-based combined ART in perinatally HIV-1-infected adolescents: a French multicentre retrospective study.

Objectives: To assess the safety and efficacy of a dolutegravir-based regimen in perinatally HIV-1-infected adolescents. Patients and methods: We conducted a retrospective multicentre study of 50 adolescents beginning dolutegravir-based treatment regimens between January 2014 and December 2015. Clinical and biological data collected before and after dolutegravir initiation were analysed. The primary endpoint was the proportion of patients achieving a plasma viral load (PVL) <50 copies/mL within 3 months of dolutegravir initiation (for patients with detectable viraemia at baseline) and maintaining virological suppression (PVL <50 copies/mL) until the last follow-up visit (for all patients). Results: Virological suppression was noted for 17/50 adolescents at baseline. Dolutegravir-based regimens maintained virological success in 14/17 patients (82%). The other three patients experienced a transient viral rebound, before PVL fell to < 50 copies/mL again, with no need to change the antiretroviral regimen. Thirty-three viraemic adolescents were enrolled. All but one had already received antiretroviral drugs. Virological success was achieved and maintained in 19/33 subjects (58%). Another three adolescents with initial virological failure had an undetectable PVL at the end of follow-up, with reinforced measures to improve compliance. Overall, sustained virological success was observed in 66% of patients and 78% of patients had an undetectable PVL at the last visit. Dolutegravir was well tolerated. Only one patient stopped treatment for severe drug-related adverse effects (dizziness and sleep disturbance). No emergence of resistance mutations was observed in patients with virological failure. Conclusions: Dolutegravir was safe and virologically effective in these patients, for whom multiple interventions were required to improve compliance.

Socioeconomic Deprivation and Utilization of Anesthetic Care During Pregnancy and Delivery: A Secondary Analysis of a French Prospective, Multicenter, Cohort Study.

BACKGROUND: Socioeconomic deprivation is associated with reduced use of antenatal resources and poor maternal outcomes with pregnancy. Research examining the association between socioeconomic deprivation and use of obstetric anesthesia care in a country providing universal health coverage is scarce. We hypothesized that in a country providing universal health coverage, France, socioeconomic deprivation is not associated with reduced use of anesthetic care during pregnancy and delivery. This study aimed to examine the association between socioeconomic deprivation and (1) completion of a mandatory preanesthetic evaluation during pregnancy and (2) use of neuraxial analgesia during labor. METHODS: Data were from a cohort of 10,419 women who delivered between 2010 and 2011 in 4 public teaching hospitals in Paris. We used a deprivation index that included 4 criteria: social isolation, poor housing condition, no work-related household income, and state-funded health care insurance. Socioeconomic deprivation was defined as a deprivation index greater than 1. Preanesthetic evaluation was considered completed if performed more than 48 hours before delivery. The association between socioeconomic deprivation and completion of the preanesthetic evaluation and use of neuraxial labor analgesia was assessed by multivariable logistic regression adjusting for education level, country of birth, and maternal and pregnancy characteristics. RESULTS: Preanesthetic evaluation was completed for 8142 of the 8624 women (94.4%) analyzed and neuraxial labor analgesia was used by 6258 of the 6834 women analyzed (91.6%). After adjustment, socioeconomic deprivation was associated with reduced probability of completed preanesthetic evaluation (adjusted odds ratio 0.88 [95% confidence interval, 0.79-0.98]; P = .027) but not use of neuraxial labor analgesia (adjusted odds ratio 0.97 [95% confidence interval, 0.87-1.07]; P = .540). CONCLUSIONS: In a country providing universal health care coverage, women who were socioeconomically deprived showed reduced completion of preanesthetic evaluation during pregnancy but not reduced use of neuraxial labor analgesia. Interventions should be targeted to socioeconomically deprived women to increase the completion of the preanesthetic evaluation.

Pain assessment in the postanaesthesia care unit using pupillometry: A cross-sectional study after standard anaesthetic care.

BACKGROUND: Patients assess their own pain with a numerical rating scale (NRS). In the postanaesthesia care unit (PACU), NRS helps to determine and monitor analgesic administration, but is useless in patients who are unable to communicate. In non-PACU patients, acute pain increases pupillary diameter and pupillary light reflex amplitude (PLRA), the difference between pupillary diameter before and after light stimulation. OBJECTIVES: To study the association between postoperative pain (NRS) and pupillary diameter or PLRA in PACU patients after routine anaesthetic care. DESIGN: Cross-sectional cohort study. SETTING: Bichat-Claude Bernard Hospital, Paris. PATIENTS: One hundred and forty-five patients undergoing planned surgery under general anaesthesia. INTERVENTIONS: NRS, pupillary diameter and PLRA were measured on arrival in the PACU. When NRS was more than 4, intravenous morphine titration was started and a second measurement performed. MAIN OUTCOME MEASURES: Association between NRS and pupillary diameter or PLRA was assessed with Pearson correlation coefficient (r) as was association between changes in these variables after morphine titration. RESULTS: Mean NRS was 4.7, and was more than 4 in 79 patients (55%). No statistically significant association was observed between NRS and pupillary diameter (r = 0.10, P = 0.54) or PLRA (r = 0.03, P = 0.72). Twenty-seven patients (19%) received morphine titration with significant decreases in NRS, pupillary diameter and PLRA afterwards. No association was observed between NRS changes and pupillary diameter or PLRA changes. CONCLUSION: Acute postoperative pain is not associated with pupillary diameter or PLRA. Further research is required to develop tools to assess pain in the PACU.

Challenges in the Monitoring of Therapeutic Plasma Exchange during Acute Heparin-Induced Thrombocytopenia in Adults under ECMO.

Therapeutic plasma exchange (TPE) has been proposed to remove heparin-induced thrombocytopenia (HIT) antibodies before planned thoracic surgery in patients with acute HIT and to allow brief re-exposure to heparin during surgery. In patients on extracorporeal membrane oxygenation (ECMO), simultaneous administration of TPE and alternative nonheparin anticoagulant therapies is challenging. We report 2 patients on ECMO with acute HIT who underwent repeated TPE to enable cardiothoracic surgery with the use of heparin. In both cases, serial monitoring of HIT antibody titer and heparin-induced platelet activation assay (HIPA) was performed. The effect of adding exogenous platelet factor 4 (PF4) in the HIPA was also tested. Negative anti-PF4/H IgG levels were achieved after 5 and 3 TPE sessions, respectively and patients could beneficiate from surgery with brief heparin re-exposure without any thrombotic complication. Negative HIPA results were obtained before negative anti-PF4/H IgG in one patient but remained positive in the other despite very low antibody titers. The addition of PF4 in HIPA led to more contrasted results for the two patients. Serial HIT screening including immunological and functional assays is necessary to closely monitor TPE in acute HIT patients on ECMO who require surgery. The addition of PF4 in HIPA could help detect clinically relevant platelet-activating antibodies and guide re-exposure to heparin.

Microbiological profile of patients treated for postoperative peritonitis: temporal trends 1999-2019.

BACKGROUND: Temporal changes in the microbiological resistance profile have been reported in several life-threatening infections. However, no data have ever assessed this issue in postoperative peritonitis (POP). Our purpose was to assess the rate of multidrug-resistant organisms (MDROs) in POP over a two-decade period and to analyse their influence on the adequacy of empirical antibiotic therapy (EAT). METHODS: This retrospective monocentric analysis (1999-2019) addressed the changes over time in microbiologic data, including the emergence of MDROs and the adequacy of EAT for all intensive care unit adult patients treated for POP. The in vitro activities of 10 antibiotics were assessed to determine the most adequate EAT in the largest number of cases among 17 antibiotic regimens in patients with/without MDRO isolates. Our primary endpoint was to determine the frequency of MDRO and their temporal changes. Our second endpoint assessed the impact of MDROs on the adequacy of EAT per patient and their temporal changes based on susceptibility testing. In this analysis, the subgroup of patients with MDRO was compared with the subgroup of patients free of MDRO. RESULTS: A total of 1,318 microorganisms were cultured from 422 patients, including 188 (45%) patients harbouring MDROs. The growing proportions of MDR Enterobacterales were observed over time (p = 0.016), including ESBL-producing strains (p = 0.0013), mainly related to Klebsiella spp (p < 0.001). Adequacy of EAT was achieved in 305 (73%) patients. Decreased adequacy rates were observed when MDROs were cultured [p = 0.0001 vs. MDRO-free patients]. Over the study period, decreased adequacy rates were reported for patients receiving piperacillin/tazobactam in monotherapy or combined with vancomycin and imipenem/cilastatin combined with vancomycin (p < 0.01 in the three cases). In patients with MDROs, the combination of imipenem/cilastatin + vancomycin + amikacin or ciprofloxacin reached the highest adequacy rates (95% and 91%, respectively) and remained unchanged over time. CONCLUSIONS: We observed high proportions of MDRO in patients treated for POP associated with increasing proportions of MDR Enterobacterales over time. High adequacy rates were only achieved in antibiotic combinations involving carbapenems and vancomycin, while piperacillin/tazobactam is no longer a drug of choice for EAT in POP in infections involving MDRO.

Clinical assessment of scannographic markers for sarcopenia in lung transplant candidates.

INTRODUCTION: The selection of patients for lung transplantation is difficult. An aspect of the patient's general condition and frailty can be assessed by measuring the surface area of certain muscles on CT. Indeed, sarcopenia, assessed by measuring the area of psoas muscles on scannographic sections has already been shown to be associated with poor outcomes in lung transplant and other major surgeries and could thus be helpful to evaluate candidates to lung transplant. However, it is not routinely performed by radiologists. As a pilot study, we compared the reliability of computerized tomography scan assessment for sarcopenia by clinicians with that of radiologists. MATERIALS AND METHODS: We conducted a retrospective single-centre study in which preoperative abdominal CT scans of lung transplant patients from 2014 to 2018 were analysed to assess sarcopenia by measuring the surface areas (mm2) of the psoas, paraspinal muscles at the L4 vertebra and diaphragm pillars at the celiac trunk bilaterally. The surfaces were blindly assessed by clinicians and radiologists and the intraclass correlation coefficients between the two measurements were estimated by a generalized linear model using SAS 9.4 software. RESULTS: We performed a double reading of 200 scans. The clinicians 'measurements were comparable to those of the radiologists for the psoas and paraspinal muscles but not for the diaphragm pillars. CONCLUSION: CT measurement of psoas and paraspinal muscle areas by clinicians appears reliable and feasible in routine practice and could be used in the evaluation of lung transplant candidates.

Venoarterial Extracorporeal Membrane Oxygenation as Supportive Therapy After Cardiac Arrest After Amniotic Fluid Embolism: A Case Report.

Amniotic fluid embolism is a rare but dreaded complication of pregnancy, with an incidence between 2 and 7/100,000 deliveries. We report an amniotic fluid embolism after urgent cesarean delivery diagnosed on a cardiac arrest, complicated by cardiogenic shock and acute respiratory distress syndrome. This report describes the indication, efficacy, and success of venoarterial extracorporeal membrane oxygenation in the early management of cardiac arrest, cardiac failure driven by amniotic fluid embolism, and acute respiratory distress syndrome. The use of venoarterial extracorporeal membrane oxygenation support after recovery from cardiac arrest after amniotic fluid embolism should be considered early during the management of these cases.
