AbstractImpaired skeletal muscle quality is a major risk factor for adverse outcomes in acute respiratory failure. However, conventional methods for skeletal muscle assessment are inapplicable in the critical care setting. This study aimed to determine the prognostic value of computed tomography (CT) fatty muscle fraction (FMF) as a biomarker of muscle quality in patients undergoing extracorporeal membrane oxygenation (ECMO). To calculate FMF, paraspinal skeletal muscle area was obtained from clinical CT and separated into areas of fatty and lean muscle based on densitometric thresholds. The cohort was binarized according to median FMF. Patients with high FMF displayed significantly increased 1-year mortality (72.7% versus 55.8%, P = 0.036) on Kaplan–Meier analysis. A multivariable logistic regression model was built to test the impact of FMF on outcome. FMF was identified as a significant predictor of 1-year mortality (hazard ratio per percent FMF, 1.017 [95% confidence interval, 1.002–1.033]; P = 0.031), independent of anthropometric characteristics, Charlson Comorbidity Index, Simplified Acute Physiology Score, Respiratory Extracorporeal Membrane Oxygenation Survival Prediction Score, and duration of ECMO support. To conclude, FMF predicted 1-year mortality independently of established clinical prognosticators in ECMO patients and may have the potential to become a new muscle quality imaging biomarker, which is available from clinical CT.

Abstract Background The use of extracorporeal membrane oxygenation (ECMO) in critically ill adults is increasing. There are currently no guidelines for antimicrobial prophylaxis. We analyzed 7 years of prophylactic antimicrobial use across three time series for patients on ECMO at our institution in the development, improvement, and streamlining of our ECMO antimicrobial prophylaxis protocol. Study design and Methods In this quasi-experimental interrupted time series analysis, we evaluated the impact of an initial ECMO antimicrobial prophylaxis protocol, implemented in 2014, on antimicrobial use and NHSN reportable infection rates. Then, following a revision and streamlining of the protocol in November 2018, we re-evaluated the same metrics. Results Our study population included 338 ICU patients who received ECMO between July 2011 and November 2019. After implementation of the first version of the protocol we did not observe significant changes in antimicrobial use or infection rates in these patients; however, following revision and streamlining of the protocol, we demonstrated a significant reduction in broad spectrum antimicrobial use for prophylaxis in patients on ECMO without any evidence of a compensatory increase in infection rates. Conclusion Our final protocol significantly reduces broad spectrum antimicrobial use for prophylaxis in patients on ECMO. We propose a standard antimicrobial prophylaxis regimen for patients on ECMO based on current evidence and our experience.

Abstract Introduction There is limited data on the impact of extracorporeal membrane oxygenation (ECMO) on pulmonary physiology and imaging in adult patients. The current study sought to evaluate the serial changes in oxygenation and pulmonary opacities after ECMO initiation. Methods Records of patients started on veno-venous, or veno-arterial ECMO were reviewed (n=33; mean (SD): age 50(16) years; Male: Female 20:13). Clinical and laboratory variables before and after ECMO, including daily PaO2 to FiO2 ratio (PFR), were recorded. Daily chest radiographs (CXR) were prospectively appraised in a blinded fashion and scored for the extent and severity of opacities using an objective scoring system. Results ECMO was associated with impaired oxygenation as reflected by the drop in median PFR from 101 (interquartile range, IQR: 63-151) at the initiation of ECMO to a post-ECMO trough of 74 (IQR: 56-98) on post-ECMO day 5. However, the difference was not statistically significant. The appraisal of daily CXR revealed progressively worsening opacities, as reflected by a significant increase in the opacity score (Wilk’s Lambda statistic 7.59, p=0.001). During the post-ECMO period, a >10% increase in the opacity score was recorded in 93.9% of patients. There was a negative association between PFR and opacity scores, with an average one-unit decrease in the PFR corresponding to a +0.010 increase in the opacity score (95% confidence interval: 0.002 to 0.019, p-value=0.0162). The median opacity score on each day after ECMO initiation remained significantly higher than the pre-ECMO score. The most significant increase in the opacity score (9, IQR: -8 to 16) was noted on radiographs between pre-ECMO and forty-eight hours post-ECMO. The severity of deteriorating oxygenation or pulmonary opacities was not associated with hospital survival. Conclusions The use of ECMO is associated with an increase in bilateral opacities and a deterioration in oxygenation that starts early and peaks around 48 hours after ECMO initiation.

Abstract Background Published data about bleeding management on extracorporeal membrane oxygenation (ECMO) in children is sparse and to date no global transfusion algorithm has been established. Viscoelastic testing can be effective for determining the etiology and management of coagulopathic bleeding during cardiothoracic procedures, but data regarding its usefulness in ECMO patients are scarce. Recently, low factor XIII levels were determined to be a frequent finding in adult ECMO patients(Kalbhenn et al; Perfusion 2015;30:675-82). Methods This is a retrospective analysis of thromboelastometry (ROTEM®) and factor XIII data obtained in children (ages 0 to 18 years) undergoing ECMO since 2013 in a single center children's hospital. Acute bleeding treatment was based on daily ROTEM testing, complete blood count and routine plasmatic coagulation testing. The transfusion algorithm targeted a hemoglobin level >13g dL-1, a Quick's value >50%, a plasma fibrinogen level >1.5g L-1, and a platelet count of >100,000 µL-1. Red blood cells (RBC), solvent detergent (S/D) plasma and platelet apheresis concentrates were exclusively used to maintain hemostasis. Measurement of FXIII levels is not part of routine testing, but was assessed when unexplained bleeding was observed. Results Laboratory and transfusion data from sixteen patients, age 4 (1-15) months [median(IQR)] with a body weight of 6 (3-8) kg were included. Median time on ECMO was 7 (4-9) days. Large volumes of allogeneic blood were transfused to all children, meeting criteria for massive transfusion each individual day on ECMO (Tab.1). Overall, median daily ROTEM measurements were within reference ranges (Tab.2), while median levels of FXIII were decreased despite massive transfusion [FXIII levels 42% (28-51%)]. Conclusion Pediatric ECMO was almost always combined with daily massive transfusion, which led to correction of overall ROTEM values. Notably, despite transfusion of large amounts of plasma, decreased FXIII levels were noted. This finding is supported by results of a study in adult ECMO patients, where FXIII levels <50% were observed in 88% of all patients. Although inherited homozygous FXIII deficiency is usually defined by levels <5%, even mildly to moderately reduced FXIII levels have been reported to contribute to increased bleeding after cardiac surgery(Ternström et al; Thromb Res 2010;126:e128-33). Further studies should be performed to assess the impact of FXIII substitution in pediatric ECMO patients and to investigate whether substitution of FXIII may decrease bleeding without increasing thrombotic complications.

Background Although bridge to lung transplantation (BTT) with extracorporeal membrane oxygenation (ECMO) is increasingly performed, the impact of BTT and its duration on post-transplant outcomes are unclear. Methods We retrospectively reviewed medical records of adult patients who underwent lung or heart-lung transplantation in our institution between January 2008 and December 2018. Data were compared in patients who did (n = 41; BTT) and did not (n = 36; non-BTT) require pre-transplant ECMO support. Data were also compared in patients who underwent short-term (<14 days; n = 21; ST-BTT) and long-term (≥14 days; n = 20; LT-BTT) BTTs. Results Among 77 patients included, 51 (66.2%) were male and median age was 53 years. The median bridging time in the BTT group was 13 days (interquartile range [IQR], 7–19 days). Although simplified acute physiologic score II was significantly higher in the BTT group (median, 35; IQR, 31–49 in BTT group vs. median, 12; IQR, 7–19 in non-BTT group; p<0.001), 1-year (73.2% vs. 80.6%; p = 0.361) and 5-year (61.5% vs. 61.5%; p = 0.765) post-transplant survival rates were comparable in both groups. Comparison of ST- and LT-BTT subgroups showed that 1-year (90.5% vs. 55.0%; p = 0.009) and 5-year (73.0% vs. 48.1%; p = 0.030) post-transplant survival rates were significantly higher in ST-BTT group. In age and sex adjusted model, the LT-BTT was an independent risk factor for 1-year post-transplant mortality (hazard ratio, 3.019; 95% confidence interval, 1.119–8.146; p = 0.029), whereas the ST-BTT was not. Conclusions Despite the severe illness, the BTT group showed favorable post-transplantation outcomes, particularly those bridged for less than 14 days.
