Introduction Acute respiratory distress syndrome in the context of severe sepsis and septic shock represents a serious clinical disorder. A recent case series in patients with septic shock and renal failure receiving hemoadsorption treatment showed rapid hemodynamic stabilization and increased survival, particularly in pneumonia patients and in those where therapy was started early. We hypothesized that patients suffering from pneumonia and refractory acute respiratory distress syndrome to the extent that they required extracorporeal membrane oxygenation support could possibly demonstrate the most pronounced benefit from the treatment. Methods We assessed the association of hemoadsorption treatment with hemodynamics, ventilation, and outcome variables in a set of patients with septic shock, acute respiratory distress syndrome, need for veno-venous extracorporeal membrane oxygenation, and continuous renal replacement therapy. Results Key observations include a significant stabilization in hemodynamics as evidenced by a marked decrease in catecholamine need, which was paralleled by a clear reduction in hyperlactatemia. Respiratory variables improved significantly. In addition, severity of illness and overall organ dysfunction showed a considerable decrease during the course of treatment. Observed mortality was approximately half as predicted by APACHE II. Treatment with CytoSorb was safe and well tolerated with no device-related adverse events. Discussion This is the first case series reporting on outcome variables associated to CytoSorb therapy in critically ill patients with septic shock, acute respiratory distress syndrome, veno-venous extracorporeal membrane oxygenation, and continuous renal replacement therapy. Based on our observations in this small case series, CytoSorb might represent a potentially promising therapy option for patients with refractory extracorporeal membrane oxygenation-dependent acute respiratory distress syndrome in the context of septic shock.

Purpose: We describe an approach for anticoagulation and transfusions in veno-venous–extracorporeal membrane oxygenation (VV-ECMO), evaluating factors associated with higher transfusion requirements, and their impact on mortality. Methods: Observational study on consecutive adults supported with VV-ECMO for acute respiratory distress syndrome (ARDS). We targeted an activated partial thromboplastin time of 40 to 50 seconds and a hematocrit of 24% to 30%. Univariate and multiple analyses were done to evaluate factors associated with transfusion requirements and the influence of increasing transfusions on mortality during ECMO. Results: In a cohort of 82 VV-ECMO patients (PRedicting dEath for SEvere ARDS on VV-ECMO [PRESERVE] score: 4, Interquartile range [IQR]: 3-5, Respiratory Extracorporeal Membrane Oxygenation Survival Prediction [RESP] score: 2, IQR: 2-4), 76 (92.7%) patients received at least 1 unit of packed red blood cells (PRBCs) during the intensive care unit stay related to ECMO (median PRBC/d 156 mL, IQR: 93-218; median ECMO duration 14 days, IQR: 8-22). A higher requirement of PRBC transfusions was associated with pre-ECMO hematocrit, and with the following conditions during ECMO: platelet nadir, antithrombin III (ATIII), and stage 3 of acute kidney injury (all P < .05). Sixty-two (75.6%) patients survived ECMO. Pre-ECMO hospital stay, PRBC transfusion, and septic shock were associated with mortality (all P < .05). The adjusted odds ratio for each 100mL/d increase in PRBC transfusion was 1.9 (95% confidence interval [CI]: 1.1-3.2, P = .01); for the development of septic shock it was 15.4 (95% CI: 1.7-136.8, P = .01), and for each day of pre-ECMO stay it was 1.1 (95% CI: 1-1.2, P = .04). Conclusion: Implementation of a comprehensive protocol for anticoagulation and transfusions in VV-ECMO for ARDS resulted in a low PRBC requirement, and an ECMO survival comparable to data in the literature. Lower ATIII emerged as a factor associated with increased need for transfusions. Higher PRBC transfusions were associated with ECMO mortality. Further investigations are needed to better understand the right level of anticoagulation in ECMO, and the factors to take into account in order to manage personalized transfusion practice in this select setting.

Background Case series have reported favorable outcomes with extracorporeal membrane oxygenation (ECMO) in patients with severe acute respiratory distress syndrome. However, those patients were generally young, with few comorbid conditions. Objective To characterize the clinical features and survival rates of patients with severe acute respiratory distress syndrome who met criteria for ECMO but were managed without it. Methods Patients who met the study criteria were identified prospectively. Inclusion criteria for ECMO included severe hypoxemia, uncompensated hypercapnia, or elevated end-inspiratory plateau pressures despite low tidal volume ventilation. Predicted survival rates with ECMO were calculated using the Respiratory ECMO Survival Prediction score. Results Of the 46 patients who met the criteria for severe acute respiratory distress syndrome and ECMO consideration, 5 received ECMO and 16 patients had at least 1 contraindication to it. The remaining 25 patients met ECMO criteria but did not receive the treatment. The patients’ mean age was 53.5 (SD, 14.3) years; 84% had at least 1 major comorbid condition. The median predicted survival rate with ECMO was 57%. The actual hospital discharge survival rate without ECMO was 56%. Conclusions The general medical intensive care patient population with severe acute respiratory distress syndrome is older and sicker than patients reported in prior case series in which patients were treated with ECMO. In this study, the survival rate without ECMO was similar to predicted survival rates with ECMO.

Abstract Background Acute respiratory distress syndrome (ARDS) has a reported incidence of 34–43% in ventilated burn patients and is associated with a mortality of 59% in the severe form. The use and experience with extracorporeal membrane oxygenation (ECMO) in burn patients developing ARDS are still limited. We present our results and discuss the significance of ECMO in treating burn patients. Methods A retrospective analysis of burn patients treated with ECMO for ARDS between January 2017 and January 2019 was performed. Demographic, clinical, and outcome data were collected and analyzed. Results Eight burn patients were treated at our institution with ECMO in the designated time period. Of these, all but one patient had inhalation injury, burn percentage of TBSA was 37 ± 23%, ABSI score was 8.4 ± 2, and R-Baux-score was 98 ± 21. Seven patients developed severe ARDS and one patient moderate ARDS according to the Berlin classification with a PaO2/FiO2 ratio upon initiation of ECMO therapy of 62 ± 22 mmHg. ECMO duration was 388 ± 283 h. Three patients died from severe sepsis while five patients survived to hospital discharge. Conclusions ECMO is a viable therapy option in burn patients developing severe ARDS and can contribute to survival rates similar to ECMO therapy in non-burn-associated severe ARDS. Consequently, patients with severe respiratory insufficiency with unsuccessful conventional treatment and suspected worsening should be transferred to burn units with the possibility of ECMO treatment to improve outcome.
