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.

The objective of this study was to determine if propofol administration to veno-venous (VV) extracorporeal membrane oxygenation (ECMO) patients was associated with more incidents of oxygenator failure when compared to patients who did not receive propofol. This was a single center, retrospective cohort study. The primary outcome of the study is oxygenator exchanges per ECMO day in patients who received propofol versus those who did not receive propofol. Patients were 18 years or older on VV-ECMO support between January 1, 2015 and January 31, 2018. Patients were excluded if they required ECMO support for less than 48 h or greater than 21 days. There were five patients in the propofol arm that required oxygenator exchanges and seven patients in the control arm. The total number of oxygenator exchanges per ECMO day was not significantly different between groups ( p = 0.50). When comparing those who required an oxygenator exchange and those who did not, there was no difference in the cumulative dose of propofol received per ECMO hour (0.64 mg/kg/h vs 0.96 mg/kg/h; p = 0.16). Propofol use in patients on VV-ECMO does not appear to increase the number of oxygenator exchanges.

Background: Respiratory failure (RF) is a common cause of death and morbid complication in trauma patients. Extracorporeal membrane oxygenation (ECMO) is increasingly used in adults with RF refractory to invasive mechanical ventilation. However, use of ECMO remains limited for this patient population as they often have contraindications for anticoagulation. Study design: Medical records were retroactively searched for all adult patients who were admitted to the trauma service and received veno-venous ECMO (VV ECMO) support between June 2015 and August 2018. Survival to discharge and ECMO-related complications were collected and analyzed. Results: Fifteen patients from a large Level I trauma center met the criteria. The median PaO2/FiO2 ratio was 53.0 (IQR, 27.0–76.0), median injury severity score was 34.0 (IQR, 27.0–43.0), and the median duration of ECMO support was 11 days (IQR, 7.5–20.0). For this cohort, the survival-to-discharge rate was 87% (13/15). The incidence of neurologic complications was 13%, and deep vein thrombosis was reported in two cases (13%). Conclusions: Survival rates of trauma patients in this study are equivalent to, or may exceed, those of non-trauma patients who receive ECMO support for other types of RF. With the employment of a multidisciplinary team assessment and proper patient selection, early cannulation, traumatic RF may be safely supported with VV ECMO in experienced centers.

Abstract Background Systemic rheumatic diseases (SRDs) are a group of inflammatory disorders that can require intensive care unit (ICU) admission because of multiorgan involvement with end-organ failure(s). Critically ill SRD patients requiring extracorporeal membrane oxygenation (ECMO) were studied to gain insight into their characteristics and outcomes. Methods This French monocenter, retrospective study included all SRD patients requiring venovenous (VV)- or venoarterial (VA)-ECMO admitted to a 26-bed ECMO-dedicated ICU from January 2006 to February 2020. The primary endpoint was in-hospital mortality. Results Ninety patients (male/female ratio: 0.5; mean age at admission: 41.6 ± 15.2 years) admitted to the ICU received VA/VV-ECMO, respectively, for an SRD-related flare (n = 69, n = 38/31) or infection (n = 21, n = 10/11). SRD was diagnosed in-ICU for 31 (34.4%) patients. In-ICU and in-hospital mortality rates were 48.9 and 51.1%, respectively. Nine patients were bridged to cardiac (n = 5) or lung transplantation (n = 4), or left ventricular assist device (n = 2). The Cox multivariable model retained the following independent predictors of in-hospital mortality: in-ICU SRD diagnosis, day-0 Simplified Acute Physiology Score (SAPS) II score ≥ 70 and arterial lactate ≥ 7.5 mmol/L for VA-ECMO–treated patients; diagnosis other than vasculitis, day-0 SAPS II score ≥ 70, ventilator-associated pneumonia and arterial lactate ≥ 7.5 mmol/L for VV-ECMO–treated patients. Conclusions ECMO support is a relevant rescue technique for critically ill SRD patients, with 49% survival at hospital discharge. Vasculitis was independently associated with favorable outcomes of VV-ECMO–treated patients. Further studies are needed to specify the role of ECMO for SRD patients.

Extracorporeal membrane oxygenation (ECMO) can be delivered in veno-arterial (VA) and veno-venous (VV) configurations based on the cannulation strategy. VA and VV ECMO are delivered primarily for haemodynamic and respiratory support in patients with severe heart and lung failure, respectively. The Fick principle describes the relationship between blood flow and oxygen consumption – key parameters in the physiological management of extracorporeal support. This review will discuss the application of the Fick principle in: (i) recirculation in VV ECMO; (ii) the quantification of oxygen delivery (DO2) in VV ECMO and (iii) the quantification of transpulmonary blood flow and systemic arterial oxygen saturation in VA ECMO.

Objective We aimed to examine the risk factors and prognosis of nosocomial pneumonia (NP) during extracorporeal membrane oxygenation (ECMO). Methods We retrospectively analyzed data of patients who received ECMO at the Affiliated Hangzhou Hospital of Nanjing Medical University between January 2013 and August 2019. The primary outcome was the survival-to-discharge rate. Results Sixty-nine patients who received ECMO were enrolled, median age 42 years and 26 (37.7%) women; 14 (20.3%) patients developed NP. The NP incidence was 24.7/1000 ECMO days. Patients with NP had a higher proportion receiving veno-venous (VV) ECMO (50% vs. 7.3%); longer ECMO support duration (276 vs. 140 hours), longer ventilator support duration before ECMO weaning (14.5 vs. 6 days), lower ECMO weaning success rate (50.0% vs. 81.8%), and lower survival-to-discharge rate (28.6% vs. 72.7%) than patients without NP. Multivariable analysis showed independent risk factors that predicted NP during ECMO were ventilator support duration before ECMO weaning (odds ratio [OR] = 1.288; 95% confidence interval [CI]: 1.111–1.494) and VV ECMO mode (OR = 10.970; 95% CI: 1.758–68.467). Conclusion NP during ECMO was associated with ventilator support duration before ECMO weaning and VV ECMO mode. Clinicians should shorten the respiratory support duration for patients undergoing ECMO to prevent NP.

A 28-year-old man presented in extremis after a motorcycle crash. Following traumatic pneumonectomy, he developed right heart failure and was placed on veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) only to transition to veno-arteriovenous (VAV) ECMO due to persistent hypoxemia. Resulting flow limitation caused distal ischemia of his left leg, requiring thrombectomy and fasciotomy. Potential loss of limb necessitated transitioning to veno-venous (VV) ECMO from which he was successfully decannulated thereafter. ECMO can bridge recovery following the most dire injuries, and hybrid strategies can ameliorate post-operative complications; however, ECMO itself carries significant risks that must be weighed against intended benefit.
