Introducing ECMO/ECLS in sub-Saharan Africa – prospects and perspectives

Background: The introduction of modern medical technologies reduced mortality in adults and increased survival in infants less than five years old. Cardiac and respiratory failure can be managed through mechanical circulatory support devices such as ECMO/ECLS (Extracorporeal Membrane Oxygenation/ Extracorporeal Life Support).Main Findings: We evaluate the importance and potential impact of using ECMO/ECLS in improving health care in sub-Saharan Africa. The intention of this recommendation is to introduce this concept as a feasible rescue method for clinicians in the region. The potential use of ECMO/ECLS will be discussed with focus on infrastructure for the retrieval services from the referring hospitals to designated ECMO centres.Conclusion: ECLS resources and time that should be committed to training of staff and on-going education should not be underestimated. ECLS should only be commenced, maintained and weaned in the hands of trained, experienced and knowledgeable medical personnel cognisant that the results will be benchmarked by ELSO (Extracorporeal Life Support Organization) and available for consumption in the public domain. Partnership models are key to the ECLS success with well-defined roles and responsibilities for each party. The possible way for ECMO/ECLS in Africa should be combining with a two-pronged education programme: Improving critical care services in themselves, and once they get to an acceptable level in this department then is to manage ECLS patients for a few hours. To upgrade critical care services, this is vital for Africa, and only then to introduce ECMO/ECLS

Early short course of neuromuscular blocking agents in patients with COVID-19 ARDS: a propensity score analysis

Background: The role of neuromuscular blocking agents (NMBAs) in coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS) is not fully elucidated. Therefore, we aimed to investigate in COVID-19 patients with moderate-to-severe ARDS the impact of early use of NMBAs on 90-day mortality, through propensity score (PS) matching analysis. Methods: We analyzed a convenience sample of patients with COVID-19 and moderate-to-severe ARDS, admitted to 244 intensive care units within the COVID-19 Critical Care Consortium, from February 1, 2020, through October 31, 2021. Patients undergoing at least 2 days and up to 3 consecutive days of NMBAs (NMBA treatment), within 48 h from commencement of IMV were compared with subjects who did not receive NMBAs or only upon commencement of IMV (control). The primary objective in the PS-matched cohort was comparison between groups in 90-day in-hospital mortality, assessed through Cox proportional hazard modeling. Secondary objectives were comparisons in the numbers of ventilator-free days (VFD) between day 1 and day 28 and between day 1 and 90 through competing risk regression. Results: Data from 1953 patients were included. After propensity score matching, 210 cases from each group were well matched. In the PS-matched cohort, mean (± SD) age was 60.3 ± 13.2 years and 296 (70.5%) were male and the most common comorbidities were hypertension (56.9%), obesity (41.1%), and diabetes (30.0%). The unadjusted hazard ratio (HR) for death at 90 days in the NMBA treatment vs control group was 1.12 (95% CI 0.79, 1.59, p = 0.534). After adjustment for smoking habit and critical therapeutic covariates, the HR was 1.07 (95% CI 0.72, 1.61, p = 0.729). At 28 days, VFD were 16 (IQR 0–25) and 25 (IQR 7–26) in the NMBA treatment and control groups, respectively (sub-hazard ratio 0.82, 95% CI 0.67, 1.00, p = 0.055). At 90 days, VFD were 77 (IQR 0–87) and 87 (IQR 0–88) (sub-hazard ratio 0.86 (95% CI 0.69, 1.07; p = 0.177). Conclusions: In patients with COVID-19 and moderate-to-severe ARDS, short course of NMBA treatment, applied early, did not significantly improve 90-day mortality and VFD. In the absence of definitive data from clinical trials, NMBAs should be indicated cautiously in this setting
