Résumé

Background A strategy that limits tidal volumes and inspiratory pressures, improves outcomes in patients with the acute respiratory distress syndrome (ARDS). Extracorporeal carbon dioxide removal (ECCO 2 R) may facilitate ultra-protective ventilation. We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of venovenous ECCO 2 R in supporting ultra-protective ventilation in moderate-to-severe ARDS. Methods MEDLINE and EMBASE were interrogated for studies (2000–2021) reporting venovenous ECCO 2 R use in patients with moderate-to-severe ARDS. Studies reporting ≥10 adult patients in English language journals were included. Ventilatory parameters after 24 h of initiating ECCO 2 R, device characteristics, and safety outcomes were collected. The primary outcome measure was the change in driving pressure at 24 h of ECCO 2 R therapy in relation to baseline. Secondary outcomes included change in tidal volume, gas exchange, and safety data. Results Ten studies reporting 421 patients (PaO 2 :FiO 2 141.03 mmHg) were included. Extracorporeal blood flow rates ranged from 0.35-1.5 L/min. Random effects modelling indicated a 3.56 cmH 2 O reduction (95%-CI: 3.22–3.91) in driving pressure from baseline ( p < .001) and a 1.89 mL/kg (95%-CI: 1.75–2.02, p < .001) reduction in tidal volume. Oxygenation, respiratory rate and PEEP remained unchanged. No significant interactions between driving pressure reduction and baseline driving pressure, partial pressure of arterial carbon dioxide or PaO 2 :FiO 2 ratio were identified in metaregression analysis. Bleeding and haemolysis were the commonest complications of therapy. Conclusions Venovenous ECCO 2 R permitted significant reductions in ∆P in patients with moderate-to-severe ARDS. Heterogeneity amongst studies and devices, a paucity of randomised controlled trials, and variable safety reporting calls for standardisation of outcome reporting. Prospective evaluation of optimal device operation and anticoagulation in high quality studies is required before further recommendations can be made.
