Background: Timing of tracheostomy in COVID-19 patients supported with extracorporeal oxygenation membrane (ECMO) remains unclear. This study aims to compare the short-term outcomes in early (≤7 days from ECMO insertion) (ET) versus late (LT) tracheostomy. Methods: Charts of COVID-19 patients with tracheostomy from 2020 to 2021 were reviewed, retrospectively. Primary endpoint was in-hospital mortality. Secondary endpoints were analgesics/sedatives doses, length of treatment (LOT), and initiation of physiotherapy (PT). Results: Eight patients with ET were compared to six patients with LT. Mean age was 41.4±12.5 (ET) and 49.5±6.9 (LT) years. In both groups, 50% were male with comparable BMI. Twelve patients received venovenous (VV) and two received veno-arterial (VA) ECMO. Tracheostomy post ECMO cannulation was performed in 12 [ET:6(75%);LT:6(100%)] patients, whereas in the remaining two patients, it was performed immediately after initiation of ECMO support. Average duration of ECMO support was 48.0±21.3 (ET) than 42.2±27.0 (LT) days, P=0.34. Requirement of sedatives before [ET:6.4±4.6;LT:9.3±5.3;P=0.15] and after [ET:21.6±11.9;LT:12.2±14.0;P=0.11] along with analgesics before [ET:6.3±4.9;LT:7.0±6.5;P=0.41] and after [ET:19.0±6.9;LT:14.8±15.5;P=0.28] tracheostomy was comparable. No difference was observed in the LOT during sedatives/ analgesics dosing after tracheostomy. However, the LOT before tracheostomy was significantly longer in sedatives [ET:2.9±3.1;LT:11.8±6.2, P<0.01] and analgesics [ET:2.9±2.8;LT:9.8±3.5, P<0.01], explained by the longer interval between ECMO insertion and tracheostomy in LT group. Compared to LT, number of days from ECMO insertion to first PT session was significantly shorter in ET patients [ET:13.6±5.6;LT:26.5±4.5, P<0.01]. In-hospital mortality rate was 21.4% [ET:1(13%);LT:2(33%), P=0.33] patients with comparable ICU stay [ET:56.9±18.6;LT:50.2±26.4, P=0.30] between groups. Conclusion: Although the advantages of ET to reduce the requirement of analgesics and sedatives amongst COVID19 patients supported with ECMO were like LT group, ET was associated with early initiation of PT and improved survival.
