Abstract:

Objective To systematically evaluate the incidence of thrombotic complications in patients treated with extracorporeal membrane oxygenation technology (ECMO). Methods Articles reporting ECMO and incident thrombosis published before December 2022 were systematically searched in the PubMed, EMBASE, Wanfang and CNKI database using the following keywords: “Extracorporeal Membrane Oxygenation or ECMO”, “thrombus or complication”. Two investigators were responsible for screening eligible articles based on the inclusion and exclusion criteria. Meta-analysis and subgroup analysis were performed using Review Manager 5.4 software. The quality of the included articles was evaluated according to the Newcastle-Ottawa Scale (NOS) scoring system. Results A total of 16 literatures involving 1136 patients were selected. Meta-analysis showed that the incidence of thrombosis in ECMO patients was 52.0%(95% C I: 0.30-0.88) and I 2 was 91% ( P<0.01). Subgroup analysis showed that the incidence of ECMO concurrent thrombosis in patients <45 years old and 45-59 years old was 27.0%(95% C I: 0.14-0.50) and 53.0%(95% C I: 0.29-0.97), respectively. The incidence of patients with a mean duration of ECMO ≤10 days and >10 days was 50.0%(95% C I: 0.34-0.74) and 39.0%(95% C I: 0.11-1.38), respectively. The incidence of thrombosis with a body mass index(BMI) of 24-27.9 kg/m2 and ≥28 kg/m2 was 27.0%(95% C I: 0.07-1.07) and 66.0% (95% C I: 0.36-1.23), respectively. The incidence of thrombosis detected by the anticoagulation monitoring methods of partial thromboplastin time (APTT), activated clotting time (ACT) and anti-factor-Xa (anti-Xa) was 57.0%(95% C I: 0.47-0.69), 13.0%(95% C I: 0.08-0.20) and 45.0% (95% C I: 0.36-0.57), respectively. Conclusion The incidence of thrombotic complications in patients treated with ECMO is 52.0%. Patients with an older age, shorter duration of ECMO, greater BMI and monitored for APTT have a higher incidence of thrombotic complications.
