Abstract

We assessed the incidence and predictors of intracranial hemorrhage (ICH) occurring during extracorporeal membrane oxygenation (ECMO) support. Of 154 patients who received ECMO, 12 (7.8%) developed ICH. Patients with ICH had a longer ECMO duration (9.41 vs. 5.37 days, p = 0.007), and higher activated clotting time (activated clotting time, p= 0.016). They also experienced higher frequency of bleeding at other sites (p = 0.017) and required more platelet transfusion (p = 0.016). Multivariate analysis showed that a longer ECMO duration (odds ratio [OR] = 1.074, 95% confidence interval [CI] = 1.005–1.148, p = 0.035) is independently associated with the risk of ICH. We recommend routine neurological checks, monitoring of coagulation parameters, and attempt earlier rather than late weaning from ECMO whenever feasible.
