PURPOSE: Whether therapeutic hypothermia (TH) adds to the risk of bleeding in patients on extracorporeal life support (ECLS) peri-cardiac arrest remains unknown.
MATERIAL AND METHODS: Single center retrospective study on patients receiving veno-arterial ECLS peri-cardiac arrest ± TH at 32-34 °C (January 2009-December 2015).
PRIMARY OUTCOME: major bleeding (including intracerebral hemorrhage, ICH) < 72 h of cardiac arrest. Logistic regression and marginal structural models were used to analyze associations with major bleeding.
RESULTS: Of 66 patients receiving ECLS, 36 were treated with TH. Major bleeding occurred in 14 patients (39%) treated with ECLS+TH and in 17 patients (57%) with ECLS alone. ICH was reported in 3 (8%) and one patient (3%), respectively. There was no difference in mortality, but lung injury occurred more often in ECLS+TH. A platelet count <60 × 109/L but not TH was associated with major bleeding (including ICH). The estimated causal risk ratio of TH on the occurrence of major bleeding (including ICH) at 72 h post cardiac arrest was 0.95 (95%CI 0.62-1.45).
CONCLUSIONS: Bleeding complications were common in our study. However, TH (32-34 °C) was not associated with an increased risk of major bleeding in patients on ECLS peri-cardiac arrest.
