Abstract

Abstract: Aim: Hypoxic hepatitis (HH) may complicate the course of resuscitated out-of-hospital cardiac arrest (OHCA) patients admitted in intensive care unit (ICU). Aims of this study were to assess the prevalence of HH, and to describe the factors associated with HH occurrence and outcome. Methods: We conducted an observational study over a 6-year period (2009–2014) in a cardiac arrest center. All non-traumatic OHCA patients admitted in the ICU after return of spontaneous circulation (ROSC) and who survived more than 24 h were included. HH was defined as an elevation of alanine aminotransferase over 20 times the upper limit of normal during the first 72 h after OHCA. Factors associated with HH and ICU mortality were picked up by multivariate logistic regression. Results: Among the 632 OHCA patients included in the study, HH was observed in 72 patients (11.4% (95% CI: 9.0%, 14.1%)). In multivariate analysis, time from collapse to ROSC [OR 1.02 per additional minute; 95% CI (1.00, 1.04); p = 0.01], male gender [OR 0.53; 95% CI (0.29, 0.95); p = 0.03] and initial shockable rhythm [OR 0.35; 95% CI (0.19, 0.65); p < 0.01] were associated with HH occurrence. After adjustment for confounding factors, HH was associated with ICU mortality [OR 4.39; 95% CI (1.71, 11.26); p < 0.01] and this association persisted even if occurrence of a post-CA shock was considered in the statistical model [OR 3.63; 95% CI (1.39, 9.48); p = 0.01]. Conclusions: HH is not a rare complication after OHCA. This complication is mainly triggered by the duration of resuscitation and is associated with increased ICU mortality.
