The study was based on a registry of cardiac arrest cases from 2009 to 2012 at a tertiary university hospital. We assessed patients' serum aminotransferase levels on return of spontaneous circulation (ROSC) and at 6, 12, 24, 48, and 72 hours postarrest. Hypoxic hepatitis was defined as a rapid increase in serum aminotransferase that reached at least 20 times the upper limit of normal. The patients were classified into 2 groups: the HH group and the non-HH group; we then analyzed the outcomes of the HH group. Independent predisposing factors to HH in this cohort were identified.
Of a total of 535 OHCA cases, 148 patients were enrolled in this study. Hypoxic hepatitis was identified in 13.5% (n = 20) of them. Serum aminotransferase rapidly increased in the first day after return of spontaneous circulation. Of the patients who developed HH, 5 (25%) survived to hospital discharge, and none of these individuals had good neurologic outcomes (Glasgow-Pittsburgh cerebral performance categories 1 and 2). Using multivariate logistic regression, we found that the no flow time was independent predictors of HH (odds ratio, 1.085 [95% confidence interval, 1.027-1.146]; P = .003).
Hypoxic hepatitis occurred frequently in survivors of OHCA. The no flow time was an independent risk factor for HH, which was significantly related to death and poor neurologic outcomes.
