BackgroundProstaglandins are often administered after liver transplantation (LT) to diminish ischemia-reperfusion injury (IRI), to favor liver recovery and to prevent vascular thrombosis. Possible beneficial effects in adult liver recipients are controversial, but the single existing pediatric small case series shows no significant impact of prostaglandin administration after LT. The purpose of this study was to analyze the effect of the prostaglandin dinoprostone in pediatric liver recipients.MethodsA retrospective analysis of 41 children (<16 years) who underwent LT between March 2008 and December 2013 was performed. Dinoprostone was administered at a rate from 0.1 to a maximum of 0.6 μg/kg per hour immediately after LT and for a maximum of 5 days. Effect of dinoprostone on post-LT IRI and hepatic function up to 60 postoperative days and number of hypotensive episodes were analyzed.ResultsThe median cumulative dose of dinoprostone was 28 μg/kg (interquartile range, 23.2). Dinoprostone had no significant effect on post-LT liver function tests and factor V levels at any of the administered dosages. There was no significant association between the total quantity of vasopressor given and the number of hypotensive episodes observed in 8 patients. One patient showed a short-lasting hypotension, possibly related to the administration of dinoprostone.ConclusionsThis study did not show, at any dosage between 0.1 and 0.6 μg/kg per hour, any differences in beneficial or harmful effects of high- or low-dose dinoprostone administered immediately after pediatric LT on markers of IRI, hepatic function, or hypotension.
