Reperfusión rápida y homogénea como factor de riesgo del síndrome postreperfusión hepática durante transplante ortotópico de hígado

BACKGROUND AND OBJECTIVES: The revascularization of the graft remains as a crucial instant of the orthotopic liver transplantation (OLT) surgical procedure. About a third of the recipients suffer the postreperfusion syndrome (PRS), a combination of hypothermia, metabolic disorders and cardiovascular instability potentially leading to cardiac arrest. The objective of this study was to evaluate the speed-quality (SQR) of the graft's reperfusion as an independent predictor of PRS. METHODS: All eligible patients receiving an OLT in our institution from 1987 to march 2009 were included. The adjusted OR for SQRPRS association was obtained by means of logistic regression modeling including eight potential confounders. RESULTS: The proportion of recipients suffering PRS was highest when the SQR was identified as good (75.8%) compared to those with middle or poor SQR; the relative risk comparing good SQR with poor SQR was 12.9 (CI 95%: 2.1-528.8). The adjusted OR was 132.9 (95% CI: 10.5-1688.6) when comparing good with bad SQR and 90.9 (95% CI: 13.8-645.2) when comparing good with intermediate SQR. CONCLUSIONS: According to our results, SQR can be considered an unambiguous predictor of PRS.
