Zhang et al reported the Peking criteria for the diagnosis of post-reperfusion syndrome (PRS) in a pediatric patient undergoing liver transplantation surgery. The authors are from the Capital Medical University and National Clinical Research Center for Digestive Diseases in Beijing.
Patient selection: pediatric patient undergoing liver transplantation
Timing: soon after reperfusion of the transplanted liver begins
Parameters:
(1) bradyarrhythmia (heart rate <= 85% of pre-reperfusion rate)
(2) new-onset, hemodynamically significant arrhythmia
(3) cardiac arrest
(4) severe hypotension (drop in systolic blood pressure unresponsive to 1 µg/kg epinephrine bolus)
(5) persistent hypotension (systolic blood pressure <= 70% of pre-reperfusion rate that lasts >= 5 minutes)
(6) new-onset vasoplegia (severe hypotension, high cardiac output, low systemic vascular resistance)
(7) prolonged vasopressor treatment
If one or more of these parameters is present, then the patient has the post-reperfusion syndrome.
