Table 1 Peking criteria for the definition of severe postreperfusion syndrome in liver transplantation

From: Elevated effluent potassium concentrations predict the development of postreperfusion hyperkalemia in deceased liver transplantation: a retrospective cohort study

Criteria

Definition

Time of diagnosis

Significant arrhythmias

Bradyarrhythmia

Decrease of HR ≥ 15%

Early reperfusion period

New-onset arrhythmias

Hemodynamically significant arrhythmias (hyperkalemia-related or others)

Early reperfusion period

Cardiac arrest

Loss of spontaneous heartbeat and requires cardiac massage

Early reperfusion period

Refractory hypotension

Severe hypotension

Decreased MAP unresponsive to an accumulated bolus of 1 µg/kg EP

Early reperfusion period

Persistent hypotension

Decrease of MAP ≥ 30% for ≥ 5 min regardless of the dosage of EP

Early reperfusion period

New-onset vasoplegia

NE ≥ 0.5 µg/kg/min, MAP < 50 mmHg, normal or elevated CO, and low SVR

Late reperfusion period

Prolonged vasopressor treatment

Postreperfusion hypotension requiring prolonged NE infusion to ICU

At the end of the surgery

  1. The presence of one or more of the seven criteria indicates severe postreperfusion syndrome. CO: cardiac output, EP: epinephrine, HR: heart rate, NE: norepinephrine, ICU: intensive care unit, MAP: mean arterial pressure, SVR: systemic vascular resistance
