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 |
