5 Versus 10 mcg Norepinephrine Bolus in Treatment of Postinduction and Early Intraoperative Hypotension in Emergency Abdominal Surgery
Sponsor: Cairo University
Summary
Postinduction hypotension is a frequent intraoperative complication, particularly in emergency abdominal surgery due to factors such as sepsis, hypovolemia, and limited preoperative cardiac assessment. Because it can lead to serious organ injury, prompt prevention and management are essential. Vasopressors, including ephedrine, phenylephrine, and norepinephrine, are commonly used, with NE gaining interest as an intraoperative bolus despite uncertainty about the optimal dose in general surgery population The aim of this study is to compare 5 mcg to 10 mcg norepinephrine bolus for treatment of postinduction hypotension and early intraoperative in emergency abdominal surgery.

Interventions
Norepinephrine 10 mcg
Norepinephrine dose of 10 mcg will be given if patient developed hypotension (mean arterial pressure \<65 mmHg). The norepinephrine bolus (10 mcg) will be repeated if mean arterial pressure is not restored within 2 min. Norepinephrine infusion will be started if hypotension persisted after three boluses.
Norepinephrine 5 mcg
Norepinephrine dose of 5 mcg will be given if patient developed hypotension (mean arterial pressure \<65 mmHg). The norepinephrine bolus (5 mcg) will be repeated if mean arterial pressure is not restored within 2 min. Norepinephrine infusion will be started if hypotension persisted after three boluses.
