Enalaprilat controls postoperative hypertension while maintaining cardiac function and systemic oxygenation after...

Area of Science:

• Anesthesiology and Critical Care Medicine
• Cardiovascular Pharmacology
• Neurosurgery

Background:

• Postoperative hypertension is a common complication following neurosurgery.
• Effective management of blood pressure is crucial to prevent adverse neurological outcomes.

Purpose of the Study:

• To evaluate the efficacy and safety of intravenous enalaprilat in managing postoperative hypertension after supratentorial intracerebral tumor resection.

Main Methods:

• A prospective, randomized, single-blind, controlled trial involving 18 neurosurgical patients.
• Intravenous enalaprilat (0.015 mg/kg) administered to 9 patients with defined postoperative hypertension.
• Central hemodynamics and systemic oxygenation monitored for four hours post-injection.

Main Results:

• Enalaprilat significantly lowered blood pressure within 15 minutes, with effects lasting over four hours (p = 0.008).
• The primary mechanism was a reduction in systemic vascular resistance.
• No significant impact on cardiac performance, heart rate, or systemic oxygenation was observed.

Conclusions:

• Intravenous enalaprilat is an effective and safe option for treating postoperative hypertension in neurosurgical patients.
• The drug favorably influences central hemodynamics without compromising cardiac function or oxygen delivery.
