Evaluation of Periop Biochemical Stress Factors in Craniotomy Neurosurgical Procedure With Respect to Preop Hypertension

Summary

Perioperative hypertension is commonly associated with surgical craniotomy. As the sympathetic nervous system and the renin-angiotensin-aldosterone system play a key role in the development of this hypertension, preoperative single dose therapy with a -adrenergic receptor blocker or an angiotensin converting enzyme (ACE) inhibitor may be useful in preventing this. To assess this as well as to study potential markers of these two systems, the investigators will perform a randomized, double blind, placebo controlled study to compare the single dose effect of preoperative administration of a -receptor blocking drug (atenolol) and an ACE inhibitor (lisinopril) with a control group receiving a placebo tablet (glucose) on perioperative hypertension in craniotomy patients.
