|
Arterial pressure increased from normal to 80~90 mrn Hg, 90~100 mm Hg & 110 ~130 mmHg when the intracrania1 pressure was mechanically elevated to 20~40, mm Hg, 50~70 mm Hg & 90~l00mmHg respectively, while rabbits (average 3kg) were anesthetized with subcuttneous urethane, (1gm/kg), In these circumstances, there was no specific change in the intracranial pressure, or arterial pressure between two groups when one was given intravenous 5mg/kg of gallamine and the other 0. 5mg /kg of intravenous pancuronium. But in a group given 1mg/ kg of d-tubocurarine, arterial pressure decreased significantly, while intracranial pressure was not changed particularly arterial pressure decreased more significantly when the intracranial pressure was increased to 90~100 mm Hg, resulting in an initial arterial pressure of 110~130 mm Hg. Therefore the authors recommend.
d-tubocurarine as the agent of choice among these three non-depolarizing muscle relaxants for induction and maintpnance of anesthesia in patients with elevated intracranial pressure pre-operatively. |
