Objective:To investigate the effects of reduced bleeding of combined using aprotinin,hemodilution and induced hypotension in patients undergoing neurosurgery and influence to Lac,NE,urine volume.

Aim:To observe the effects of sevoflurane combined with nitroglycerine induced hypotension on the balance of cerebral oxygen supply and consumption and renal function.

Object:To estimate the safe in the induced hypotension with nitroprusside by the change of regional cerebral oxygen saturation(rSO_2) in young and old age-group.

The Clinical Research of Deliberate Hypotension Induced by Sevoflurane-Remifentanil Compounded Anesthesia in the Clamp Operation of Intracranial Aneurysm;

Methods A series of rescue measures were carried out on 60 TBI patients:①shortened the waiting time before the operation; ②established multiple intravenous routes,including the deep vein intubations,used relief of the intracraninal pressure and the deliberated hypotension during the operations,to maintain the smooth circulation and breath, and ensure th.

Purpose To study the effects of deliberated hypotension combined with acute isovolemic hemodilution on blood volume, cardiac preload, extra vascular lung water and plasma oncotic pressure in patients undergoing total hip replacement (THR).

In group l(n=26) deliberated hypotension was induced by 0.
