Abstract:
Objective To evaluate the effects of deliberated hypotension combined with acute hypervolemic hemodilution (AHH) on safety,operation time, blood loss,postoperative hemoglobin (Hb) and hematocrit (Hct) of the patients undergoing endoscopic nose surgery.Methods Twenty ASA grade I to II patients undergoing selective endoscopic nose surgery were divided randomly into two groups: control group (n=10) and hypotensive group (n=10). All patients received general anesthesia. In the hypotensive group, AHH was accomplished with infusion of HAES and lactated Ringer's solution after endotracheal intubation and before operation. Deliberated hypotension was induced and maintained with nitroprusside 0 5～3 0?g?kg -1 ?min -1 iv. Operation time, intraoperative blood loss, postoperative hemoglobin (Hb) and hematocrit (Hct) and hemodynamics during operation were recorded and compared between the both groups.Results Operation time was about 44% shorter in the hypotensive group than that in the control group. Blood loss was significantly lower in the hypotensive group than that in the control group (P
