Abstract:
Objective To study the effects of deliberated hypotension combined with acute simple hemodilution on blood loss,postoperative hemoglubin of the patients undergoing spinal side(back) protrude correction(SSP).Methods Twenty four ASA grade Ⅰ to Ⅱ patients undergoing elective SSP were randomly divided into two groups:control group(n=12) and hypotensive group(n=12).The all patients received with general anesthesia.In the hypotensive group:acute simple hemodilution was accomplished with infusion of lactated Ringer's solution and Gelofusine of as three times as blood loss.Deliberated hypotensin was induced and maintained with 0 01% sodium nitroprusside 2～6?g/kg/min iv.Intraoperative blood loss,blood transfused volume during operation and postoperative hemoglobin were recorded and compared between both groups.Results Blood loss was about 51% lower in the deliberated hypotensive group than that in the control group at the end operation.The average volume of transfused blood during operation was(1200?140)ml in control group,blood transfusion was(400?128)ml in the hypotensive groups.Conclusion Deliberated hypotension combined with acute simple hemodilution can significantly decrease the intraoperative blood loss and the SSP operation can be better tolerated for the indicated patients.
