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 2～6μg/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.
