ABSTRACT
@#Objective To observe the effects of preoperative aprotinin infusion on blood loss and brain edema in patients undergoing meningioma resection.Methods 80 were randomized to receive intravenous normal saline(control group) or aprotinin 2.0×106 KIU(aprotinin group) before operation.The intraoperatively hemostatic appearance was assessed by the surgeon in the form of quantitative scoring.The postoperative degree of brain edema was assessed by radiologist according to the appearance of computer tomography.Results There were no statistic differences in general information,intraoperatively infused volume,urine volume,and the quantitative score of postoperatively brain edema(P>0.05).The operation duration was(209±63) min and(305±93) min,blood loss was 420(150～3270) ml and 610(110～2430) ml in the aprotinin group and the control group respectively(P<0.05).There was statistic difference in the score of intraoperatively hemostatic apperance(P<0.05).Conclusion In the resection of meningeoma,aprotinin was infused with a dose of 2.0×106 KIU preoperatively can shorten the duration of operation and reduce the intraoperative blood loss,but it cannot relieve the degree of postoperatively brain edema.
