Twenty-seven patients who were moderately hypotensive during uncemented total hip replacement were compared with a group of normotensive patients. There was no statistical difference (P less than 0.05) in blood loss measured at time of operation, following operation or in the calculated loss. Hypotension, which is known to be dangerous in the elderly, conferred no benefit and should be avoided.
27例在非骨水泥型全髋关节置换术中出现中度低血压的患者与一组血压正常的患者进行了比较。在手术时、术后测量的失血量或计算出的失血量方面,两组之间无统计学差异(P<0.05)。低血压在老年人中已知是危险的,并无益处,应予以避免。
