The preoperative blood loss during resection of the colon, abdominal-perineal excision of the rectum and cystectomy, according to the method of Bricker, was studied from anaesthetic reports. The period under study was 18 months. A total of 97 patients were divied into two main groups according to the type of anaesthesia (general anaesthesia and general anaesthesia combined with epidural analgesia), as well as into sub-groups according to the type of operation. An evaluation was made of the blood loss, peroperative mean arterial blood pressure and the duration of the operation. In contrast to reports published earlier on other types of operation, we have been unable to demonstrate a significant reduction in the blood loss of patients given general anaesthesia plus epidural analgesia, despite a lower mean arterial blood pressure during the operation. We ignored any possible postoperative beneficial effect of epidural anaesthesia.
根据麻醉报告，对采用布里克氏法进行结肠切除、直肠腹会阴联合切除及膀胱切除术时的术前失血量进行了研究。研究时间为18个月。根据麻醉类型（全身麻醉和全身麻醉联合硬膜外镇痛），将97例患者分为两个主要组，并根据手术类型进一步分为亚组。对失血量、术中平均动脉血压和手术持续时间进行了评估。与先前发表的关于其他类型手术的报告不同，尽管术中平均动脉血压较低，但我们未能证明全身麻醉加硬膜外镇痛患者的失血量有显著减少。我们忽略了硬膜外麻醉术后可能存在的有益效果。
