直肠癌经腹会阴联合根治术,是直肠癌根治术最常见的一种手术方式。此种手术创伤大,手术时间长,直肠深藏在小骨盆内,要求麻醉肌肉松弛,需要硬膜外阻滞范围广。此类病人常伴贫血、低蛋白血症,术中低血压发生率高,麻醉处理有一定的特殊性。本文对89例直肠癌经腹会阴联合根治术围术期低血压的原因进行分析。 1 临床资料 1.1 一般资料:本组89例,男51例,女38例,年龄17～78岁,≥65岁24例,平均年龄58.4岁。术前病人多消瘦、贫血、低蛋白血症。 1.2 麻醉方法:本组麻醉均采用硬膜外阻滞,采用两个穿刺点,选T_12～L_1(或其上下一个间隙)
Rectal cancer through the abdomen perineum combined with radical mastectomy, is the most common type of rectal cancer surgery. Such surgical trauma, surgery for a long time, rectum deep in the small pelvis, requiring anesthesia muscle relaxation, the need for a wide range of epidural block. Such patients often with anemia, hypoproteinemia, high incidence of intraoperative hypotension, anesthesia treatment has a certain specificity. In this paper, 89 cases of rectal cancer transabdominal perineal radical resection of the causes of perioperative hypotension were analyzed. 1 Clinical data 1.1 General Information: The group of 89 patients, 51 males and 38 females, aged 17 to 78 years, ≥ 65 years old in 24 cases, mean age 58.4 years. Preoperative patients more weight loss, anemia, hypoproteinemia. 1.2 anesthesia methods: epidural anesthesia were used in this group, using two puncture points, select T_12 ~ L_1 (or a gap between the upper and lower)
