不同麻醉下胆囊切除术后早期的胃肠动力变化

为探讨不同麻醉下胆囊切除术对术后胃肠动力的影响，采用胃肠测压法记录胃肠移行性动力复合波（ＭＭＣ），对２０例单纯胆囊切除术患者（全麻和硬膜外麻醉各１０例）术后早期的胃肠动力变化进行了观察。结果：两组病例术后早期ＭＭＣ活动均消失，术后胃肠动力的恢复远较传统认为的快。术后０．５～２小时小肠ＭＭＣ重新出现，胃ＭＭＣ在术后５．５～１４小时恢复，术后２２～４３小时ＭＭＣ完全恢复正常。进食能使术后早期ＭＭＣ转变为消化期活动形式。比较两组患者术后胃肠动力恢复的各项指标发现，在全麻或硬膜外麻醉下进行手术，其术后胃肠动力的恢复过程无明显差异。

EFFECTS OF DIFFERENT ANAESTHESIA FOR CHOLECYSTECTOMY ON GASTROINTESTINAL MOTILITY

This study was designed to determine the effects of different anaesthesia on the postoperative gastrointestinal motility after cholecystectomy. Postoperative gastrointestinal motility were recorded continuously by means of gastrointestinal manometry in 20 patients subject to cholecystectomy (general anaesthesia 10, epidural anaesthesia 10). Normal migrating motor complex (MMC) was abolished during the early postoperative period in all patients. The time of reappearance of intestinal MMC varied from 0.5 to 2 hours . Gastric MMC recurred 5.5 to 14 hours postoperatively and the normal MMC completely recovered 22 to 43 hours after the operations. Ingestion of food changed the MMC into a fed pattern during the early postoperative period. There was no difference between the general anaesthesia group and epidural anaesthesia group in terms of gastrointestinal motility. The results indicate that postoperative gastrointestinal motility recovers faster than that was thought conventionally. Cholecystectomy under general anaesthesia or under epidural anaesthesia makes no difference in postoperative gastrointestinal motility.
