Abstract

People addicted to opium rarely develop intra-abdominal adhesions after abdominal surgery. We aimed to evaluate the effect of opium or morphine on preventing postoperative adhesions in rats. Sixty-three rats were randomly divided into a control group, opium-addicted group, and morphine-addicted group in a double-blind study. Drug dependency was checked by using naloxone. Animals were then operated on and the cecum was abraded. At reoperation 3 weeks later the magnitude of adhesions was evaluated by a scoring system. There was a significant difference between the control, opium-addicted, and morphine-addicted groups with regard to the length (P < .001), thickness (P < .05), and severity of adhesions (P < .05). Opium or morphine reduces the severity of postoperative adhesions. Elucidation of the opioid receptor(s) involved in this process would enable the use of selective ligands and offer a pharmacologic strategy in preventing adhesion formation.

摘要

吸食鸦片成瘾的人腹部手术后很少发生腹腔粘连。我们旨在评估鸦片或吗啡对预防大鼠术后粘连的作用。在一项双盲研究中,63只大鼠被随机分为对照组、鸦片成瘾组和吗啡成瘾组。使用纳洛酮检查药物依赖性。然后对动物进行手术并擦伤盲肠。3周后再次手术时,通过评分系统评估粘连程度。对照组、鸦片成瘾组和吗啡成瘾组在粘连长度(P <.001)、厚度(P <.05)和粘连严重程度(P <.05)方面存在显著差异。鸦片或吗啡可降低术后粘连的严重程度。阐明参与此过程的阿片受体将有助于使用选择性配体,并为预防粘连形成提供一种药理学策略。
