340例妇科术后患者硬膜外注入吗啡2mg(生理盐水稀释至10ml),100例注入生理盐水10ml为对照组。结果:吗啡组Ⅰ、Ⅱ级镇痛达98.8％,对照组为13.0％.两组恶心、呕吐及排气时间;呼吸、血压及脉搏;血气分析、K~+、No~+、Cl~-离子及AG等均无差异。但两组均为高AG型酸中毒,其原因为术前术后禁食所致,与应用吗啡无关。研究证明本法术后镇痛好、安全、适用,无呼吸抑制现象。
340 cases of postoperative gynecological patients were injected epidural morphine 2mg (saline diluted to 10ml), 100 cases injected saline 10ml for the control group. Results: The analgesia of group Ⅰ and Ⅱ of morphine group was 98.8%, and that of control group was 13.0% .Nausea, vomiting and excretion time, respiration, blood pressure and pulse rate, blood gas analysis, K ~ +, No ~ + and Cl ~ There was no difference between ion and AG. However, both groups were high AG acidosis, the reason for the preoperative and postoperative fasting, has nothing to do with the application of morphine. Research shows that postoperative analgesia good, safe, suitable, no respiratory depression.
