【摘要】 连续硬膜外麻醉下行腹部手术后20例病人硬膜外腔注射高渗冷氯化钠溶液镇痛前、后及术后1.5～2年测定检查了疼痛阈值、感觉及运动功能,结果硬膜外注液后刀口疼痛缓解;疼痛阈值显著增高(P<0.01,P<0.05),36h后疼痛阈值降低并逐渐接近基值水平(P>0.05);7例病人出现短时间痛觉减退,感觉运动功能均存在;远期随访神经功能正常。结果表明硬膜外腔注射10％氯化钠溶液术后镇痛安全有效。更多还原

【Abstract】 We measured the pain threshold and the functions of sense and motor at the times of before and after epidural injection with hypertonic saline in 20 patients. The results as following:after epidural hypertonic saline the pain was relieved;the pain threshold increased in 24 hours(P<0. 01,P<0. 05). after 36 hours of injection it decreased from higher level to control level(P>0. 05) ; the functions of sense and motor were normal at 1.5—2 years after epidural injection. The results indicate that epidural injection with hypertonic saline is an effective and safe method for postoperative analgesia.更多还原
