罗哌卡因复合液对术后膀胱痉挛镇痛的研究

目的探讨硬膜外持续榆注0．2％罗哌卡因、吗啡复合液对前列腺摘除术后膀胱痉挛镇痛的效果及其副作用。方法对40例AsAI～Ⅲ级，前列腺摘除术的患者随机分成A、B2组，A组患者术毕经硬外管注入0．2％罗哌卡因5ml，内含吗啡1．5-2mg作为负荷量，然后硬外管接美国Baxter镇痛泵，榆注0．2％罗哌卡因48ml，内含吗啡4mg、胃复安20mg，以1ml／h速度持续榆注；B组患者术毕经硬外管注入吗啡1．5-2mg作为负荷量，然后硬外管接美国Baxter镇痛泵，榆注0．9％N．S 48ml内含吗啡4mg、胃复安20mg，1ml／h速度持续输注。分别观察各组伤口疼痛VAS评分，膀胱痉挛性疼痛VAS评分，双下肢运动阻滞评分，同时观察恶心呕吐、皮肤瘙痒和呼吸抑制等发生率。结果2组对患者伤口镇痛效果好，VAS评分无差异，2组双下肢运动阻滞程度无明显差异，恶心、皮肤瘙痒每组各1例，2组均未出现呼吸抑制及呕吐。对膀胱痉挛性疼痛的抑制A组优于B组，2组有非常显著性差异（P〈0．01）。结论0．2％罗哌卡因、吗啡复合液用于前列腺摘除术后镇痛效果好，能明显抑制术后膀胱痉挛性疼痛，且副作用少。

Resection of vocal cord polyp through Micro-Stryker Instruments combined with cystoscope and selfretaining laryngoscope

Objective To evaluate the application of Micro-Stryker Instruments combined with cystoscope and self-retaining laryngoscope for the resection of vocal cord polyp.Methods Vocal cord polypectomy through Micro-Stryker Instruments combined with cystoscope and self-retaining laryngoscope were performed on 96 patients. Results All patients were followed up for three months. Of them, 87.5% were complete cured , 11.46% partial improved, and only 1.04% showed no effect. Conclusions Micro-Stryker Instruments combined with cystoscope and self-retaining laryngoscope was a valuable approach for the resection of vocal cord polyp,which was easy to operation, simple, safe, highly effective, and therefore it was suitable for broadly clinical application.
