摘要: 目的 观察0.5％轻比重罗哌卡因腰硬联合麻醉在老年患者人工股骨头置换术中的有效性及安全性.方法 选择40例ASAⅡ-Ⅲ级择期行人工股骨头置换术的老年患者,随机分为2组:罗哌卡因(R组)和丁哌卡因(B组),观察2组患者麻醉前和注药后5 min,10 min,20 min,30 min各时间点收缩压(SBP)、舒张压(DBP)、心率(HR).记录感觉阻滞起效时间、平面固定时间、感觉阻滞时间、运动阻滞起效时间、达最大运动阻滞时间、运动阻滞的持续时间.记录术中使用麻黄碱、阿托品以及发生不良反应的例数.结果 R组的SBP、DBP、HR在注药后观察的各时点较麻醉前无显著变化,而B组的SBP、DBP、HR在注药后10 min、20 min、30 min与麻醉前基础值和同时点R组的相比显著降低,R组的感觉阻滞时间和运动阻滞持续时间明显短于B组,R组中使用麻黄碱、阿托品的例数较B组少,寒战和恶心呕吐的例数也较B组少.结论 0.5％罗哌卡因腰硬联合麻醉用于老年患者人工股骨头置换术是安全有效的.
