目的:研究不同麻醉方法对高龄甲状腺瘤患者早期术后认知功能的影响。方法:随机选择60例年龄≥65岁的甲状腺瘤手术老年患者,其中男38例,女22例,分为全身麻醉组(A组,30例)和颈丛阻滞组(B组,30例),由同一试验者采用神经心理学测试技术简易...目的:研究不同麻醉方法对高龄甲状腺瘤患者早期术后认知功能的影响。方法:随机选择60例年龄≥65岁的甲状腺瘤手术老年患者,其中男38例,女22例,分为全身麻醉组(A组,30例)和颈丛阻滞组(B组,30例),由同一试验者采用神经心理学测试技术简易智力状态检查(MMSE)两组患者术前1d、术后12h和术后24 h的认知功能。排除有精神病史或长期服用影响神经系统功能药物的患者。结果:二组术后12h的MMSE值低于术前(P<0.05),组间比较差异无统计学意义(P>0.05);A组术后12 h和24 h POCD的发生率为分别16.7%和3.3%,B组的术后12 h和24 h POCD的发生率为分别10.0%和3.3%(P>0.05)。结论:与颈丛阻滞相比,全身麻醉不会增加高龄甲状腺瘤患者早期术后认知功能障碍的发生率。展开更多
