[摘要] 目的 探讨预先给予去甲肾上腺素对高龄患者腰硬联合麻醉髋关节置换术后认知功能的影响。 方法 方便选择该院2015年6月—2016年6月择期行髋关节手术的高龄患者60例,按随机数字表法将患者分为两组对照组(n=30)和去甲肾上腺素组(n=30)。用MMSE量表进行认知功能评分,用ELISA法测定血浆S100-β蛋白浓度。结果 去甲肾上腺素组术后1 d MMSE评分和血浆S100-β浓度分别为(25.4±1.70)分和(1.26±0.85)μg/L;对照组术后1 d MMSE评分和血浆S100-β浓度分别为(23.2±2.40)分和(4.08±1.05)μg/L,比较差异有统计学意义(P<0.05);去甲肾上腺素组术后1 d POCD发生率明显低于对照组,比较差异有统计学意义(P<0.05)。 结论 预先给予去甲肾上腺素能明显改善腰硬联合麻醉髋关节置换术患者术后认知功能障碍。

[Abstract] Objective To discuss the effect of noradrenaline pre-treatment on the cognitive function of senile patients with combined spinal and epidural anesthesia after hip replacement. Methods 60 cases of senile patients with selective hip joint operation from June 2015 to June 2016 were randomly divided into two groups with 30 cases in each, and the cognitive function was scored by the MMSE scale and the plasma S100-β protein concentration was measured by the ELISA. Results The differences in the postoperative 1 d MMSE score and plasma S100-β concentration between the noradrenaline group and the control group had statistical significance[(25.4±1.70)scores,(1.26±0.85)μg/L vs (23.2±2.40)scores,(4.08±1.05)μg/L](P<0.05), and the incidence rate of 1 d POCD after operation in the noradrenaline group was obviously lower than that in the control group, and the difference had statistical significance(P<0.05). Conclusion The noradrenaline pre-treatment can obviously improve the cognitive function of senile patients with combined spinal and epidural anesthesia after hip replacement

术后认知功能障碍(Postoperative Cognitive Disfunction, POCD)是老年患者麻醉手术后常见的中枢神经系统并发症[1]。表现为认知功能异常、记忆缺损、人格改变和记忆力减退,髋关节置换术后患者认知功能减退的发生率达15%~60%。POCD是多种因素共同作用的结果,尤其低血压是造成老年人脑血流量降低及脑缺氧的重要因素[2]。该课题方便选取该院自2015年6月—2016年6月择期行髋关节手术的高龄患者60例,探讨预先给予升压药对高龄患者术后认知功能的影响,为降低高龄患者POCD的发生提供新思路和新方法,现报道如下。

1 资料与方法

1.1 一般资料

该研究已获该院伦理委员会批准,方便选取该院择期行髋关节手术的高龄患者60例,体重45~90 kg,性别不限,ASAⅡ级或Ⅲ级,排除标准:患者不能配合,术前MMSE基础值低于23分,患有神经系统或精神疾病,精神类药物服用史等。……
