摘要:
目的 观察超声引导下腰骶丛神经阻滞联合全麻应用于高龄患者髋关节置换术对患者术后临床疗效的影响。 方法 选择2018年1月—2020年1月中国人民解放军陆军第七十二集团军医院骨科收治的80例择期行全髋关节置换术的老年高龄患者纳入研究,随机数字表法分为观察组和对照组,每组40例,2组患者术式一致,观察组麻醉方式采用超声引导下腰骶丛神经阻滞联合全麻,对照组麻醉方式为全麻,麻醉过程中均采用喉罩通气,脑电图双频指数(BIS)保持在45~55,记录2组患者入室前(T0)、麻醉10 min(T1)、手术开始30 min(T2)、术后2 h(T3)的心率(HR)、平均动脉压(MAP),记录术后6、12、24、36、48、72 h的VAS评分,记录患者术中输液量、舒芬太尼用量、手术时间、术中出血量、术后拔管时间及排气时间,并进行对比分析。 结果 观察组患者术中输液量、舒芬太尼用量、手术时间、术中出血量、术后拔管时间及排气时间显著低于对照组(均P<0.05);观察组T1、T2时刻的HR、MAP均低于对照组(均P<0.05);观察组患者术后6、12、24、36 h VAS评分低于对照组(均P<0.05)。 结论 超声引导下腰骶丛神经阻滞联合全麻应用于高龄患者髋关节置换术时,与全麻相比,减少了术中阿片类镇痛药的用量,同时镇痛效果更佳,降低术中输液量和出血量,缩短手术时间、术后拔管时间及排气时间,患者麻醉满意度高。 Abstract:Objective To observe the effect of ultrasound-guided sacral plexus block combined with general anesthesia on the postoperative clinical effect of hip replacement in elderly patients. Methods Total 80 elderly patients undergoing elective total hip replacement from January 2018 to January 2020 in our department were selected. They were randomly divided into experimental and control groups with 40 cases per group. The operation methods of the two groups were the same. The observation group was anesthetized by ultrasound-guided lumbosacral plexus block combined with general anesthesia, while the control group was anesthetized by general anesthesia. Laryngeal mask ventilation was used during anesthesia, and the bispectral index (BIS) of EEG was maintained at 45-55. The heart rate (HR) and mean arterial pressure (map) were recorded before entering the room (T0), 10 min after anesthesia (T1), 30 min after operation (T2) and 2 h after operation (T3), and 6, 12, 24, 36, 48 and 72 h after operation VAS scores were recorded, including intraoperative infusion volume, sufentanil dosage, operation time, intraoperative blood loss, postoperative extubation time and exhaust time. The data of two groups were compared and analysed. Results The intraoperative infusion volume, sufentanil dosage, operation time, intraoperative blood loss, postoperative extubation time, and exhaust time in the observation group were significantly lower than those in the control group (all P < 0.05). The HR and MAP of the observation group at T1 and T2 were lower than those of the control group (all P < 0.05). Vas scores at 6, 12, 24, and 36 h in the observation group were lower than those in the control group (all P < 0.05). Conclusion Compared with general anesthesia, ultrasound-guided lumbosacral plexus block combined with general anesthesia can reduce the dosage of opioid analgesics during the operation, and has better analgesic effect. It can reduce the amount of intraoperative infusion and blood loss, shorten the operation time, postoperative extubation time and exhaust time, and has high anesthesia satisfaction. -
