术中不同头部体位对行脊柱后路截骨矫形术患者唤醒时间和苏醒质量的影响

Effects of different head positions during operation on wake-up time and quality among ankylosing spondylitis patients with thoracolumbar kyphosis following pedicle subtraction osteotomy

目的探讨两种不同术中头部体位对强直性脊柱炎胸椎腰后凸畸形患者行脊柱后路截骨矫形术中唤醒时间和苏醒质量的影响。方法将60例强直性脊柱炎胸腰椎后凸畸形行后路截骨矫形术的患者,按手术先后次序编号,采用随机数字表法随机分为实验组和对照组,每组各30例。两组患者静脉全麻后,取头低脚低呈弓形俯卧体位,实验组将手术床床头抬高10°;对照组手术床床头未抬高,观察两组患者术中唤醒时间及苏醒质量。结果实验组患者唤醒时间为(13.7±2.0)min,对照组为(24.2±2.7)min;实验组患者苏醒质量优于对照组,两组比较,差异均有统计学意义(P<0.01或P<0.05)。结论行脊柱后路截骨矫形术中将患者头部抬高10°可缩短患者术中唤醒时间,提高苏醒质量。

Objective To investigate the effects of different head positions during operation on wake-up time and quality among ankylosing spondylitis（AS） patients with thoracolumbar kyphosis following pedicle subtraction osteotomy（PSO）. Methods Sixty patients were included in this study. All of them, treated with intravenous anesthesia, took the bow-prone position. The patients were randomly divided into two groups： the experiment group where the head was elevated by 10° and the control group where the head was not elevated. The two groups were compared in respect of wake-up time and quality of wake-up test. Results The wake-up time in the experiment group was significantly shorter as compared to that of the control group（13.7 ±2.0 min vs. 24.2±2.7min, P〈0.05）. The wake-up quality was better as well. Conclusion Elevation of the head by 10 ocan shorten wake-up time and improve the quality of wake-up test during the procedure of PSO for AS patients with thoracolumbar kyphosis.
