Abstract: 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 (1 3.7±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° can shorten wake-up time and improve the quality of wake-up test during the procedure of PSO for AS patients with thoracolumbar kyphosis.
