假设：在腹腔镜乙状结肠切除术和常规乙状结肠切除术中，心率变异性测量的精神紧张程度不同。设计：前瞻性随机研究。地点：大学医院。参与者：两名外科医生进行了10次常规乙状结肠切除术和10次腹腔镜乙状结肠切除术，交替担任主要外科医生和助手。干预：在手术过程中连续记录外科医生和助手的心电图，并离线分析心率变异性。主要观察指标：心率变异性由功率谱分析确定，以每分钟心率为单位，高频(HF)和低频(LF)成分以归一化单位为单位，以及低频/高频(LF/HF)比值。结果：得到了下列变量的心率、HF、LF和LF/HF比率：腹腔镜手术：87.9，14.7，90.1，7.5；传统手术：90.2，17.1，87.6，6.4；外科医生：94.0、13.5、91.4、8.4；第一助理：84.1、17.8、86.3、5.6；较有经验的外科医生：93.1、16.5、87.8、6.4；经验较少的外科医生：85.0、14.8、90.0、7.5。低频/高频比值显著升高(P<0.05)。
Hypothesis: Mental strain measured by heart rate variability differs during laparoscopic and conventional sigmoid resections.Design: Prospective randomized study.Setting: University hospital.Participants: Two surgeons performed 10 conventional and 10 laparoscopic sigmoid resections, alternating roles as primary surgeon and assistant. The kind of technique was randomly chosen each time.Intervention: Electrocardiograms of the surgeon and assistant were continuously recorded during the procedures and heart rate variability was analyzed off-line. The first 10 procedures (5 laparoscopic and 5 conventional) were performed by the more experienced and the next 10 by the less experienced surgeon.Main Outcome Measures: Heart rate variability was determined by power spectral analysis as heart rate in beats per minute, high frequency (HF) and low frequency (LF) components in normalized units, and LF/HF ratio.Results: Results are given for heart rate, HF, LF, and LF/HF ratio for the following variables: laparoscopic surgery: 87.9, 14.7, 90.1, 7.5; conventional surgery: 90.2, 17.1, 87.6, 6.4; surgeon: 94.0, 13.5, 91.4, 8.4; first assistant: 84.1, 17.8, 86.3, 5.6; more experienced surgeon: 93.1, 16.5, 87.8, 6.4; and less experienced surgeon: 85.0, 14.8, 90.0, 7.5. The LF/HF ratio was significantly higher (P
