Heart rate variability (HRV) has recently been used to detect autonomic nerve tone, which is affected by various stresses. To test out hypothesis that HRV can determine surgical stress, we examined perioperative HRV in 30 patients with surgical treatment. Relations between HRV and factors of surgical stresses, such as duration of the operation, amount of blood loss at the operation, and developments of complications, were evaluated. Mean heart rate (HR) increased and other HRV indices decreased postoperatively. Most indices correlated significantly to the duration of the operation and amount of blood loss at the operation on postoperative day 1. Only the standard deviation of normal to normal RR intervals (SDNN) and HRV triangular index showed significantly low values in complicated patients. HRV measurement in the perioperative period showed a significant relation to surgical stress. The present results indicated that HRV may provide useful information with respect to surgical stress.
心率变异性（HRV）最近被用于检测受各种压力影响的自主神经张力。为了验证HRV能够确定手术应激的假设，我们对30例接受手术治疗的患者进行了围手术期HRV检查。评估了HRV与手术应激因素之间的关系，如手术持续时间、术中失血量和并发症的发生情况。术后平均心率（HR）升高，其他HRV指标降低。术后第1天，大多数指标与手术持续时间和术中失血量显著相关。只有正常到正常RR间期的标准差（SDNN）和HRV三角指数在发生并发症的患者中显示出显著较低的值。围手术期HRV测量显示与手术应激有显著关系。目前的结果表明，HRV可能提供有关手术应激的有用信息。
