Surgery is accepted as one of the most demanding professions that create both physical and mental strain on the performers. Therefore, the authors aimed to elucidate the mental burden of surgeons, which is dedicated to operative stress. They also tested the hypotheses that participating in surgery creates mental stress on surgeons that leads to cardiovascular changes, and that this stress is more pronounced for actual operators than for first assistants. The method chosen for this purpose was an analysis of heart rate variability. Twelve surgeons (five plastic surgery staff and seven plastic surgery residents) were monitored by a digital ambulatory Holter recorder on at least two occasions. Half of the recordings were carried out on operating days and the other half on office days. Heart rate variability indices (low frequency, high frequency, high frequency/low frequency ratio, and heart rate) were analyzed from those recordings using computerized research tool software. The heart rate variability indices of the operators showed statistically significant differences between operating days and office hours in favor of an increased sympathetic and decreased parasympathetic activity for the former. For first assistants, three of the parameters, with the exception of heart rate, changed in favor of a sympathetic predominance over parasympathetic activity; these changes were also statistically significant. These results showed a sympathetic hyperactivity for both operators and first assistants during the operations. When the sympathovagal balance of the actual operators was compared with that of assistants, the former group showed a more pronounced sympathetic arousal. This difference is accepted as a proof for the mental stress of the surgery being the main factor responsible for the sympathetic hyperactivity that we detected during the operations. Surgeons continuously face a unique mental strain that other professions rarely bring forth, and these psychological stressors are associated with alterations in cardiac autonomic control that may contribute to the development of cardiac disease. Prolonged sympathetic hyperactivity could anticipate cardiac discomfort in more experienced surgeons with marginal cardiac reserve. Such cardiac diseases would be reconsidered as occupation-related illnesses, which might be reimbursed to the physician. In addition, the legal responsibility of surgeons concerning their unfavorable results might be assessed with more understanding with a realization of their undue working conditions.
手术被认为是要求最为严苛的职业之一,会给从业者带来身心双重压力。因此,作者旨在阐明外科医生的精神负担,这种负担与手术压力相关。他们还检验了以下假设:参与手术会给外科医生造成精神压力,进而导致心血管变化;并且这种压力对于实际操作的外科医生而言比第一助手更为明显。为此所选用的方法是分析心率变异性。12名外科医生(5名整形外科工作人员和7名整形外科住院医师)至少在两个不同时段接受了数字式动态心电图记录仪的监测。一半的记录是在手术日进行的,另一半是在办公日进行的。使用计算机研究工具软件从这些记录中分析心率变异性指标(低频、高频、高频/低频比值和心率)。实际操作的外科医生的心率变异性指标在手术日和办公时间之间显示出统计学上的显著差异,表明前者交感神经活动增强,副交感神经活动减弱。对于第一助手而言,除心率外,有三个参数的变化有利于交感神经占优势;这些变化在统计学上也具有显著性。这些结果表明,手术过程中实际操作的外科医生和第一助手均存在交感神经活动亢进。将实际操作的外科医生与助手的交感神经 - 迷走神经平衡进行比较时,前者表现出更明显的交感神经兴奋。这种差异被视为手术精神压力是导致我们在手术过程中检测到的交感神经活动亢进的主要因素的证据。外科医生持续面临着其他职业很少出现的独特精神压力,而这些心理应激源与心脏自主神经控制的改变有关,可能会导致心脏病的发生。长期的交感神经活动亢进可能会使心脏储备能力有限的经验更为丰富的外科医生出现心脏不适。这类心脏病可被重新认定为与职业相关的疾病,医生可能会得到相应补偿。此外,认识到外科医生不利的工作条件后,对于他们在手术结果不佳方面的法律责任或许会有更具理解性的评估。
