The objective of this prospective study, performed at two tertiary referral centers in the West Midlands, was to determine if operating has an effect on a surgeon's baseline tremor. A total of 10 head and neck surgery consultants, 2 ENT registrars and 19 normal controls participated in the study. The interventions were preoperative and postoperative tremor measurements for surgeons and pre and post-days' desk work for controls, with the main outcomes measure being the percentage change in tremor. No difference in baseline tremor was determined between consultants and registrars. Operating led to an increase in hand tremor in all subjects. Tremor increases in all subjects were directly proportional to the length of the time spent in operating. Operating compared to a normal day's desk work increased tremor by a factor of 8.4. In conclusion, surgeons should be aware that their tremor will increase as an operation progresses. More complex parts should be performed as early in the day as possible, or, in the case of a very long operation, a change of surgeons may occasionally be necessary.
这项前瞻性研究在西米德兰兹郡的两个三级转诊中心开展，目的是确定手术是否会对外科医生的基线震颤产生影响。共有10名头颈外科顾问医生、2名耳鼻喉科住院医生和19名正常对照者参与了该研究。干预措施为对外科医生术前和术后的震颤进行测量，对对照者进行术前和术后数天的案头工作，主要结局指标为震颤的百分比变化。未发现顾问医生和住院医生之间的基线震颤存在差异。手术导致所有受试者手部震颤增加。所有受试者的震颤增加与手术时长成正比。与正常一天的案头工作相比，手术使震颤增加了8.4倍。总之，外科医生应意识到，随着手术的进行，他们的震颤会增加。更复杂的部分应尽早在当天完成，或者，在手术时间很长的情况下，偶尔可能需要更换外科医生。
