Minimal access surgery (MAS) can be a lengthy procedure when compared to open surgery and therefore surgeon fatigue becomes an important issue and surgeons may expose themselves to chronic injuries and making errors. There have been few studies on this topic and they have used only questionnaires and electromyography rather than direct measurement of energy expenditure (EE). The aim of this study was to investigate whether the use of an armrest could reduce the EE of surgeons during MAS.
Sixteen surgeons performed simulated MAS with and without using an armrest. They were required to perform the time-consuming task of using scissors to cut a rubber glove through its top layer in a triangular fashion with the help of a laparoscopic camera. Energy consumptions were measured using the Oxycon Mobile system during all the procedures. Error rate and duration time for simulated surgery were recorded. After performing the simulated surgery, subjects scored how comfortable they felt using the armrest.
It was found that O(2) uptake (VO(2)) was 5 % less when surgeons used the armrest. The error rate when performing the procedure with the armrest was 35 % compared with 42.29 % without the armrest. Additionally, comfort levels with the armrest were higher than without the armrest. 75 % of surgeons indicated a preference for using the armrest during the simulated surgery.
The armrest provides support for surgeons and cuts energy consumption during simulated MAS.
与开放手术相比，微创手术（MAS）可能需要更长的时间，因此外科医生疲劳成为一个重要问题，外科医生可能会暴露于慢性损伤和错误之中。关于这个主题的研究很少，而且它们只使用了问卷和肌电图，而不是直接测量能量消耗（EE）。本研究旨在探讨使用扶手是否可以减少 MAS 期间外科医生的 EE。
16 名外科医生在使用和不使用扶手的情况下进行了模拟 MAS。他们需要使用腹腔镜相机以三角形的方式用剪刀切开橡胶手套的顶层，以完成耗时的任务。在所有手术过程中，使用 Oxycon Mobile 系统测量能量消耗。记录模拟手术的错误率和持续时间。完成模拟手术后，受试者对使用扶手的舒适度进行评分。
发现使用扶手时 O（2）摄取（VO（2））减少了 5%。使用扶手进行手术的错误率为 35%，而不使用扶手时为 42.29%。此外，使用扶手时的舒适度高于不使用扶手时。75%的外科医生表示在模拟手术中更喜欢使用扶手。
扶手为外科医生提供了支撑，并减少了模拟 MAS 期间的能量消耗。
