OBJECTIVES
To evaluate how the prone position influences mechanical power (MP) during elective surgical procedures.
METHODS
In this prospective study carried out at Karadeniz Ereğli Government Hospital, Zonguldak, Turkey, from January 2024 to February 2024, 76 patients under general anesthesia were evaluated at different time points during the surgical procedure. Hemodynamic, laboratory, and mechanical ventilation data were also recorded.
RESULTS
The MP increased in the prone position at the beginning of surgery. Transitioning to the supine position at the end of surgery led to a decrease in MP. At the end of surgery, the mean MP in supine and prone positions was found to be higher compared to those measured in the first hour of surgery. Mechanical power and body mass index (BMI) exhibited a significant positive correlation.
CONCLUSION
Position changes influence MP. Returning to the prone position increases MP. An increase in BMI is associated with an increase in MP..
目的
评估手术过程中俯卧位如何影响机械功率（MP）。
方法
本研究为前瞻性研究，于 2024 年 1 月至 2 月在土耳其宗古尔达克市卡拉德尼兹埃雷利政府医院进行，共评估了 76 例全麻下的患者。在手术过程中的不同时间点记录血流动力学、实验室和机械通气数据。
结果
手术开始时，患者处于俯卧位时 MP 增加。手术结束时转换为仰卧位会导致 MP 降低。手术结束时，仰卧位和俯卧位的平均 MP 高于手术开始后第一个小时测量的值。机械功率和体重指数（BMI）呈显著正相关。
结论
体位变化会影响 MP。恢复俯卧位会增加 MP。BMI 增加与 MP 增加有关。
