Özet
Objective: This study aimed to compare intraoperative mechanical power (MP) between patients with obesity and patients without obesity undergoing robot-assisted laparoscopic radical prostatectomy (RALRP). Mechanical power reflects the ventilatory energy load and may influence postoperative pulmonary complications (PPCs). In the current study, we hypothesise that patients with obesity would be associated with significantly higher MP values. Method: This retrospective study included male patients who underwent elective RALRP between January 2023 and June 2023. Obesity was classified according to World Health Organization criteria. The intraoperative data included measurements taken at three specific time points: 10 minutes after inducing anesthesia (T1), 10 minutes after establishing pneumoperitoneum (T2), and 10 minutes after placing the patient in the Trendelenburg position (T3). The primary outcome of this study is the measurement of intraoperative MP at T3. Results: A total of 56 patients’ data were included in the analysis. The primary outcome, MP at T3, was 13.7 J min-1 in the group with obesity and 12 J min-1 in the group without obesity (p = 0.001). At the other time points, MP, peak inspiratory pressure, and driving pressures were also significantly higher in the group with obesity. Overall PPC incidence was 19.5%, with 38.1% in the group with obesity and 8.6% in the group without obesity. Conclusion: During RALRP, MP and airway pressures were significantly higher in patients with obesity. Although complications were more frequent in this group, the majority were mild, and there were no significant differences in intensive care unit or overall hospital stay between the groups.
