Effect Of Trendelenburg Position And Pneumoperitoneum On Optic Nerve Sheath Diameter In Robot-Assisted Prostatectomy

NCT07491198 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 50

No results posted yet for this study

Summary

This prospective study aims to evaluate the effect of steep Trendelenburg position and pneumoperitoneum on optic nerve sheath diameter in patients undergoing robot-assisted laparoscopic radical prostatectomy and open radical prostatectomy under general anesthesia. Increased intracranial pressure may occur during robotic surgery due to pneumoperitoneum and head-down positioning. Optic nerve sheath diameter measured by ocular ultrasonography is a non-invasive method used to assess intracranial pressure changes. Hemodynamic and respiratory parameters will also be recorded during surgery. The results of this study may help to better understand the physiological effects of surgical position and pneumoperitoneum during prostatectomy procedures.
