Evaluation of Cardiac Functions in Deep Trendelenburg Position

Robotic-assisted laparoscopic prostatectomy (RALP) is a surgical method with good short-term results and accepted as the gold standard because of its minimal invasiveness. The pneumoperitoneum and deep Trendelenburg position (at least 25°-45° upside down) required for RALP surgeries can cause significant pathophysiological changes in both the pulmonary and cardiac systems, as well as complicate hemodynamic management.In this study, investigators aimed to determine the changes in the cardiovascular system during deep Trendelenburg position with the hemodynamic parameters monitored by the pressure record analytical method (PRAM) and the Longitudinal Strain measured with simultaneous transesophageal echocardiography.
