Brief Summary
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.

Outcome Measures
Primary Outcomes (3)
Cardiac cycle efficiency (CCE) was measured for evaluating cardiac performance
CCE(unit) indicates the ability of the cardiovascular system to maintain homeostasis at different energy levels. CCE was monitored using the uncalibrated pulse contour device MostCare (Vytech, Vygon, Padova, Italy)
The duration of the measurement was defined from one minute before induction to the end of the surgery
Longitudinal strain (LS) was measured for evaluating cardiac performance
LS (%) is a parameter that shows the percentage of dimensional change that occurs in the heart muscle. It is an indicator of the systolic functions of the left ventricle. LS was calculated by intraoperative transesophageal echocardiography.
LS was measured at supine position and 10 minute after trendelenburg position
Longitudinal strain rate (LSR) was measured for evaluating cardiac performance
LSR (%) is a parameter that shows the rate of dimensional change that occurs in the heart muscle. It is an indicator of the systolic functions of the left ventricle. LSR was calculated by intraoperative transesophageal echocardiography.
LSR was measured at supine position and 10 minute after trendelenburg position
Secondary Outcomes (10)
Stroke volume variation (SVV) was measured for evaluation of volume status
The duration of the measurement was defined from one minute before induction to the end of the surgery
Pulse pressure variation (PPV) was measured for evaluation of volume status
The duration of the measurement was defined from one minute before induction to the end of the surgery
Cardiac power output (CPO) was measured for evaluation of cardiac power reserve
The duration of the measurement was defined from one minute before induction to the end of the surgery
Cardiac index (CI) was measured for evaluating cardiac flow
The duration of the measurement was defined from one minute before induction to the end of the surgery
Dp/Dt was measured to assess cardiac systolic function
The duration of the measurement was defined from one minute before induction to the end of the surgery
- +5 more secondary outcomes
