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
