What researchers measure

Primary outcomes

  1. change of the hemodynamic profiles including cardiac index on NICOM during the TURP in elderly patients

    (Cardiac output, stroke volume, Stroke volume index, Total peripheral resistance, heart rate, blood pressure)

    Time frame: change from baseline 1 min before the anesthesia, 10 min after anesthesia, 10 min after surgery, 20 min after surgery, 30 min after surgery, at the end of the surgery

Secondary outcomes

  1. change of the electrolyte

    Time frame: from expected up to 3 months before surgery for preoperative evaluation to expected up to 3 hours after the end of surgery

  2. change of the hemoglobin

    Time frame: from expected up to 3 months before surgery for preoperative evaluation to expected up to 3 hours after the end of surgery

  3. estimated absorbed irrigation fluid during the surgery

    Fluid absorbed = % decrease in sodium x ECF (0.2 x body weight)

    Time frame: during the surgery

  4. incidence of TURP syndrome

    Time frame: followed for the duration of hospital stay, an expected average of 7 days.
