Hemodynamic Effects of Pressure-regulated Volume Control Mode in Patients With Diastolic Dysfunction Undergoing Radical Cystectomy

"Cardiac output non-invasive monitor for measuring SV. Hemodynamic variables including heart rate (HR), mean arterial blood pressure (MAP), central venous pressure (CVP), stroke volume (SV), stroke volume index (SVI), cardiac output (COP), cardiac index (CI), systemic vascular resistance (SVR), systemic vascular resistance index (SVRI), thoracic fluid content (TFC), corrected flow time (FTC), index of contractility (ICON), and systolic time ratio (STR), Arterial oxygen saturation (Sao2), oxygen delivery (DO2) and oxygen delivery index (DO2I) will be recorded.~These variables will be obtained before induction of anaesthesia (T1) skin incision (T2), then every 30 min till the resection of the urinary bladder (T3a, T3b, T3c, …. etc). The mode of ventilation will swift to the other mode 5 minutes after cystectomy (T4), then every 30 min till end of the urinary diversion (T5a, T5b, T5c, …. etc), end of surgery (T6), and postoperative every 4h for 24 hours( P1-P6)."
