Circulatory Function in Laparoscopic Radical Cystectomy for Bladder Cancer

February 16, 2022 updated by: DAN HUANG, RenJi Hospital

Preliminary Study on the Changes of Perioperative Circulatory Function in Patients Undergoing Laparoscopic Radical Cystectomy for Bladder Cancer

To optimize the perioperative management of patients undergoing laparoscopic radical cystectomy(LPC) for bladder cancer through observation of perioperative changes of Brain Natriuretic Peptide(BNP), stroke volume variation(SVV), central venous pressure(CVP) and the use of transthoracic echocardiography(TTE).

Study Overview

Detailed Description

Long term pneumoperitoneum and steep trendelenburg in LPC for bladder cancer influence perioperative circulatory function, resulting in a series of pathophysiological changes. BNP is of high sensitivity and specificity in the evaluation of cardiac function. SVV and CVP are dynamic and static indices to predict fluid responsiveness. TTE is a good indicator of volume and cardiac function.Thus, we conducted the trial to assess the perioperative circulatory function in patients undergoing LPC. We hypothesized that long term pneumoperitoneum and steep trendelenburg in LPC for bladder cancer would increase perioperative blood volume and influence cardiac function.
