Randomized Controlled Trial Clinical Trial
Randomized clinical trial of the effect of pneumoperitoneum on cardiac function and haemodynamics during laparoscopic cholecystectomy.
Conventional laparoscopic cholecystectomy (CLC) with carbon dioxide pneumoperitoneum may cause major cardiovascular changes. The aim of this study was to evaluate the effect of carbon dioxide pneumoperitoneum and positional changes on haemodynamics and cardiac function in patients assigned randomly to CLC or gasless laparoscopic cholecystectomy (GLC). ⋯ Carbon dioxide pneumoperitoneum was associated with increased preload and afterload in patients undergoing laparoscopic cholecystecomy. It also decreased heart performance (fractional shortening), but did not affect cardiac output.
