Hemodynamic profile during laparoscopic cholecystectomy versus laparoscopic bariatric surgery--the impact of morbid obesity.

Abstract

Cardiac index showed significant decreasing trend in morbid obese patients compared to nonobese, which may reflect the effect of body weight on hemodynamics. On the other hand, other hemodynamic parameters was not altered by body weight. We believe that hemodynamics should be closely monitored during laparoscopic surgery with pneumoperitoneum.
