Hemodynamic profile during laparoscopic cholecystectomy versus laparoscopic bariatric surgery: the impact of morbid obesity.
The present study investigated the hemodynamic profile using impedance cardiography (ICG) monitor during pneumoperitoneum for laparoscopic cholecystectomy versus bariatric surgery in order to determine the impact of body weight on hemodynamics. METHODS. 32 adult patients (two groups, each 16 patients) were studied. Group 1 (16 patients) scheduled to undergo laparoscopic cholecystectomy (lapchole) with body mass index (BMI) 28 +/- 5 kg/m2. ⋯ 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.
