COMPARISON OF HEMODYNAMIC AND RESPIRATORY EFFECT DURING LAPAROSCOPIC CHOLECYSTECTOMY USING CO2 OR LAPAROLIFT

This study compares the cardio-respiratory effects of CO2 pneumoperito neum to those of abdominal suspension (or laparolift) in laparoscopic cholecystectomy. Between september 1993 et may 1995, 31 patients parti cipated in this nonrandomized prospective trial. They consisted of 9 m ales et 22 females, with a mean age of 47,0 +/- 14 years. Sixteen pati ents were included in the CO2 group and 15 in the laparolift group. Bo th groups were comparable for age and gender. All patients were submit ted to the same anaesthetic protocol. Repeated measurements of the res piratory and cardiovascular function were made during the intervention . End tidal CO2, minute ventilation, peak inspiratory pressure showed superior elevations in the CO2 group. And for the hemodynamic paramete rs, only the mean arterial pressure and cardiac frequency differed bet ween the two groups, other hemodynamic parameters including left ventr icular ejection fraction were comparable. Also, postoperatory hospital stay, OR time, per and postoperatory complications were comparable. W ith its stable hemodynamic and ventilatory pattern, abdominal suspensi on can constitute a safe and secure alternative to CO2 pneumoperitoneu m in patients with respiratory dysfonction.
