title: [Comparison of hemodynamic and ventilatory effects of pneumoperitoneum using carbon dioxide or abdominal suspension during laparoscopic cholecystectomy].
abstract: This study compares the cardio-respiratory effects of CO2 pneumoperitoneum to those of abdominal suspension (or laparolift) in laparoscopic cholecystectomy. Between september 1993 et may 1995, 31 patients participated in this non-randomized prospective trial. They consisted of 9 males et 22 females, with a mean age of 47.0 +/- 14 years. Sixteen patients were included in the CO2 group and 15 in the laparolift group. Both groups were comparable for age and gender. All patients were submitted to the same anaesthetic protocol. Repeated measurements of the respiratory 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 parameters, only the mean arterial pressure and cardiac frequency differed between the two groups, other hemodynamic parameters including left ventricular ejection fraction were comparable. Also, postoperatory hospital stay, OR time, per and postoperatory complications were comparable. With its stable hemodynamic and ventilatory pattern, abdominal suspension can constitute a safe and secure alternative to CO2 pneumoperitoneum in patients with respiratory dysfunction.
