Cardiopulmonary function and laparoscopic cholecystectomy

Hemodynamic and pulmonary changes during and after laparoscopic cholecystectomy A comparison with traditional surgery

“…The main advantages of LC over OC were found in the postoperative course. As has already been observed by many authors [9,13,15,17,18,21,23], LC patients were characterized by a lesser reduction in overall lung function, lower morbidity, a faster recovery, and earlier discharge from hospital. In particular, our LC series experienced (a) a lower reduction of oxygenation and ventilation-perfusion mismatching, as demonstrated by the lower increase in (Aa)PO 2 ; (b) a higher and faster restoration of ventilatory parameters, in particular for FVC and FEF 75-85% values; (c) no change in inspiratory and expiratory muscle strength (versus a severe decrease of the latter parameter for the overall OC postoperative course); (d) no significant abnormalities in cardiovascular function (versus 8.3% after OC); and (e) no major pulmonary complications and a lesser incidence of subclinical atelectasis (versus 8% after OC).…”

“…There is a great deal of disagreement among the authors of the most recent publications on the hemodynamic and ventilatory effects of laparoscopic surgery [2,6,23]. Conflicting data has been reported on the incidence of cardiorespiratory complications in patients undergoing cholecystectomy (LC), even though LC is the most common as well as the safest of all laparoscopic procedures [15,17,18].…”

Effects of pneumoperitoneum on intraoperative pulmonary mechanics and gas exchange during laparoscopic gastric bypass

“…Without ventilatory changes, PIP can increase by 17% to 109% during pneumoperitoneum [3,7,18,20]. In our study, ventilatory adjustments were performed during laparoscopic GBP to limit the rise in PIP, ETCO 2 , and PaCO 2 .…”

Randomized trial of different intraabdominal pressures and acid-base balance alterations during laparoscopic cholecystectomy

“…Laparoscopy with carbon dioxide (CO 2 ) pneumoperitoneum (capnoperitoneum) significantly influences both cardiovascular and respiratory functions [6,25].…”
