Abstract
Experimental studies demonstrated a severe cardiac load of the CO2 pneumoperitoneum caused by an accelerated after and a decreased preload Patients displaying cardiovascular risks are therefore often rejected from laparoscopic surgery Hence the pathophysiological changes and the intraoperative risk of the CO2 pneumoperitoneum in highrisk cardiopulmonary patients NYHA II–III n= 15 undergoing laparoscopic cholecystectomy are described The changes in cardiac after and preload seem to be due to the elevated intraabdominal pressure rather than transperitoneally resorbed CO2 and are reversible by desufflation In one patient conversion to open operation had to be performed because of a severe drop in cardiac output and right ventricle ejection fraction Mixed oxygen saturation was predicting intraoperative worsening in this case The described pathophysiological changes may seem to be well tolerated even in highrisk cardiac patients Monitoring of hemodynamics should include an arterial catheter line and blood gas analyses Pharmacologic interventions or pressureless laparoscopic procedures might not be necessary as long as laparoscopic cholecystectomy is performed
