[Changes in hemodynamics at different stages of laparoscopic cholecystectomy]

Central hemodynamic parameters were studied by tetrapolar rheography in 147 patients aged 53-87 years during laparoscopic cholecystectomies. The operations were performed under endotracheal N2O+O2 narcosis and midazolam, phentanyl, droperidol, and listenon. The greatest changes of hemodynamics were observed during CO2 insufflation in the abdominal cavity, particularly in the patients with decreased cardiovascular reserve potential. Cardiovascular disease is not a contraindication for laparoscopic intervention under conditions of hemodynamic monitoring.
