Hemodynami~; during laparoscopic cholecystectomy under general anesthesia [ Desflurane in NeO/Oa (50%) 1 were investigated in 29 patients with ASA I, 11, During the surgery, intraabdominal pressure was maintained automatically at 12 to 14 mmHg by a COe insufflator and minute ventilation was controlled and adjusted to avoid hypercapnia. Hemodynamics were measured before anesthesia, after the induction of anesthesia, after tilting into 10" head-up position, 5 min, 30 min after peritoneal insufflation, after deflation and at the end of operation, Induction of anesthesia decreased blood pressure (BP) significantly and increased heart rate (HR) significantly. Tilting the patient to the head-up position decreased BP more. Peritoneal insufflation resulted in a significant increase (12%) of mean arterial pressure, a significant increase (18%) of heart rate, Administration of increasing concentration of desflurane, via its vasodilatory activity, may have partially blunted these hernodynamic changes. These results demonstrate that laparoscopy for cholecystectorny in head-up position results in significant hemodynarnic changes in healthy patients, particularly during pneumoperitoneum.
