Remifentanil preventing hemodynamic changes during laparoscopic adrenalectomy for pheochromocytoma

In this prospective case-series study, a balanced anesthetic scheme of sevoflurane in nitrous oxide supplemented with remifentanil and sustained neuromuscular block was applied in nine patients scheduled for laparoscopic adrenalectomy for pheochromocytoma. Laparoscopic adrenalectomy to treat pheochromocytoma results in marked catecholamine release during pneumoperitoneum and tumor manipulation. Remifentanil infusion was adjusted to maintain systolic arterial pressure between 120-170 mmHg. Increased infusion rate of remifentanil was used [up to 3 ug/kg/min] to prevent and treat marked hemodynamic changes from catecholamine release during tumor manipulation. Hypotension after tumor removal was treated with additional colloids fluids and decreasing the remifentanil infusion rate by 25-50%
