Clevidipine as an antihypertensive drug in three pheochromocytoma surgeries: Case series.

Introduction Laparoscopic adrenalectomy is the treatment of choice of pheochromocytoma. During the first surgical phase (pneumoperitoneum insufflation, tumor and veins handling), there is a risk of hypertensive crisis due to catecholamine release. After tumor excision, patients can suffer relative vasodilation and the residual effect of antihypertensive drugs, which results in arterial hypotension. For that reason, antihypertensive drugs used in the first phase should have a rapid onset of action, short half-life and no residual effect. Methods We report a series of three cases of patients with pheochromocytoma who were treated with laparoscopic adrenalectomy. They all received clevidipine infusion from the beginning of the surgery, before they had presented hypertension, to treat and try to minimize hypertensive peaks. Results In all patients, hypertensive peaks were controlled in a few minutes. After tumor resection, clevidipine infusion was stopped in all cases, and any patient required infusion of vasopressors. Discussion Clevidipine could be a first choice antihypertensive drug in pheochromocytoma surgery. Starting the infusion of clevidipine before the hypertensive peaks could help to make them less pronounced. [ABSTRACT FROM AUTHOR]
