Hypertension and tachycardia during adrenal manipulation.

The purpose of this report is to draw attention to haemodynamic changes during intraoperative adrenal gland manipulation. Severe hypertension, ventricular tachycardia and subendocardial ischaemia occurred during the manipulation of adrenal gland in a patient who underwent live related donor nephrectomy. The patient responded well to intravenous lidocaine. Plasma norepinephrine concentration was elevated at the time of event. Further investigations after surgery excluded the possibility of phaeochromocytoma. In two years follow-up patient remains well. Suspicion for the cause of the event remains the excessive release of catecholamines with manipulation of a normal adrenal gland. The presence of halothane might have contributed to the arrythmia.
