چکیده

Rapid cyclic fluctuations of blood pressure in patients with a pheochromocytoma have rarely been reported. The suitable conditions to induce this phenomenon are not adequately known. We report here a patient with an adrenal pheochromocytoma who showed this phenomenon after oral administration of labetalol.

Rapid cyclic fluctuations of blood pressure associated with an adrenal pheochromocytoma.

We present a patient with an adrenal pheochromocytoma with an unusual pattern of periodic alternating hypertension and hypotension. Alpha-adrenergic blockade alone failed to affect this pattern, which was abolished only after fluid repletion. The efficacy of volume expansion in ultimately correcting the wide fluctuations of blood pressure implicates a possible reflex neurogenic mechanism for th...

Labetalol pretreatment reduces blood pressure instability during surgical resection of pheochromocytoma.

BACKGROUND To evaluate the effect of pretreatment with the mixed alpha- and beta-adrenergic blocker, labetalol, on blood pressure instability during surgical resection of pheochromocytoma. METHODS Blood pressure stability and surgical results were compared between patients in the saline (n = 11) and labetalol (n = 15) groups. Anesthesia was induced with fentanyl, sodium thiopental and atracur...

Hyperadrenergic syndrome in severe tetanus: extreme rise in catecholamines responsive to labetalol.

The hyperadrenergic syndrome that occurs in tetanus is characterised by hypertension, tachycardia, and increased systemic arteriolar resistance. A 74 year old man with tetanus was found to have very high catecholamine concentrations--as high as those in phaeochromocytoma--and the fluctuations in blood pressure and heart rate were measured to see whether they paralleled changes in the catecholam...
