What are the special postoperative problems associated with resection of a pheochromocytoma?
The most common problem seen in the postoperative period is mild hypotension. Significant hypotension usually does not last beyond emergence from anesthesia. As discussed previously, hypotension is treated initially with fluid therapy and only occasionally requires an inotrope or vasopressor infusion. Hypertension in the post-tumor resection period suggests the presence of residual or addi-tional tumor. In this case, α- and β-adrenergic blockade are continued. Sodium nitroprusside is added as required. Hypoglycemia may occur in the postoperative period and may be due to sudden withdrawal of catecholamines and possibly to the metabolic effects of β-blockers.
