Sodium nitroprusside and propranolol therapy for management of postcoarctectomy hypertension.

Previously the combination of trimethaphan and reserpine was utilized, but the incidence of adverse reactions was high. We recently have used the regimen of sodium nitroprusside and propranolol in six patients with gratifying results. This report reviews the problem as well as our use of nitroprusside and propranolol in managing hypertension following coarctation repair.
