ABSTRACT
<p><b>OBJECTIVE</b>To discuss the standards for clinical functional gradation and preoperative preparation of pheochromocytoma.</p><p><b>METHODS</b>According to the preoperative clinical manifestations and 24 hr urine catecholamine, 172 cases of pheochromocytomas were divided into 4 grades. Functionary grade 0 including 22 patients was given no volume expansion. Functionary Grade 1 consisted of 17 cases, 10 of which were given phenoxybenzamine orally 5 - 10 mg/d for 1 week (therapeutic group), the rest were control group; the results were analyzed by the chi(2) test. Functionary Grade 2 including 120 patients had phenoxybenzamine orally 30 - 240 mg/d for 4 weeks, hemodynamics and microcirculation image were standards for evaluating volume expansion. Functionary Grade 3 consisted of 13 patients including 1 with acute heart failure, 2 and 10 patients with past history of cerebral hemorrhage and hypertensive crisis respectively, they were treated with enough phenoxybenzamine and other emergent measures.</p><p><b>RESULTS</b>The perioperative blood pressure of Functionary Grade 0 had no fluctuation. The blood pressure of therapeutic group of Functionary Grade 1 had small range fluctuation (< 20 mm Hg), that of the control group was large (> 40 mm Hg). Chi(2) = 13.12, P < 0.01. The hemodynamics of Functionary Grade 2 and Grade 3 recovered within 24 hours postoperatively and no complications occurred.</p><p><b>CONCLUSION</b>According to the function of pheochromocytoma, it is safe and efficient to use different preoperative preparations. Hemodynamics and microcirculation image are golden standards for evaluating preoperative preparations.</p>
