Operative Treatment Of Pheochromocytoma Report Of 13 Cases

Objective:To investigate the preoperative preparation for pheochromocytoma.Methods:The data of 13 cases of pheochromocytoma,who were treated in our hospital from 2000to 2006,were collected and reviewed on the preoperative preparation.Phenoxybenzamine was given to 13cases and during preoperative period,lasting for 2 weeks.In 28%of the casesβadrenergic blocker was given for control of heart rate.Results:In 13 cases,blood pressure remained stable at the level of 120/80 mm Hg(1 mm Hg=0.133 kPa) or so.No paroxysmal hypertension,palpitation and sweating occurred after use ofα-blockade.The heart rate re-mained 80～85 times/ min.No arrhythmia occurred.Peri-microcirculation was obviously improved.The tumor size(range,3～12 cm in diameter;mean,5.2 cm) was not related to the function and length of preoperative use of the medications.In most cases,blood pressure fluctuated(reaching up to 200/180 mm Hg) when they experienced anesthesia induction and tumor crush during operation.However,it was easy to control.Postoperative blood pressure remained stable.Conclusions:The full preoperative preparation for patients with pheochromocytoma is essential for the safety and success of anesthesia and operation.
