Abstract

A 66 year old male with a suprarenal pheochromocytoma on the left side was treated preoperatively with oral phenoxybenzamine 20 mg, b. i. d. for 2 weeks. The night before surgery, phenobarbital 100 mg & diazepam 5 mg were given orally. One hour before induction, diazepam 10 mg i. m. was given. Preinduction BP was 210/140 and HR was 130/min. After diazepam 20 mg i. v, BP lowered to 200/130 and HR lowered to 126/min. With commencement of sodium nitroprusside i. v. dripping, a BP of 160/100 and HR of 118 were maintained. Following Thiopental sodium 250 mg i. v., mask induction was started with N2O-O2-Enflurane and pancuronium 4 mg i. v., after 5 minutes, a #8.5 tube was intubated and pindolol 0.16 mg was injected to prevent tachycardia. We maintained a tolerable BP and pulse by repeatedly adding a bolus i. v. injection of phenoxybenzamine 1 to 2 mg during tumor manipulation and removal. No arrhythmia was noted throughout the procedure, except tachycardia. After removal of the tumor, with rapid blood transfusion and fluid infusion plus dopamine i. v. dripping, a tolerable BP and pulse was maintained.
