ANESTHESIA FOR RESECTION OF RENIN PRODUCING ADRENAL TUMORA CASE REPORT

Background: Renin producing adrenal tumor is extremely rare. We experienced general anesthesia for resection of renin producing adrenal tumor. Case Report: A 67 years old female with hypertension had high plasma renin activity and serum aldosterone level with right adrenal tumor. She was scheduled for right adrenalectomy. After insertion of an epidural catheter, an arterial catheter, and a Swan-Ganz catheter, anesthesia was induced with diazepam, fentanyl and vecuronium, and maintained with isoflurane, nitrous oxide, and fentanyl. Diltiazem was infused to control blood pressure. Surgery was done under left lateral position without any complications. She was extubated in the operating room and discharged from high care unit to the ward 2 days later. Serum aldosterone levels decreased to the normal range before tumor removal and plasma renin activity decreased gradually to the normal range in 10 days. Blood pressure had been slightly high after surgery during her stay in the hospital. Conclusions: Resection of renin producing adrenal tumor was performed without any complications under general anesthesia with isoflurane, nitrous oxide, and fentanyl plus epidural block using diltiazem for control of blood pressure.
