Abstract

BACKGROUND: Etomidate may be given in continuous infusion for maintenance of general anesthesia, although that practice is rarely seen due to beliefs that it has possibility of interfering with cortisol synthesis. However, etomidate is sometimes preferable choice as it has least influence on hemodynamics and rarely causes allergic reactions. ----- CASE DESCRIPTION: We describe a case of 13-year-old boy with aneurysm of left middle cerebral artery, planned for aneurysmal clipping, and previously treated for ruptured aneurysm of right middle cerebral artery. As he was tested and proved allergic to most of the anesthetic drugs, and stable hemodynamic conditions were of most importance during planned neurosurgery, general anesthesia was maintained with etomidate infusion. He was prepared with metilprednisolon, antihistaminic, and ranitidine before the surgery. Cortisol and adrenocorticotropic hormone levels were measured on three consecutive postoperative days. Only cortisol value, in the morning the day after the surgery, was below reference range, with the values back to normal until that evening. He was dismissed from the intensive care unit with Glasgow Coma Score 15. ----- CONCLUSION: Etomidate may be a choice for neuroanesthesia in specific group of people. We have good experience with our algorithm for continuous infusion of etomidate, with serum cortisol values in the reference range, if corticosteroids were not given before the surgery. Administration of metilprednisolon may diminish influence of perioperative stress on cortisol synthesis inhibition.
