Plasma bromide concentrations of 25 patients were determined before and after halothane anesthesia. A high correlation (r > .70) between exposure to halothane in MAC hours and plasma bromide levels 24, 48 and 72 hours later was found. Peak bromide levels occurred 48-72 hours after anesthesia in 16 patients (64 per cent), and ranged from 52 μg/ml (0.65 mEq/l) to 180 μq/ml (2.25 mEq/l). Bromide levels remained elevated for prolonged periods (at least 22 days in some patients). Possible sedative or psychoactive effects of increased plasma bromide levels are discussed.
