In this study, we evaluated the efficacy and safety of acetazolamide in the management of chronic metabolic alkalosis in neonates and infants with chronic respiratory insufficiency. A retrospective chart review of 90 patients treated with acetazolamide between 2006 and 2007 admitted to the neonatal intensive care unit was performed. Blood gases and electrolytes obtained at baseline and by 24 hours after acetazolamide administration were compared. Compared with baseline and after 24 hours of acetazolamide, mean measured serum bicarbonate (29.5+/-3.7 vs. 26.9+/-3.8 mEq/L, P<0.001) and base excess (10.0+/-3.4 vs. 4.8+/-4.0 mEq/L, P<0.001) were significantly lower. No significant differences in other electrolytes, blood urea nitrogen, and urine output were noted, except for an increased serum chloride and creatinine. Uncompensated respiratory acidosis developed in 4 (3.1%) treatment courses. Acetazolamide may be effective in decreasing serum bicarbonate in carefully selected patients. Its use and safety as an adjunctive therapy for chronic metabolic alkalosis in neonates and infants with chronic respiratory insufficiency needs further study.
