Abstrakt: Objective: To evaluate the efficacy of inhaled albuterol for treatment of hyperkalemia in premature neonates by conducting a prospective, randomized placebo-controlled and double-blinded clinical trial.
Study Design: Neonates <2000 g receiving mechanical ventilation with central serum potassium > or =6.0 mmol/L (6.0 mEq/L), were randomly assigned to treatment or placebo groups. Albuterol (400 microg) or saline was given by nebulization. The dose was repeated every 2 hours until the potassium level fell below 5 mmol/L (maximum 12 doses) or there were signs of toxicity.
Results: Nineteen patients completed the study (8 in the albuterol and 11 in the saline group). Serum potassium levels declined rapidly in the first 4 hours in the albuterol group, from 7.06 +/- 0.23 mmol/L to 6.34 +/- 0.24 mmol/L (P =.003) versus no significant change in the saline group (6.88 +/- 0.18 mmol/L to 6.85 +/- 0.24 mmol/L; P =.87). At 8 hours, the fall continued to be greater in the albuterol group versus the saline group (5.93 +/- 0.3 mmol/L and 6.35 +/- 0.22 mmol/L, respectively; P =.04).
Conclusion: Albuterol inhalation may be useful in rapidly lowering serum potassium levels in premature neonates.
