Effect of racemic epinephrine on ventilatory function in the neonate postextubation.
The use of nebulized racemic epinephrine to improve ventilatory function in the newborn postextubation was studied. Forty-five infants intubated for more than 3 days were randomized to receive racemic epinephrine by nebulization immediately postextubation or to receive only warmed, humidified gas. Measurements of air flow, esophageal pressure, tidal volume, respiratory rate, and heart rate were made before treatment and every 10 min for 1 h after treatment. Resistance was calculated from recorded data. Changes from baseline values were calculated for each time period. Analysis of variance of these variables for treatment, sex, and time main effects and their interactions, with appropriate adjustments for covariables, was performed. Although some sex interactions were seen, there were no significant time effects or interactions. This study provides no evidence that using nebulized racemic epinephrine in infants postextubation improves ventilatory function.
