An Evaluation of Twice-Daily Dosing of Caffeine for Apnea of Prematurity.

OBJECTIVE

Preterm infants often require caffeine for the treatment of apnea. While the maintenance dose of caffeine citrate is usually administered once daily per FDA labeling, many providers administer the maintenance dose in two divided doses. This study evaluated the effectiveness of a twice daily dosing regimen of caffeine for apnea of prematurity.

METHODS

This was a retrospective analysis conducted from 2013-2018 that included preterm infants who received caffeine that was dosed both once and twice daily respectively. The primary outcome of our study was a composite of the number of apneic and bradycardic events for five 24-hour periods prior to switching to twice daily dosing of caffeine and five 24-hour periods after switching to twice daily dosing of caffeine.

RESULTS

The median five-day average incidence of apnea and bradycardia during the once and twice daily dosing periods was 6.2 events and 6.4 events respectively (p=0.09).

CONCLUSIONS

There is little benefit of twice daily dosing of caffeine for apnea of prematurity.
