Abstract

OBJECTIVE:

To determine if an expiratory flow increase technique (EFIT) is associated with acid reflux episodes in infants born preterm with bronchopulmonary dysplasia (BPD).

METHODS:

A crossover study was carried out. Eighteen subjects divided into 2 groups were randomly assigned to receive 2 EFIT sessions at 2 postprandial time points. Group 1 started 2 hours after feeding and group 2 started 3 hours after feeding. Esophageal acid exposure was assessed by the reflux index (RI) during EFIT and 20 minutes before EFIT by esophageal pH monitoring.

RESULTS:

A significant reduction in the RI was observed in group 1 with EFIT performed 2 hours after feeding. Group 2 showed no significant differences in RI values before and during EFIT in both postprandial periods.

CONCLUSION:

When EFIT is performed 2 and 3 hours after feeding, it is not associated with an increase in acid reflux episodes in infants born preterm with BPD.
