ABSTRACT
OBJECTIVE: Nasal continuous positive airway pressure (NCPAP) is frequently used for prolonged periods in very low birth weight infants. We asked if NCPAP affects gastric emptying. STUDY DESIGN: Preterm newborn infants (n = 16) with a mean body weight of 935 g (SD, 155) and a mean gestational age of 27.7 weeks (SD, 1.9) were treated with NCPAP and fed by orogastric tube. A comparison group of 20 newborn infants with a mean body weight of 1090 grams (SD, 130) and a mean gestational age of 28.2 weeks (SD, 1.2) were not receiving NCPAP. All newborn infants received a milk formula containing 81 kcal/dL given in similar quantities. The antral cross-sectional area was measured by means of an ultrasound technique. RESULTS: Mean half-time of antral cross-sectional area was 28 minutes (SD, 12) in the NCPAP group and 40 minutes (SD, 17) in the comparison group ( P < .05). There were no differences in gastrointestinal complications between the two groups. CONCLUSIONS: The gastric emptying time was shorter for newborn infants treated with NCPAP.
