Significance of grunting respirations in infants admitted to a well-baby nursery

Objectives: (1) To determine the frequency and duration of grunting in term and near-term newborns; (2) to determine the peripartum characteristics as sociated with grunting; and (3) to compare the short-term outcomes of newbo rns with and without grunting. Design: Medical record review of all newborns admitted to a well-baby nurse ry during a 2-month period. Setting: University well-baby nursery for term infants, with more than 2700 deliveries annually. Main Outcome Measures: Frequency and duration of grunting, maternal and new born clinical characteristics, clinical course, and length of stay. Results: Grunting respirations beginning during the first 4 hours of life w ere recorded for 81 (17.4%) of 466 newborns. Fifty-five (68%) stopped grunt ing within 30 minutes of birth, 69 (85%) by 1 hour, and 75 (93%) by 2 hours . More mothers of grunting infants received intrapartum antibiotics than mo thers of nongrunters (33% vs 20%; P=.03), More grunting infants than nongru nters received bag and mask resuscitation (15% vs 5%; P=.01). More chest ra diographs, blood cell counts, and blood cultures were ordered for grunting infants, and antibiotics were more often given to grunting than nongrunting infants (11.1% vs 4.6%; P=.04). Grunters' length of stay exceeded that of nongrunters (72 vs 55 hours; P=.01), but only 3 were transferred to a neona tal intensive care unit. Conclusions: All grunting infants should be carefully observed, but because nearly all otherwise healthy term or near-term infants will stop grunting and have a benign course, other interventions can be postponed for 1 or 2 h ours to give the newborn a chance to stop grunting or show other signs of r espiratory illness.
