Abstract

Objective

To determine whether there were immediate adverse effects of an umbilical artery pH Study design

All infants triaged to the newborn nursery with an umbilical artery pH Results

Acidemic and control groups were similar for pregnancy complications before labor, but acidemic infants were more often delivered by cesarean section (20/35 vs 6/35, p = 0.001). No differences existed between acidemic and control infants in gestational age, birth weight, neurologic evaluations, hearing deficits, feeding tolerance, and hepatic function. The acidemic group had a higher mean serum creatinine than control infants on day 2 of life (0.90 +/- 0.34 vs 0.71 +/- 0.12 mg/dl, p = 0.005) and a greater number of infants with a urine Chemstrip positive for heme (14/35 vs 3/35, p = 0.005). No differences existed between groups in time to first void, urine specific gravity, and number of infants with microscopic hematuria.

Conclusion

Term and near-term infants born with an umbilical artery pH
