Resuscitative procedures at birth in late preterm infants

Abstract

Objective: Evaluate the need for resuscitative procedures at birth, in late prematures.

Study design: This prospective cohort study enrolled all liveborn infants from 1 to 30 September 2003, with 34 to 41 weeks of gestation without congenital anomalies, born in 35 public hospitals of 20 Brazilian state capitals. Logistic regression analyzed variables associated with the need for bag and mask ventilation.

Result: Of the 10 774 infants studied, 1054 were late preterms and 485 required resuscitative measures. Of the 1054, 338 (32%) received only free-flow oxygen, 143 (14%) were bag and mask ventilated, 27 (3%) were intubated and 10/27 received chest compressions and/or medications. Bag and mask ventilation in late preterms was associated with twin gestation, maternal hypertension, nonvertex presentation, cesarean delivery and lower gestational age.

Conclusion: Improving control of maternal hypertension, prolonging gestation for 1 to 2 weeks and restricting operative deliveries could decrease the need of resuscitation of late preterms at birth.
