Andersson and colleagues conducted a randomized clinical trial of resuscitation with early cord clamping or resuscitation with an intact umbilical cord in late-preterm and term infants born by vaginal delivery and not breathing at 30s after birth. Nurse-midwives trained in Helping Babies Breathe (HBB – © American Academy of Pediatrics) conducted the trial. The benefits of an intact umbilical cord for at least 180s (identified by *) included higher preductal pulse oximetry (SpO2) and Apgar scores at 1, 5 and 10 min after birth and lower heart rate at 1 and 5 min. Delayed cord clamping also resulted in earlier cry/breathing. Body temperature after resuscitation and transcutaneous bilirubin at discharge were similar between early and delayed cord clamping groups.
