However, the effects of longer durations of cord clamping with respiratory support are unknown.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To determine whether resuscitating preterm newborns while keeping the placental circulation intact and clamping the cord after a long delay would improve outcomes compared with umbilical cord milking.<\/jats:p>\n <\/jats:sec>\n \n Design, Setting, and Participants<\/jats:title>\n This randomized clinical trial (PCI Trial) was conducted at 8 Italian neonatal intensive care units from April 2016 through February 2023 and enrolled preterm newborns born between 23 weeks 0 days and 29 weeks 6 days of gestation from singleton pregnancies.<\/jats:p>\n <\/jats:sec>\n \n Interventions<\/jats:title>\n Enrolled newborns were randomly allocated to receive at-birth resuscitation with intact placental circulation for 180 seconds or umbilical cord milking followed by an early cord clamping (within 20 seconds of life).<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n The primary outcome was the composite end point of death, grade 3 to 4 intraventricular hemorrhage, and bronchopulmonary dysplasia at 36 weeks of postconception age. Prespecified secondary end points were the single components of the composite primary outcome. An intention-to-treat analysis was conducted.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Of 212 mother-newborn dyads who were randomized, 209 (median [IQR] gestational age, 27 [26-28] weeks; median [IQR] birth weight, 900 [700-1070] g) were enrolled in the intention-to-treat population; 105 were randomized to the placental circulation intact group, and 104 were randomized to the cord milking group. The composite outcome of death, grade 3 to 4 intraventricular hemorrhage, or bronchopulmonary dysplasia occurred in 35 of 105 newborns (33%) in the placental circulation intact group vs 39 of 104 newborns (38%) in the cord milking group (odds ratio, 0.83; 95% CI, 0.47-1.47;\n P<\/jats:italic>\n \u2009=\u2009.53).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n In a randomized clinical trial of preterm newborns at 23 to 29 weeks\u2019 gestational age, intact placental resuscitation for 3 minutes did not lower the composite outcome of death, grade 3 to 4 intraventricular hemorrhage, or bronchopulmonary dysplasia compared with umbilical cord milking.<\/jats:p>\n <\/jats:sec>\n \n Trial Registration<\/jats:title>\n \n Clinicaltrials.gov Identifier:\n
