Background: In the range of timing suggested by American College of Obstetricians and Gynecologists 30 to 60 s, preterm Wants may potentially derive more short and long-term benefits with delayed cord clamping (DCC) for at least 60 s. However, there are concerns with longer resuscitation delay in this vulnerable population.& para;& para;Objective: To compare the clinical consequences of 45 versus 60 s delay in umbilical cord clamping in singleton infants born between 23(0/7) to 31(6/7) weeks gestation.& para;& para;Study design: We implemented DCC process in very preterm singleton infants, initially for 45 s and later, modified the policy to increase the delay to 60 s. We compared the infants born and received DCC (n = 60) during the 45 s study period (DCC-45 cohort), from Aug.19, 2013, to Aug.18, 2014 to the infants born and received DCC (n = 63) during the 60 s study period (DCC-60 cohort), from Feb.1, 2015, to Jan.31, 2016.& para;& para;Results: The incidence of necrotizing enterocolitis in DCC-60 cohort was 0% compared to 8% in the DCC-45 cohort (P = 0.02). Similarly, incidence of culture-positive sepsis was significantly lower in the DCC-60 cohort compared to DCC-45 cohort (8% versus 18%; P = 0.04). Incidence of mortality and other major morbidities were similar between both groups. Length of stay was significantly lower in DCC-60 cohort compared to DCC-45 cohort.& para;& para;Conclusion: DCC for 60 s in very preterm singleton infants was safe, feasible and not associated with any adverse maternal or neonatal short-term outcomes compared to DCC for 45 s.
