Timing of Umbilical Cord Clamping in Preterm Neonates: A Randomized Controlled Trial

Sudan Journal of Medical Sciences (SJMS) / Sudan JMS: Volume 19 (2024), Issue No. 2 / Pages 211–223

Abstract

Background: The optimal timing for clamping the umbilical cord remains controversial. This study aimed to assess the optimal timing of umbilical cord clamping and its effect on preterm neonates.


Methods: The study was a randomized controlled trial with the registration number: NCT06000800. It was conducted at Kasr Al Ainy Maternity Hospital, Cairo University Hospital, where a total of 80 pregnant women were randomly pooled and randomly divided into four groups with each group comprising 20 pregnant women. Umbilical cord clamping was performed in the first group immediately (5 sec after birth), after 30 sec in the second group, after 60 sec in the third group, and after 90 sec in the fourth group. After birth, clinical and laboratory parameters were assessed and recorded at the 1st, 6th, 12th, 24th, and 48th hours for all preterm neonates.


Results: Delayed cord clamping at 90 sec was linked to improved preterm neonatal outcomes including heart rate at the 1st and the 6th hours; respiratory rate at the 12th hour; oxygen saturation at the 1st hour; hemoglobin, hematocrit, and blood glucose levels at the 6th, 12th, 24th, and 48th hours; but also linked to increase in bilirubin levels at the 12th, 24th, and 48th hours (P < 0.001). There was no statistically significant difference concerning APGAR score; respiratory rate at the 12th hour, temperature at the 1st, 6th, 12th, 24th, and 48th hours; hemoglobin, hematocrit, and blood glucose at the 1st hour; and bilirubin at the 1st, 6th, and 12th hours in all groups (5, 30, 60, and 90 sec) (P > 0.05).


Conclusion: Better levels of blood glucose and hemoglobin were seen in preterm neonates whose cord clamping was delayed. Further studies should be carried out to determine the optimal timing of umbilical cord clamping with larger samples, for extended delay of clamping for more than 90 sec, and with recording of parameters for an extended period of follow-up even past the neonatal period.
