Knowledge gaps in optimal umbilical cord management at birth

Area of Science:

• Neonatal Medicine
• Perinatal Research
• Pediatric Physiology

Background:

• The World Health Organisation recommends delayed umbilical cord clamping (at least one minute) for all newborns since 2014.
• Evidence supports placental transfusion benefits for all infants at birth.
• Optimal cord clamping duration and its impact on neonatal transition remain under investigation.

Purpose of the Study:

• To review the evidence supporting placental transfusion.
• To identify knowledge gaps regarding the newborn transition phase and blood volume.
• To propose research questions addressing optimal cord management and infant adaptation.

Main Methods:

• Literature review on placental transfusion and cord management.
• Analysis of the physiological transition of newborns.
• Identification of research needs based on current evidence and debates.

Main Results:

• Growing evidence supports the benefits of placental transfusion for all infants.
• The optimal timing for umbilical cord clamping is still debated.
• The effects of blood volume on neonatal adaptation require further study.

Conclusions:

• Further research is essential to determine optimal umbilical cord clamping protocols.
• Understanding the newborn's transition and the role of placental transfusion is crucial for improving neonatal care.
• Investigating parental perceptions is important for the successful conduct of clinical trials in this area.
