Delayed umbilical cord clamping - benefits and risks.

Area of Science:

• Obstetrics and Gynecology
• Neonatal Medicine
• Perinatal Care

Background:

• Delayed umbilical cord clamping is a common method for managing the third stage of labor.
• Benefits are observed with delays exceeding 30 seconds, with one minute being a typical recommendation.
• This practice is crucial for optimizing neonatal outcomes.

Purpose of the Study:

• To summarize the benefits of delayed umbilical cord clamping.
• To highlight the positive impact on infant iron reserves and development.
• To review the safety profile regarding maternal blood loss.

Main Methods:

• Review of existing literature and clinical guidelines on delayed umbilical cord clamping.
• Analysis of reported outcomes, including neonatal iron status, necrotizing enterocolitis, and intraventricular hemorrhage.
• Assessment of maternal and neonatal safety parameters, particularly blood loss.

Main Results:

• Delayed clamping (around 1 minute) increases infant iron reserves, supporting development.
• Reduced incidence of necrotizing enterocolitis and intraventricular hemorrhage in preterm infants.
• No increase in maternal blood loss observed, even in multiple pregnancies or C-sections.

Conclusions:

• Delayed umbilical cord clamping is beneficial for neonatal iron status and may reduce risks of severe neonatal morbidities.
• The practice is safe for mothers, with no evidence of increased blood loss.
• A delay of approximately one minute is recommended for optimal benefits.
