RESUMEN
Umbilical cord clamping practices impact nearly 140 million births each year. Current evidence has led professional organizations to recommend delayed cord clamping (DCC), as opposed to early cord clamping (ECC), as the standard of care in uncomplicated term and preterm deliveries. However, variability remains in cord management practices for maternal-infant dyads at higher risk of complications. This review examines the current state of evidence on the outcomes of at-risk infant populations receiving differing umbilical cord management strategies. Review of contemporary literature demonstrates members of high-risk neonatal groups, including those affected by small for gestational age (SGA) classification, intrauterine growth restriction (IUGR), maternal diabetes, and Rh-isoimmunization, are frequently excluded from participation in clinical trials of cord clamping strategies. Furthermore, when these populations are included, outcomes are often underreported. Consequently, evidence regarding optimal umbilical cord management in at-risk groups is limited, and further research is needed to guide best clinical practice.
