The timing of the umbilical cord clamping at birth is still controversial. In the modern era of medicine, the cord has been clamped early to facilitate resuscitation and stabilization of infants. However, recently delayed cord clamping has been supported by physicians because it allows for the physiological transfer of blood from the placenta to the infant. Many clinical studies have revealed that the delayed cord clamping elevates blood volume and haemoglobin and prevents anaemia in infants. Moreover, since it was known that umbilical cord blood contains various valuable stem cells such as haematopoietic stem cells, endothelial cell precursors, mesenchymal progenitors and multipotent/pluripotent lineage stem cells, the merit of delayed cord clamping has been magnified. In this review, we discuss the advantages and disadvantages of delayed cord clamping at birth. We highlight the importance of delayed cord clamping in realizing mankind’s first stem cell transfer and propose that it should be encouraged in normal births.

Introducción y objetivos: El tratamiento de reperfusión en un síndrome coronario agudo con elevación del segmento ST (SCACEST) se puede realizar con agentes fibrinolíticos o con angioplastia primaria (ICPp). La ICPp es la estrategia de elección, pero muchos de los pacientes con SCACEST acuden inicialmente a hospitales sin ICPp. Se han desarrollado programas de asistencia al SCACEST en los que se integran ambos tratamientos, utilizando la trombolisis en casos indicados, seguida de un estudio angiográfico (estrategia farmacoinvasiva). El objetivo del estudio es analizar los resultados del tratamiento del SCACEST según sea diagnosticado en áreas de salud con o sin disponibilidad de ICPp inmediata.
