[The cardiorespirogram in the first 12 hours of life. Relation to the form of termination of labor]. / Estudio del cardiorrespirograma en las primeras doce horas de vida. Relación con la forma de terminación del parto.

Cardiorespirography is a method of monitoring which establishes a correlation between cardiac and respiratory activity. During the first twelve hours following birth cardiorespirographic parameters undergo a series of evolutionary modifications, becoming stable between the sixth and twelfth hours. Authors analyse how the manner in which birth is terminated influences parameters during first twelve hours. In the case of caesarean births they find only one instance of diminishing accelerations during the first hour, and in spontaneous births, a reduced number of instances of decelerations are registered during first and sixth hour. They believe that these findings are due to drugs administered during birth rather than to the manner in which this was achieved.
