[Cardiorespirographic parameters in the first 12 hours of life. Influence of the administration of thiopental and diazepam plus thiopental on labor].

Cardiorespirographic parameters undergo a series of evolutionary modifications during first hours of life, becoming stable between the sixth and twelfth. The authors analyse how these parameters are influenced by the administration to the mother of thiopental and diazepam plus thiopental during birth. They observed a significant reduction, during the first hour after birth, in the range and frequency of accelerations in the newborn babies whose mothers had been administered one of the drugs. Also, they observed a greater number of cases of decelerations in the newborns who were given drugs. No significant differences were observed in other parameters, and after the twelfth hour no differences were observed at all.
