[Early mechanical respiration with prolonged inspiration in the treatment of acute respiratory insufficiency in the newborn]. / Ventilación mecánica temprana con inspiración prolongada, en el tratamiento de la insuficiencia respiratoria aguda del recién nacido.

The experience at the Servicio de Medicina Perinatal Pediátrica of the Centro Hospitalario "20 de Noviembre" of the ISSSTE is reported on the application of a ventilatory assistance criterion to treat the severe respiratory distress syndrome in the newborn. Early application of intermittent mechanical ventilation (IMV) is established to avoid clinical impairment. The mechanical ventilator is used in such a way that without withdrawing therapeutic effectiveness, it may cut down to a minimum complications derived from the use of IMV. The results show increase in survivorship, specially among the lower weight population and less complications than with the previous management method, in spite of a 70% increase in the use of IMV.

[Arterial pressure during the neonatal transitional period]. / Tensión arterial en el período de transición neonatal.

A total of 288 determinations of blood pressure were practiced in newborns using an ultrasonic unit with the purpose of establishing the blood pressure in the newborn during the neonatal transitional period in a sampling cycle divided into four stages (0:30, 4:00, 6:00 and 10:00 hours). The results were analyzed in a descriptive fashion by means of variation indexes that show the changes occurred in B.P. between one and the other stages of the sampling cycle.
