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.
