Delivery room blood pressure percentiles of healthy, singleton, liveborn neonates

Pediatrics International, 04/26/2012

Salihoglu O et al. – Data presented in this study include sex– and delivery–mode–specific blood pressure (BP) percentile curves using an oscillometric method and serve as a valuable reference for physicians in dealing with the management of singleton, liveborn late preterm and term newborns in the delivery room intensive care.

Methods

  • BP measurements were taken after birth in supine-positioned neonates in the delivery room using an oscillometric device.
  • A total of 982 well-nourished neonates who did not require resuscitation, were not fetally malnourished, were not admitted to the neonatal intensive care unit and were without obvious congenital abnormalities were included in the study.

Results

  • Sex- and type-of-delivery-specific 5th and 95th percentiles BP measurements were obtained for gestation.
  • Mean BP values for systolic, diastolic and mean of term neonates were 63.98 ± 12.29 mmHg, 38.34 ± 11.06 mmHg and 49.32 ± 11.33 mmHg, and late preterm neonates were 61.80 ± 12.46 mmHg, 33.17 ± 9.97 mmHg and 46.52 ± 10.8 mmHg, respectively.
  • There were weak but significant correlations between birthweight, birth length and head circumference and systolic, diastolic and mean arterial BP values (r = 0.20, r = 0.15 and r = 0.20, respectively, P < 0.001).
  • Neonates who were delivered vaginally had higher mean BP values for systolic, diastolic and mean than neonates delivered by cesarean section (P < 0.05).
  • Female neonates had higher systolic BP values than male neonates (P < 0.05).
