Oscillometric blood pressure reference values of African full-term neonates in their first days postpartum.

Sadoh WE, Ibhanesebhor SE - Cardiovasc J Afr (2009 Nov-Dec)

Bottom Line: The day 1 SBP of babies > 4 kg were significantly higher than those who weighed < 2.5 and 2.5-4 kg (p = 0.01, p = 0.05), respectively.This study provided current normative SBP, DBP and MAP values for Nigerian neonates.The BP readings compared with their Caucasian counterparts.

ABSTRACT

Background: Knowing the normative blood pressure (BP) in a newborn baby is important in order to identify abnormal BP readings. This study was done to determine normative BP values of Nigerian newborns, using the 8100 Dinamap monitor.

Methods: Consecutive full-term neonates delivered in a tertiary centre in Nigeria were recruited for the study. The babies' systolic (SBP), diastolic (DBP) and mean arterial (MAP) blood pressures were measured within the first four days after birth.

Results: A total of 473 babies were recruited for the study. The mean SBP, DBP and MAP readings on day 1 were 66.8 +/- 7.7, 38.5 +/- 6.3 and 47.9 +/- 6.3 mmHg, respectively. The day 1 SBP of babies > 4 kg were significantly higher than those who weighed < 2.5 and 2.5-4 kg (p = 0.01, p = 0.05), respectively.

Conclusion: This study provided current normative SBP, DBP and MAP values for Nigerian neonates. The BP readings compared with their Caucasian counterparts.

Figure 2: The distribution of fifth, 50th and 95th percentiles of SBP, DBP and MAP of one-day-old neonates.

Mentions: Since there was no statistically significant difference in SBP, DBP and MAP from day 2 to 4, these values were further analysed together as a group in comparison with day 1. The mean SBP of the group was 69.2 ± 8.3 (range: 48–108) mmHg, the mean DBP was 40.4 ± 6.8 (25–68) mmHg and the mean MAP was 50.0 ± 6.9 (33–78) mmHg. The fifth, 50th and 95th percentiles for SBP, DBP and MAP measured on day 1 and days 2 to 4 are shown in Figs 2 and 3.
