Objective:
To establish the normative blood pressure (BP) values in healthy Indian neonates using oscillometric method, and to develop BP percentile charts.
Design:
Prospective observational study.
Setting:
Neonatal unit of a teaching hospital in Eastern India.
Participants:
1617 hemodynamically stable inborn neonates without birth asphyxia, major congenital anomaly, maternal complications (e.g. preeclampsia, hypertension, diabetes) or critical neonatal illness.
Procedure:
Quite state measurements of systolic BP (SBP), diastolic BP (DBP) and mean arterial pressure (MAP) were recorded by oscillometric method on day 4, 7 and 14 of postnatal life. The averages of three readings at 2-minute intervals were used.
Results:
Percentile charts (providing 5th, 10th, 25th, 50th, 75th, 95th, and 99th percentile values) have been developed. SBP, DBP and MAP showed a steady rise from day 4 to day 14, and were comparable between males and females, but were significantly lower in preterms than in term neonates.
Conclusions:
Normative neonatal BP data along with gestational age-wise percentile charts shall be of help for decision-making and planning for sick newborns.

01:30Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
