Is a standard protocol necessary for oscillometric blood pressure measurement in term newborns?
OBJECTIVE
The necessity of taking only one randomized blood pressure measurement or averaging three repeated measurements and, the effects of various stages of the restful state and body position on blood pressure measurements obtained with the oscillometric technique were investigated in 138 healthy term newborns.


METHODS
The Athena oscillometer was used to measure blood pressure. Three successive measurements with a 5-min interval were made in each of two positions, prone and supine, in random order 30 min after the last feeding if newborns were in very quiet or quiet sleep. During routine recording of vital signs, another (single) measurement was obtained before feeding the infant regardless of the body position of the newborn, provided that they were not struggling, crying or moving.


RESULTS
For all systolic, diastolic and mean blood pressures measured, there were no significant differences among either prone, supine and single measurements or among three successive measurements in each position.


CONCLUSIONS
We conclude that, in the routine care of term newborns, blood pressure measurements with the oscillometric technique may be made without the need of a special position or sleep state, provided that the measurements are made with an appropriate sized cuff in the absence of struggling, crying and movement of the newborn. Taking only one randomized measurement under these conditions would be enough and practical in daily newborn care practice instead of repeating and averaging many measurements.
