Reference values and associated factors for Japanese newborns’ blood pressure and pulse rate

Abstract

The present study is the first to show the distributions of Asian newborns' BP levels and pulse rate. The assessment of newborns' BP levels and pulse rate should consider birth weight, gestational age after birth, and actual condition at BP measurement.

Neonatal hypertension: cases, causes, and clinical approach

“…BP be most accurate in a quiet, resting infant and higher in those who are crying, however other activities such as feeding or even non-nutritive sucking may increase BP as well (figure 2). [51,52] Consistent measurement technique is essential to obtain accurate BP values. Standardized protocols for measurement of BP are available [53,54] and help to ensure that accurate BP values are obtained to guide clinical decision making.…”

“…In contrast to the previous studies, our study conducted an exhaustive systematic search for population-based centiles in all ages and compared them with a large sample of cut-offs for hypotension that are widely used in clinical practice. Our study identified only two studies that provided blood pressure centiles in children < 1 year including one study in new-borns and one at age of 6 months [17, 24]. Therefore, more studies providing reference values of blood pressure in children < 1 year are required.…”
