Abstract

Measurement of blood pressure in neonate is an important diagnostic procedure. But measurement of blood pressure were not performed routinely because of difficulty in measuring blood pressure and variable normal range according to measuring apparatus. Recently some accurate and convinient apparatuses of measuring blood pressure have been introduced in neonatal care, so normal blood pressure values of neonate are needed. In this study, we establish the normal range of blood pressure in neonates and compared the right and left upper extremity, and upper and lower extremity blood pressures. We examined 300 newborns, aging one day to seven day, delivered in Severance Hospital using two oscillometric device. The results could be summerized as the followings: 1) Mean values of systolic pressure measurements were as follows: Rt. upper extremity, 73.1 ±7.7 mmHg (range 54.3—97.0 mmHg); Lt. upper extremity, 71.8 ±7.2 mmHg (range 49.3—96.0 mmHg); Lt. lower extremity, 75.7±8.2 mmHg (range 52.0—99.0 mmHg). Mean values of diastolic pressure were as follows: Rt. upper extremity, 42.4 ±7.4 mmHg (range 25. 3—68.7 mmHg); Lt. upper extremity, 42.9±7.1 mmHg (range 24.0—69.0 mmHg); Lt. lower extremity, 41.8 ±6.2 mmHg (range 28.0—63.0 mmHg). 2) Daily measurement of systolic, diastolic and mean pressures of four limbs showed steady rise during first week of life. 3) Systolic, diastolic and mean pressures between Rt. and Lt. upper extremity showed no significant difference. 4) Systolic pressures of lower extremities were significantly higher than upper extremities, but in diastolic and mean pressures there were no significant difference between upper and lower extrem- ities.
