Abstract

Recording of blood pressure does not form a part of the routine examination in the neonatal period. This is
mainly due to the difficulties encountered in measuring blood pressure with the usual apparatus.
However, the Doppler apparatus is a light weight, battery-operated, portable instrument for measuring blood
pressures rapidly and accurately even by relatively inexperienced personel. The procedure is well tolerated by
nowborn infants.
In an attempt to measure blood pressure values in Korean newborn between 2 to 24 firs of life, blood pressure was taken on-.73 fullterm (male 39, female 34) from April I to October 30, 1981, at Chung-Ang Univ. Hospital & Sungae Hospital.
Additionally, blood pressure was cheked daily for 7 days in 18 cases of 73 subjects.
In all cases systolic blood pressure was recorded by the transcutaneous Doppler method, but diastolic blood pressure could not be obtained by the same method. Blood pressure measurments obtained with the Doppler method are compared with values representing the mean blood pressure obtained by the flush technique, palpation, and auscultation.
The results of this observation were as follows:
1. Mean systolic blood pressure showed 62.4±5.2 mmHg (Range: 52-78 mmHg) in the brachial artery, and 73.5±5.6 mmHg(Range: 62-94 mmHg) in the popliteal artery.
2. Statistically, brachial systolic blood pressure indicated a positive a correlation with popliteal systolic blood pressire.
3. There was no significant difference in systolic blood pressure between male & female.
4. Statistically, systolic blood pressure indicated a positive correlation with birth weight.
5. More or less steady rise in the systolic blood pressure day by day during the first week of life was noted. 6. Comparison of systolic blood pressure by Doppler method & other methods: The Doppler technique yields each 10.1mmHg, 11. 5mmHg, 13. 1mmHg higher mean systolic blood pressure values than the measurements obtained by the methods of flush, palpation, & auscultation. Statistically, blood pressure by Doppler method indicated a positive correlation with each blood pressure by other methods.
