Abstract:
Objective To study the normal values of blood pressure in healthy full-term infants in the first 7 days of life,and to determine the critical hypertension and hypotension in newborn infants.Methods Omni-Trak~(TM)NVS monitor with DINAMAP was used to measure the blood pressure.Systolic,diastolic and mean blood pressure were measured every day by DLNAMAP in a cohort of 50 healthy full-term infants in the first 7 days of life.Results 1.Systolic,diastolic and mean blood pressure of healthy full-term infants were significantly influenced with the age of birth.2.Stepwise linear multiple regressions was used to examine the multiple correlations among days of life,birth weight and gestational age.3.Optimal regression equations were built respectively.SBP=32.4+0.7X_1+(3.7X_2+)(0.6)X_3(mm Hg).DBP=13.1+ 0.6X_1+2.9X_2+0.6X_3(mm Hg).MAP=17.3+0.4X_1+2.4X_2+0.8X_3(mm Hg).(3.MAP=)(DBP+)(0.45)(SBP-DBP)(mm Hg).4.The critical hypertension and hypotension in newborn infants were obtained.Conclusions (Du)ring the first 7 days of life,there is a progressive rise in blood pressure of healthy full-term infants.There are linear reliance correlations between systolic,diastolic,mean blood pressure and day of life,birth weight gestational age.The critical hypertension and hypotension in newborn infants is important for clinic diagnosis.
