摘　　要：目的探讨正常足月新生儿7 d内血压的正常值范围及每日变化,研究早期新生儿血压临界值。方法应用美国Omni-TrakTMNVS型监护仪上的DINAMAP测压装置,随机检查50例足月新生儿生后7 d内的血压值。测量右上臂血压,记录收缩压(SBP)、舒张压(DBP)和平均动脉压(MAP)数值。结果1)日龄(X1)对正常足月新生儿SBP、DBP、MAP有非常显著的影响。2)SBP、DBP、MAP与X1、出生体质量(X2)、胎龄(X3)回归方程分别为SBP=32.4+0.7X1+3.7X2+0.6X3(mm Hg),DBP=13.1+0.6X1+2.9X2+0.6X3(mm Hg),MAP=17.3+0.4X1+2.0X2+0.8X3(mm Hg),MAP=DBP+0.45(SBP-DBP)(mm Hg)。3)7 d内不同胎龄、不同出生体质量新生儿DBP、SBP、MAP不同。正常足月新生儿高血压临界值分别为SBP>90 mm Hg,DBP>65 mm Hg,MAP>75 mm Hg。4)低血压临界值分别为:SBP<50 mm Hg,DBP<30 mm Hg,MAP<40 mm Hg。结论明确新生儿7 d内血压范围及血压临界值为新生儿高血压或(和)低血压诊断提供了可靠的依据。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 regreasion equations were built respectively. SBP = 32.4 ＋ 0.7X1 ＋ 3.7 X2＋0.6X3（mm H.g）, DBP = 13.1＋ 0.6X1 ＋ 2, 9X2 ＋ 0.6X3（mmHg）. MAP= 17.3 ＋ 0,4X1 ＋ 2.4X2 ＋ 0, 8X3（mmHg）. 3. MAP=DBP＋ 0.45（SBP- DBP）（mm Hg）, 4. The critical hypertension and hypotension in newborn infants were obtained. Conclusions During the first 7 days of life, there is a prngres,sive 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 gestationsl age, The critical hypertension and hypotension in newborn infants is important for clinic diagnosis.
