Total peripheral blood flow and blood flow through the skin and muscle were measured in the calf with an electrocapacitance plethysmograph with counter pressure in a group of 62 "well" newborn infants (birth weight, less than 3500 g). Blood pressure in the contralateral leg was measured with an Arteriosonde 1010, and peripheral vascular resistance was calculated as mean blood pressure (mm Hg) divided by blood flow (ml per 100 ml tissue per min). The results show that total peripheral blood flow and blood flow through he skin and muscle correlated inversely with increasing birth weight and gestational age. Postnatally, total blood flow and blood flow through the skin and muscle decreased gradually during the first 7 days of life and in the rest of the neonatal period. Peripheral vascular resistance and resistance in the skin and muscle correlated directly with increasing birth weight and gestational age. Postnatally, peripheral vascular resistance and resistance in the skin and muscle increased during the first 7 days of life and the neonatal period.
使用带有反压的电容式体积描记器，对62名“健康”新生儿（出生体重小于3500克）的小腿进行了总外周血流量以及通过皮肤和肌肉的血流量测量。使用动脉超声仪1010测量对侧腿部的血压，并将外周血管阻力计算为平均血压（毫米汞柱）除以血流量（每分钟每100毫升组织的毫升数）。结果表明，总外周血流量以及通过皮肤和肌肉的血流量与出生体重和胎龄的增加呈负相关。出生后，在生命的前7天以及新生儿期的其余时间，总血流量以及通过皮肤和肌肉的血流量逐渐减少。外周血管阻力以及皮肤和肌肉的阻力与出生体重和胎龄的增加呈正相关。出生后，外周血管阻力以及皮肤和肌肉的阻力在生命的前7天以及新生儿期增加。
