这项研究评估了 ELBW 婴儿出生后 12 小时内体温下降时的外周血管收缩情况。一项针对 10 名 ELBW 婴儿的探索性受试者内设计。每分钟测量腹部和足部温度。还评估了外周血管收缩（腹部>外周温度2°C）和腹部-外周温差。每个婴儿的腹部温度和周围温度显着相关。一名 880 克的婴儿表现出孤立的外周血管收缩；体重 960 克的婴儿腹部温度比周围温度高出 1°C 以上。八名较小的婴儿没有表现出外周血管收缩，并且在大部分观察中外周温度高于腹部温度。在 8 名婴儿中，当腹部温度低于 36.5°C 时，平均温差显着较高。尽管气温较低，但大多数 ELBW 婴儿在出生后的前 12 小时内并未表现出外周血管收缩。 ELBW婴儿在此期间的血管舒缩控制可能还不成熟。
This study evaluated peripheral vasoconstriction in ELBW infants when body temperature decreased during the first 12-hours of life. An exploratory, within-subjects design with 10 ELBW infants. Abdominal and foot temperatures were measured every minute. Peripheral vasoconstriction (abdominal > peripheral temperature by 2° C) and abdominal-peripheral temperature difference were also evaluated. Abdominal and peripheral temperatures were significantly correlated within each infant. One 880 g infant exhibited isolated peripheral vasoconstriction; a 960 g infant had abdominal temperatures more than 1° C higher than peripheral temperatures. Eight smaller infants exhibited no peripheral vasoconstriction and spent most of their observations with peripheral greater than abdominal temperatures. In 8 infants, mean temperature difference was significantly higher when abdominal temperature was less than 36.5° C. Most ELBW infants did not exhibit peripheral vasoconstriction during their first 12-hours of life, despite low temperatures. ELBW infants’ vasomotor control may be immature during this period.
