1851年,Gerlach首先证实了人的皮肤能不断地吸收氧气,排泄二氧化碳。对成人已作过大量的研究。估计呼吸的1～2％是经过皮肤的。但是,没有对新生儿经皮气体交换作过直接测定。作者应用皮肤细胞测量气体交换,对27例新生儿(出生体重0.96到4.43公斤,胎龄27到40周)分成三个胎龄组:37周到足月儿(12例),31到36周(8例),27到30周(7例),进行了经皮呼吸的研究。结果足月儿经皮气体交换速度比成人慢。在空气中,足月儿氧吸收及二氧化碳排泄平均为32.0±8.7、40.5±22.4ml/m~2/h,成人为62±9.4、86.5±12.8ml/m~2/h。在高浓度氧中,足月儿对氧的吸收速度也比成人慢。胎龄<31周的婴儿,在新生儿
In 1851, Gerlach first confirmed that human skin can continuously absorb oxygen and excrete carbon dioxide. Much research has been done on adults. It is estimated that 1 to 2% of the breath is through the skin. However, no direct determination of percutaneous gas exchange in newborns was made. The authors used skin cells to measure gas exchange and divided 27 newborns (birth weight 0.96 to 4.43 kg, gestational age 27 to 40 weeks) into three groups of gestational age: 37 weeks to full-term infants (12), 31 to 36 weeks 8 cases), 27 to 30 weeks (7 cases), the study of percutaneous respiration. Results full-term children percutaneous gas exchange slower than adults. In air, the mean term oxygen absorption and carbon dioxide excretion were 32.0 ± 8.7,40.5 ± 22.4ml / m ~ 2 / h in adults and 62 ± 9.4,86.5 ± 12.8ml / m ~ 2 / h in adults. In high concentrations of oxygen, term infants oxygen absorption rate slower than adults. Baby <31 weeks of age in newborns
