本文提出无心肺疾病早产儿经皮氧分压(TcPO_2)和经皮氧饱和度(TcSO_2)的正常值,并研究了孕龄、日龄和觉醒状态对经皮测氧的影响。对28例(男15,女13),出生体重为1.04～3.06kg(1.82±0.58kg),平均孕周324w(29～36w)的婴儿进行监测。早产儿在达到足月前每隔三周,以后间隔6周、3月、6月和12月,白天进行监测觉醒状态、喂奶和睡眠状态的TePO_2、TcSO_2、呼吸形式。监测前每个婴儿都测体重和身长。 This paper presents the normal values ​​of percutaneous oxygen pressure (TcPO_2) and percutaneous oxygen saturation (TcSO_2) in preterm infants without heart and lung disease, and studies the effects of gestational age, age and wakefulness on percutaneous oxygenation. 28 infants (15 males and 13 females), infants with a birth weight of 1.04-3.06 kg (1.82 ± 0.58 kg) and an average gestational age of 324 weeks (29-36 weeks) were monitored. Preterm infants are monitored for awake, feeding, and sleeping TePO_2, TcSO_2, and respiratory forms during the third trimester, up to six weeks, three months, six months, and twelve months after reaching full term. Each baby was monitored for weight and length before monitoring.
