Three groups of neonates were observed during their first 5 days of postnatal life. Healthy term babies (N = 22) did not differ in their heart rate variability (HRV) nor heart rate (HR) from the healthy preterm babies (N = 21) during the first 3 days. On day 5 beat-to-beat variability of term babies was greater. In healthy term and preterm infants HRV increased between days 1 and 3. HRV of the babies with respiratory distress syndrome (RDS) (N = 1) remained low throughout the study period. HR of the babies with RDS was significantly higher compared to the other groups on the days 1 and 3. Transcutaneous PO2 was high in healthy preterm infants compared to the other groups. The correlation between PaCO2 and PtcO2 in RDS was insufficient to make clinical judgement. PtcCO2 of all neonates tended to rise on the day 5 but the rise was most prominent in the infants with RDS. The correlation of PaCO2 and PtcCO2 was good. In RDS high HR, low HRV and elevated PtcCO2 were the typical findings and present throughout the study period.
在出生后的头5天观察了三组新生儿。健康足月儿（N = 22）在出生后头3天的心率变异性（HRV）和心率（HR）与健康早产儿（N = 21）没有差异。在第5天，足月儿的逐搏变异性更大。在健康足月儿和早产儿中，HRV在第1天至第3天之间增加。患有呼吸窘迫综合征（RDS）的婴儿（N = 1）在整个研究期间HRV一直较低。在第1天和第3天，患有RDS的婴儿的HR明显高于其他组。与其他组相比，健康早产儿的经皮PO2较高。RDS中PaCO2与PtcO2之间的相关性不足以做出临床判断。所有新生儿的PtcCO2在第5天趋于升高，但在患有RDS的婴儿中升高最为明显。PaCO2与PtcCO2的相关性良好。在RDS中，高HR、低HRV和升高的PtcCO2是典型表现，且在整个研究期间都存在。
