The changes in transcutaneous oxygen tension (TcPO2) during 123 observations of 10 care procedures were compared with the intrinsic variability of the TcPO2 at the time of the procedures. Standard deviations of the TcPO2 were measured by planimetry from continuous recording in undisturbed infants during a 10-minute control period immediately before each procedure. The decrement of TcPO2 during the procedure and the change in TcPO2 5 minutes after the procedure had ended were measured. A chest x-ray film had the most striking early hypoxic effect, but all the procedures produced early hypoxia in at least one-quarter of the infants. The significant decreases in oxygenation with particular procedures indicate areas in which changes in techniques might be applied to the benefit of the neonate.
在对10项护理操作进行的123次观察中,将经皮氧分压(TcPO2)的变化与操作时TcPO2的内在变异性进行了比较。在每次操作前10分钟的对照期内,通过平面测量法从未受干扰的婴儿连续记录中测量TcPO2的标准差。测量了操作过程中TcPO2的下降以及操作结束后5分钟时TcPO2的变化。胸部X光片具有最显著的早期缺氧效应,但所有操作在至少四分之一的婴儿中都产生了早期缺氧。特定操作中氧合的显著下降表明,在这些领域中改变技术可能会对新生儿有益。
