[Monitoring of oxygenation in pediatric anesthesia].

The monitoring of oxygenation during anaesthesia is aimed at protecting patient. This is particularly important in the case of young children and infants for whom hypoxy and hyperoxy are very serious risks. The purpose of the study is to compare the respective advantages and disadvantages of the 2 types of non-invasive oxygenation: transcutaneous estimation of PO2 (PtcO2) and pulse oxymetry (SaO2). Results point to the superiority of pulse oxymetry except in surgery on newly-born babies.
