Why the study?
Do different PO2 monitoring techniques (intra-vascular, transcutaneous, capillary) accurately correlate with aortic sample values in newborn infants?
Do different PO2 monitoring techniques (intra-vascular, transcutaneous, capillary) accurately correlate with aortic sample values in newborn infants?
Transcutaneous monitoring is the most reliable and cost-effective method for PO2 monitoring in newborn infants compared to intra-vascular electrodes and capillary samples.
Transcutaneous PO2 monitoring may be reliable and cost-effective in newborns; cross-sectional data leaves open need for randomized validation.
This study is an evaluation of different methods of Po2 monitoring in newborn infants. These were an intra‐vascular Pb2 electrode (Searle Life Support Systems); transcutaneous monitoring (Kontron and Hewlett‐Packard); and arteriatized capillary blood samples. Values of each were compared with simultaneous aortic sample values and their correlation compared. The Searle electrode and TCM were found to be of equivalent accuracy overall, although the Searle was less reliable. Searle catheters were more difficult to insert than normal catheters, with a high wastage. Arterialized capillary Po2 values did not correlate with arterial. Transcutaneous monitoring is the most reliable and cheapest method.
