Abstract

Objective: To assess whether end tidal capnography (EtCO2) monitoring reduced the magnitude of difference in carbon dioxide (CO2) levels and the number of blood gases in ventilated infants.
Study design: A case control study of a prospective cohort (n=36) with capnography monitoring and matched historical controls (n=36)
Result: The infants had a median gestational age of 31.6 weeks. A reduction in the highest CO2 level on day one after birth was observed after the introduction of EtCO2 monitoring (p=0.043). There was also a reduction in the magnitude of difference in CO2 levels on days one (p=0.002) and four (p=0.049) after birth. There was no significant difference in the number of blood gases.
Conclusion: Continuous end-tidal capnography monitoring in ventilated infants was associated with a reduction in the degree of the magnitude of difference in CO2 levels and highest level of CO2 on the first day after birth.
