Abstract
OBJECTIVE:: To assess the agreement of transcutaneous carbon dioxide (TcPCO2) and end tidal carbon dioxide (PetCO2) with arterial carbon dioxide (PaCO2) values in infants < 28 weeks gestational age. STUDY DESIGN:: In all, 27 ventilated preterm infants were prospectively studied. PaCO2 was compared with TcPCO2 and PetCO2 measured at three similar time points within first 24 hours after birth. RESULTS:: The Intraclass correlation coefficients for TcPCO2 and PaCO2 were 0.45, 0.73 and 0.53; and for PetCO2 and PaCO2 were 0.61, 0.56 and 0.57 at 4, 12 and 24 hours after birth, respectively. CONCLUSION:: A moderate agreement with a wide variation in individual values was observed between noninvasive methods and PaCO2 in preterm infants in the first 24 hours. Noninvasive monitoring methods cannot be substituted for PaCO2 analyses in preterm infants during this critical period.
