Abstract/OtherAbstract:
Aim:  To evaluate the accuracy in transcutaneous (Tc) blood gas monitoring in newborn infants, including extremely low birth weight infants, during neonatal intensive care. Methods:  Tc pO2/pCO2 was monitored in the NICU during stable infant conditions. In comparison simultaneous arterial pO2 and pCO2 was measured. Sixty measurements were performed in 46 infants with median(range) birth weight of 0.93(0.53-4.7) kg and at median(range) age of 8.5(1-44) days. Comparison of measurements was performed using Bland-Altman plots and the mean(95%CI) of the difference was calculated. Comparison was also performed in relation to body weight, postnatal age, and oxygen requirement. Results:  The mean(95%CI) difference in pO2 (TcPO2-aPO2) was 0.3(-0.2 to 0.9) kPa, and the corresponding difference in pCO2 (TcPCO2-aPCO2) was 0.4(0.03 to 0.8, p<0.05) kPa. Some differences were related to body weight, age, and oxygen requirement but these differences were small. Conclusion:  There was good agreement between TcPO2/TcPCO2 and corresponding arterial measurements. The mean difference between the methods was small and clinically acceptable in a current NICU. Tc blood gas monitoring could be recommended as a valuable complement for blood gas monitoring also in extremely low birth weight infants.
