Abstract

To be able to judge the significance of changes in transcutaneous blood gas values between repeated measurements in patients it is necessary to know possible variations in these values in healthy children/adolescents.
The aim of the study was to establish transcutaneous oxygen tension (tcPO₂), carbon dioxide tension (tcPCO₂) and oxygen saturation (tcSO₂) values and to investigate the intra- and inter-individual variation in these values in healthy children/adolescents.
Forty-one children/adolescents (mean age 12.1 years, SD 3.5) participated. Continuous recordings of tcPO₂, tcPCO₂ and tcSO₂ were made for 30 minutes at two occasions with 10.3 days in between. The mean values of tcPO₂, tcPCO₂ and tcSO₂ during the last five minutes of the recordings were reported.
At the first recording the mean was for tcPO₂ 10.8 kPa (SD 1.0), tcPCO₂ 5.1 kPa (SD 0.4) and tcSO₂ 97.4 % (1.1). The mean intra-individual variation was in tcPO₂ 0.3 kPa (SD 1.0), tcPCO₂ 0.0 kPa (0.5) and tcSO₂ 0.1 % (1.3). No significant differences were observed in these values between the recordings.
The reproducibility of tcPO₂, tcPCO₂ and tcSO₂ monitoring in healthy children/adolescents were good. This indicates that transcutaneous monitoring may be used to document significant changes in blood gases over periods of time.
