Abstract
Although recent investigations have shown the clinical usefulness of the transcutaneous oxygen tension (tcPO2) in newborn infants, there are very limited data available in the age group from 1-21 years. In order to assess the usefulness of tcPO2 in the pediatric age group, tcPO2 was continuously monitored and compared with simultaneous arterial oxygen tension (PaO2) in 67 patients with cardiorespiratory problems. Patients were subdivided into two groups: (1) patients during cardiac catheterization (56) in whom the PaO2 ranged between 34-98 mmHg (mean 72.4±17 mmHg) and (2) patients in the Intensive Care Unit (11) in whom the PaO2 ranged between 71-158 mmHg (mean 119±31 mmHg). Ages ranged from 1.5 to 23 years (mean 7.7 years). Blood samples were drawn via an indwelling arterial catheter during periods in which the tcPO2 recording showed stable values over 3 minutes. Studies lasted for 30-210 min. (mean 80±33.4 min). A total of 118 arterial blood samples were obtained simultaneous to the tcPO2 recordings. The overall relationship between tcPO2 and PaO2 in the 67 patients studied was r=0.96 (P < 0.001), tcPO2 slope 0.89, SEE = 6.8 and the intercept 3.0 mmHg. There was no difference in the correlation coefficient (r) between the two groups of patients. We conclude, therefore, that tcPO2 measurement is a reliable method for assessing the arterial oxygen tension.
