Objective

To estimate the accuracy of the transcutaneous carbon dioxide tension measurement (PtCO₂) compared to the measurement of the arterial carbon dioxide tension (PaCO₂).

Material and methods

An analytical, longitudinal, prospective and observational study, of a dynamic cohort taken from the in-patients of a Paediatric Intensive Care Unit (PICU). The PtCO₂ was measured with the SenTec AG analyzer, and the sensor was applied with the specific Multi-Site Attachment Ring. PtCO₂ and PaCO₂ were recorded at the same time. The statistical significance of the association between paired measurements was evaluated with the Snedecor's F test, the Pearson's r² correlation coefficient and the Interclass Correlation Coefficient (ICC). The degree of agreement was evaluated with the Bland & Altman method. The consistency of the results was evaluated with the ANalysis Of the VAriance (ANOVA).

Results

One hundred and six paired measurements, PtCO₂ and PaCO₂, from twelve patients, were compared. The means of the PaCO₂ and PtCO₂ were 51.0 卤13 mmHg and 50.1 卤 14 mmHg, respectively; r² = 0.87 (p < 0.001), ICC = 0.96, (95%CI: 0.94 鈥?#xA0;0.97). The Bland-Altman analysis showed a mean difference of 鈭?#xA0;0.9 mmHg (95%CI: 鈭?#xA0;2.0 to 0.2 mmHg). The correlation was better in cases with no respiratory disease, with low respiratory assistance, with PaCO₂ > 50 mmHg and with the sensor applied on the forehead. The results were consistent. No side effects derived from the use of the ring were observed.

Conclusion

The correlation between PtCO₂ and PaCO₂ is excellent and stable. The ring sensor was safe and easy to use.
