Noninvasive monitoring of carbon dioxide in infants and children with congenital heart disease: end-tidal versus transcutaneous techniques.

摘要

End-tidal CO(2) (ET(CO)(2)) monitoring and transcutaneous (TC) CO(2) monitoring were prospectively compared in 53 patients, 1 month to 16 years of age, with congenital heart disease (CHD). There were 32 patients with cyanotic CHD and 21 with acyanotic CHD. The TC-PaCO(2) difference was 2 +/- 1 mm Hg and the ET-PaCO(2) difference was 5 +/- 3 mm Hg (P < .0001). The TC-PaCO(2) difference was/=1 year of age (6 +/- 3 mm Hg vs 4 +/- 2,P = .008). In infants and children with CHD, TC monitoring provides a more accurate estimation of PaCO(2) than ET monitoring.
