Background: Several reports have demonstrated substantial mean differences between arterial carbon dioxide
tension (PaCO2) and end-tidal carbon dioxide tension (ETCO2) in children under anesthesia.
Aim: We explored the importance of the (a-ET) PCO2 gradient in a pediatric population receiving general
anesthesia, with special attention to the relative effects of age and weight.
Methods: After induction of general anesthesia, 129 children, ASA I or II, and between 1 day and 15 years old,
had an endotracheal tube placed and mechanical ventilation initiated. After reaching a steady-state ETCO2, an
arterial blood sample was obtained and the PaCO2 measured.
Results: The mean (a-ET) PCO2 was 1.6 ± 4.3 mmHg for the entire pediatric population. There was a significant
negative correlation between (a-ET) PCO2 and age and weight (r =.. View More»
