Randomized Controlled Trial
Application of end-tidal carbon dioxide monitoring via distal gas samples in ventilated neonates.
Previous research has suggested correlations between the end-tidal partial pressure of carbon dioxide (PETCO2) and the partial pressure of arterial carbon dioxide (PaCO2) in mechanically ventilated patients, but both the relationship between PETCO2 and PaCO2 and whether PETCO2 accurately reflects PaCO2 in neonates and infants are still controversial. This study evaluated remote sampling of PETCO2 via an epidural catheter within an endotracheal tube to determine the procedure's clinical safety and efficacy in the perioperative management of neonates. ⋯ PETCO2 detected via modified carbon dioxide monitoring had a better accuracy and correlation with PaCO2 in neonates.
