Implication

Comparative study reveals superior accuracy of transcutaneous carbon dioxide monitoring in thoracic surgery patients, suggesting greater reliability during one-lung ventilation.

Key Points

To evaluate the accuracy of transcutaneous carbon dioxide monitoring compared to end-tidal carbon dioxide monitoring relative to arterial carbon dioxide levels during thoracic anesthesia.
Studied 26 patients undergoing pneumonectomy with thoracotomy requiring prolonged one-lung ventilation (OLV) in the lateral decubitus position.
Simultaneously recorded transcutaneous carbon dioxide (PTCCO2), end-tidal carbon dioxide (PETCO2), and arterial carbon dioxide (PaCO2) at 15-minute intervals during both two-lung ventilation (TLV) and OLV.
Assessed method agreement and accuracy using Bland-Altman bias and precision analyses against arterial measurements.
Comparison between PTCCO2 and PaCO2 showed a bias of -0.4 mm Hg (precision ±2.5 mm Hg) during OLV and 1.4 mm Hg (precision ±4.3 mm Hg) during TLV.
Comparison between PETCO2 and PaCO2 demonstrated a bias of -5.8 mm Hg (precision ±4.1 mm Hg) during OLV and -7.1 mm Hg (precision ±4.6 mm Hg) during TLV.
