Randomized Controlled TrialThe association between the initial end-tidal carbon dioxide difference and the lowest arterial oxygen tension value obtained during one-lung anesthesia with propofol or sevoflurane.
The purpose of this study was to examine the correlation between the lowest PaO(2) value recorded during the first 45 minutes of one-lung ventilation (OLV) and the end-tidal CO(2) (ETCO(2)) difference between two-lung ventilation (TLV) and the early phase of OLV. ⋯ The present study indicates that the ETCO(2) difference between TLV and early OLV has an association with impaired oxygenation later during OLV. This would be a simple and clinically convenient predictor of the lowest PaO(2) value likely to be reached during one-lung anesthesia with either propofol or sevoflurane.

Randomized Controlled TrialEffects of ventilatory mode during one-lung ventilation on intraoperative and postoperative arterial oxygenation in thoracic surgery.
The purpose of this study was to investigate the relationship between the ventilatory mode used during one-lung ventilation (OLV) and intraoperative and early postoperative arterial oxygenation in patients undergoing thoracic surgery. ⋯ In patients undergoing thoracic surgery, the use of PCV compared with VCV during OLV with the same Vt of 8 mL/kg does not affect arterial oxygenation during OLV or early postoperative oxygenation.
