Effects of Ventilatory Mode During One-Lung Ventilation on Intraoperative and Postoperative Arterial Oxygenation in Thoracic Surgery

One-Lung Ventilation in Anesthesia

“…However, other groups have failed to reproduce the oxygenation benefi t of PCV during OLV [ 37 , 38 ]. A recent study by Pardos et al comparing PCV and VCV with a tidal volume of 8 mL/kg during OLV failed to demonstrate a signifi cant difference in arterial oxygenation between the two ventilatory modes [ 39 ]. This study confi rms previous work on the comparison of volume-control versus pressure-control ventilation for OLV.…”

“…For a right-sided DLT, there is no study available that addresses the issue of optimal size for a determined patient. In general, a 37 French DLT can be used in most of the adult females, while 39 French can be used in the average adult male. Keeping in mind that undersized or oversized DLTs could lead to serious airway complications, including tracheobronchial rupture.…”

“…42 Whether PCV actually improves oxygenation is highly controversial, as studies have failed to find a consistent benefit. 43,44 Recommendation…”

“…Compared with controls under propofol anesthesia, inhaled anesthetics result in attenuation of cytokine elevations in both the ventilated and the operative lung. 44,45 This approach appears to translate into better outcomes, as patients in the sevoflurane arm experienced less composite adverse events. 45 Recommendation…”

“…42 La controverse existe quant à savoir si la VPC améliore véritablement l'oxygénation; en effet, les études n'ont pas démontré de bienfait constant. 43,44 Recommandation…”
