Effect of tidal volume on extravascular lung water content during one-lung ventilation for video-assisted thoracoscopic surgery: a randomised, controlled trial.

BACKGROUNDThe use of low tidal volume during one-lung ventilation (OLV) has been shown to attenuate the incidence of acute lung injury after thoracic surgery.OBJECTIVETo test the effect of tidal volume during OLV for video-assisted thoracoscopic surgery on the extravascular lung water content index
