Summary
Brief summary
This study compared inflammatory and oxidative stress, and respiratory outcomes between conventional and protective OLV in patients with normal lung function undergoing video-assisted thoracoscopic (VATS) lobectomy due to lung cancer.
Fifty ASA 1-2 patients undergoing elective VATS lobectomy were randomly assigned into conventional (CV: tidal volume 10 ml/kg, FiO2 1.0, zero positive end-expiratory pressure under volume-controlled ventilation) or protective (PV: tidal volume 6 ml/kg, FiO2 0.5, positive end-expiratory pressure 5 cmH2O under pressure-controlled ventilation) OLV group. Respiratory parameters, arterial blood gases, blood malondialdehyde (MDA) and interleukin 6 (IL 6) were analyzed at baseline, 15 min and 60 min after OLV (OLV 15 and OLV 60, respectively), and 15 min after the restoration of two lung ventilation (TLV 15). Postoperative chest radiography (CXR) and respiratory outcomes were also evaluated.
