Effects of thoracic epidural anaesthesia on pulmonary venous admixture and oxygenation during one-lung ventilation

Abstract

Background: In this clinical randomized study, the effects of four anaesthesia techniques during one-lung ventilation [total intravenous anesthesia MVA) with or without thoracic epidural anaesthesia (TEA) (G-TWA-TEA and G-TWA), isoflurane anaesthesia with or without TEA (G-ISO-TEA and G-ISO)] on pulmonary venous admixture (Qs/Qt) and oxygenation (OW were investigated.
