Abstract: Objective: To evaluate the effects of one lung ventilation on hemodynamics and blood gas during thoracoscopic surgery in piglets. Methods: Eight domestic pigs weighting (7.1±0.7) kg were included in this study. The anaesthesia was maintained with 1% isoflurance. After tracheotomy, an endotracheal tube was positioned in the left mainstem bronchus. Hemodynamic parameters as well as blood gas analyses were obtained using Swan-Ganz and arterial catheter. Results: During one lung ventilation, pulmonary artery pressure increased from (15.8±1.5) mm?Hg to (19.5±2.3) mm?Hg. Arterial oxygen saturation, blood gas analyses and other hemodynamic parameters remained unchanged. Conclusion: One lung ventilation was well tolerated in regard to hemodynamics and blood gas analyses in piglets.
