Abstract Objective To evaluate the effect of one lung ventilation (OLV)on patient’s cardiac function and hemodynamic status during thoracic surgery by FloTrac/Vigileo system.Methods A total of 101 class Ⅰ-Ⅱ adult patients by American Society of Anesthesiologists (ASA) who had undergone the double lumen endotracheal intubation in the lateral position during thoracic surgery were enrolled in this study. Each hemodynamic parameter was recorded by FloTrac /Vigileo system at different time points that included the time before anesthesia induction(T₀), 5 min into intubation in the supine position by two lung ventilation (T₁) , 5 min after the lateral position by two lung ventilation(T₂),5 min after OLV (T₃) ,10 min after OLV(T₄) , 30 min after OLV(T₅), 60 min after OLV(T₆) ,after lung inflation (T₇),and 5 min after the supine position by two lung ventilation (T₈).Results MAP and HR were higher at T₀ than at T2 (P<0.05).SVR was higher at T₁ than at T₆ (P<0.05).MAP, HR, CO and CI were lower at T₁、T₃ than at T₄ (P<0.05). MAP was higher at T₂ than at T₄, and HR was lower at T₃ than at T₄ (P<0.05). SpO₂ was the lowest at T₅ (P<0.05). HR was higher at T₆ than at T₇, while MAP and SV were lower at T₆ than at T₇ (P<0.05).Conclusions After one lung ventilation, patients can experience transient hemodynamic instability, for MAP, HR, CO and CI tend to increase while SpO₂ and SVR tend to decrease compared with double lung ventilation. However, as the one lung ventilation continues, the indicators gradually become stable.
