【Abstract】 Objective To evaluate feasibility of high frequency jet ventilation (HFJV) during trachea and carinal reconstruction. Methods Ten patients with lung cancer ,scheduled for elective trachea and carinal reconstruction ,were intubated with double lumen tube following routine anesthesia induction. A HFJV tube (ID=3mm) was inserted 3cm into main bronchus. HFJV was applied ,with the respiratory rate of 120/min,I:E=1:2 and drive pressure of 0.15-1.20MPa, after cut off the main bronchus of the opposite side. Blood gas analysis was made before the operation, 15min following one-lung ventilation, 5, 10, 20 min following HFJV and 15min following one-lung ventilation,respectively.Results PaO 2 was significantly higher following HFJV than that one-lung ventilation (P<0.05), very significantly higher than the value of pre-operation(P<0.01).PaCO 2 was kept in normal range during whole procedures. SaO 2 were significantly increased following one-lung ventilation or HFJV as compared with the pre-operative value (P<0.05).Conclusions HFJV can improve the ventilation of patients during the operation of trachea and carinal reconstruction and minimize the interference to the operation.更多还原
