ABSTRACT

Objective To study the effects of High frequency two -way jet ventilation on the function respiratory and circulation of patients with Trachea and Carinal reconstruction.Methods Fifty patients with lung cancer,who were scheduled for elective trachea and carinal reconstruction,were intubated with double lumen tube following anesthesia induction and general anesthesia.High frequency ventilation was used on the healthful main bronchus during carinal reconstruction,a Hunsaker tube was inserted 3cm into the healthful main bronchus.HFTJV was applied with the respiratory rate of 120 /min,the ratio of inspiration and expiration E =11 and drive pressure of 0.2 -0.25Mpa.Blood gas analysis was made before the anesthesia,15 min following one -lung ventilation,10,20, 30 min following HFTJV and 15min following one -lung ventilation,respectively and monitor MAP,HR,SpO2 , PetCO2 .Results PaO2 in high frequency ventilation increased significantly compared with preoperative (78.0 ± 10.5)mmHg,was respectively (161.4 ±10.2)mmHg,(156.0 ±15.7)mmHg,(153.0 ±15.1)mmHg (P 0.05). Conclusion HFTJV is safe and reliable for Trachea and carinal reconstruction.
