Clinical use of low-volume anesthesia with inhalation of desflurane in one-lung ventilation

Objective To observe the influences of low-volume anesthesia technology with inhalation of desflurane on circulation and respiratory systems during one-lung ventilation. Method Forty-five patients with pulmonary tumor were undertaken pneumonoresection in low-volume anesthesia technology with inhalation of desflurane, and all ventilated with one-lung during the Surgery. Blood-gas analysis was done at the different time. Results compared with preanesthesia,there is a significant difference in SBp after 8~10minutes inhalation of desflurane(P0.05),while MAP and DSP decrease lightly(P0.05). After 15minutes with one-lung ventilation, blood-gas analysis show us that PaO2 decreases while PaCO2 elevates,and by increasing FiO2 and respiratory frequency they revert to normal. Conclusion low-volume anesthesia technology with inhalation of desfluurane is safe and effective in one-lung ventilation during thoracic Surgeries.
