[Anesthetic management of a patient with Swyer-James syndrome].

Swyer-James syndrome (SJS) shows the constellation of radiographic findings of a small, hyper lucent lung, with an ipsilateral, diminished peripheral vasculature, air trapping, and a lack of peripheral fill on bronchography. We report a case of 70-year-old woman with SJS who underwent pulmonary resection of the normal side lung for lung tumor. Because of this syndrome, we could predict the hypoxia during one-lung ventilation. In fact, about ten minutes after beginning of one-lung ventilation, Sp(O2) decreased from 100% to 90%. As we could not improve the hypoxia in spite of increasing FI(O2), O2 administration to the operating side lung was started. Sp(O2) recovered after O2 administration. For anesthetic management of a patient with SJS in the normal-side-lung, it is essential to prevent the hypoxia during one-lung ventilation.
