A CASE OF TRACHEOMALACIA DURING ISOFLURANE ANESTHESIA

Tracheomalacia is a rare disease. Congenital tracheomalacia manifests itself in infancy and may not resolve as the child grows. Acquired tra cheomalacia has been reported sporadically, resulting from trauma (inc luding tracheostomy), tumor, infection, inhalation of chronic irritant s, and others (1-5). We present a case of tracheomalacia in a female p atient with no respiratory problem. She had difficulty in the expirato ry phase of spontaneous respiration during general anesthesia because of an extreme narrowing of the tracheal lumen on each expiration that was confirmed by bronchoscopic study.
