A 9-year-old boy was scheduled for excision of tracheal granuloma which had developed at the tip of a tracheostomy tube. Instead of a tracheostomy tube, a 4 mm ID tracheal tube was inserted via the tracheostomy beyond the tracheal constriction because of rapid development of respiratory failure. General anesthesia was induced and maintained with sevoflurane and oxygen via the tube, and a size 2.5 laryngeal mask airway (LMA) was inserted without muscle relaxant. ⋯ After sealing the tracheostomy, he could breath spontaneously through the LMA. During the excision of tracheal granuloma by holmium:YAG laser, fiberoptic observation was continued via the LMA, and the procedure was performed without any complication. We conclude that the tracheal stenosis can be managed using the LMA, continuous fiberoptic monitoring and additional option of keeping spontaneous ventilation.

Case Reports
[Anesthetic management for cesarean section in a patient with corrected transposition of great arteries].
A 20-year-old woman with corrected transposition of great arteries (height 163 cm, weight 69 kg) was scheduled for elective cesarean section at 36 weeks of gestation. Since her mitral insufficiency had deteriorated during pregnancy, she developed dyspnea and lower cardiac function. We decided to perform general anesthesia for her cesarean section. ⋯ No cardiac events were observed during surgery. The postoperative course was uneventful, and the patient was discharged from the hospital on the 10th postoperative day. Swan-Ganz catheter was useful for the evaluation of cardiac function and for anesthetic management.

We experienced anesthetic management of two cases of amyotrophic lateral sclerosis (ALS). Case 1. A 46-year-old woman underwent emergency operation for ileus. ⋯ During and after the operation, she was in good general condition and had no pain. For the patients with ALS, prolongation of muscle relaxation and residual neuromuscular block effect may cause difficult tracheal extubation and postoperative respiratory complications. We observed carefully the condition of the patients with ALS, and were able to choose the minimum invasive anesthetic methods for each case.

We experienced an anesthetic management for a patient of myotonic dystrophy with pheochromocytoma. Much attention is required to manage myotonic dystrophy on surgical manipulation. This disease interacts with anesthetic drugs. ⋯ Though, this patient was not fully awake from anesthesia and could not take enough breaths on his own. We extended the period of spontaneous breathing with careful check whether the patient has resumed spontaneous breathing. It took us fourteen days till extubation.

We recently had opportunities to use an improved bronchial blocker (Phycon TCB bronchial blocker) in surgical patients who needed separation of the lungs and/or one-lung ventilation. This blocker provides a high torque control and can be easily manipulated into the desired site of the lungs. Our clinical experience shows that this blocker is useful particularly when the quick and sure separation of the lungs is crucial or when the insertion of a double-lumen tube is very difficult.
