A 22-year-old muscular karate player was diagnosed to have a tracheal tumor with a diameter of 2.8 cm that existed 2 cm under the glottis and occupied 60% of his trachea. He was scheduled for trachea resection and construction surgery. After awake-fiber intubation, anesthesia was maintained by continuous infusion of propofol and remifentanil, together with thoracic epidural anesthesia (T4-5). ⋯ It took almost 10 minutes to stop shivering completely, and the patient became too sedated and required noninvasive positive pressure ventilation overnight. We speculate that intraoperative remifentanil infusion induced severe shivering in this case. Shivering after remifentanil infusion can be a fatal complication in tracheal resection and construction surgery, especially in muscular patients.

The case of a patient who might have developed nasogastric tube syndrome at the end of anesthesia is presented. A 62-year-old woman was scheduled for a general anesthesia with fiberscopic oro-tracheal intubation because of a predicted difficult airway. After the smooth and gentle intubation without any trauma and injury, a nasogastric tube was inserted blindly. ⋯ Extubation was cancelled and the patient was moved to an intensive care unit for respiratory management. On the next day, fiberscopic observation revealed a complete recovery and the endotracheal tube was removed without any difficulty. We strongly suspected the pharyngeal injury as acute nasogastric tube syndrome and an attention to this rare complication is required by anesthesiologists.

Fiberoptic intubation is the most reliable method in patients with difficult airways, but it may be difficult in patients with restricted neck movement. The intubating laryngeal mask airway facilitates fiberoptic intubation, but its insertion may also be difficult in some circumstances. We experienced a case of successful tracheal intubation using the Pentax-AWS (Airway Scope) after failed fiberoptic intubation and failed insertion of the intubating laryngeal mask. ⋯ Insertion of the laryngeal mask also failed, because the pharyngeal swelling prevented its insertion. Insertion of the Pentax-AWS was unaffected by the swelling and tracheal intubation was successful within 10 sec. We believe that the Pentax-AWS can be useful in the patient with restricted neck movement in whom both fiberoptic intubation and insertion of the laryngeal mask have failed.

Vocal cord synechia causes respiratory disturbance and severe pneumonia. A 63-year-old woman with recurrent laryngeal nerve paralysis caused by translaryngeal intubation after resection of acoustic tumor and by thyroid surgery in her history and progressive dyspnea, had received vocal cord synechiotomy under general anesthesia. Preoperative endoscopic examination revealed edematous larynx, immobility of left unilateral vocal fold, insufficient mobility of right vocal fold, left arytenoid cartilage dislocation and a posterior glottic adhesion. ⋯ Trachea was cannulated immediately after incision of the scar under indirect video laryngoscopy. Vocal cord synechiotomy was completed without any respiratory complication. The case indicated that recurrent laryngeal nerve paralysis has a potential for vocal cord synechia and difficulty of tracheal intubation, and visibility of the surgical field among anesthesiologists and surgeons by indirect video laryngoscopy for vocal cord synechiotomy contributes to establish prompt surgical manipulation and tracheal intubation as to vocal cord synechiotomy.

Case Reports
[Hemodynamic changes during pregnancy and cesarean delivery in three cases of triplet pregnancy].
Polypregnancy is one of the major problems to both mothers and fetuses leading to poor prognosis. Even though hemodynamic parameters change greatly during pregnancy and cesarean delivery, it is unclear how blood volume (BV) and cardiac output (CO) increase during triplet pregnancy and how CO goes up and down during cesarean delivery in the cases of triplet pregnancy. ⋯ However, there was no such tendency in CO. When they underwent cesarean delivery under combined spinal-epidural anesthesia (CSEA) or sequential-CSE (S-CSE) receiving a 10 or 12 mg intrathecal isobaric bupivacaine with 20 microg fentanyl, CO decreased in parallel with blood pressure from ten minutes after spinal anesthesia, to the start of operation and just after the birth of third fetus.
