We successfully performed intraoperative dexmedetomidine (DEX) administration for the prevention of emergence agitation or postoperative delirium after lung resection in four patients (71.3 ± 5.7 year old, 3 males and 1 female) with a past history of postoperative delirium. DEX was started at 0.35-0.45 μg x kg(-1) x hr(-1) continuously without loading. ⋯ No patient had emergence agitation, and DEX administration was continued until the following morning with monitoring in all patients without any symptoms of delirium. Intraoperative DEX administration may be beneficial for the prevention of emergence agitation or postoperative delirium in patients with a past history of postoperative delirium.

A 51-year-old man, 170 cm, 86 kg, was diagnosed with a tracheal tumor existing just below the glottis occupying more than 80% of his tracheal lumen, and was scheduled for tracheal resection and construction. The patient had a strider due to the severe tracheal stenosis. We could insert i-gel easily under dexmedetomidine sedation. ⋯ Followed by ETT insertion, tracheal resection and construction were performed under general anesthesia. After the operation, the patient was extubated and transferred to the intensive care unit (ICU), where he was given DEX infusion to keep the tracheal anastomosis immobilized. There was no serious complication during the perioparative period.

An obese patient was scheduled for shoulder joint surgery under general anesthesia. After induction of anesthesia and tracheal intubation, insertion of a gastric tube was difficult. A new tracheal tube was prepared, the connecter was removed, and the tube was cut longitudinally. ⋯ The tracheal tube was carefully taken out from the esophagus leaving the gastric tube in the stomach. The cut tracheal tube was peeled off from the gastric tube. Correct positioning of the gastric tube was re-confirmed.

We report the case of a 52-year-old woman with May-Hegglin Anomaly (MHA) and a platelet count of 1.9 x 10(4) x mm(-3). She was scheduled to undergo abdominal total hysterectomy and adnexectomy with uterine fibroids. Anesthesia was maintained by inhalation of sevoflurane (1.5%), continuous intravenous infusion of remifentanil (0.2-0.3 μg x kg(-1) x min(-1)), intermittent intravenous infusion of fentanyl (35 μg), and the transversus abdominis plane block with 20 ml of 0.375% ropivacaine. ⋯ MHA is a rare hematological disorder inherited as an autosomal dominant trait that is characterized by thrombocytopenia, giant platelets, and inclusion bodies in the granulocytes. A decrease in platelet count is detectable with a blood test But function of platelets is generally normal. Anesthesiologist should understand the characteristics of MHA, and administer anesthetics without giving platelets.

Airway management in a patient with Forestier's disease can be challenging clinically because this disease may cause not only dysphagia but also airway obstruction due to the compression of the pharynx and esophagus caused by the ossification of anterior longitudinal ligament. We report our anesthetic management in a patient with Forestier's disease. Meanwhile, we studied the causes of difficult airway and the most suitable airway device for a patient with this disease from a standpoint of anatomy of upper airway. Our study indicated the possibility that the most suitable airway device differed depending on the actual location of the ossification of anterior longitudinal ligament in the cervical spine and that more prudent airway management would be required if its lesion location extended to upper cervical spine.
