A 54-year-old man (height 155 cm, weight 49 kg) was scheduled for retroperitoneoscopic nephrectomy. He had a history of schizophrenia that had been controlled with propericiazine 10 mg and bromperidol 3 mg daily for 34 years. After induction of anesthesia, 1% mepivacaine 5 ml was administered via an epidural catheter. ⋯ Surgery was cancelled and he was extubated 45 minutes later without any complications. These findings suggest that caution must be exercised when combining general and epidural anesthesia for patients on long-term major tranquilizers. In the event of refractory hypotension, the use of direct-acting vasoconstrictors such as noradrenaline or vasopressin should be considered.

Case Reports
[Use of the air-Q laryngeal airway and tube exchanger in a case of difficult tracheal extubation after maxillectomy].
A 79-year-old man was diagnosed with maxillary cancer and underwent total maxillectomy under general anesthesia. The oropharyngeal airway was needed for efficient mask ventilation during anesthesia induction. The maxilla was totally resected and reconstructed with skin from a femoral flap. ⋯ We confirmed sufficient spontaneous breathing and no active bleeding in the pharynx. After re-inserting the TE thorough air-Q, the air-Q was removed, followed by removal of the TE. These findings suggest that the air-Q and TE were effective in a case of difficult extubation after maxillectomy.

Case Reports
[Anesthetic management of hip joint fracture surgery in an elderly patient with giant pulmonary artery aneurysm].
We report anesthetic management of an elderly patient with giant pulmonary artery aneurysm undergoing hip joint fracture surgery. Preoperative chest computed tomography showed a main pulmonary artery aneurysm with a maximal size of 55 mm. ⋯ Hypoxemia and hypothermia were avoided for the purpose of preventing an increase in pulmonary vascular resistance. Surgery was uneventful because of anesthetic management considering pulmonary hypertension.

Randomized Controlled Trial Comparative Study
[Comparison of the Supreme Laryngeal Mask Airway(SLMA), single use, with the reusable Proseal Laryngeal Mask Airway(PLMA) in anesthetized adult Japanese patients].
Supreme laryngeal mask airway (SLMA) is a single use, new supraglottic airway device with anatomically designed curved airway conduit. It has second channel for gastric tube insertion. We compared the performance of the SLMA with that of the Proseal LMA (PLMA), the older reusable LMA, during anaesthesia in spontaneously breathing adult patients. ⋯ Our result indicated that SLMA can be inserted faster without inserting one's finger into patient oral cavity. Leak pressure was lower but acceptable for clinical use in spontaneously breathing anesthetized adult patients.

Most patients with arteriosclerosis obliterans (ASO) have severe complications such as coronary artery disease, congestive heart failure and chronic kidney disease. They receive long-term antithrombotic therapy which is a contraindication to neuraxial anesthesia. In this retrospective study, we reviewed nine high-risk patients with ASO (revised cardiac risk index more than three) who underwent an urgent lower limb surgery under ultrasound-guided peripheral nerve block (PNB). ⋯ In eight of the nine cases, analgesics are not required until 10 hours after the operation. No complication related to PNB occurred. Ultrasoundguided PNB for patients with ASO undergoing lower limb surgery can be a useful anesthetic technique, providing cardiovascular stability and good postoperative analgesia.
