Anesthetic management of a patient with giant mediastinal tumors is challenging from the perspective of both cardiovascular and respiratory management. We report the successful use of the Pentax-AWS Airwayscope (AWS; Hoya, Japan) and a tracheal tube introducer in the left lateral position for a patient with a giant mediastinal tumor. An 18-year-old man weighing 62 kg was scheduled for resection of a giant mediastinal tumor. ⋯ The head of the double-lumen tube was placed in the right bronchus under the guidance of a bronchofiberscope. Following tracheal tube placement, posture was shifted from the left lateral position to supine position without affecting vital signs. After median sternotomy, a muscle relaxant was administered for immobilization.

We report a case of successful tracheal intubation of a double-lumen tube with combined use of a videolaryngoscope (GlideScope) and a fiberoptic bronchoscope, in a patient with difficult airway, in whom intubation using the GlideScope had failed. A 71-year-old man with lung cancer was scheduled for the middle lobe lobectomy under general anesthesia. ⋯ While the GlideScope was in place to obtain a view near the glottis, a fiberoptic bronchoscope (passed through the double-lumen tube) was insertd into the trachea, and the tube was passed over the scope into the trachea. We believe that, when tracheal intubation of a double-lumen tube using a videolaryngoscope or fiberoptic bronchoscope is difficult, their combined use may be useful in a patient with difficult airway.

We report the successful rescue ventilation of a patient with severe obstructive sleep apnea syndrome after induction of general anesthesia using the i-gel supraglottic airway device. A 55-year-old man was scheduled for resection of a cerebellopontine angle tumor. He suffered from severe obstructive sleep apnea syndrome and routinely used continuous positive airway pressure. ⋯ We immediately inserted the i-gel device to provide sufficient ventilation. As tracheal intubation with the i-gel device was difficult, we intubated a spiral tube (internal diameter, 8.0 mm) using the Pentax-AWS Airwayscope. Our findings suggest that the i-gel device may be useful for emergent airway rescue in the event of impossible ventilation for patients with severe obstructive sleep apnea syndrome.

Pentazocine has activities both of kappa-opioid receptor agonist and weak micro-opioid receptor antagonist. Recent study has suggested that kappa-opioid receptor agonists have antipruritic effects. We experienced a case of pentazocine inhibiting itch evoked by intrathecal fentanyl in a patient with idiopathic pulmonary fibrosis (IPF). ⋯ Following that, when pentazocine was administered intravenously, pruritus disappeared immediately and then never recurred. Therefore, it is suggested that pentazocine can be useful in reducing pruritus on intrathecal opioid-induced itch. Future studies are necessary to evaluate the efficacy of pentazocine for the treatment and prevention of opioid-induced itch.

Patients with Klippel-Feil syndrome (KFS) frequently encounter difficult airway management due to skeletal abnormalities, including fusion of two or more vertebrae and short neck. We report successful tracheal intubation using the air-Q supraglottic airway device (air-Q). A 46-year-old woman (height, 149 cm; weight, 62 kg) with KFS was scheduled to undergo vertebral arch plasty for cervical spondylotic myelopathy. ⋯ Using a size 2.5 air-Q, sufficient ventilation was finally achieved. We performed fiberoptic tracheal intubation through the air-Q using a tube with an internal diameter of 6.0-mm. We then exchanged the 6.0-mm tracheal tube with a 7.0-mm spiral tube using a 10 Fr tracheal tube introducer.
