Recent advancement in ultrasound technology allows us to visualize detailed structures around the airway. One of the important roles of the airway ultrasound is to identify cricothyroid membrane where the emergent invasive access should be performed. ⋯ Airway ultrasound can also be used to confirm correct position of the tracheal tube and laryngeal mask, difficult laryngoscopy prediction in obese patients, assessing vocal cord function, prediction of the post extubation stridor, and so on. We also introduce perioperative evaluation of the airway via sonography (PEAS) protocol in this review.

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.

Case Reports
[Anesthetic management of a patient with Sturge-Weber syndrome associated with a giant facial hemangioma].
A 32-year old man with Sturge-Weber syndrome, a rare congenital disease of multiple angiomatous lesions including cervical cortex, face, oral soft tissues, larynx and trachea, underwent the excision of a back lipoma. His hemangioma which extended into the region of the right ophthalmic nerve and superior maxillary nerve is extremely large. He also had mental retardation and epilepsy. ⋯ He was extubated without bleeding and respiratory problems. We experienced general anesthesia of a patient with Sturge-Weber syndrome who had a giant facial hemangioma. With full-face NIPPV mask we safely induced general anesthesia.

Case Reports
[Anesthetic management of a patient with osteogenesis imperfecta combined with mandibular defect].
Osteogenesis imperfecta (OI) is a rare hereditary disorder characterized by an excessive tendency to bone fractures and retarded growth. We report an anesthetic management of the patient with OI who has the history of vertebral bone fracture by coughing. A 44-year-old female underwent mandibular resection and reconstruction with a metal instrument due to ossifying fibroma 35 years ago. ⋯ Considering incomplete respiration after extubation, the tracheal tube was extubated after inserting the tube exchanger into the trachea through the tube. The tube exchanger was pulled out after confirming spontaneous respiration and upper airway patency. The patient was cooperative, and respiratory and hemodynamic conditions were stable throughout.

Paraplegia is a serious complication after thoracoabdominal aortic aneurysm repair. Therefore, maintenance of spinal cord perfusion pressure, drainage of cerebrospinal fluid, and avoidance of opioids are important for prevention of paraplegia Management of acute post-thoracotomy pain is necessary not only to keep the patient comfortable but also to minimize postoperative complications. However, epidural analgesia, a common method of pain control, is hard to use because of existing postoperative coagulopathy and avoidance of spinal cord ischemia Although both paravertebral block and epidural analgesia provide comparable pain relief after thoracic surgery, paravertebral block has lesser detrimental effects on spinal cord perfusion and better preserves the possibility to monitor neurologic function than epidural analgesia. We report 7 cases in which paravertebral blockade was used for analgesia in patients who underwent thoracoabdominal aneurysm repair.
