Comparative Study
[Comparative study of the KingVision videolaryngoscope and Airwayscope using manikins].
KingVision (KV) is a new videolaryngoscope. In this study, we compared the ease of use of the KV with the Airwayscope (AWS) by experienced personnel in a simulated manikin. ⋯ KV may be a suitable device for routine anesthesia care and difficult airway intubation. Further studies in a clinical setting are necessary to confirm these findings.

General anesthesia was successfully performed in an 86-year-old woman with severe tracheobronchomalacia Tracheobronchomalacia in adult is a very rare disease, characterized by weakness of the trachea and bronchi, causing luminal narrowing during expiration. The patient had laparoscopic cholecystectomy. We used propofol, remifentanil, and rocuronium for induction of anesthesia. ⋯ The patient did well, and was discharged from the hospital 3 days after the operation. In this case, no special care such as postoperative CPAP was necessary, but normally, general anesthesia for a patient with tracheobronchomalacia requires attention. We gave general anesthesia satisfactorily in a patient with tracheobronchomalacia.

Case Reports
[Case of respiratory arrest during intraoperative magnetic resonance imaging (iMRI) for awake craniotomy].
We had a neurosurgical patient who developed apnea during iMRI. She was suspected of obstructive sleep apnea. The tumor had a risk of motor aphasia, and therefore awake craniotomy with iMRI was planned. ⋯ Awake craniotomy could be challenging because of unsecured airway with risks of vomitting, epileptic attacks or unstable level of consciousness. It is considered that the patient monitoring becomes more difficult when iMRI is performed because the patient's face cannot be obsereved directly. We should remember that conscious level as well as respiration pattern may change during operation.

The i-gel is a rescue device for ventilation or tracheal intubation in patients with a difficult airway. The aim of this study was to evaluate the safety and reliability of fiberoptic-guided intubation through the i-gel in anesthetized patients with no history of difficult intubation undergoing elective surgery. ⋯ Fiberoptic-guided intubation could be performed safely through the i-gel. The i-gel is considered to be potentially useful as an alternative conduit for fiberoptic-guided intubation.

We report a case of successful procedural sedation using dexmedetomidine (DEX) in a 68-year-old woman undergoing left gasserian ganglion block for intractable trigeminal neuralgia. DEX was chosen to provide an effective sedation and clear communication about the injection of drugs or thermocoagulation. After 15 minutes of DEX administration at 0.8 microg x kg(-1) x hr(-1), nerve block needle insertion was bearable. ⋯ High-frequency thermocoagulation elicited tolerable radiating pain with minimum vital sign change. She was comfortable and had no communication difficulty under DEX sedation. DEX sedation for interventional pain management during procedures such as gasserian ganglion block may be useful.
