Background and Objectives : Sphincteric function of the larynx, essential to lower airway protection, is most efficiently achieved through strong reflex adduction by both vocal cords. We hypothesize that central facilitation is an essential component of a bilateral adductor reflex and that its disturbance could result in weakened sphincteric closure. Materials and Method : Seven adult 20kg dogs underwent evoked response laryngeal electromyoraphy under 0.5 to 1.0 MAC isoflurane anesthesia. The internal branch of superior laryngeal nerve was stimulated through bipolar platinum-iridium electrodes and recording electrodes were positioned in the ipsilateral and contralateral thyroaryteonoid muscles. Results : Consistent threshold responses were obtained ipsilaterally under all anesthetic levels. However, contralateral reflex responses disappeared as anesthetic levels approached 1.0 MAC. Additionally, at 0.5 MAC, late responses (R2) were detected in one animal. Conclusion : Alteration of central facilitation by deepening anesthesia abolishes the crossed adductor reflex, predisposing to a weakened glottic closure response. Precise understanding of this effect may improve the prevention of aspiration in patients emerging from prolonged sedation or under heavy psychotropic control.

A 25 years old male patient was experienced Trough method operation to correct of Tracheal stenosis following Tracheostomy. After admission, a No.3 Magill plastic portex tube had been placed in the previous tracheostomy opening. Stenotic narrowing portion was noted low trachea (about 3.5cm above carina) Despite of narrowing of the lesion, anesthetic course was uneventful with oxygen, halothane and non depolarized muscle relaxant by controlled respiration. Postoperative coures were also favorable With adequate respiratory cares and blood gas analyzed.

The inferior alveolar nerve (IAN) block is the most frequently used mandibular injection technique for achieving local anesthesia for restorative and surgical procedures. However, The IAN block does not always result in successful anesthesia, especially pulpal anesthesia. Lidocaine is used as a "standard" local anesthetic for the inferior alveolar nerve. Articaine recently joined Korean market as a form of dental cartridge. It has an advantage of superior diffusion through bony tissue. A variety of trial was performed to improve the success rate of inferior alveolar nerve block. In this review, the recent update related with inferior alveolar nerve block anesthesia will be discussed on the anatomical consideration, anesthetic agent, technique, and complications.

The main objective of this study was to provide anesthetic criteria of clove oil for an effective manipulation and transportation of red spotted grouper, Epinephelus akaara. When anesthesia temperature (20, 24, and $28^{\circ}C$) and concentration of clove oil (25, 50, and 75 ppm) were increased, the anesthesia and recovery time decreased and tended to be similar to each other between juvenile and adult. Also, as the temperature and concentration increased, the ratio of exposure time and recovery time between juvenile and adult were decreased. When plasma cortisol concentrations were compared for 48 h after anesthesia with 50 ppm of clove oil, both the juvenile and adult fish grew up to 12 h; however, thereafter decreased and there was no significant difference from control at 48 h.

Inferior alveolar nerve block obtained maximum anesthetic effect using a small dose of local anesthetic agent, which also has low a complication incidence. Complications of an inferior alveolar nerve block include direct nerve damage, bleeding, trismus, temporary facial nerve palsy, and etc. Among them, the major iatrogenic complication is dental needle fracture. A fragment that disappears into the soft tissue would be hard to remove, giving rise to a legal problem. A 31-year-old woman was referred for the removal of a broken needle, following an inferior alveolar nerve block. Management involved the removal of the needle under local anesthesia with pre- and peri-operative computed tomography scans.

Local anesthesia is routine procedure in dental practices and has several complication. One of them, needle fracture is not uncommon in past, but rare in recent. The number of cases reported in the literature of broken needle in local anesthetic procedure has shown a marked decrease since the use of disposable spiral-constructed dental needle began. This complication results from lack of patient cooperation, inaccurate anesthetic technique, sudden movement of patient, error in the manufacturing procedure, use of short needle, and bending before use. Most common site is pterygomandibular space during inf. alveolar nerve block. In two patients, we removed broken needles under general anesthesia without complication. So we report cases with review of literatures.

Pain control by means of local anesthesia is an intrinsic part of clinical practice in dentistry. Several studies evaluated intraligamental anesthesia using a computer-controlled anesthetic device in children. There is a need to provide a clinical guide for the use of computerized intraligamental anesthesia in children. Intraligamental anesthesia using a computer-controlled anesthetic device was found to cause significantly lower pain perception scores and lower pain-related behavior than traditional techniques. This device proven to be effective in restorative and pulp treatment in children; however, its effectiveness in primary teeth extraction is controversial. It is important to withdraw recommendations necessity of future studies concerning the side effects of computerized intraligamental anesthesia in children. The present study aims to review different clinical aspects of computerized intraligamental anesthesia in children along with the side-effects, type of local anesthesia and postoperative pain of this technique. This study provides dentists with a clinical guide for the use of computerized intraligamental anesthesia.

We present here the case of a 13-year-old male patient with Alexander's disease who underwent surgical correction of a femur fracture. Alexander's disease is a rare and fatal disorder that affects the white matter in the brain and it causes developmental delay, psychomotor regression, spasticity, megaloencephaly and seizure. The patient had the possibility of a seizure attack during the perioperative period. We discuss the anesthetic management of a patient with Alexander's disease and we review the relevant literature.
