Complex regional pain syndrome (CRPS) is rare, characterized by pain from diverse causes, and presents as extreme pain even with minor irritation. General anesthesia may be required for dental treatment because the pain may not be controlled with local anesthesia. However, treatment under general anesthesia is also challenging. A 38-year-old woman with CRPS arrived for outpatient dental treatment under general anesthesia. At the fourth general anesthesia induction, she experienced severe pain resulting from her right toe touching the dental chair. Anesthesia was induced to calm her and continue the treatment. After 55 minutes of general anesthesia, the patient still complained of extreme toe pain. Subsequently, two administrations for intravenous sedation were performed, and discharge was possible in the recovery room approximately 5 h after the pain onset. The pain was not located at the dental treatment site. Although the major factor causing pain relief was unknown, ketamine may have played a role.

Background: In South Korea, the number of cases of dental treatment for the disabled is gradually increasing, primarily at regional dental clinics for the disabled. This study investigated pediatric patients at a treatment clinic for the disabled within a university hospital who received dental treatment under general anesthesia. This data could assist those that provide dental treatment for the disabled and guide future treatment directions and new policies. Methods: This study was a retrospective analysis of 263 cases in which patients received dental treatment under general anesthesia from January 2011 to May 2016. The variables examined were gender, age, reason for anesthesia, type of disability, time under anesthesia, duration of treatment, type of procedure, treatment details, and annual trends in the use of general anesthesia. Results: Among pediatric patients with disabilities who received dental treatment under general anesthesia, the most prevalent age group was 5-8 years old (124 patients, 47.1%), and the primary reason for administering anesthesia was dental anxiety or phobia. The mean time under anesthesia was $132.7{\pm}77.6min$, and the mean duration of treatment was $101.9{\pm}71.2min$. The most common type of treatment was restoration, accounting for 158 of the 380 treatments performed. Conclusions: Due to increasing demand, the number of cases of dental treatment performed under general anesthesia is expected to continue increasing, and it can be a useful method of treatment in patients with dental anxiety or phobia.

Background: Patients with special health care needs are more likely to develop health problems, including dental problems. Dental treatments require a good level of communication with the patient. Therefore, in these patients, sedation and general anesthesia are an extremely humanistic approach for comfortable and successful treatment. In patients with special needs, there is no standard anesthetic approach due to varying clinical conditions. The aim of this study was to provide literature content about the anesthetic approaches used by us in patients with special needs. Methods: The medical records of 710 patients with special health care needs treated under general anesthesia or sedation were reviewed retrospectively. Demographic data, the American Society of Anesthesiologists classification, Mallampati score, anesthesia duration, anesthesia type, anesthetic and analgesic agents used, dental treatment performed, secondary diseases, and complications in the perioperative period were recorded. Patients were evaluated under five groups: Down syndrome, other syndromes, psychiatric disorders, physical disabilities, and complicated medical story. Results: Among the patients evaluated, 47.5% were females and 52.5% were males (mean age $15.76{\pm}11.17$ years), and general anesthesia and sedation were administered in 72.9% and 22.1% patients, respectively. The mean duration of anesthesia was $43.20{\pm}35.85$ min. Simple dental treatments were performed in all groups, and the most common complications were observed in the other syndromes group. Conclusion: Complications can be reduced by utilizing the appropriate anesthetic approach and taking serious precautions in patients with special needs.

We experienced a case of induction of general anesthesia without using neuromuscular blocking agents (NMBAs) in a 40-year-old woman with a history of anaphylaxis immediately after the administration of anesthetics lidocaine, propofol, and rocuronium to perform endoscopic sinus surgery 2 years before. The skin test showed a positive reaction to rocuronium and cis-atracurium. We induced general anesthesia without using NMBAs after inducing airway anesthesia with lidocaine (transtracheal injection and superior laryngeal nerve block). Deep general anesthesia was maintained with end-tidal 4 vol% sevoflurane. Hypotension was treated with phenylephrine infusion. The operation condition was excellent, and patient recovered without complications after surgery. Airway anesthesia with local anesthetics may be helpful when we cannot use NMBAs for any reason, including hypersensitivity to NMBA and surgery that needs neuromuscular monitoring.

General anesthesia has been developed in dentistry as a type of management technique to sedate patients who may be uncontrollable or require medical consideration. However, emergency treatment for controlling pain before general anesthesia could be required due to the time for medical evaluation for general anesthesia. There is a greater possibility of developing complications under extended waiting period. A disabled patient who needs dental treatment under general anesthesia underwent pretreatment with intramuscular injection of midazolam and $N_2O-O_2$ inhalation sedation in these cases report.

Pulseless electrical activity (PEA) is a clinical condition characterized by unresponsiveness and lack of palpable pulse in the presence of organized cardiac electrical activity and is caused by a profound cardiovascular insult (e.g., severe prolonged hypoxia or acidosis, extreme hypovolemia, or flow-restricting pulmonary embolus). Amyotrophic lateral sclerosis (ALS) is a disease that is characterized by progressive degeneration of all levels of the motor nervous system. Damage to the respiratory system and weakness of the muscles may increase the likelihood of an emergency situation occurring in patients with ALS while under general anesthesia. We report a case of PEA during the induction of general anesthesia in a patient with ALS who presented for dental treatment and discuss the causes of PEA and necessary considerations for general anesthesia in patients with ALS.

Local anesthesia is administered to reduce pain during dental treatments, but may itself cause pain and contribute to increased dental fear. Computer-controlled local anesthetic delivery (CCLAD) is one the method to reduce patient pain during local anesthesia; it is a device that slowly administers anesthetics by using a computerized device to control the injection speed. This literature review aims to provide an objective assessment of the usefulness of CCLAD for controlling pain by reviewing papers published to date that have used CCLAD.

Background: Sedation or outpatient general anesthesia is a necessary method for a successful dental treatment for children and the disabled who have a difficulty of cooperation. The aim of this study was to assess the patients who had dental treatment under sedation or outpatient general anesthesia at department of pediatric dentistry, Chonnam national university dental hospital and Gwangju dental clinic for the disabled. Methods: 875 patients who had sedation from January 2009 to September 2013 and 88 patients who had outpatient general anesthesia after May 2011 were assessed for this study. Patient's distribution and treatment patterns were examined. Results: The number of patients has been increasing in both sedation and outpatient general anesthesia. In case of sedation, the proportion of male patients was higher and 4-6 years age group was the highest. Most patients have resided in Gwangju buk-gu and the percentage of restorative treatment was the highest. In case of outpatient general anesthesia, the proportion of male patients was higher than that of sedation. Two groups, 10-19 and 20-29 years age, consisted most of patient. Most patients have resided in Gwangju buk-gu and Jeollanam-do, and the percentage of periodontic and preventive treatment was the highest. Conclusions: Sedation or outpatient general anesthesia for dental treatment has been increasing for children and the disabled who have a difficulty of cooperation. Therefore, it is important to improve treatment environment under sedation and general anesthesia through continuous research and studies.

The purpose of this study was to analyze the dental treatment of patients with disabilities, especially according to the frequency of general anesthesia, and to propose the improvements in oral care. The subjects of the present study were 85 patients including age, sex, medical condition, dental treatment and the number of general anesthesia. The patients were divided into regular and irregular check groups according to their follow-up patterns. These two groups were compared for the frequency of general anesthesia and the type of repeated treatment. The results showed that restorative treatment was superior in numbers under first visit of general anesthesia. And more general anesthesia was performed in the irregular recall check group compared with the regular recall check group. This survey suggest that easy access to a dental clinic and the convenience of treatment is needed. On the other hand, there is a time limit on the dental care for disabilities by the dentist. Therefore oral care training program should be simultaneously provided for parents to improve the efficiency of dental care at home. In conclusion, efforts should be made for more comprehensive and effective dental care including regular recall check and preventive home care for disabilities.

This study describes the characteristics of patient receiving comprehensive dental treatment under general anesthesia at the pediatric dentistry of Chosun University dental hospital in Gwangju, between August 2004 and March 2008. The conclusion runs as follows : 1. Most patients(64.8%) were young (under 10 years of age) and mean age was 8.6 years. 2. The primary reason(31.1%) why they chose general anesthesia was lack of child's cooperation (normal but unmanageable). Following in order are mental retardation, Autism and cerebral palsy etc. 3. Resin restorations were performed most frequently(87.8%) followed by pulp treatment, preformed crown, extraction and sealant. 4. It takes 3 hours 10 minutes for general anesthesia on the average. The mean treatment time under general anesthesia was 2 hours 52 minutes. 5. 29 children(39.7%) visited again after general anesthesia for recall check.
