The purpose of this retrospective study is to investigate the effects of conscious sedation in an outpatient setting. Data from 292 patients (154 males, 138 females), sedated for minor oral surgery, were studied using various parameters including age and sex distribution, as well as according to procedures and each drug group. Results show that this intravenous conscious sedation technique is a safe and effective method of controlling behaviour, but one has to be prepared to deal with any emergencies or complications. The specific results are as follows: 1. Most procedures (265/292) were used to Valium mixed with Demerol and Midazolam mixed with Demerol. 2. Valium revealed a high incidence of pain upon injection and symptoms limited to daily activity and thrombophlebitis. 3. Nausea and vomiting manifested in the procedure using Demerol. 4. The patient manifested comfort similar in response to the same drugs used in another treatment.

Purpose : On outpatient facilities, our sedation protocol focuses on the intermittent bolus injections of midazolam intravenously, according to patient's and operator's needs during the dental treatment. This multicenter retrospective study was aimed to prove the efficiency and safety of our sedation protocol. Patients and Methods : In three centers using the same outpatient sedation protocol for dental treatment (Division of Oral and Maxillofacial Surgery/Department of Dentistry in Hanyang University Medical Center, S-plant Dental Hospital. and Grand Oral and Maxillofacial Surgery), total 937 patients had various dental treatments under intravenous conscious sedations with independent patient monitoring from March 2006 to March 2009. By reviewing charts, we analyzed the results of sedation and dental treatment, retrospectively. Results : Our sedation protocol had no severe postoperative complications requiring admission. while showing good compatibility with almost all dental treatments, with acceptable satisfaction of both patients and operators. Conclusion : We assure that our sedation protocol can be used efficiently and safely on routine outpatient basis. We also hope that this study will provide the concrete concepts to common dental practitioners, who desire to perform sedation for dental treatment.

Chloral hydrate is the oldest and most common sedative drug used in moderate sedation for pediatric dental patients. Hence, the purpose of this article is to review the safety and possible adverse events of this drug when used for pediatric dental treatment. A bibliographic search in PubMed, MEDLINE, Cochrane Library and KMbase, KISS, DBpia, KoreaMed, and RISS databases was performed. Using the keywords "dental sedation," "chloral hydrate," and "children or adolescent," 512 scientific articles were found. Subsequently, 183 studies were individually assessed for their suitability for inclusion in this literature review. Altogether, 24 studies were selected. They included 12 cases of death before, during, or after chloral hydrate sedation for dental treatment, majorly due to dosing error and use of multiple sedatives. Additionally, intraoperative adverse events were mostly respiratory problems such as hypoxia and apnea, but most events were temporary. After treatment, prolonged sedation, including excessive sleep and less activity were the most common postoperative adverse events, and even death cases were reported. Despite the wide acceptance of chloral hydrate as a sedative-hypnotic agent, the risk of adverse events and adequate dose should be of great concern when using it for pediatric dental sedation.

Background: It is imperative that adequate sedation level should be maintained for safe and effective dental sedation. Cerebral state index (CSI) is a empirically derived parameter calculated from the processed electroencephalography (EEG). We investigated whether CSI can be used as a sedation depth indicator. Methods: We continuously recorded CSI and bispectral index (BIS) values from 10 healthy children aged 3.6 yr undergoing dental sedation. We also evaluated sedation level using the Modified Observer's Assessment of Alertness/Sedation (MOAA/S). The correlation between CSI and BIS, or CSI and sedation score were sought a regression analysis. Results: There were good linearity between CSI values and sedation score. (r = 0.916, P < 0.001) The paired CSI and BIS values showed a significant correlation between the two values. (r = 0.895, P < 0.001) The difference between CSI and BIS values was not statistically significant at deep and conscious sedative levels. Conclusions: The CSI monitor can be easy to monitor sedation depth during dental sedation for children.

Background: Sevoflurane, a rotatively new inhalational anesthetic. has non-pungent odor and is less reluctant to pediatric patients. The purpose of this study is to examine the feasibility of sevoflurane in inhalational sedation instead of the nitrous oxide for short and simple dental treatments in pediatric patients. Patients and Methods: Fifteen healthy children, whose dental treatment was abandoned due to their little or no cooperation, were selected with their caregivers' written permission. Deep sedation was induced and maintained with oxygen and 1-5% sevoflufane via specially designed nasal mask. Blood pressure, heart rate, oxygen saturation, and electrocardiogram were monitored at 3-nin interval. A dental anesthesiologist, who was independent of dental treatments, was wholly responsible for the sedation procedure. Post-sedation complications and operator's and caregiver's acceptability of this type of inhalational sedation were also investigated. Results: The systolic and diastolic blood pressure, heart rate, and oxygen saturation was significantly depressed during the deep sedation using sevoflurane (P < 0.05). No severe post-sedation complications were found, however, bradycardia was reported in 3 patients. Almost all the operators and caregivers answered that they would adapt this sedation procedure again if possible. Conclusion: In this study, inhalational deep sedation using sevoflurane for dental treatments was found to be very useful. Furthermore, the application of sevoflurane to conscious sedation for pediatric and adult dental patients should be added.

Purpose: Various publications on the use of sedation and anesthesia for diagnostic procedures in children have demonstrated that no ideal agent is available. Although propofol has been widely used for sedation during esophagogastroduodenoscopy in children, adverse events including hypoxia and hypotension, are concerns in propofol-based sedation. Propofol is used in combination with other sedatives in order to reduce potential complications. We aimed to analyze whether the administration of midazolam would improve the safety and efficacy of propofol-based sedation in diagnostic esophagogastroduodenoscopies in children. Methods: We retrospectively reviewed the hospital records of children who underwent diagnostic esophagogastroduodenoscopies during a 30-month period. Demographic characteristics, vital signs, medication dosages, induction times, sedation times, recovery times, and any complications observed, were examined. Results: Baseline characteristics did not differ between the midazolam-propofol and propofol alone groups. No differences were observed between the two groups in terms of induction times, sedation times, recovery times, or the proportion of satisfactory endoscopist responses. No major procedural complications, such as cardiac arrest, apnea, or laryngospasm, occurred in any case. However, minor complications developed in 22 patients (10.7%), 17 (16.2%) in the midazolam-propofol group and five (5.0%) in the propofol alone group (p=0.010). Conclusion: The sedation protocol with propofol was safe and efficient. The administration of midazolam provided no additional benefit in propofol-based sedation.

Prader-Willi syndrome (PWS) is a rare genetic disorder reported rarely in dentistry. Dental practitioners should know the features of PWS because affected patients have a variety of dental symptoms. The current report describes a case of PWS. An 18-year-old male patient presented with traumatic injuries. Initial emergency treatments were performed under sedation, and further treatments were conducted under general anesthesia. After adequate healing, periodic follow-up and dietary management according to the patient's age and nutritional phase were recommended. Dental management of PWS patients consists of active preventive measures in addition to dietary consultation according to age and nutritional phase.

The first clinical application of nitrous oxide ($N_2O$) was in 1844, by an American dentist named Horace Wells who used it to control pain during tooth extraction. Since then, $N_2O$ has shared a 170-year history with modern dental anesthesia. $N_2O$, an odorless and colorless gas, is very appealing as a sedative owing to its anxiolytic, analgesic, and amnestic properties, rapid onset and recovery, and, in particular, needle-free application. Numerous studies have reported that $N_2O$ can be used safely and effectively as a procedural sedation and analgesia (PSA) agent. However, $N_2O$ can lead to the irreversible inactivation of vitamin B12, which is essential for humans; although rare, this can be fatal in some patients.
