Using nasal cannula for sevoflurane deep sedation in emergency dental treatment
Kim, Jongbin,Yoo, Seunghoon,Kim, Jongsoo,Kim, Seungoh The Korean Dental Society of Anesthsiology 2015 Journal of Dental Anesthesia and Pain Medicine Vol.15 No.1
Background: Emergency room doctors run into difficulties in treating injured pediatric patients because usually they fell into panic after trauma. In these situation, deep sedation with sevoflurane is fully recommendable method. The conventional way can interrupt common dental treatment procedure. Methods: In the present study, nasal cannula was used for sevoflurane deep sedation in 11 dental emergency treatment. Age ranged from 0 to 3 years old (average of 1.8 years). Results: Treatment duration was from 10 to 35 minutes (average of 16.7 minutes). Average duration of sedation was 25.5 minutes ranging from 15 to 45 minutes. Conclusions: It has advantages to use nasal cannula for sevoflurane deep sedation rather than conventional intubation; saves time and secures good operation field.

A Tenebrio molitor larva that is called mealworm is widely used as feed for raising a pet. Also, it is the insect that would be produced as the edible food for human. For these reasons, many researchers are revealing about physiologic characteristic of Tenebrio molitor to make good use of it. However, morphological characteristic of different larval stage is not specifically indicated and researchers have different opinions about the average number of Tenebrio molitor’s instar until now. This study, therefore, was carried out to examine the physiological and morphological characteristics of Tenebrio molitor larva in different larval stages, and the average number of Tenebrio molitor’s instar. As a result, all of the Tenebrio molitor larvae had 7~8 days during their incubation period and 3~4 days during the 1st instar period. After the 1st instar, there were comparatively large differences in the number of days in each instar. Before emergence, most of the larvae comparatively showed 15th~17th instars, particularly, the largest rate of pupae (28.83%) was observed in the 17th instar. In terms of the body length of each Tenebrio molitor larval stage, the body length was gradually increased by the 17th instar. Beyond the 17th instar, however, the body length was smaller than 17th instar. In the 1st instar, the larva had white color, and the color gradually changed into brown from the 2nd instar. Through this study, we could identify the accurate incubation period, 1st instar period, the average number of instar, body length and the color change in different larval stages. These results would be used as a fundamental data for further study about the physiological and morphological characteristic of each instar period.
The alternative of oral sedation for pediatric dental care
Kim, Jongbin,Kim, Seungoh,Lee, Deok-Won,Ryu, Dae-Seung The Korean Dental Society of Anesthsiology 2015 Journal of Dental Anesthesia and Pain Medicine Vol.15 No.1
In pediatric dentistry, chloral hydrate is habitually selected for sedation of uncooperative children. Although chloral hydrate has been used for decades, various adverse effects are reported and necessity for new alternative drugs has increased. Dexmedetomidine was approved by FDA for sedation at intensive care units (ICU) in 1999. Compared to conventional sedative drugs, dexmedetomidine has not only analgesic and sedative effects but also it barely suppresses the respiratory system. Due to these characteristics, dexmedetomidine is known as safe sedative drug for children and elderly patients. Furthermore, approved by KFDA in 2010 in Korea, the frequency of sedation using dexmedetomidine is increasing. However, due to its intravenous administration method, it was difficult to apply in pediatric dentistry. Recently, intranasal administration method was introduced which might be a new possible alternative of oral sedation. In this study, we compare the mechanisms, pros and cons of chloral hydrate and dexmedetomidine, introducing new possibilities.
Universal Overdrive Technology with Third-Order Approximation: LC Dependency
Jongbin Kim,Youngmin Cho,Achintya Bhowmik,Seung-Woo Lee 대한전자공학회 2010 ICEIC:International Conference on Electronics, Inf Vol.1 No.1
In this work, we examine liquid crystal material dependency of our overdrive (OD) technology with a third-order approximation. For the examination, we used eleven LCD panels that adopt slow TN, fast TN and IPS. This work reports that any third-order approximation optimized at a certain LC panel can be applied to the other LC panels by adjusting only one parameter. Consequently, our OD technology enables PC users to tune their LCD panel’s response characteristics by adjusting one value.
