Severe Hypotension after Thoracic Paravertebral Block due to Epidural Spread: A Case Report

Ji Seon Chae,Dae Hyun Kim,Jeong Ae Lim,Joon Lee 대한통증연구학회 2020 International Journal of Pain Vol.11 No.2

We report a case of severe hypotension that occurred subsequent to a left thoracic paravertebral block (TPVB) in a 65-year-old man who underwent a thoracotomy one month before presentation. In addition to hypotension, he experienced motor weakness in his left leg. The patient was treated, stabilized, and eventually discharged. Two months after the first procedure, when the TPVB was to be repeated, the cause of the hypotension was identified as an inadvertent epidural spread. This spread was determined by injecting contrast medium into the respective thoracic paravertebral spaces prior to the local anesthetic injection. Once the cause of hypotension was identified, effective remedial measures could be taken. While performing the TPVB, we should be mindful of the spread of the local anesthetic drugs into the epidural or other spaces, and of the associated complications.

Facet Joint Versus Transforaminal Epidural Steroid Injections in Patients With Cervical Radicular Pain due to Foraminal Stenosis: A Retrospective Comparative Study

Ji Seon Chae,Won-joong Kim,Mi Jin Jue 대한의학회 2022 Journal of Korean medical science Vol.37 No.25

Background: A cervical transforaminal epidural (TFE) steroid injection is a useful treatment option for cervical radicular pain, but it carries a small risk of catastrophic complications. Several studies have reported that cervical facet joint (FJ) steroid injection can reduce cervical radicular pain through an indirect epidural spread. The aim of this retrospective comparative study was to evaluate the pain scores and functional disability in subjects receiving cervical FJ or TFE steroid injection for the treatment of cervical radicular pain due to foraminal stenosis (FS). Methods: We selected 278 patients 18 years of age and older who underwent cervical FJ (n = 130) or TFE (n= 148) steroid injection for cervical radicular pain. The primary outcomes included pain scores and functional disability during hospital visits one, three, and six months after the initial injection. Secondary outcomes were the proportion of responders and Medication Quantification Scale (MQS) scores. Adverse events and variables correlating with effectiveness one month after the initial injection were also evaluated. Results: The Numeric Rating Scale and Neck Disability Index scores showed a significant improvement one, three, and six months after the initial injection in both groups, with no significant differences between the groups. No significant differences were observed in the success rates of the procedure one, three, and six months after the initial injection for either group. There were no significant differences in MQS between the groups during the followup period. Univariate and multivariate logistic regression analyses revealed that the injection method, age, sex, number of injections, FS severity, MQS, pain duration, and the presence of cervical disc herniation were not independent predictors of treatment success. Conclusion: The efficacy of FJ steroid injection may not be inferior to that of TFE steroid injection in patients with cervical radicular pain due to FS.

Patients with Klippel-Feil syndrome require much attention during anesthesia because of congenital abnormalities in head and neck regions and the high probability of neurological damage from cervical spine instability during endotracheal intubation. We report a case of successful endotracheal intubation using a videolaryngoscope in a patient with Klippel-Feil syndrome who experienced difficult transnasal intubation.

Effects of Local Anesthetics With or Without Steroids in High-Volume Transforaminal Epidural Blocks for Lumbar Disc Herniation: A Randomized, Double-Blind, Controlled Trial

Ji Seon Chae,Won-joong Kim,Se Hee Choi 대한의학회 2022 Journal of Korean medical science Vol.37 No.17

Background: Lumbar transforaminal epidural block (TFEB) is an effective treatment modality for radicular pain due to lumbar disc herniation (LDH). The addition of steroids is more effective than local anesthetic alone in TFEBs for patients with LDH. Moreover, the efficacy of TFEBs has been reported to be positively correlated with the volume of injectate. We hypothesized that high-volume TFEBs without steroids effectively alleviate axial back and radicular pain associated with LDH. This study compared the efficacy of high-volume TFEBs with vs. without steroids for the management of the axial and radicular pain caused by LDH. Methods: A total of 54 patients were randomly assigned to either group L or group D. Patients in group L received 8-mL injections of 0.33% lidocaine only. Patients in group D received 8-mL injections of 0.33% lidocaine with 5 mg of dexamethasone. The primary outcomes were pain intensity at baseline and 4 weeks after the procedure. The secondary outcomes included the change of functional disability between baseline and 4 weeks after the procedure, pain scores during injection, and adverse effects. Results: Both groups showed a significant reduction in axial and radicular pain and improvement in the functional status at the outpatient visit 4 weeks after TFEB. However, there were no significant differences between the groups in terms of changes in back pain (10.00 [20.00] vs. 10.00 [22.50]; P = 0.896) or radicular pain (5.00 [20.00] vs. 10.00 [12.50]; P = 0.871). Conclusion: High-volume TFEBs with and without steroid administration yielded similar significant pain reductions and functional improvements among LDH patients 4 weeks after the procedure.

Oh, Ji Seon,Kim, Duri,Chae, Seung Ho,Oh, Seungjoo,Yoo, Seong Tae,Kim, Haebeen,Ryu, Ji Heon The Korean Electrochemical Society 2019 Journal of electrochemical science and technology Vol.10 No.3

Sn-Cu alloy powders were prepared via a simple chemical reduction method for the negative electrode materials in lithiumion batteries. The addition of Cu can suppress the growth of Sn particles during synthetic process. Furthermore, the Cu also acts as a matrix phase against the volume change during cycling. With increasing amount of the Cu, a stable $Cu_6Sn_5$ phase formed in the Sn-Cu alloy and its cycle performance greatly enhanced depending on the Cu content. To promote the generation of the $Cu_6Sn_5$ phase, the synthesis temperature is raised to $60-100^{\circ}C$ from the ambient temperature. The Sn-Cu alloy powders prepared at elevated temperatures showed remarkable cycle performances. The Sn-Cu alloy powder obtained at $60^{\circ}C$ exhibited a significantly high volumetric capacity of over 2,000 mAh/cc at the 50th cycle.

국내외 지역 정부들은 지역의 음식을 관광지 선택의 핵심 요인으로 인식하고 적극적인 홍보에 나서고 있다. 실제로 음식문화는 지역의 브랜드 정체성을 드러내는 핵심 적이고 매력적인 지역문화브랜드 커뮤니케이션 수단이자 지역 관광 활성화의 수단이 될 수 있다. 그렇다면 지역은 각 지역의 음식문화를 지역문화브랜딩 차원에서 표출하기 위하여 어떠한 구성요소까지를 포함시키고 있을까? 본 연구는 전주, 청두, 교토 등세 지역의 공식 홈페이지 속에 나타난 음식문화 관련 담화의 구조와 내용분석을 통해 지역문화브랜딩의 일환으로서의 음식문화브랜드의 핵심 구성요소를 도출하고 그 정체성 역시 파악해보고자 하였다. 연구결과, 본 연구는 3개 지역이 공통적으로 음식문화브랜드의 핵심적 구성요소를 “식재료”, “음식”, “이벤트”, “음식 공간”, “문화시설”, “레시피”, “커뮤니케이션”, “특산물” 등 8가지로 범주화하여 커뮤니케이션하고 있음을 확인할 수 있었다. 또한, 본 연구는 음식문화브랜드를 지자체 지역문화브랜딩의 핵심 요소로 간주하면서, 8가지의 지역음식문화 핵심 구성요소의 문화적 지향가치 역시 정리해보고자 시도하였다. 연구 결과, 식재료와 음식이라는 음식문화의 핵심 구성요소는 “계획” 영역의 지향가치와 부합하며, 이벤트와 음식 공간은 “쾌락” 영역의 지향가치와 부합하고, 문화시설과 레시피는 “정보” 영역의 지향가치와 부합하며, 커뮤니케이션과 특산물은 “비전” 영역의 지향가치와 부합함을 파악함으로써 지역의 음식문화브랜드 8각형 구조를 도출할 수 있었다. Domestic and overseas governments recognize regional food, as a key factor in the selection of tourist attractions and are actively promoting them. Indeed, food culture can be a means of revitalizing regional tourism as well as a key and attractive regional cultural brand communication tool that reveals the region’s brand identity. What components should be included in the region to express the regional food culture in terms of region’s cultural branding? The purpose of this study is to identify the key components of food culture brand as a part of regions’ cultural branding through the structure and content analysis of food culture related contents in the official web sites of Jeonju, Chengdu and Kyoto. In this study, it was confirmed that the three cities categorized the core components of the food culture brand into eight categories as “food ingredients”, “food”, “events”, “food spaces”, “cultural facilities”, “recipe”, “communication” and “regional product”. In addition, this study attempted to summarize the core values of the eight regional food culture components while considering the food culture brand as a core element of regional culture branding. This study was able to derive the octagonal key components structure of regional food culture brand. This study confirms that the food ingredient and food are consistent with the oriented values of the “Project” domain, the events and food spaces are consistent with the oriented values of the “Euphory” domain, cultural facilities and recipe are consistent with the oriented value of the “Information” domain, and the communication and regional products were found to be consistent with the oriented values of the “Vision” area.

섬 지역의 음식문화 커뮤니케이션 전략 연구 ― 신안군·완도군·진도군 홈페이지의 특산물 담화를 중심으로 ―

채지선 ( Chae Ji-seon ),전형연 ( Jeon Hyeong-yeon ) 전남대학교 호남학연구원 2021 호남학 Vol.- No.70

바다에 둘러싸인 화려한 풍광과 풍부한 해산물에 기반한 음식문화는 섬 지역 관광의 핵심 요소이다. 이에 본 연구는 섬을 많이 보유한 전남의 섬 지역 중에서 보유한 섬의 수가 가장 많은 도서군이며, 지역민의 인구수 역시 가장 많은 신안군, 완도군, 진도군 등의 기초자치단체를 연구 대상으로 삼아 섬 지역의 음식문화 커뮤니케이션 전략 현황을 분석해보았다. 분석 결과, 세 지역 모두 지자체 공식 홈페이지 및 문화관광 홈페이지 구조 분석을 통해 본 연구는 ‘특산물’ 관련 담화를 섬 지역의 음식문화 커뮤니케이션을 위한 핵심 요소로 고려하고 있음을 확인할 수 있었다. 또한, 지역이 홈페이지를 통해 표출하고 있는 ‘특산물’ 담화의 이미지 기호와 텍스트 기호의 분석을 통해 본 연구는 섬 지역 ‘음식문화’의 공통적 정체성과 지향 가치는 물론 각 지역의 음식문화 정체성 및 지향 가치 역시 파악할 수 있었다. 즉, 신안군, 완도군, 진도군 공통으로 섬 지역 특산물의 /우수성/, /환경성/, /기능성/, /정보성/ 등의 가치를 지향하고 있음을 확인할 수 있었다. 또한, 각 지역의 음식문화 정체성 차원에서는 신안군의 경우 /효용성/, /미학성/, /감각성/을 바탕으로 한 ‘조리된 요리 지향성’을 파악할 수 있었으며, 완도군의 경우에는 바다에서 그대로 건져 올린 수산물의 /생동성/과 /바다성/을 기반으로 한 ‘자연 그대로의 신선성’을 확인할 수 있었고, 진도군의 경우에는 특산물의 /우수성/, /기능성/을 바탕으로 한 ‘해조류의 상품성’ 지향을 확인할 수 있었다. 이와 같은 연구 결과를 바탕으로 본 연구는 섬 지역 역시 각 지역의 음식문화와 관련한 차별적인 브랜드 가치를 지향해야 하며, 이를 위한 커뮤니케이션 전략 역시 심층적으로 고민해야 한다는 시사점을 얻을 수 있었다. Spectacular scenery surrounded by the sea and food culture based on abundant seafood are key elements of island tourism. This study analyzed the current status of food culture communication strategies of the regional governments such as Shinan-gun, Wando-gun and Jindo-gun, which have the largest number of islands among the island regions of Jeollanam-do and have a large population of regional residents. According to an analysis of the structure of the official website of regional governments and cultural tourism in the three island regions, it is confirmed that the discourses on “special products” are mainly being discussed in food culture communication in the island regions. In addition, this study was able to identify not only the common identity and orientation value of “food culture” in the island regions, but also the identity and orientation value of “food culture” in each region through an analysis of the image signs and text signs of the “special product” discourses expressed by the region on the homepage. As a result, it can be seen that Sinan-gun, Wando-gun, and Jindo-gun all aim for the values of /excellence/, /environmental/, /functional/ and /information/. Also, in terms of the food culture identity of each region, Shinan-gun aims for “cooked dishes” based on /utility/, /aesthetic/ and /sensibility/, and the characteristic of Wando-gun is the “natural freshness” based on the /vitality/ and /marine/ of marine products recovered from the sea, and the characteristic of Jindo-gun is the “commercialization of seaweed” based on the /excellence/ and /functionality/ of special products. Based on these findings, this study suggests that the island regions should pursue differentiated brand values related to the food culture of each region, and also considered the communication strategies in depth.
