Recently dental emergency patients tend to increase and diversify because of increased living quality and acknowledgement of health care. We performed this study to understand the pattern of dental emergency and perform the adequate diagnosis and treatment. From August 1998 to July 1999, we inverstigated the rate of dental emergency, distribution according to disease pattern, monthly distribution, and types of emergency treatment from all the emergency patients that visited emergency medicine of Daejin Medical Center, Jesaeng Hospital. There were 266 dental patients(0.978%) from total 27,192 emergency patients. Types of emergency situations included lip lacerations, teeth fracture, teeth missing or avulsion, TMJ contusion, mandible fracture, tongue laceration, toothache, teeth luxation, and so forth. Dental emergency had highest frequency in July. The most common treatments included primary closure of soft tissue lacerations, fixations of luxated teeth and medications.

Background: There is some concern that the administration of epidural analgesia for pain relief during labor increases the likelihood of cesarean delivery. But, several investigators showed a decrease in the rate of emergency cesarean delivery after epidural analgesia. The purpose of this study was to compare the emergency cesarean rate between the two groups with and without epidural analgesia. Methods: We reviewed retrospectively the medical records for 7846 parturients admitted our hospital between January 1, 1995 and December 31, 1996 and whose attending physician anticipated a normal labor and vaginal delivery. The number of parturients with epidural analgesia using 0.25% bupivacaine with fentanyl were 2839 and parturients without epidural analgesia were 5017. Results: An administration of epidural analgesia was not associated with the incidence of cesarean rate. 149 (5.25%) of 2839 parturients in epidural group and 371 (7.31%) of 5017 parturients in non-epidural group underwent emergency cesarean section. Conclusions: Our retrospective study has shown that an administration of epidural analgesia neither decrease nor increase in the rate of emergency cesarean delivery when compared with a non-epidural analgesia.

Purpose : The present study was designed to provide basic data for advanced pre-hospital airway management by comparing the insertion time and success rate between laryngeal tube suction II (LTS II) and laryngeal mask airway (LMA) in a manikin. Methods : A total of 32 participants were novice users to both of devices among paramedic students. After taking the introductory lecture and demonstrations, the participants made an attempt to insert the LTS II and LMA to compare the insertion time and success rate. They marked the easiness of insertion of the score ranged from 1 to 10 score scale and preference of the two devices. Results : The insertion time of the LTS II was significantly shorter than that of the LMA (p =.000). There was no significant difference between LTS II and LMA in the success rate. In the easiness of insertion, the score of LTS II $(8.47{\pm}1.41score)$ was significantly higher than that of LMA $(7.19{\pm}1.98score)$(p =.001). The preference of LTS II (75%) was much higher than that of LMA (25%). Conclusion : The manikin study data showed that the LTS II may be a good alternative airway device for providing and maintaining a patent airway.

Purpose: On November 15, 2012, sales of OTC (Over-The-Counter) drugs began at convenience stores, which changed the accessibility of some drugs. As a result, the exposure and access patterns of these drugs could have changed. In this study, we reviewed the changes in the characteristics of drug poisoning patients because of the reposition of nonprescription drugs according to the revised Pharmaceutical Affairs Act. Methods: A retrospective study was conducted to evaluate changes in characteristics of drug poisoning patients between 2008 and 2016. A registry was developed by an emergency medical center in a local tertiary teaching hospital, and patients who visited the center were enrolled in this registry. We compared two periods, from 2008 to 2012 (Pre OTC) and from 2013 to 2016 (Post OTC), for type of intoxicant, time from poisoning to visiting the emergency center, intention, psychiatric history, previous suicidal attempt, alcohol status, and emergency room outcomes. The primary outcome was the number of patients who took acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Secondary outcomes were ICU admission rate, mortality rate, and number of patients who visited the ER when the pharmacy was closed after taking acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Results: Among 1,564 patients, 945 and 619 patients visited the emergency room during pre and post OTC periods. The number of patients with acetaminophen and NSAIDs poisoning decreased from 9.2% to 6.1% (p=0.016). The ICU admission rate and mortality rate in the emergency room did not show significant results in the relevant patient groups, and so was the number of patients visiting ER when the pharmacy was closed taking acetaminophen and NSAIDs. Conclusion: Despite the sales of nonprescription drugs at convenience stores, the number of acetaminophen and NSAIDs poisoning patients decreased.

Purpose: The aim of this study was to identify clinical outcome and characteristics of trauma patients via emergency medical services (EMS). Methods: Medical records of the trauma patients visiting the emergency department were retrospectively collected and analyzed from January 2015 to June 2016 in the single institution. Of 529 registered patients, 371 patients were transported by - were enrolled. The parameters including age, gender, injury mechanism, Glasgow coma scale on arrival, presence of shock (systemic blood pressure <90 mmHg) on arrival, time to arrival from accident to emergency room (ER), need for emergency procedures such as operation or angioembolization, need for intensive care unit (ICU) admission, injury severity score (ISS), the trauma and injury severity score, revised trauma score (RTS), length of stay, and mortality rate were collected. The SAS version 9.4 (SAS Institute, Cary, NC, USA) was used for the data analysis. Results: Arrival time from the field to the ER was significantly shorter in EMS group. However, overall outcomes including mortalities, length of stay in the ICU and hospital were same between both groups. Age, ISS, RTS, and injury mechanisms were significantly different in both groups. ISS, RTS, and age showed significant influence on mortality statistically (p<0.05). Conclusions: The time to arrival of EMS was fast but had no effect on length of hospital stay, mortality rate. Further research that incorporates pre-hospital factors influence clinical outcomes should be conducted to evaluate the effectiveness of such a system in trauma care of Korea.

This study proposes a remote monitoring of patients and emergency notification system with a camera and pulse wave sensor for U-Healthcare. The proposed system is a server client model based U-Healthcare system which consists of wireless clients that have micro-controller, embedded-board for patient status monitoring and a remote management server. The remote management server observes the change of pulse wave data individually in real-time sent from the clients that is to be remote-monitored based on the pulse wave data stored by users and divides them into caution section and emergency section. When the pulse wave data of a user enters an emergency situation, the administrator can make a decision based on the real-time image information and pulse rate variability. When the status of the monitored patient enters the emergency section, the proposed U-healthcare system notifies the administrator and relevant institutions. An experiment was conducted to demonstrate the pulse wave recognition of the proposed system.

Purpose:Plaster splints are routinely performed in the Emergency Department (ED) and avoidable complications such as skin ulcerations and fracture instability arise mainly due to improper techniques. Despite its frequent use, there is often no formal training on the fundamental principles of plaster splint application for a medical officer rotating through ED. We aim to use Quality Improvement (QI) methodology to reduce number of incorrect plaster splint application to improve overall patient care via a bundled educational solution. Methods: We initiated a QI program implementing concepts derived from the Institute for Healthcare Improvement models, including Plan-Do-Study-Act (PDSA) cycles, to decrease the rate of incorrect plaster splint application. A bundled education solution consisting of three sequential interventions (practical teaching session, online video lecture and quick reference cards) were formulated to specifically target critical factors that had been identified as the cause of incorrect plaster splints in ED. Results: With the QI intervention, our overall rate of incorrect plaster splints was reduced from 84.1% to 68.6% over a 6-month period. Conclusion: Following the QI project implementation of the bundled educational solution, there has been a sustained reduction in incorrect plaster splints application. The continuation of the training program also ensures the sustainability of our efforts in ED.
