Management of intractable oronasal bleeding using Sengstaken-Blakemore tubes in patients with facial trauma: a case series and technical notes

Objective@#Intractable massive oronasal bleeding can become a life-threatening condition. The success rate of conventional bleeding control methods other than transarterial embolization (TAE) is not expected to be high. We investigated the efficacy of Sengstaken-Blakemore tube (SBT) balloon tamponade in patients with sustained and intractable oronasal bleeding secondary to facial injury. @*Methods@#This study is a retrospective chart review from traumatic patients with sustained and intractable oronasal bleeding who were admitted to the emergency center of Ajou University Hospital and Soonchunhyang University Bucheon Hospital from January 2014 to December 2016. @*Results@#Twelve patients were included in the study, of whom nine (75%) were male. The median age was 31 years (range, 20–73 years). Bleeding was controlled in 11 of the 12 patients (91.7%) either temporarily or definitively. One patient without hemostasis underwent TAE. TAE was performed in an additional three patients out of the 11 patients with hemostasis who experienced continued nasal bleeding after the removal of SBTs. There were no complications from performing the procedure. @*Conclusion@#Using SBTs as a hemostatic tool will aid patients with life-threatening intractable oronasal bleeding. Furthermore, this method may be used in patients with continual and intractable oronasal bleeding after facial trauma as a bridging procedure from the emergency department or the intensive care unit to the interventional radiology.

Characteristics and outcomes of public bath-related out-of-hospital cardiac arrests in South Korea

Objective@#To analyze the differences in characteristics and outcomes between public bath (PB)- related and non-PB-related out-of-hospital cardiac arrest (OHCA) patients in South Korea. @*Methods@#We performed a retrospective observational analysis of collected data from the Smart Advanced Cardiac Life Support (SALS) registry between September 2015 and December 2018. We included adult OHCA patients (aged >18 years) with presumed OHCA of non-traumatic etiology who were attended by dispatched emergency medical services. SALS is a field advanced life support with smartphone-based direct medical direction. The primary outcome was the survival to discharge rate measured at the time of discharge. @*Results@#Of 38,995 cardiac arrest patients enrolled in the SALS registry, 11,889 were included in the final analysis. In total, 263 OHCAs occurred in PBs. Male sex and bystander cardiopulmonary resuscitation proportions appeared to be higher among PB patients than among non-PB patients. Percentages for shockable rhythm, witnessed rate, and number of underlying disease were lower in the PB group than in the non-PB group. Prehospital return of spontaneous circulation (11.4% vs. 19.5%, P=0.001), survival to discharge (2.3% vs. 9.9%, P<0.001), and favorable neurologic outcome (1.9% vs. 5.8%, P=0.007) in PB patients were significantly poorer than those in non-PB patients. @*Conclusion@#Patient characteristics and emergency medical services factors differed between PB and non-PB patients. All outcomes of PB-related OHCA were poorer than those of non-PB-related OHCA. Further treatment strategies should be developed to improve the outcomes of PBrelated cardiac arrest.

Analysis of the 119 emergency situation control center usage including dispatcher-assisted cardiopulmonary resuscitation instructions

OBJECTIVE: Analyses of the status of 119 emergency situation control center (119 ESCC) usage are lacking. Therefore, this study investigated the status of the 119 ESCC usage, including dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) instructions. METHODS: The emergency activity daily reports and emergency instruction sheets of 119 ESCC from January to December 2016 were reviewed. For more accurate status analysis, the computerized data of the 1339 Emergency Medical Information Center from January to December 2011 were also reviewed. RESULTS: In 2016, the total usage of the 119 ESCC was 1,393,876 calls, which was 27.8% lower than the 1,930,977 calls in 2011. Of the 1,393,876 eligible calls, the most common call was hospital guidance (n=743,799, 53.4%), followed by first aid (n=397,620, 28.5%), disease consultation (n=150,128, 10.8%), medical oversight (n=81,174, 5.8%), and interhospital transfer (n=5,123, 0.4%). Regarding the user number per 10,000 persons, Daejeon was the greatest at 57.2, whereas Changwon was the lowest at 11.5. A total number of DA-CPR was 19,439. The time from the call to chest compression were 173±88.6 seconds in the subjects having previous cardiopulmonary resuscitation training and 184.0±88.2 in the subjects having no such training (P < 0.001). CONCLUSION: The ratio of first aid instructions, including DA-CPR, among total usage of the 119 ESCC increased but the overall usage of the 119 ESCC decreased. Therefore, further efforts will be needed to improve the quality and professionality of the information provided through the operation of 119 ESCC.

Survey of emergency medicine residency education programs and suggestion for improvement on the future emergency medicine residency education

OBJECTIVE: This study examined the educational programs for emergency residency in The Korean Society of Emergency Medicine. METHODS: A written survey of the workshop programs with representatives of the related organizations and affiliated organizations was conducted. During the 5-year period, the number of training courses and workshops attended by those who took the professional examination were analyzed. RESULTS: There were 23 workshops in progress. They proceed 2.85 times a year on average. The average number of participants was 22.8 with an average time required for the workshop of 5.6 hours, of which 78.7% is practice time. They received feedback from residency at all workshops, which was reflected in the process. During the 5-year period, the average number of participant training courses was 3.8, and the average number of workshop participants was 2.7. CONCLUSION: The education program for emergency residency is continuing through the affiliated organizations and related organizations as well as The Korean Society of Emergency Medicine. Encouraging opportunities for participation in various educational programs to supplement those that are not fully experienced will be helpful.

Association between Smoking and Delayed Neuropsychological Sequelae in Acute Carbon Monoxide Poisoning

PURPOSE: This study examined the association between smoking and delayed neuropsychological sequelae (DNS) in acute carbon monoxide (CO) poisoning. METHODS: Patients admitted to the medical center emergency department from March 2016 to March 2017 because of CO poisoning were examined retrospectively. The patients were divided into two groups: DNS and Non-DNS group. Multiple factors were analyzed to explain DNS, which was assessed by motor disturbances, cognitive impairment, dysphagia, Parkinson-like syndromes, epilepsy, and emotional lability in CO poisoning. RESULTS: A total of 120 patients were included. The factors related to DNS were smoking (pack-years) (p=0.002) and initial carbon monoxide-hemoglobin level (p=0.015). On the other hand, after multivariate logistic regression analysis, smoking (Odds ratio 1.07; 95% CI, 1.02-1.13; p=0.004) was the only factor associated with DNS. CONCLUSION: Smoking is a very reliable factor for predicting the occurrence of DNS. A history of smoking in patients who suffer from CO intoxication is important. If a patient smokes, treatment should be started actively and as soon as possible.

A Study on the Disaster Medical Response during the Mauna Ocean Resort Gymnasium Collapse

PURPOSE: To investigate and document a disaster medical response during the collapse of the Gyeongju Mauna Ocean Resort gymnasium, which occurred on February 17, 2014. METHODS: The official records of each institution were verified to select the study population. All the medical records and emergency medical service records were reviewed by an emergency physician. Personal or telephonic interviews were conducted without a separate questionnaire if the institutions or agencies crucial to disaster response did not have official records or if information from different institutions was inconsistent. RESULTS: One hundred fifty-five accident victims, who were treated at 12 hospitals mostly for minor wounds, were included in this study. The collapse killed 10 people. Although the news of the collapse was disseminated in 4 minutes, it took at lease 69 minutes for a dispatch of 4 disaster medical assistance teams to take action; 4.5% of patients were treated on-site, 56.7% were transferred to 2 nearest hospitals, and 42.6% were transferred to hospitals with poor preparation to handle disaster victims. CONCLUSION: In the collapse of the Gyeongju Mauna Ocean Resort gymnasium, the initial triage and distribution of patients were inefficient, with delayed arrival of medical assistance teams. These problems had also been noted in prior mass casualty incidents. Government agencies are implementing improvements, and this study could aid the implementation process.

Confirmation of the Relation between Femoral Artery and Vein for Central Venous Cannulation: A Prospective Investigation Using Ultrasound

PURPOSE: Femoral vein catheterization is often performed using a landmark technique, despite the recommended method of using ultrasound guidance. Although the landmark-based procedure is a well-known, widely adopted method to date, there are insufficient studies validating the effectiveness of this method. Hence, the purpose of this study was to confirm the relationship between femoral artery and vein using an ultrasound, as well as to validate the effectiveness of the femoral vein catheterization method using the landmark technique. METHODS: This was a prospective, repeated measurement study. Using an ultrasound with a 10 MHz transducer, the femoral vein cross-sectional areas on the right side were saved at a distance of 1, 2, 3, and 4 cm from the inguinal ligament with supine and hip abduction-external rotation positions. The width of the femoral vessels, center-to-center distance between the femoral artery and vein(horizontal distance between the center of the femoral artery and vein) and width of exposed femoral vein (not posterior to femoral artery) were measured. RESULTS: The width of the femoral vein, the center-to-center distance between the femoral artery and vein, as well as the width of the exposed femoral vein were significantly decreased as the distance from the inguinal ligament was increased, regardless of the posture change (p<0.001). However, at a distance of 1 cm from the inguinal ligament, only 5.4% of the femoral veins were exposed without disturbance of the femoral artery, and there were also a few cases in which the femoral veins were not exposed at all. CONCLUSION: It appears that an ultrasound-guided femoral vein catheterization is recommended over the conventional landmark technique.

A study on the disaster medical response during the Mauna Ocean Resort gymnasium collapse

OBJECTIVE: To investigate and document the disaster medical response during the Gyeongju Mauna Ocean Resort gymnasium collapse on February 17, 2014. METHODS: Official records of each institution were verified to select the study population. All the medical records and emergency medical service run sheets were reviewed by an emergency physician. Personal or telephonic interviews were conducted, without a separate questionnaire, if the institutions or agencies crucial to disaster response did not have official records or if information from different institutions was inconsistent. RESULTS: One hundred fifty-five accident victims treated at 12 hospitals, mostly for minor wounds, were included in this study. The collapse killed 10 people. Although the news of collapse was disseminated in 4 minutes, dispatch of 4 disaster medical assistance teams took at least 69 minutes to take the decision of dispatch. Four point five percent were treated at the accident site, 56.7% were transferred to 2 hospitals that were nearest to the collapse site, and 42.6% were transferred to hospitals that were poorly prepared to handle disaster victims. CONCLUSION: In the Gyeongju Mauna Ocean Resort gymnasium collapse, the initial triage and distribution of patients was inefficient and medical assistance arrived late. These problems had also been noted in prior mass casualty incidents.

Epidemiology and Outcomes in Out-of-hospital Cardiac Arrest: A Report from the NEDIS-Based Cardiac Arrest Registry in Korea

Sudden cardiac death (SCD) is a significant issue affecting national health policies. The National Emergency Department Information System for Cardiac Arrest (NEDIS-CA) consortium managed a prospective registry of out-of-hospital cardiac arrest (OHCA) at the emergency department (ED) level. We analyzed the NEDIS-CA data from 29 participating hospitals from January 2008 to July 2009. The primary outcomes were incidence of OHCA and final survival outcomes at discharge. Factors influencing survival outcomes were assessed as secondary outcomes. The implementation of advanced emergency management (drugs, endotracheal intubation) and post-cardiac arrest care (therapeutic hypothermia, coronary intervention) was also investigated. A total of 4,156 resuscitation-attempted OHCAs were included, of which 401 (9.6%) patients survived to discharge and 79 (1.9%) were discharged with good neurologic outcomes. During the study period, there were 1,662,470 ED visits in participant hospitals; therefore, the estimated number of resuscitation-attempted CAs was 1 per 400 ED visits (0.25%). Factors improving survival outcomes included younger age, witnessed collapse, onset in a public place, a shockable rhythm in the pre-hospital setting, and applied advanced resuscitation care. We found that active advanced multidisciplinary resuscitation efforts influenced improvement in the survival rate. Resuscitation by public witnesses improved the short-term outcomes (return of spontaneous circulation, survival admission) but did not increase the survival to discharge rate. Strategies are required to reinforce the chain of survival and high-quality cardiopulmonary resuscitation in Korea.

Prehospital Cardiopulmonary Resuscitation by 119 Emergency Medical Technician (EMT) for Increasing the Rate of Return of Spontaneous Circulation; National-Wide 119 EMT Survey

PURPOSE: The out-of-hospital cardiac arrest (OHCA) survival rate of patients in Korea is lower than the global average and it might be caused by an extremely low rate of return of spontaneous circulation in the prehospital field. The authors identified obstacles that disturb on-scene performance of cardiopulmonary resuscitation (CPR) for a certain period from 119 emergency medical technicians (EMTs) through a nation-wide paper survey. METHODS: A total of 1273 first grade EMTs and nurses were surveyed. CPR time performed on the scene (without transfer), CPR experiences, self-assessment of CPR skill performance, and both obstacles to performance of CPR on the scene and solutions to overcoming them for continuous on-scene CPR were investigated using a 28-item questionnaire. RESULTS: The average for work experience and the number of CPR experiences of subjects was 6.8+/-4.5 years and 1.9+/-1.7 times/month, respectively. Survey results for CPR times on the scene showed an average of 4.2+/-2.4 minutes, approximately two periods of CPR (30:2x5 cycles). Obstacles to CPR on the scene were investigated as complaints of family members in 791(62.1%) and fatigue lowering CPR quality due to lack of human resources in 536(41.0%); 627(49.3%) of the subjects answered that they had received complaints due to a long stay on the scene. CONCLUSION: In order to increase the survival rate of OHCA patients, CPR on the scene is needed during a certain period in order to achieve a return of spontaneous circulation. Education, amelioration of guidelines, and support for the EMT administrative system are also needed.

Education, amelioration of guidelines, and support for the EMT administrative system are also needed.

Recent 10-Year Experience of One Regional Emergency Center and Recommendation for Hyperbaric Oxygen Therapy (HBOT)

PURPOSE: The aim of this study is to investigate current status, indications, and complications of hyperbaric oxygen therapy. METHODS: A retrospective investigation of patients who underwent hyperbaric oxygen therapy at a university medical center from September 2004 to August 2013 was conducted based on patients' medical records and results of an email survey for 99 emergency centers. RESULTS: During the study period, a total of 233 patients underwent hyperbaric oxygen therapy. Indications for hyperbaric oxygen treatment of illness or injury were as follows: 1) 151 cases of acute carbon monoxide poisoning(65.4%), 2) flap wound management, including 42 cases(18.2%), 3) skin care transplanted, including 23 cases(10.4%), 4) Burger's disease, including 5 five cases(2.1%), respectively. Total application time* frequency was 1,088 and total time was 1,239 hours. Among 233 patients who underwent hyperbaric oxygen therapy, 32 patients(13.7%) had complications: 1) otalgia in 21 cases(9.0%), 2) mastoiditis? in six cases(2.6%), 3) hemotympanum in five cases(2.1%), respectively. There were only 8 emergency centers that currently had an operational hyperbaric oxygen chamber in 77 emergency centers(10.4%). CONCLUSION: Indications identified through this study showed difference from current indications worldwide. It seems necessary that physicians' perception regarding application of hyperbaric oxygen therapy for more indications be changed and improved. A hyperbaric chamber capable of providing respiratory assistance and intensive care is also needed. A good network for sharing treatment experiences and a specialized team for administration of hyperbaric oxygen therapy is also required.

Injuries Associated with the 580 km University Student Grand Voluntary Road March: Focus on Foot Injuries

College student volunteers (n = 142) completed a 580 km road march for 21 consecutive days. Each volunteer carried a backpack that weighed 14.1 +/- 1.4 kg on the average. We investigated the incidence and location of blisters associated with the road march using a foot map along with other injuries. Overall, 95.1% of the subjects (135 of 142) sustained one or more injuries. All injured subjects had foot blisters, and 18% had other foot injuries. The most common locations of blister development were the right 5th toe (61%) and the left 5th toe (57%). The little toes seem to have been subjected to the greatest friction and shearing forces. March-related injuries, excluding foot injuries, were ankle pain (12.7%), knee pain (12.7%) and Achilles tendon pain (7.7%). Six subjects (4.2%) needed extra medical treatment for more than 2 weeks prior to returning to their daily lives after completion of the march due to associated injuries. The present study observed a very high incidence rate of injuries (95.1%) associated with the 580 km university students grand road march. These injuries posed an obstacle against completion of the road march and against returning to daily life. Active preventive interventions such as physical therapy and customized reinforced shoes and education program are recommended for reducing incidence rate and severity of injuries.

Cardiovascular Manifestations and Clinical Course after Acute Carbon Monoxide Poisoning

PURPOSE: The aim of this study was to evaluate the cardiovascular manifestations and clinical course in patients with acute carbon monoxide poisoning. METHODS: A retrospective study was conducted over a 36 month period on consecutive patients who visited an emergency medical center and were diagnosed with acute carbon monoxide poisoning. A standardized data extraction protocol was performed on the selected patients. RESULTS: A total of 293 patients were selected during the study period. Cardiac manifestations were observed in 35.2% (n=103) of the patients: hypotension in 11 patients (3.8%), ECG abnormalities in 44 patients (15.0%) and cardiac enzyme abnormalities in 103 patients (35.2%). Echocardiography was performed on 56 patients with cardiac toxicity: 12 patients had abnormal results (5 patients with global hypokinesia and 7 patients with regional wall akinesia). Five patients died within 3 hours after ED admission, and the remaining patientswere discharged alive. At 3 months after discharge, none of these patients had died.The SOFA scores in the severe cardiac toxicity group and non-severe cardiac toxicity group at the time of arrival were 2.53+/-2.29 and 2.19+/-2.12, respectively (p=0.860). CONCLUSION: Cardiovascular manifestations occurafter acute CO poisoning at arateof 35.2%. Even those with severe cardiovascular toxicity recovered well within 10 days after admission. Therefore, the importance of cardiac toxicity after acute CO poisoning is not significant initself in the clinical course, and the short-term prognosis of cardiac toxicityis unlikely to be unfavorable in acute CO poisoning.

Comparison of Manual Versus Mechanical Chest Compression During Simulative out of Hospital Cardiac Arrest

PURPOSE: The quality of cardiopulmonary resuscitation (CPR) has been identified as an important factor for improving survival rate. This prospective study was conducted for comparison of manual chest compression and mechanical chest compression during simulative out of hospital cardiac arrest. And evaluation of quality of manual compression was performed on-scene and during ambulance transportation. METHODS: A total of 24 emergency medical technicians (EMTs) participated in our study. During a period of one month, they were educated by E-learning on the importance of decreasing hands off time during CPR and anything else about CPR. We instituted the scenario of out of hospital cardiac arrest. They performed CPR twice in each same situation: they performed manual chest compression the first time. And, the second time, they used the mechanical chest compression device (X-CPR(TM)). We evaluated the performance by camcorder monitoring and Q-CPR(TM) for measurement of manual compression depth and flow time. RESULTS: A total of 48 cases were performed in this study. Twenty four cases were included in the manual CPR group (H-Group) and 24 cases were included in the mechanical group (M-group). CPR of the H group vs. the M group was performed for a mean 19.71+/-2.97 min, 21.95+/-4.16 min on scene, and in a moving ambulance. The average compression rate was 122+/-14.80 min-1 vs 104.38+/-6.40 min-1 (p<0.001), and the compression depth was 44.25+/-8.50 mm vs 42.37+/-4.28 mm (p=0.34), respectively. No statistical difference was observed in the flow time ratio between manual and mechanical chest compression (67.04+/-11.12 vs 64.13+/-6.61, p=0.28). However, the quality of compression of the H-group, the ratio of insufficient compression, and the ratio of insufficient release during transport were higher than those on-scene (p=0.02, p=0.01). CONCLUSION: In comparison of chest compression rates between the two groups, the M-group showed a higher rate of chest compression. However, no significant difference in chest compression depth and flow time ratio was observed between the H- and M-groups. When performing manual chest compression during transport, EMTs should be careful of adequate chest compression and release.

Comparative Study of Prehospital Airway Devices Tested Using a Manikin Model: A Comparison of the Laryngeal Mask Airway Classic (LMA Classict(TM)), Cobra Perilaryngeal Airway (Cobra PLA(TM)) and the King Laryngeal Tube (King LT(TM))

PURPOSE: Prehospital airway management is crucial to emergency healthcare providers, especially for emergency medical technicians (EMTs). In spite of its clinical importance, adequate airway management cannot be guaranteed only with the use of endotracheal intubation. Many supraglottic airway devices have been introduced as substitutes for endotracheal intubation. We compared 3 such devices - LMA Classic(TM), Cobra PLA(TM) and King LT(TM) - using a manikin and recorded performance skill and preference. METHODS: Thirty EMTs participated in the airway management educational program and were enrolled in this study which was held in the Gyeong-Gi Fire Academy. We surveyed the participants general characteristics and experience by e-mail prior to this laboratory study of their skills. The airway management program consisted of a 10 minute lecture followed by 20 minutes of skill training. We observed the success rate, preference among the 3 devices, and the total procedure time of airway device insertion in different rooms. RESULTS: The LMA Classic(TM), Cobra PLA(TM) and King LT(TM) groups succeeded 90%, 76.7%, and 80%, respectively at the first trial. There was no statistically significant difference among the groups (p=0.372). To achieve adequate airway management, the groups spent 28.6+/-7.2, 24.7+/-4.9, and 26.9+/-7.0 seconds, respectively, again with no significant differences (p=0.108). A preference survey performed after the test showed the highest preference for King LT(TM), 57%. CONCLUSION: Three prehospital supraglottic airway devices showed no differences in success rate or procedure time. Despite this result, King LT(TM) was the most preferred.

Current State and Problem of the Transfer of Severely Injured Patients in One Regional Emergency Medical Center

PURPOSE: Trauma is one of the leading causes of death, especially among young people. Life-threatening conditions are very common in multiple-traumatized patients due to concurrent multi-organ injuries. Treating such severely injured patients is time critical. However, in Korea, the transfer of severely injured patients is not uncommon due to the lack of a mature trauma care system. In developed countries, the preventable trauma death rate is very low, but the rate is still very high in Korea. This study's objective was to demonstrate the current serious state in which severely injured patients have to be transferred from a Regional Emergency Medical Center even though it actually serves as a trauma center. METHODS: Ajou University Medical Center is a tertiary hospital that serves as a trauma center in Gyeonggi-do. The medical records at Ajou University Medical Center for a 1-year period from January 1, 2008, to December 31, 2008, were retrospectively reviewed. A severely injured patient was defined as a patient who showed more than 15 point on the ISS (injury severity score) scale. We investigated the clinical characteristics of such patients and the causes of transfer. RESULTS: Out of 81,718 patients who visited the Regional Emergency Medical Center, 19,731 (24.1%) were injured patients. Among them, 108 severely-injured patients were transferred from one Regional Emergency Medical Center to other hospitals. The male-to-female ratio was about 3.5:1, and the mean ISS was 23.08. The most common mechanism of injury was traffic accidents (41.7%). A major cause of transfer was the shortage of intensive care units (44.4%); another was for emergent operation (27.8%). Most of the hospitals that received the severely-injured patients were secondary hospitals (86.1%). CONCLUSION: Although the Regional Emergency Medical Center played a role as a trauma center, actually, severely-injured patients had to be transferred to other hospitals for several reasons. Most reasons were related with the deficiencies in the trauma care system. If a mature trauma care system is well-organized, the numbers of transfer of severely injured patients will be reduced significantly.

Bickerstaff's Brainstem Encephalitis Accompanied by Encephalopathy Associated with Autoimmune Thyroid Disease (EAATD): Case Report and Review

Bickerstaff's brainstem encephalitis (BBE) is characterized by a consciousness disorder, ophthalmoplegia and ataxia. Some patients with BBE show hyperreflexia, pyramidal signs and sensory disturbance. The pathophysiology of BBE is not proven; it is presumed that an autoimmune response has a key role. Encephalopathy-associated with autoimmune thyroid disease (EAATD) is another encephalopathy presumed to be related to autoimmune responses. Patients with EAATD show cognitive dysfunction, seizures, and other neurologic deficits, with elevated antithyroid antibody and good responsiveness to steroid therapy. Here we described a case of a 26-year-old woman who presented with the characterstics of BBE and EAATD.
