Splenic artery aneurysm is the third most common type of intra-abdominal aneurysm, with a prevalence rate of 0.01% to 10.4% in the general population. Splenic artery aneurysm is usually asymptomatic and is typically detected by chance and does not require surgical management; however, if rupture occurs, although rare, the patient's situation can become critical. We report our experience with a man who presented with left flank and left shoulder pain. His symptoms were caused by multiple hematomas confined to the spleen, but 2 days after admission, he developed delayed hemoperitoneum and required surgical management. We believe that his condition was due to delayed intraperitoneal bleeding called the double-rupture phenomenon; emergency physicians must consider this phenomenon when taking care of splenic artery aneurysm patients.

Dae Won LEE ; Yoon Hee CHOI

Clinical and Experimental Emergency Medicine.2017;4(2):109-112. doi:10.15441/ceem.16.121

Spinal cord infarction is a rare condition and is easily misdiagnosed owing to its initial non-specific manifestation. We report a case of a 77–year-old man who presented with chest pain and upper back pain initially, and was misdiagnosed with a myocardial infarction. Four hours after admission, he complained of numbness in his entire left leg below the knee, with rapid deterioration of neurological symptoms. After 9 hours, loss of sensation progressed up to the T4 dermatome, strength of both lower extremities deteriorated to grade 0, and decrease in anal tone and deep tendon reflex was observed. Initial magnetic resonance imaging findings were normal; however, a signal change occurred 3 days after symptom onset. When patients present with acute chest pain and neurologic symptoms, the possibility of ischemic cardiac disease as well as any neurological manifestations must be investigated. Emergency physicians must remember the value of serial physical examinations.

Clinical and Experimental Emergency Medicine.2017;4(2):102-108. doi:10.15441/ceem.14.024

OBJECTIVE: The aim of this study was to elucidate the epidemiology of pediatric patients transported by the National 119 Rescue Services in Korea. METHODS: We enrolled all pediatric patients (<16 years old) who used the National 119 Rescue Services in Korea between January 2006 and December 2008, and analyzed the 119 ambulance patient care record databases. RESULTS: The total number of the cases was 238,644 for 3 years. The median age was 6 years old and 59.0% were male, and the 2- to 5-year-old group was the largest (31.0%). The peak transport times were in the afternoon (from 12:00 p.m. to 17:59 p.m., 36.3%), on Saturday and Sunday (15.9% and 15.7%), and in summer (June to August, 27.3%). The ratio of disease versus injury as the cause of the transports was 42.3% vs. 57.7%. Among the 16 metropolitan cities and provinces, Gyeonggi (25.7%), Seoul (17.6%), and Incheon (7.0%) account for almost half of the all transported children. Regarding the annual transport rates per 100,000 children standardized by age, and gender to the Korean child population, Jeju was the largest (1,650.2) followed by Gangwon (1,201.3), and Jeonnam (1,178.1). CONCLUSION: This report presents comprehensive epidemiologic data of pediatric patients transported by 119 rescue services in Korea.

OBJECTIVE: Outbreaks of transmissible respiratory infection are suspected to have significant effects on the health of pediatric and geriatric patients. The objective was to assess the impact of the Middle East respiratory syndrome (MERS) outbreak on the use of emergency resources. METHODS: An ecologic analysis of emergency department (ED) records between September and December 2015, was performed. Data was obtained from the National Emergency Department Information System database for Korea. All demographic and diagnostic data from patients presenting with febrile symptoms as a main complaint were collected. The data were compared to the equivalent period in the three years preceding the MERS outbreak in Korea. RESULTS: Following the MERS outbreak, there was an increase in overall ED visits by febrile patients and the proportion of visits by febrile patients, relative to total ED attendances. This effect was more prominent in the children under five years. The duration of the chief complaint before ED arrival and the length of ED stay were significantly increased among younger pediatric patients. Decreased body temperature on arrival was observed in younger pediatric patients. CONCLUSION: MERS outbreak appears to have had a significant effects on ED use by febrile patients. The use of emergency care services by pediatric patients makes them more vulnerable to an outbreak of a transmissable disease. An effective strategy to control emergency center visits by non-urgent febrile patients and provide proper medical services is urgently needed.

Clinical and Experimental Emergency Medicine.2017;4(2):88-93. doi:10.15441/ceem.16.175

OBJECTIVE: Cardiopulmonary resuscitation (CPR) training can improve performance during simulated cardiac arrest; however, retention of skills after training remains uncertain. Recently, hands-only CPR has been shown to be as effective as conventional CPR. The purpose of this study is to compare the retention rate of CPR skills in laypersons after hands-only or conventional CPR training. METHODS: Participants were randomly assigned to 1 of 2 CPR training methods: 80 minutes of hands-only CPR training or 180 minutes of conventional CPR training. Each participant's CPR skills were evaluated at the end of training and 3 months thereafter using the Resusci Anne manikin with a skill-reporting software. RESULTS: In total, 252 participants completed training; there were 125 in the hands-only CPR group and 127 in the conventional CPR group. After 3 months, 118 participants were randomly selected to complete a post-training test. The hands-only CPR group showed a significant decrease in average compression rate (P=0.015), average compression depth (P=0.031), and proportion of adequate compression depth (P=0.011). In contrast, there was no difference in the skills of the conventional CPR group after 3 months. CONCLUSION: Conventional CPR training appears to be more effective for the retention of chest compression skills than hands-only CPR training; however, the retention of artificial ventilation skills after conventional CPR training is poor.

Clinical and Experimental Emergency Medicine.2017;4(2):80-87. doi:10.15441/ceem.16.160

OBJECTIVE: Bystander cardiopulmonary resuscitation (CPR) is an important factor associated with improved survival rates and neurologic prognoses in cases of out-of-hospital cardiac arrest. We assessed how factors related to CPR education including timing of education, period from the most recent education session, and content, affected CPR willingness. METHODS: In February 2012, trained interviewers conducted an interview survey of 1,000 Daegu citizens through an organized questionnaire. The subjects were aged ≥19 years and were selected by quota sampling. Their social and demographic characteristics, as well as CPR and factors related to CPR education, were investigated. Chi-square tests and multivariate logistic regression analyses were used to evaluate how education-related factors affected the willingness to perform CPR. RESULTS: Of total 1,000 cases, 48.0% were male. The multivariate analyses revealed several factors significantly associated with CPR willingness: didactic plus practice group (adjusted odds ratio [AOR], 3.38; 95% confidence interval [CI], 2.3 to 5.0), group with more than four CPR education session (AOR, 7.68; 95% CI, 3.21 to 18.35), interval of less than 6 months from the last CPR education (AOR, 4.47; 95% CI 1.29 to 15.52), and education with automated external defibrillator (AOR, 5.98; 95% CI 2.30 to 15.53). CONCLUSION: The following were associated with increased willingness to perform CPR: practice sessions and automated electrical defibrillator training in public CPR education, more frequent CPR training, and shorter time period from the most recent CPR education sessions.

Clinical and Experimental Emergency Medicine.2017;4(2):73-79. doi:10.15441/ceem.16.194

OBJECTIVE: Disturbances in potassium (K) levels are relatively common and may be associated with significant morbidity and mortality; however, treatments vary. Our purpose was to determine the incidence, treatments, and outcomes associated with hyperkalemia and hypokalemia in emergency department (ED) patients. METHODS: We performed a structured, retrospective review of electronic medical records of consecutive adult ED patients with K measured while in the ED. Demographic, clinical, and laboratory data as well as treatments, disposition, and in-hospital complications were collected. Univariate and multivariate analyses, presented as adjusted odds ratios, were used to compare outcomes by K levels. RESULTS: Of 100,260 visits in 2014, an ED K level was ordered in 48,827 (49%). A total of 1,738 patients (3.6%) were excluded because of sample hemolysis. The K was low (<3.5 mEq/L) in 5.5%, normal (3.5 to 5.0 mEq/L) in 90.9%, and elevated (>5.0 mEq/L) in 3.6% of patients. Patients with hyperkalemia were older (64 vs. 49 years, P<0.001) and more likely male (58% vs. 40%, P<0.001). Treatment for hyperkalemia varied greatly. After adjusting for confounders, both hyperkalemia and hypokalemia were associated with inpatient hospitalization and death. At least one medication was used to manage hyperkalemia in 11.5% of patients with a K of 5.1 to 5.4 mEq/L, 36.4% of those with a K 5.5 to 6 mEq/L and 77.0% of the cohort with K >6 mEq/L. CONCLUSION: Hyperkalemia or hypokalemia occur in 1 of 11 ED patients and are associated with inpatient admission and mortality. Treatment of hyperkalemia varies greatly suggesting the need for evidence-based treatment guidelines.

OBJECTIVE: Acute myocardial infarction is a major cause of out-of-hospital cardiac arrest (OHCA). Coronary angiography (CAG) enables diagnostic confirmation of coronary artery disease and subsequent revascularization, which might improve the prognosis of OHCA survivors. Non-randomized data has shown a favorable impact of CAG on prognosis for this population. However, the optimal timing of CAG has been debated. METHODS: The clinical outcomes of 607 OHCA patients registered in CAPTURES (Cardiac Arrest Pursuit Trial with Unique Registration and Epidemiologic Surveillance), a nationwide multicenter registry performed in 27 hospitals, were analyzed. Early CAG was defined as CAG performed within 24 hours of emergency department admission. The primary outcome was survival to discharge, with neurologically favorable status defined by cerebral performance category scores ≤2. RESULTS: Compared to patients without CAG (n=469), patients who underwent early CAG (n=138) were younger, more likely to be male, and more likely to have received bystander cardiopulmonary resuscitation, pre-hospital defibrillation, and revascularization (P<0.01 for all). Analysis of 115 propensity score-matched pairs showed that early CAG is associated with a 2.3-fold increase in survival to discharge with neurologically favorable status (P<0.001, all). Survival to discharge increased consistently according to the time interval between emergency department visit and CAG (P<0.05). CONCLUSION: Early CAG of OHCA patients was associated with better survival and favorable neurologic outcomes at discharge. However, there was no clear time threshold for CAG that predicted survival to discharge.
