Purpose Triage tools play a vital role in classifying the severity of children in emergency departments (EDs). We investigated the association between the Korean Triage and Acuity Scale (KTAS) and severity of dyspnea in the ED. Methods We conducted a retrospective study of children aged 3-14 years with dyspnea who visited the ED from January 2015 through December 2021. They were divided into severe (KTAS level 1-3) and non-severe (KTAS level 4-5) groups. Between the groups, we compared the clinical characteristics, including age, sex, associated symptoms, vital signs, route of visit, treatment at ED, and outcomes. Results Among a total of 468 children with dyspnea, 267 and 201 were assigned to the severe and non-severe groups, respectively. The severe group had higher frequencies of fever (21.7% vs. 13.9%; P = 0.031), cough (53.2% vs. 43.3%; P = 0.034), systemic steroids (42.3% vs. 25.9%; P < 0.001), intravenous fluids (47.6% vs. 25.4%; P < 0.001), oxygen therapy (16.5% vs. 6.5%; P = 0.001), inotropics (4.1% vs. 1.0%; P = 0.042), and hospitalization (24.7% vs. 11.9%; P = 0.002). The severe group also showed a higher mean heart rate, respiratory rate, and temperature, and lower mean oxygen saturation (all Ps < 0.001). Among these findings, fever, heart rate, respiratory rate, temperature, intravenous fluids, oxygen therapy, inotropics, and hospitalization remained significantly different between the groups after defining the severe group as a KTAS level 1-2. Conclusion This study shows the association between KTAS and severity of dyspnea in the ED. Therefore, KTAS may reflect not only the initial clinical conditions but also emergency measures and outcomes in children with dyspnea who visit EDs.

Purpose We aimed to identify the factors associated with the repeated febrile seizures (RFS), defined as recurrent seizures during the same febrile illness. Methods We reviewed the medical records of children with febrile seizure who visited 4 academic emergency departments from October 2016 through September 2018. Differences were identified in variables regarding clinical and laboratory characteristics between the children with and without RFS. The RFS was the primary outcome. Logistic regression was conducted to identify factors associated with the occurrence of RFS. Results Among 1,551 children, 922 were included in the study, of whom, 198 (21.5%) underwent RFS. Of the children with RFS, 188 (94.9%) underwent the recurrences within the initial 24 hours. Logistic regression showed focal seizure (adjusted odds ratio, 6.67; 95% confidence interval, 2.37-18.82), venous pH < 7.31 (5.89; 3.13-11.08), and postictal drowsiness > 30 minutes (1.90; 1.30-2.78) as the factors for RFS. Conclusion In children with febrile seizure, focal seizure, acidosis, and prolonged postictal state may be independent risk factors for RFS. These findings may be informed to healthcare professionals and parents caring for children with febrile seizure.

Purpose In infants and young children, acute bronchiolitis is a leading cause of hospitalization via emergency departments (EDs). We aimed to investigate factors associated with hospitalization via ED in children with acute bronchiolitis. Methods We reviewed medical records of children aged 36 months or younger with acute bronchiolitis who visited the ED from January to December 2017. The following clinical data were collected and analyzed: age, sex, premature birth history, symptoms, fever duration, presence of respiratory distress and radiographic lesion, and inflammatory markers. Results Of 780 children enrolled, 463 (59.4%) were hospitalized via the ED. The factor associated with the hospitalization were age ≤ 12 months (odd ratio [OR], 45.34; confidence interval [CI], 17.50-117.44), fever lasting ≥ 3 days (OR, 13.66; 95% CI, 6.46-28.87), respiratory rate ≥ 24 breaths per minute (OR, 6.88; 95% CI, 4.21-11.26), radiographic lesion (OR, 5.70; 95% CI 2.62-12.40), and chest retraction (OR, 2.45; 95% CI, 1.11-5.41). Conclusion In children with acute bronchiolitis who visit EDs, those having younger age, longer fever duration, respiratory distress or radiographic lesion may need hospitalization.

Purpose The Korean Triage and Acuity Scale (KTAS) is a triage tool for patients in the emergency department (ED). We aimed to investigate the association between the KTAS level and hospitalization of children with abdominal pain, a common chief complaint in the ED. Methods This study retrospectively reviewed medical records of children aged 3 to 14 years who visited the ED with abdominal pain as a chief complaint. KTAS level (1-3 vs. 4-5), age, gender, presence of associated symptoms (vomiting, diarrhea, hematochezia, and fever), and disposition (rapid discharge, discharge after intravenous hydration, and hospitalization) were collected and compared between the children with KTAS 1-3 and 4-5. Results Of 1,050 children enrolled, 618 (58.9%) were classified as KTAS 1-3, and 36 (3.4%) were hospitalized. Vomiting was the most common associated symptom in both groups (63.6%), and 41.5% underwent discharge after intravenous hydration. The children with KTAS 1-3 were more frequently hospitalized (5.0% vs. 1.2%, P < 0.001). Conclusion The KTAS may be reliable to predict the hospitalization of children with abdominal pain in the ED with additional consideration of the associated symptoms.

Background: Many acute poisoned patients have co-ingested alcohol in the emergency department (ED). This study aimed to estimate the blood alcohol concentration (BAC) of acute poisoned patients who visited an ED by age and gender distribution and to determine whether it is possible to obtain self-reports of alcohol ingestion among poisoned patients. Method: A retrospective medical chart review was conducted for all patients who visited the ED with acute poisoning between January 2004 and February 2008. Data regarding the patient's age, gender, BAC, self-reported alcohol ingestion, poison ingested, time elapsed since poison exposure, presence of suicide attempts, and self-reported alcohol ingestion were collected. Patients were classified into two groups based on serum alcohol levels (=10 mg/dl, >10 mg/dl). Results: Of the 255 subjects, 88 subjects (34.5%) were included in the non-alcohol group and 167 subjects (65.5%) were included in the alcohol group. 227 subjects (89.0%) showed suicide intention. Using the 201 subjects who completed the self-report of alcohol ingestion, self-report resulted in 96.6% sensitivity and 86.7% specificity for the assessment of alcohol ingestion. The positive and negative predictive values for self-report were 91.2% and 94.7%, respectively. The median (interquartile range) BAC of the 97 males in the sample was 85.0 (10.0-173.5) mg/dl, and that of the 158 females was 32.0 (4.0-137.5) mg/dl (p = 0.010). The distribution of age in the groups was significantly different between the alcohol and non-alcohol groups (p = 0.035), and there was a significant difference in the mean BAC with respect to age for males (p = 0.003). Conclusion: This study showed that over two-thirds of patients presenting with acute poisoning had a BAC > 10 mg/dl. Most of patients visited by suicide attempt. Males had a higher BAC than did females. Self-reported alcohol ingestion in acute poisoned patients showed high sensitivity and specificity. [ABSTRACT FROM AUTHOR]

Objective Procedural sedation and analgesia (PSA) in children has become a standard tool in emergency settings, but no national PSA guidelines have been developed for the emergency department (ED) in Korea. Therefore, we investigated the practice of PSA and the level of adherence to institutional PSA guidelines in EDs of teaching hospitals. Methods This study was a cross-sectional, web-based survey. The study subjects were the faculty of EDs from 96 teaching hospitals. The questionnaire was posted on an internet site, and the participants were requested that the questionnaire be answered by email and telephone in May 2009. Results The questionnaires were completed by 67.7% of the participants. Only 20% of EDs had institutional PSA guidelines, 21.5% of those had discharge criteria and 13.8% of EDs had a discharge instruction form. Residents were administered PSA at 76.9% of EDs. The airway rescue equipment was near the area where PSA was performed in 76.9% of EDs. The most commonly used medication for both diagnostic imaging and painful procedure was oral chloral hydrate (87.7%, 61.5%). In 64.6% of EDs, patients were monitored. In only 21 cases, EDs (50.0%) monitored the patients to recovery after PSA or discharge. Conclusions Current PSA for paediatric patients have not been appropriately applied in Korea. Unified PSA guidelines were rare in the hospitals surveyed, and many patients were not monitored over an appropriate duration, nor did they receive adequate medications for sedation by the best trained personnel. Therefore, the national PSA guidelines must be developed and implemented as early as possible. [ABSTRACT FROM AUTHOR]

Hypothermia increases clotting time, which is known as hypothermic coagulopathy. However, prothrombin time and activated partial thromboplastin time prolongation associated with therapeutic hypothermia is usually mild and thus, hypothermic coagulopathy is not considered to cause clinically significant bleeding. On the other hand, PT and aPTT do not seem to reflect the severity of hypothermic coagulopathy. Serious bleeding complications of therapeutic hypothermia has not been reported previously. Herein, we introduce a case of spontaneous brain stem hemorrhage as a complication of therapeutic hypothermia-induced coagulopathy. [ABSTRACT FROM AUTHOR]

Benzodiazepines are widely used for many diseases, and benzodiazepine overdose is globally increasing in proportion to its prescriptions. Although most benzodiazepine overdoses are known to be safe and nonfatal without coingestions, morbidity or mortality after benzodiazepine overdose is closely related with the duration of unconsciousness or depth of compromised airway. Proper use of flumazenil, a potent antidote of benzodiazepine, seems to accelerate the recovery from the toxicity after benzodiazepine overdose. However, as the case we present demonstrates, careful attention and repetitive evaluations before and after use of flumazenil may be needed in benzodiazepine overdose because resedation occurs in approximately 30% of total flumazenil-treated cases, which suggests that the risk of aspiration or incidental death after administrating flumazenil might be significant without careful monitoring.

Purpose To compare the efficacy of inflammatory markers, the Laboratory-score, and a new laboratory combined model for predicting serious bacterial infection (SBI) in young febrile children. Methods The presence of SBI was reviewed in previously healthy children aged 3 years or younger with fever (> 38℃) who visited the emergency department from 2017 through 2018. Areas under the curves (AUCs) of the receiver operating characteristic curve for SBI were compared with individual inflammatory markers (white blood cells [WBC] count, erythrocyte sedimentation rate [ESR], C-reactive protein [CRP], procalcitonin [PCT], and urine WBC count), the Laboratory-score, and a laboratory combined model. The latter model was developed using logistic regression analysis including ESR, CRP, and PCT. Results Of the 203 enrolled children, SBI was diagnosed in 58 (28.6%). For SBI prediction, the Laboratory-score showed 51.7% sensitivity (95% confidence interval [CI], 38.2%-65.0%) and 83.5% specificity (95% CI, 76.4%-89.1%). The AUC of the Laboratory-score (0.76) was significantly superior to the values of all individual inflammatory markers (WBC, 0.59 [P = 0.032]; ESR, 0.69; and CRP, 0.74 [P < 0.001]) except that of PCT (0.77, [P < 0.001]). The AUC of the laboratory combined model (0.80) was superior to that of the Laboratory-score (0.76) (P < 0.001). Conclusion In this study, the new laboratory combined model showed good predictability for SBI. This finding suggests the usefulness of combining ESR, CRP, and PCT in predicting SBI.
