Shortage of doctors in emergency departments (EDs) is a root issue in maintaining ED-based residency programs. This study describes the efficiency of emergency practice according to board certification; 3 board-certified physicians versus a pediatric resident. Of 342 children, we found no differences as per the board certification in the ED length of stay, acuity, and return visits with more frequent hospitalization by the board-certified physicians. This result suggests that with a proper residency program, both board-certified physicians and residents can make a decision on hospitalization.

Abdominal compartment syndrome (ACS) involves adverse physiologic consequences arising from the increased intraabdominal pressure, leading to high mortality. However, this syndrome has been scarcely reported in pediatric emergency settings. We describe a 10-year-old boy with ACS presenting with painful abdominal distension, oliguria, and dyspnea. Despite the absence of known congenital anomalies, he had undergone frequent episodes of constipation since 5 years of age, and had not defecated for recent 2 months. With computed tomography scans showing the entire colorectal distension, his manifestations were considered to have stemmed from congenital aganglionic megacolon, which had gone undetected. This case underlines the needs for considering ACS and consequent surgical decompression in a child with severe abdominal distension.

Purpose: As coronavirus disease 2019 pandemic has been prolonged, it became crucial to analyze the long-term impact of the pandemic on emergency department (ED) utilization for efficient use of emergency medicine resources. Methods: We reviewed the data of children (≤ 18 years) who visited the ED in Daejeon, Korea, from February 2019 through January 2021. This period was dichotomized by February 2020 into the reference and pandemic periods. The latter period was further divided into the early (February-August 2020) and late pandemic periods. Between the reference and pandemic periods, and between the early and late pandemic periods, we respectively compared proportions of children in all patients (including adults), age groups, high acuity (the Korean Triage and Acuity Scale 1-2), diagnostic codes, visits via ambulances, ED length of stay, and ED disposition. Results: Compared to the reference and early pandemic periods, the pandemic and late pandemic periods respectively showed changes as follows: proportion of children in all patients (from 29.8% to 19.0% and from 19.8% to 18.1%; all Ps < 0.001), children younger than 5 years (from 56.7% to 49.9% and from 52.1% to 47.4%; all Ps < 0.001), high acuity (from 12.0% to 7.8% [P < 0.001] and from 8.8% to 6.7% [P = 0.004]), “Injury, poisoning and certain other consequences of external causes (S00-T98; from 30.0% to 49.0% and from 48.3% to 49.8%),” and “Diseases of the respiratory system (J00-J99; from 29.6% to 10.3% and from 12.8% to 7.5%).” Increases in the visits via ambulances, ED length of stay, children undergoing intensive care unit hospitalization or death were noted only in comparison between the reference and pandemic periods. Conclusion: A long-term impact of the pandemic on ED use may be a decrease in the proportion of young or ill children.

Hyperleukocytosis (HL), defined by a peripheral white blood cell (WBC) count exceeding 100,000/mm3, is occasionally observed in childhood acute leukemia. The increased viscosity in the micro-circulation by HL and the interaction between the leukemic blasts and endometrium of blood vessels sometimes result in leukostasis. Leukostasis can incur life-threatening manifestations, such as respiratory distress, brain infarction and hemorrhage, and renal failure, needing an emergency care. Although early stage of leukostasis is difficult to detect due to nonspecific manifestations, an emergency care is mandatory because leukostasis can proceed to a fatal course. Initial management includes an aggressive fluid therapy that can reduce WBC count, and prevent other metabolic complications implicated by HL. Packed red blood cells should be judiciously transfused because it increases blood viscosity. Conversely, transfusion of platelet concentrates or fresh frozen plasma, which does not affect blood viscosity, is recommended for prevention of hemorrhage. To reduce tumor burden, leukapheresis or exchange transfusion is commonly performed. However, the efficacy is still controversial, and technical problems are present. Leukapheresis or exchange transfusion is recommended if WBC count is 200,000-300,000/mm3 or more, especially in acute myelocytic leukemia, or manifestations of leukostasis are present. In addition, early chemotherapy is the definite treatment of leukostasis.

Purpose: Kawasaki disease (KD) is a common, acute systemic vasculitis in children. Acute phase reactants (APRs) have been used to assist diagnosis, and to predict outcome in children with KD. However, it remains unknown on levels of APRs depending on duration of fever. We aimed to compare APR levels of children with KD who visited with < 5 days duration of fever and with ≥ 5 days. Methods: Children (≤ 15 years) with complete KD who visited the emergency department were enrolled from March 2012 through February 2018. The children were divided into the early (fever < 5 days) and late (fever ≥ 5 days) presenters. The baseline characteristics, APR levels, such as platelet count, and outcomes were compared between the 2 groups. Results: A total of 145 children with complete KD were enrolled. Median age was 27.0 (interquartile range [IQR], 12.0-46.5) months, and boys accounted for 60.0%. The early presenters (63 [43.4%]) had a younger age (17.0 [IQR, 7.0-45.0] vs. 32.5 [IQR, 14.0-48.0] months; P = 0.006), shorter duration of fever (3.0 [IQR, 2.0-4.0] vs. 6.0 [IQR, 5.0-7.0] days; P < 0.001), and a lower platelet count (336.7 ± 105.2 [× 103/μL] vs. 381.6 ± 121.8 [× 103/μL], P = 0.02) than the late presenters. The other APR levels, and frequency of resistance to intravenous immunoglobulin and coronary artery abnormalities showed no differences between the 2 groups. Conclusion: Children with KD who visited with < 5 days duration of fever had a lower platelet count compared to those with ≥ 5 days. No differences were found in the other APR levels and the outcomes. It may be necessary to consider the differences in APR levels depending on duration of fever when treating children with KD.

The frequency of procedures in the emergency department has increased with changes in the medical environment and the demands of the times. Especially in children, sedation and analgesia are often inevitable due to the difficulty in seeking cooperation. Procedural sedation and analgesia is essential for successful completion of procedure, but the medical personnel who perform it must be prepared for complications caused by medications. Safe procedural sedation and analgesia requires well-trained medical personnel and well-prepared equipment, including appropriate patient assessments and choice of medications, faithful monitoring, and resuscitation. This review focuses on understanding of sedation processes, patient evaluation, medications, and monitoring.

Button battery ingestion requires emergency endoscopic removal since severe complications, such as esophageal perforation, can develop within 4 hours of the ingestion. Given that guardians do not witness the children’s foreign body ingestion 40% of the time, physicians can only guess what was swallowed based on plain radiography. We report a case of a 45-month-oldboy who visited the emergency department after swallowing an unknown foreign body and whose radiographs showed “circle-within-a-circle appearance” on the anteroposterior view and “step-off appearance” on the lateral view, suggesting button battery ingestion. We conducted emergency endoscopic removal, and found stacked coins mimicking a button battery on the radiographs. The coins were pushed into the stomach and came out through defecation 3 weeks later without further complications. Distinguishing between stacked coins and a button battery through radiography may help avoid unnecessary emergency endoscopy.

Purpose: The authors aimed to investigate the utility of blood culture (BC) for children with simple febrile seizure (SFS) in the emergency department (ED) in the post-10/13-valent pneumococcal conjugate vaccine (PCV) era. Methods: This study was performed at the ED of a tertiary care university-affiliated women and children’s hospital, and involved 3,237 previously healthy children aged 6-60 months who visited the ED with SFS from January 2013 through December 2017. The SFS was defined according to the International Classification of Diseases, 11th Revision codes related to seizure. The children were divided into 2 groups according to the vaccination rates of the period of their visit: the 70-PCV (70%, 2013-2014) and 97-PCV (97%, 2015-2017) groups. The primary outcome was the yield, defined as a true positivity of BC. In addition, we collected information on baseline characteristics, ED length of stay, inflammatory biomarkers, and ED outcomes. Results: Of the 1,578 children with SFS who underwent BC, 1,357 belonged to the 97-PCV group. The median age of the study population was 22 months (interquartile range, 16.0-30.0), and 935 children (59.3%) were boys. Of the 41 children (2.6%) with positive BC results, 3 had the yield (0.2%): Staphylococcus aureus in 2 children and Streptococcus pneumoniae in the other. All 3 children belonged to the 97-PCV group. There were 38 contaminated BCs (2.4%; 95% confidence interval, 1.6%-3.2%). The 97-PCV group showed a shorter median ED length of stay (166.0 minutes [108.0-279.5] vs. 143.0 [109.5-209.5]; P = 0.010) and a lower rate of hospitalization (39.4% vs. 12.8%; P < 0.001). No differences between the 2 groups were found in the baseline characteristics and biomarkers. Conclusion: This study suggests a low utility of BC in previously healthy children with SFS in emergency settings in the post-10/13-valent PCV era.

Purpose: We aimed to analyze the clinical characteristics, recurrence, neurological outcomes, and the impact of coronavirus disease 2019 pandemic in children who visited 2 emergency departments (EDs) with febrile seizure (FS). Methods: We retrospectively reviewed medical records of 3,172 episodes, involving 2,510 children aged 6-60 months whose diagnoses were FSs at the EDs in 2 hospitals from 2013 through 2022. Through the review, we analyzed clinical characteristics and associated factors for the recurrence of FS. As a sub-analysis, the variables were compared between before (2017-2019) and during (2020-2022) the pandemic. Results: A total of 3,172 FS-related visits to the EDs were found in 2,510 children. Of these, 890 children (35.5%) underwent recurrences of FS. The recurrence of FS was associated with boys (63.3% vs. 57.8%; P = 0.007), seizures lasting longer than 5 minutes (16.6% vs. 12.7%; P = 0.007), family history of FS (23.7% vs. 16.2%; P < 0.001), complex FS (13.3% vs. 8.0%; P < 0.001), and epilepsy diagnosed thereafter (9.1% vs. 3.0%; P < 0.001). During the pandemic, we noted a decrease in the number of FS-related visits to the EDs (from 1,274 to 383), an increase in the percentage of complex FS (9.3% vs. 13.8%; P = 0.012), and a decrease in the percentage of recurrent FS (49.4% vs. 33.4%; P < 0.001), compared to before the pandemic. Conclusion: Our study identified factors associated with recurrence of FS, and confirmed the increase in complex FS with the decrease in the recurrence during the coronavirus disease 2019 pandemic. These findings could be helpful when caring for children with FS in EDs.
