Ideal chest compression site for cardiopulmonary resuscitation in fontan circulation patients with dextrocardia.

BACKGROUND: We aimed to identify the ideal chest compression site for cardiopulmonary resuscitation (CPR) in patients with a single ventricle with dextrocardia corrected by Fontan surgery. METHODS: The most recent stored chest computed tomography images of all patients with a single ventricle who underwent Fontan surgery were retrospectively analysed. We reported that the ideal chest compression site is the largest part of the compressed single ventricle. To identify the ideal chest compression site, we measured the distance from the midline of the sternum to the point of the maximum sagittal area of the single ventricle as a deviation and calculated the area fraction of the compressed structures. RESULTS: 58 patients (67.2% male) were analysed. The mean right deviation from the midline of the sternum to the ideal compression site was similar to the mean sternum width (32.85 ± 15.61 vs. 31.05 ± 6.75 mm). When chest compression was performed at the ideal site, the area fraction of the single ventricle significantly increased by 7%, which was greater than that of conventional compression (0.15 ± 0.10 vs. 0.22 ± 0.11, P < 0.05). CONCLUSIONS: When performing CPR on a patient with Fontan circulation with dextrocardia, right-sided chest compression may be better than the conventional location.

The Association Between Inter-Hospital Transfers and the Prognosis of Pediatric Injury in the Emergency Department.

BACKGROUND: Inter-hospital transfers of severely injured patients are inevitable due to limited resources. We investigated the association between inter-hospital transfer and the prognosis of pediatric injury using the Korean multi-institutional injury registry. METHODS: This retrospective observational study was conducted from January 2013 to December 2017; data for hospitalized subjects aged < 18 years were extracted from the Emergency Department-based Injury in Depth Surveillance database, in which 22 hospitals are participating as of 2022. The survival rates of the direct transfer group and the inter-hospital transfer group were compared, and risk factors affecting 30-day mortality and 72- hour mortality were analyzed. RESULTS: The total number of study subjects was 18,518, and the transfer rate between hospitals was 14.5%. The overall mortality rate was 2.3% (n = 422), the 72-hour mortality was 1.7% (n = 315) and the 30-day mortality rate was 2.2% (n = 407). The Kaplan-Meier survival curve revealed a lower survival rate in the inter-hospital transfer group than in the direct visit group (log-rank, P < 0.001). Cox proportional hazards regression analysis showed that inter-hospital transfer group had a higher 30-day mortality rate and 72-hour mortality (hazard ratio [HR], 1.681; 95% confidence interval [CI], 1.232-2.294 and HR, 1.951; 95% CI, 1.299-2.930) than direct visit group when adjusting for age, sex, injury severity, and head injury. CONCLUSION: Among the pediatric injured patients requiring hospitalization, inter-hospital transfer in the emergency department was associated with the 30-day mortality rate and 72-hour mortality rate in Korea.

The Barriers to Recognizing and Reporting Child Physical Abuse by Emergency Physicians and Associated Factors.

BACKGROUND: Although the reporting rate of child abuse is increasing every year, the child abuse detection rate is 3.81% as of 2019 in Korea, which is significantly lower than that of developed countries for child rights. OBJECTIVE: We investigated the associated factors with barriers that emergency physicians face in recognizing and reporting cases of child abuse. METHODS: From May to July 2022, 240 emergency physicians working in the 15 emergency department were asked to participate in the survey via email. The questionnaire included the respondent's basic information, treatment experience for child abuse, reasons for reporting or not reporting, and opinions on measures to increase the reporting rate. We conducted a logistic regression analysis to discern the factors contributing to underreporting. RESULTS: Seventy-one individuals were included in the analysis, after excluding those who had never encountered suspected cases of child abuse. A multivariable logistic regression was performed with the above variables, and although it was not statistically significant, there was a tendency for workers to report well when working at a pediatric emergency department (odds ratio [95% confidence interval], 3.97 [0.98-16.09]). The primary reason for reporting suspected abuse was the pattern of damage suspected of abuse. The first reason for not reporting suspected abuse was because they were not sure it was child abuse. Respondents answered that to report better, a quick and appropriate response from the police and confidentiality of the reporter were needed. CONCLUSIONS: Physicians in pediatric emergency departments demonstrated a tendency for more proactive reporting suspected cases of child abuse.

Predictors of Caregiver Satisfaction With Pediatric Laceration Repair in the Pediatric Emergency Department.

OBJECTIVES: The objective of this study was to define the care factors that are important to caregivers' satisfaction with pediatric laceration repair and the overall emergency department (ED) experience. METHODS: This was a cross-sectional observation study performed in an urban tertiary hospital. The caregivers of patients younger than 18 years who presented to the ED for laceration repair completed a survey. Demographic data were analyzed. Univariate and multivariate logistic regressions were used to determine the factors related to satisfaction with the laceration repair and the overall ED experience. RESULTS: Fifty-five caregivers were enrolled. Most of the children had facial lacerations (n = 44, 80%). The median length of ED stay was 181 minutes (interquartile range [IQR], 157-208 minutes). The children's median age was 41.8 months (IQR, 23-91 months); the caregivers' median age was 37 years (IQR, 35-41 years). Most lacerations were repaired by plastic surgeons (81.8%). In the multivariate regression analysis, preparation before the procedure, mid-income family, caring attitude of the nurse, cosmetic outcome, and measures to control the patient's anxiety were significantly related to the caregiver's satisfaction with laceration repair (P < 0.05), whereas preparation before the procedure and ED environment were significantly related to the caregiver's satisfaction with the overall ED experience (P < 0.05). CONCLUSIONS: Preparation before the procedure was significantly related to the caregiver's satisfaction with both pediatric laceration repair and the overall PED experience. The strongest predictors were cosmetic outcome for laceration repair and preparation for the procedure for the overall PED experience. Our findings suggest that improvements in various aspects will increase parent satisfaction.

Factors contributing to uncertainty in paediatric abdominal ultrasound reports in the paediatric emergency department.

BACKGROUND: Abdominal pain, which is a common cause of children presenting to the paediatric emergency department (PED), is often evaluated by ultrasonography (US). However, uncertainty in US reports may necessitate additional imaging. OBJECTIVE: In this study, we evaluated factors contributing to uncertainty in paediatric abdominal US reports in the PED. MATERIALS AND METHODS: This retrospective cohort study included children younger than 18 years of age who underwent abdominal US in the PED of the study hospital between January 2017 and December 2019. After exclusion, the researchers manually reviewed and classified all US reports as 'certain' or 'uncertain'. Univariate and multivariate logistic regression analyses were performed to identify the factors contributing to uncertain reports. RESULTS: In total, 1006 patients were included in the final analysis., 796 patients were tagged as having certain reports, and 210 as having uncertain reports. Children with uncertain reports had a significantly higher rate of undergoing an additional computed tomography (CT) scan (31.0% vs. 2.5%, p < 0.001) and a longer PED median length of stay (321.0 (Interquartile range (IQR); 211.3-441.5) minutes vs. 284.5 (IQR; 191.8-439.5) minutes, p = 0.042). After logistic regression, US performed by a radiology resident (odds ratio, 5.01; 95% confidence interval, 3.63-7.15) was the most significant factor contributing to uncertainty in paediatric abdominal US reports followed by obesity and age. CONCLUSION: Several factors contribute to uncertainty in paediatric abdominal US reports. Uncertain radiological reports increase the likelihood of additional CT scans. Measures to improve the clarity of radiological reports must be considered to improve the quality of care for children visiting the PED.

Association between focused cardiac ultrasound and time to furosemide administration in acute heart failure.

BACKGROUND: Heart failure (HF) is a global health burden, and its management in the emergency department (ED) is important. This study aimed to evaluate the association between focused cardiac ultrasound (FoCUS) and early administration of diuretics in patients with acute HF admitted to the ED. METHODS: This retrospective observational study was conducted at a tertiary academic hospital. Patients with acute HF patients who were admitted to the ED and receiving intravenous medication between January 2018 and December 2019 were enrolled. The main exposure was a FoCUS examination performed within 2 h of ED triage. The primary outcome was the time to furosemide administration. RESULTS: Of 1154 patients with acute HF, 787 were included in the study, with 116 of them having undergone FoCUS. The time to furosemide was significantly shorter in the FoCUS group (median time (q1-q3), 112 min; range, 65-163 min) compared to the non-FoCUS group (median time, 131 min; range, 71-229 min). In the multivariable logistic regression analysis adjusting for age, sex, chief complaint, mode of arrival, triage level, shock status, and desaturation at triage, early administration of furosemide within 2 h from triage was significantly higher in the FoCUS group (adjusted odds ratio, 1.63; 95% confidence intervals, 1.04-2.55) than in the non-FoCUS group. CONCLUSIONS: Early administration of intravenous furosemide was associated with FoCUS examination in patients with acute HF admitted to the ED. An early screening protocol could be useful for improving levels in clinical practice at EDs.

Tablet personal computer distraction during intravenous placement for young children in the pediatric emergency department: A pilot study.

BACKGROUND: Intravenous (IV) placement is a common procedure experienced by children visiting the pediatric emergency department (PED). However, uncontrolled anxiety and pain cause children to interfere with the procedure. In this pilot study, we sought to evaluate the effectiveness of tablet personal computers as a distraction method during IV placement. METHODS: This is a single-center pilot study conducted at a tertiary teaching hospital. Children visiting the PED were eligible if they were aged 3-5 years and required IV placement during the PED visit. After written consent was obtained from the guardian, the child was randomly assigned to a control group or an intervention group. For the intervention group, an animated video was played via tablet PC during IV placement. For both groups, children's anxiety, heart rate, and pain scale scores (the Face, Legs, Activity, Cry, Consolability and Evaluation Enfant Douleur) and guardian satisfaction were recorded. RESULTS: 22 children were eligible for the final analysis. There was no significant difference in the pain scale scores between the two groups, with the exception of the degree of pain relief after the procedure measured using Evaluation Enfant Douleur (intervention group: 6.0, interquartile range (IQR): 4.2-6.8, and control group; 3.0, IQR: 2.0-3.8, P = 0.011) and Face, Legs, Activity, Cry, Consolability (intervention group: 4.0, IQR: 4.0-4.2 and control group; 3.0, IQR: 1.5-3.5, P = 0.043). CONCLUSION: In this pilot study, distraction using tablet personal computers may have reduced children's distress during the recovery phase after venipuncture. Further study with a larger sample size and different methods of distraction is essential.

"Weighing Cam": A New Mobile Application for Weight Estimation in Pediatric Resuscitation.

Objective: We evaluated the validity of a newly developed mobile application (i.e. the Weighing Cam) for pediatric weight estimation compared with that of the Broselow tape. Methods: We developed an application that estimates the weight of pediatric patients using a smartphone camera and displays the drug dosage, device size, and defibrillation energy on the screen of the smartphone. We enrolled a convenience sample of pediatric patients aged <16 years who presented at two pediatric emergency departments of two tertiary academic hospitals in South Korea. The pediatric patients' heights and weights were measured; then, one researcher estimated the weights using the application. Using the measured height, we determined the weight estimated by the Broselow tape. We compared the estimated measurements by determining the mean percentage error (MPE), mean absolute percentage error, root mean square percentage error, and percentages predicted within 10% and 20% of the actual. Results: In total, 480 patients were enrolled in 16 age categories, each with 15 males and 15 females of different ages. The Weighing Cam demonstrated a lower bias (mean difference: -1.98% [95% confidence interval -2.91% to -1.05%] for MPE) and a higher proportion of estimated weights within 10% of the actual weights than the Broselow tape (mean difference: 9.1% [95% confidence interval 3.0% to 15.1%]). The Weighing Cam showed better performance in terms of accuracy and precision than the Broselow tape in all subgroups stratified by age or body mass index percentile. Conclusions: The Weighing Cam may estimate pediatric patients' weights more accurately than the Broselow tape. The Weighing Cam may be useful for pediatric resuscitation in both prehospital and hospital settings.

Delayed adenosine therapy is associated with the refractory supraventricular tachycardia in children.

OBJECTIVES: To study the association of time intervals on adenosine therapy with the occurrence of refractory supraventricular tachycardia (SVT) in children. METHODS: We reviewed 334 episodes of presumed SVT requiring adenosine in children (<18 years) who visited 4 academic hospital emergency departments (EDs) from July 2013 through June 2017. Refractory SVT was defined as an SVT episode persisting after 2 doses of adenosine. Clinical and electrocardiographic findings, and symptom-to-adenosine (symptom-to-ED plus ED-to-adenosine) time of refractory and responsive SVT episodes were compared. Multivariable logistic regression was performed to identify factors associated with the occurrence of refractory SVT. RESULTS: Of 211 SVT episodes, 42 episodes of refractory SVT (19.9%) were noted (overall sinus conversion rate, 79.6%). The refractory episodes were associated with a higher frequency of known structural heart diseases (9.5% vs. 1.8%; P = 0.030) and a longer median ED-to-adenosine time (15.5 vs. 11.0 min; P = 0.018). The association of the ED-to-adenosine time with refractory SVT remained significant after adjustment (for increment of 1 min; aOR, 1.02; 95% CI, 1.007-1.04). CONCLUSIONS: Delayed adenosine therapy is associated with the occurrence of refractory SVT in children, supporting the need for prompt adenosine therapy.

Pediatric Injuries in Kids Cafés and Risk Factors for Significant Injuries: a 6-Year Cross-Sectional Study Using a Multicenter Injury Registry in Korea.

BACKGROUND: A kids café is a popular indoor playground in Korea that combines a playground for young children and a café for their caregivers. There have been no national reports about kids café-related injuries in Korea. This study investigated kids café-related injuries in Korea registered in a multicenter injury surveillance database and analyzed the risk factors for significant kids café-related injuries. METHODS: A multicenter cross-sectional study was performed using the Emergency Department-based Injury In-depth Surveillance registry in Korea between 2011 and 2016. Significant injury was defined as an injury requiring hospitalization or surgery. A multivariable logistic regression model was used to obtain the adjusted odds ratios (aORs) for factors associated with significant kids café-related injuries. RESULTS: Among 1,537,617 injured patients, we extracted 891 patients who were injured in kids cafés. Of these, 46 (5.2%) were admitted, and 39 (4.4%) underwent surgery. The most common injured anatomical site, injury type, and mechanism were lower extremity (28.2%), superficial injury (27.2%), and slip (27.1%), respectively. Among injury-inducing factors, significant injuries were most commonly caused by a trampoline (28.1%), and rock climbing equipment was the only risk factor in a kids café that led to significant injury after adjusting for age, sex, injury mechanism, and injured anatomical sites (aOR, 14.94; 95% confidence interval, 1.51-147.72). CONCLUSION: The rock climbing equipment in a kids café can cause serious injury to children. Establishing safety regulations for rock climbing equipment in kids cafés may have the greatest impact in reducing significant injuries requiring hospitalization or surgery.

Two-Thumb Encircling Technique With a Novel Compression Assist Device Provides Safe and Effective Chest Compressions in Infants.

OBJECTIVE: Currently, 2-thumb encircling technique is recommended in 2-rescuer infant cardiopulmonary resuscitation (CPR). However, many complications can occur during CPR. Therefore, we developed a novel compression assist device (Reheart) that can reduce chest compression area and determined whether using our device provides better compression quality. METHODS: A novel compression assist device consists of 2 parts. The upper part was designed to put 2 thumbs together in the thumb sleeves, and the lower part was designed based on a circular rubber plate with a 2.0-cm diameter to confine compression area. Infant manikin CPR simulations using the 2-thumb encircling technique with Reheart and without Reheart were sequentially performed by participants in randomized crossover fashion. RESULTS: A total of 32 health care providers were included. The average age of the participants was 30.2 ± 3.5 years, and 21 participants (65.6%) were male. The accuracy in the Reheart group was better than that in the conventional group (proportion of compression on target area, 52.5% ± 13.2% vs 35.4% ± 17.6%; P < 0.001). The difference in the rates of chest compressions between the 2 groups was not significant (119.6 ± 14.4 vs 120.7 ± 14.0 compressions/min, P = 0.59). The depth of chest compressions was also not significantly different between the 2 groups (34.5 mm [33.6-34.9 mm] vs 34.2 mm [33.0-34.9 mm], P = 0.32). CONCLUSIONS: Our new compression assist device can help provide safe and effective chest compressions during 2-rescuer infant CPR.

A Novel Infant Chest Compression Assist Device Using a Palm Rather Than Fingers: A Randomized Crossover Trial.

Objective: We developed a novel compression assist device (palm presser) to perform chest compressions using a palm in infant cardiopulmonary resuscitation (CPR). We hypothesized that the palm presser will increase compression depth without increasing hands-off time and will reduce rescuer fatigue compared with the two-finger technique (TFT).Methods: In this randomized crossover manikin trial, participants performed two minutes of CPR with a 30:2 compression:ventilation ratio using the palm presser and the TFT in randomized sequence on an infant manikin. CPR parameters, including compression depth and hands-off time, were collected to compare CPR quality between the palm presser and the TFT. The linear mixed-effect model was used to control the carryover effect of a crossover design in the analysis of CPR parameters. To evaluate rescuer fatigue, we compared changes in compression depth over time and calculated the odds of sufficiently deep compressions over time between the two groups.Results: The palm presser resulted in greater mean compression depth (41.5 ± 1.6 mm vs. 36.8 ± 5.5 mm, p < 0.001), greater sufficiently deep compressions (80.9 ± 27.8% vs. 42.4 ± 35.4%, p < 0.001), and better correct hand position (99.9 ± 0.5% vs. 83.9 ± 25.3%, p = 0.013) than the TFT. Total compressions, compression rate, total ventilations, volume of ventilations, and hands-off time were not significantly different between the two groups. The mean change in compression depth over time was greater with the TFT than with the palm presser (regression coefficient: -0.024 [95% CI -0.030 to -0.018] vs. -0.004 [95% CI -0.006 to -0.002]). The odds of a compression depth greater than 40 mm increased 2.8 times (95% CI 2.2 to 3.4) with the TFT during the first minute compared with the last minute, whereas the corresponding odds ratio when using the palm presser was not significantly different in the first and last minutes (OR: 1.2 [95% CI 0.9 to 1.5]).Conclusions: Compression with palm pressers resulted in greater compression depth without increasing hands-off time and reduced rescuer fatigue compared with compression with the TFT in simulated infant CPR with manikins.

Interexaminer reliability of pharyngeal injection and palatine tonsillar hypertrophy in a pediatric emergency department.

OBJECTIVES: To evaluate the interrater reliability of throat examinations in children according to the major and training stage. STUDY DESIGN: We performed a prospective observational study of interrater reliability. The participants included physicians with various amounts of experience and majors who were working in an urban, tertiary hospital. We collected 20 photos of the throats of children who presented to the pediatric emergency department (ED) and performed 2 surveys (with or without medical history). The primary outcome was the interrater agreement for pharyngeal injection (PI) and palatine tonsillar hypertrophy (PTH), and the secondary outcome was the interrater agreement for PI and PTH in subgroups of examiners divided by major and duration of clinical experience. RESULTS: Thirty-three examiners participated in this study. The overall percent agreement for PI was 0.669, and Fleiss' kappa was 0.296. The interrater reliability was similar before and after providing patients' medical history. The overall percent agreement for PTH was 0.408, and Kendall's W was 0.674. When the patients' medical history was provided, Kendall's W increased (0.692). In the subgroup analysis, Fleiss' kappa for PI ranged from 0.257 to 0.33, and Kendall's W for PTH ranged from 0.593 to 0.711. CONCLUSION: Examiners' agreement for PTH was more reliable than that for PI when evaluating children who visited the ED. The interrater reliability did not improve with increased clinical experience. These findings should be considered in the examination of pharyngeal pathology.

Efficacy of low-dose nebulized epinephrine as treatment for croup: A randomized, placebo-controlled, double-blind trial.

OBJECTIVE: Croup treatment usually involves a single dose of systemic dexamethasone combined with nebulized epinephrine. However, the optimal dose of l-epinephrine remains unclear. We examined whether a low dose (0.1 mg/kg) was inferior to the conventional dose (0.5 mg/kg) of 1:1000 nebulized l-epinephrine in patients with moderate to severe croup. METHODS: This randomized double-blind clinical non-inferiority trial was conducted in three pediatric emergency departments from May 2015 to October 2017. Children 6 months to 5 years old with moderate to severe croup (Westley scale scores 3-11) were eligible. Subjects were randomly assigned to the conventional dose (0.5 mg/kg: maximum 5 mg) or low dose (0.1 mg/kg; maximum 1 mg) group. All subjects received 0.6 mg/kg dexamethasone. Croup scores and other vital signs were measured before and at 30, 60, 90, and 120 min after nebulized l-epinephrine administration. The primary outcome was the change in croup score after 30 min. RESULTS: The final analysis included 84 patients. The groups did not differ significantly in terms of demographic parameters. At 30 min after treatment with nebulized l-epinephrine, the croup scores in both groups were significantly reduced from the baseline values (p < 0.05) and did not differ between the two groups (p = 0.42). Neither blood pressure nor heart rate differed between the two groups. CONCLUSIONS: Low-dose 1:1000 l-epinephrine was not inferior in croup score reduction to the conventional dose in patients with moderate to severe croup. Clinical trial No: NCT01664507, KCT0002318.

New decision formulas for predicting endotracheal tube depth in children: analysis of neck CT images.

INTRODUCTION: The purpose of this study was to construct a prediction model for endotracheal tube depth using neck CT images. METHODS: A retrospective image review was conducted that included patients who had undergone neck CT. Using sagittal neck CT images, we calculated the length between upper incisor and mid-trachea and then derived the model via regression analysis. The model was validated externally using chest radiographs of patients who had undergone endotracheal intubation. We compared performance of our model with that of other methods (Broselow tape and APLS formula) via Bland-Altman analysis and the percentage of estimations within 10% of the measured values. RESULTS: A total of 1111 children were included in this study. The tube depth obtained from CT images was linearly related to body weight (tube depth (cm)=5.5+0.5×body wt (kg)) in children younger than 1 year and to height (tube depth (cm)=3+0.1×height (cm)) in children older than 1 year. External validation demonstrated that our new model showed better agreement with the desired tube depth than Broselow tape and APLS formula. The mean differences in children younger than 1 year were 0.61 cm and -1.24 cm for our formula and Broselow tape, respectively. The mean differences in children older than 1 year were -0.43 cm, -1.98 and -1.64 cm for our formula, Broselow tape and APLS formula, respectively. The percentages of estimates within 10% of the measured values were 52.7% and 35.8% for our formula and Broselow tape in children younger than 1 year, respectively, and 54.3%, 33.8% and 37.2% for our formula, Broselow tape and APLS formula in children older than 1 year, respectively (P<0.01). CONCLUSION: Our new formula is useful and more accurate than the currently available methods.

Comparison of age-adjusted shock indices as predictors of injury severity in paediatric trauma patients immediately after emergency department triage: A report from the Korean multicentre registry.

INTRODUCTION: Shock index paediatric-adjusted (SIPA) was presented for early prediction of mortality and trauma team activation in paediatric trauma patients. However, the derived cut-offs of normal vital signs were based on old references. We established alternative SIPAs based on the other commonly used references and compared their predictive values. METHODS: We performed a retrospective review of all paediatric trauma patients aged 1-15 years in the Emergency Department (ED)-based Injury In-depth Surveillance (EDIIS) database from January 1, 2011 to December 31, 2019. A total of 4 types of SIPA values were obtained based on the references as follows: uSIPA based on the Nelson textbook of paediatrics 21st ed., SIATLS based on the ATLS 10th guideline, SIPALS based on the PALS 2020 guideline, and SIPA. In each SIPA group, the cut-off was established by dividing the group into 4 subgroups: toddler (age 1-3), preschooler (age 4-6), schooler (age 7-12), and teenager (age 13-15). We performed an ROC analysis and calculated the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) to compare the predicted values of each SIPA in mortality, ICU admission, and emergent surgery or intervention. RESULTS: A total of 332,271 patients were included. The proportion of patients with an elevated shock index was 14.9 % (n = 49,347) in SIPA, 22.8 % (n = 75,850) in uSIPA, 0.3 % (n = 1058) in SIATLS, and 4.3 % (n = 14,168) in SIPALS. For mortality, uSIPA achieved the highest sensitivity (57.0 %; 95 % confidence interval 56.9 %-57.2 %) compared to SIPA (49.4 %, 95 % CI 49.2 %-49.5 %), SIATLS (25.5 %, 95 % CI 25.4 %-25.7 %), and SIPALS (43.8 %, 95 % CI 43.7 %-44.0 %), but there were no significant differences in the negative predictive value (NPV) or area under the curve (AUC). The positive predictive value (PPV) was highest in SIATLS (5.7 %, 95 % CI 5.6 %-5.8 %) compared to SIPA (0.2 %, 95 % CI 0.2 %-0.3 %), uSIPA (0.2 %, 95 % CI 0.2 %-0.2 %), and SIPALS (0.7 %, 95 % CI 0.7 %-0.8 %). The same findings were presented in ICU admission and emergent operation or intervention. CONCLUSION: The ATLS-based shock index achieved the highest PPV and specificity compared to SIPA, uSIPA, and SIPALS for adverse outcomes in paediatric trauma.

Unpowered scooter injuries in children and risk factors for traumatic brain injuries: An 8-year cross-sectional study using a national registry in South Korea.

INTRODUCTION: Head trauma accounts for a large proportion of unpowered scooter injuries in children. Traumatic brain injury (TBI) is the leading cause of considerable mortality and morbidity in children, who are the main users of unpowered scooters. The aim of this study was to explore the characteristics of unpowered scooter injuries in children and to identify predictors of the occurrence of TBI. METHODS: A multicentre observational retrospective study was conducted using the Emergency Department-based Injury In-depth Surveillance (EDIIS) database in South Korea. Children aged 2 to 18 years old with unpowered scooter injuries between 2011 and 2018 were eligible for inclusion in this study, and the primary outcome was TBI defined based on the International Classification of Diseases, 10th Revision (ICD-10) code. RESULTS: The annual rate of unpowered scooter injuries per 1,000 injured patients increased throughout the study period from 1.4 in 2011 to 16.4 in 2018 (P for trend < 0.001). Of the 3,892 children who had unpowered scooter injuries, 353 (9.2 %) had TBI. Children were at a higher risk of unpowered scooter TBI if they were aged between 2 and 5 years (adjusted odds ratio [aOR]: 1.37; 95 % confidence interval (CI): 1.09-1.73), were male (aOR: 1.45; 95 % CI: 1.14-1.86), were injured either on sidewalks (aOR: 1.80; 95 % CI: 1.20-2.70) or on driveways (aOR: 2.31; 95 % CI: 1.41-3.79), and experienced a fall (aOR: 1.98; 95 % CI: 1.15-3.43). Additionally, children injured after a blunt force were at a lower risk of TBI (aOR: 0.28; 95 % CI: 0.15-0.53). CONCLUSION: Unpowered scooter injuries in children are increasing in South Korea. It is essential for younger children riding unpowered scooters to wear helmets and for caregivers to actively supervise their children to prevent TBI.

Effect of a Virtual Reality Environment Using a Domed Ceiling Screen on Procedural Pain During Intravenous Placement in Young Children: A Randomized Clinical Trial.

Importance: Distraction using virtual reality (VR) has been found to provide a clinically significant reduction in the experience of pain during various painful procedures. Commercially available VR systems usually require the user to wear a head-mounted display helmet, which can be challenging for young children, and whether VR can reduce pain during intravenous (IV) placement in young children is currently unknown. Objective: To determine whether a VR environment using a novel domed ceiling screen reduces distress among children over the course of IV placement compared with standard care in a pediatric emergency department. Design, Setting, and Participants: This randomized clinical trial was conducted from June 3, 2020, to February 8, 2021, at an urban tertiary academic children's hospital. Included were children aged 6 months to 4 years undergoing IV placement in the pediatric emergency department. Intervention: Children in the intervention group lay on a bed to experience a VR animation using a domed ceiling screen during the IV placement procedure, which was performed as usual. Children in the control group also lay on a bed during the procedure but did not view a VR animation. Main Outcomes and Measures: The primary outcome was pain scores measured using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale at 4 time points during IV placement: immediately after the child lay down on the bed (T1), the moment the tourniquet was applied (T2), the moment a sterile alcohol swab was applied (T3), and the moment the needle penetrated the skin (T4). Results: Of the 88 children included in the final analysis, 44 received VR distraction (median [IQR] age, 24.0 [14.5-44.0] months; 27 boys [61.4%]), and 44 received standard care (median [IQR] age, 23.0 [15.0-40.0] months; 26 boys [59.1%]). The median [IQR] FLACC scores at T4 were 6.0 (1.8-7.5) in the intervention group and 7.0 (5.5-7.8) in the control group. The ordinal logistic regression model showed that children in the VR intervention group vs the control group had a lower probability of higher FLACC scores (odds ratio, 0.53; 95% CI, 0.28-0.99; P = .046). Conclusions and Relevance: The findings of this trial indicate that displaying VR using a domed ceiling screen may be an effective distraction method that reduces distress in young children undergoing IV placement.
