Introduction: Central venous catheters are more common with advanced treatments for a variety of conditions. These catheters may need to be repaired after local damage. This has been performed by those more involved with catheter placement such as pediatric surgeons and interventional radiologists. Gastroenterologists who treat many of these patients have also been involved with catheter repair. Repair by pediatric emergency physicians has not been explored. Such repairs by the emergency physician may be time saving and avoid unnecessary admissions.

Methods: This was a retrospective study of a single center's experience with catheter repair. The performers and outcomes were compared.

Results: During the study period, 52 catheter repairs were performed on 7 children. Forty of the repairs were performed by a pediatric emergency physician, 5 by pediatric surgeons, and 5 by interventional radiology. All but 1 repair was successful. Infectious complications were reported in 3 cases. None required catheter removal. The length of stay was significantly shorter for repair by emergency physician.

Conclusions: Central line catheter repair can be performed successfully by pediatric emergency physician with minimal complications. A dedicated process of repair tutoring is required and may avoid infectious complications.

Objectives: Early shock reversal is crucial to improve patient outcomes. Capillary refill time (CRT) is clinically important to identify and monitor shock in children but has issues with inconsistency. To minimize inconsistency, we evaluated a CRT monitoring system using an automated compression device. Our objective was to determine proper compression pressure in children.

Methods: Clinician force for CRT was collected during manual CRT measurement as a reference for automated compression in a previous study (12.9 N, 95% confidence interval, 12.5-13.4; n = 454). An automated compression device with a soft inflation bladder was fitted with a force sensor. We evaluated the effectiveness of the automated pressure to eliminate pulsatile blood flow from the distal phalange. Median and variance of CRT analysis at each pressure was compared.

Results: A comparison of pressures at 300 to 500 mm Hg on a simulated finger yielded a force of 5 to 10 N, and these pressures were subsequently used for automated compression for CRT. Automated compression was tested in 44 subjects (median age, 33 months; interquartile range [IQR], 14-56 months). At interim analysis of 17 subjects, there was significant difference in the waveform with residual pulsatile blood flow (9/50: 18% at 300 mm Hg, 5/50:10% at 400 mm Hg, 0/51: 0% at 500 mm Hg, P = 0.008). With subsequent enrollment of 27 subjects at 400 and 500 mm Hg, none had residual pulsatile blood flow. There was no difference in the CRT: median 1.8 (IQR, 1.06-2.875) in 400 mm Hg vs median 1.87 (IQR, 1.25-2.8325) in 500 mm Hg, P = 0.81. The variance of CRT was significantly larger in 400 mm Hg: 2.99 in 400 mm Hg vs. 1.35 in 500 mm Hg, P = 0.02, Levene's test. Intraclass correlation coefficient for automated CRT was 0.56 at 400 mm Hg and 0.78 at 500 mm Hg.

Conclusions: Using clinician CRT measurement data, we determined either 400 or 500 mm Hg is an appropriate pressure for automated CRT, although 500 mm Hg demonstrates superior consistency.

Abstract: Point-of-care ultrasound (POCUS) use has grown rapidly in the field of pediatric emergency medicine (PEM). Despite its growth, there continues to be a need for leaders in PEM POCUS to support ongoing education and advancement of providers within this field. We have developed a novel combined PEM POCUS fellowship that has successfully produced one graduate and a second will graduate in June 2023. We describe the implementation of this model as a potential option that institutions could use as a framework to support other trainees. This could alleviate some barriers for future trainees who seek advanced POCUS training and advance this growing field.

Objectives: The objectives are to determine whether diphenhydramine coadministered with prochlorperazine versus prochlorperazine only is associated with a difference in the risk of migraine treatment failure, as measured by the need for additional therapy, hospitalization rates, and 72-hour return rates, and to compare extrapyramidal adverse effects between groups.

Methods: Retrospective cohort of patients aged 7 to 18 years treated in the emergency department for migraines using prochlorperazine with or without diphenhydramine between 2013 and 2019. Patients were included if they had International Classification of Diseases, Ninth or Tenth Revision, codes for migraine or unspecified headache and were treated with prochlorperazine as part of their initial migraine therapy. Data collected included demographics, medications administered, pain scores, neuroimaging, disposition, return visits, and documentation of extrapyramidal adverse effects. Multivariable logistic regression was used to estimate the association between diphenhydramine coadministration and each of the outcomes.

Results: A total of 1683 patients were included. Overall, 13% required additional therapy with a 16.7% admission rate and a 72-hour return rate of 5.3%. There was no association between initial treatment with diphenhydramine and the odds of additional therapy (adjusted odds ratio [aOR], 0.74 [95% confidence interval {CI}, 0.53-1.03]), admission rates (aOR, 1.22 [95% CI, 0.89-1.67]), or return visit rates (aOR, 0.91 [95% CI, 0.55-1.51]). Extrapyramidal adverse effects occurred in 2.4% of patients in the prochlorperazine group and 0% in the prochlorperazine with diphenhydramine group.

Conclusions: There was no association between diphenhydramine coadministration and the need for additional therapy, 72-hour return visit rates or admission rates. Extrapyramidal effects did not occur in patients treated with diphenhydramine.

Objective: We sought to describe patterns of and indications for surgical specialty consultation for facial laceration repair in pediatric emergency departments (PEDs).

Methods: We performed a multicenter survey of PED leadership throughout the United States and Canada evaluating the practice patterns of surgical specialty consultation for patients presenting for facial lacerations requiring repair. We measured demographics of PEDs, factors influencing the decision to obtain a surgical specialty consultation, and the presence and components of consultation guidelines. Factors related to consultation were ranked on a Likert scale from 1 to 5 (1 = Not at all important, 5 = Extremely important). We evaluated relationships between reported rates of surgical specialty consultation and PED region, annual PED volume, and reported factors associated with PED consultation.

Results: Survey responses were received from 67/124 (54%) queried PEDs. The median self-reported rate of surgical specialty consultation for facial lacerations was 10% and ranged from 1% to 70%, with resident physicians performing the repair 71% of the time a subspecialist was consulted. There was regional variability in specialty consultation, with the highest and lowest rate in the Midwest and Canada, respectively ( P = 0.03). The top 4 influential factors prompting consultation with the highest percentage of responses of "Extremely Important" or "Very Important" were: discretion of the physician caring for the patient (95%), parental preference (39%), limited PED resources (32%), and patient requires sedation (32%). Surgical specialty consult guidelines were used in only 6% of PEDs with consensus that depth necessitating more than 2-layer repair or involvement of critical structures should prompt consultation.

Conclusions: Surgical specialty usage in the management of patients who present with facial lacerations to PEDs has significant variation related to patient, provider, and department-level factors that influence the decision to consult. Lack of consult guidelines represent a potential opportunity to standardize care delivery to this common presentation.

Abstract: Point-of-care ultrasound was used in a child presenting to the emergency department with progressively worsening left eyelid swelling. The early use of ultrasound was helpful in detecting a soft tissue mass that is exhibiting pressure effect on the eyeball. Point-of-care ultrasound helped expedite advanced imaging and consultation with the specialist. The patient eventually had a biopsy and was diagnosed with idiopathic orbital inflammation.

Objectives: Asthma is a leading cause of pediatric emergency department visits, yet few tools exist to objectively measure asthma severity. Diaphragmatic ultrasound (DUS) is a novel method of assessing respiratory distress; however, data are lacking for children.Our primary aim was to determine if diaphragmatic excursion (DE), diaphragmatic thickening (DT), or diaphragmatic thickening fraction (TF) correlated with asthma severity as determined by the Pediatric Respiratory Assessment Measure (PRAM) score. Secondarily, we examined if these parameters correlated with need for respiratory support and evaluated interrater reliability.

Methods: We conducted a prospective study of children 5-18 years presenting to a pediatric emergency department with an asthma exacerbation. Diaphragmatic ultrasound was performed by a trained pediatric emergency medicine sonologist in subcostal (DE) and midaxillary (DT). Thickening fraction was calculated from DT values as previously described in literature. To evaluate interrater reliability, a subset of subjects had DUS performed by a second sonologist.

Results: We enrolled 47 subjects for a total of 51 encounters. The mean age was 9.1 ± 3.7 years. Twenty-five (49%) had mild, 24 (47%) had moderate, and 2 (4%) had severe asthma. There was a significant difference in midaxillary DT and TF between children with mild and moderate asthma ( P = 0.02; mean difference, 0.2 mm; 95% confidence interval [CI], 0.03-0.4 and P = 0.02; mean difference, 0.11 mm; 95% CI, 0.02-0.2, respectively). No difference was found in subcostal DE ( P = 0.43; mean difference, 1.4 mm; 95% CI, -2.1 to 4.8). No association was found between use of positive pressure and DUS parameters. Fourteen encounters had 2 sonologists perform DUS, with strong interrater reliability found for midaxillary DT (Pearson correlation, 0.56) and poor association for subcostal DE (Pearson correlation, 0.18).

Conclusions: In this pilot study, we conclude that DUS may be helpful in assessing severity of asthma. The midaxillary view assessment for DT and TF had the best correlation with asthma severity and the best interrater reliability. Future studies may benefit from focusing on the midaxillary view for DT and TF.

Background: A removable brace with home management is widely accepted treatment for distal radius buckle fractures, which most commonly involve the dorsal cortex.

Purpose: The purpose of this study is to determine if a removable brace and home management treatment is safe for volar distal radius buckle fractures.

Materials and methods: Isolated distal radius buckle fractures in children (3-16 years) diagnosed at an acute care visit (April 1, 2019 to May 31, 2022) were identified. Final diagnosis was confirmed using strict criteria including cortical buckling without cortical breach or physeal involvement. Cortical buckling was categorized as either dorsal or volar. Demographic data, mechanism of injury, treatment, and any complications were recorded and analyzed.

Results: Three hundred thirty-three fractures were either dorsal (254, 76%) or volar (79, 24%) buckle fractures. Mean age (SD) for volar fractures (9.3 [2.2 years]; range, 4-14 years) was significantly higher than for dorsal fractures (8.5 (3.0 years); range, 3-15 years; P = 0.012). More girls had volar fractures (48 [60%], P = 0.006). Most fractures occurred after a standing-height fall. Two hundred forty-four (96%) dorsal and 76 (96%) volar fractures were initially treated with a removable brace. Two hundred fourteen (84%) dorsal and 66 (84%) volar fractures had orthopedic follow-up. Brace treatment continued for 167 (167/204, 82%) dorsal and 56 (56/63, 89%) volar fractures. Treatment changed from initial brace to cast for 37 (37/204, 18%) dorsal fractures and 7 (7/63, 11%) volar fractures, influenced by caregiver preference and/or sport participation requirements. Only 1 (1/79, 1%) patient with a volar fracture returned for an additional visit for persistent pain.

Conclusions: When diagnosis of volar buckle fracture is made using the same strict criteria used for dorsal buckle fractures, removable brace and home management treatment is safe. Shared decision making with caregivers may alter buckle fracture treatment.

Objectives: Boarding of adolescent patients with mental health concerns requiring ongoing observation and treatment is of increasing concern across US emergency departments. The objective was a proof of concept of developing an adolescent psychiatric emergency unit and assessment of the impact of this unit on lengths of stay (LOS).

Methods: We describe the creation of the unit designed to allow safe assessment and boarding of patients, and appropriate interventions and services, while arranging transfer to inpatient facility or safe discharge home. Using a precreation and postcreation analysis and comparison with a similar facility that did not create such a unit, we utilized linear regression to investigate the primary outcome of total length of stay and secondary outcomes of psychiatric emergency department and pediatric emergency department length of stay for both unit-eligible patients and all patients.

Results: The overall length of stay was not associated with a statistically significant change for unit-eligible patients; however, there was a significant decrease in the pediatric emergency department LOS for unit-eligible patients. This was associated with a decrease in beds lost to boarding in the pediatric emergency department of 544 hours per month.

Conclusions: Creation of an adolescent psychiatric emergency unit without allotment of significant additional resources is an option to decrease pediatric emergency department boarding times for adolescent patients requiring ongoing emergent therapy for mental health concerns.
