Effect of Early vs Late Inguinal Hernia Repair on Serious Adverse Event Rates in Preterm Infants: A Randomized Clinical Trial.

Importance: Inguinal hernia repair in preterm infants is common and is associated with considerable morbidity. Whether the inguinal hernia should be repaired prior to or after discharge from the neonatal intensive care unit is controversial. Objective: To evaluate the safety of early vs late surgical repair for preterm infants with an inguinal hernia. Design, Setting, and Participants: A multicenter randomized clinical trial including preterm infants with inguinal hernia diagnosed during initial hospitalization was conducted between September 2013 and April 2021 at 39 US hospitals. Follow-up was completed on January 3, 2023. Interventions: In the early repair strategy, infants underwent inguinal hernia repair before neonatal intensive care unit discharge. In the late repair strategy, hernia repair was planned after discharge from the neonatal intensive care unit and when the infants were older than 55 weeks' postmenstrual age. Main Outcomes and Measures: The primary outcome was occurrence of any prespecified serious adverse event during the 10-month observation period (determined by a blinded adjudication committee). The secondary outcomes included the total number of days in the hospital during the 10-month observation period. Results: Among the 338 randomized infants (172 in the early repair group and 166 in the late repair group), 320 underwent operative repair (86% were male; 2% were Asian, 30% were Black, 16% were Hispanic, 59% were White, and race and ethnicity were unknown in 9% and 4%, respectively; the mean gestational age at birth was 26.6 weeks [SD, 2.8 weeks]; the mean postnatal age at enrollment was 12 weeks [SD, 5 weeks]). Among 308 infants (91%) with complete data (159 in the early repair group and 149 in the late repair group), 44 (28%) in the early repair group vs 27 (18%) in the late repair group had at least 1 serious adverse event (risk difference, -7.9% [95% credible interval, -16.9% to 0%]; 97% bayesian posterior probability of benefit with late repair). The median number of days in the hospital during the 10-month observation period was 19.0 days (IQR, 9.8 to 35.0 days) in the early repair group vs 16.0 days (IQR, 7.0 to 38.0 days) in the late repair group (82% posterior probability of benefit with late repair). In the prespecified subgroup analyses, the probability that late repair reduced the number of infants with at least 1 serious adverse event was higher in infants with a gestational age younger than 28 weeks and in those with bronchopulmonary dysplasia (99% probability of benefit in each subgroup). Conclusions and Relevance: Among preterm infants with inguinal hernia, the late repair strategy resulted in fewer infants having at least 1 serious adverse event. These findings support delaying inguinal hernia repair until after initial discharge from the neonatal intensive care unit. Trial Registration: ClinicalTrials.gov Identifier: NCT01678638.

USE OF A STATEWIDE SOLID ORGAN INJURY PROCOTCOL TO OPTIMIZE TRIAGE, TREATMENT, AND TRANSFER FOR PEDIATRIC ABDOMINAL TRAUMA.

BACKGROUND: The Utah Pediatric Trauma Network (UPTN) is a non-competitive collaboration of all 51 hospitals in the state of Utah with the purpose of improving pediatric trauma care. Created in 2019, UPTN has implemented evidence-based guidelines based on hospital resources and capabilities with quarterly review of data collected in a network-specific database. A blunt solid organ injury (SOI) protocol was developed to optimize treatment of these injuries statewide. The purpose of this study was to review the effectiveness of the SOI guideline. METHODS: The UPTN REDCap® database was retrospectively reviewed from 2021 through 2022. We compared admissions from the Level 1 pediatric trauma center (PED1) to non-pediatric hospitals (non-PED1) of children with low grade (I-II) and high grade (III-V) SOIs. RESULTS: In 2 years, 172 patients were treated for blunt SOI, with or without concomitant injuries. There were 48 (28%) low grade and 124 (72%) high grade SOIs. 33 (69%) patients were triaged with low grade SOI injuries at a non-PED1 center, and 17 (35%) were transferred to the PED1 hospital. Most had multiple injuries, but 7 (44%) were isolated, and none required a transfusion or any procedure/operation at either hospital. Of the 124 patients with high grade injuries, 41 (33%) primarily presented to the PED1 center, and 44 (35%) were transferred there. Of these, 2 required a splenectomy and none required angiography. 39 children were treated at non-PED1 centers without transfer, and 4 required splenectomy and 6 underwent angiography/embolization procedures. No patient with an isolated SOI died. CONCLUSIONS: Implementation of SOI guidelines across UPTN successfully allowed non-pediatric hospitals to safely admit children with low grade isolated SOI, keeping families closer to home, while standardizing pediatric triage for blunt abdominal trauma in the state. LEVEL OF EVIDENCE: III - Retrospective study.

A Pediatric Teletrauma Program Pilot Project: Improves Access to Pediatric Trauma Care and Timely Assessment of Pediatric Traumas.

BACKGROUND: Geographic location is a barrier to providing specialized care to pediatric traumas. In 2019, we instituted a pediatric teletrauma program in collaboration with the Statewide Pediatric Trauma Network at our level 1 pediatric trauma center (PTC). Triage guidelines were provided to partnering hospitals (PH) to aid in evaluation of pediatric traumas. Our pediatric trauma team was available for phone/video trauma consultation to provide recommendations on disposition and management. We hypothesized that this program would improve access and timely assessment of pediatric traumas while limiting patient transfers to our PTC. METHODS: A retrospective cohort study was conducted at the PTC between January 2019 to May 2023. All pediatric trauma patients age < 18 years who had teletrauma consults (TC) were included. We also evaluated all avoidable transfers without TC defined as admission for less than 36 hours without an intervention or imaging as a comparison group. RESULTS: A total of 151 TCs were identified: 62% male and median age of 8 years [IQR:4-12]. TC increased from 12 in 2019 to 100 in 2022-2023 and the number of partnering hospitals increased from 2 to 32. PH were 15-554 miles from the pediatric trauma center, with a median distance of 34 miles [IQR:28-119]. Following consultation, we recommended discharge 34%, admission 29%, or transfer to PTC 35%. Of those that were not transferred, 3% (3/97) required subsequent treatment at the PTC. Non-transferred TC had a higher percentage of TBI (61% vs 31%;p < 0.001) and were from farther, (40 miles[IQR:28-150] vs 30 miles[IQR:28-50];p < 0.001) compared to avoidable transferred patients without a TC. CONCLUSIONS: TC is a safe and viable addition to a pediatric trauma program faced with providing care to a large geographical catchment area. The pediatric teletrauma program provided management recommendations to 32 partnering hospitals and avoided transfer in approximately 63% of cases. LEVEL OF EVIDENCE: IV Treatment study.

Pediatric cervical spine clearance: A 10-year evaluation of multidetector computed tomography at a level 1 pediatric trauma center.

INTRODUCTION: Efficient and accurate evaluation of the pediatric cervical spine (c-spine) for both injury identification and posttraumatic clearance remains a challenge. We aimed to determine the sensitivity of multidetector computed tomography (MDCT) for identification of cervical spine injuries (CSIs) in pediatric blunt trauma patients. METHODS: A retrospective cohort study was conducted at a level 1 pediatric trauma center from 2012 to 2021. All pediatric trauma patients age younger than 18 years who underwent c-spine imaging (plain radiograph, MDCT, and/or magnetic resonance imaging [MRI]) were included. All patients with abnormal MRIs but normal MDCTs were reviewed by a pediatric spine surgeon to assess specific injury characteristics. RESULTS: A total of 4,477 patients underwent c-spine imaging, and 60 (1.3%) were diagnosed with a clinically significant CSI that required surgery or a halo. These patients were older, more likely to be intubated, have a Glasgow Coma Scale score of <14, and more likely to be transferred in from a referring hospital. One patient with a fracture on radiography and neurologic symptoms got an MRI and no MDCT before operative repair. All other patients who underwent surgery including halo placement for a clinically significant CSI had their injury diagnosed by MDCT, representing a sensitivity of 100%. There were 17 patients with abnormal MRIs and normal MDCTs; none underwent surgery or halo placement. Imaging from these patients was reviewed by a pediatric spine surgeon, and no unstable injuries were identified. CONCLUSION: Multidetector computed tomography appears to have 100% sensitivity for detecting clinically significant CSIs in pediatric trauma patients, regardless of age or mental status. Forthcoming prospective data will be useful to confirm these results and inform recommendations for whether pediatric c-spine clearance can be safely performed based on the results of a normal MDCT alone. LEVEL OF EVIDENCE: Diagnostic Tests or Criteria; Level IV.

The Utah Pediatric Trauma Network, a statewide pediatric trauma collaborative can safely help nonpediatric hospitals admit children with mild traumatic brain injury.

BACKGROUND: Created in 2019, the Utah Pediatric Trauma Network (UPTN) is a transparent noncompetitive collaboration of all hospitals in Utah with the purpose of improving pediatric trauma care. The UPTN implements evidence-based guidelines based on hospital resources and capabilities with quarterly review of data collected in a network-specific database. The first initiative was to help triage the care of traumatic brain injury (TBI) to prevent unnecessary transfers while ensuring appropriate care. The purpose of this study was to review the effectiveness of this network wide guideline. METHODS: The UPTN REDCap database was retrospectively reviewed between January 2019 and December 2021. Comparisons were made between the pediatric trauma center (PED1) and nonpediatric hospitals (non-PED1) in admissions of children with very mild, mild, or complicated mild TBI. RESULTS: Of the total 3,315 cases reviewed, 294 were admitted to a non-PED1 hospital and 1,061 to the PED1 hospital with very mild/mild/complicated mild TBI. Overall, kids treated at non-PED1 were older (mean, 14.9 vs. 7.7 years; p = 0.00001) and more likely to be 14 years or older (37% vs. 24%, p < 0.00001) compared with those at PED1. Increased admissions occurred post-UPTN at non-PED1 hospitals compared with pre-UPTN (43% vs. 14%, p < 0.00001). Children admitted to non-PED1 hospitals post-UPTN were younger (9.1 vs. 15.7 years, p = 0.002) with more kids younger than 14 years (67% vs. 38%, p = 0.014) compared with pre-UPTN. Two kids required next-day transfer to a higher-level center (1 to PED1), and none required surgery or neurosurgical evaluation. The mean length of stay was 21.8 hours (interquartile range, 11.9-25.4). Concomitantly, less children with very mild TBI were admitted to PED1 post-UPTN (6% vs. 27%, p < 0.00001) and more with complicated mild TBI (63% vs. 50%, p = 0.00003) than 2019. CONCLUSION: Implementation of TBI guidelines across the UPTN successfully allowed nonpediatric hospitals to safely admit children with very mild, mild, or complicated mild TBI. In addition, admitted kids were more like those treated at the PED1 hospital. LEVEL OF EVIDENCE: Prognostic/Epidemiological; Level IV.

Adolescent Vaping-Associated Trauma in the Western United States.

INTRODUCTION: Electronic cigarettes (e-cigarettes) are handheld, battery-powered vaporizing devices. It is estimated that more than 25% of youth have used these devices recreationally. While vaping-associated lung injury is an increasingly recognized risk, little is known about the risk of traumatic injuries associated with e-cigarette malfunction. METHODS: A multi-institutional retrospective study was performed by querying the electronic health records at nine children's hospitals. Patients who sustained traumatic injuries while vaping from January 2016 through December 2019 were identified. Patient demographics, injury characteristics, and the details of trauma management were reviewed. RESULTS: 15 children sustained traumatic injuries due to e-cigarette explosion. The median age was 17 y (range 13-18). The median injury severity score was 2 (range 1-5). Three patients reported that their injury coincided with their first vaping experience. Ten patients required hospital admission, three of whom required intensive care unit admission. Admitted patients had a median length of stay of 3 d (range 1-6). The injuries sustained were: facial burns (6), loss of multiple teeth (5), thigh and groin burns (5), hand burns (4), ocular burns (4), a radial nerve injury, a facial laceration, and a mandible fracture. Six children required operative intervention, one of whom required multiple operations for a severe hand injury. CONCLUSIONS: In addition to vaping-associated lung injury, vaping-associated traumatic injuries are an emerging and worrisome injury pattern sustained by adolescents in the United States. This report highlights another means by which e-cigarettes pose an increasing risk to a vulnerable youth population.

Sledding Accidents at a Level 1 Pediatric Trauma Center Between 2006 and 2016.

BACKGROUND: Sledding is not a risk-free winter sport. According to the US Consumer Product Safety Commission, there were an estimated 13,954 sledding accidents requiring medical care in 2010. However, specific information concerning pediatric injuries related to sledding is not well defined. OBJECTIVES: This study aimed to identify the most common types of injuries associated with sledding accidents and demographic factors related to risk of injury in pediatric patients, and to compare injuries associated with 2 different age groups and sexes. METHODS: This is a retrospective descriptive study of pediatric patients (<18 years of age) presenting to a regional level I pediatric trauma center secondary to a sledding injury between 2006 and 2016. Demographic information including sex, age, mechanism of injury, and injury severity score was captured and analyzed using descriptive statistics. RESULTS: There were 209 patients identified for 10 years. There were no mortalities. There were 85 patients with primary head injury, of which 82 (96.5%) were hospitalized and 33 (38.8%) required an intensive care unit (ICU) stay. Seventy-five patients primarily suffered from extremity injuries, of which 56 (74.6%) had lower extremity fractures requiring operative intervention. There was no difference in ICU or length of stay between younger children (0-11 years) and adolescents (12-18 years) or between male and female patients. CONCLUSIONS: Childhood sledding can result in a variety of significant injuries requiring surgical intervention and hospitalization. Children pulled on sleds behind motorized vehicles are at higher risk for more severe injuries resulting in a higher rate of ICU admission.

Operative repair in congenital diaphragmatic hernia: How long do we really need to wait?

OBJECTIVE: To analyze preoperative cardiopulmonary support and define preoperative stability relative to timing of surgical repair for CDH neonates not on ECMO. STUDY DESIGN: We retrospectively analyzed repeated measures of oxygenation index (OI; Paw*FiO2×100/PaO2) among 158 neonates for temporal preoperative trends. We defined physiologic stability using OI and characterized ventilator days and discharge age relative to delay in repair beyond physiologic stability. RESULTS: The OI in the first 24 h of life was temporally reliable and representative of the preoperative mean (ICC 0.70, 95% CI 0.61-0.77). A pre-operative OI of ≤ 9.4 (AUC 0.95) was predictive of survival. Surgical delay after an OI ≤ 9.4 resulted in increased ventilator days (1.4, 95% CI 1.1-1.9) and discharge age (1.5, 95% CI 1.2-2.0). When prospectively applied to a subsequent cohort, an OI ≤ 9.4 was again reflective of physiologic stability prior to repair. CONCLUSION: OI values are temporally reliable and change minimally after 24 h age. Delay in surgical repair of CDH beyond initial stability increases ventilator days and discharge age without a survival benefit. LEVEL OF EVIDENCE: Prognosis study, Level III.

Interest in Improving Access to Pediatric Trauma Care Through Telemedicine.

Despite improved outcomes at pediatric trauma centers (PTC), 90% of injured children are not treated at PTCs. Telemedicine may play a role in ensuring patients are transferred to the appropriate level of care. We aimed to determine the level of interest in trauma telemedicine with our PTC among referring facilities. A survey was conducted with the trauma program directors of 45 hospitals in Utah, which consisted of four multiple choice questions designed to determine interest in pediatric trauma telemedicine support, projected frequency of use, anticipated uses of telemedicine, and perceived barriers to implementation. Forty-one directors (91%) responded. 88% of directors were interested in developing a pediatric trauma telemedicine network. 20% estimated their center would use telemedicine more than once a week, 17% once a week, 24% once a month, and 37% a few times a year. The most frequently cited uses of a telemedicine program were triage/transfer decisions and provider support. Inadequate volume and insufficient funding were the most common perceived barriers. These data show there is a strong interest amongst hospitals in our state in pediatric trauma telemedicine. Inadequate volume to warrant a program and insufficient facility funding remain concerns for development of a program.

Congenital diaphragmatic hernia: a narrative review of controversies in neonatal management.

The consequences of most hernias can be immediately corrected by surgical repair. However, this isn't always the case for children born with a congenital diaphragmatic hernia. The derangements in physiology encountered immediately after birth result from pulmonary hypoplasia and hypertension caused by herniation of abdominal contents into the chest early in lung development. This degree of physiologic compromise can vary from mild to severe. Postnatal management of these children remains controversial. Although heavily studied, multi-institutional randomized controlled trials are lacking to help determine what constitutes best practice. Additionally, the results of the many studies currently within the literature that have investigated differing aspect of care (i.e., inhaled nitric oxide, ventilator type, timing of repair, role of extracorporeal membrane oxygenation, etc.) are difficult to interpret due to the small numbers investigated, the varying degree of physiologic compromise, and the contrasting care that exists between institutions. The aim of this paper is to review areas of controversy in the care of these complex kids, mainly: the use of fraction of inspired oxygen, surfactant therapy, gentle ventilation, mode of ventilation, medical management of pulmonary hypertension (inhaled nitric oxide, sildenafil, milrinone, bosentan, prostaglandins), the utilization of extracorporeal membrane oxygenation, and the timing of surgical repair.

Use of angioembolization in pediatric polytrauma patients: WITH BLUNT SPLENIC INJURYAngioembolization in Pediatric Blunt Splenic Injury.

BACKGROUND/PURPOSE: We sought to analyze the use of angioembolization (AE) after pediatric splenic injuries at adult and pediatric trauma centers (ATCs/PTCs). METHODS: The National Trauma Data Bank (2010-2015) was queried for patients (<18 years) who experienced blunt splenic trauma. Multivariate logistic regression was used to determine the association of AE with splenectomy. Propensity score matching was used to explore the relationship between trauma center designation and AE utilization. RESULTS: 14,027 encounters met inclusion criteria. 514 (3.7%) patients underwent AE. When compared to PTCs, patients were older, had a higher ISS, and more often presented in shock at ATCs (p<0.001 for all). Regression models demonstrated no difference in mortality between cohorts. Odds of splenectomy were lower for patients undergoing AE (OR 0.16 [CI: 0.08-0.31]), however this effect was mostly driven by utilization at ATCs. Using a 1:1 propensity score matching model, patients treated at ATCs were 4 times more likely to undergo AE and 7 times more likely to require a splenectomy compared to PTCs (p<0.001). Over 6 years, PTCs performed only 27 splenectomies and 23 AEs (1.1% and 0.9%, respectively). CONCLUSIONS: AE was associated with improved splenic salvage at ATCs in select patients but appeared overutilized when compared to outcomes at PTCs. PTCs accomplished a higher splenic salvage rate with a lower AE utilization. LEVEL OF EVIDENCE: III - Retrospective cohort study.

Early use of autologous blood patch pleurodesis in children is successful in resolving persistent air leaks.

PURPOSE: Experience with autologous blood patch (ABP) pleurodesis for persistent air leak in the pediatric population is limited. The purpose of this series was to describe the experience with ABP at a single tertiary children's hospital. METHODS: A retrospective study was performed of all thoracic procedures done by the pediatric surgery service over three years. RESULTS: Ten patients underwent a total of 17 ABPs. The median age of patients was 12 years (IQR 6-16). The most common underlying reasons for a thoracic procedure included: blebectomy for spontaneous pneumothorax (2), need for lung biopsy (2), resection of known malignant tumor (2), and empyema (2). The median number of days of persistent air leak before first ABP was 7.5 days (IQR 7-10). A second ABP was performed in 6 cases with a third procedure performed in one case. None of the patients developed respiratory compromise during ABP and no infectious complications were identified following ABP. CONCLUSIONS: Our cohort demonstrates that ABP for persistent air leak following thoracic surgery is effective with minimal morbidity in children. We believe ABP can be used early and in patients with a broad range of underlying lung pathology.

The "non-preventable" preventable transfer? An analysis of the care from support services that injured children transferred to a level 1 pediatric trauma center receive.

PURPOSE: Almost 30% of pediatric trauma transfers to our facility have previously been shown to be potentially preventable transfers (PT). However, we sought to evaluate what care from support services these PT received during admission. METHODS: Traumatically injured children transferred between January 2014 and June 2019 were retrospectively analyzed. A PT was defined as a child who was discharged within 36 h of arrival without surgical intervention or advanced imaging studies. PT that received support services were compared to those that did not to determine which patients may benefit from these services were their transfers prevented. RESULTS: There were 3212 transfers, and 927 (29%) were PT. When compared to non-PT, PT were younger, closer to our hospital, and had a lower ISS, extremity or C-spine injury, or assault/non-accidental trauma mechanism. PT were less likely to have a chest injury or a CT at the referring hospital. Of the PT, 30% had a support service consulted. PT with higher ISS or a head injury was more likely to receive a consultation with a support service. CONCLUSIONS: A significant proportion of these "preventable" transfers still receive important care from support services during their admission. TYPE OF STUDY: Retrospective study. LEVEL OF EVIDENCE: III.

Pediatric trauma telemedicine in a rural state: Lessons learned from a 1-year experience.

BACKGROUND: Previous research from our center has shown that 27% of the pediatric trauma transfers from referring facilities are potentially preventable. Our hospital is the only level 1 pediatric trauma center (PTC) in our state, and we are developing a pediatric trauma telehealth network to help keep certain injured children closer to home. We instituted a pediatric trauma telehealth program with a partnering community-based hospital in our state and aim to report our experience over the first year. METHODS: All pediatric trauma patients that presented to our partnering hospital from January 2019 to February 2020 were reviewed. Disposition was: a) telehealth consultation, b) admission to the children's unit without a telehealth consultation per our head trauma protocol, or c) transfer without telehealth consultation. Data on demographics, hospital course, and disposition were collected via chart review. RESULTS: Eight patients underwent telehealth consults and another 8 patients were admitted to the partnering hospital's children's unit based on the head trauma protocol without a telehealth consult. Patient's ages ranged from 7 months to 15 years. Of the patients that underwent telehealth consult, 7 presented with a head injury and 1 presented with a rib fracture/small pneumothorax. The patient with a pneumothorax was observed for 6 h and discharged home after a repeat chest x-ray was stable. All 15 patients with head injuries were observed and discharged from either the emergency department or children's unit after passing concussion testing. No patients required transfer to our PTC after observation, and none were readmitted. Fifty-six patients were transferred without telehealth consultation, and 3 of these patients could potentially have avoided transfer with a telehealth consultation. CONCLUSIONS: Telehealth in pediatric trauma can be a safe mechanism for preventing the transfer of patients that can be safely observed at a partnering hospital. From a facility that transfers an average of 30 trauma patients per year to our hospital, this program prevented 16 such transfers. Development of a head trauma protocol in collaboration with a pediatric neurosurgeon leads to an unexpected number of patients being admitted to the partnering hospital for observation without utilization of a telehealth consultation. TYPE OF STUDY: Retrospective study. LEVEL OF EVIDENCE: III.

Established Time Goals Can Increase the Efficiency of Trauma Resuscitation.

Introduction Our institution uses video review as a quality improvement tool. Starting in March 2018, we specifically focused on meeting certain time goals during trauma resuscitation aimed at decreasing time to final disposition. The purpose of this study was to evaluate the effect of establishing strict time goals on total time spent in the trauma bay by pediatric trauma patients. Materials and methods A retrospective review of all level I trauma activations at a level I pediatric trauma center between November 2017 and December 2018 was performed via manual review of the recorded trauma activations. Data on key time points such as time from arrival to transfer to gurney, to completion of primary survey, to chest x-ray, to Emergency Medical Services (EMS) report, to CT scan, and to disposition (CT or admission/operating room [OR] if no CT scan was performed) were analyzed and compared between the cohort of patients prior to implementation of the time goals with that after. The cohort of patients who presented between March 2018 and May 2018 were excluded to allow for time for the intervention to take effect. Results There were 13 level I trauma activations before implementation of the time goals and 41 after. There was a significant decrease in time to transfer to gurney (1.8 minutes vs. 1.0 minutes; p=0.02), to CT scan (18.8 minutes vs. 14.2 minutes; p=0.01), and to disposition (18.3 minutes vs. 14.9 minutes; p=0.047). There was no decrease in time to completion of primary survey, EMS report, or chest x-ray. Conclusions Utilizing video review in pediatric trauma as a quality improvement initiative with a focus on meeting specific time goals for key elements of the activation led to decreased total time in our trauma bay with critically ill patients.

Ball Magnets Clicked Together on the Epiglottis.

Neodymium ball magnets are commonly ingested by children and are a risk of causing significant morbidity if not addressed appropriately. While most ingested magnets are located distal to the epiglottis in the gastrointestinal tract, they can rarely get lodged across tissues in the mouth and throat such as the epiglottis. Though rare, this represents an impending airway emergency and requires urgent treatment once identified. We present the case of a two-year-old, asymptomatic male who presented after ingesting two neodymium ball magnets that were found to be clicked together across his epiglottis, which were ultimately retrieved by bronchoscopy without complications.

Defining the role of angioembolization in pediatric isolated blunt solid organ injury.

PURPOSE: To determine the incidence and outcomes of angiography in pediatric patients with blunt solid organ injury (SOI). METHODS: The National Trauma Data Bank (2010-2014) was queried for patients ≤19 years who experienced isolated blunt SOI. Multivariate logistic regression was used to evaluate characteristics associated with radiological and surgical intervention. RESULTS: Patients with isolated blunt injuries to the spleen (n = 7542), liver (n = 4549), and kidney (n = 2640) were identified. Use of angiography increased yearly from 1.6% to 3.1% of cases (p = 0.001) and was associated with older age (OR 2.61 [CI: 1.94-3.50], p < 0.001) and grade III or higher injury (OR 4.63 [CI: 3.11-6.90], p < 0.001). Odds of angiography were 4.9 times higher at adult trauma centers (TCs) than pediatric TCs overall, and almost 9 times higher for isolated splenic trauma (p < 0.001 for each). There was no improvement in splenic salvage after angiography for high grade injuries (3.5% vs. 4.8%, p = NS). Only 1.8% of cases began within 30 min of arrival (median time = 3.6 h). CONCLUSION: Variability exists in the utilization of angiography in pediatric blunt SOI between adult and pediatric TCs, with no improvement in splenic salvage. LEVEL OF EVIDENCE: Level III - Treatment study.

Validation of the "CHIIDA" and application for PICU triage in children with complicated mild traumatic brain injury.

BACKGROUND: The Children's Intracranial Injury Decision Aid (CHIIDA) was developed to predict which patients with complicated mild traumatic brain injury (cmTBI; GCS ≥13 with depressed skull fracture or intracranial injury) would achieve the composite outcome of neurosurgical intervention, intubation >24 h, or death. The study also explored the CHIIDA as a triage tool to determine need for PICU care. The purpose of this study is to externally validate the CHIIDA and assess its effects on PICU triage. METHODS: Retrospective cohort study (January 2016 to December 2017) to validate the CHIIDA to predict the composite outcome and assess its effects as a PICU triage tool at a level 1 pediatric trauma center. RESULTS: Of 345 patients with cmTBI, the composite outcome occurred in 16 patients (4.6%). At a cutoff score of 2, the CHIIDA predicted the composite outcome with a sensitivity of 94% (95% CI 67-99%) and specificity of 69% (95% CI 64-74%), similar to the original study. Using the same cutoff score for PICU triage resulted in 48 (71%) more patients admitted to PICU. CONCLUSIONS: In our cohort, the CHIIDA predicted the composite outcome well. If applied as a triage tool, it would have resulted in increased unnecessary PICU admissions. LEVEL OF EVIDENCE: Level III, prognosis.

Use of ECMO support in pediatric patients with severe thoracic trauma.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) has been used in the non-trauma setting for over 30 years. However, the use of ECMO in trauma remains a difficult question, as the risk of bleeding must be weighed against the benefits of cardiopulmonary support. METHODS: Retrospective review of children who sustained severe thoracic trauma (chest abbreviated injury score ≥3) and required ECMO support between 2009 and 2016. RESULTS: Of the 425 children who experienced severe thoracic trauma, 6 (1.4%) underwent ECMO support: 67% male, median age 4.8 years, median ISS 36, median GCS 3, and overall survival 83%. The median hospital day of ECMO initiation was 2 with a median ECMO duration of 7 days. All cannulations occurred through the right neck regardless of the size of the child. Five initially had veno-venous support with 1 requiring conversion to veno-arterial (VA) support. Both children on VA support suffered devastating cerebrovascular accidents, one of which ultimately led to withdrawal of care and death. Complications in the cohort included: paraplegia (1), neurocognitive defects/dysphonia (1), infected neck hematoma (1), deep femoral venous thrombosis (1), bilateral lower extremity spasticity (1). CONCLUSION: This small cohort supports the use of ECMO in children with severe thoracic injuries as a potentially lifesaving intervention, however, not without significant complication. LEVEL OF EVIDENCE: IV.

Comparison of early postnatal prediction models for survival in congenital diaphragmatic hernia.

OBJECTIVE: To compare the PF-PCO2 equation-partial pressure of arterial oxygen (PaO2)/fraction of inspired oxygen (FiO2) minus partial pressure of carbon dioxide (PCO2)-to three other tools for postnatal prediction of survival in infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: A retrospective analysis of 203 infants with CDH from 1 January 2003 to 30 June 2018. Area under the curve (AUC) analysis was performed for survival and secondary outcomes of survival without extracorporeal membrane oxygenation support (ECMO) and death despite ECMO. Predictive scores were calculated to determine cutoff for PF-PCO2 score. RESULTS: The PF-PCO2 tool had the highest AUC (0.84 for survival, 0.92 for survival without ECMO, and 0.83 for death despite ECMO). PF-PCO2 best predicted survival when >-60 and survival without ECMO when >+80. There was no optimal cutoff score for death despite ECMO. CONCLUSION: The PF-PCO2 tool best predicted postnatal survival in infants with CDH.
