Validation of the Subaxial Cervical Spine Injury Classification score in children: a single-institution experience at a level 1 pediatric trauma center.

OBJECTIVE: The Subaxial Cervical Spine Injury Classification (SLIC) score has not been previously validated for a pediatric population. The authors compared the SLIC treatment recommendations for pediatric subaxial cervical spine trauma with real-world pediatric spine surgery practice. METHODS: A retrospective cohort study at a pediatric level 1 trauma center was conducted in patients < 18 years of age evaluated for trauma from 2012 to 2021. An SLIC score was calculated for each patient, and the subsequent recommendations were compared with actual treatment delivered. Percentage misclassification, sensitivity, specificity, positive (PPV) and negative predictive value (NPV), and area under the receiver operating characteristic (ROC) curve (AUC) were calculated. RESULTS: Two hundred forty-three pediatric patients with trauma were included. Twenty-five patients (10.3%) underwent surgery and 218 were managed conservatively. The median SLIC score was 2 (interquartile range = 2). Sixteen patients (6.6%) had an SLIC score of 4, for which either conservative or surgical treatment is recommended; 27 children had an SLIC score ≥ 5, indicating a recommendation for surgical treatment; and 200 children had an SLIC score ≤ 3, indicating a recommendation for conservative treatment. Of the 243 patients, 227 received treatment consistent with SLIC score recommendations (p < 0.001). SLIC sensitivity in determining surgically treated patients was 79.2% and the specificity for accurately determining who underwent conservative treatment was 96.1%. The PPV was 70.3% and the NPV was 97.5%. There was a 5.7% misclassification rate (n = 13) using SLIC. Among patients for whom surgical treatment would be recommended by the SLIC, 29.6% (n = 8) did not undergo surgery; similarly, 2.5% (n = 5) of patients for whom conservative management would be recommended by the SLIC had surgery. The ROC curve for determining treatment received demonstrated excellent discriminative ability, with an AUC of 0.96 (OR 3.12, p < 0.001). Sensitivity decreased when the cohort was split by age (< 10 and ≥ 10 years old) to 0.5 and 0.82, respectively; specificity remained high at 0.98 and 0.94. CONCLUSIONS: The SLIC scoring system recommended similar treatment when compared with the actual treatment delivered for traumatic subaxial cervical spine injuries in children, with a low misclassification rate and a specificity of 96%. These findings demonstrate that the SLIC can be useful in guiding treatment for pediatric patients with subaxial cervical spine injuries. Further investigation into the score in young children (< 10 years) using a multicenter cohort is warranted.

Optimizing patient selection for ECMO after pediatric hypothermic cardiac arrest.

BACKGROUND: In 2004, our level 1 regional pediatric trauma center created a protocol to activate ECMO for children with suspected hypothermic cardiac arrest based on inclusion criteria: serum potassium ≤9, submersion <90 min, and core body temperature <30 °C. In 2017, Pasquier et al. developed a model to help predict the survival of adults after hypothermic cardiac arrest (HOPE score) that has not been validated in children. We sought to apply this score to our pediatric patient population to determine if it can optimize our patient selection. METHODS: This was a retrospective review of all patients cannulated onto VA ECMO for hypothermic cardiac arrest between 2004 and 2022. We used abstracted data points to calculate the HOPE score for our patient population, both with and without presumed asphyxia. RESULTS: Over 19 years, 18 patients were cannulated for suspected hypothermic arrest, with three survivors (17 %). The HOPE score survival prediction ranged from 1 to 86 % with presumed asphyxia and 6-98 % without presumed asphyxia. Survivor HOPE scores ranged from 9 to 86 % with presumed asphyxia and 42-98 % without presumed asphyxia. Non-survivors' scores ranged 1-29 % with asphyxia and 6-57 % without asphyxia. A cutoff of >5 % predicted survival with asphyxia for ECMO could have decreased our cannulations by half without missing survivors. CONCLUSION: ECMO can be a lifesaving measure for specific children after hypothermic arrest. However, identifying the patients that will benefit from this resource-intensive intervention remains difficult. HOPE score utilization may decrease the rate of futile cannulation in children, but multi-centered research is needed in the pediatric population.

Management and Outcomes of Pediatric Lymphatic Malformations: A Systematic Review From the APSA Outcomes and Evidence-Based Practice Committee.

BACKGROUND: Significant variation in management strategies for lymphatic malformations (LMs) in children persists. The goal of this systematic review is to summarize outcomes for medical therapy, sclerotherapy, and surgery, and to provide evidence-based recommendations regarding the treatment. METHODS: Three questions regarding LM management were generated according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Publicly available databases were queried to identify articles published from January 1, 1990, to December 31, 2021. A consensus statement of recommendations was generated in response to each question. RESULTS: The initial search identified 9326 abstracts, each reviewed by two authors. A total of 600 abstracts met selection criteria for full manuscript review with 202 subsequently utilized for extraction of data. Medical therapy, such as sirolimus, can be used as an adjunct with percutaneous treatments or surgery, or for extensive LM. Sclerotherapy can achieve partial or complete response in over 90% of patients and is most effective for macrocystic lesions. Depending on the size, extent, and location of the malformation, surgery can be considered. CONCLUSION: Evidence supporting best practices for the safety and effectiveness of management for LMs is currently of moderate quality. Many patients benefit from multi-modal treatment determined by the extent and type of LM. A multidisciplinary approach is recommended to determine the optimal individualized treatment for each patient.

Comparison of current to past outcomes in congenital diaphragmatic hernia using mri observed-to-expected total fetal lung volume.

BACKGROUND: Fetal Centers use imaging studies to predict congenital diaphragmatic hernia (CDH) prognosis and the need for fetal therapy. Given improving CDH survival, we hypothesized that current fetal imaging severity predictions no longer reflect true outcomes and fail to justify the risks of fetal therapy. METHODS: We analyzed our single-center contemporary data in a left-sided CDH cohort (n = 58) by prognostic criteria determined by MRI observed-to-expected total fetal lung volumes: severe <25%, moderate 25-35%, and mild >35%. We compared contemporary survival to prior studies and the TOTAL trials. RESULTS: Contemporary survival was significantly higher than past studies for all prognostic classifications (mild 100% vs 80-94%, moderate 95% vs 59-75%, severe 79% vs 13-25%; P < 0.01), and to either control or fetal therapy arms of the TOTAL trials. CONCLUSIONS: Current fetal imaging criteria are overly pessimistic and may lead to unwarranted fetal intervention. Fetal therapies remain experimental. Future studies will require updated prognostic criteria.

Two-Stage Liver Transplantation and Tricuspid Valve Replacement After Blunt Trauma in a Pediatric Patient.

In cases of uncontrollable hepatic hemorrhage or acute hepatic failure after trauma, liver transplantation can be a lifesaving procedure. Traumatic tricuspid valve injuries are rare, and symptoms can range from indolent to acute right heart failure. When concomitant, traumatic liver transplant and tricuspid injuries have significant physiologic interplay and management implications. We present a 14-year-old male injured in an all-terrain vehicle accident, who sustained a devastating disruption of the common bile duct and celiac artery injury, leading to acute hepatic failure, necessitating a two-stage liver transplantation. He was subsequently found to have a severe traumatic tricuspid injury, which required tricuspid valve replacement. At 4 years post-injury, he is without major complications. This is the first case presentation of the cooccurrence of these complex pathologies. Importantly, we demonstrate the complex decision-making surrounding traumatic liver transplantation and timing of subsequent tricuspid valve repair, weighing the complex interplay of these 2 pathologies.

The Sensitivity of Limited-Sequence MRI in Identifying Pediatric Cervical Spine Injury: A Western Pediatric Surgery Research Consortium Multicenter Retrospective Cohort Study.

INTRODUCTION: Clinical clearance of a child's cervical spine after trauma is often challenging due to impaired mental status or an unreliable neurologic examination. Magnetic resonance imaging (MRI) is the gold standard for excluding ligamentous injury in children but is constrained by long image acquisition times and frequent need for anesthesia. Limited-sequence MRI (LSMRI) is used in evaluating the evolution of traumatic brain injury and may also be useful for cervical spine clearance while potentially avoiding the need for anesthesia. The purpose of this study was to assess the sensitivity and negative predictive value of LSMRI as compared to gold standard full-sequence MRI as a screening tool to rule out clinically significant ligamentous cervical spine injury. METHODS: We conducted a ten-center, five-year retrospective cohort study (2017-2021) of all children (0-18y) with a cervical spine MRI after blunt trauma. MRI images were re-reviewed by a study pediatric radiologist at each site to determine if the presence of an injury could be identified on limited sequences alone. Unstable cervical spine injury was determined by study neurosurgeon review at each site. RESULTS: We identified 2,663 children less than 18 years of age who underwent an MRI of the cervical spine with 1,008 injuries detected on full-sequence studies. The sensitivity and negative predictive value of LSMRI were both >99% for detecting any injury and 100% for detecting any unstable injury. Young children (age < 5 years) were more likely to be electively intubated or sedated for cervical spine MRI. CONCLUSION: LSMRI is reliably detects clinically significant ligamentous injury in children after blunt trauma. To decrease anesthesia use and minimize MRI time, trauma centers should develop LSMRI screening protocols for children without a reliable neurologic exam.

Acute superior mesenteric artery syndrome complicated by severe gastric, pancreatic and renal ischaemia.

Superior mesenteric artery syndrome (SMAS) is a rare and potentially life-threatening cause of small bowel obstruction in which the superior mesenteric artery impinges on the third portion of the duodenum. SMAS is typically encountered in patients with low body fat and a history of rapid weight loss and is often diagnosed as a chronic or subacute condition. Here, we describe a case of a healthy adolescent boy without typical SMAS prodromal symptoms presenting with a severe, hyperacute proximal small bowel obstruction due to SMAS. Complications arising from massive gastric and duodenal distension, including gastric, pancreatic and renal ischaemia, necessitated emergent surgical intervention consisting of the duodenojejunostomy bypass with partial gastric resection. The patient recovered without significant lasting consequences.

Decision-Making in Pleural Drainage Following Lung Resection in Children: A Western Pediatric Surgery Research Consortium Survey.

INTRODUCTION: Studies of adults undergoing lung resection indicated that selective omission of pleural drains is safe and advantageous. Significant practice variation exists for pleural drainage practices for children undergoing lung resection. We surveyed pediatric surgeons in a 10-hospital research consortium to understand decision-making for placement of pleural drains following lung resection in children. METHODS: Faculty surgeons at the 10 member institutions of the Western Pediatric Surgery Research Consortium completed questionnaires using a REDCap survey platform. Descriptive statistics and bivariate analyses were used to characterize responses regarding indications and management of pleural drains following lung resection in pediatric patients. RESULTS: We received 96 responses from 109 surgeons (88 %). Most surgeons agreed that use of a pleural drain after lung resection contributes to post-operative pain, increases narcotic use, and prolongs hospitalization. Opinions varied around the immediate use of suction compared to water seal, and half routinely completed a water seal trial prior to drain removal. Surgeons who completed fellowship within the past 10 years left a pleural drain after wedge resection in 45 % of cases versus 78 % in those who completed fellowship more than 10 years ago (p = 0.001). The mean acceptable rate of unplanned post-operative pleural drain placement when pleural drainage was omitted at index operation was 6.3 % (±4.6 %). CONCLUSIONS: Most pediatric surgeons use pleural drainage following lung resection, with recent fellowship graduates more often omitting it. Future studies of pleural drain omission demonstrating low rates of unplanned postoperative pleural drain placement may motivate practice changes for children undergoing lung resection.

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.

Utility of Enteral Contrast Protocols in Pediatric Adhesive Small Bowel Obstruction: A Prospective Multicenter Observational Study.

OBJECTIVE: Our objective was to determine the utility of enteral contrast-based protocols in the diagnosis and management of adhesive small bowel obstruction (ASBO) for children. BACKGROUND: Enteral contrast-based protocols for adults with ASBO are associated with decreased need for surgery and shorter hospitalization. Pediatric-specific data are limited. METHODS: We conducted a prospective observational study between October 2020 and December 2022 at nine children's hospitals who are members of the Western Pediatric Surgery Research Consortium. Inclusion criteria were children aged 1-20 years diagnosed with ASBO who underwent a trial of nonoperative management (NOM) at hospital admission. Comparisons were made between those children who received an enteral contrast challenge and those who did not. The primary outcome was need for surgery. RESULTS: We enrolled 136 children (71% male; median age: 12 y); 84 (62%) received an enteral contrast challenge. There was no difference in rate of operative intervention between the no contrast (34.6%) and contrast groups (36.9%; P=0.93). Eighty-seven (64%) were successfully managed nonoperatively with no difference in median length of stay (P=0.10) or rate of unplanned readmission (P=0.14). Among the 49 children who required an operation, there was no significant difference in time from admission to surgery or rate of small bowel resection based on prior contrast administration. CONCLUSIONS: The addition of enteral contrast-based protocols for management of pediatric ASBO does not decrease the likelihood of surgery or shorten hospitalization. Larger randomized studies may be needed to further define the role of radiologic contrast in the management of ASBO in children.

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.

Cessation of Antibiotics for Complicated Appendicitis at Discharge Does Not Increase Risk of Post-operative Infection.

PURPOSE: The utilization of home antibiotic therapy following surgery for complicated pediatric appendicitis is highly variable. In 2019, we stopped home antibiotic therapy in this cohort at our institution. We sought to evaluate our outcomes following this protocol change. METHODS: We queried our institutional NSQIP Pediatrics data for all children undergoing appendectomy for complicated appendicitis between January 2015 and May 2022. We identified two cohorts: those discharged with home antibiotics (1/1/15-4/30/19) and those discharged with no home antibiotics (5/1/19-4/30/22). Both groups were treated with response based parenteral antibiotics while hospitalized and discharged when clinically well. Our primary outcome was postoperative deep organ space infection requiring intervention (drainage, aspiration, reoperation, or antibiotics). Secondary outcomes included length of stay, superficial site infection, Clostridium difficile colitis, ER visits, post-operative CT imaging, and readmission. RESULTS: There were 185 patients in the home antibiotic group (83% discharged with antibiotics) and 121 patients in the no home antibiotic group (8.3% discharged with antibiotics). There were no significant differences in deep organ space infection requiring intervention (7% vs. 7.4%, p = 1.0). Our length of stay was not different (4.5 days vs. 3.95 days, p = 0.32), nor were other secondary outcomes or patient characteristics. All patients had documented follow-up. CONCLUSIONS: We did not identify differences in deep organ space infections, length of stay or other events after eliminating home antibiotic therapy in our complicated appendicitis cohort. The use of home antibiotics following surgery for complicated appendicitis should be reconsidered. LEVEL OF EVIDENCE: III.

Outcomes of Extracorporeal Life Support Utilization for Pediatric Patients With COVID-19 Infections.

Outcomes of pediatric patients who received extracorporeal life support (ECLS) for COVID-19 remain poorly described. The aim of this multi-institutional retrospective observational study was to evaluate these outcomes and assess for prognostic factors associated with in-hospital mortality. Seventy-nine patients at 14 pediatric centers across the United States who received ECLS support for COVID-19 infections between January 2020 and July 2022 were included for analysis. Data were extracted from the electronic medical record. The median age was 14.5 years (interquartile range [IQR]: 2-17 years). Most patients were female (54.4%) and had at least one pre-existing comorbidity (84.8%), such as obesity (44.3%, median body mass index percentile: 97% [IQR: 67.5-99.0%]). Venovenous (VV) ECLS was initiated in 50.6% of patients. Median duration of ECLS was 12 days (IQR: 6.0-22.5 days) with a mean duration from admission to ECLS initiation of 5.2 ± 6.3 days. Survival to hospital discharge was 54.4%. Neurological deficits were reported in 16.3% of survivors. Nonsurvivors were of older age (13.3 ± 6.2 years vs. 9.3 ± 7.7 years, p = 0.012), more likely to receive renal replacement therapy (63.9% vs. 30.2%, p = 0.003), demonstrated longer durations from admission to ECLS initiation (7.0 ± 8.1 days vs. 3.7 ± 3.8 days, p = 0.030), and had higher rates of ECLS-related complications (91.7% vs. 69.8%, p = 0.016) than survivors. Pediatric patients with COVID-19 who received ECLS demonstrated substantial morbidity and further investigation is warranted to optimize management strategies.

Cervical Collar-Associated Pressure Injury in Pediatric Trauma Patients: A Western Pediatric Surgery Research Consortium Study.

BACKGROUND: Healthcare-associated pressure injuries (HAPI) are known to be associated with medical devices and are preventable. Cervical spine immobilization is commonly utilized in injured children prior to clinical clearance or for treatment of an unstable cervical spinal injury. The frequency of HAPI has been quantified in adults with cervical spine immobilization but has not been well-described in children. The aim of this study was to describe characteristics of children who developed HAPI associated with cervical immobilization. METHODS: We analyzed a retrospective cohort of children (0-18 years) who developed a stage two or greater cervical HAPI. This cohort was drawn from an overall sample of 49,218 registry patients treated over a five-year period (2017-2021) at ten pediatric trauma centers. Patient demographics, injury characteristics, and cervical immobilization were tabulated to describe the population. RESULTS: The cohort included 32 children with stage two or greater cervical HAPI. The median age was 5 years (IQR 2-13) and 78% (n = 25) were admitted to the intensive care unit. The median (IQR) time to diagnosis of HAPI was 11 (7-21) days post-injury. The majority of cervical HAPI (78%, 25/32) occurred in children requiring immobilization for cervical injuries, with only four children developing HAPI after wearing a prophylactic cervical collar in the absence of a cervical spine injury. CONCLUSION: Advanced-stage HAPI associated with cervical collar use in pediatric trauma patients is rare and usually occurs in patients with cervical spine injuries requiring immobilization for treatment. More expedient cervical spine clearance with MRI is unlikely to substantially reduce cervical HAPI in injured children. LEVEL OF EVIDENCE: Level III (Epidemiologic and Prognostic).

Pediatric surgical interventions on ECMO.

Extra Corporeal Membrane Oxygenation (ECMO) has historically been reserved for refractory pulmonary and cardiac support in children and adult. Operative intervention on ECMO was traditionally contraindicated due to hemorrhagic complications exacerbated by critical illness and anticoagulation needs. With advancements in ECMO circuitry and anticoagulation strategies operative procedures during ECMO have become feasible with minimal hemorrhagic risks. Here we review anticoagulation and operative intervention considerations in the pediatric population during ECMO cannulation. Pediatric surgical interventions currently described in the literature while on ECMO support include thoracotomy/thoracoscopy, tracheostomy, laparotomy, and injury related procedures i.e. wound debridement. A patient should not be precluded from a surgical intervention while on ECMO, if the surgery is indicated.

Machine learning to predict pediatric choledocholithiasis: A Western Pediatric Surgery Research Consortium retrospective study.

BACKGROUND: The purpose of this study was to accurately predict pediatric choledocholithiasis with clinical data using a computational machine learning algorithm. METHODS: A multicenter retrospective cohort study was performed on children <18 years of age who underwent cholecystectomy between 2016 to 2019 at 10 pediatric institutions. Demographic data, clinical findings, laboratory, and ultrasound results were evaluated by bivariate analyses. An Extra-Trees machine learning algorithm using k-fold cross-validation was used to determine predictive factors for choledocholithiasis. Model performance was assessed using the area under the receiver operating characteristic curve on a validation dataset. RESULTS: A cohort of 1,597 patients was included, with an average age of 13.9 ± 3.2 years. Choledocholithiasis was confirmed in 301 patients (18.8%). Obesity was the most common comorbidity in all patients. Choledocholithiasis was associated with the finding of a common bile duct stone on ultrasound, increased common bile duct diameter, and higher serum concentrations of aspartate aminotransferase, alanine transaminase, lipase, and direct and peak total bilirubin. Nine features (age, body mass index, common bile duct stone on ultrasound, common bile duct diameter, aspartate aminotransferase, alanine transaminase, lipase, direct bilirubin, and peak total bilirubin) were clinically important and included in the machine learning algorithm. Our 9-feature model deployed on new patients was found to be highly predictive for choledocholithiasis, with an area under the receiver operating characteristic score of 0.935. CONCLUSION: This multicenter study uses machine learning for pediatric choledocholithiasis. Nine clinical factors were highly predictive of choledocholithiasis, and a machine learning model trained using medical and laboratory data was able to identify children at the highest risk for choledocholithiasis.

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.

Hanging and Strangulation Injuries: An Institutional Review From a Level 1 Pediatric Trauma Center.

BACKGROUND: We sought to define the incidence and outcomes of pediatric hanging and strangulation injuries to inform best practices for trauma triage and management. METHODS: A retrospective review was conducted that included all patients who presented after hanging or strangulation to a Level I Pediatric Trauma Center from 2011 through 2021. Patient demographics, injury characteristics, and clinical outcomes were collected. All imaging modalities of the head and neck were reviewed to determine if a bony fracture or vascular injury was present. RESULTS: Over the 11-year study period, 128 patients met inclusion criteria. The median age of the cohort was 13 years [IQR: 8.5-15], most patients were male (60.9%), and the median GCS was 11 [3, 15]. There were 96 cases (75%) that were intentional injuries. 76 patients (59.4%) received imaging in the form of plain radiographs, CT, or MRI of the neck and cervical spine. No fractures were identified and there were 0 clinically significant cervical spine injuries. CT angiograms of the neck identified no cerebral vascular injuries. Mortality was high (32%), and 25% of patients with nonaccidental injuries had a documented prior suicide attempt. CONCLUSION: We identified no cervical spine fractures and no blunt cerebral vascular injuries after a hanging or strangulation in over 10 years at a Level 1 Pediatric Trauma Center. Use of CT and CT angiography of the neck and cervical spine should be minimized in this patient population without high clinical index of suspicion and/or significant mechanism. LEVEL OF EVIDENCE: 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.
