Delphi Process for Validation of Fluid Treatment Algorithm for Critically Ill Pediatric Trauma Patients.

INTRODUCTION: While intravenous fluid therapy is essential to re-establishing volume status in children who have experienced trauma, aggressive resuscitation can lead to various complications. There remains a lack of consensus on whether pediatric trauma patients will benefit from a liberal or restrictive crystalloid resuscitation approach and how to optimally identify and transition between fluid phases. METHODS: A panel was comprised of physicians with expertise in pediatric trauma, critical care, and emergency medicine. A three-round Delphi process was conducted via an online survey, with each round being followed by a live video conference. Experts agreed or disagreed with each aspect of the proposed fluid management algorithm on a five-level Likert scale. The group opinion level defined an algorithm parameter's acceptance or rejection with greater than 75% agreement resulting in acceptance and greater than 50% disagreement resulting in rejection. The remaining were discussed and re-presented in the next round. RESULTS: Fourteen experts from five Level 1 pediatric trauma centers representing three subspecialties were included. Responses were received from 13/14 participants (93%). In round 1, 64% of the parameters were accepted, while the remaining 36% were discussed and re-presented. In round 2, 90% of the parameters were accepted. Following round 3, there was 100% acceptance by all the experts on the revised and final version of the algorithm. CONCLUSIONS: We present a validated algorithm for intavenous fluid management in pediatric trauma patients that focuses on the de-escalation of fluids. Focusing on this time point of fluid therapy will help minimize iatrogenic complications of crystalloid fluids within this patient population.

Impact of insertion site on complications in central venous access devices.

PURPOSE: There is still debate over the safest route for the placement of long-term central venous access devices. The aim of this study was to review a large, single-institution experience to determine the impact of access location on peri-operative complications. METHODS: The records of patients undergoing subcutaneous port (SQP) and tunneled catheter insertion over a seven-year period were reviewed. Vein cannulated (subclavian (SCV) versus internal jugular (IJ) vein), and 30-day complications were assessed. Surgical complications included pneumothorax, hemothorax, infections, arrhythmia or malpositioning requiring intervention. RESULTS: A total of 1,309 patients were included (618 SQP, 691 tunneled catheters). The location for insertion was SCV (909, 69.4%) and IJ (400, 30.6%). There were 69 complications (5.2%) (41, 4.5% SCV, 28, 7.0% IJV) including: malpositioning/malfunctioning (SCV 13, 1.4% and IJV 14, 3.0%), pneumothorax (SCV 4, 0.4% and IJV 1, 0.3%), hemothorax (SCV 0 and IJV 1, 0.3%), arrhythmia (SCV 1, 0.1%, and IJV 0), and infection within 30 days of placement (SCV 20, 2.2% and IJ 11, 2.8%). The complication rates were not significantly different based on site (p = 0.080). CONCLUSION: There was no significant difference in complication rates when using the subclavian versus the internal jugular vein as the site for long-term central venous access. LEVEL OF EVIDENCE: III, retrospective comparative study.

Pediatric Spontaneous Pneumothorax: Does Initial Treatment Affect Outcomes?

BACKGROUND: Primary spontaneous pneumothorax (PSP) commonly occurs in adolescents, most commonly in males, and has recurrence rates between 20% and 60%. Surgical therapy has long been debated regarding its role in preventing recurrence, with no current consensus on guidelines for care. The purpose of this study is to examine the effect of treatment type on recurrence rates in pediatric PSP. METHODS: This is a single-institution, institutional review board-approved retrospective analysis of patients aged 1 to 18 diagnosed with their first occurrence of PSP between 2009 and 2017. Patient demographics, hospital course, and outcomes over a 2-y period were collected. Patients were divided into nonoperative (oxygen therapy only) management, chest tube placement, and surgical management. The primary outcome was the recurrence rate. RESULTS: Sixty-four patients diagnosed with PSP met inclusive criteria. The mean age was 15.5, and 48 (75%) of patients were men. Twenty-one patients (33%) underwent nonoperative treatment, 24 patients (37.5%) underwent operative treatment with video-assisted thoracoscopic surgery or open thoracotomy, and 19 patients (30%) underwent chest tube or pigtail placement alone. Fifteen patients (23.4%) experienced a recurrence within 2 y: 6 patients (29%) from the nonoperative treatment group, 4 (21%) who were treated with the chest tube only, and 5 (21%) who underwent video-assisted thoracoscopic surgery or open thoracotomy. No statistically significant difference in recurrence rates was found between treatment groups. Pneumothorax size was found to differ between treatment type; larger pneumothoraces were more likely to undergo surgical intervention (P = 0.0003). Smaller pneumothoraces were associated with higher rates of recurrence on multivariate logistic regression analysis (P = 0.046). CONCLUSIONS: Recurrence of PSP in adolescents was found to be 23.4% after 2-y follow-up. Smaller-sized pneumothoraces were associated with higher rates of recurrence, but treatment type did not significantly affect recurrence rates.

A Multicenter Study of Nutritional Adequacy in Neonatal and Pediatric Extracorporeal Life Support.

BACKGROUND: Malnutrition in critically ill patients is common in neonates and children, including those that receive extracorporeal life support (ECLS). We hypothesize that nutritional adequacy is highly variable, overall nutritional adequacy is poor, and enteral nutrition is underutilized in this population. MATERIALS AND METHODS: A retrospective study of neonates and children (age<18 y) receiving ECLS at 5 centers from 2012 to 2014 was performed. Demographic, clinical, and outcome data were analyzed. Continuous variables are presented as median [IQR]. Adequate nutrition was defined as meeting 66% of daily caloric goals during ECLS support. RESULTS: Two hundred and eighty three patients received ECLS; the median age was 12 d [3 d, 16.4 y] and 47% were male. ECLS categories were neonatal pulmonary 33.9%, neonatal cardiac 25.1%, pediatric pulmonary 17.7%, and pediatric cardiac 23.3%. The predominant mode was venoarterial (70%). Mortality was 41%. Pre-ECLS enteral and parenteral nutrition was present in 80% and 71.5% of patients, respectively. The median percentage days of adequate caloric and protein nutrition were 50% [0, 78] and 67% [22, 86], respectively. The median percentage days with adequate caloric and protein nutrition by the enteral route alone was 22% [0, 65] and 0 [0, 50], respectively. Gastrointestinal complications occurred in 19.7% of patients including hemorrhage (4.2%), enterocolitis (2.5%), intra-abdominal hypertension or compartment syndrome (0.7%), and perforation (0.4%). CONCLUSIONS: Although nutritional delivery during ECLS is adequate, the use of enteral nutrition is low despite relatively infrequent observed gastrointestinal complications.

Mediastinal Lymphadenopathy in Children With Histoplasmosis.

BACKGROUND: Mediastinal lymphadenopathy (ML) in children can arise from malignancy, infection, or rheumatic illness among others, and may be found incidentally on imaging or during workup for a variety of symptoms. Our aim was to describe the clinical presentation and natural history of histoplasmosis in children who present to a tertiary care center with ML in an endemic area of the country. METHODS: After institutional review board approval, a retrospective study of all children (aged < 21 y) presenting with proven (positive serologies) or suspected histoplasmosis (negative serologies, negative tuberculosis testing, and benign outcomes in follow-up) over a 5-y period was done. Seventy-four patients were tested; those with another diagnosis (n = 6) or without ML (n = 26) were excluded, for a total cohort of 44 patients. Demographics, clinical presentation, symptoms, laboratory data, treatment course, radiography studies, and inpatient and outpatient visits were examined. RESULTS: Of the 44 patients with ML, 27 had proven histoplasmosis, and 19 had suspected histoplasmosis. The median follow-up by imaging or clinical examination was 6.9 mo (0.3-73.2 mo). Sixteen patients received antifungal therapy with itraconazole, and 15 patients received at least one course of steroids, nearly all for respiratory symptoms; 11 patients (24%) received both. There was no difference in readmission rate (n = 5 versus 2, P = 0.7) or recurrence of symptoms (n = 2 versus 5, P = 0.4) between patients who received an antifungal and those that did not. Receiving steroid therapy was associated with airway narrowing and a higher readmission rate (n =6 versus 2 who were not treated with steroids, P = 0.04), but not with symptom recurrence. Nine lymph node or mass biopsies were performed; however, the pathology only confirmed nonspecific infection in three and was nondiagnostic in the remaining six patients. Twenty-seven patients had at least one confirmatory laboratory test positive for histoplasmosis. Thirty-nine of the 44 patients (84%) with a diagnosis of histoplasmosis (proven or suspected) were asymptomatic by 1-2 mo follow up, with the remainder having intermittent chest pain or reactive airway disease. CONCLUSIONS: ML because of proven or suspected histoplasmosis is usually a self-limiting disease that can be managed with treatment of the child's symptoms. Antifungals and steroids are of unclear benefit and may not alter the natural course of the disease. Biopsies are rarely diagnostic in the setting of ML, and invasive procedures should be avoided.

In-hospital Pediatric Endoscopic Retrograde Cholangiopancreatography Is Associated With Shorter Hospitalization for Children With Choledocholithiasis.

OBJECTIVES: Children with choledocholithiasis are frequently managed at tertiary children's hospitals that do not have available endoscopic retrograde cholangiopancreatography (ERCP) proceduralists. We hypothesized that patients treated at hospitals without ERCP proceduralists would have a longer hospital length of stay (LOS) than those with ERCP proceduralists. METHODS: Charts were reviewed for patients who underwent cholecystectomy and ERCP at 3 tertiary children's hospitals over 10 years. Trauma and complicated pancreatitis patients were excluded. Comparisons between patients requiring and not requiring transfer for ERCP were made using Wilcoxon rank-sum tests for continuous variables and Fisher's exact tests for categorical variables. RESULTS: One hundred and sixty-four children underwent ERCP for suspected choledocholithiasis: 79 (48%) in the transfer group and 85 (52%) in the no transfer group.Median LOS was longer for patients requiring transfer (7 vs 5 days, P < 0.0001). One-third (34%) of the transfer patients had magnetic resonance cholangiopancreatography compared to only 7% that did not require transfer (P < 0.0001). Among the 123 patients who underwent ERCP before cholecystectomy, 53% required (66/123) transfer and 47% (57/123) did not. Transfer group patients had longer median hospital LOS (P < 0.0001), more days between admission and ERCP (P < 0.0001), and more days between ERCP and surgery (P = 0.0004). CONCLUSIONS: Overall median LOS was significantly shorter for patients who underwent ERCP at the admitting facility. Patients who underwent ERCP before cholecystectomy at hospitals without available ERCP proceduralists incurred longer LOS. There is a need for more pediatric proceduralists appropriately trained to perform ERCP in children.

Variability in the evalution of pediatric blunt abdominal trauma.

PURPOSE: To describe the practice pattern for routine laboratory and imaging assessment of children following blunt abdominal trauma (BAT). METHODS: Children (age < 16 years) presenting to 14 pediatric trauma centers following BAT over a 1-year period were prospectively identified. Injury, demographic, routine laboratory and imaging utilization data were collected. Descriptive, comparative, and correlation analysis was performed. RESULTS: 2188 children with a median age of 8 (4,12) years were included and the median injury severity score was 5 (1,10). There were significant differences in activation status, injury severity, and mechanism across centers; however, there was no correlation of level of activation, injury severity, or severe mechanism with test utilization. Routine laboratory and imaging utilization for hematocrit, hepatic enzymes, pancreatic enzymes, base deficit urine microscopy, chest and pelvis X-ray, and abdominal computed tomography (CT) varied significantly among centers. Only obtaining a hematocrit had a moderate correlation with CT use. There was no correlation between centers that were high or low frequency laboratory utilizers with CT use. CONCLUSIONS: Wide variability exists in the routine initial laboratory and imaging assessment in children following BAT. This represents an opportunity for quality improvement in pediatric trauma. LEVEL OF EVIDENCE: Level II.

The utility of presacral drainage in penetrating rectal injuries in adult and pediatric patients.

BACKGROUND: With changing weaponry associated with injuries in civilian trauma, there is no clinical census on the utility of presacral drainage (PSD) in penetrating rectal injuries (PRIs), particularly in pediatric patients. METHODS: Patients with PRI from July 2004-June 2014 treated at two free-standing children's hospitals and two adult level 1 trauma centers were compared by age (pediatric patients ≤16 years) and PSD. A stratified analysis was performed based on age. The primary outcome was pelvic/presacral abscess. RESULTS: We identified 81 patients with PRI; 19 pediatric, 62 adult. Forty patients had PSD; only three pediatric patients had a drain. Adult patients were more likely to have sustained gunshot wounds (84%), whereas pediatric patients were more likely to sustain impalement injuries (59%). Pediatric patients were more likely to have distal extraperitoneal injuries (56% versus 27% in adults, P = 0.03). PSD was more common in adult patients (59% versus 14%, P = 0.0004), African-Americans (71% versus 11% Caucasian, P < 0.01), and those sustaining gun shot wounds (63% versus 18% impalement, P < 0.01); only race remained significant in stratified analysis for both adult and pediatric patients. There were three cases of pelvic/presacral abscess, all in the adult patients (P = 0.31); one patient with PSD and two without PSD (P = 0.58). In stratified analysis, there were no differences in any infectious complication between those with and without PSD. CONCLUSIONS: Pelvic/presacral abscess is a rare complication of PRI, especially in pediatric patients. PSD is not associated with decreased rates of infectious complications and may not be necessary in the treatment of PRI.

Treatment of congenital pulmonary airway malformations: a systematic review from the APSA outcomes and evidence based practice committee.

PURPOSE: Variation in management characterizes treatment of infants with a congenital pulmonary airway malformation (CPAM). This review addresses six clinically applicable questions using available evidence to provide recommendations for the treatment of these patients. METHODS: Questions regarding the management of a pediatric patient with a CPAM were generated. English language articles published between 1960 and 2014 were compiled after searching Medline and OvidSP. The articles were divided by subject area and by the question asked, then reviewed and included if they specifically addressed the proposed question. RESULTS: 1040 articles were identified on initial search. After screening abstracts per eligibility criteria, 130 articles were used to answer the proposed questions. Based on the available literature, resection of an asymptomatic CPAM is controversial, and when performed is usually completed within the first six months of life. Lobectomy remains the standard resection method for CPAM, and can be performed thoracoscopically or via thoracotomy. There is no consensus regarding a monitoring protocol for observing asymptomatic lesions, although at least one chest computerized tomogram (CT) should be performed postnatally for lesion characterization. An antenatally identified CPAM can be evaluated with MRI if fetal intervention is being considered, but is not required for the fetus with a lesion not at risk for hydrops. Prenatal consultation should be offered for infants with CPAM and encouraged for those infants in whom characteristics indicate risk of hydrops. CONCLUSIONS: Very few articles provided definitive recommendations for care of the patient with a CPAM and none reported Level I or II evidence. Based on available information, CPAMs are usually resected early in life if at all. A prenatally diagnosed congenital lung lesion should be evaluated postnatally with CT, and prenatal counseling should be undertaken in patients at risk for hydrops.

Management of Pediatric Solid Organ Injuries.

Solid organ injury (SOI) is common in children who experience abdominal trauma, and the management of such injuries has evolved significantly over the past several decades. In 2000, the American Pediatric Surgical Association (APSA) published the first societal guidelines for the management of blunt spleen and/or liver injury (BLSI), advocating for optimized resource utilization while maintaining patient safety. Nonoperative management (NOM) has become the mainstay of treatment for SOI, and since the publication of the APSA guidelines, numerous groups have evaluated how invasive procedures, hospitalization, and activity restrictions may be safely minimized in children with SOI. Here, we review the current evidence-based management guidelines in place for the treatment of injuries to the spleen, liver, kidney, and pancreas in children, including initial evaluation, inpatient management, and long-term care, as well as gaps that exist in the current literature that may be targeted for further optimization of protocols for pediatric SOI.

Pediatric Firearm Trauma on the Rise: A Retrospective Review of Over 1,100 Cases in 12 Years at One Center.

BACKGROUND: Gunshot injuries are the leading cause of death among children in the United States. The goal of this study was to better understand if certain age groups, mechanisms of injury, and type of firearms were associated with the increasing rates of pediatric gun-related trauma. We hypothesized that the extremities were disproportionately targeted when compared with the random likelihood of striking specific body-surface areas. METHODS: This study includes pediatric firearm-related injury (FRI) patients who presented to a single free-standing level 1 pediatric hospital or died at the scene from 2010 to 2021. The hospital data was collected prospectively as part of a level 1 trauma system electronic database. Death data was collected from the local coroner's office. RESULTS: Between 2010 and 2021, 1,126 pediatric FRI occurred in the geographic region studied. Demographic information available for 1,118 patients showed that 897 (80.23%) were male, and that black individuals had a statistically significant increased rate of FRI compared with white or Hispanic individuals. Mean age was 13.69 years. Most injuries were caused by handguns. CONCLUSIONS: This data could help leaders design strategies to combat the violence, such as legislation that limits handgun access to all, especially children, and mandates safe storage of handguns. Gun-lock programs, universal background checks, and firearm-ownership education also might help stem this tide of violence. LEVEL OF EVIDENCE: Level II Prognosis study.

Prevalence and outcomes of high versus low ratio plasma to red blood cell resuscitation in a multi-institutional cohort of severely injured children.

BACKGROUND: The benefit of targeting high ratio fresh frozen plasma (FFP)/red blood cell (RBC) transfusion in pediatric trauma resuscitation is unclear as existing studies are limited to patients who retrospectively met criteria for massive transfusion. The purpose of this study is to evaluate the use of high ratio FFP/RBC transfusion and the association with outcomes in children presenting in shock. METHODS: A post hoc analysis of a 24-institution prospective observational study (April 2018 to September 2019) of injured children younger than 18 years with elevated age-adjusted shock index was performed. Patients transfused within 24 hours were stratified into cohorts of low (<1:2) or high (≥1:2) ratio FFP/RBC. Nonparametric Kruskal-Wallis and χ 2 were used to compare characteristics and mortality. Competing risks analysis was used to compare extended (≥75th percentile) ventilator, intensive care, and hospital days while accounting for early deaths. RESULTS: Of 135 children with median (interquartile range) age 10 (5-14) years and weight 40 (20-64) kg, 85 (63%) received low ratio transfusion and 50 (37%) high ratio despite similar activation of institutional massive transfusion protocols (low-38%, high-46%, p = 0.34). Most patients sustained blunt injuries (70%). Median injury severity score was greater in high ratio patients (low-25, high-33, p = 0.01); however, hospital mortality was similar (low-24%, high-20%, p = 0.65) as was the risk of extended ventilator, intensive care unit, and hospital days (all p > 0.05). CONCLUSION: Despite increased injury severity, patients who received a high ratio of FFP/RBC had comparable rates of mortality. These data suggest high ratio FFP/RBC resuscitation is not associated with worst outcomes in children who present in shock. Massive transfusion protocol activation was not associated with receipt of high ratio transfusion, suggesting variability in MTP between centers.

A dedicated automated injection system for dynamic contrast-enhanced MRI experiments in mice.

PURPOSE: To develop a reproducible small-animal dynamic contrast-enhanced (DCE) MRI set-up for mice through which volumes <100 µL can be accurately and safely injected and to test this set-up by means of DCE measurements in resting muscle and tumor tissue. MATERIALS AND METHODS: The contrast agent (CA) injection system comprised 2 MR-compatible syringe pumps placed 50 cm from the 7T magnet bore where the fringe field is approximately 40 mT. Microbore tubing and T-connector, close to the injection site, minimized dead volume (<10 µL). For DCE-MRI measurements in 8 CB-17 SCID mice with 1500-2500 mm(3) large orthotopic neuroblastoma, a bolus of 10-fold-diluted Gd-DTPA CA solution (0.1 mmol/kg) was delivered (5 µL/s), followed by a 50-µL saline flush. Retro-orbital injections were given instead of tail vein injections, because the peripheral vasculature was reduced because of large tumor burden. RESULTS: The CA injection was successful in 19 of 24 experiments. Optical assessment showed minimal dispersion of ink-colored CA bolus. Mean (± SD) pharmacokinetic parameters retrieved from DCE-MRI examinations in resting muscle (K(trans) = 0.038 ± 0.025 min(-1), k(ep) = 0.66 ± 0.48 min(-1), v(e) = 0.060 ± 0.014, v(p) = 0.033 ± 0.021) and tumor (K(trans) = 0.082 ± 0.071 min(-1), k(ep) = 0.82 ± 0.80 min(-1), v(e) = 0.121 ± 0.075, v(p) = 0.093 ± 0.051) agreed with those reported previously. CONCLUSION: We successfully designed and implemented a DCE-MRI set-up system with short injection lines and low dead volume. The system can be used at any field strength with the syringe pumps placed at a sufficiently low fringe field (<40 mT).

Utility of continuous pulse CO-oximetry for hemoglobin monitoring in pediatric patients with solid organ injuries at level 1 trauma centers: A pilot study.

INTRODUCTION: Hemorrhage is a major cause of preventable death in injured children. Monitoring after admission often requires multiple blood draws, which have been shown to be stressful in pediatric patients. The Rainbow-7 device is a continuous pulse CO-oximeter that measures multiple wavelengths of light, permitting continuous estimation of the total hemoglobin (Hb) level. The purpose of this study was to evaluate the utility of the noninvasive Hb measurement for monitoring pediatric trauma patients admitted with solid organ injury. METHODS: This is a prospective, dual-center, observational trial for patients younger than age 18 years admitted to a Level I pediatric trauma center. Following admission, blood was routinely measured as per current solid organ injury protocols. Noninvasive Hb monitoring was initiated after admission. Time-synced data for Hb levels were compared with that taken using blood draws. Data were evaluated using bivariate correlation, linear regression, and Bland-Altman analysis. RESULTS: Over a 1-year period, 39 patients were enrolled. The mean ± SD age was 11 ± 3.8 years. Forty-six percent (n = 18) of patients were male. The mean ± SD Injury Severity Score was 19 ± 13. The average change in Hb levels between laboratory measurements was -0.34 ± 0.95 g/dL, and the average change in noninvasive Hb was -0.12 ± 1.0 g/dL per measurement. Noninvasive Hb values were significantly correlated with laboratory measurements ( p < 0.001). Trends in laboratory Hb measurements were highly correlated with changes in noninvasive levels ( p < 0.001). Bland-Altman analysis demonstrated similar deviation from the mean throughout the range of Hb values, but the differences between measurements were increased by anemia, African American race, and elevated shock index, pediatric age-adjusted score and Injury Severity Score. CONCLUSION: Noninvasive Hb values demonstrated correlation with measured Hb concentration as isolated measurements and trends, although results were affected by skin pigmentation, shock, and injury severity. Given the rapid availability of results and the lack of requirement of venipuncture, noninvasive Hb monitoring may be a valuable adjunct for pediatric solid organ injury protocols. Further study is required to determine its role in management. LEVEL OF EVIDENCE: Dianostic Test or Criteria; Level III.

Updated APSA Guidelines for the Management of Blunt Liver and Spleen Injuries.

BACKGROUND: Non-operative management of blunt liver and spleen injuries was championed initially in children with the first management guideline published in 2000 by the American Pediatric Surgical Association (APSA). Multiple articles have expanded on the original guidelines and additional therapy has been investigated to improve care for these patients. Based on a literature review and current consensus, the management guidelines for the treatment of blunt liver and spleen injuries are presented. METHODS: A recent literature review by the APSA Outcomes committee [2] was utilized as the basis for the guideline recommendations. A task force was assembled from the APSA Committee on Trauma to review the original guidelines, the literature reported by the Outcomes Committee and then to develop an easy to implement guideline. RESULTS: The updated guidelines for the management of blunt liver and spleen injuries are divided into 4 sections: Admission, Procedures, Set Free and Aftercare. Admission to the intensive care unit is based on abnormal vital signs after resuscitation with stable patients admitted to the ward with minimal restrictions. Procedure recommendations include transfusions for low hemoglobin (<7 mg/dL) or signs of ongoing bleeding. Angioembolization and operative exploration is limited to those patients with clinical signs of continued bleeding after resuscitation. Discharge is based on clinical condition and not grade of injury. Activity restrictions remain the same while follow-up imaging is only indicated for symptomatic patients. CONCLUSION: The updated APSA guidelines for the management of blunt liver and spleen injuries present an easy-to-follow management strategy for children. LEVEL OF EVIDENCE: Level 5.

Crystalloid volume is associated with short-term morbidity in children with severe traumatic brain injury: An Eastern Association for the Surgery of Trauma multicenter trial post hoc analysis.

OBJECTIVE: This study examined differences in clinical and resuscitation characteristics between injured children with and without severe traumatic brain injury (sTBI) and aimed to identify resuscitation characteristics associated with improved outcomes following sTBI. METHODS: This is a post hoc analysis of a prospective observational study of injured children younger than 18 years (2018-2019) transported from the scene, with elevated shock index pediatric-adjusted on arrival and head Abbreviated Injury Scale score of ≥3. Timing and volume of resuscitation products were assessed using χ 2t test, Fisher's exact t test, Kruskal-Wallis, and multivariable logistic regression analyses. RESULTS: There were 142 patients with sTBI and 547 with non-sTBI injuries. Severe traumatic brain injury patients had lower initial hemoglobin (11.3 vs. 12.4, p < 0.001), greater initial international normalized ratio (1.4 vs. 1.1, p < 0.001), greater Injury Severity Score (25 vs. 5, p < 0.001), greater rates of ventilator (59% vs. 11%, p < 0.001) and intensive care unit (ICU) requirement (79% vs. 27%, p < 0.001), and more inpatient complications (18% vs. 3.3%, p < 0.001). Severe traumatic brain injury patients received more prehospital crystalloid (25% vs. 15%, p = 0.008), ≥1 crystalloid boluses (52% vs. 24%, p < 0.001), and blood transfusion (44% vs. 12%, p < 0.001) than non-sTBI patients. Among sTBI patients, receipt of ≥1 crystalloid bolus (n = 75) was associated with greater ICU need (92% vs. 64%, p < 0.001), longer median ICU (6 vs. 4 days, p = 0.027) and hospital stay (9 vs. 4 days, p < 0.001), and more in-hospital complications (31% vs. 7.5%, p = 0.003) than those who received <1 bolus (n = 67). These findings persisted after adjustment for Injury Severity Score (odds ratio, 3.4-4.4; all p < 0.010). CONCLUSION: Pediatric trauma patients with sTBI received more crystalloid than those without sTBI despite having a greater international normalized ratio at presentation and more frequently requiring blood products. Excessive crystalloid may be associated with worsened outcomes, including in-hospital mortality, seen among pediatric sTBI patients who received ≥1 crystalloid bolus. Further attention to a crystalloid sparing, early transfusion approach to resuscitation of children with sTBI is needed. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Ultrasound is safe and highly specific for confirmation of proper gastrostomy tube replacement in pediatric patients.

BACKGROUND: Gastrostomy tube (GT) dislodgement is a common cause of Pediatric Emergency Department (PED) visits. Postoperative patients and those who require stoma dilation are more likely to have complications during emergent replacement. Although incorrect replacement can cause significant morbidity overall, the occurrence is infrequent. Contrast injection of the GT is considered the standard for confirming proper placement. Case reports in both pediatric and adult patients suggest that ultrasound can be used to confirm proper replacement. The objective of the present study was to assess the utility of ultrasound to confirm GT placement in pediatric patients most at risk for complications from incorrect replacement. METHODS: This is a non-randomized cohort pilot trial to determine the sensitivity and specificity of ultrasound to confirm proper replacement of a GT in a Pediatric Emergency Department. RESULTS: We enrolled 55 pediatric subjects, of which 50 had ultrasound imaging after GT replacement in the PED prior to contrast injection. Ultrasound was found to have 96% sensitivity and 100% specificity for confirming GT placement. CONCLUSIONS: Ultrasound is a safe and reliable confirmatory study to confirm GT placement in pediatric patients, especially those at highest risk of complications from incorrect placement. LEVEL OF EVIDENCE: II.

Improved survival after hemostatic resuscitation: does the emperor have no clothes?

BACKGROUND: In light of recent data, controversy surrounds the apparent 30-day survival benefit of patients achieving a fresh frozen plasma (FFP) to packed red blood cell (PRBC) ratio of at least 1:2 in the face of massive transfusions (MT) (≥10 units of PRBC within 24 hours of admission). We hypothesized that initial studies suffer from survival bias because they do not consider early deaths secondary to uncontrolled exsanguinating hemorrhage. To help resolve this controversy, we evaluated the temporal relationship between blood product administration and mortality in civilian trauma patients receiving MT. METHODS: Patients requiring MT over a 22-month period were identified from the resuscitation registry of a Level I trauma center. Shock severity at admission and timing of shock-trauma admission, blood product administration, and death were determined. Patients were divided into high- and low-ratio groups (≥1:2 and<1:2 FFP:PRBC, respectively) and compared. Kaplan-Meier analysis and log-rank test was used to examine 24-hour survival. RESULTS: One hundred three patients (63% blunt) were identified (66 high-ratio and 37 low-ratio). Those patients who achieved a high-ratio in 24 hours had improved survival. However, severity of shock was less in the high-group (base excess: -8.0 vs. -11.2, p=0.028; lactate: 6.3 vs. 8.4, p=0.03). Seventy-five patients received MT within 6 hours. Of these, 29 received a high-ratio in 6 hours. Again, severity of shock was less in the high-ratio group (base excess: -7.6 vs. -12.7, p=0.008; lactate: 6.7 vs. 9.4, p=0.02). For these patients, 6-hour mortality was less in the high-group (10% vs. 48%, p<0.002). After accounting for early deaths, groups were similar from 6 hours to 24 hours. CONCLUSIONS: Improved survival was observed in patients receiving a higher plasma ratio over the first 24 hours. However, temporal analysis of mortality using shorter time periods revealed those who achieve early high-ratio are in less shock and less likely to die early from uncontrolled hemorrhage compared with those who never achieve a high-ratio. Thus, the proposed survival advantage of a high-ratio may be because of selection of those not likely to die in the first place; that is, patients die with a low-ratio not because of a low-ratio.
