RESUMEN
INTRODUCTION: Despite national policy changes, perspective changes on pregnancy and parenting in training are often lacking. We evaluated current viewpoints regarding pregnancy, parenthood, leave needs, and perceptions of support across trainees at our institution. METHODS: A cross-sectional survey was sent to all residents and fellows at a tertiary care academic center with >700 trainees. Demographic information, opinions on maternity and paternity leave, and opinions on institutional support and career goals were collected. The survey was sent via the Graduate Medical Education Office listserv -- 66 Accreditation Council for Graduate Medical Education (ACGME) programs and 40 non-ACGME programs. RESULTS: Seven hundred and forty-seven house officers received the survey with a response rate of 21.9% (n = 164). Of respondents, 81% were residents and 99 respondents were female (representing 31% of female trainees at our institution). Thirty-seven point two percent of respondents reported being parents. Twenty-five point three percent of respondents had been pregnant while a trainee with no statistical difference by specialty type (P = 0.0817). Statistically significant difference was noted in having children based on sex with men becoming parents at twice the rate of women (56% vs 26%, P < 0.001). No difference was noted between specialties on perceived support while pregnant and peripartum. Thirty percent of parent respondents reported thinking about leaving medical training after having children given family stressors. Statistical difference in thoughts of leaving medicine overall between females (46%) and males (17.6%; P = 0.0238). CONCLUSIONS: Men and women need support as they navigate becoming parents at a naturally stressful transition period. Females consider leaving medicine at twice the rate of males after becoming parents. Our institution and other ACGME programs need greater transparency and consistent leave practices that reflect changing times.

BACKGROUND: To evaluate if there are differences in outcomes for patients with stage III colon cancer in those from urban vs. rural commuting areas. METHODS: Data were evaluated on patients diagnosed with stage III colon cancer between 2012 and2018 from the Louisiana Tumor Registry. Patients were classified into rural and urban groups. Data on overall survival, time from diagnosis to surgery and time from surgery to chemotherapy, and sociodemographic factors (including race, age, and poverty level) were recorded. RESULTS: Of 2652 patients identified, 2159 were urban (81.4%) and 493 rural (18.6%). No age difference between rural and urban patients (p = 0.56). Stage IIIB accounted for 66.7%, followed by IIIC (21.6%) and IIIA (11%), with a significant difference between rural and urban patients based on stage (p = 0.02). There was no difference in the extent of surgery (p = 0.34) or tumor size (p = 0.72) between urban and rural settings. No difference in undergoing chemotherapy (p = 0.12). There was a statistically significant difference in receiving timely treatment for hospital volume (p < 0.0001) and poverty level (p < 0.0001), but no difference in time from diagnosis to surgery (p = 0.48), and time from surgery to chemotherapy (p = 0.27). Non-Hispanic Blacks were less likely to receive timely treatment when compared with non-Hispanic Whites for both surgery and adjuvant chemotherapy, (aHR 0.91, 95% CI 0.83-0.99) and (aHR 0.86, 95% CI 0.77-0.97), respectively. There was no difference in Kaplan-Meier overall survival curves comparing rural vs. urban patients (p = 0.77). CONCLUSIONS: There was no statistical difference in overall survival, time to surgery, and time to adjuvant chemotherapy between rural and urban patients with Stage III colon cancer.

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) causes a severe ischemia-reperfusion injury. Endovascular Perfusion Augmentation for Critical Care (EPACC) has emerged as a hemodynamic/mechanical adjunct to vasopressors and crystalloid for the treatment of post-REBOA ischemia-reperfusion injury. The objective of the study is to examine the impact of EPACC as a tool for a wean from complete REBOA compared to standard resuscitation techniques. METHODS: Nine swine underwent anesthesia and then a controlled 30% blood volume hemorrhage with 30 min of supraceliac total aortic occlusion to create an ischemia-reperfusion injury. Animals were randomized to standardized critical care (SCC) or 90 min of EPACC followed by SCC. The critical care phase lasted 270 min after injury. Hemodynamic markers and laboratory values of ischemia were recorded. RESULTS: During the first 90 min the intervention phase SCC spent 60% (54%-73%) and EPACC spent 91% (88%-92%) of the time avoiding proximal hypotension (<60 mm Hg), P = 0.03. There was also a statistically significant decrease in cumulative norepinephrine dose at the end of the experiment between SCC (80.89 mcg/kg) versus EPACC (22.03 mcg/kg), P = 0.03. Renal artery flow during EPACC was similar compared to SCC during EPACC, P = 0.19. But during the last hour of the experiment (after removal of aortic balloon) the renal artery flow in EPACC (2.9 mL/kg/min) was statistically significantly increased compared to SCC (1.57 mL/min/kg), P = 0.03. There was a statistically significant decrease in terminal creatinine in the EPACC (1.7 mg/dL) compared to SCC (2.1 mg/dL), P = 0.03. CONCLUSIONS: The 90 min of EPACC as a weaning adjunct in the setting of a severe ischemia-reperfusion injury after complete supraceliac REBOA provides improved renal flow with improvement in terminal creatinine compared to SCC with stabilized proximal hemodynamics and decreased vasopressor dose.

Necrotizing enterocolitis (NEC), a life-threatening intestinal disease, is becoming a larger proportionate cause of morbidity and mortality in premature infants. To date, therapeutic options remain elusive. Based on recent cell therapy studies, we investigated the effect of a human placental-derived stem cell (hPSC) therapy on intestinal damage in an experimental NEC rat pup model. NEC was induced in newborn Sprague-Dawley rat pups for 4 days via formula feeding, hypoxia, and LPS. NEC pups received intraperitoneal (ip) injections of either saline or hPSC (NEC-hPSC) at 32 and 56 h into NEC induction. At 4 days, intestinal macroscopic and histological damage, epithelial cell composition, and inflammatory marker expression of the ileum were assessed. Breastfed (BF) littermates were used as controls. NEC pups developed significant bowel dilation and fragility in the ileum. Further, NEC induced loss of normal villi-crypt morphology, disruption of epithelial proliferation and apoptosis, and loss of critical progenitor/stem cell and Paneth cell populations in the crypt. hPSC treatment improved macroscopic intestinal health with reduced ileal dilation and fragility. Histologically, hPSC administration had a significant reparative effect on the villi-crypt morphology and epithelium. In addition to a trend of decreased inflammatory marker expression, hPSC-NEC pups had increased epithelial proliferation and decreased apoptosis when compared with NEC littermates. Further, the intestinal stem cell and crypt niche that include Paneth cells, SOX9+ cells, and LGR5+ stem cells were restored with hPSC therapy. Together, these data demonstrate hPSC can promote epithelial healing of NEC intestinal damage.NEW & NOTEWORTHY These studies demonstrate a human placental-derived stem cell (hPSC) therapeutic strategy for necrotizing enterocolitis (NEC). In an experimental model of NEC, hPSC administration improved macroscopic intestinal health, ameliorated epithelial morphology, and supported the intestinal stem cell niche. Our data suggest that hPSC are a potential therapeutic approach to attenuate established intestinal NEC damage. Further, we show hPSC are a novel research tool that can be utilized to elucidate critical neonatal repair mechanisms to overcome NEC.

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 (4/2018-9/2019) of injured children <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 chi-square 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 (IQR) 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 (MTP; low-38%, high-46%, p = .34). Most patients sustained blunt injuries (70%). Median injury severity score was greater in high ratio patients (low-25, high-33, p = .01); however, hospital mortality was similar (low-24%, high-20%, p = .65) as was the risk of extended ventilator, ICU, and hospital days (all p > .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. MTP activation was not associated with receipt of high ratio transfusion, suggesting variability in MTP between centers. LEVEL OF EVIDENCE: Prospective cohort study, Level II.
RESUMEN
BACKGROUND: Firearm injury is the leading cause of death in children and prevention is the most effective method to reduce severe morbidity and mortality. Injury prevention programs have used community firearm lock giveaway events to promote safe firearm storage practices. The locks are generally simple and inexpensive devices suitable for mass distribution but may not possess the owner-desired attributes for use in the home. Because data on owner preferences for firearm lock type is lacking, we conducted a community survey to inform firearm safety outreach efforts. METHODS: We performed an anonymous cross-sectional survey at a large community fair. We elicited responses regarding reasons for firearm ownership, current storage practices, and preferences for firearm storage devices. Participants were offered a choice of a free trigger lock or cable lock and education on its use. RESULTS: Two-hundred and sixty-seven of 394 (67.7%) respondents reported firearm ownership, with 64.8% reporting children in the home regularly. Most (60.7%) owned handguns and cited personal protection as the main reason for ownership (88.4%). The ability to store the firearm loaded and the need for rapid access were identified as the main storage considerations. Respondents preferred trigger locks over cable locks at a rate of almost 2:1. CONCLUSIONS: The majority of firearm owners had handguns for self-defense. Owners preferred simple locking mechanisms that allowed the firearm to remain loaded. The pragmatic pediatric injury prevention program will include firearm owners' preferences when considering which lock to purchase and distribute during firearm injury prevention programs.

BACKGROUND: Acute care surgery (ACS) is well positioned to manage choledocholithiasis at the time of laparoscopic cholecystectomy, but barriers to laparoscopic common bile duct exploration (LCBDE) include experience and the perceived need for specialized equipment. The technical complexity of this pathway is generally seen as challenging. As such, LCBDE is historically relegated to the "enthusiast." However, a simplified, effective LCBDE technique as part of a "surgery first" strategy could drive wider adoption in the specialty most often managing these patients. To determine efficacy and safety, we sought to compare our initial ACS-driven experience with a simple, fluoroscopy-guided, catheter-based LCBDE approach during laparoscopic cholecystectomy (LC) to LC with endoscopic retrograde cholangiopancreatography (ERCP). METHODS: We reviewed ACS patients who underwent LCBDE or LC + ERCP (pre-/postoperative) at a tertiary care center in the 4 years since starting this surgery first approach. Demographics, outcomes, and length of stay (LOS) were compared on an intention to treat basis. Laparoscopic common bile duct exploration was performed via using wire/catheter Seldinger techniques under fluoroscopic guidance with flushing or balloon dilation of the sphincter as needed. Our primary outcomes were LOS and successful duct clearance. RESULTS: One hundred eighty patients were treated for choledocholithiasis with 71 undergoing LCBDE. The success rate of catheter-based LCBDE was 70.4%. Length of stay was significantly reduced for the LCBDE group compared with the LC + ERCP group (48.8 vs. 84.3 hours, p < 0.01). Of note, there were no intraoperative or postoperative complications in the LCBDE group. CONCLUSION: A simplified catheter-based approach to LCBDE is safe and associated with decreased LOS when compared with LC + ERCP. This simplified step-up approach may help facilitate wider LCBDE utilization by ACS providers who are well positioned for a timely surgery first approach in the management of uncomplicated choledocholithiasis.

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.

Introduction: Biliary dyskinesia is typically defined as a gallbladder ejection fraction (EF) <35% on hepatobiliary iminodiacetic acid scan with cholecystokinin stimulation (CCK-HIDA) testing. Cholecystectomy often leads to resolution of associated biliary colic symptoms. Alternatively, there is a subset of symptomatic patients with normal gallbladder EF on CCK-HIDA. It has been proposed that pain with CCK injection is more predictive of symptom resolution after cholecystectomy than low gallbladder EF. We reviewed our experience with pediatric patients with positive CCK provocation testing and a normal gallbladder EF in the absence of gallstones. Materials and Methods: We retrospectively reviewed the records of all pediatric patients with normal hepatobiliary iminodiacetic acid EFs (35%-80%) and pain with CCK injection at a tertiary care center between 2016 and 2020. Age, gender, body mass index (BMI), CCK-HIDA results, and pathology analysis were noted. Short- and long-term resolution of symptoms was determined by patient self-reporting at a mean of 3 weeks and 46 months, respectively. Results: Seventeen patients met inclusion criteria. Average age was 15.1 years (range, 12-17 years) with median BMI 24.9 (± 4.9 kg/m2). Mean CCK-HIDA EF was 56.3% (± 11.4%). In total, 62.5% of patients had evidence of chronic cholecystitis and/or cholesterolosis on pathology analysis. Of patients available for short-term and long-term postoperative follow-up, 80% and 83% reported complete or near complete resolution of symptoms, respectively. Conclusions: Normokinetic biliary dyskinesia is poorly understood but appears to be associated with chronic inflammation and cured by surgical intervention. Laparoscopic cholecystectomy results in resolution of symptoms for a majority of patients and should be considered in those with pain with CCK injection despite normal imaging studies.

BACKGROUND: Ischemia reperfusion injury causes a profound hyperdynamic distributive shock. Endovascular perfusion augmentation for critical care (EPACC) has emerged as a hemodynamic adjunct to vasopressors and crystalloid. The objective of this study was to examine varying levels of mechanical support for the treatment of ischemiareperfusion injury in swine. METHODS: Fifteen swine underwent anesthesia and then a controlled 30% blood volume hemorrhage followed by 30âmin of supra-celiac aortic occlusion to create an ischemia-reperfusion injury Animals were randomized to standardized critical care (SCC), EPACC with low threshold (EPACC-Low), and EPACC with high threshold (EPACC-High). The intervention phase lasted 270âmin after injury Hemodynamic markers and laboratory values of ischemia were recorded. RESULTS: During the intervention phase, SCC spent 82.4% of the time avoiding proximal hypotension (>60âmm Hg), while EPACC-Low spent 97.6% and EPACC-High spent 99.5% of the time avoiding proximal hypotension, Pâ <â0.001. Renal artery flow was statistically increased in EPACC-Low compared with SCC (2.29âmL/min/kg vs. 1.77âmL/âmin/kg, Pâ <â0.001), while renal flow for EPACC-High was statistically decreased compared with SCC (1.25âmL/min/kg vs. 1.77âmL/min/kg, Pâ <â0.001). EPACC animals required less intravenous norepinephrine, (EPACC-Low: 16.23mcg/kg and EPACC-High: 13.72âmcg/kg), compared with SCC (59.45âmcg/kg), Pâ=â0.049 and Pâ=â0.013 respectively. CONCLUSIONS: Compared with SCC, EPACC-High and EPACC-Low had decreased norepinephrine requirements with decreased frequency of proximal hypotension. EPACC-Low paradoxically had increased renal perfusion despite having a mechanical resistor in the aorta proximal to the renal arteries. This is the first description of low volume mechanical hemodynamic support in the setting of profound shock from ischemia-reperfusion injury in swine demonstrating stabilized proximal hemodynamics and augmented distal perfusion.

BACKGROUND: Advanced automatic crash notification (AACN) can improve triage decision-making by using vehicle telemetry to alert first responders of a motor vehicle crash and estimate an occupant's likelihood of injury. The objective was to develop an AACN algorithm to predict the risk that a pediatric occupant is seriously injured and requires treatment at a Level I or II trauma center. METHODS: Based on 3 injury facets (severity; time sensitivity; predictability), a list of Target Injuries associated with a child's need for Level I/II trauma center treatment was determined. Multivariable logistic regression of motor vehicle crash occupants was performed creating the pediatric-specific AACN algorithm to predict risk of sustaining a Target Injury. Algorithm inputs included: delta-v, rollover quarter-turns, belt status, multiple impacts, airbag deployment, and age. The algorithm was optimized to achieve under-triage ≤5% and over-triage ≤50%. Societal benefits were assessed by comparing correctly triaged motor vehicle crash occupants using the AACN algorithm against real-world decisions. RESULTS: The pediatric AACN algorithm achieved 25% to 49% over-triage across crash modes, and under-triage rates of 2% for far-side, 3% for frontal and near-side, 8% for rear, and 14% for rollover crashes. Applied to real-world motor vehicle crashes, improvements of 59% in under-triage and 45% in over-triage are estimated: more appropriate triage of 32,320 pediatric occupants annually. CONCLUSIONS: This AACN algorithm accounts for pediatric developmental stage and will aid emergency personnel in correctly triaging pediatric occupants after a motor vehicle crash. Once incorporated into the trauma triage network, it will increase triage efficiency and improve patient outcomes.

BACKGROUND: Biliary dyskinesia generally refers to a hypofunctioning gallbladder with an ejection fraction (EF) of <35% on hepatobiliary iminodiacetic acid scan with cholecystokinin stimulation (CCK-HIDA testing). In adults, biliary hyperkinesia has a defined association with biliary colic symptoms and can be relieved with surgical intervention. This clinical entity has not been well described in children or adolescents. In fact, only recently have we seen biliary hyperkinesia on HIDA at our centers. To that end, we reviewed our recent experience with adolescents who have presented and been treated for this unusual clinical entity. METHODS: With IRB approval, we retrospectively reviewed the records of all patients with abnormally high HIDA EFs (>80%) cared for by the pediatric surgery services at two tertiary care centers over the span of a three-year period. Age, sex, BMI, CCK-HIDA results, and preoperative testing and post-operative pathology were noted. Resolution of symptoms was determined by subjective patient self-reporting at postoperative visit. RESULTS: Eighteen patients met inclusion criteria. Average age 15.7 (range, 10-17 years), median BMI 27.3 (±8.2). Fifteen patients were female and 3 were male. Average CCK-HIDA EF was 91.6% (±5.2), 82.4% of the patients had evidence of chronic cholecystitis and/or cholesterolosis on pathology. Postoperatively, 82.4% of the patients available for follow up (n=17) reported complete or near complete resolution of symptoms. CONCLUSIONS: Biliary hyperkinesia is an emerging clinical entity in children and adolescents and has a similar presentation to biliary hypokinesia. While the pathophysiologic mechanism of pain is not fully elucidated, laparoscopic cholecystectomy appears to provide a surgical cure for these patients and should be considered in the differential for the patient with an unremarkable workup and history suggestive of biliary colic.
RESUMEN
PURPOSE: About half of pediatric blunt trauma patients undergo an abdominopelvic computed tomographic (CT) scan, while few of these require intervention for an intraabdominal injury. We evaluated the effectiveness of an evidence-based guideline for blunt abdominal trauma at a Level I pediatric trauma center. METHODS: Pediatric blunt trauma patients (nâ¯=â¯998) age 0-15â¯years who presented from the injury scene were evaluated over a 10â¯year period. After five years, we implemented our guideline in which the decision for CT was standardized based on mental status, abdominal examination, and laboratory results (alanine aminotransferase, aspartate aminotransferase, hemoglobin, urinalysis). RESULTS: There were no differences in age, GCS, SIPA or ISS scores between the patients before or after guideline implementation. Nearly half of the patients (48.3%) underwent CT scan before guideline implementation compared to 36.7% after (pâ¯<â¯0.0002). There was no difference in ISS (pâ¯=â¯0.44) between CT scanned patients in either group. No statistical differences were found in rate of intervention (pâ¯=â¯0.20), length of stay (pâ¯=â¯0.65), or readmission rate (0.2%) before versus after guideline implementation. There were no missed injuries. CONCLUSION: Implementation of an evidence-based clinical guideline for pediatric patients with blunt abdominal trauma decreases the rate of CT utilization while accurately identifying significant injuries. LEVEL OF EVIDENCE: III.

The management of choledocholithiasis in children and teenagers is often a two-procedure process with laparoscopic cholecystectomy (LC) and either pre- or post-operative endoscopic retrograde cholangiopancreatography (ERCP). The addition of laparoscopic common bile duct exploration (LCBDE) during LC can provide definitive treatment for choledocholithiasis during a single anesthetic event. In an effort to minimize sedation and radiation exposure from fluoroscopy, we have employed dilating balloons via a transcystic approach to stretch the sphincter of Oddi with subsequent ductal flushing. We describe the technique of balloon sphincteroplasty as a straightforward adjunct within the pediatric surgeon's skill set to manage choledocholithiasis during LC and our clinical experience.

In adults, the use of balanced resuscitation and study of massive transfusion protocols have led to improved outcomes for patients and continues to be refined. In children, massive transfusion protocols require further development and study to assess efficacy. Standardization is needed as transfusions and activation of protocols still rely on physician discretion in most pediatric settings. Further research is required to define the pediatric trauma population that will benefit, when to activate these protocols and how to use adjuncts such as tranexamic acid or factor VII in resuscitation. In addition, future implementation of technology such as hemoglobin-based oxygen carriers to increase survival should be studied further in this subset of patients.
RESUMEN
BACKGROUND: The purpose of this study was to determine the relationship between timing and volume of crystalloid before blood products and mortality, hypothesizing that earlier transfusion and decreased crystalloid before transfusion would be associated with improved outcomes. METHODS: A multi-institutional prospective observational study of pediatric trauma patients younger than 18 years, transported from the scene of injury with elevated age-adjusted shock index on arrival, was performed from April 2018 to September 2019. Volume and timing of prehospital, emergency department, and initial admission resuscitation were assessed including calculation of 20 ± 10 mL/kg crystalloid boluses overall and before transfusion. Multivariable Cox proportional hazards and logistic regression models identified factors associated with mortality and extended intensive care, ventilator, and hospital days. RESULTS: In 712 children at 24 trauma centers, mean age was 7.6 years, median (interquartile range) Injury Severity Score was 9 (2-20), and in-hospital mortality was 5.3% (n = 38). There were 311 patients(43.7%) who received at least one crystalloid bolus and 149 (20.9%) who received blood including 65 (9.6%) with massive transfusion activation. Half (53.3%) of patients who received greater than one crystalloid bolus required transfusion. Patients who received blood first (n = 41) had shorter median time to transfusion (19.8 vs. 78.0 minutes, p = 0.005) and less total fluid volume (50.4 vs. 86.6 mL/kg, p = 0.033) than those who received crystalloid first despite similar Injury Severity Score (median, 22 vs. 27, p = 0.40). On multivariable analysis, there was no association with mortality (p = 0.51); however, each crystalloid bolus after the first was incrementally associated with increased odds of extended ventilator, intensive care unit, and hospital days (all p < 0.05). Longer time to transfusion was associated with extended ventilator duration (odds ratio, 1.11; p = 0.04). CONCLUSION: Resuscitation with greater than one crystalloid bolus was associated with increased need for transfusion and worse outcomes including extended duration of mechanical ventilation and hospitalization in this prospective study. These data support a crystalloid-sparing, early transfusion approach for resuscitation of injured children. LEVEL OF EVIDENCE: Therapeutic, level IV.

Since the Transfusion Requirements in Critical Care trial, studies have shown that acutely ill patients can drift as a low as 5 g/dL. This study reviews a transfusion trigger change to 6.5 g/dL, which we hypothesize will conserve resources and improve quality of care. This is a retrospective chart review at an urban Level I trauma center from January through December 2015 after our trauma service changed the transfusion trigger from 7 to 6.5 g/dL. Outcomes in patients before (TT7) and after (TT6.5) the change in transfusion threshold were then compared. One hundred thirty-one discrete patients were included in this trial, with 285 instances of a hemoglobin of 7 g/dL or less and 178 transfusions. Seventy-two patients were before the change in threshold and 59 after. There was no change in length of hospital stay, ICU stay, ventilator days, mortality, and organ system failure after change in the transfusion threshold. After initiation of a more conservative threshold, 72 units of blood were saved. Decreased transfusion threshold was associated with no worse outcomes associated with decreased resource utilization.

The Advanced Trauma Life Support algorithm recommends bedside confirmatory techniques to confirm correct endotracheal tube (ETT) depth, a critical component in the care of pediatric trauma patients. We hypothesized that bedside confirmatory techniques are inaccurate and that early chest X-ray (CXR) would overcome such inaccuracies, allowing for faster intervention of malpositioned ETTs. An "A-OK" algorithm of immediate CXR following intubation in injured children aged <16 years was implemented. Eligible patients the years before and after implementation were identified. The accuracy of bedside confirmatory techniques (use of length-based depths and auscultation of breath sounds) was assessed. Post-"A-OK" patients were compared with pre-"A-OK" controls regarding the speed of malpositioned ETT repositioning. Twenty-eight post-"A-OK" cases and 23 pre-"A-OK" controls were identified. The groups did not differ in baseline characteristics. Bedside confirmatory techniques were accurate in only 61 per cent (length-based depth) and 58 per cent (auscultation of breath sounds) of patients. Time to ETT repositioning was significantly longer in pre-"A-OK" controls than in post-"A-OK" cases (35.2 ± 15.9 minutes vs 21.1 ± 11.8 minutes, P = 0.03). Bedside confirmatory techniques to determine ETT positioning are inaccurate in children. Inclusion of CXR in the primary survey is safe and allows for more rapid repositioning of malpositioned ETTs.

Objective: The objective was to develop a disability-based metric for motor vehicle crash (MVC) upper and lower extremity injuries and compare functional outcomes between children and adults.Methods: Disability risk (DR) was quantified using Functional Independence Measure (FIM) scores within the National Trauma Data Bank-Research Data System for the top 95% most frequently occurring Abbreviated Injury Scale (AIS) 3 extremity injuries (22 unique injuries). Pediatric (7-18 years), young adult (19-45 years), middle-aged (46-65 years), and older adult (66+ years) MVC occupants with an FIM score and at least one of the 22 extremity injuries were included. DR was calculated for each injury as the proportion of occupants who were disabled of those sustaining the injury. A maximum AIS-adjusted disability risk (DRMAIS) was also calculated for each injury, excluding occupants with AIS 4+ co-injuries.Results: Locomotion impairment was the most frequent disability type across all ages. DR and DRMAIS of the extremity injuries ranged from 0.06 to 1.00 (6%-100% disability risk). Disability risk increased with age, with DRMAIS increasing from 25.9% ± 8.6% (mean ± SD) in pediatric subjects to 30.4% ± 6.3% in young adults, 39.5% ± 6.6% in middle-aged adults, and 60.5 ± 13.3% in older adults. DRMAIS for upper extremity fractures differed significantly between age groups, with higher disability in older adults, followed by middle-aged adults. DRMAIS for pelvis, hip, shaft, knee, and other lower extremity fractures differed significantly between age groups, with older adult DRMAIS being significantly higher for each fracture type. DRMAIS for hip and lower extremity shaft fractures was also significantly higher in middle-aged occupants compared to pediatric and young adult occupants. The maximum AIS-adjusted mortality risk (MRMAIS, proportion of fatalities among occupants sustaining an MAIS 3 injury) was not correlated with DRMAIS for extremity injuries in pediatric, young adult, middle-aged, and older adult occupants (all R2 < 0.01). Disability associated with each extremity injury was higher than mortality risk.Conclusions: Older adults had significantly greater disability for MVC extremity injuries. Lower disability rates in children may stem from their increased physiological capacity for bone healing and relative lack of bone disease. The disability metrics developed can supplement AIS and other severity-based metrics by accounting for the age-specific functional implications of MVC extremity injuries.

BACKGROUND AND OBJECTIVES: Transumbilical laparoscopic-assisted appendectomy (TULAA) carries a high risk for surgical site infection. We investigated the effect of a bio-occlusive umbilical vacuum dressing on wound infection rates after TULAA for patients with acute appendicitis and compared to it with a conventional 3-port appendectomy with a nonvacuum dressing. METHODS: This study was a retrospective chart review of 1377 patients (2-20 years) undergoing laparoscopic appendectomy for acute appendicitis in 2 tertiary care referral centers from January 2007 through December 2012. Twenty-two different operative technique/dressing variations were documented. The 6 technique/dressing groups with >50 patients were assessed, including a total of 1283 patients. RESULTS: The surgical site infection rate of the 220 patients treated with TULAA and application of an umbilical vacuum dressing with dry gauze is 1.8% (95% CI, 0.0-10.3%). This compares to an infection rate of 4.1% (95% CI, 1.3-10.5%) in 97 patients with dry dressing without vacuum. In the 395 patients who received an umbilical vacuum dressing with gauze and bacitracin, the surgical site infection rate was found to be 4.3% (95% CI, 2.7-6.8%). CONCLUSIONS: Application of an umbilical negative-pressure dressing with dry gauze lowers the rate of umbilical site infections in patients undergoing transumbilical laparoscopic-assisted appendectomy for acute appendicitis.
