Characteristics and trends of pediatric firepit burns: insights for prevention and safety.

Introduction: As fire pits grow in popularity, so do the associated burn injuries. Our study examines pediatric fire pit burns characteristics to raise awareness and promote safety precautions. Methods: We conducted a retrospective review of pediatric patients (≤21 years) with firepit burns at a tertiary care hospital from 2016 to 2021. Results: Eighty-four patients were identified, of whom 70.2% were male, with a median age of 62 months. The median percent total body surface area burned was 2% (interquartile range (IQR)=1-4). Thirty-five (41.7%) patients were admitted and 7 (8.3%) underwent grafting. Neck and trunk burns had the highest grafting rates (66% and 33%, respectively). The hands (41.7%) and the lower extremities (27.4%) were the most frequently burned body areas. The leading causes of burns were ashes/hot coals (34.5%), flames (31.0%), and direct contact (25.0%), often resulting from falling into the fire (59.5%) or running or playing in activities near it (26.2%). Thirty-five (41.7%) were admitted for inpatient management, while 49 (58.3%) were treated as outpatient. Eleven (13.2%) underwent at least one reconstructive surgery, 7 (8.4%) had at least one rehabilitation visit, and 65 (77.4%) had follow-up clinic visits. The median length of stay was 2 days (IQR=1.0-3.5). The peak months for burns were from August through October (n=40, 46.0%), with an increase observed from 10 cases in 2016 to 20 cases in 2020. Conclusions: Given the significant proportion of firepit burns resulting from unsafe fire behaviors, it is crucial that caretakers are aware of proper firepit safety precautions. Level of evidence: III.

Ethnic disparities in pediatric appendicitis: the impact of hispanic ethnicity on presentation, complications, and postoperative outcomes.

PURPOSE: Our study investigates ethnic disparities in pediatric appendicitis, focusing on the impact of Hispanic ethnicity on presentation, complications, and postoperative outcomes. METHODS: We conducted a retrospective analysis of pediatric patients undergoing appendectomy for acute appendicitis from 2015 to 2020 using the National Surgical Quality Improvement Program-Pediatric database. We compared 30-day postoperative complications, postoperative length of stay, and postoperative interventions between Hispanic and non-Hispanic White patients. RESULTS: 65,976 patients were included, of which 23,462 (35.56%) were Hispanic and 42,514 (64.44%) non-Hispanic White. Hispanic children were more likely to present to the hospital with complicated appendicitis (31.75% vs. 25.15%, P < 0.0001) and sepsis (25.22% vs. 19.02%, P < 0.0001) compared to non-Hispanic White. Hispanics had higher rates of serious complications (4.06% vs. 3.55%, P = 0.001) but not overall complications (5.37% vs. 5.09%, P = 0.12). However, after multivariate analysis, Hispanic ethnicity was not associated with an increased rate of serious postoperative complications (OR 0.93, CI 0.85-1.01, P = 0.088); it was associated with less overall complications (OR 0.88, CI 0.81-0.96, P = 0.003) but a longer postoperative length of stay (OR 1.09, CI 1.04-1.14, P < 0.0001). CONCLUSION: Hispanic children are more likely to present with complicated appendicitis, contributing to increased postoperative complications. Notably, upon adjustment for the impact of complicated appendicitis, our findings suggest potentially favorable outcomes for Hispanic ethnicity. This emphasizes the need to understand delays in presentation to improve outcomes in the Hispanic population.

Cryoablation Reduces Opioid Consumption and Length of Stay After Pulmonary Metastasectomy.

INTRODUCTION: Intraoperative cryoablation of intercostal thoracic nerves is gaining popularity as a technique that decreases postoperative pain in thoracic surgery. Our study evaluates the efficacy and safety of cryoablation in pain management of pediatric cancer patients undergoing thoracotomy. METHODS: We reviewed cancer patients undergoing thoracotomies for pulmonary metastasis resection at our children's hospital from 2017 to 2023. Patients who received cryoablation were compared to those who did not. Our primary outcomes were self-reported postoperative pain scores (from 0 to 10) and opioid consumption, measured as oral morphine equivalent per kilogram. RESULTS: Thirty eight procedures were performed in 17 patients, of which 11 (64.7%) were males. Cryoablation was used in 14 (32.4%) procedures, while it was not in 24 (67.6%). Median age (17 y in both groups, P = 0.84) and length of surgery (300 cryoablation versus 282 no cryoablation, P = 0.65) were similar between the groups. Patients treated with cryoablation had a shorter hospital stay compared to those who did not (3.0 versus 4.5 d, respectively, P = 0.04) and received a lower total dose of opioids (2.2 oral morphine equivalent per kilogram versus 14.4, P = 0.004). No significant difference was noted in daily pain scores between the two groups (3.8 cryoablation versus 3.9 no cryoablation, P = 0.93). There was no difference in rates of readmissions between the cryoablation and no-cryoablation groups (14.3% versus 8.3%, P = 0.55). CONCLUSIONS: Our study suggests that cryoablation of the thoracic nerves during a thoracotomy is associated with reduced opiate consumption and shorter hospital stay. Cryoablation appears to be a promising technique for pain management in this patient population.

Access to Laparoscopic Pediatric Surgery: Do Ethnic and Racial Disparities Exist?

INTRODUCTION: Disparate access to laparoscopic surgery may contribute to poorer health outcomes among racial and ethnic minorities, especially among children. We investigated whether racial and ethnic disparities in laparoscopic procedures existed among four common surgical operations in the pediatric population in the United States. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program-Pediatrics, we conducted a retrospective review of pediatric patients, aged less than 18 y old, undergoing appendectomy, fundoplication, cholecystectomy, and colectomy from 2012 to 2021. To compare the surgical approach (laparoscopy or open), a propensity score matching algorithm was used to compare laparoscopic and open procedures between non-Hispanic Black with non-Hispanic White children and Hispanic with non-Hispanic White children. RESULTS: 143,205, 9,907, 4,581, and 26,064 children underwent appendectomy, fundoplication, colectomy, and cholecystectomy, respectively. After propensity score matching, non-Hispanic Black children undergoing appendectomy were found to be treated laparoscopically less than non-Hispanic White children (93.5% versus 94.4%, P = 0.007). With fundoplication, Hispanic children were more likely to be treated laparoscopically than White ones (86.7% versus 80.9%, P < 0.0001). There were no statistically significant differences between Black or Hispanic children and White children in rates of laparoscopy for other procedures. CONCLUSIONS: Though some racial and ethnic disparities exist with appendectomies and fundoplications, there is limited evidence to indicate that widespread inequities among common laparoscopic procedures exist in the pediatric population.

Effect of Red Blood Cell Transfusion on Regional Tissue Oxygenation in Pediatric Cardiac Surgery Patients.

BACKGROUND: Red blood cell (RBC) transfusions are used frequently in pediatric patients admitted to the intensive care unit (ICU) after cardiac surgery. To improve data-driven transfusion decision-making in the ICU, we conducted a retrospective analysis to assess the effect of RBC transfusion on cerebral and somatic regional oxygenation (rSO2). METHODS: We evaluated post- versus pre-RBC transfusion cerebral rSO2 and somatic rSO2 in all consecutive pediatric patients (age >28 days to <18 years) who underwent biventricular cardiac surgery at a single center between July 2016 and April 2020. RESULTS: The final data set included 263 RBC postoperative transfusion events in 75 patients who underwent 83 surgeries. The median pretransfusion hemoglobin was 10.6 g/dL (25th-75th percentile, 9.3-11.6). The median pretransfusion cerebral and somatic rSO2 were 63% (54-71) and 69% (55-80), which increased by a median of 3 percentage points (-2 to 6) and 2 percentage points (-3 to 6), respectively, after transfusion. After adjusting for pretransfusion hemoglobin, change in hemoglobin posttransfusion versus pretransfusion, and potential confounders (age, sex, and STAT surgical mortality risk score), the posttransfusion versus pretransfusion change in cerebral or somatic rSO2 was not statistically significant. Pretransfusion cerebral rSO2 (crSO2) was ≤50%, a previously described threshold for increased risk for unfavorable neurological outcome, for 22 of 138 (16%) transfusion events with complete pre- and post-crSO2 data. Sixteen of these 22 (73%) transfusions resulted in a posttransfusion crSO2 >50%. When restricting analysis to the first (index) transfusion after arrival to the ICU from the operating room (administered at a median of 1.15 postoperative days [25th-75th percentile, 0.84-1.93]), between-patient pretransfusion hemoglobin was not associated with pretransfusion crSO2 but within-patient posttransfusion versus pretransfusion hemoglobin difference was significantly associated with posttransfusion versus pretransfusion crSO2 difference (mean posttransfusion versus pretransfusion crSO2 difference, 2.54; 95% confidence interval, 0.50-4.48). CONCLUSIONS: In this study, neither cerebral nor somatic rSO2 increased significantly post- versus pre-RBC transfusion in pediatric cardiac surgery patients admitted to the ICU after biventricular repairs. However, almost three-quarters of transfusions administered when pretransfusion crSO2 was below the critical threshold of 50% resulted in a posttransfusion crSO2 >50%. In addition, the significant within-patient change in crSO2 in relation to the change in posttransfusion versus pretransfusion hemoglobin in the immediate postoperative period suggests that a personalized approach to transfusion following within-patient trends of crSO2 rather than absolute between-patient values may be an important focus for future research.

Impact of red blood cell transfusion on regional cerebral oxygen saturation during pediatric ECMO.

BACKGROUND: Low cerebral regional tissue oxygenation (crSO2) is associated with unfavorable neurological outcomes in children requiring extracorporeal membrane oxygenation (ECMO) support. Red blood cell (RBC) transfusion can improve brain oxygenation and crSO2 has been proposed as a noninvasive monitoring tool that could aid in RBC transfusion decision-making. However, how crSO2 responds to RBC transfusion is largely unknown. STUDY DESIGN AND METHODS: This was a retrospective, observational cohort study of all patients <21 years supported on ECMO at a single institution from 2011 to 2018. Transfusion events were grouped by pre-transfusion hemoglobin concentration (<10, 10- < 12, and ≥ 12 g/dL). Post- versus pre-transfusion crSO2 changes were analyzed using linear mixed-effects models. RESULTS: The final cohort included 830 transfusion events in 111 patients. Hemoglobin increased significantly post- versus pre-RBC transfusion (estimated mean increase of 0.47 g/dL [95% CI, 0.35-0.58], p < .001), as did crSO2 (estimated mean increase of 1.82 percentage points [95% CI, 1.23-2.40], p < .001). Larger improvements in crSO2 were associated with lower pre-transfusion crSO2 values (p < .001). There was no difference in mean change in crSO2 across the three hemoglobin groups in unadjusted analysis (p = .5) or after adjusting for age, diagnostic category, and pre-transfusion rSO2 (p = .15). Pre-transfusion crSO2 was <50% for 112 of 830 (13.5%) transfusion events, with only 30 (26.8%) crSO2 measurements noted to increase ≥50% post-transfusion. DISCUSSION: Among neonatal and pediatric patients on ECMO support, there was a statistically significant increase in crSO2 following RBC transfusion, although clinical significance needs to be investigated further. The effect was strongest among patients with lower crSO2 pre-transfusion.

Public perception of household risks for pediatric burn injuries and assessment of management readiness.

INTRODUCTION: Children are uniquely vulnerable to injury because of near-complete dependence on caregivers. Unintentional injury is leading cause of death in children under the age of 14. Burns are one of the leading causes of accidental and preventable household injuries, with scald burns most common in younger children and flame burns in older ones. Education is a key tool to address burn prevention, but unfortunately these injuries persist. Critically, there is a paucity of literature investigating adult comprehension with respect to potential risks of household burns. To date, no study has been performed to assess management readiness for these types of injuries without seeking medical care. METHODS: Qualtrics™ surveys were distributed to laypersons via Amazon Mechanical Turk. Demographics were self-reported. The survey was divided into two parts, management knowledge, and risk identification. The management part involved a photograph of a first-degree pediatric burn injury and required identification of the degree of injury and three potential initial managements. The risk-identification section required correctly identifying the most common mechanisms of burn injury for different age groups followed by general identification of 20 household burn risks. Survey responses were analyzed using two-tailed Student's t-tests and chi-square analyses, univariate and multivariate analysis, and linear regression. RESULTS: Of the 467 respondents, the mean age was 36.57 years, and was 59.7% (279) male. Only 3.2% of respondents were able to correctly identify all 20 potential risks listed in our survey. Additionally, only 4.5% of respondents correctly identified all three appropriate initial management options (cool water, sterile gauze, and over-the-counter analgesics) without misidentifying incorrect options. However, 56.1% of respondents were able to select at least one correct management option. For image-based injury classification, the most common response was incorrectly second-degree with 216 responses (42.2%) and the second-most common response was correctly first-degree with 146 responses (31.3%). Most respondents claimed they would not seek medical attention for the injury presented in the photograph (77.7%). When comparing the responses of individuals with children to those without, there were no statistically significant differences in ability to assess household risks for pediatric burns. For the entire population of respondents, the mean score for correctly identifying risks was 38%. CONCLUSION: This study revealed a significant gap in public awareness of household risks for pediatric burns. Furthermore, while most individuals would not seek medical care for a first-degree pediatric burn injury, they were readily available to identify proper initial management methods. This gap in knowledge and understanding of household pediatric burn injuries should be addressed with increased burn injury prevention education initiatives and more parental counseling opportunities.

Morbidity in children after fetoscopic endoluminal tracheal occlusion for severe congenital diaphragmatic hernia: Results from a multidisciplinary clinic.

BACKGROUND: Although fetoscopic endoluminal tracheal occlusion (FETO) was recently shown to improve survival in a multicenter, randomized trial of severe congenital diaphragmatic hernia (CDH), morbidity outcomes remain essentially unknown. The purpose of this study was to assess long-term outcomes in children with severe CDH who underwent FETO. METHODS: We conducted a prospective study of severe CDH patients undergoing FETO at an experienced North American center from 2015-2021 (NCT02710968). This group was compared to a cohort of non-FETO CDH patients with severe disease as defined by liver herniation, large defect size, and/or ECMO use. Clinical data were collected through a multidisciplinary CDH clinic. Statistics were performed with t-tests and Chi-squared analyses (p≤0.05). RESULTS: There were 18 FETO and 17 non-FETO patients. ECMO utilization was 56% in the FETO cohort. Despite significantly lower median observed/expected lung-to-head ratio (O/E LHR) in the FETO group, [FETO: 23% (IQR:18-25) vs. non-FETO: 36% (IQR: 28-41), p<0.001], there were comparable survival rates at discharge (FETO: 78% vs. non-FETO: 59%, p = 0.23) and at 5-years (FETO: 67% vs. non-FETO: 59%, p = 0.53) between the two cohorts. At a median follow up of 5.8 years, metrics of pulmonary hypertension, pulmonary morbidity, and gastroesophageal reflux disease improved among patients after FETO. However, most FETO patients remained on bronchodilators/inhaled corticosteroids (58%) and were feeding tube dependent (67%). CONCLUSIONS: These North American data show that prenatal tracheal occlusion, in conjunction with a long-term multidisciplinary CDH clinic, is associated with acceptable long-term survival and morbidity in children after FETO. LEVEL OF EVIDENCE: Level III.

Improving pathways to eliminate underrepresentation in the pediatric surgery workforce: A call to action.

Despite progress, diversity and minority representation within the pediatric surgery workforce still does not match the expansive backgrounds of the patients we treat. The problem stems from underrepresentation of minority populations at every step along the pediatric surgery training pathway. Strategies aimed at improving diversity and representation in medical school, general surgery residencies, and ultimately pediatric surgery fellowship are necessary to assemble a more diverse pool of pediatric surgeons. The aim of this paper is to review the current demographic make-up of medical and surgical specialties, highlight the value of diversity, and provide evidence-based strategies for increasing minority representation throughout the pediatric surgery pathway. Future patients will be better served with a more representative pediatric surgery workforce.

Effect of implementing an enhanced recovery protocol for pediatric colorectal surgery on complication rate, length of stay, and opioid use in children.

Introduction In the past two decades, Enhanced Recovery After Surgery (ERAS) pathways for adults have improved efficiency of care and decreased length of stay (LOS) without increasing postoperative complications. The effects of enhanced recovery pathways for children are less well known. In this retrospective cohort study, we evaluated the effects of an enhanced recovery protocol (ERP) implementation in children undergoing colorectal surgery. Methods We introduced a colorectal ERP in 2017. Children and young adults (ages 2-22 years) were divided into pre-intervention (2014-2016) and post-intervention groups (2017-2019) for analysis. We abstracted data, including demographics, primary surgery, LOS, postoperative pain scores, and postoperative complications. Results A total of 432 patients were included. Of those,148 (34%) were pre-ERP implementation and 284 (66%) were post-ERP implementation. Post-ERP patients experienced significantly shorter LOS (5.7 vs. 8.3 days, p<0.01); required less intraoperative local anesthetic (9.5% vs. 38.5%, p<0.01) because 55% of patients received an epidural and 18% received an abdominal plane block; and used less postoperative opioid (62.5% vs. 98.7%, p<0.01) than did pre-ERAS patients. After protocol implementation, average pain scores were lower on postoperative day 1 (3.6 vs. 4.5, p<0.05) and across the hospitalization (3.0 vs. 4.0, p<0.01). Conclusion Enhanced recovery pathways decrease LOS, opioid use, and postoperative pain scores for children undergoing colorectal surgery and should be considered for this patient population.

Evaluation of the Surgical Management of Achalasia in Children and Young Adults.

INTRODUCTION: Achalasia is a rare esophageal motility disorder in children and is most often treated with the Heller myotomy. This study examines the current trends in surgical management of achalasia and evaluates the safety of the Heller myotomy in children compared to the young adult population. METHODS: This is a retrospective cohort study of children and young adults aged ≤25 y undergoing a Heller myotomy for achalasia. Data were collected using the adult and pediatric National Surgical Quality Improvement Program databases from 2012 to 2018. Patient characteristics, comorbidities, and 30-d outcomes were evaluated. Operative details of interest included surgical specialty and the use of esophagogastroduodenoscopy and esophageal manometry. Outcomes included operative time, length of stay, reoperation, and other postoperative complications. RESULTS: A total of 178 pediatric and 202 young adult patients were included in the study. The majority of surgeries were performed laparoscopically (85.4% pediatric and 95.0% adult). Esophageal manometry was only used in pediatric cases, and esophagogastroduodenoscopy was used in 35 (19.7%) pediatric and 41 (20.3%) adult cases. Thirty-day complications occurred in 7 (3.9%) children and 3 (1.5%) adults. The median operative time for children was 174.5 min and the median length of stay (LOS) was 2 d. The median operative time for adults was 126 min and the median LOS was 1 d (P < 0.01 for both). There was a longer LOS for cases performed by pediatric surgeons (P = 0.03). CONCLUSIONS: Heller myotomy continues to be a very safe operation for achalasia with minimal short-term morbidity.

Factors Associated With Pediatric Burn Clinic Follow-up After Emergency Department Discharge.

Attrition between emergency department discharge and outpatient follow-up is well documented across a variety of pediatric ailments. Given the importance of outpatient medical care and the lack of related research in pediatric burn populations, we examined sociodemographic factors and burn characteristics associated with outpatient follow-up adherence among pediatric burn patients. A retrospective review of medical records was conducted on patient data extracted from a burn registry database at an urban academic children's hospital over a 2-year period (January 2018-December 2019). All patients were treated in the emergency department and discharged with instructions to follow-up in an outpatient burn clinic within 1 week. A total of 196 patients (Mage = 5.5 years; 54% male) were included in analyses. Average % TBSA was 1.9 (SD = 1.5%). One third of pediatric burn patients (33%) did not attend outpatient follow-up as instructed. Older patients (odds ratio [OR] = 1.00; 95% confidence interval [CI]: [0.99-1.00], P = .045), patients with superficial burns (OR = 9.37; 95% CI: [2.50-35.16], P = .001), patients with smaller % TBSA (OR = 1.37; 95% CI: [1.07-1.76], P = .014), and patients with Medicaid insurance (OR = 0.22; 95% CI: [0.09-0.57], P = .002) or uninsured/unknown insurance (OR = 0.07; 95% CI: [0.02-0.26], P = .000) were less likely to follow up, respectively. Patient gender, race, ethnicity, and distance to clinic were not associated with follow-up. Follow-up attrition in our sample suggests a need for additional research identifying factors associated with adherence to follow-up care. Identifying factors associated with follow-up adherence is an essential step in developing targeted interventions to improve health outcomes in this at-risk population.

A dual-institutional study on first-year practice outcomes of pediatric surgeons who trained in the era of work hour restrictions.

BACKGROUND: In July 2003, an 80-h work week restriction for residencies was mandated. This was met with skepticism regarding its potential impact on operative training. We hypothesized no difference in outcomes for pediatric surgeons who trained under duty hour restrictions compared to historical complication rates. METHODS: Dual-institutional review of pediatric patients who underwent five of the most common operations (2013-2018) by first-year pediatric surgeons who trained under duty hour restrictions was performed. Tests of proportions were used to compare complication rates to published rates on data collected prior to 2003. RESULTS: Patient mean age was 10.1 years. No significant differences (p values > 0.05) were found in laparoscopic appendectomy rates of infection, bleeding or intra-abdominal abscess compared to previously published rates. Pyloromyotomy rates of infection or duodenal perforation were not different. No differences were detected in rates of infection, recurrence or testicular atrophy for inguinal hernia repair. Umbilical hernia rates of infection, bleeding, and recurrence were also not different. There was no difference in CVC rates of hemopneumothoraces; significantly more bleeding events were detected (1.2% vs. 0.1%; p value = 0.04). CONCLUSION: In this study, first-year complication rates of pediatric surgeons who trained under duty hour restrictions were not significantly different when compared to published rates.

Appendectomy and Cholecystectomy Outcomes for Pediatric Cancer Patients with Leukopenia: A NSQIP-Pediatric Study.

BACKGROUND: Children with cancer often develop leukopenia which may impair wound healing and increase surgical complication rates. When leukopenic children with cancer develop an acute surgical condition, the optimal management strategy remains unclear. This study examined the effect of preoperative leukopenia on postoperative outcomes in children with cancer who underwent an appendectomy or cholecystectomy. METHODS: We retrospectively identified cancer patients undergoing an appendectomy or cholecystectomy from the National Surgical Quality Improvement Program-Pediatric database from 2012-2018. Demographics and perioperative characteristics were compared by leukopenia status (WBC <4 vs. ≥4 × 10^3/mL). Postoperative length of stay (LOS) and 30-day composite complications, including infections, reoperations, and readmissions, were analyzed for each procedure using multivariate regression. RESULTS: There were 227 children who underwent an appendectomy and 101 children who underwent a cholecystectomy. Leukopenia was seen in 93 (41.0%) appendectomy and 57 (56.4%) cholecystectomy cases. Nineteen (8.4%) appendectomy patients and six (5.9%) cholecystectomy patients developed a postoperative complication. The median postoperative LOS was 2 days (IQR 1-6 days) for appendectomy and 1 day (IQR 1-2.5 days) for cholecystectomy cases. After multivariate analyses, leukopenia was not associated with increased postoperative complications after an appendectomy (OR 0.55, P = 0.36) or cholecystectomy (OR 0.39, P = 0.37). There was no significant difference in postoperative LOS based on leukopenia status for children who underwent an appendectomy (P = 0.82) or cholecystectomy (P = 0.37). CONCLUSION: In pediatric cancer patients, leukopenia was not associated with increased short-term postoperative complications or longer postoperative LOS after either an appendectomy or cholecystectomy. These results support that operative management can be performed safely in pediatric appendicitis and cholecystitis in leukopenic cancer patients.

Predictors of Follow-up Compliance in Pediatric Burn Patients During the Time of COVID.

The effect of the COVID-19 pandemic has led to increased isolation and potentially decreased access to healthcare. We therefore evaluated the effect of COVID-19 on rates of compliance with recommended post-injury follow-up. We hypothesized that this isolation may lead to detrimental effects on adherence to proper follow-up for children with burn injuries. We queried the registry at an ABA-verified Level 1 pediatric burn center for patients aged 0-18 years who were treated and released from March 30 to July 31, 2020. As a control, we included patients treated during the same time frame from 2016 to 2019. Patient and clinical factors were compared between the COVID and pre-COVID cohorts. Predictors of follow-up were compared using chi-squared and Kruskal-Wallis tests. Multivariable logistic regression was used to evaluate for predictors of compliance with follow-up. A total of 401 patients were seen and discharged from the pediatric ED for burns. Fifty-eight (14.5%) of these patients were seen during the pandemic. Burn characteristics and demographic patterns did not differ between the COVID and pre-COVID cohorts. Likewise, demographics did not differ between patients with follow-up and those without. The rate of compliance with 2-week follow-up was also not affected. Burn size, burn depth, and mechanism of injury all were associated with higher compliance to follow up. After adjusting for these variables, there was still no difference in the odds of appropriate follow-up. Despite concerns about decreased access to healthcare during COVID, follow-up rates for pediatric burn patients remained unchanged at our pediatric burn center.

Pediatric arterial femoral cannulations for extracorporeal membrane oxygenation: Does size really matter?

BACKGROUND: No studies exist comparing various femoral artery cannula sizes in children on ECMO. We hypothesize that smaller arterial cannulas provide adequate flow in children while decreasing vascular complications. METHODS: We performed a retrospective review of the ELSO database from 2012-2017. We included children undergoing femoral venoarterial ECMO between ages 12 and 18 years and weighing more than 30 kg. Arterial cannula sizes were grouped as: 15-16Fr, 17-18Fr, 19-20Fr and ≥21Fr. Arterial pump flow, bleeding complications, limb ischemia, and mechanical complications were compared by cannula size. Distal perfusion catheter and percutaneous placement were also compared for complications. RESULTS: A total of 429 patients were included with 28.2% 15-16Fr, 32.2% 17-18Fr, 22.8% 19-20Fr, and 16.8% ≥ 21Fr arterial femoral cannulas. Median age was lower in the 15-16Fr group compared to the largest cannula group (14.7 years vs 15.5 years, p < 0.01). The overall mean arterial flow was 57.4 +/- 17.0 mL/kg/min with no difference in mean arterial flow rates among the cannula size groups (p = 0.85). There were no significant differences in all complications, bleeding or mechanical complications by arterial cannula size group. However, there was an increased risk of limb ischemia in the ≥21Fr group compared to the 15-16Fr group (OR 4.38, 95% CI 1.24-15.43; p = 0.02). Distal perfusion catheter was shown to increase the risk of mechanical complications (OR 1.78; 95% CI 1.03-3.07; p = 0.04) but did not make a statistically significant difference in limb ischemia (OR 0.37; 95% CI 0.12-1.11; p = 0.07). CONCLUSION: Review of the ELSO database demonstrates that the use of larger arterial cannulas compared to 15-16Fr cannulas are not needed to achieve similar pump flows for hemodynamic support but the largest cannula sizes may increase the risk of ischemic complications.

Unusual case of delayed congenital diaphragmatic hernia in Loeys-Dietz syndrome: a case report.

Congenital diaphragmatic hernias rarely present after 2 months of age and are typically diagnosed in the perinatal period. Moderate to severe diaphragmatic hernias present with respiratory symptoms, while late-onset hernias have a more varied presentation, depending on the age and content of the hernia. Very rarely, such hernias are found on incidental imaging, in which surgical repair is frequently recommended. A young girl with Loeys-Dietz syndrome and prior abdominal surgeries presents with 1-year history of increasingly severe, intermittent, abdominal and left shoulder pain. Prior imaging incidentally revealed a left diaphragmatic hernia with omentum protruding into the thoracic cavity. This was managed expectantly due to her other medical and surgical issues. Serial imaging revealed that the herniated omentum was increasing in size and symptoms began to develop. An uncomplicated primary thoracoscopic repair was performed. We report the first case of a congenital diaphragmatic hernia in a patient with Loeys-Dietz syndrome.

Increased proportion of physical child abuse injuries at a level I pediatric trauma center during the Covid-19 pandemic.

BACKGROUND AND OBJECTIVES: The Covid-19 pandemic has forced mass closures of childcare facilities and schools. While these measures are necessary to slow virus transmission, little is known regarding the secondary health consequences of social distancing. The purpose of this study is to assess the proportion of injuries secondary to physical child abuse (PCA) at a level I pediatric trauma center during the Covid-19 pandemic. METHODS: A retrospective review of patients at our center was conducted to identify injuries caused by PCA in the month following the statewide closure of childcare facilities in Maryland. The proportion of PCA patients treated during the Covid-19 era were compared to the corresponding period in the preceding two years by Fisher's exact test. Demographics, injury profiles, and outcomes were described for each period. RESULTS: Eight patients with PCA injuries were treated during the Covid-19 period (13 % of total trauma patients), compared to four in 2019 (4 %, p < 0.05) and three in 2018 (3 %, p < 0.05). The median age of patients in the Covid-19 period was 11.5 months (IQR 6.8-24.5). Most patients were black (75 %) with public health insurance (75 %). All injuries were caused by blunt trauma, resulting in scalp/face contusions (63 %), skull fractures (50 %), intracranial hemorrhage (38 %), and long bone fractures (25 %). CONCLUSIONS: There was an increase in the proportion of traumatic injuries caused by physical child abuse at our center during the Covid-19 pandemic. Strategies to mitigate this secondary effect of social distancing should be thoughtfully implemented.
