Current progress in international pediatric emergency medicine.

PURPOSE OF REVIEW: Over the past four decades, pediatric emergency Medicine (PEM) has witnessed significant global development, with a notable increase in training programs and official recognition by regulatory bodies. However, disparities persist in the recognition of PEM as an independent subspecialty, availability of training programs on a global scale, academic recognition, and the ability to provide high-quality care to children worldwide. There is paucity of published literature regarding development of PEM globally. This review explores the current trends and challenges in international pediatric emergency medicine. RECENT FINDINGS: Current trends in international pediatric emergency medicine encompass the provision of training in pediatric-focused emergency and acute care, increased propagation of evidence-based guidelines specific to the care of children, the growth of collaborative research networks and interest groups within national and international societies. Simultaneously, the field continues to face challenges such as the lack of recognition, inequities in access, and a lack of dissemination of global PEM initiatives. SUMMARY: While recent advancements have significantly enhanced the state of international pediatric emergency medicine, including pediatric specific research networks and training programs, barriers still hinder its overall quality. Many of these obstacles are not unique to pediatric emergency medicine but are directly affected by financial disparities and lack of governmental and public recognition of the essential role of pediatric emergency care.

Management of Anaphylaxis Following Pre-Hospital Epinephrine Use in Children with Food-induced Anaphylaxis.

BACKGROUND: Previous guidelines recommend prompt epinephrine administration, followed by observation in the emergency department (ED). The need for transfer in all cases of anaphylaxis has recently been challenged. OBJECTIVE: We aimed to evaluate the need for additional ED treatment among children with anaphylaxis who received pre-hospital epinephrine. METHODS: Between 2011-2023, data were collected on symptoms, triggers, comorbidities, and pre-hospital and in-hospital management from children (<18 years) with food-induced anaphylaxis who received at least one dose of pre-hospital epinephrine presenting at 7 pediatric EDs. Multivariable logistic regression assessed factors associated with the usage of two or more pre-hospital EAI, epinephrine use in the ED, and hospital admission. RESULTS: Of 1127 children (mean 8.1 +/-5.3 years; 60.6% male) with food-induced anaphylaxis who used at least one EAI pre-hospital, the most common trigger was peanuts (25.3%). 209 (18.5%) received additional epinephrine in the ED, the majority of whom (88.0%) received one dose. 30 (2.7%) patients were admitted to hospital. Among all patients, severe reactions (cardiovascular instability/ cyanosis/ loss of consciousness) (adjusted odds ratio [aOR] 1.22; 95% confidence interval [CI] 1.12-1.33) and reactions to tree nuts (aOR 1.09; 95% CI 1.03-1.16) were associated with increased odds of in-hospital epinephrine use. Pre-hospital inhaled beta-agonists (aOR 1.08; 95% CI 1.01-1.16) use and severe reactions (aOR 1.13; 95% CI 1.05-1.22) were associated with the use of 2 or more EAI pre-hospital. CONCLUSION: A minority of anaphylaxis cases that used pre-hospital EAIs required additional treatment, supporting that shared decision making about transfer to ED works for the vast majority of patients.

Clinical characteristics and management of pediatric egg-induced anaphylaxis: A cross-sectional study.

BACKGROUND: Egg is the third most common food allergy in children; however, data on pediatric egg-induced anaphylaxis are sparse. OBJECTIVE: To describe the clinical characteristics, management, and outcomes of pediatric egg-induced anaphylaxis. METHODS: Children presenting with anaphylaxis were recruited from 13 emergency departments as part of the Cross-Canada Anaphylaxis Registry, from which data on anaphylaxis triggered by egg were extracted. Multivariate logistic regression was used to determine factors associated with prehospital epinephrine autoinjector (EAI) use and to compare anaphylaxis triggered by egg with other triggers of food-induced anaphylaxis (FIA). RESULTS: We recruited 302 children with egg-induced anaphylaxis. The mean age was 2.6 years (SD = 3.6), and 55.3% were male. Only 39.4% had previously been diagnosed with an egg allergy. Prehospital EAI use was 32.1%, but this was not significantly lower than in other triggers of FIA (P = .26). Only 1.4% of patients required hospital admission. Relative to other triggers of FIA, patients with egg-induced anaphylaxis were significantly younger (P < .001) and exhibited more vomiting (P = .0053) and less throat tightness (P = .0015) and angioedema (P < .001). CONCLUSION: To the best of our knowledge, this is the largest published cohort of pediatric egg-induced anaphylaxis. In this cohort, prehospital EAI use was very low. In addition, we identified certain symptoms that distinguish egg-induced from other triggers of FIA. Taken together, high suspicion is crucial in identifying egg-induced anaphylaxis, given the younger patient demographic and frequent lack of FIA history.

Milk-induced anaphylaxis among children presenting to Canadian emergency departments.

BACKGROUND: Cow's milk is one of the most common and burdensome allergens in pediatrics, and it can induce severe anaphylactic reactions in children. However, data on cow's milk-induced anaphylaxis are sparse. OBJECTIVE: To describe the epidemiology of pediatric cow's milk-induced anaphylaxis and to determine risk factors for repeat emergency department (ED) epinephrine administration. METHODS: Between April 2011 and May 2023, data were collected on children with anaphylaxis presenting to 10 Canadian EDs. A standardized form documenting symptoms, triggers, treatment, and outcome was used. Multivariate logistic regression was used. RESULTS: Of 3118 anaphylactic reactions, 319 milk-induced anaphylaxis cases were identified (10%). In the prehospital setting, 54% of patients with milk-induced anaphylaxis received intramuscular epinephrine. In those with milk-induced anaphylaxis, receiving epinephrine before presenting to the ED was associated with a reduced risk of requiring 2 or more epinephrine doses in the ED (adjusted odds ratio, 0.95 [95% CI, 0.90-0.99]). Children younger than 5 years of age were more likely to experience a mild reaction compared with that in older children, who experienced a moderate reaction more often (P < .0001). Compared with other forms of food-induced anaphylaxis, children presenting with milk-induced anaphylaxis were younger; a greater proportion experienced wheezing and vomiting, and less experienced angioedema. CONCLUSION: Prehospital epinephrine in pediatric milk-induced anaphylaxis is underused; however, it may decrease risk of requiring 2 ED epinephrine doses. Milk-induced anaphylaxis in children younger than 5 years of age may be less severe than in older children. Wheezing and vomiting are more prevalent in milk-induced anaphylaxis compared with that of other foods.

A Longitudinal Survey on Canadian Emergency Physician Burnout.

STUDY OBJECTIVE: Since Canada eased pandemic restrictions, emergency departments have experienced record levels of patient attendance, wait times, bed blocking, and crowding. The aim of this study was to report Canadian emergency physician burnout rates compared with the same physicians in 2020 and to describe how emergency medicine work has affected emergency physician well-being. METHODS: This longitudinal study on Canadian emergency physician wellness enrolled participants in April 2020. In September 2022, participants were invited to a follow-up survey consisting of the Maslach Burnout Inventory and an optional free-text explanation of their experience. The primary outcomes were emotional exhaustion and depersonalization levels, which were compared with the Maslach Burnout Inventory survey conducted at the end of 2020. A thematic analysis identified common stressors, challenges, emotions, and responses among participants. RESULTS: The response rate to the 2022 survey was 381 (62%) of 615 between September 28 and October 28, 2022, representing all provinces or territories in Canada (except Yukon). The median participant age was 42 years. In total, 49% were men, and 93% were staff physicians with a median of 12 years of work experience. 59% of respondents reported high emotional exhaustion, and 64% reported high depersonalization. Burnout levels in 2022 were significantly higher compared with 2020. Prevalent themes included a broken health care system, a lack of societal support, and systemic workplace challenges leading to physician distress and loss of physicians from the emergency workforce. CONCLUSION: We found very high burnout levels in emergency physician respondents that have increased since 2020.

EMS Use and Success Rates of Intraosseous Infusion for Pediatric Resuscitations: A Large Regional Health System Experience.

OBJECTIVE: Access of intraosseous (IO) compartments is a commonly used technique that is an invaluable asset in emergency resuscitation. Prehospital IO success rates using semi-automatic insertion devices vary between 70 and 100% of pediatric patients. There are limited data on time to insertion and duration of IO function in the prehospital setting. Recent studies limited to the pediatric emergency department (PED) setting have also suggested that IOs may be less successful in the infant population. We explored the use of IO access for pediatric resuscitation, encompassing the prehospital and pediatric emergency department (PED) settings. METHODS: This is a retrospective review of emergency medical services (EMS) patient care reports and PED data of patients aged 0-17 years old and transported by regional ground EMS agencies in Southwestern Ontario, Canada from 2012 to 2019. Mean and median time to first insertion and IO function (from insertion to IO failure, IV access, transfer to ICU, or death) were calculated. RESULTS: Successful prehospital IO access was achieved in 83.7% of patients. The median time required to achieve IO access was 4 min (IQR 3-7) and mean duration of IO function was 27.6 min (SD: 14.8). Patients less than 1 year old had fewer functional IOs (25.9% vs. 75.0%), more insertion attempts (2 vs. 1), and shorter duration of IO function (18.8 vs. 32.2 mins) than the older age group (p < 0.05). CONCLUSIONS: This is the first study to provide time to IO access and IO duration in the prehospital setting, and the first prehospital evidence to suggest inferior IO function in infants <1 year old, compared to other ages. This highlights unique challenges for infants that have implications for the PED, interfacility transport, and critical care settings.

Tree nut-induced anaphylaxis in Canadian emergency departments: Rate, clinical characteristics, and management.

BACKGROUND: Data are sparse regarding tree nut-induced anaphylaxis (TNA). OBJECTIVE: To characterize rate, clinical characteristics, and management of TNA in children (0-17 years old) across Canada and evaluate factors associated with severe reactions and epinephrine use. METHODS: Between April 2011 and May 2020, data were collected on children presenting to 5 emergency departments in Canada. Multivariate logistic analysis was used to evaluate factors associated with severe reactions (stridor, cyanosis, circulatory collapse, or hypoxia) and epinephrine use. RESULTS: Among 3096 cases of anaphylaxis, 540 (17%) were induced by tree nut. The median age was 5.2 (interquartile range, 2.5-9.5) years and 65.4% were of male sex. Among all reactions, 7.0% were severe. The major tree nuts accounting for anaphylaxis were cashew (32.8%), hazelnut (20.0%), and walnut (11.5%). Cashew-induced anaphylaxis was more common in British Columbia (14.0% difference [95% confidence interval (CI), 1.6-27.6]) vs Ontario and Quebec, whereas pistachio-induced anaphylaxis was more common in Ontario and Quebec (6.3% difference [95% CI, 0.5-12.2]). Prehospital and emergency department intramuscular epinephrine administration was documented in only 35.2% and 52.4% of cases, respectively. Severe reactions were more likely among of male sex (adjusted odds ratio [aOR], 1.05 [95% CI, 1.01-1.10]), older children (aOR, 1.00 [95% CI, 1.00-1.01]), and in reactions triggered by macadamia (aOR, 1.27 [95% CI, 1.03-1.57]). CONCLUSION: Different TNA patterns in Canada may be because of differences in lifestyle (higher prevalence of Asian ethnicity in British Columbia vs Arabic ethnicity in Ontario and Quebec). Intramuscular epinephrine underutilization urges for epinephrine autoinjector stocking in schools and restaurants, patient education, and consistent policies across Canada.

Sesame-induced anaphylaxis in pediatric patients from the cross-Canada anaphylaxis registry.

BACKGROUND: Sesame can cause severe allergic reactions and is a priority allergen in Canada. OBJECTIVE: To assess clinical characteristics and management of pediatric sesame-induced anaphylaxis and identify factors associated with epinephrine treatment. METHODS: Between 2011 and 2021, children with sesame-induced anaphylaxis presenting to 7 emergency departments (ED) in 4 Canadian provinces and 1 regional emergency medical service were enrolled in the Cross-Canada Anaphylaxis Registry. Standardized recruitment forms provided data on symptoms, severity, triggers, and management. Multivariate logistic regression evaluated associations with epinephrine treatment pre-ED and multiple epinephrine dosages. RESULTS: Of all food-induced anaphylactic reactions (n = 3279 children), sesame accounted for 4.0% (n = 130 children), of which 61.5% were boys, and the average (SD) age was 5.0 (4.9) years. Hummus containing sesame paste triggered 58.8% of reactions. In the pre-ED setting, 32.3% received epinephrine, and it was more likely to be used in boys (adjusted odds ratio [aOR], 1.27; 95% confidence interval [CI], 1.08-1.50) and those with a known food allergy (aOR, 1.36; 95% CI, 1.11-1.68]). In the ED, 47.7% of cases received epinephrine, with older children more likely to receive multiple epinephrine doses (aOR, 1.00; 95% CI, 1.00-1.02). CONCLUSION: In Canada, hummus is the major trigger of sesame-induced anaphylaxis. Knowledge translation focused on prompt epinephrine use and product-labeling policies are required to limit sesame reactions in communities.

Seafood-induced anaphylaxis in children presenting to Canadian emergency departments: Rates, clinical presentation, and management.

BACKGROUND: There is a lack of data on seafood-induced anaphylaxis in children in Canada. OBJECTIVE: To evaluate the rate, clinical features, and management of seafood-induced anaphylaxis in children presenting to emergency departments across Canada. METHODS: Children with anaphylaxis were recruited at 6 emergency departments between 2011 and 2020 as part of the Cross-Canada Anaphylaxis REgistry. A standardized form documenting symptoms, triggers, comorbidities, and management was used to collect data. RESULTS: There were 75 fish-induced and 71 shellfish-induced cases of suspected anaphylaxis, most of which were caused by salmon and shrimp, respectively. Mucocutaneous symptoms were most common, whereas respiratory symptoms were associated with patients with fish-induced reactions who have comorbid asthma (adjusted odds ratio [aOR], 1.18; 95% confidence interval [CI], 1.02-1.36). Prehospital epinephrine was underused (<35%), whereas in-hospital epinephrine was given to less than 60% of the patients. Among those with a known fish or shellfish allergy, prehospital epinephrine use was associated with known asthma (aOR 1.39 [95% CI, 1.05-1.84] and aOR 1.25 [95% CI, 1.02-1.54], respectively). Among children who were assessed by either skin test or specific immunoglobulin E, 36 patients (76.6%) with suspected fish-induced anaphylaxis and 19 patients (51.4%) with suspected shellfish-induced anaphylaxis tested positive. CONCLUSION: Prehospital epinephrine is underused in the management of seafood-induced anaphylaxis. Among children with known seafood allergy, prehospital epinephrine use is more likely if there is a known asthma comorbidity.

Clinical Suspicion and Language Translation in the Pediatric Emergency Department.

ABSTRACT: Elucidating a medical history and gaining patient consent and buy-in are difficult in any teenager presenting to a North American pediatric emergency department, but especially so when they present with limited English fluency. Translators can make this process easier, but both limited availability and impreciseness in translation can reduce their utility. We describe 2 teenage females who presented to our pediatric emergency department within 48 hours with similar presentations but no obvious organic cause or examination findings to suggest a specific diagnosis. We demonstrate how complex language translation issues in these adolescents contributed to prolonged diagnoses and advocate for independent interpreters to be available on first presentation to hospital.

High-flow nasal cannula implementation has not reduced intubation rates for bronchiolitis in Canada.

BACKGROUND AND OBJECTIVE: Bronchiolitis is the most common reason for admission to hospital in the first year of life, with increasing hospitalization rates in Canada. Respiratory support with high-flow nasal cannula (HFNC) is being routinely used in paediatric centres, though the evidence of efficacy is continuing to be evaluated. We examined the impact of HFNC on intubation rates, hospital and paediatric critical care unit (PCCU) length of stay (LOS), and PCCU admission rates in paediatric tertiary centres in Canada. METHODS: We conducted a multicentre, interrupted time series analysis to examine intubation rates pre- to postimplementation of HFNC for bronchiolitis. Data were obtained from the Canadian Institute for Health Information database. Paediatric tertiary centres that introduced HFNC between 2009 and 2014 were included, and data were collected from April 2005 to March 2017. RESULTS: A total of 17,643 patients met inclusion criteria. There was no significant change in intubation rates after the introduction of HFNC. There was a significant increase in PCCU admission, with a decrease in the PCCU LOS following the introduction of HFNC. There was no significant change in average hospital LOS after HFNC was introduced. CONCLUSIONS: This study adds to the evolving evidence showing that overall disease course is not modified by the use of HFNC. The initiation of HFNC in Canadian paediatric centres resulted in no significant change in intubation rates or average LOS in hospital, but had an increase in PCCU admissions. Careful monitoring of new technologies on their clinical impact as well as health care resource utilization is warranted.

Extreme heat and paediatric emergency department visits in Southwestern Ontario.

OBJECTIVE: The risk of adverse health events is expected to increase with hotter temperatures, particularly among the most vulnerable groups such as elderly persons and children. The objective of this study was to assess the association between extreme heat and daily emergency department visits among children (0 to 17 years) in Southwestern Ontario. METHODS: We examined the average maximum temperature, relative humidity, and daily paediatric emergency department visits in June through August of 2002 to 2019. We reviewed emergency department visits from two academic hospitals. Daily meteorological data from the local weather station were obtained from Environment and Climate Change Canada. RESULTS: Extreme heat, defined as the 99th percentile of the maximum temperature distribution, occurred at 33.1°C and was associated with an overall 22% increase in emergency department visits, compared to the reference temperature of 21°C. This association was mostly found between the second and fifth day after the exposure, suggesting a slightly delayed effect. The results of the sub-group analysis indicate that the risk of an emergency department visit due to infectious disease increases by 35% and the most pronounced association was noted in children aged 1 to 12 years. CONCLUSIONS: Extreme heat is associated with an increased incidence of emergency department visits in children. As temperatures continue to increase, strategies to mitigate heat-related health risks among children should be developed.

Risk of peanut- and tree-nut-induced anaphylaxis during Halloween, Easter and other cultural holidays in Canadian children.

BACKGROUND: It is not established whether the risk of anaphylaxis induced by peanuts or tree nuts in children increases at specific times of the year. We aimed to evaluate the risk of peanut-and tree-nut-induced anaphylaxis during certain cultural holidays in Canadian children. METHODS: We collected data on confirmed pediatric cases of anaphylaxis presenting to emergency departments in 4 Canadian provinces as part of the Cross-Canada Anaphylaxis Registry. We assessed the mean number of cases per day and incidence rate ratio (IRR) of anaphylaxis induced by unknown nuts, peanuts and tree nuts presenting during each of 6 holidays (Halloween, Christmas, Easter, Diwali, Chinese New Year and Eid al-Adha) versus the rest of the year. We estimated IRRs and 95% confidence intervals (CIs) using Poisson regression. RESULTS: Data were collected for 1390 pediatric cases of anaphylaxis between 2011 and 2020. Their median age was 5.4 years, and 864 (62.2%) of the children were boys. During Halloween and Easter, there were higher rates of anaphylaxis to unknown nuts (IRR 1.66, 95% CI 1.13-2.43 and IRR 1.71, 95% CI 1.21-2.42, respectively) and peanuts (IRR 1.86, 95% CI 1.12-3.11 and IRR 1.57, 95% CI 0.94-2.63, respectively) compared to the rest of the year. No increased risk of peanut- or tree-nut-induced anaphylaxis was observed during Christmas, Diwali, Chinese New Year or Eid al-Adha. Anaphylaxis induced by unknown nuts, peanuts and tree nuts was more likely in children aged 6 years or older than in younger children. INTERPRETATION: We found an increased risk of anaphylaxis induced by unknown nuts and peanuts during Halloween and Easter among Canadian children. Educational tools are needed to increase awareness and vigilance in order to decrease the risk of anaphylaxis induced by peanuts and tree nuts in children during these holidays.

A Rare Case of Cecal Bascule in a Child With Normal Neurodevelopment.

Cecal volvulus is a rare cause of bowel obstruction in adults and an extremely rare presentation in children. One form known as a cecal bascule has only previously been reported in children with neurodevelopmental issues or with severe chronic constipation. We present the case of a 10-year-old boy who presented with an acute history of left lower quadrant abdominal pain, who upon investigation was found to have a cecal bascule.

Determination of the Pretibial Soft Tissue Thickness in Children: Are Intraosseous Infusion Needles Long Enough?

OBJECTIVE: The EZ-IO intraosseous (IO) needle is available in 2 needle sizes for children based on the patient weight. To date, there is no published evidence validating the use of weight-based scaling in children. We hypothesized that pretibial subcutaneous tissue thickness (PSTT) does not correspond with patient weight but rather with age and body mass index (BMI). Our objective was to describe the relationship of a patient's PSTT to their weight, age, and BMI in children less than 40 kg. METHOD: One hundred patients who weighed less than 40 kg were recruited prospectively from October 2013 to April 2015 at a tertiary care pediatric emergency department. All sonographic assessments were performed by 1 of 2 emergency physicians certified in point-of-care ultrasound. A single sonographic image was taken over the proximal tibia corresponding to the site of IO insertion. In patients where both sonographers performed independent measurements, a Pearson correlation coefficient was determined. Univariate linear regression was performed to determine the relationship between age, weight, and BMI with PSTT. RESULTS: One hundred participants were recruited and ranged in age from 10 days to 14 years (mean [SD], 5.01 [3.14] years). Fifty-seven percent of participants were male. Patients' weights ranged from 3.5 to 39.3 kg (mean [SD], 21.42 [9.12] kg), and BMI ranged from 12.1 to 45.0 kg/m (mean [SD], 17.31 [4.00]). The mean (SD) PSTT across participants was 0.68 (0.2) cm. The intraclass correlation coefficient for agreement between the 2 sonographers was moderate (intraclass correlation coefficient, 0.602 [confidence interval, 0.385-0.757]). There were significant positive correlations between BMI and PSTT (r = 0.562, P = <0.001) as well as weight and PSTT (r = 0.293, P < 0.003). There was a weak correlation between age and PSTT (0.065, P = 0.521). CONCLUSIONS: Pretibial subcutaneous tissue thickness correlates most strongly with BMI, followed by weight, and weakly with age. Our findings suggest that current IO needle length recommendations should be based on BMI rather than weight. This would suggest that clinicians need to be aware that young patients in particular with large BMIs may pose problems with current weight-based needle length recommendations.

Comparison of Regularly Scheduled Ibuprofen Versus "Pro Re Nata" for Ankle Sprains in Children Treated in the Emergency Department: A Randomized Controlled Trial.

OBJECTIVE: We compared pain and degree of disability in patients with acute ankle sprains receiving regular scheduled ibuprofen versus pro re nata (PRN). METHODS: This study is a randomized single-blinded controlled trial of children aged 7 to 17 years presenting with acute ankle sprain to an emergency department. Patients were randomized to receive 10 mg/kg of ibuprofen per dose (maximum 600 mg) every 6 hours regular scheduled versus PRN. Outcome measures included a 100-mm visual analog scale pain and degree of disability at day 4. A sample size of 72 children had a power of 80% to detect a clinically meaningful difference of 20 mm between the regular and PRN group. RESULTS: We randomly assigned 99 patients to receive regular scheduled (n = 50) or PRN (n = 49) ibuprofen. Pain scores and degree of disability at day 4 showed no significant differences between groups. The rate of reported adverse effects was higher in the regular scheduled group (11.4% vs 9.5%) versus the PRN group. CONCLUSIONS: Our study suggests that there is little benefit from routinely using a regular scheduled ibuprofen regimen for acute pediatric ankle sprains.

Endogenous Glucocorticoid Response to Single-Dose Dexamethasone for Croup in Children: A Pharmacodynamic Study.

OBJECTIVES: Dexamethasone is associated with adrenal insufficiency in adults and children with chronic disease. This association has not been studied after single-dose oral dexamethasone, the standard of care for children with croup. We hypothesized that single-dose oral dexamethasone in children with croup is associated with a transient decrease in endogenous glucocorticoids. METHODS: We conducted a prospective, 2-arm, pharmacodynamic study of single-dose oral dexamethasone 0.6 mg/kg (maximum, 12 mg) in children older than 2 years with croup compared with controls (children with febrile upper respiratory tract infections who did not receive dexamethasone). Primary outcome was urinary 6ß-hydroxycortisol-cortisol ratio. RESULTS: Twenty-seven children were analyzed (22 with croup and 5 with upper respiratory tract infections). Median 6ß-hydroxycortisol-cortisol ratios before dexamethasone, the following morning, and on days 1, 3, and 7 were 2.8, 2.2, 2.0, 2.8, and 2.6, respectively. Among controls, the median 6ß-hydroxycortisol-cortisol ratios at the same time intervals was 1.9, 1.5, 1.8, 2.5, and 1.7, respectively. There were no significant differences in the change from time 0 between groups at any time point. There were no serious adverse events or infectious complications. CONCLUSIONS: Single-dose oral dexamethasone is not associated with decreased endogenous corticosteroid levels in children with croup. Future studies should use criterion standard tests to rule out suppression of the hypothalamic-pituitary-adrenal axis and be powered sufficiently to identify adverse clinical outcomes.

Mistaken Asymptomatic Carinal Foreign Body in a Child.

Foreign body aspirations are commonly seen in emergency departments (EDs) worldwide, presenting with cough, dyspnea, wheeze, and decreased air entry. Chest radiographs are commonly utilized diagnostic tools to confirm foreign object aspiration. The following is a case report of a child who presented in the ED with a carinal push-pin aspiration and a lack of respiratory symptoms; an extremely rare ED presentation of foreign body aspirations masquerading as a foreign body ingestion. This attests to the importance of conducting a lateral chest radiograph for diagnostic purposes to accurately interpret an esophageal or tracheal foreign body placement.

Improving Resident Well-Being During Shiftwork: Are Casino Shifts the Answer?

PURPOSE: The objective of this study is to quantitatively evaluate the well-being of residents doing casino shifts compared with those doing standard overnight shifts while working in an academic pediatric emergency department. METHODS: A randomized prospective survey study was performed over a period of 1 year on all residents who were scheduled to complete a 28-day block. Each block (28-day period) within the year was designated as either a "standard" or "casino" block. The standard overnight shifts were scheduled from midnight to 0800 hours, and casino shifts occurred from either 2000 to 0400 hours (casino A) and 0400 to 1200 hours (casino B). Participating residents were asked to complete both a preblock and postblock survey. The primary outcome was defined as differences in resident well-being as assessed by the brief resident wellness profile (BRWP). A mood faces graphical rating item to assess overall mood was used as a secondary outcome measures as well as a 10-item survey based on World Health Organization domains for quality of life and adapted to reflect completion of shiftwork. RESULTS: A total of 124 (90%) of 138 residents completed the study and were included in the analysis. No significant difference in resident well-being measured by BRWP between those in the standard and casino shift groups (17 ± 2.5 for preblock standard and 16.9 ± 2.8 for casino, P = 0.904; 17.1 ± 2.7 for postblock standard and 17.2 ± 3.1 for casino, P = 0.817), or in the relative change of the BRWP preblock and postblock between the 2 groups (standard, 0.35 ± 2.7; casino, 0.29 ± 3.0; P = 0.926). No significant difference in the mood faces rating scale scores or the 10-item postblock survey was found. CONCLUSIONS: In the first study examining the effects of casino shifts on trainees, we found no effect of standard overnight versus casino shifts on their well-being. This counters the benefits previously seen in emergency department consultant staff and highlights the need for more studies specifically in trainees.

Refractory Hypotension Caused by Prazosin Overdose Combined With Acetaminophen and Naproxen Toxicity: A Case Report and Review of the Literature.

BACKGROUND: Pediatric exposure to prazosin is unusual because it is most commonly indicated for the treatment of hypertension. Prazosin's increase in popularity as a treatment for posttraumatic stress disorder makes it important for emergency physicians to be aware of how to manage potential toxic ingestion because of prazosin overdose. CASE REPORT: A 16-year-old, 76-kg female presented after ingesting 110 mg of prazosin, 209.3 g of acetaminophen, and 55 g of naproxen. She was admitted to the pediatric intensive care unit for rapidly deteriorating hypotension (lowest blood pressure 47/19 mm Hg) refractory to aggressive fluid resuscitation and infusions of epinephrine and norepinephrine each at 0.5 mcg/kg/min. Stabilization of blood pressure was eventually achieved, and associated with use of a vasopressin infusion of 0.004 units/kg/min. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Because of the increasing exposure of children to prazosin, clinicians should be aware of the pharmacology behind alpha-1 antagonist overdose and consider treatment options, such as vasopressin, when hypotension is resistant to standard fluid and catecholamine therapy.
