OBJECTIVE This study assessed whether a single diabetic ketoacidosis (DKA) episode is associated with cognitive declines in children with newly diagnosed type 1 diabetes and whether the same is true in children who had previously been diagnosed after accounting for variations in glycemic control and other relevant factors. RESEARCH DESIGN AND METHODS We prospectively enrolled 758 children, 6–18 years old, who presented with DKA in a randomized multisite clinical trial evaluating intravenous fluid protocols for DKA treatment. DKA was moderate/severe in 430 children and mild in 328 children. A total of 392 children with DKA had new onset of type 1 diabetes, and the rest were previously diagnosed. Neurocognitive assessment occurred 2–6 months after the DKA episode. A comparison group of 376 children with type 1 diabetes, but no DKA exposure, was also enrolled. RESULTS Among all patients, moderate/severe DKA was associated with lower intelligence quotient (IQ) (β = −0.12, P < 0.001), item-color recall (β = −0.08, P = 0.010), and forward digit span (β = −0.06, P = 0.04). Among newly diagnosed patients, moderate/severe DKA was associated with lower item-color recall (β = −0.08, P = 0.04). Among previously diagnosed patients, repeated DKA exposure and higher HbA1c were independently associated with lower IQ (β = −0.10 and β = −0.09, respectively, P < 0.01) and higher HbA1c was associated with lower item-color recall (β = −0.10, P = 0.007) after hypoglycemia, diabetes duration, and socioeconomic status were accounted for. CONCLUSIONS A single DKA episode is associated with subtle memory declines soon after type 1 diabetes diagnosis. Sizable IQ declines are detectable in children with known diabetes, suggesting that DKA effects may be exacerbated in children with chronic exposure to hyperglycemia.

Pediatric pain control in the emergency department (ED) remains problematic. This quantifiable metric may be positively affected by the utilization of a rapid triage provider (RTP). This is a retrospective case control study of pediatric patients requiring either ketorelac intravenous (IV) or morphine IV for painful conditions. Patients in the control group were managed according to standard nursing-driven triage process. Patients in the RTP group were seen by the standard triage team as well as by the RTP.We identified 114 patients who required IV pain medications. The mean time from arrival to pain medication administration for the RTP group as compared with the control group was 47 and 64 minutes (P = 0.02). Similarly, the mean time from arrival to IV pain medication order placement was 15 and 43 minutes (P < 0.01). An RTP improves pain control in the pediatric ED via more efficient order placement and IV pain medication administration.

Objectives The objective of this study was to investigate the significance and prevalence of lactic acidosis in pediatric diabetic ketoacidosis (DKA) presenting to the emergency department. Methods A retrospective cohort study of children (age ≤ 21 years) presenting to a tertiary care emergency department in DKA from December 1, 2015 to December 1, 2018. Patients needed to have DKA requiring admission to the pediatric intensive care unit and have had a lactate level collected while in the emergency department to be included. Results 92 patients resulting in 113 encounters had DKA and a lactate level collected in the emergency department. The mean lactate level was 3.5 mmol/L (±SD 2.1). 72 (63.7%) encounters had lactic acidosis (p Conclusions Lactic acidosis is a common finding in pediatric DKA patients presenting to the emergency department. Serum lactate alone should not be used as an outcome predictor in pediatric DKA.

BACKGROUND: Non-contrast magnetic resonance imaging (MRI) and ultrasound studies in pediatric patients with suspected appendicitis are often non-diagnostic. The primary objective of this investigation was to determine if combining these non-diagnostic imaging results with white blood cell (WBC) cutoffs improves their negative predictive values (NPVs). METHODS: A retrospective chart review was conducted including patients ≤18 years old with suspected appendicitis who had MRI performed with or without a preceding ultrasound study in a pediatric emergency department. Imaging results were sorted into 2 diagnostic and 5 non-diagnostic categories. NPVs were calculated for the non-diagnostic MRI and ultrasound categories with and without combining them with WBC cutoffs of

OBJECTIVES Diabetic ketoacidosis (DKA) is typically characterized by low or low-normal serum sodium concentrations, which rise as hyperglycemia resolves. In retrospective studies, researchers found associations between declines in sodium concentrations during DKA and cerebral injury. We prospectively investigated determinants of sodium concentration changes and associations with mental status alterations during DKA. METHODS Using data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in Diabetic Ketoacidosis Trial, we compared children who had declines in glucose-corrected sodium concentrations with those who had rising or stable concentrations. Children were randomly assigned to 1 of 4 intravenous fluid protocols that differed in infusion rate and sodium content. Data from the first 4, 8, and 12 hours of treatment were analyzed for 1251, 1086, and 877 episodes, respectively. RESULTS In multivariable analyses, declines in glucose-corrected sodium concentrations were associated with higher sodium and chloride concentrations at presentation and with previously diagnosed diabetes. Treatment with 0.45% (vs 0.9%) sodium chloride fluids was also associated with declines in sodium concentration; however, higher rates of fluid infusion were associated with declines in sodium concentration only at 12 hours. Frequencies of abnormal Glasgow Coma Scale scores and clinical diagnoses of cerebral injury were similar in patients with and without declines in glucose-corrected sodium concentrations. CONCLUSIONS Changes in glucose-corrected sodium concentrations during DKA treatment are influenced by the balance of free-water loss versus sodium loss at presentation and the sodium content of intravenous fluids. Declines in glucose-corrected sodium concentrations are not associated with mental status changes during treatment.

Background Research demonstrates that timely recognition and treatment of sepsis can significantly improve pediatric patient outcomes, especially regarding time to intravenous fluid (IVF) and antibiotic administration. Further research suggests that underlying chronic disease in a septic pediatric patient puts them at higher risk for poor outcomes. Objective To compare treatment time for suspected sepsis and septic shock in pediatric patients with chronic disease versus those without chronic disease seen in the Pediatric Emergency Department (PED). Methods We reviewed patient data from a pediatric sepsis outcomes dataset collected at two tertiary care pediatric hospital sites from January 2017–December 2018. Patients were stratified into two groups: those with and without chronic disease, defined as any patient with at least one of eight chronic health conditions. Inclusion criteria: patients seen in the PED ultimately diagnosed with sepsis or septic shock, patient age 0 to 20 years and time zero for identification of sepsis in the PED. Exclusion criteria: time zero unavailable, inability to determine time of first IVF or antibiotic administration or patient death within the PED. Primary analysis included comparison of time zero to first IVF and antibiotic administration between each group. Results 312 patients met inclusion criteria. 169 individuals had chronic disease and 143 did not. Median time to antibiotics in those with chronic disease was 41.9 min versus 43.0 min in patients without chronic disease (p = 0.181). Time to first IVF in those with chronic disease was 22.0 min versus 12.0 min in those without (p = 0.010). Those with an indwelling line/catheter (n = 40) received IVF slower than those without (n = 272), with no significant difference in time to antibiotic administration by indwelling catheter status (p = 0.063). There were no significant differences in the mode of identification of suspected sepsis or septic shock between those with versus without chronic disease (p = 0.27). Conclusions Study findings suggest pediatric patients with chronic disease with suspected sepsis or septic shock in the PED have a slower time to IVF administration but equivocal use of sepsis recognition tools compared to patients without chronic disease.

Objective The objective of this study was to investigate the relationship between exhaled end-tidal carbon dioxide (ETCO2) and serum lactate via nasal capnography and to assess the ability of ETCO2 to predict disease severity in children with suspected sepsis in a pediatric emergency department. Methods This prospective study included patients (≥ 30 days to ≤21 years of age) who presented with suspected sepsis to a tertiary pediatric emergency department. Pearson correlation coefficient was generated to measure the linear relationship between ETCO2 and lactate. Receiver operating characteristic curves (ROC) were generated to assess the performance of ETCO2 to predict a lactate ≥2 mmol/L and severe disease. Severe disease was defined as severe sepsis and septic shock. Results From November 1, 2018 to March 31, 2020, 105 emergency department patients underwent evaluation for suspected sepsis. Sixty-nine patients met the inclusion criteria for the study. There was an inverse relationship between ETCO2 and lactate with a correlation coefficient of −0.34 (p = .005). Severe disease had lower ETCO2 (32 ± 6 mmHg, p Conclusions We observed a significant inverse relationship between ETCO2 and lactate in children presenting with suspected sepsis. A lower ETCO2 was predictive of severe disease.

Background. Observation is necessary following racemic epinephrine (RE) for patients with croup. The ideal length of this observation period is unclear. Objective. To compare the rate of failed outpatient management utilizing different observation times after RE administration for croup. Methods. We performed a retrospective chart review of children with croup who required RE. Failure of treatment was defined as requiring a second RE treatment and/or returning to the pediatric emergency department for croup symptoms within 24 hours of discharge. Results. The primary analysis considered patients observed between 2.1 and 3 hours compared with those observed for 3.1 to 4 hours. The patients in the 2.1- to 3-hour group had a higher rate of treatment failure (16.7% vs 7.1%, OR = 2.44, P < .01). Conclusions. Patients requiring RE for croup are more likely to have treatment failure if observed for between 2.1 and 3 hours as opposed to 3.1 to 4 hours.

An 8-year-old boy presented to the emergency department with swelling and pain of his left knee and calf for approximately 1 week. His examination was significant for moderate knee effusion and swelling of the posterior calf with erythema and warmth of the affected areas. An ultrasound obtained at an outside hospital showed a large heterogeneous mass in the gastrocnemius, and a magnetic resonance imaging revealed a large, heterogeneous, rim-enhancing collection in the medial head of the left gastrocnemius muscle with surrounding myositis involving the gastrocnemius muscle. The child was taken to the operating room by the orthopedic team for drainage and irrigation of the knee effusion and of the collection in the gastrocnemius. The diagnosis of Lyme pseudothrombophlebitis was made through Lyme serology testing of aspirated fluid. He improved after this drainage but required a prolonged antibiotic course.

Key Points Question What are the mechanisms, risk factors, and outcomes associated with acute kidney injury (AKI) during pediatric diabetic ketoacidosis (DKA)? Findings In this cohort study using data from 1359 DKA episodes in a large, multicenter, prospective study of fluid treatment during DKA, AKI occurred in 43% of episodes and was associated with greater acidosis and greater circulatory volume depletion. Children who had AKI were more likely to have subtle cognitive impairment during DKA and lower IQ at longer-term follow-up. Meaning These findings suggest that AKI is frequent in pediatric DKA and there is a pattern of multiorgan dysfunction during childhood DKA with the possibility of common pathophysiologic mechanisms., This cohort study examines the mechanisms, risk factors, and outcomes associated with acute kidney injury during pediatric diabetic ketoacidosis., Importance Acute kidney injury (AKI) occurs commonly during diabetic ketoacidosis (DKA) in children, but the underlying mechanisms and associations are unclear. Objective To investigate risk factors for AKI and its association with neurocognitive outcomes in pediatric DKA. Design, Setting, and Participants This cohort study was a secondary analysis of data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in DKA Study, a prospective, multicenter, randomized clinical trial comparing fluid protocols for pediatric DKA in 13 US hospitals. Included DKA episodes occurred among children age younger than 18 years with blood glucose 300 mg/dL or greater and venous pH less than 7.25 or serum bicarbonate level less than 15 mEq/L. Exposures DKA requiring intravenous insulin therapy. Main Outcomes and Measures AKI occurrence and stage were assessed using serum creatinine measurements using Kidney Disease: Improving Global Outcomes criteria. DKA episodes with and without AKI were compared using univariable and multivariable methods, exploring associated factors. Results Among 1359 DKA episodes (mean [SD] patient age, 11.6 [4.1] years; 727 [53.5%] girls; 651 patients [47.9%] with new-onset diabetes), AKI occurred in 584 episodes (43%; 95% CI, 40%-46%). A total of 252 AKI events (43%; 95% CI, 39%-47%) were stage 2 or 3. Multivariable analyses identified older age (adjusted odds ratio [AOR] per 1 year, 1.05; 95% CI, 1.00-1.09; P = .03), higher initial serum urea nitrogen (AOR per 1 mg/dL increase, 1.14; 95% CI, 1.11-1.18; P

BACKGROUND:Diabetic ketoacidosis in children may cause brain injuries ranging from mild to severe. Whether intravenous fluids contribute to these injuries has been debated for decades. METHODS:We conducted a 13-center, randomized, controlled trial that examined the effects of the rate of administration and the sodium chloride content of intravenous fluids on neurologic outcomes in children with diabetic ketoacidosis. Children were randomly assigned to one of four treatment groups in a 2-by-2 factorial design (0.9% or 0.45% sodium chloride content and rapid or slow rate of administration). The primary outcome was a decline in mental status (two consecutive Glasgow Coma Scale scores of

BACKGROUND Unsuccessful lumbar puncture (LP) attempts may lead to epidural hematoma (EH) formation within the spinal canal at the site of needle insertion, which can affect subsequent attempts. We aimed to determine the rate of EH formation after infant LP using bedside ultrasound (US). Furthermore, we aimed to correlate both perceived trauma during LP and cerebral spinal fluid (CSF) red blood cell (RBC) counts with EH formation. METHODS We enrolled infants younger than 6 months who underwent LP in the emergency department. The primary investigator performed a bedside US of the lumbar spine, which was reviewed and interpreted by a pediatric radiologist. Treating clinicians performed the procedure and were asked to classify each attempt as "traumatic" or "atraumatic." Cerebral spinal fluid RBC counts were recorded. RESULTS Thirty-one percent of patients had evidence of post-LP EH, 17% of which completely effaced the thecal sac. Forty percent of patients with at least 1 traumatic attempt had evidence of EH, whereas 25% without reported trauma showed EH (P = 0.17). Patients with EH had a median CSF RBC cell count of 186 cells/mm (range, 0-239,525) compared with 5 cells/mm (range, 0-3429) in patients without evidence of EH (P = 0.008). CONCLUSIONS Epidural hematomas are frequent after LP. Perceived trauma during LP and CSF RBC counts are not adequate predictors of EH formation. Point-of-care US may be a valuable adjunct to help guide subsequent needle insertions sites for repeat attempts after an unsuccessful LP.

Practitioners of procedural sedation and analgesia for children in an emergency department setting must balance the needs of individual patients, including safety and efficacy, with the needs of the department as a whole, including efficiency and appropriate use of resources. Individual patient needs will vary depending on the age and developmental stage of the patient, the anticipated level of pain and distress, the degree of immobility required, and the duration of the procedure. The ability to accurately predict the need for sedation, the level of sedation and degree of analgesia required for patient comfort, and the best sedative agent to accomplish these goals without undesirable consequences is a skill that requires knowledge and experience. This review presents 6 case scenarios illustrating various sedation options, from an evidence-based perspective whenever possible, for common pediatric presenting complaints.

Study Objective: We characterize repeat pediatric emergency department visits and determine the cause for such visits as an indicator of potential need for quality improvement. We hypothesized that most repeat ED visits resulting in hospitalization do not represent medical errors. Methods: The study was performed at a large, tertiary care, academic children's hospital. Patients who returned to the ED within 72 hours of a previous visit were identified by computerized registration data. The charts of these patients were then reviewed by a member of the ED medical staff to identify factors from the initial visit that contributed to the return visit. A multidisciplinary committee then reviewed each case until consensus was achieved regarding the cause for the repeat visit. In this study, we analyzed the quality improvement decisions from a 12-month period. Results: Over a 12-month period, during which there were a total of 51,195 visits, 285 (0.56%) patients were hospitalized after a repeat visit. The repeat visit was determined to be unrelated to the first visit in 12 (4.2%) patients. In 12 (4.2%) cases, the cause for repeat visit and hospitalization could not be determined. This resulted in a total of 261 patients for analysis. In 234 (90.0%) patients, the return visit was determined to be a result of the progression of illness (no medical error). Ten (3.8%) patients had a missed diagnosis, whereas 2 (0.8%) patients had errors in their treatment (likely medical error). An incomplete workup was cited in 7 (2.7%) patients (potential medical error). Parenting factors (refusing admission, not filling prescriptions, not giving prescribed medications) were noted in 5 (1.9%) cases. Three (1.1%) patients did not follow up with appropriate subspecialists. Conclusion: The overall rate of repeat visits resulting in hospitalization is small. In the majority of these cases (90.0%), the ED evaluation was appropriate and the admission was for progression of the patient's illness. Given the small number of patients and the infrequency of missed diagnoses, this may not be an efficient method for assessing ED performance. [DePiero AD, Ochsenschlager DW, Chamberlain JM.

Background Out-of-hospital emergency care is at an early stage of development in Armenia, with the current emergency medical services (EMS) system having emergency physicians (EPs) work on ambulances along with nurses. While efforts are underway by the Ministry of Health and other organizations to reform the EMS system, little data exists on the status of pediatric emergency care (PEC) in the country. We designed this study to evaluate the knowledge and attitudes of out-of-hospital emergency physicians in pediatric rapid assessment and resuscitation, and identify areas for PEC improvement. Methods We distributed an anonymous, self-administered Knowledge and Attitudes survey to a convenience sample of out-of-hospital EPs in the capital, Yerevan, from August to September 2012. Results With a response rate of 80%, the majority (89.7%) of respondents failed a 10-question knowledge test (with a pre-defined passing score of ≥7) with a mean score of 4.17 ± 1.99 SD. Answers regarding the relationship between pediatric cardiac arrest and respiratory issues, compression-to-ventilation ratio in neonates, definition of hypotension, and recognition of shock were most frequently incorrect. None of the participants had attended pediatric-specific continuing medical education (CME) activities within the preceding 5 years. χ2 analysis demonstrated no statistically significant association between physician age, length of EMS experience, type of ambulance (general vs. resuscitation/critical care), or CME attendance and pass/fail status. The majority of participants agreed that PEC education in Armenia needs improvement (98%), that there is a need for pediatric-specific CME (98%), and that national out-of-hospital PEC guidelines would increase PEC safety, efficiency, and effectiveness (96%). Conclusions Out-of-hospital emergency physicians in Yerevan, Armenia are deficient in pediatric-specific emergency assessment and resuscitation knowledge and training, but express a clear desire for improvement. There is a need to support additional PEC training and CME within the EMS system in Armenia.

The Emergency Severity Index version 4 (ESI v.4) is the most recently implemented 5-level triage system. The validity and reliability of this triage tool in the pediatric population have not been extensively established. The goals of this study were to assess the validity of ESI v.4 in predicting hospital admission, emergency department (ED) length of stay (LOS), and number of resources utilized, as well as its reliability in a prospective cohort of pediatric patients.The first arm of the study was a retrospective chart review of 780 pediatric patients presenting to a pediatric ED to determine the validity of ESI v.4. Abstracted data included acuity level assigned by the triage nurse using ESI v.4 algorithm, disposition (admission vs discharge), LOS, and number of resources utilized in the ED. To analyze the validity of ESI v.4, patients were divided into 2 groups for comparison: higher-acuity patients (ESI levels 1, 2, and 3) and lower-acuity patients (ESI levels 4 and 5). Pearson χ analysis was performed for categorical variables. For continuous variables, we conducted a comparison of means based on parametric distribution of variables. The second arm was a prospective cohort study to determine the interrater reliability of ESI v.4 among and between pediatric triage (PT) nurses and pediatric emergency medicine (PEM) physicians. Three raters (2 PT nurses and 1 PEM physician) independently assigned triage scores to 100 patients; k and interclass correlation coefficient were calculated among PT nurses and between the primary PT nurses and physicians.In the validity arm, the distribution of ESI score levels among the 780 cases are as follows: ESI 1: 2 (0.25%); ESI 2: 73 (9.4%); ESI 3: 289 (37%); ESI 4: 251 (32%); and ESI 5: 165 (21%). Hospital admission rates by ESI level were 1: 100%, 2: 42%, 3: 14.9%, 4: 1.2%, and 5: 0.6%. The admission rate of the higher-acuity group (76/364, 21%) was significantly greater than the lower-acuity group (4/415, 0.96%), P0.001. The mean ED LOS (in minutes) for the higher-acuity group was 257 (SD, 132) versus 143 (SD, 81) in the lower-acuity group, P0.001. The higher-acuity group also had significantly greater use of resources than the lower-acuity group, P0.001. The percentage of low-acuity patients receiving no resources was 54%, compared with only 26% in the higher-acuity group. Conversely, a greater percentage of higher-acuity patients utilized 2 or more resources than the lower-acuity cohorts, 43% vs 12%, respectively, P0.001. In the prospective reliability arm of the study, 15 PT nurses and 8 PEM attending physicians participated in the study; k among nurses was 0.92 and between the primary triage nurses and physicians was 0.78, P0.001. The intraclass correlation coefficient was 0.96 for PT nurses and 0.91 between the primary triage nurse and physicians, P0.001.Emergency Severity Index v.4 is a valid predictor of hospital admission, ED LOS, and resource utilization in the pediatric ED population. It is a reliable pediatric triage instrument with high agreement among PT nurses and between PT nurses and PEM physicians.

Background. Competence in basic orthopedic assessment and interpretation of radiographs is important for pediatricians because appropriate initial management of fractures can expedite therapy and minimize morbidity. However, requirements for training in orthopedics and radiology are poorly defined in pediatric residency programs. Objective. To assess the ability of pediatric residents to recognize and to manage appropriately pediatric fractures. Methods. This study involved administration of a case-based questionnaire with radiographs to volunteer categorical pediatric residents in 3 geographically diverse training programs. The diagnosis and management of 8 orthopedic complaints were evaluated. Responses were scored according to the number of features identified accurately, including the presence or absence of a fracture. Residents who were able to identify a fracture were assessed with respect to their ability to classify the fracture and to provide initial management. The study was pretested with a group of pediatric emergency medicine attending physicians, to establish the suitability of the cases. Results. Among the 3 residency sites, 102 of 190 eligible pediatric residents (53.7%) participated, yielding 95 completed questionnaires. The mean number of cases in which a resident correctly answered the question, “Is a fracture present?” and correctly identified the fractured bone (if a fracture was present) was 6.5 ± 1.2 of 8 cases (81.6%; 95% confidence interval: 78.5–84.7%). The diagnostic accuracy of Salter-Harris classification in cases in which such fractures were present was 40.9%. The mean score of correctly identified features for the resident group was 38.5 ± 9.4, of a possible 64 points (proportion correct: 60.1%; 95% confidence interval: 57.2-63%). There was a small but significant difference in mean correct responses between first-year residents (proportion correct: 55.4%; 95% confidence interval: 50.8- 60.3%) and third-year residents (proportion correct: 65.1%; 95% confidence interval: 60.7-69.5%). There was no association between the proportion of correct responses and whether or not residents had taken radiology or orthopedics elective courses in medical school. Overall, 43% of cases were both identified and managed correctly by the pediatric residents. Conclusions. For residents from the participating training programs, skills in recognizing and managing pediatric fractures were suboptimal. Additional review of training requirements is necessary to identify more clearly areas of improvement for current curricula.

We describe two patients with clinical and cytogenetic findings consistent with DiGeorge/velocardiofacial syndrome who had recurrent cytopenias at presentation. Our observations suggest that recurrent cytopenias may be part of the clinical spectrum of deletion 22q11.2. We also suggest that the diagnosis of DG/VCF syndrome be considered in patients with unexplained recurrent immune cytopenias in association with cardiac lesions, subtle craniofacial dysmorphisms, and/or learning or behavioral impairments.
