Foreign bodies lodged in the gastrointestinal tract can cause issues such as obstruction, perforation, and fistulae. Radiographic imaging can often locate most foreign bodies; however, radiolucent objects may be missed. Ultrasound is an alternative imaging modality that can be used to locate and track foreign objects as they pass through the bowel. The objective of this study was to characterize the sonographic appearance of various ingested foreign bodies of varying characteristics in an ex vivo gastrointestinal tract segment.METHODSA GE Logiq 9 ultrasound machine with a linear transducer at a frequency of 15 MHz was used to examine various ingested foreign bodies placed in a segment of pig intestinal tract.RESULTSImaged objects varied in visual appearance from echogenicity, texture, size, and shape; acoustic shadows and reverberation artifacts cast were particularly distinguishing characteristics.CONCLUSIONSUltrasound evaluation to assess foreign body ingestion in the pediatric population may provide a useful alternative or supportive imaging modality in confirming the location and real-time tracking of the ingested item. This may be especially useful for objects of varying radiodensities that cannot always be reliably seen in traditional radiographs.","PeriodicalId":19996,"journal":{"name":"Pediatric emergency care","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was from March 11, 2020, to May 11, 2023, during the COVID-19 pandemic. Patients were included if they were infants, 1 year or less, had a fever, and had a COVID-19 polymerase chain reaction test 1 week before or after presentation to the emergency department (ED) or hospital. We compared outcomes of bacteremia and a UTI in those with COVID-19 and those without COVID-19. Propensity matching was done to account for the confounders of age, gender, race, immune disorders, genitourinary abnormalities, preterm birth, and circumcision.RESULTSInfants who were positive for COVID-19 were at a reduced risk of UTI and bacteremia.

This study was designed to examine variability in offering IPV universal education to adult caregivers across patient race within an urban pediatric ED and to explore provider attitudes regarding the role of race in this process.METHODSWe conducted a mixed-methods study using quantitative data on rates of offering adult caregivers IPV universal education and rates of missing documentation for when IPV universal education was not offered to adult caregivers from January 2016 to December 2020. Analyses compared both rates by patient race listed in the electronic health record. We also conducted semistructured interviews with ED providers, which were qualitatively analyzed for common themes.RESULTSCaregivers of Black patients were both more likely to have received IPV universal education compared with caregivers of White patients (31.1% vs 27.3%, P < 0.05) and more likely to lack a documented reason for not offering than caregivers of White patients (70.4% vs 53.9%, P < 0.05). Our semistructured interviews with nurses, nurse practitioners, and physicians in the pediatric ED were able to ascertain specific racial biases that may influence these disparities.CONCLUSIONSOur study showed that racial disparities exist in both offering IPV universal education and documentation deferral in our pediatric ED. Combined analysis of our quantitative and qualitative data shows the importance of identifying biases that cause health disparities and increasing diversity among healthcare providers. The results of this study can be used to inform new methodologies for healthcare providers to address their personal biases and ensure that all caregivers visiting the ED are offered IPV support resources.","PeriodicalId":19996,"journal":{"name":"Pediatric emergency care","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized pediatric upper extremity (UE) fracture patterns and injury severity scores (ISS) differ between ORV types.METHODSThe authors' home-state trauma repository identified 157 pediatric patients aged 0 to 17 years with UE fractures after ORV accidents during 2011-2021. ORV injuries, fracture type, and procedures were identified using International Classification of Diseases, 9th Revision and 10th Revision coding followed by manual chart review or phone calls. We identified specific ORV type, driver/passenger status, and restraint use to compare differences between fracture characteristics, number of surgeries, and ISS. Groups were compared for differences at P < 0.05 significance.RESULTSAmong 157 ORV injuries, 75 resulted from ATVs (48%), 50 SXSs (32%), and 32 from all other vehicles (20%). Average age was 12 years, and 49% (n = 77) required surgery. SXS injuries had significantly higher open fracture rates (42%, n = 21) compared with ATVs (7%, n = 5) and all other ORV types (16%, n = 5; P < 0.0001). Seventy percent of fractures (n = 35) sustained after SXS accidents required surgery compared with 41% (n = 31) for ATVs and 34% (n = 11) for all other ORV types (P < 0.001). SXS drivers had 71% left-sided injuries, whereas 85% passengers had right-sided injuries (P < 0.0001). Patients younger than 13 years (n = 73) had significantly higher surgery rates (59%) compared with 40% for those 13 years and older (n = 84; P = 0.02). There were no significant differences in mean ± SD ISS between ATV (8 ± 6), SXS (8 ± 6), and other vehicles (7 ± 4; P = 0.34).CONCLUSIONSUE fractures caused by SXS were more likely to be open and require surgery compared with ATVs and other ORVs. SXS drivers were more likely to sustain left-sided injuries, whereas passengers had significantly higher right-sided injuries. Patients younger than 13 years were more likely to require surgery compared with teenagers.","PeriodicalId":19996,"journal":{"name":"Pediatric emergency care","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were collected through CC monitor device and video review. Data were analyzed in \"CC segments\" (periods of CC by individual providers). CC segments were coded \"yes\" or \"no\" for stepstool use based on video review. Univariate analyses of CC rate and depth between stepstool use and hand positions were performed through nonparametric testing, stratified by age category.RESULTSForty-two patients received 566 minutes of CC. Overall, American Heart Association (AHA)-compliant (rate and depth) CPR was achieved in 10% of CC segments for children <1 year and only 6% in children >1 year. A stepstool was used in 73% of CC segments in children <1 year and 88% in children >1 year. In children >1 year, stepstool use was associated with deeper CCs (P < 0.001) and a more compliant CC rate (P < 0.01). In children >1 year, 7% of those with a stepstool in use achieved AHA compliance, compared to those without a stepstool, where none achieved AHA compliance.CONCLUSIONSIn children >1 year, stepstool use resulted in greater CC depth and more AHA-compliant CC rate. No CC segments in children >1 year achieved AHA compliance without a stepstool. These data support uniform stepstool use during pediatric CPR in children >1 year of age.","PeriodicalId":19996,"journal":{"name":"Pediatric emergency care","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to determine the association between a modified National Emergency Department Overcrowding Score (mNEDOCS) and established ED metrics in a large academic tertiary care pediatric ED.METHODSNEDOCS was modified to increase applicability in the pediatric setting by including the number of patients in resuscitation rooms instead of a number of patients on ventilators. Patient characteristics, ED disposition, ED length of stay (LOS), rate of left without being seen (LWBS), hospital LOS (HLOS), ED returns within 72 hours, and mNEDOCS were acquired retrospectively for every ED encounter in 2016-2019 using the electronic health record. Descriptive statistics, Spearman correlation, and multivariate analyses were calculated to evaluate the association between specific ED metrics and mNEDOCS.RESULTSModified NEDOCS positively correlated with ED LOS, LWBS, and rate of 72-hour return visits. A negative correlation was found between mNEDOCS and HLOS. When controlling for select covariates, the odds of LWBS doubled with each increase in mNEDOCS category (odds ratio, 2.03; 95% confidence interval [CI], 2.00-2.06), ED LOS was associated with an increase of 27 minutes as mNEDOCS category increased (β = 26.80; 95% CI, 26.44-27.16), and the odds of 72-hour return visits increased by 6% when mNEDOCS increased by one category (odds ratio, 1.06; 95% CI, 1.05-1.07). Hospital LOS was associated with a 100-minute decrease per increase in mNEDOCS category (β = -99.85; 95% CI, -180.68 to -18.48) when controlling for covariates.CONCLUSIONModified NEDOCS is positively associated with ED LOS, LWBS, and 72-hour return visits, consistent with adult data. Further investigation is needed to elucidate the association between mNEDOCS and HLOS.
