We aimed to early identify independent risk factors of BD and their predictive performance in out-of-hospital cardiac arrest (OHCA) survivors. Methods: This retrospective observational study included adult OHCA survivors from May 2018 to February 2021. Independent risk factors for progression to BD were identified by performing multivariate logistic regression analysis, including clinical, laboratory, biological parameters and prognostic factors, obtained within 6 h after ROSC. Neuron-specific enolase (NSE) level were categorized into quartile. The primary outcome was BD occurrence. Results: Overall, 108 patients were included in this analysis, 31 (29%) of whom had BD. In multivariate logistic regression analysis, initial serum NSE levels in the fourth quartile compared to the first quartile (odds ratio [OR], 88.5; 95% confidence interval [CI]: 7.0–1113.6) and absence of pupil light reflex (PLR) (OR, 40.3; 95% CI: 3.8–430.3) were independently associated with BD. According to the receiver operating characteristic curve analysis, initial serum NSE levels and PLR showed good-to-excellent and fair-to-good prognostic performance, respectively (area under the curve [AUC], 0.90; 95% CI: 0.83–0.95 vs. 0.81; 95% CI: 0.72–0.88). Additionally, the combination of both the risk factors (AUC, 0.96; 95% CI: 0.90–0.99) showed significantly higher predictive performance for BD than when using them individually (P = 0.04 and P < 0.01, respectively). Conclusion: High levels of initial serum NSE and PLR obtained within 6 h after ROSC may help early predict progression to BD in OHCA survivors. A large prospective multicenter study should be conducted to confirm these results.

    查看更多>>摘要：? 2022 Elsevier Inc.Purpose: Controversy exists regarding the closed treatment of distal radius fractures. Circumferential casting of acute distal radius fractures has been shown to be safe in children, however, little research has demonstrated its safety in adults. The purpose of this study was to assess the risk of complications associated with casting acute distal radius fractures in adult patients. Methods: Patients with a distal radius fracture treated by a single hand surgeon at a level 1 trauma center were retrospectively reviewed over a 3-year period. Patients were evaluated in the emergency room and were provisionally immobilized either with short-arm fiberglass casts or with splints. Patients were followed for a minimum of 4 weeks. Complication rates associated with casting were recorded, including rates of compartment syndrome and acute carpal tunnel syndrome. Results: Eighty-one patients were included in this study. A total of 30 patients met inclusion criteria for placement of a short arm cast in the Emergency Department. Mean patient age was 63.2 years. The majority of patients sustained their injuries from a ground level fall. A minority of patients had radiographic evidence of intra-articular extension or underwent a reduction prior to casting. There were no patients who developed compartment syndrome or acute carpal tunnel syndrome as a result from the casting. The majority of patients did not require a cast change for at least 4 weeks. None of our patients went on to surgery. Conclusion: There were no major complications associated with casting of acute, low energy distal radius fractures in this series of 30 adult patients. While further studies with larger numbers of patients are necessary to establish safety of casting, this study suggests that casting may be a safe and effective treatment for low-energy distal radius fractures in adult patients presenting with a normal neurovascular exam. Type of study/level of evidence: Retrospective comparative study, Level III.

    查看更多>>摘要：? 2022 Elsevier Inc.Study objective: To determine the analgesic efficacy of TENS treatment in patients with renal colic in the emergency department (ED). Methods: This double-blind, randomized controlled trial was conducted in a tertiary care ED. Patients with a definitive diagnosis of renal colic were assigned (1:1) as randomized to receive the real TENS with frequency 100 Hz, pulse width 200 microseconds, voltage 2 mA, or placebo with sham TENS. Pain intensity was measured using visual analog scales (VAS) at baseline, after 15 and 30th minutes. Results: A total of 100 patients were included in the final analysis: 50 patients treated with real TENS and 50 patients treated with sham TENS. VAS scores in both groups were similar at baseline. The mean reduction in VAS score at 15 min was 33.3 ± 17.6 (95% Confidence interval (CI): 28.3 to 38.3) for the real TENS group and 14.9 ± 11.6 (95% CI 11.6 to 18.2) for the sham TENS group (mean difference: 18.4 (95% CI: 12.5 to 24.4, P < 0.0001). The mean reduction in VAS score at 30 min was 63.7 ± 21.1 (95% CI: 57.7 to 69.7) for the real TENS group and 14.9 ± 16.2 (95% CI: 19.5 to 10.3) for the sham TENS group (mean difference: 48.8, 95% CI: 41.4 to 56.3, P < 0.0001). Four patients (8%) in the real TENS group and 24 patients (48%) in the sham TENS group required the rescue medication after 30th minutes. Conclusions: TENS is effective for acute pain treatment in renal colic patients in the ED. TENS therapy could be a treatment option for renal colic.

    查看更多>>摘要：? 2022Background: There exists a need for prognostic tools for the early identification of COVID-19 patients requiring intensive care unit (ICU) admission and mortality. Here we investigated the association between a clinical (initial prehospital shock index (SI)) and biological (initial prehospital lactatemia) tool and the ICU admission and 30-day mortality among COVID-19 patients cared for in the prehospital setting. Methods: We retrospectively analysed COVID-19 patients initially cared for by a Paris Fire Brigade advanced (ALS) or basic life support (BLS) team in the prehospital setting between 2020, March 08th and 2020, May 30th. We assessed the association between prehospital SI and prehospital lactatemia and ICU admission and mortality using logistic regression model analysis after propensity score matching with Inverse Probability Treatment Weighting (IPTW) method. Covariates included in the IPTW propensity analysis were: age, sex, body mass index (BMI), initial respiratory rate (iRR), initial pulse oximetry without (SpO2i) and with oxygen supplementation (SpO2i.O2), initial Glasgow coma scale (GCSi) value, initial prehospital SI and initial prehospital lactatemia. Results: We analysed 410 consecutive COVID-19 patients [254 males (62%); mean age, 64 ± 18 years]. Fifty-seven patients (14%) deceased on the scene, of whom 41 (72%) were male and were significantly older (71 ± 12 years vs. 64 ± 19 years; P 〈10?3). Fifty-three patients (15%) were admitted in ICU and 39 patients (11%) were deceased on day-30. The mean prehospital SI value was 1.5 ± 0.4 and the mean prehospital lactatemia was 2.0 ± 1.7 mmol.l?1. Multivariate logistic regression analysis on matched population after IPTW propensity analysis reported a significant association between ICU admission and age (adjusted Odd-Ratio (aOR), 0.90; 95% confidence interval (95%CI): 0.93–0.98;p = 10?3), SpO2i.O2 (aOR, 1.10; 95%CI: 1.02–1.20;p = 0.002) and BMI (aOR, 1.09; 95% CI: 1.03–1.16;p = 0.02). 30-day mortality was significantly associated with SpO2i.O2 (aOR, 0.92; 95% CI: 0.87–0.98;p = 0.01 P < 10?3) and GCSi (aOR, 0.90; 95% CI: 0.82–0.99;p = 0.04). Neither prehospital SI nor prehospital lactatemia were associated with ICU admission and 30-day mortality. Conclusion: Neither prehospital initial SI nor lactatemia were associated with ICU admission and 30-day mortality among COVID-19 patients initially cared for by a Paris Fire Brigade BLS or ALS team. Further prospective studies are needed to confirm these preliminary results.

    查看更多>>摘要：? 2022 Elsevier Inc.Objective: New York City (NYC) is home to the largest public healthcare system in the United States and was an early epicenter of coronavirus disease 2019 (COVID-19) infections. This system serves as the safety net for underserved and marginalized communities disproportionately affected by the pandemic. Prior studies reported substantial declines in pediatric emergency department (ED) volume during the initial pandemic surge, but few describe the ongoing impact of COVID-19 throughout the year. We evaluated the characteristics of pediatric ED visits to NYC public hospitals during the pandemic lockdown and reopening periods of 2020 compared to the prior year. Methods: Retrospective cross-sectional analysis of pediatric ED visits from 11 NYC public hospitals from January 2019–December 2020. Visit demographics, throughput times, and diagnosis information during the early (3/7/20–6/7/20) and late (6/8/20–12/31/20) pandemic periods coinciding with the New York State of emergency declaration (3/7/20) and the first reopening date (6/7/20) were compared to similar time periods in 2019. Findings were correlated with key pandemic shutdown and reopening events. Results: There was a 47% decrease in ED volume in 2020 compared to 2019 (125,649 versus 238,024 visits). After reopening orders began in June 2020, volumes increased but peaked at <60% of 2019 volumes. Admission rates, triage acuity, and risk of presenting with a serious medical illness were significantly higher in 2020 versus 2019 (P < 0.001). Time-to-provider times decreased however provider-to-disposition times increased during the pandemic (P < 0.001). Infectious and asthma diagnoses declined >70% during the pandemic in contrast to the year prior. After reopening periods began, penetrating traumatic injuries significantly increased compared to 2019 [+34%, Relative Risk: 3.2 (2.6, 3.8)]. Conclusions: NYC public hospitals experienced a sharp decrease in pediatric volume but an increase in patient acuity during both the initial pandemic surge and through the reopening periods. As COVID-19 variants emerge, the threat of the current pandemic expanding remains. Understanding its influence on pediatric ED utilization can optimize resource allocation and ensure equitable care for future surge events.

    High risk and low prevalence diseases: Ovarian torsion

    Bridwell R.E.Koyfman A.Long B.
    6页
    查看更多>>摘要：? 2022Introduction: Ovarian torsion is a rare, frequently misdiagnosed condition that carries with it a high rate of morbidity. Objective: This review highlights the pearls and pitfalls of ovarian torsion, including presentation, evaluation, and management in the emergency department (ED) based on current evidence. Discussion: Ovarian torsion is one of the most common gynecological surgical emergencies and occurs with complete or partial rotation of the ovary along the supporting ligaments, obstructing vascular flow. Several risk factors include the presence of an ovarian mass or cyst. The most common population affected includes reproductive aged women, though cases also occur in premenarchal females, pregnant women, and postmenopausal women. Abdominal or pelvic pain is common but is not always sudden in onset or severe. Nausea and vomiting occur in 70%. Ultrasound can assist with diagnosis, but a normal ultrasound examination cannot exclude the diagnosis. Computed tomography with intravenous contrast can assist with diagnosis. Treatment includes emergent gynecologic consultation for surgical detorsion, along with symptomatic therapy in the ED. Conclusions: An understanding of ovarian torsion can assist emergency clinicians in diagnosing and managing this disease.

    查看更多>>摘要：? 2022 Elsevier Inc.Objectives: Emergency department (ED) hepatitis C virus (HCV) screening programs are proliferating, and it is unknown whether EDs are more effective than traditional community screening at promoting HCV follow-up care. The objective of this study was to investigate whether patients screened HCV seropositive (HCV+) in the ED are linked to care and retained in treatment more successfully than patients screened HCV+ in the community. Methods: A retrospective cohort study was performed including patients screened HCV+ at twelve screening facilities in New Orleans, LA from March 1, 2015 to July 31, 2017. Treatment outcomes, including retention and time to follow-up care, were assessed using the HCV continuum of care model. Results: ED patients (n = 3008) were significantly more likely to achieve RNA confirmation (aRR = 1.91, 95% CI = 1.54–2.37), initiate HCV therapy (aRR = 2.23 [1.76–2.83]), complete HCV therapy (aRR = 1.77 [1.40–2.24]), and achieve HCV functional cure (aRR = 2.80 [1.09–7.23]) compared to community-screened patients (n = 322). ED screening was associated with decreased likelihood of fibrosis staging (aRR = 0.65 [0.51–0.82]) and no difference in linkage to specialty care (aRR = 1.03 [0.69–1.53]). In time to follow up, RNA confirmation occurred at faster rates in the ED (aHR = 2.26 [1.86–2.72]), although these patients completed fibrosis staging at slower rates (aHR = 0.49 [0.38–0.63]) than community patients. Conclusions: Compared to community screening, HCV screening in the ED was associated with higher rates of disease confirmation, treatment initiation/completion, and cure. Our findings provide new evidence that EDs may be the most effective setting to screen patients for HCV to promote follow-up care.

    13页
    查看更多>>摘要：? 2022Introduction: Coronavirus disease of 2019 (COVID-19) has resulted in millions of cases worldwide. As the pandemic has progressed, the understanding of this disease has evolved. Objective: This is the second part in a series on COVID-19 updates providing a focused overview of the medical management of COVID-19 for emergency and critical care clinicians. Discussion: COVID-19, caused by Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), has resulted in significant morbidity and mortality worldwide. A variety of medical therapies have been introduced for use, including steroids, antivirals, interleukin-6 antagonists, monoclonal antibodies, and kinase inhibitors. These agents have each demonstrated utility in certain patient subsets. Prophylactic anticoagulation in admitted patients demonstrates improved outcomes. Further randomized data concerning aspirin in outpatients with COVID-19 are needed. Any beneficial impact of other therapies, such as colchicine, convalescent plasma, famotidine, ivermectin, and vitamins and minerals is not present in reliable medical literature. In addition, chloroquine and hydroxychloroquine are not recommended. Conclusion: This review provides a focused update of the medical management of COVID-19 for emergency and critical care clinicians to help improve care for these patients.

    查看更多>>摘要：? 2022Objectives: Biguanides and sulfonylureas are anti-hyperglycemic drugs commonly used in the United States. Poisoning with these drugs may lead to serious consequences. The diagnosis of biguanide and sulfonylurea poisoning is based on history, clinical manifestations, and laboratory studies. Methods: This study is a six-year retrospective cohort analysis based on the National Poison Data System. Clinical effects of 6183 biguanide and sulfonylurea exposures were identified using binary logistic regression. Results: The mean age of patients with biguanide and sulfonylurea exposure was 39.27 ± 28.91 and 28.91 ± 30.41 years, respectively. Sulfonylurea exposure is most commonly seen via unintentional exposure, while biguanide exposure frequently occurs as a result of intentional ingestion. Minor and moderate outcomes commonly developed following biguanide and sulfonylurea exposure, respectively. Sulfonylurea exposure was less likely to develop clinical effects abdominal pain, metabolic acidosis, diarrhea, nausea, vomiting, and elevated creatinine than patients ingesting biguanides. However, sulfonylurea exposure was more likely to cause dizziness or vertigo, tremor, drowsiness or lethargy, agitation, diaphoresis, and hypoglycemia. Conclusions: Our study is the first to use a wide range of national data to describe the clinical characteristics that differentiate the toxicologic exposure to biguanides and sulfonylureas. Sulfonylurea exposure is commonly seen via unintentional exposure, while metformin exposure is frequently seen via intentional exposure. Sulfonylurea toxicity is more likely to cause agitation, dizziness or vertigo, tremor, diaphoresis, and hypoglycemia, while metformin exposure induces abdominal pain, acidosis, diarrhea, nausea, vomiting, and elevated creatinine.

    Risk factors for trimethoprim and sulfamethoxazole-resistant Escherichia coli in emergency department patients with urinary tract infections

    Smalley C.M.Wang L.Campbell M.J.Wesolek J.L....
    5页
    查看更多>>摘要：? 2022 Elsevier Inc.Background: While trimethoprim-sulfamethoxazole (TMP-SMX) is recommended as one of the first-line empiric therapies for treatment of acute uncomplicated cystitis, institutions that observe resistance rates exceeding 20% for Escherichia coli (E. coli) should utilize alternative empiric antibiotic therapy per the Infectious Diseases Society of America (IDSA). Identifying risk factors associated with TMP-SMX resistance in E. coli may help guide empiric antibiotic prescribing for urinary tract infections (UTIs). Methods: This multicenter, retrospective study included adult patients who were discharged from 12 emergency departments (EDs) with a urine culture positive for E. coli between January 1, 2019 and December 31, 2019. Logistic regression was used to assess the relationship between potential risk factors and TMP-SMX resistance. The overall institutional antimicrobial resistance rates for E. coli were compared to the rates seen in the study population of ED urinary isolates. Results: Among 427 patients included from a randomized sample of 500 with a urine culture positive for E. coli, 107 (25.1%) were resistant to TMP-SMX. Three predictors of TMP-SMX resistance were identified: recurrent UTI (OR 2.27 [95% CI 1.27–3.99]), genitourinary abnormalities (OR 2.31 [95% CI 1.17–4.49]), and TMP-SMX use within 90 days (OR 8.77 [95% CI 3.19–28.12]). When the antibiotic susceptibilities for this ED cohort were compared to the institutional antibiogram, the TMP-SMX resistance rate was found to be higher in the ED population (25.1% vs 20%). Conclusions: TMP-SMX should likely be avoided as first-line therapy for UTI in patients who have recurrent UTIs, genitourinary abnormalities, or have previously received TMP-SMX within the past 90 days. The use of an ED-specific antibiogram should be considered for assessing local resistance rates in this population.
