Background
Quick Sequential Organ Failure Assessment (qSOFA) is a prognostic score for patients with sepsis.Objective
Our aim was to compare the area under the receiver operating curve (AUROC), sensitivity, specificity, and likelihood ratios of qSOFA vs. systemic inflammation response syndrome (SIRS) in predicting in-hospital mortality among emergency department (ED) patients with suspected infection admitted to intensive care units (ICUs).Methods
We conducted a retrospective cohort chart review study of ED patients admitted to an ICU with suspected infection from August 1, 2012 to February 28, 2015. We included all patients with body fluid cultures sampled either during their ED stay without antibiotic administration or within 24 h of antibiotics administered in the ED. Trained chart abstractors blinded to the study hypothesis double-entered data from each patient's electronic medical record including demographic characteristics, vital signs, laboratory study results, physical examination findings, and in-hospital mortality. We then calculated the AUROC, sensitivity, specificity, and likelihood ratios for qSOFA and SIRS for predicting in-hospital mortality.Results
Of 214 patients admitted to an ICU with presumed sepsis, 39 (18.2%) died during hospitalization. The AUROC value was 0.65 (95% confidence interval [CI] 0.56–0.74) for SIRS vs. 0.66 (95% CI 0.57–0.76) for qSOFA; 2+ qSOFA criteria predicted in-hospital mortality with 89.7% sensitivity, 27.4% specificity, 1.2 positive likelihood ratio, and 0.4 negative likelihood ratio.Conclusions
Among ED patients admitted to an ICU, the SIRS and qSOFA criteria had comparable prognostic value for predicting in-hospital mortality. These prognostic values are similar to those reported by the Sepsis-3 guidelines for ICU encounters. 相似文献2.

Study objective
We investigated seasonal prevalence of hyponatremia in the emergency department (ED).Design
A cross-sectional study using clinical chart review.Setting
University Hospital ED, with approximately 28 000 patient visits a year.Type of participants
We reviewed 15 049 patients, subdivided in 2 groups: the adult group consisting of 9822 patients aged between 18 and 64 years old and the elderly group consisting of 5227 patients aged over 65 years presenting to the ED between January 1st, 2014 and December 31st, 2015.Intervention
Emergency patients were evaluated for the presence of hyponatremia by clinical chart review.Measurements and main results
Hyponatremia was defined as a serum sodium level < 135 mmol/l. Mean monthly prevalence of hyponatremia was of 3.74 ± 0.5% in the adult group and it was significantly increased to 10.3 ± 0.7% in the elderly group (p < 0.05 vs adults). During the summer, hyponatremia prevalence was of 4.14 ± 0.2% in adult and markedly increased to 12.52 ± 0.7% (zenith) in elderly patients (p < 0.01 vs adult group; p < 0.05 vs other seasons in elderly group). In the elderly group, we reported a significant correlation between weather temperature and hyponatremia prevalence (r: 0.491; p < 0.05).Conclusion
We observed a major influence of climate on the prevalence of hyponatremia in the elderly in the ED. Decline in renal function, salt loss, reduced salt intake and increased water ingestion could all contribute to developing hyponatremia in elderly patients during the summer. These data could be useful for emergency physicians to prevent hot weather-induced hyponatremia in the elderly. 相似文献3.

Background
Hypoxemia increases the risk of intubation markedly. Such concerns are multiplied in the emergency department (ED) and during retrieval where patients may be unstable, preparation or preoxygenation time limited and the environment uncontrolled. Apneic oxygenation is a promising means of preventing hypoxemia in this setting.Aim
To test the hypothesis that apnoeic oxygenation reduces the incidence of hypoxemia during endotracheal intubation in the ED and during retrieval.Methods
We undertook a systematic review of six databases for all relevant studies published up to November 2016. Included studies evaluated apneic oxygenation during intubation in the ED and during retrieval. There were no exemptions based on study design. All studies were assessed for level of evidence and risk of bias. The Review Manager 5.3 software was used to perform meta-analysis of the pooled data.Results
Six trials and a total 1822 cases were included for analysis. The study found a significant reduction in the incidence of desaturation (RR = 0.76, p = 0.002) and critical desaturation (RR = 0.51, p = 0.01) when apneic oxygenation was implemented. There was also a significant improvement in first pass intubation success rate (RR = 1.09, p = 0.004).Conclusion
Apneic oxygenation may reduce patient hypoxemia during intubation performed in the ED and during retrieval. It also improves intubation first-pass success rate in this setting. 相似文献4.

Background
Recently a multispecialty, multinational task force convened to redefine the criteria for organ dysfunction, sepsis, severe sepsis, and septic shock. The study recommended the quick sequential organ failure assessment (qSOFA) score to identify sepsis patients. The qSOFA is felt to be the initial screen to prompt a more in-depth sepsis workup. This may be particularly true in resource-limited environments such as the prehospital arena.Objectives
The goal of this study was to identify whether emergency medical services (EMS) patients who met all three qSOFA criteria correlated with an emergency department (ED) identification of sepsis.Methods
This was a retrospective chart review of adult patients ≥ 18 years of age, meeting qSOFA criteria and presenting to the emergency department between 1/01/2014 and 6/30/2016. Subjects were identified through an electronic query of the EMS record repository.Results
72 subjects were included in the final analysis. Subjects in the septic group tended to be older with a mean age of 72 years vs 64 years. There was no observed discrepancy relating to gender. 48 of the subjects (67%) were identified as septic and 24 (33%) were identified as non-septic after review of the ED chart. This yielded a positive predictive value of the prehospital qSOFA as 66.67% (95% CI 55.8–77.6).Conclusions
EMS patients with positive qSOFA screens were more likely to be septic upon disposition to the ED. 相似文献5.

Background
Our objective was to compare in-hospital mortality among emergency department (ED) patients meeting trial-based criteria for septic shock based upon whether presenting with refractory hypotension (systolic blood pressure < 90 mm Hg after 1 L intravenous fluid bolus) versus hyperlactatemia (initial lactate ≥ 4 mmol/L).Methods
We conducted a retrospective cohort analysis by chart review of ED patients admitted to an intensive care unit with suspected infection during 1 August 2012–28 February 2015. We included all patients with body fluid cultures sampled either during their ED stay without antibiotic administration or within 24 h of antibiotic administration in the ED. We excluded patients not meeting criteria for either refractory hypotension or hyperlactatemia. Trained chart abstractors blinded to the study hypothesis double entered data from each patient's record including demographics, clinical data, treatments, and in-hospital mortality. We compared in-hospital mortality among patients with isolated refractory hypotension, isolated hyperlactatemia, or both. We also calculated odds ratios (ORs) via logistic regression for in-hospital mortality based on presence of refractory hypotension or hyperlactatemia.Results
Of 202 patients included in the analysis, 38 (18.8%) died during hospitalization. Mortality was 10.9% among 101 patients with isolated refractory hypotension, 24.4% among 41 patients with isolated hyperlactatemia, and 28.3% among 60 patients with both (p = 0.01). Logistic regression analyses yielded in-hospital mortality OR for refractory hypotension of 1.3 (95% CI 0.5–3.8) versus OR for hyperlactatemia of 2.9 (95% CI 1.2–7.4).Conclusions
Hyperlactatemia appears associated with higher in-hospital mortality compared to refractory hypotension among ED patients with septic shock. 相似文献6.

Background
Minimizing and preventing adverse events and medical errors in the emergency department (ED) is an ongoing area of quality improvement. Identifying these events remains challenging.Objective
To investigate the utility of tracking patients transferred to the ICU within 24 h of admission from the ED as a marker of preventable errors and adverse events.Methods
From November 2011 through June 2016, we prospectively collected data for all patients presenting to an urban, tertiary care academic ED. We utilized an automated electronic tracking system to identify ED patients who were admitted to a hospital ward and then transferred to the ICU within 24 h. Reviewers screened for possible error or adverse event and if discovered the case was referred to the departmental Quality Assurance (QA) committee for deliberations and consensus agreement.Results
Of 96,377 ward admissions, 921 (1%) patients were subsequently transferred to the ICU within 24 h of ED presentation. Of these 165 (19%) were then referred to the QA committee for review. Total rate of adverse events regardless of whether or not an error occurred was 2.1%, 19/921 (95% CI 1.4% to 3.0%). Medical error on the part of the ED was 2.2%, 20/921 (95% CI 1.5% to 3.1%) and ED Preventable Error in 1.1%, 10/921 (95% CI 0.6% to 1.8%).Conclusion
Tracking patients admitted to the hospital from the ED who are transferred to the ICU < 24 h after admission may be a valuable marker for adverse events and preventable errors in the ED. 相似文献7.

Background
Motor vehicle–related injuries (including off-road) are the leading cause of traumatic brain injury (TBI) and acute traumatic spinal cord injury in the United States.Objectives
To describe motocross-related head and spine injuries of adult patients presenting to an academic emergency department (ED).Methods
We performed an observational cohort study of adult ED patients evaluated for motocross-related injuries from 2010 through 2015. Electronic health records were reviewed and data extracted using a standardized review process.Results
A total of 145 motocross-related ED visits (143 unique patients) were included. Overall, 95.2% of patients were men with a median age of 25 years. Sixty-seven visits (46.2%) were associated with head or spine injuries. Forty-three visits (29.7%) were associated with head injuries, and 46 (31.7%) were associated with spine injuries. Among the 43 head injuries, 36 (83.7%) were concussions. Seven visits (16.3%) were associated with at least 1 head abnormality identified by computed tomography, including skull fracture (n = 2), subdural hematoma (n = 1), subarachnoid hemorrhage (n = 4), intraparenchymal hemorrhage (n = 3), and diffuse axonal injury (n = 3). Among the 46 spine injuries, 32 (69.6%) were acute spinal fractures. Seven patients (4.9%) had clinically significant and persistent neurologic injuries. One patient (0.7%) died, and 3 patients had severe TBIs.Conclusion
Adult patients evaluated in the ED after motocross trauma had high rates of head and spine injuries with considerable morbidity and mortality. Almost half had head or spine injuries (or both), with permanent impairment for nearly 5% and death for 0.7%. 相似文献8.

Objectives
This was a before and after study which sought to assess the impact of opening an ED short stay unit (ESSU) on the ED performance of poisoned patients.Methods
Data was collected from two groups of adult patients presenting to an ED with a tertiary referral inpatient Toxicology unit from the 2009 and 2012 calendar years, to assess the impact of the ESSU. The toxicology unit clinical database and hospital electronic medical records were interrogated for demographic, clinical and hospital flow details of presentations. The primary outcome was ED length of stay (LOS). Other outcomes included proportion of patients remaining in ED for their admission, 28 day re-presentations and hospital LOS.Results
During 2009, 795 patients met inclusion criteria, and during 2012, 762. The median LOS in ED was reduced from 8.5 h (IQR: 4.7–14 h) to 2.7 h (IQR: 1.6–4.6; p < 0.0001). The proportion of patients remaining in ED for their entire hospital stay was reduced from 515/795 (65%) to 56/762 (7.3%) [Absolute difference: 57%; 95% CI: 53 to 62%; p < 0.0001]. Total hospital LOS increased from 14.5 h (IQR: 8.4–21.8 h) to 16.7 h (IQR: 11.5–23; p < 0.0001), but there was a decrease in re-presentations with self-poisoning within 28 days from 6.9% in 2009 to 4.5% in 2012 (p < 0.038). There was no difference between disposition destination or toxins causing exposure between the two groups.Conclusions
The ESSU led to a significant improvement in ED performance of poisoned patients. It also potentially assisted in reducing ED overcrowding. 相似文献9.

Objectives
The American College of Emergency Physicians Geriatric Emergency Department (ED) Guidelines and the Center for Disease Control recommend that older adults be assessed for risk of falls. The standard ED assessment is a verbal query of fall risk factors, which may be inadequate. We hypothesized that the addition of a functional balance test endorsed by the Center for Disease Control Stop Elderly Accidents, Deaths, and Injuries Falls Prevention Guidelines, the 4-Stage Balance Test (4SBT), would improve the detection of patients at risk for falls.Methods
Prospective pilot study of a convenience sample of ambulatory adults 65 years and older in the ED. All participants received the standard nursing triage fall risk assessment. After patients were stabilized in their ED room, the 4SBT was administered.Results
The 58 participants had an average age of 74.1 years (range, 65-94), 40.0% were women, and 98% were community dwelling. Five (8.6%) presented to the ED for a fall-related chief complaint. The nursing triage screen identified 39.7% (n = 23) as at risk for falls, whereas the 4SBT identified 43% (n = 25). Combining triage questions with the 4SBT identified 60.3% (n = 35) as at high risk for falls, as compared with 39.7% (n = 23) with triage questions alone (P < .01). Ten (17%) of the patients at high risk by 4SBT and missed by triage questions were inpatients unaware that they were at risk for falls (new diagnoses).Conclusions
Incorporating a quick functional test of balance into the ED assessment for fall risk is feasible and significantly increases the detection of older adults at risk for falls. 相似文献10.

Background
We aimed to derive and validate a parsimonious and pragmatic clinical prediction rule using the concepts of Predisposition, Infection, Response, and Organ Dysfunction to predict in-hospital mortality; and to compare it with other prediction rules, as well as with conventional biomarkers for evaluating the mortality risk of patients with suspected sepsis in the emergency department (ED).Methods
We conducted a pragmatic cohort study with consecutive ED patients aged 18 or older with documented diagnostic codes of infection and two sets of blood culture ordered by physicians between 2010 and 2012 in a tertiary teaching hospital.Results
7011 and 12,110 patients were included in the derivation cohort and the validation cohort for the final analysis. There were 479 deaths (7%) in the derivation cohort and 1145 deaths (9%) in the validation cohort. Independent predictors of death were absence of Chills (odds ratio: 2.28, 95% confidence interval: 1.75–2.97), Hypothermia (2.12, 1.57–2.85), Anemia (2.45, 1.97–3.04), wide Red cell Distribution Width (RDW) (3.27, 2.63–4.05) and history of Malignancy (2.00, 1.63–2.46). This novel clinical prediction rule (CHARM) performed well for stratifying patients into mortality risk groups (sensitivity: 99.4%, negative predictive value 99.7%, receiver operating characteristic area 0.77). The CHARM score also outperformed the other scores or biomarkers such as PIRO, SIRS, MEDS, CURB-65, C-reactive protein, procalcitonin and lactate (all p < .05).Conclusions
In patients with suspected sepsis, this parsimonious and pragmatic model could be utilized to stratify the mortality risk of patients in the early stage of sepsis. 相似文献11.

Background
Antibiotics are overprescribed for abnormal urine tests including asymptomatic bacteriuria (AB), contributing to rising antimicrobial resistance rates. Pharmacists reviewed urine cultures daily from emergency department (ED) encounters to assess antibiotic appropriateness. We studied antibiotic prescribing practices and assessed compliance to national guidelines, correlations with urine analysis (UA) components, and opportunities for antimicrobial stewardship in the ED.Methods
This quality improvement project (QIP) was a prospective cohort study at a community hospital ED, with data collected from finalized urine cultures resulting October 30, 2014 through January 5, 2015. Analyses were conducted using Chi-squared and Fisher Exact tests and stepwise multiple logistic regression.Results
Urine cultures from 457 encounters were reviewed, of which 136 met the inclusion criteria as non-pregnant and asymptomatic for urinary tract infection (UTI). 43% of 136 patients were treated with antibiotics, for a total of 426 antibiotic days. Pharmacist interventions for these patients resulted in 122/426 (29%) of potential antibiotic days saved. Factors found to significantly increase the odds of antibiotic prescribing in asymptomatic patients included presence of leukocyte esterase (OR = 4.5, 95% CI: 1.2–17.2; p = 0.03) or nitrites (OR = 10.8, 95% CI: 1.7–68.1; p = 0.01) in the urine and age ≥ 75 (OR = 3.5, 95% CI: 1.2-9.6, p = 0.02).Discussion
Pharmacist intervention in discontinuing or modifying antibiotics for asymptomatic patients with urine cultures reduced unnecessary antibiotic exposure and was a first step in antimicrobial stewardship efforts in the ED. Future work includes limiting urine tests and subsequent antibiotic therapy for non-pregnant asymptomatic patients. 相似文献12.

Objective
The CHOKAI and STONE scores are prediction models for ureteral stones. The aims of the present study were to evaluate the diagnostic performance, to examine the optimal cut-off value, and to compare the diagnostic performance of each model.Methods
Patients who presented to our emergency department with renal colic were considered for this prospective study. We analyzed the predictive performance of both STONE and CHOKAI scores at their optimal cut-off values, using receiver operating characteristic (ROC) curve and area under the curve (AUC), as well as sensitivity, specificity, positive likelihood ratio (LR +), and negative likelihood ratio (LR ?) at the optimal cut-off value.Results
Of the 96 patients who met the inclusion criteria, 79 were definitively diagnosed with ureteral stones. All patients were of Japanese descent. The AUC of the CHOKAI score was 0.971 at an optimal cut-off value of 6, showing a sensitivity of 0.911, specificity of 0.941, LR + of 15.49, and LR ? of 0.094. The AUC of the STONE score was 0.873 at an optimal cut-off value of 8, showing a sensitivity of 0.823, specificity of 0.824, LR + of 4.662, and LR ? of 0.215. The AUC of the CHOKAI score was significantly higher than that of the STONE score (p = 0.010). Of the 73 patients with a CHOKAI score of ≥ 6, 98.6% had ureteral stones, and of the 68 patients with a STONE score of ≥ 8, 95.6% had ureteral stones.Conclusions
The simplified CHOKAI score is a useful tool to screen for ureteral stones in patients with renal colic. 相似文献13.

Study objectives
To compare diagnostic test ordering practices of NPs with those of physicians in the role of Provider in Triage (PIT).Methods
This was a secondary analysis of data from a prospective RCT of waiting room diagnostic testing, where 770 patients had diagnostic studies ordered from the waiting room. The primary outcome was the number of test categories ordered by provider type. Other outcomes included total tests ordered by the end of ED stay, and time in an ED bed. We compared variables between groups using t-test and chi-square, constructed logistic regression models for individual test categories, and univariate and multivariate negative binomial models.Results
Physicians ordered significantly more diagnostic test categories than NPs (1.75 vs. 1.54, p < 0.001). By the end of their ED stay, there was no significant difference in total test categories ordered between provider type: physician 2.67 vs. NP 2.53 (p = 0.08), using a nonbinomial model, incidence rate ratio (IRR) 1.07 (0.98–1.17). Patient time in an ED bed was not significantly different between physicians and NPs (NP 244 min, SD = 133, Physicians 248 min, SD = 152) difference 4 min (? 24.3–16.1) p = 0.688.Conclusion
NPs in the PIT role ordered slightly less diagnostic tests than attending physicians. This slight difference did not affect time spent in an ED bed. By the end of the ED stay, there was no significant difference in total test categories ordered between provider types. PIT staffing with NPs does not appear to be associated with excess test ordering or prolonged ED patient stays. 相似文献14.

Background
Patients with traumatic intracranial hemorrhage and mild traumatic brain injury (mTIH) receive broadly variable care which often includes transfer to a trauma center, neurosurgery consultation and ICU admission. However, there may be a low risk cohort of patients who can be managed without utilizing such significant resources.Objective
Describe mTIH patients who are at low risk of clinical or radiographic decompensation and can be safely managed in an ED observation unit (EDOU).Methods
Retrospective evaluation of patients age ≥ 16, GCS ≥ 13 with ICH on CT. Primary outcomes included clinical/neurologic deterioration, CT worsening or need for neurosurgery.Results
1185 consecutive patients were studied. 814 were admitted and 371 observed patients (OP) were monitored in the EDOU or discharged from the ED after a period of observation. None of the OP deteriorated clinically. 299 OP (81%) had a single lesion on CT; 72 had mixed lesions. 120 patients had isolated subarachnoid hemorrhage (iSAH) and they did uniformly well. Of the 119 OP who had subdural hematoma (SDH), 6 had worsening CT scans and 3 underwent burr hole drainage procedures as inpatients due to persistent SDH without new deficit. Of the 39 OP who had cerebral contusions, 3 had worsening CT scans and one required NSG admission. No patient returned to the ED with a complication. Follow-up was obtained on 81% of OP. 2 patients with SDH required burr hole procedure > 2 weeks after discharge.Conclusions
Patients with mTIH, particularly those with iSAH, have very low rates of clinical or radiographic deterioration and may be safe for monitoring in an emergency department observation unit. 相似文献15.

The depressed heart function is the main complication to cause death of septic patients in clinic. It is urgent to find effective interventions for this intractable disease. In this study, we investigated whether butyrate could be protective for heart against sepsis and the underlying mechanism.Methods
Mice were randomly divided into three groups. Model group challenged with LPS (30 mg/kg, i.p.) only. Butyrate group received butyrate (200 mg/kg·d) for 3 days prior to LPS administration (30 mg/kg). Normal group received saline only. 6 h and 12 h after LPS administration were chosen for detection the parameters to estimate the effects or mechanism of butyrate pretreatment on heart of sepsis.Results
The data showed that septic heart depression was attenuated by butyrate pretreatment through improvement of heart function depression (P < 0.01) and reduction of morphological changes of myocardium. The overexpression of proinflammatory factors, TNF-α, IL-6 and LTB4, in heart tissues induced by sepsis was significantly alleviated by butyrate pretreatment (P < 0.01). As oxidative stress indicators, SOD and CAT activity, and MDA content in heart were deteriorated by LPS challenge, which was noticeably ameliorated by butyrate pretreatment (P < 0.01 or P < 0.05).Conclusions
In conclusion, pretreatment with butyrate attenuated septic heart depression via anti-inflammation and anti-oxidation. 相似文献16.

Background
Systemic hemodynamic characteristics of patients with suspected acute ischemic stroke are poorly described. The objective of this study was to identify baseline hemodynamic characteristics of emergency department (ED) patients with suspected acute stroke.Methods
This was a planned analysis of the stroke cohort from a multicenter registry of hemodynamic profiling of ED patients. The registry prospectively collected non-invasive hemodynamic measurements of patients with suspicion for acute stroke within 12 h of symptom onset. K-means cluster analysis identified hemodynamic phenotypes of all suspected stroke patients, and we performed univariate hemodynamic comparisons based on final diagnoses.Results
There were 72 patients with suspected acute stroke, of whom 38 (53%) had a final diagnosis of ischemic stroke, 10 (14%) had hemorrhagic stroke, and 24 (33%) had transient ischemic attack (TIA). Analysis defined three phenotypic clusters based on low or normal cardiac index (CI) and normal or high systemic vascular resistance index (SVRI). Patients with TIA had lower mean CI (2.3 L/min/m2) compared to hemorrhagic or ischemic stroke patients (p < 0.01).Conclusions
The study demonstrates the feasibility of defining hemodynamic phenotypes of ED patients with suspected stroke. 相似文献17.
Background
Paraphimosis is an acute urologic emergency requiring urgent manual reduction, frequently necessitating procedural sedation (PS) in the pediatric population. The present study sought to compare outcomes among pediatric patients undergoing paraphimosis reduction using a novel topical anesthetic (TA) technique versus PS.Methods
We performed a retrospective analysis of all patients < 18 years old, presenting to a tertiary pediatric ED requiring analgesia for paraphimosis reduction between October 2013 and September 2016. The primary outcome was reduction first attempt success; secondary outcomes included Emergency Department length of stay (ED LOS), adverse events and return visits. Dichotomous outcomes were analyzed by Chi-square testing and multivariate linear regression was used to compare continuous variables.Results
Forty-six patients were included; 35 underwent reduction using TA, 11 by PS. Patient age and duration of paraphimosis at ED presentation did not differ between groups. There was no difference in first attempt success between TA (32/35, 91.4%) and PS groups (9/11, 81.8%; p = 0.37). Mean ED LOS was 209 min shorter for TA patients (148 min vs. 357 min, p = 0.001) and remained significantly shorter after controlling for age and duration of paraphimosis (adjusted mean difference ?198 min, p = 0.003). There were no return visits or major adverse events in either group, however, among successful reduction attempts, PS patients more frequently experienced minor adverse events (7/9 vs. 0/32, p < 0.001).Conclusions
Paraphimosis reduction using TA was safe and effective. Compared to PS, TA was associated with a reduced ED LOS and fewer adverse events. TA could potentially allow more timely reduction with improved patient experience and resource utilization. 相似文献18.

Background
Chemical restraint is often required to control agitation induced by methamphetamine. Dexmedetomidine is an α-2 adrenergic receptor agonist with sedative, analgesic, and sympatholytic properties. Its use in the emergency department (ED) to control methamphetamine-induced agitation has not been reported.Objective
To report two cases of methamphetamine-induced agitation successfully sedated with dexmedetomidine in the ED.Case Report
The first case was a 42-year-old man with unstable emotion and violent behaviours after smoking methamphetamine. His agitation did not respond to a large cumulative dose of benzodiazepines (10 mg of diazepam and 332 mg of midazolam) administered over 48 h and sedation was achieved with dexmedetomidine. The second case was a 38-year-old methamphetamine user with unstable emotion and recurrent episodes of agitation despite repeated doses of benzodiazepines, whose agitation was controlled with dexmedetomidine infusion.Discussion
In both cases, dexmedetomidine apparently reduced the dose of benzodiazepines needed to achieve adequate sedation. Transient falls in blood pressure and slowing of the heart rate were noted, which resolved either spontaneously or after reducing the infusion rate without requiring drug treatment.Conclusion
Dexmedetomidine can be considered as an adjunct for chemical restraint when standard treatment fails to control the agitation induced by methamphetamine, but patient's hemodynamic state should be monitored closely during administration. Its efficacy and safety in the ED warrant further evaluation with prospective controlled trials. 相似文献19.

Primary objective was to characterize lung ultrasound findings in children with asthma presenting with respiratory distress to the emergency department (ED). Secondary objectives included correlating these findings with patients' clinical course in the ED.Methods
Eligible patients 2–17 years of age, underwent a lung ultrasound by the study sonographer between November 2014 to December 2015. Positive lung ultrasound was defined as the presence of ≥ 1 of the following findings: ≥ 3 B-lines per intercostal space, consolidation and/or pleural abnormalities. The treating physician remained blinded to ultrasound findings; clinical course was extracted from the medical chart.Results
A total of sixty patients were enrolled in this study. Lung ultrasound was positive in 45% (27/60) of patients: B-line pattern in 38%, consolidation in 30% and pleural line abnormalities in 12%. A positive lung ultrasound correlated with increased utilization of antibiotics (26% vs 0%, p = 0.03), prolonged ED length of stay (30% vs. 9%, p = 0.04) and admission rate (30% vs 0%, p = 0.03). Inter-rater agreement between novice and expert sonographers was excellent with a kappa of 0.92 (95% CI: 0.84–1.00).Conclusions
This study characterized lung ultrasound findings in pediatric patients presenting with acute asthma exacerbations; nearly half of whom had a positive lung ultrasound. Positive lung ultrasounds were associated with increased ED and hospital resource utilization. Future prospective studies are needed to determine the utility and reliability of this tool in clinical practice. 相似文献20.
