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.

Introduction
Blunt trauma is a leading cause of pediatric morbidity. We compared injuries, interventions and outcomes of acute pediatric blunt torso trauma based on intent.Methods
We analyzed de-identified data from a prospective, multi-center emergency department (ED)-based observational cohort of children under age eighteen. Injuries were classified based on intent (unintentional/inflicted). We compared demographic, physical and laboratory findings, ED disposition, hospitalization, need for surgery, 30-day mortality, and cause of death between groups using Chi-squared or Fisher's test for categorical variables, and Mann-Whitney test for non-normal continuous factors comparing median values and interquartile ranges (IQR).Results
There were 12,044 children who sustained blunt torso trauma: Inflicted = 720 (6%); Unintentional = 9563 (79.4%); Indeterminate = 148 (1.2%); Missing = 1613 (13.4%). Patients with unintentional torso injuries significantly differed from those with inflicted injuries in median age in years (IQR) [10 (5, 15) vs. 14 (8, 16); p-value < 0.001], race, presence of pelvic fractures, hospitalization and need for non-abdominal surgery. Mortality rates did not differ based on intent. Further adjustment using binary, logistic regression revealed that the risk of pelvic fractures in the inflicted group was 96% less than the unintentional group (OR: 0.04; 95%CI: 0.01–0.26; p-value = 0.001).Conclusions
Children who sustain acute blunt torso trauma due to unintentional causes have a significantly higher risk of pelvic fractures and are more likely to be hospitalized compared to those with inflicted injuries. 相似文献5.
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6.

Background and purpose
Accurate diagnosis of acute aortic dissection (AAD) is sometimes difficult because of accompanying central nervous system (CNS) symptoms. The purpose of this study was to investigate the clinical characteristics of Type A AAD (TAAAD) with CNS symptoms.Methods
We retrospectively reviewed the medical records of 8403 patients ambulanced to our emergency and critical care center between April 2009 and May 2014.Results
We identified 59 TAAAD patients for the analysis (mean age, 67.3 ± 10.5 years; 37 (62.0%) male). Eleven patients (18.6%) presented CNS symptoms at the onset of TAAAD, and these patients complained less frequently of typical chest and back pain than those without CNS symptoms (p < 0.0001). Initial systolic and diastolic blood pressure were lower (p = 0.003, and p = 0.049, respectively) and involvement of the supra-aortic artery was more frequent in patients with CNS symptoms (p < 0.0001).Conclusion
Because CNS symptom can mask chest and back pain caused by TAAAD, physicians should always consider the possibility of TAAAD in patients with CNS symptoms in emergency medicine settings. 相似文献7.

Study objectives
Facing increased utilization and subsequent capacity and budget constraints, ED's must better understand bottlenecks and their effect on process flow to improve process efficiency. The primary objective of this study was to identify bottlenecks in obtaining a head CT and investigate patient waiting time based on those bottlenecks.Methods
This observational study included all patients undergoing a head CT between July 1, 2013 and June 30, 2014 at a large, urban academic ED with over 100,000 visits per year.The primary study outcome was total cycle time, defined as the elapsed time between patient arrival and head CT preliminary report, divided into four components of workflow.Results
8312 patients who had a head CT were included in this study. The median cycle time from patient arrival to head CT preliminary report was 3 h and 13 min with 39 min of waiting time resulting from bottlenecks. In the 4-step model (time from patient arrival to head CT order, time from head CT order to head CT scheduled, time from head CT scheduled to head CT completed, and time from head CT completed to head CT preliminary report), each process was the bottleneck 30%, < 1%, 27%, and 42% of the time, respectively.Conclusion
Demand capacity mismatch in head CT scanning has a significant impact on patient waiting times. This study suggests opportunities to improve wait times through future research to understand the causes of delays in CT ordering, CT completion and timeliness of radiology reports. 相似文献8.

Objectives
The effect of the Affordable Care Act on emergency department (ED) high utilizers has not yet been thoroughly studied. We sought to determine the impact of changes in insurance eligibility following the 2014 Medicaid expansion on ED utilization for ambulatory care sensitive conditions (ACSC) by high ED utilizers in an urban safety net hospital.Methods
High utilizers were defined as patients with ≥ 4 visits in the 6 months before their most recent visit in the study period (July–December before and after Maryland's Medicaid expansion in January 2014). A differences-in-differences approach using logistic regression was used to investigate if differences between high and low utilizer cohorts changed from before and after the expansion.Results
During the study period, 726 (4.1%) out of 17,795 unique patients in 2013 and 380 (2.4%) of 16,458 during the same period in 2014 were high utilizers (p-value < 0.001). ACSC-associated visit predicted being a high utilizer in 2013 (OR 1.66 (95% CI [1.37, 2.01])) and 2014 (OR 1.65 (95% CI [1.27, 2.15])) but this was not different between years (OR ratio 0.99, 95% CI [0.72, 1.38], p-value 0.97).Conclusion
Although the proportion of high utilizers decreased significantly after Maryland's Medicaid expansion, ACSC-associated ED visits by high ED utilizers were unaffected. 相似文献9.

Objective
Local forms of the tranexamic acid have been effective in treating many haemorrhagic cases. So that the aim of the current study is to assess the effectiveness of local tranexamic acid in controlling painless hematuria in patients referred to the emergency department.Methods
This is a randomized, double-blind clinical trial study, which was conducted on 50 patients with complaints of painless lower urinary tract bleeding during June 2014 and August 2015. The patients were randomly divided into two groups of 25 people each, one group receiving tranexamic acid and the other given a placebo. During bladder irrigation, local tranexamic acid and the placebo were injected into the bladder via Foley catheter. Patients were examined over 24 h in terms of the amount of normal saline serum used for irrigation, level of hemoglobin, and blood in urine.Results
In this study it was observed that consumption of tranexamic acid significantly decreased the volume of used serum for bladder irrigation (P = 0.041) and the microscopic status of urine decreased significantly in terms of the hematuria after 24 h (P = 0.026). However, the rate of packed cell transfusion and drop in hemoglobin levels showed no significant difference in both groups of patients (P ? 0.05).Conclusion
The results of this study showed that tranexamic acid could significantly reduce the volume of required serum for bladder irrigation to clear urine, but it had no significant effect on the drop in serum hemoglobin levels. 相似文献10.

Objective
This research is to study if quick administration of adrenaline on OHCA prior to hospitalization has an effect on improving CPC1-2 at one month.Methodology
A total 13,326 cases were extracted from 2011 to 2014 Utstein data for this retrospective cohort study, also, EMT reached the patients within 16 min after 119 called and adrenaline was then administered within 22 min of after contact.Patients divided into two groups
Patients were contacted within 8 min of the 119 call (n = 6956), and were contacted between 8 and 16 min after the call (n = 6370). Further divided into groups in which the adrenaline was administered within/without 10 min after contact. Primary outcome was the rate of a good prognosis for cerebral performance (CPC1-2) at 1 month and secondary outcome was the return of spontaneous circulation (ROSC) rate.Results
The odds ratio of the CPC1-2 at 1 month by the EMS reached within 8 min after 119 call and then adrenaline administered within 10 min was 2.12 (1.54–2.92).Those reached between 8 and 16 min was 2.66 (1.97–3.59). However, the ROSC rate was 2.00 (1.79–2.25) for those reached within 8 min and also 2.00 (1.79–2.25) for those reached between 8 min and 16 min.Considerations
In cases of OHCA, it appears that the CPC1-2 rate after 1 month can be improved even in cases where the victim is reached > 8 min after the 119 call, as long as the victim is reached within 16 min and emergency responders administer the adrenaline as quickly as possible. 相似文献11.

Background
Respiratory syncytial virus (RSV) and influenza have varying degree of seasonal overlap.Objective
To determine the prevalence of co-infection of RSV and influenza compared to the prevalence of those infections independently when both are in season.Methods
This was a retrospective cross-sectional study of children evaluated between July 2010 and June 2013 for viral respiratory infection using multiplex PCR. Seasonality was defined retrospectively as weeks when > 2% of the total annual positive tests were obtained and was calculated for influenza A, influenza B, and RSV independently. Periods of overlapping seasonality of RSV and influenza A and RSV and influenza B were identified. The expected incidences of co-infection were modeled as the product of the incidences of the individual viruses.Results
13,664 specimens were sent for PCR during the study period. Over all 3 seasons, RSV overlapped with influenza A and B for 22 and 18 weeks, respectively; in 2011–12, RSV overlapped with neither influenza A nor B. Based on modeling, there were 6–7 fold fewer cases of RSV/influenza co-infection observed than expected: RSV/influenza A 77 vs. 12, (p ≤ 0.001; RSV/influenza B 76 vs. 11 (p ≤ 0.001).Conclusions
The observed incidence of co-infectivity of RSV and influenza was significantly less than the expected incidence even when both were co-circulating. In light of these data, it may be reasonable to forgo rapid influenza testing or empiric antiviral treatment for children whom rapid RSV testing is positive and who are at low risk of influenza-related complications, especially in times of antiviral therapy shortages. 相似文献12.

Objectives
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13.

Aim
Bacteremia is an uncommon complication of urinary tract infection (UTI). The aim of this study was to identify risk factors for bacteremic UTI in pediatric patients.Methods
The medical records of all pediatric patients with UTI between 2013 and 2014 were retrospectively reviewed. Pediatric patients with accompanying bacteremia were compared with pediatric patients with no bacteremia.Results
Five hundred twenty-seven cases of UTI were identified. Blood cultures were taken in 464, 26 (5.6%) of which also were bacteremic. Pediatric patients with bacteremia were more likely to be male (58% vs 28%, P < .01), to be younger than 3 months (54% vs 31%, P = .02), and to have higher creatinine (average 0.77 ± 0.97 vs 0.34 ± 0.24, P < .01). Pediatric patients with bacteremia had higher rate of underlying urologic conditions. The following variables were included in multivariate analysis: age < 3 months, sex, ethnicity, method of urine collection, creatinine, and underlying urologic conditions. Only creatinine (odds ratio, 3.67; 95% confidence interval, 1.69-8.11) was found as an independent risk factor for bacteremia.Conclusions
High creatinine at presentation is a risk factor that might aid in early identification of pediatric patients with high risk for bacteremia and its complications. 相似文献14.

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15.

Objectives
Constipation is a common cause of abdominal pain in children presenting to the emergency department (ED). The objectives of this study were to determine the diagnostic evaluation undertaken for constipation and to assess the association of the evaluation with final ED disposition.Methods
A retrospective chart review of children presenting to the pediatric ED of a quaternary care children's hospital with abdominal pain that received a soap suds enema therapy.Results
A total of 512 children were included, 270 (52.7%) were female, and the median age was 8.0 (IQR: 4.0–11.0). One hundred and thirty eight patients (27%) had a digital rectal exam (DRE), 120 (22.8%) had bloodwork performed, 218 (43%) had urinalysis obtained, 397 (77.5%) had abdominal radiographs, 120 (23.4%) had abdominal ultrasounds, and 18 (3.5%) had computed tomography scans. Children who had a DRE had a younger median age (6.0, IQR: 3.0–9.25 vs. 8.0, IQR: 4.0–12.0; p < 0.001) and were significantly less likely to have radiologic imaging (OR = 0.50, 95% CI 0.32–0.78; p = 0.002), but did not have an increased odds of being discharged home. After adjusting for gender, ethnicity, and significant past medical history those with an abdominal radiograph were less likely to be discharged to home (aOR = 0.56, 95% CI 0.31–1.01; p = 0.05).Conclusions
The diagnostic evaluation of children diagnosed with fecal impaction in the ED varied. Abdominal imaging may be avoided if children receive a DRE. When children presenting to the ED with abdominal pain had an abdominal radiograph, they were more likely to be admitted. 相似文献16.

Purpose
The objective of this study was to assess the efficacy of paracetamol (acetaminophen) on body temperature in acute stroke.Methods
Medline, Cochrane Central Register of Controlled Trials, EMBASE, Chinese BioMedical Literature Database, China National Knowledge Infrastructure, and the World Health Organization (WHO) International Clinical Trials Registry Platform were searched electronically. Relevant journals and references of studies included were hand-searched for randomized controlled trials (RCT) and controlled clinical trials (CCT) regarding the efficacy of paracetamol (acetaminophen) on body temperature in acute stroke. Two reviewers independently performed data extraction and quality assessment. Data were analyzed using RevMan 5.3 software by the Cochrane Collaboration.Results
Five studies were included. To compare the efficacy of paracetamol (acetaminophen) in acute stroke, the pooled RR (Risk Ratio) and its 95% CI of body temperature reduction at 24 h from the start of treatment were ? 0.3 (95% CI: ? 0.52 to ? 0.08), with statistical significance (P = 0.007). Consistently, the pooled RR (Risk Ratio) and its 95% CI of body temperature at 24 h from the start of treatment were ? 0.22 (? 0.29, ? 0.15), with statistical significance (P < 0.00001). When analyzing the body temperature reduction after 5 days from the start of treatment, the pooled RR (Risk Ratio) and its 95% CI were 0.04 (95% CI: ? 0.20 to 0.29), with no statistical significance (P = 0.73). For functional outcome (mRS ≤ 2) analysis, the pooled RR and its 95% CI were 1.08 (0.88, 1.32), with no statistical significance (P = 0.45). In addition, the difference of serious adverse events between acetaminophen and placebo was 0.86 (95% CI: 0.62 to 1.2), with no statistical significance (P = 0.27).Conclusion
Acetaminophen was revealed to have some favorable influence in body temperature reduction in acute stroke, but showed no important effect on improving functional outcome and reducing adverse events of patients.What this paper adds
What is already known on this subject?Paracetamol (acetaminophen) is one of the most commonly used antipyretic drugs and has some capability to reduce body temperature through acting on central nervous system.What this study adds
Acetaminophen showed some capability to decrease body temperature for acute stroke.Acetaminophen could not improve functional outcome and reduce adverse events of patients with acute stroke. 相似文献17.

Purpose
The objectives of this study were to evaluate emergency medicine resident-performed ultrasound for diagnosis of effusions, compare the success of a landmark-guided (LM) approach with an ultrasound-guided (US) technique for hip, ankle and wrist arthrocentesis, and compare change in provider confidence with LM and US arthrocentesis.Methods
After a brief video on LM and US arthrocentesis, residents were asked to identify artificially created effusions in the hip, ankle and wrist in a cadaver model and to perform US and LM arthrocentesis of the effusions. Outcomes included success of joint aspiration, time to aspiration, and number of attempts. Residents were surveyed regarding their confidence in identifying effusions with ultrasound and performing LM and US arthrocentesis.Results
Eighteen residents completed the study. Sensitivity of ultrasound for detecting joint effusion was 86% and specificity was 90%. Residents were successful with ultrasound in 96% of attempts and with landmark 89% of attempts (p = 0.257). Median number of attempts was 1 with ultrasound and 2 with landmarks (p = 0.12). Median time to success with ultrasound was 38 s and 51 s with landmarks (p = 0.23). After the session, confidence in both US and LM arthrocentesis improved significantly, however the post intervention confidence in US arthrocentesis was higher than LM (4.3 vs. 3.8, p < 0.001).Conclusions
EM residents were able to successfully identify joint effusions with ultrasound, however we were unable to detect significant differences in actual procedural success between the two modalities. Further studies are needed to define the role of ultrasound for arthrocentesis in the emergency department. 相似文献18.

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19.

Objective
This study investigates unintentional non-fatal golf-related injuries in the US using a nationally representative database.Methods
This study analyzed golf-related injuries treated in US hospital emergency departments from 1990 through 2011 using the National Electronic Injury Surveillance System database. Injury rates were calculated using golf participation data.Results
During 1990 through 2011, an estimated 663,471 (95% CI: 496,370–830,573) individuals ≥ 7 years old were treated in US emergency departments for golf-related injuries, averaging 30,158 annually or 12.3 individuals per 10,000 golf participants. Patients 18–54 years old accounted for 42.2% of injuries, but injury rates per 10,000 golf participants were highest among individuals 7–17 years old (22.1) and ≥ 55 years old (21.8) compared with 18–54 years old (7.6). Patients ≥ 55 years old had a hospital admission rate that was 5.01 (95% CI: 4.12–6.09) times higher than that of younger patients. Injured by a golf club (23.4%) or struck by a golf ball (16.0%) were the most common specified mechanisms of injury. The head/neck was the most frequently injured body region (36.2%), and sprain/strain (30.6%) was the most common type of injury. Most patients were treated and released (93.7%) and 5.9% required hospitalization.Conclusions
Although golf is a source of injury among all age groups, the frequency and rate of injury were higher at the two ends of the age spectrum. Given the higher injury and hospital admission rates of patients ≥ 55 years, this age group merits the special attention of additional research and injury prevention efforts. 相似文献20.
