Aim
To investigate characteristics and outcome among patients suffering in-hospital cardiac arrest (IHCA) with the emphasis on gender and age.Methods
Using the Swedish Register of Cardiopulmonary Resuscitation, we analyzed associations between gender, age and co-morbidities, etiology, management, 30-day survival and cerebral function among survivors in 14,933 cases of IHCA. Age was divided into three ordered categories: young (18–49 years), middle-aged (50–64 years) and older (65 years and above). Comparisons between men and women were age adjusted.Results
The mean age was 72.7 years and women were significantly older than men. Renal dysfunction was the most prevalent co-morbidity. Myocardial infarction/ischemia was the most common condition preceding IHCA, with men having 27% higher odds of having MI as the underlying etiology. A shockable rhythm was found in 31.8% of patients, with men having 52% higher odds of being found in VT/VF. After adjusting for various confounders, it was found that men had a 10% lower chance than women of surviving to 30 days. Older individuals were managed less aggressively than younger patients. Increasing age was associated with lower 30-day survival but not with poorer cerebral function among survivors.Conclusion
When adjusting for various confounders, it was found that men had a 10% lower chance than women of surviving to 30 days after in-hospital cardiac arrest. Older individuals were managed less aggressively than younger patients, despite a lower chance of survival. Higher age was, however, not associated with poorer cerebral function among survivors. 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
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5.

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.

Objective
Pulmonary embolism is a relatively common clinical presentation of venous thromboembolism, which develops in relation to acute pulmonary arterial occlusion mostly caused by thrombi of the lower limbs.Case report
29 year old female admitted to emergency department with pulmonary thromboembolism due to an ingestion of 17 Diana 35 pills (2 mg cyproterone acetate and 0.035 mg ethinyl estradiol) in a suicide attempt without any previously known predisposing factors. After thrombolytic therapy, the patient was discharged with oral warfarin treatment.Discussion
We know that exogenous estrogen increase the risk of venous thromboembolism in therapeutic use. It should be kept in mind that even single ingestion of a single high-dose exogenous estrogen intake may induce pulmonary thromboembolism. 相似文献8.

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9.

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10.

Purpose
To investigate the difference in pentraxin 3 (PTX 3) levels between patients with pulmonary contusion and healthy volunteers.Materials and methods
This study was conducted with a group of 20 trauma patients diagnosed with pulmonary contusion and 30 healthy individuals enrolled as a control group in a tertiary university hospital.Results
Median PTX 3 levels were 7.05 (3.29–13.1), ng/ml in the contusion group and 1.03 (0.7–1.58) ng/ml in the control group. PTX 3 titers were significantly higher in patients with pulmonary contusion compared to those of the control group (p < 0.001). An area under the curve (AUC) value of 0.968 investigated using ROC analysis to determine the diagnostic value of the PTX-3 in pulmonary contusion patients was measured. A PTX-3 cut-off value of 2.06 produced 95.5% sensitivity and 86.7% specificity.Conclusion
PTX 3 levels in pulmonary contusion increased significantly compared to the healthy control group. If supported by wider series, PTX 3 may be expected to be capable of use as a marker in pulmonary contusion. 相似文献11.

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12.

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13.

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14.

Objective
A wide variety of spinal needles are used in clinical practice. Little is currently known regarding the impact of needle length, gauge, and tip type on the needle's ability to measure spinal canal opening pressure. This study aimed to investigate the relationship between these factors and the opening-pressure measurement or time to obtain an opening pressure.Methods
Thirteen distinct spinal needles, chosen to isolate the effects of length, gauge, and needle-point type, were prospectively tested on a lumbar puncture simulator. The key outcomes were the opening-pressure measurement and the time required to obtain that measure. Pressures were recorded at 10-s intervals until 3 consecutive, identical readings were observed.Results
Time to measure opening pressure increased with increasing spinal needle length, increasing gauge, and the Quincke-type (cutting) point (P < 0.001 for all). The time to measurement ranged from 30 s to 530 s, yet all needle types were able to obtain a consistent opening pressure measure.Conclusion
Although opening pressure estimates are unlikely to vary markedly by needle type, the time required to obtain the measurement increased with increasing needle length and gauge and with Quincke-type needles. 相似文献15.

Objectives
To validate the effects of the new plateau hyperbaric chamber on alleviating high altitude hypoxia on Mount Kun Lun.Methods
A prospective, controlled study of rabbits and adult volunteers was conducted at altitudes of 355, 2880 and 4532 m. We obtained arterial blood samples from rabbits and volunteers before and after hyperbaric treatment. The respiratory rate, heart rate, and blood pressure (BP) of adult volunteers were monitored during hyperbaric treatment.Results
The mean PaO2 levels of experimental group rabbits and volunteers increased significantly after 60 min of hyperbaric treatment at 350, 2880 and 4532 m. The mean PaCO2 and pH levels of rabbits were not significant different before and after hyperbaric treatment at each altitude. The mean PaCO2 and pH levels were not significant different at 355 m in the human study. However, at 2880 and 4532 m, pH fell with increasing PaCO2 levels in humans before and after hyperbaric treatment.Conclusions
The new multiplace plateau hyperbaric chamber may be used to alleviate plateau hypoxia by increasing patient PaO2. However, its value in treating AMS must be confirmed in field conditions. 相似文献16.

Study objective
We investigated the serum sodium correction rate on length of hospitalization and survival rate, in severe chronic hyponatremic patients at the Emergency Department (ED).Design
An observational study using clinical chart review.Setting
The ED of the University Hospital of Marcianise, Caserta, Italy with approximately 30,000 patients visits a year.Type of participants
We reviewed sixty-seven patients with severe hyponatremia subdivided in 2 subgroups: group A consisting of 35 patients with serum sodium correction rate < 0.3 mmol/h and group B consisting of 32 patients with serum sodium correction rate between < 0.5 and ≥ 0.3 mmol/h.Intervention
Emergency patients were evaluated for serum sodium correction rate for hyponatremia by clinical chart review.Measurements and main results
Severe hyponatremia was defined as a serum sodium level < 120 mmol/l. Mean serum sodium correction rate of hyponatremia was of 0.17 ± 0.09% in group A and 0.41 ± 0.05% in group B (p < 0.001 vs group A). The length of hospital stay was 10.7 ± 3.7 days for group A, and it was significantly decreased to 3.8 ± 0.4 days for group B (p < 0.005 vs group A). In addition we observed that correction rate of hyponatremia in group A was associated with a significantly lower survival rate (25%) in comparison to group B (60%) (p < 0.001 vs group A).Conclusion: We observed that serum sodium correction rate ≥ 0.3 and < 0.5 mmol/h was associated with a shorter length of hospital stay and a major survival rate. 相似文献17.

Background
Though hospitals' operational continuity is crucial, full institutional evacuation may at times be unavoidable. The study's objective was to establish criteria for discharge of patients during complete emergency evacuation and compare scope of patients suitable for discharge pre/post implementation of criteria.Basic procedures
Standards for patient discharge during an evacuation were developed based on literature and disaster managers. The standards were reviewed in a two-round Delphi process. All hospitals in Israel were requested to identify inpatients' that could be released home during institutional evacuation. Potential discharges were compared in 2013–2014, before and after formulation of discharge criteria.Main findings
Consensus exceeding 80% was obtained for four out of five criteria after two Delphi cycles. Average projected discharge rate before and after formulation of criteria was 34.2% and 42.9%, respectively (p < 0.001). Variance in potential dischargeable patients was 31-fold less in 2014 than in 2013 (MST = 8,452 versus MST = 264,366, respectively; p < 0.001). Differences were found between small, medium and large hospitals in mean rate of dischargeable patients: 52.1%, 41.5% and 42.2%, respectively (p = 0.001).Principle conclusions
The study's findings enable to forecast the extent of patients that may be released home during full emergency evacuation of a hospital; thereby facilitating preparedness of contingency plans. 相似文献18.

Background
Acute dyspnea affects a large heterogeneous patient group with high mortality and readmission rates.Purpose
To investigate if cardiometabolic biomarkers and clinical characteristics predict readmission and death in patients hospitalized for acute dyspnea.Methods
65 dyspnea patients at a general internal medicine ward were followed for six months. The combined endpoint was readmission or death.Measurements and results
Cardiometabolic biomarkers at admission were related to the endpoint in Cox proportional hazard models (adjusted for sex, age, oxygen saturation, respiratory rate and C-reactive protein (CRP)). The biomarkers tissue-type plasminogen activator (tPA), prolactin (PRL), tumor necrosis factor receptor superfamily member 6 (FAS) and C-C motif chemokine 3 (CCL3) were independently and significantly related to the endpoint and combined into a biomarker risk score (BRS). Each SD increment of the BRS conferred a hazard ratio (HR) of 2.13 (1.39–3.27) P = 0.001. The top vs bottom tertile of the BRS conferred a HR of 4.75 (1.93–11.68) P = 0.001. Dyspnea severity was also associated with worse outcome, HR = 3.43 (1.28–9.20) P = 0.014. However, when mutually adjusted the BRS remained significant (P = 0.004) whereas dyspnea severity was not. The BRS was related to the endpoint among patients with mild to moderate dyspnea (P = 0.016) but not among those with severe dyspnea.Conclusion
A score of tPA, PRL, FAS and CCL3 predicts 6-month death and readmission in patients hospitalized for acute dyspnea and may prove useful to optimize length of stay and follow-up. Although the BRS outweighs dyspnea severity in prediction of the endpoint, its prognostic role is strongest in mild-moderate dyspnea. 相似文献19.

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20.
