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2.

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3.

Purpose
The aim of this study is to compare the effectiveness of active recovery in form of running or foam rolling on clearing blood lactate compared to remain sitting after a water rescue.Method
A quasi experimental cross-over design was used to test the effectiveness of two active recovery methods: foam rolling (FR) and running (RR), compared with passive recovery (PR) on the blood lactate clearance after performing a water rescue. Twelve lifeguards from Marín (Pontevedra) completed the study. The participants performed a 100-meter water rescue and a 25-minute recovery protocol.Results
The post recovery lactate levels were significantly lower for foam rolling (4.4 ± 1.5 mmol/l, P = 0.005, d = 0.94) and running (4.9 ± 2.3 mmol/l, P = 0.027, d = 1.21) compared with resting (7.2 ± 2.5 mmol/l); there was no significant difference between foam rolling and running (P = 1.000).Conclusions
We found that surf lifesavers clear out blood lactate more efficient when performing an active recovery protocol. Foam rolling is an effective method of increasing the rate of blood lactate clearance. These two recovery methods are also adequate for surf lifeguards as they do not interfere with the surveillance aspect of their job. 相似文献4.

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5.

Objectives
The purpose of this study was to compare health care resource utilization among patients who were given intravenous nitroglycerin for acute heart failure (AHF) in the emergency department (ED) by intermittent bolus, continuous infusion, or a combination of both.Methods
We retrospectively identified 395 patients that received nitroglycerin therapy in the ED for the treatment of AHF over a 5-year period. Patients that received intermittent bolus (n = 124) were compared with continuous infusion therapy (n = 182) and combination therapy of bolus and infusion (n = 89). The primary outcomes were the frequency of intensive care unit (ICU) admission and hospital length of stay (LOS).Results
On unadjusted analysis, rates of ICU admission were significantly lower in the bolus vs infusion and combination groups (48.4% vs 68.7% vs 83%, respectively; P < .0001) and median LOS (interquartile range) was shorter (3.7 [2.5-6.2 days]) compared with infusion (4.7 [2.9-7.1 days]) and combination (5.0 [2.9-6.7 days]) groups; P = .02. On adjusted regression models, the strong association between bolus nitroglycerin and reduced ICU admission rate remained, and hospital LOS was 1.9 days shorter compared with infusion therapy alone. Use of intubation (bolus [8.9%] vs infusion [8.8%] vs combination [16.9%]; P = .096) and bilevel positive airway pressure (bolus [26.6%] vs infusion [20.3%] vs combination [29.2%]; P = .21) were similar as was the incidence of hypotension, myocardial injury, and worsening renal function.Conclusions
In ED patients with AHF, intravenous nitroglycerin by intermittent bolus was associated with a lower ICU admission rate and a shorter hospital LOS compared with continuous infusion. 相似文献6.

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7.

Background
The aim of this study was to investigate whether the 1-year survival rate of out-of-hospital cardiac arrest (OHCA) patients with malignancy was different from that of those without malignancy.Methods
All adult OHCA patients were retrospectively analyzed in a single institution for 6 years. The primary outcome was 1-year survival, and secondary outcomes were sustained return of spontaneous circulation (ROSC), survival to hospital admission, survival to discharge and discharge with a good neurological outcome (CPC 1 or 2). Kaplan-Meier survival analysis and Cox proportional hazard regression analysis were performed to test the effect of malignancy.Results
Among 341 OHCA patients, 59 patients had malignancy (17.3%). Sustained ROSC, survival to admission, survival to discharge and discharge with a good CPC were not different between the two groups. The 1-year survival rate was lower in patients with malignancy (1.7% vs 11.4%; P = 0.026). Kaplan-Meier survival analysis revealed that patients with malignancy had a significantly lower 1-year survival rate when including all patients (n = 341; P = 0.028), patients with survival to admission (n = 172, P = 0.002), patients with discharge CPC 1 or 2 (n = 18, P = 0.010) and patients with discharge CPC 3 or 4 (n = 57, P = 0.008). Malignancy was an independent risk factor for 1-year mortality in the Cox proportional hazard regression analysis performed in patients with survival to admission and survival to discharge.Conclusions
Although survival to admission, survival to discharge and discharge with a good CPC rate were not different, the 1-year survival rate was significantly lower in OHCA patients with malignancy than in those without malignancy. 相似文献8.

Background
Sex differences in heart diseases, including acute coronary syndrome, congestive heart failure, and atrial fibrillation, have been studied extensively. However, data are lacking regarding sex differences in pericarditis and myopericarditis patients.Objectives
The purpose of the study was to evaluate whether there are sex differences in pericarditis and myopericarditis patients as well.Methods
We performed a retrospective, single-center observational study that included 200 consecutive patients hospitalized with idiopathic pericarditis or myopericarditis from January 2012 to April 2014. Patients were evaluated for sex differences in prevalence, clinical presentation, laboratory variables, and outcome. We excluded patients with a known cause for pericarditis.Results
Among 200 consecutive patients, 55 (27%) were female. Compared with men, women were significantly older (60 ± 19 years vs 46 ± 19 years, P < .001) and had a higher rate of chronic medical conditions. Myopericarditis was significantly more common among men (51% vs 25%, P = .001). Accordingly, men had significantly higher levels of peak troponin (6.8 ± 17 ng/mL vs 0.9 ± 2.6 ng/mL, P < .001), whereas women presented more frequently with pericardial effusion (68% vs 45%, P = .006). Interestingly, women had a significantly lower rate of hospitalization in the cardiology department (42% vs 63%, P = .015). Overall, there were no significant differences in ejection fraction, type of treatment, complications, or in-hospital mortality.Conclusions
Most patients admitted with acute idiopathic pericarditis are male. In addition, men have a higher prevalence of myocardial involvement. Significant sex differences exist in laboratory variables and in hospital management; however, the outcome is similar and favorable in both sexes. 相似文献9.
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10.

Objectives
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11.

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12.

Purpose
Obesity is a well-known risk factor in various health conditions. We analyzed the association between obesity and clinical outcomes, and its effect on targeted temperature management (TTM) practice for cardiac arrest survivors by calculating and classifying their body mass indexes (BMIs).Methods
We conducted a retrospective data analysis of adult comatose cardiac arrest survivors treated with TTM from 2008 to 2015. BMI was calculated and the cohort was divided into four categories based on the cut-off values of 18.5, 23.0, and 27.5 kg m? 2. The primary outcome was six-month mortality and the secondary outcomes were neurologic outcome at hospital discharge, cooling rate, and rewarming rate.Results
The study included 468 patients. Poor neurologic outcome at discharge and six-month mortality were reported in 311 (66.5%) and 271 (57.9%) patients, respectively. A multivariate logistic analysis showed that an overweight compared to normal BMI was associated with lower probability of six-month mortality (odds ratio [OR], 0.481; 95% confidence interval [CI], 0.274–0.846; p = 0.011) and poor neurologic outcome at discharge (OR, 0.482; 95% CI, 0.258–0.903; p = 0.023). BMI correlated with cooling rate (B, ? 0.073; 95% CI, ? 0.108 to ? 0.039; p < 0.001), but had no association with rewarming rate (B, 0.003; 95% CI, ? 0.001–0.008; p = 0.058).Conclusion
Overweight BMI compared to normal BMI classification was found to be associated with lower six-month mortality and poor neurologic outcome at discharge in cardiac arrest survivors treated with TTM. Higher BMI correlated with a slower induction rate. 相似文献13.

Background
The HEART score has been validated as a predictor of major adverse cardiac events (MACEs) in emergency department patients complaining of chest pain. Our objective was to determine the extent of physician variation in the HEART score of admitted patients stratified by years of experience.Methods
We performed a retrospective medical record review at an academic tertiary care emergency department to determine HEART score, outcome of hospitalization, and 30-day MACE. Electrocardiograms were graded by consensus between 3 physicians. We used analysis of variance to determine the difference in mean HEART scores between providers, Fisher's exact test to determine difference in MACE by duration of training, and logistic regression to determine predictors of low-risk admission (HEART score ≤ 3).Results
The average mean HEART score for 19 full-time physicians was 4.41 (SD 0.43). Individually, there was no difference in mean scores (P = .070), but physicians with 10-15 years of experience had significantly higher mean scores than those with 0-5 years of experience (mean HEART score 4.65 vs 3.93, P = .012). Those with 10-15 years of experience also had a significantly higher proportion of MACE in their admitted cohort (15.3%, P = .002).Conclusions
More experienced providers admitted higher-risk patients and were more likely to admit patients who would experience a MACE. More research is needed to determine whether adding the HEART score for clinical decision making can be used prospectively to increase sensitivity for admitting patients at high risk for MACE and to decrease admissions for chest pain in lower-risk patients by less experienced providers. 相似文献14.

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15.

Objectives
Several reports have compared the efficacy of linezolid (LZD) in Methicillin-resistant Staphylococcus aureus (MRSA) infections with that of vancomycin (VCM); however, these two antibiotics for the treatment of nosocomial MRSA pneumonia in elderly patients has not been well evaluated. The purpose of this study is to evaluate the efficacy and safety of LZD compared with VCM for the treatment of elderly patients with nosocomial MRSA pneumonia in a retrospective chart review of a cohort.Methods
We included 28 consecutive patients aged ≥ 65 years hospitalized with a confirmed diagnosis of MRSA pneumonia and treated with LZD (n = 11) or VCM (n = 17) between November 2010 and May 2015. We collected patient, disease, and laboratory data. The primary outcome was 30-day mortality. The secondary outcomes were the sequential organ failure assessment (SOFA) total, respiratory, renal, coagulation, hepatic, cardiovascular, and central nervous system scores on days 1, 3, 7, and 14.Results
There were no significant differences between the two groups with regard to baseline characteristics. The 30-day mortality rate was significantly lower in the LZD group than in the VCM group (0% vs. 41%, P = .02). The SOFA total score on days 3, 7, and 14 were significantly lower those at baseline in the LZD group (P < .05). The SOFA respiratory score on days 14 was also significantly lower than baseline in the LZD group (P < .05).Conclusion
LZD may be more efficacious than VCM for treating elderly patients with nosocomial MRSA pneumonia. 相似文献16.

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17.

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18.

Purpose
To assess the efficacy of Shenfu injection (SFI) for enhancing cellular immunity and improving the clinical outcomes of patients with septic shock.Methods
Patients with sepsis were randomly assigned to receive either SFI at a dose of 100 mL every 24 hours for 7 consecutive days or a placebo in addition to conventional therapy. The immunologic parameters were collected on days 1, 3, and 7 after the above treatments, and the clinical outcomes were updated for 28 days.Results
Of these160 patients, 3 were excluded from the analysis due to protocol violation and withdrawal of consent; thus, 157 completed the study (78 in the SFI group and 79 in the placebo group). We found that SFI increased both CD4+ and CD8+ T cells in peripheral blood and up-regulated HLA-DR expression in monocytes (P < .05). Furthermore, SFI was also found to restore ex vivo monocytic tumor necrosis factor α and interleukin 6 proinflammatory cytokine release in response to the endotoxin (P < .05). Importantly, the SFI group showed better clinical outcomes than did the placebo group in terms of the duration of vasopressor use (P = .008), Acute Physiology and Chronic Health Evaluation II score (P = .034), Marshall score (P = .01), and length of intensive care unit stay (10.5 ± 3.2 vs 12.2 ± 2.8 days; P = .012). However, the 28-day mortality rate was not significantly different between the SFI (20.5%; 16/78) and placebo groups (27.8%; ?22/79; P = .28).Conclusion
These findings suggest that SFI can enhance the cellular immunity of patients with septic shock and could be a promising adjunctive treatment for patients with septic shock. 相似文献19.

This retrospective cohort study included non-traumatic adult patients with ARF and mechanical ventilation support in the ED of a tertiary university hospital in Taiwan from January 1, 2013, to August 31, 2013. Clinical data were extracted from chart records. The primary and secondary outcome measures were a prolonged hospital stay (>30 days) and the in-hospital crude mortality within 90 days, respectively.Results
For 267 eligible patients (age range 21.0-98.0 years, mean 70.5 ± 15.1 years; male 184, 68.9%), multivariate analysis was used to determine the significant adverse effects of an ED stay >1.0 hour on in-hospital crude mortality (odds ratio 2.19, P < .05), which was thus defined as delayed ICU admission. In-hospital mortality significantly differed between patients with delayed ICU admission and those without delayed admission, as revealed by the Kaplan-Meier survival curves (P < .05). Moreover, a linear-by-linear correlation was observed between the length of ICU waiting time in the ED and the lengths of total hospital stay (r = 0.152, P < .05), ICU stay (r = 0.148, P < .05), and ventilator support (r = 0.222, P < .05).Conclusions
For patients with ARF who required mechanical ventilation support and intensive care, a delayed ICU admission more than 1.0 hour is a strong determinant of mortality and is associated with a longer ICU stay and a longer need for ventilation. 相似文献20.
