Background
Cardiac arrest caused by accidental hypothermia is a rare phenomenon with a significant mortality rate if untreated. The consensus is that these patients should be rewarmed with extracorporeal life support (ECLS) with the potential for excellent survival and neurologic outcomes. However, given the lack of robust data and clinical trials, the optimal management of such patients remains elusive.Objective
In this single-center study, we looked at the outcomes of all adult patients undergoing salvage ECLS for cardiac arrest caused by accidental hypothermia over a 10-year period from June 2006 to June 2016.Methods
These data were obtained from the Royal Infirmary of Edinburgh cardiothoracic surgery database. The patients' hard copy case notes, TrakCare (InterSystems Corp, Cambridge, MA), picture archiving and communications system (PACS), and WardWatcher databases were used to cross-check the accuracy of the acquired data.Results
Eleven patients met the inclusion criteria. The etiology of hypothermia was exposure to cold air (64%) and cold water immersion (36%). Two (18%) were treated with extracorporeal membrane oxygenation and the rest with cardiopulmonary bypass. The mean age was 51 years (range 32–73), and the mean core body temperature on admission was 20.6°C (range <18–24°C). The overall survival rate to hospital discharge was 72%, with 75% of survivors having no chronic neurologic impairment.Conclusion
Our case series shows the remarkable salvageability of patients suffering prolonged cardiac arrest caused by accidental hypothermia, particularly in the absence of asphyxia, trauma, or severe hyperkalemia. ECLS is a safe and effective rewarming treatment and should be used to aggressively manage this patient group. 相似文献2.

Background
We utilized a porcine cardiac arrest model to compare early sequential hypothermia (ESH) with delayed hypothermia (DH) and no hypothermia (NH) to investigate the different effects on cerebral function after resuscitation.Methods
After return of spontaneous circulation (ROSC), resuscitated 24 pigs divided into three groups. The ESH group implemented early sequential hypothermia immediately, and the DH group implemented delayed hypothermia at 1 h after ROSC. The core temperature, hemodynamic parameters and oxygen metabolism were recorded. Cerebral metabolism variables and neurotransmitter in the extracellular fluid were collected through the microdialysis tubes. The bloods were analyzed for venous jugular bulb oxygen saturation, lactate and neuron specific nolase. The cerebral function was evaluated using the cerebral performance category and neurologic deficit score at 72 h after ROSC and cerebral histology in the right posterior frontal lobe were collected.Results
ESH reached the target temperature earlier and showed more favorable outcomes of neurological function than DH. Specifically, early sequential hypothermia reduced cerebral oxygen and energy consumption and decreased extracellular accumulation of neurotransmitters after resuscitation and protected the integrity of the BBB during reperfusion.Conclusions
Early sequential hypothermia could increase the protection of neurological function after resuscitation and produce better neurological outcomes.The institutional protocol number: 2010-D-013. 相似文献3.

Background
Accurate temperature readings, often obtained rectally, are an important part of the initial evaluation of pediatric patients in the Emergency Department. Temporal artery thermometry (TAT) is one way to noninvasively measure temperature. We sought to compare the accuracy of axillary and temporal artery temperatures compared to rectal.Methods
This prospective study included children age 0–36 months presenting to the Emergency Department of a large military treatment facility. Rectal, axillary, and temporal artery temperatures were obtained. Test characteristics (sensitivity, specificity, NPV, PPV) were reported. The effect of cutoff values 99.9 °F, 100.4 °F, and 102.2 °F on test characteristics were also evaluated.Results
The sensitivities of axillary and temporal artery thermometry to detect rectal fever is 11.5% and 61.5% respectively. Cutoff values did not significantly alter test characteristics. In this study, temporal artery thermometry was 0.2 °C lower than rectal temperature, axillary measurement was 0.9 °C below the reference standard. Mean temperature difference in the febrile group between TAT and rectal thermometry was > 0.5 °C compared with a mean temperature difference 0.05 °C in afebrile patients.Conclusion
The findings of our study do not support using axillary thermometry to screen pediatric patients for fever in the emergency department. TAT cannot be recommended as a rectal thermometry replacement where height and duration of fever are used in pediatric disease prediction models. TAT may have a role in screening for fever in the appropriate pediatric patient population like primary orthopedic or trauma presentations where the balance between device precision, data capture and patient comfort may favor use of TAT. 相似文献4.

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5.

Objective
To assess the effectiveness of bracing in adult with scoliosis.Design
Retrospective cohort study.Setting
Outpatients followed in 2 tertiary care hospitals.Participants
Adults (N=38) with nonoperated progressive idiopathic or degenerative scoliosis treated by custom-molded lumbar-sacral orthoses, with a minimum follow-up time of 10 years before bracing and 5 years after bracing. Progression was defined as a variation in Cobb angle ≥10° between the first and the last radiograph before bracing. The brace was prescribed to be worn for a minimum of 6h/d.Interventions
Not applicable.Main Outcome Measure
Rate of progression of the Cobb angle before and after bracing measured on upright 3-ft full-spine radiographs.Results
At the moment of bracing, the mean age was 61.3±8.2 years, and the mean Cobb angle was 49.6°±17.7°. The mean follow-up time was 22.0±11.1 years before bracing and 8.7±3.3 years after bracing. For both types of scoliosis, the rate of progression decreased from 1.28°±.79°/y before to .21°±.43°/y after bracing (P<.0001). For degenerative and idiopathic scoliosis, it dropped from 1.47°±.83°/y before to .24°±.43°/y after bracing (P<.0001) and .70°±.06°/y before to .24°±.43°/y after bracing (P=.03), respectively.Conclusions
For the first time, to our knowledge, this study suggests that underarm bracing may be effective in slowing down the rate of progression in adult scoliosis. Further prospective studies are needed to confirm these results. 相似文献6.

Objective
The aim of this study was to determine if a needle is able to reach the cervical multifidus during the application of dry needling or acupuncture.Methods
Dry needling and ultrasound imaging of cervical multifidi was conducted on 5 patients (age: 32 ± 5 years) with mechanical neck pain and on 2 fresh cadavers (age: 64 ± 1 years). Dry needling was done using a needle of 40 mm in length inserted perpendicular to the skin about 1 cm lateral to the spinous process at C3-C4. The needle was advanced from a posterior to anterior direction into the cervical multifidus with a slight inferior-medial angle (approximately 10°) to reach the vertebra lamina. For the cadaveric study, the multifidus was isolated by carefully resecting the superficial posterior cervical muscles: trapezius, splenius, and semispinalis. For the ultrasonographic study, a convex transducer was placed transversely over C3-C4 after the insertion of the needle into the muscle.Results
The results of both the cadaveric and ultrasonic studies found that the needle does pierce the cervical multifidus muscle during insertion and that the tip of the needle rests properly against the vertebral laminae, thereby guarding the sensitive underlying spinal structures from damage.Conclusion
This anatomical and ultrasound imaging study supports that dry needling of the cervical multifidus could be conducted clinically. 相似文献7.

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8.

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10.

Introduction
Development of technologies to reduce transfusion risks of infectious diseases is a major characteristic of hemotherapy. Thus, each donation undergoes clinical and serological screening tests to ensure the donated blood do not offer risks to the receiver.Objective
Evaluate the prevalence of positive serology in blood donations rejected by Hemobanco (Curitiba – PR) in the period ranging from January 2003 to December 2012.Methodology
During the period studied, we observed the total number of donations and its division according to gender. We also analyzed the number of rejected donations due to seropositivity, considering the diseases investigated routinely in blood banks in Brazil, and the frequency of discards according to age groups.Results
Within the period studied, 399,280 donations were performed. 62.0% donors were male. Comparing 2003 to 2012, we noticed a significant decrease of discards, from 10.2% to 5.0%, respectively. There was a reduction of seropositivity for HIV, HBsAg and anti-HBc and an increase for Chagas Disease, hepatitis C, syphilis and HTLV. The age group with the highest prevalence for discards changed: it used to be the 40–59 years old group in 2003, and became the 20–39 years old group in 2012.Conclusion
There was an increase in the number of donations in Hemobanco and a decrease in total discards due to seropositive donations. Most donors were male. The most prevalent cause of discards only amongst seropositive donation discards is seropositivity for anti-HBc. There was a significant increase of donors aged between 20 and 39 years old. 相似文献11.

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12.

Objectives
This investigation compared indirect 3-dimensional angular kinematics (position, velocity, and acceleration) of the lumbar spine for 2 different high-velocity, low-amplitude (HVLA) spinal manipulation procedures (lumbar spinous pull or push), and altered initial patient lower limb posture.Methods
Twenty-four participants underwent 6 HVLA procedures directed toward the presumed L4 vertebra, reflecting each combination of 2 variants of a spinal manipulation application technique (spinous pull and push) and 3 initial hip flexion angles (0°, 45°, and 90°) applied using a right lateral recumbent patient position. All contact forces and moments between the patient and the external environment, as well as 3-dimensional kinematics of the patient’s pelvis and thorax, were recorded. Lumbar spine angular positions, velocities, and accelerations were analyzed within the preload and impulse stages of each HVLA trial.Results
Lumbar spine left axial rotation was greater for the pull HVLA. The pull HVLA also generated a greater maximum (leftward) and lower minimum (rightward) axial rotation velocity and deceleration and greater leftward and rightward lateral bend velocities, acceleration, and deceleration components. Not flexing the hip produced the greatest amount of extension, as well as the lowest axial rotation and maximum axial rotation acceleration during the impulse.Conclusions
This investigation provides basic kinematic information for clinicians to understand the similarities and differences between 2 HVLA side-lying manipulations in the lumbar spine. Use of these findings and novel technology can drive future research initiatives that can both affect clinical decision making and influence teaching environments surrounding spinal manipulative therapy skill acquisition. 相似文献13.

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14.

Background
The prepared procedure for universal plasma in the Chinese population has been developed. However, the immunological safety with the level of antibodies, soluble immune complexes and complements is necessary to investigate.Methods
The universal plasma was pooled at the optimal ratio of A:B:AB = 6:2.5:1.5 at 22 °C for 1 hour. The titer of IgM antibodies was detected by saline agglutination, and the titer of IgG antibodies was detected by a Polybrene test after IgM destroyed by 2-mereaptoethanol. The hemolysis extent of RBC was investigated by an extracorporal hemolysis test, and the concentration of free-hemoglobin was determined by the ortho-tolidine method. The levels of CIC-C1q, C3b and TCC (C5-9) were tested using an enzyme linked immunosorbent assay (ELISA).Results
The titer of IgM and IgG in universal plasma was lower than 2 and 4, respectively. The hemolysis of the universal plasma with A, B and AB group RBCs was negative with values of 5.5, 6.8 and 5.7, respectively. The level of CIC-C1q and TCC (C5-9) in universal plasma was comparable to that in A or B type pooled plasma, but CIC-C1q was lower than that and TCC (C5-9) was higher than that in AB type pooled plasma. The level of complement C3b was comparable to that in A type pooled plasma, but lower than that in B type pooled plasma and higher than that in AB type pooled plasma.Conclusion
The results of this study demonstrated that the immunological levels were within an acceptable range and confirmed the safety in vitro. 相似文献15.

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16.

Background
Disparities exist in the care children receive in the emergency department (ED) based on their insurance type. It is unknown if these differences exist among children transferred from outside EDs to pediatric tertiary care EDs.Objective
To compare reasons for transfer and services received at pediatric tertiary care EDs between children with private and public insurance.Methods
We performed a secondary analysis of a multicenter survey of ED providers transferring patients to pediatric tertiary care EDs in three major U.S. cities. Risk differences (RD) and 95% confidence intervals (CI) were calculated to compare reasons for transfer and care received at pediatric tertiary care EDs based on insurance type.Results
There were 561 surveys completed by transferring providers describing reasons for transfer to pediatric tertiary care EDs with 52.2% of patients with private insurance and 47.8% with public insurance. We found no significant differences between privately and publicly insured children in reason for transfer for subspecialty consultation or need for admission. We found no significant differences in frequency of admission, radiologic studies, or ED procedures at the receiving facilities. However, a greater proportion of privately insured children had a subspecialty consultation at receiving facilities compared to publicly insured children (RD 9.7, 95% CI 2.0 to 17.4).Conclusions
Transferred pediatric patients with private insurance were more likely to have subspecialty consultations than children with public insurance. Further studies are needed to better characterize the interplay between patients' insurance type and both the request for, and the provision of, ED subspecialty consultations. 相似文献17.

Objectives
The aim of this study was to assess the thorax-rib static method (TRSM), a palpation method for locating the seventh cervical spinous process (C7SP), and to report clinical data on the accuracy of this method and that of the neck flexion-extension method (FEM), using radiography as the gold standard.Methods
A single-blinded, cross-sectional diagnostic accuracy study was conducted. One hundred and one participants from a primary-to-tertiary health care center (63 men, 56 ± 17 years of age) had their neck palpated using the FEM and the TRSM. A single examiner performed both the FEM and TRSM in a random sequence. Radiopaque markers were placed at each location with the aid of an ultraviolet lamp. Participants underwent chest radiography for assessment of the superimposed inner body structure, which was located by using either the FEM or the TRSM.Results
Accuracy in identifying the C7SP was 18% and 33% (P = .013) with use of the FEM and the TRSM, respectively. The cumulative accuracy considering both caudal and cephalic directions (C7SP ± 1SP) increased to 58% and 81% (P = .001) with use of the FEM and the TRSM, respectively. Age had a significant effect on the accuracy of FEM (P = .027) but not on the accuracy of TRSM (P = .939). Sex, body mass, body height, and body mass index had no significant effects on the accuracy of both the FEM (P = .209 or higher) and the TRSM (P = .265 or higher).Conclusions
The TRMS located the C7SP more accurately compared with the FEM at any given level of anatomic detail, although both still underperformed in terms of acceptable accuracy for a clinical setting. 相似文献18.

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19.

Background
Mild induced hypothermia (MIH) was introduced for post cardiac arrest care in Sweden in 2003, based on two clinical trials. This retrospective study evaluated its association with 30-day survival after out-of-hospital cardiac arrest (OHCA) in a Swedish community from 2003 to 2015.Methods
Out of 3680 patients with OHCA, 1100 were hospitalized after return of spontaneous circulation and 871 patients who remained unconscious were included in the analysis. Prehospital data were extracted from the Swedish Registry of Cardiopulmonary Resuscitation and in-hospital data were extracted from clinical records. Propensity score analysis on complete data sets and multivariable logistic regression with multiple imputations to compensate for missing data were performed.Results
Unadjusted 30-day survival was 23.5%; 37% in 386/871 (44%) MIH treated and 13% in 485/871 (56%) non-MIH treated patients. Unadjusted odds ratio (OR) for 30-day survival in patients treated with MIH compared to non-MIH treated patients was 3.79 (95% CI 2.71–5.29; p < 0.0001). Using stratified propensity score analysis and in addition adjusting for in-hospital factors, 30-day survival was not significantly different in patients treated with MIH compared to non-MIH treated patients; OR 1.33 (95% CI 0.83–2.15; p = 0.24). Using multiple imputations to handle missing data yielded a similar adjusted OR of 1.40 (95% CI 0.88–2.22; p = 0.15). Good neurologic outcome at hospital discharge was seen in 82% of patients discharged alive.Conclusion
Treatment with MIH was not significantly associated with increased 30-day survival in patients remaining unconscious after OHCA when adjusting for potential confounders. 相似文献20.
