Rapid Characterization of Undeclared Pharmaceuticals in Herbal Preparations by Ambient Ionization Mass Spectrometry for Emergency Care.

In Asia, some herbal preparations have been found to be adulterated with undeclared synthetic medicines to increase their therapeutic efficiency. Many of these adulterants were found to be toxic when overdosed and have been documented to bring about severe, even life-threatening acute poisoning events. The objective of this study is to develop a rapid and sensitive ambient ionization mass spectrometric platform to characterize the undeclared toxic adulterated ingredients in herbal preparations. Several common adulterants were spiked into different herbal preparations and human sera to simulate the clinical conditions of acute poisoning. They were then sampled with a metallic probe and analyzed by the thermal desorption-electrospray ionization mass spectrometry. The experimental parameters including sensitivity, specificity, accuracy, and turnaround time were prudently optimized in this study. Since tedious and time-consuming pretreatment of the sample is unnecessary, the toxic adulterants could be characterized within 60 s. The results can help emergency physicians to make clinical judgments and prescribe appropriate antidotes or supportive treatment in a time-sensitive manner.

Clinical efficacy of Kuanxiong aerosol for patients with prehospital chest pain: A randomized controlled trial.

BACKGROUND: Kuanxiong Aerosol (KXA)(CardioVent®), consisting of Asarum sieboldii Miq. oil, Santalum album L. oil, Alpinia officinarum Hance oil, Piper longum L. oil and borneol, seems to relieve the symptoms of chest pain and serve as a supplementary treatment for prehospital chest pain in emergency department. STYLE OF THE STUDY: This randomized controlled trial aimed to determine the clinical effect and safety of KXA for patients with prehospital chest pain. METHODS: A total of 200 patients were recruited from Guangdong Provincial Hospital of Chinese Medicine and randomly divided into KXA group (n = 100) and Nitroglycerin Aerosol (NA) group (n = 100) by SAS 9.2 software. All patients were treated with standardized Western medicine according to the pre-hospital procedure. The experimental group and NA group was additionally treated with KXA and NA respectively. The primary outcome was the relieving time of prehospital chest pain (presented as relief rate) after first-time treatment. The secondary outcomes included the evaluation of chest pain (NRS scores, degree of chest pain, frequency of chest pain after first-time treatment), efficacy in follow-up time (the frequency of average aerosol use, emergency department visits, 120 calls, medical observations and hospitalization at 4 weeks, 8 weeks, 12 weeks), alleviation of chest pain (Seattle angina questionnaire, chest pain occurrence, and degree of chest pain at 12-weeks treatment) and the change of TCM symptoms before and after 12-weeks treatment. In addition, the safety of KXA was also assessed by the occurrence of adverse events. The database was created using Epidata software, and statistical analysis was conducted by SPSS 23.0 software. RESULTS: A total of 194 participants finally completed the trial, the results showed that after first-time treatment, KXA had a higher relief rate (72.2%) of chest pain within 30 min than that of NA group (59.4%, p = 0.038), KXA group had a lower degree of chest pain (p = 0.005), lower NRS score (p = 0.011) and higher reduction of NRS score (p = 0.005) than the NA. In the follow-up period, KXA group decreased the frequency of 120 call better than that of NA group at 4 weeks (p = 0.040), but KXA had a similar efficacy as NA in the improvement on the of frequency of chest pain, aerosol use, emergency department visits, 120 call, medical observation and hospitalization at 4 weeks, 8 weeks and 12 weeks (p>0.05). There also had no difference between the two groups on the occurrence of chest pain, degree of chest pain, physical limitation, angina stability, treatment satisfaction, and disease perception between the two groups at 12 weeks (p>0.05). In addition, KXA and NA both improved the patient's chest pain, but not the TCM symptoms. In terms of safety, KXA showed similar safety as NA in this study. CONCLUSIONS: KXA relieved prehospital chest pain faster than NA and had a better remission effect on the prehospital chest pain than that of the NA group in short-period. In long-period, KXA showed similar efficacy on the improvement of prehospital chest pain as NA. KXA may be a safe and reliable therapy for prehospital chest pain.

[Digital systems to support emergency medical service : A Germany-wide cross-sectional survey on current availability, utilization and existing challenges]. / Digitale Systeme zur Unterstützung von präklinischen Notfalleinsätzen : Deutschlandweite Querschnittserhebung zu Verfügbarkeit, Nutzung und bestehenden Herausforderungen.

BACKGROUND AND OBJECTIVE: Increasing requirements for documentation, cross-sectoral communication and quality management are leading to increased organizational effort in emergency medical services (EMS). On the one hand, the use of digital information systems in prehospital settings can help to support emergency physicians and paramedics in these tasks and on the other hand, it opens new treatment options such as telemedical care for patients. This work attempts to provide a comprehensive picture of the current use of digital systems for ambulance services in Germany. To do so, the study investigated how widespread various information and communication systems currently are at local EMS stations and ambulances, how they are used by emergency personnel, how they are assessed by users and what challenges currently exist for further expansion and greater acceptance of the users. MATERIAL AND METHODS: The cross-sectional study was conducted as a nationwide, exploratory online survey among emergency physicians and paramedic professionals in July and August 2020 covering 24 different questions. Participation was called for on the Internet, at EMS stations and in hospital emergency departments. Subsequent data analysis was performed using descriptive statistical methods. Solutions considered included digital documentation and hospital prenotification, interdisciplinary care capacity notification, real-time telehealth services and digital radio units. RESULTS: In total, 821 responses of participants from 481 different EMS stations from 382 cities nationwide were included in the evaluation. The availability of the 16 systems surveyed varies significantly throughout Germany, depending on the federal state and application. While basic equipment such as radio units or navigation devices are available on almost all surveyed ambulances, the share which has real-time telehealth applications at their disposal is just 6%. A proportion of 72% reported the usage of any type of digital documentation and 41% used a digital tool for prenotification of emergency rooms in at least one hospital. The emergency staff surveyed were generally open to new technologies and resulting possibilities, such as having an electronic patient care record or transmitting patient data digitally to emergency room. Almost all participants see a benefit in the use of information technology in ambulance service, although slightly more than half considered current implementation as unsatisfactory. Challenges are particularly evident with regard to reliability, hardware, useability and interoperability with third parties, such as dispatch centres and hospitals. CONCLUSION: Although information technology systems in German EMS are no longer in their infancy, there is still a long way to go before prehospital emergency care can be considered as extensively and adequately digitalized. A more holistic perspective and networked implementation of all systems and processes involved in emergency response operations can help improve and further spread digital solutions for prehospital emergency care. Incorporating field experience into the development process could contribute to increasing functionality and user acceptance.

Facility and care provider emergency preparedness for neonatal resuscitation in Kano, Nigeria.

INTRODUCTION: The knowledge, attitude, and practice of emergency neonatal resuscitation are critical requirements in any facility that offers obstetric and neonatal services. This study aims to conduct a needs assessment survey and obtain individual and facility-level data on expertise and readiness for neonatal resuscitation. We hypothesize that neonatal emergency preparedness among healthcare providers in Kano, Nigeria is associated with the level of knowledge, attitudinal disposition, practice and equipment availability at the facility level. METHODS: A semi-structured, self-administered questionnaire was administered to a cross-section of health providers directly involved with neonatal care (n = 112) and attending a neonatal resuscitation workshop in Kano state. Information regarding knowledge, attitude, practice and facility preparedness for neonatal resuscitation was obtained. Bloom's cut-off score and a validated basic emergency obstetric and neonatal care assessment tool were adopted to categorize outcomes. Multivariable logistic regression was employed to determine independent predictors of knowledge and practice. RESULTS: Almost half (48% and 42% respectively) of the respondents reported average level of self-assessed knowledge and comfort during resuscitation. Only 7% (95% CI:3.2-13.7) and 5% (95% CI:2.0-11.4) of health providers demonstrated good knowledge and practice scores respectively, with an overall facility preparedness of 46%. Respondents' profession as a physician compared to nurses and midwives predicted good knowledge (aOR = 0.08, 95% CI: 0.01-0.69; p = 0.01), but not practice. CONCLUSION: Healthcare provider's knowledge and practice including facility preparedness for emergency neonatal resuscitation were suboptimal, despite the respondents' relatively high self-assessed attitudinal perception. Physicians demonstrated higher knowledge compared to other health professionals. The low level of respondents' awareness, practice, and facility readiness suggest the current weak state of secondary health systems in Kano.

[Management of COVID-19 mass casualty incidents in nursing and retirement homes]. / Managementstrategie für den Massenanfall von Erkrankten/Infizierten in Alten- und Pflegeheimen im Kontext der COVID-19-Pandemie.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, outbreaks in inpatient care facilities, which grow into a large-scale emergency scenario, are frequently observed. A standardized procedure analogous to algorithms for mass casualty incidents (MCI) is lacking. METHODS: Based on a case report and the literature, the authors present a management strategy for infectious MCI during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and distinguish it from traumatic MCI deployment tactics. RESULTS: This management strategy can be divided into three phases, beginning with the acute emergency response including triage, stabilization of critical patients, and transport of patients requiring hospitalization. Phase 2 involves securing the facility's operational readiness, or housing residents elsewhere in case staff are infected or quarantined to a relevant degree. Phase 3 marks the return to regular operations. DISCUSSION: Phase 1 is based on usual MCI principles, phase 2 on hospital crisis management. Avoiding evacuation of residents to relieve hospitals is an important operational objective. The lack of mission and training experience with such situations, the limited applicability of established triage algorithms, and the need to coordinate a large number of participants pose challenges. CONCLUSION: This strategic model offers a practical, holistic approach to the management of infectious mass casualty scenarios in nursing facilities.

MANAGEMENT OF ENDOCRINE DISEASE: Postsurgical hypoparathyroidism: current treatments and future prospects for parathyroid allotransplantation.

BACKGROUND: Permanent postsurgical hypoparathyroidism (POSH) is a major complication of anterior neck surgery in general and of thyroid surgery in particular. Depending on diagnostic criteria, up to 10% of patients undergoing bilateral thyroid surgery develop POSH. This leads to a multitude of symptoms that decrease the quality of life and burden the healthcare provision through complex needs for medication and treatment of specific complications, such as seizures and laryngospasm. METHODS: Narrative review of current medical treatments for POSH and of the experience accumulated with parathyroid allotransplantation. RESULTS: In most patients, POSH is controlled with regular use of calcium supplements and active vitamin D analogues but a significant proportion of patients continue to experience severe symptoms requiring repeated emergency admissions. Replacement therapy with synthetic PTH compounds (PTH1-34, Natpara® and PTH1-84, teriparatide, Forsteo®) has been assessed in multicentre trials, but the use of this medication is restricted by costs and concerns related to the risk of development of osteosarcoma. Based on recent case reports of successful allotransplantation of parathyroid tissue between siblings, there is renewed interest in this technique. Data on selection of donors, parathyroid cell preparation before allotransplantation, site and timing of transplantation, need for immunosuppression and long-term outcomes are reviewed. CONCLUSION: A prospective trial to assess the efficacy of parathyroid allotransplantation in patients with severely symptomatic protracted post-surgical hypoparathyroidism is warranted.

Economic Analysis of Mobile Integrated Health Care Delivered by Emergency Medical Services Paramedic Teams.

Importance: Mobile integrated health care (MIH) is a new model of community-based health care to provide on-site urgent or nonurgent care. Niagara emergency medical services (NEMS) started MIH in 2018 to serve the Niagara region of Ontario, Canada. However, its economic impact is unknown. Objective: To compare time on task and cost between MIH and ambulance delivered by NEMS from a public payer's perspective. Design, Setting, and Participants: This economic evaluation was an analysis of the NEMS databases regarding responses to emergency calls by the NEMS from 2016 to 2019. Emergency calls serviced by MIH in 2018 to 2019 were used as an intervention cohort. Propensity score matching was used to identify a 1:1 matched cohort of calls serviced by regular ambulance response for the same period and 2 years prior. Statistical analyses were performed from January to April 2020. Exposures: MIH compared with matched ambulance services. Main Outcomes and Measures: The main outcomes were the time on task (including time on scene and time at hospital) and costs. Costs were calculated in 2019 Canadian dollars using cost per minute and compared with the 3 ambulance cohorts. Results: In 2018 to 2019, there were 1740 calls serviced by MIH for which a matched ambulance cohort was identified for the same period and 2 years prior. The mean (SD) time on task was 72.7 (51.0) minutes for MIH, compared with 84.1 (52.0) minutes, 84.3 (54.1) minutes, and 79.4 (42.0) minutes for matched ambulance in 2018 to 2019, 2017 to 2018, and 2016 to 2017, respectively. Of calls serviced by MIH, 498 (28.6%) required ED transport (ie, after MIH team assessment, transport to ED was deemed to be necessary or demanded by the patient), compared with 1300 (74.7%) calls serviced by ambulance in 2018 to 2019, 1294 (74.4%) in 2017 to 2018, and 1359 (78.1%) in 2016 to 2017. The mean (SD) total cost per 1000 calls was $122 760 ($78 635) for MIH compared with $294 336 ($97 245), $299 797 ($104 456), and $297 269 ($81 144) for regular ambulance responses in the 3 matched cohorts, respectively. Conclusions and Relevance: Compared with regular ambulance response, MIH was associated with a substantial reduction in the proportion of patients transported to the ED, leading to a substantial saving in total costs. This finding suggests that the MIH model is a promising and viable solution to meeting urgent health care needs in the community, while substantially improving the use of scarce health care resources.

Introduction: At Julián Grimau Teaching Polyclinic in Arroyo Naranjo municipality, ammonia is a risk of chemical emergency that can affect part of the population that it serves to. Hence, it is necessary for the medical response to these situations to take into account the specificities of the institution and its systemic character. Objective: Propose a medical response system for chemical emergency by ammonia in Julián Grimau Teaching Polyclinic. Methods: A research was carried out on health systems and services, from September 2017 to December 2018, in Julián Grimau Teaching Polyclinic. A documentary analysis related to medical actions in chemical emergencies was conducted in primary health care's level. In addition, the following methods were used: structural-functional systemic for the design of the system, and the key informant for its concretion. Result: Practical- theoretical premises were stated and the polyclinic's response system was designed, in its alarm phase, which assumed two subsystems: the emergency one, formed by the components: reception, special treatment, classification and emergency treatment; and, the assurance one, consisting of human, material and diagnostic components. Conclusions: The organizational systemic structure of the medical response to chemical emergencies by ammonia in the Julián Grimau Polyclinic is based on its own theoretical-practical premises that determine the institutional holistic structure to establish the process from a systemic-structural-functional approach. Hence, the proposed system for the alarm phase is flexible, objective, participatory, timely, adequate and selective(AU)

Acute Care Treatment of Migraine.

OBJECTIVE: Migraine is a chronic neurological disease involving the brain and its vasculature, typically characterized by recurrent attacks of moderate or severe throbbing headache, accompanied by sensitivity to light and sound, and associated with nausea, vomiting, and inability to move due to worsening of pain. About 30% of migraineurs have some type of aura, most often visual. Migraine attacks, if untreated or suboptimally treated, usually result in significant disability, requiring bed rest and resulting in poor quality of life. Increased frequency of attacks and overuse of acute care medication are significant risks for chronification, resulting in the transformation of episodic migraine into chronic migraine. We aim to review most acute care treatments for migraine. METHODS: Current treatment options for migraine attacks were reviewed from the selected literature and combined with our clinical experience. RESULTS: Current acute treatment options for migraine attacks include over-the-counter analgesics, at times combined with caffeine, nonsteroidal anti-inflammatory medications, opioids, and migraine-specific medications such as triptans and ergots. In the near future, we will probably have 3 gepants (small-molecule calcitonin gene-related peptide [CGRP] receptor antagonists). The first one was just approved in the United States. A ditan acting as a stimulator of 5-HT1F receptors, was also just approved by the FDA. Stimulation of the trigeminal, vagal, occipital, and even upper arm peripheral nerves through electrical nerve stimulation devices and magnetic stimulation devices are available as alternative, nondrug treatment options. Several devices have already been FDA-allowed for treatment in the United States and/or approved elsewhere, and others will follow soon. Behavioral medicine techniques such as biofeedback training and mindfulness have been available for some time and are often helpful. CONCLUSION: A wide variety of acute care options to treat migraine are available, and others will soon be and will herein be described in further detail. Some medications have been approved by regulatory authorities in countries other than the United States, and some devices have been given a CE Mark in Europe.

A systematic review of pre-hospital shoulder reduction techniques for anterior shoulder dislocation and the effect on patient return to function.

PURPOSE: The majority of acute anterior shoulder dislocations are sustained during sports and wilderness activities. The management of acute dislocations in the pre-hospital setting is currently without guidelines based on the evidence. The study aims to assess the risk of acute complications in pre-hospital shoulder reduction and identify which pre-hospital reduction technique has the highest success rate in the published literature. METHODS: The involved databases were Allied and Complementary Medicine, CENTRAL, CINAHL, Cochrane Database of Systematic Reviews, Embase, Europe PMC, Ovid MEDLINE®, Pedro, Proquest, Trip, and World Health Organization International Clinical Trials Registry platform. Only original research of high methodological quality was included, which was defined by the recently developed assessment tool-assessing the methodological quality of published papers (AMQPP) and investigated the management of acute anterior shoulder dislocations in the pre-hospital setting. RESULTS: Two hundred and ninety-eight articles were identified and screened. A full text review was performed on 40 articles. Four articles published between 2015 and 2018 met the inclusion criteria. A total of 181 patients were included with the study duration ranging from 6 to 60 months. All studies reported zero immediate complication following pre-hospital reduction and there were no documented subsequent adverse events regardless of the technique used. Prompt resolution of neurological symptoms was observed following the early and successful pre-hospital reduction. First attempt success rate, when performed by skilled practitioners, ranged from 72.3% to 94.9%. CONCLUSION: Pre-hospital shoulder reduction appears to be a safe and feasible option when carried out with the appropriate expertise. A novel reduction technique adapted from the mountain medicine diploma course at the University of Paris North was found to have the highest first attempt reduction success rate of 94.9%. Other techniques described in the literature included Hippocratic, Stimson's, Counter-traction and external rotation with the success rates ranging from 54% to 71.7%.

A manual reduction of hernia under analgesia/sedation (Taxis) in the acute inguinal hernia: a useful technique in COVID-19 times to reduce the need for emergency surgery-a literature review.

BACKGROUND: Acute IH is a common surgical presentation. Despite new guidelines being published recently, a number of important questions remained unanswered including the role of taxis, as initial non-operative management. This is particularly relevant now due to the possibility of a lack of immediate surgical care as a result of COVID-19. The aim of this review is to assess the role of taxis in the management of emergency inguinal hernias. METHODS: A review of the literature was undertaken. Available literature published until March 2019 was obtained and reviewed. 32,021 papers were identified, only 9 were of sufficient value to be used. RESULTS: There was a large discrepancy in the terminology of incarcerated/strangulated used. Taxis can be safely attempted early after the onset of symptoms and is effective in about 70% of patients. The possibility of reduction en-mass should be kept in mind. Definitive surgery to repair the hernia can be delayed by weeks until such time as surgery can be safely arranged. CONCLUSIONS: The use of taxis in emergency inguinal hernia is a useful first line of treatment in areas or situations where surgical care is not immediately available, including the COVID-19 pandemic. Emergency surgery remains the mainstay of management in the strangulated hernia setting.

Forgot calcium? Admission ionized-calcium in two civilian randomized controlled trials of prehospital plasma for traumatic hemorrhagic shock.

BACKGROUND: Randomized clinical trials (RCTs) support the use of prehospital plasma in traumatic hemorrhagic shock, especially in long transports. The citrate added to plasma binds with calcium, yet most prehospital trauma protocols have no guidelines for calcium replacement. We reviewed the experience of two recent prehospital plasma RCTs regarding admission ionized-calcium (i-Ca) blood levels and its impact on survival. We hypothesized that prehospital plasma is associated with hypocalcemia, which in turn is associated with lower survival. METHODS: We studied patients enrolled in two institutions participating in prehospital plasma RCTs (control, standard of care; experimental, plasma), with i-Ca collected before calcium supplementation. Adults with traumatic hemorrhagic shock (systolic blood pressure ≤70 mm Hg or 71-90 mm Hg + heart rate ≥108 bpm) were eligible. We use generalized linear mixed models with random intercepts and Cox proportional hazards models with robust standard errors to account for clustered data by institution. Hypocalcemia was defined as i-Ca of 1.0 mmol/L or less. RESULTS: Of 160 subjects (76% men), 48% received prehospital plasma (median age, 40 years [interquartile range, 28-53 years]) and 71% suffered blunt trauma (median Injury Severity Score [ISS], 22 [interquartile range, 17-34]). Prehospital plasma and control patients were similar regarding age, sex, ISS, blunt mechanism, and brain injury. Prehospital plasma recipients had significantly higher rates of hypocalcemia compared with controls (53% vs. 36%; adjusted relative risk, 1.48; 95% confidence interval [CI], 1.03-2.12; p = 0.03). Severe hypocalcemia was significantly associated with decreased survival (adjusted hazard ratio, 1.07; 95% CI, 1.02-1.13; p = 0.01) and massive transfusion (adjusted relative risk, 2.70; 95% CI, 1.13-6.46; p = 0.03), after adjustment for confounders (randomization group, age, ISS, and shock index). CONCLUSION: Prehospital plasma in civilian trauma is associated with hypocalcemia, which in turn predicts lower survival and massive transfusion. These data underscore the need for explicit calcium supplementation guidelines in prehospital hemotherapy. LEVEL OF EVIDENCE: Therapeutic, level II.

Enhancing CPR During Transition From Prehospital to Emergency Department: A QI Initiative.

BACKGROUND AND OBJECTIVES: High-quality cardiopulmonary resuscitation (CPR) increases the likelihood of survival of pediatric out-of-hospital cardiac arrest (OHCA). Maintenance of high-quality CPR during transition of care between prehospital and pediatric emergency department (PED) providers is challenging. Our objective for this initiative was to minimize pauses in compressions, in alignment with American Heart Association recommendations, for patients with OHCA during the handoffs from prehospital to PED providers. We aimed to decrease interruptions in compressions during the first 2 minutes of PED care from 17 seconds (baseline data) to 10 seconds over 12 months. Our secondary aims were to decrease the length of the longest pause in compressions to <10 seconds and eliminate encounters in which time to defibrillator pad placement was >120 seconds. METHODS: Our multidisciplinary team outlined our theory for improvement and designed interventions aimed at key drivers. Interventions included specific roles and responsibilities, CPR handoff choreography, and empowerment of frontline providers. Data were abstracted from video recordings of patients with OHCA receiving manual CPR on arrival. RESULTS: We analyzed 33 encounters between March 2018 and July 2019. We decreased total interruptions from 17 to 12 seconds during the first 2 minutes and decreased the time of the longest single pause from 14 to 7 seconds. We saw a decrease in variability of time to defibrillator pad placement. CONCLUSIONS: Implementation of a quality improvement initiative involving CPR transition choreography resulted in decreased interruptions in compressions and decreased variability of time to defibrillator pad placement.

Early and prehospital trauma deaths: Who might benefit from advanced resuscitative care?

BACKGROUND: Recent civilian and military data from the United States and the United Kingdom suggest that further reductions in mortality will require prehospital or preoperating room hemorrhage control and blood product resuscitation. The aims of this study were to examine the potential preventability of prehospital and early in-hospital fatalities, and to consider the geographical location of such incidents, to contextualize how the use of advanced resuscitative techniques could be operationalized. METHODS: Retrospective analysis of prehospital and early in-hospital trauma deaths from January to December 2017. Data were obtained from the Coroner/ME's Office. Each death was reviewed by a panel of two trauma surgeons and a forensic pathologist. Anatomical and physiological survivabilities were evaluated separately, and then combined, leading to a holistic assessment of preventability. Incident locations were mapped and analyzed using ArcGIS. RESULTS: Three hundred sixteen trauma deaths were identified. Two hundred thirty-one (73%) were deemed anatomically not survivable; 29 (9%) anatomically survivable, but only with hospital care; 43 (14%) anatomically survivable with advanced prehospital care; and 13 (4%) anatomically survivable with basic prehospital care. Physiologically, 114 (36%) of the patients had been dead for some time when found; 137 (43%) had no cardiorespiratory effort on arrival of Emergency Medical Services (EMS) at the scene; 24 (8%) had cardiorespiratory effort at the scene, but not on arrival at the emergency department; and 41 (13%) had cardiorespiratory effort on arrival at the emergency department, but died shortly after. Combining the assessments, 10 (3%) deaths were deemed probably not preventable, 38 (12%) possibly preventable, and the remaining 278 (85%) not preventable. CONCLUSION: Twelve percent of trauma deaths were potentially preventable and might be amenable to advanced resuscitative interventions. Operationalizing this type of care will be challenging and will require either prehospital doctors, or very highly trained paramedics, nurses, or physician assistants. LEVEL OF EVIDENCE: Epidemiological, level III.

Comparison of Ultrasound-Guided Vs Traditional Arterial Cannulation by Emergency Medicine Residents.

INTRODUCTION: We sought to determine whether ultrasound-guided arterial cannulation (USGAC) is more successful than traditional radial artery cannulation (AC) as performed by emergency medicine (EM) residents with standard ultrasound training. METHODS: We identified 60 patients age 18 years or older at a tertiary care, urban academic emergency department who required radial AC for either continuous blood pressure monitoring or frequent blood draws. Patients were randomized to receive radial AC via either USGAC or traditional AC. If there were three unsuccessful attempts, patients were crossed over to the alternative technique. All EM residents underwent standardized, general ultrasound training. RESULTS: The USGAC group required fewer attempts as compared to the traditional AC group (mean 1.3 and 2.0, respectively; p<0.001); 29 out of 30 (96%) successful radial arterial lines were placed using USGAC, whereas 14 out of 30 (47%) successful lines were placed using traditional AC (p<0.001). There was no significant difference in length of procedure or complication rate between the two groups. There was no difference in provider experience with respect to USGAC vs traditional AC. CONCLUSION: EM residents were more successful and had fewer cannulation attempts with USGAC when compared to traditional AC after standard, intern-level ultrasound training.

Advanced mobile prehospital nursing care for elderly people post-trauma: integrative review.

OBJECTIVE: to identify scientific evidences available on the literature on nursing interventions on advanced mobile prehospital care for elderly people post-trauma. METHOD: an integrative review of literature on the databases PubMed, CINAHL, and LILACS, from 2012 to 2017. RESULTS: a sample composed by 26 studies, grouped into six thematic categories: circulation with hemorrhage control (n=11); dysfunction, neurological state (n=7); airway with protection of the cervical spine (n=3); secondary evaluation (n=3); ventilation and breathing (n=1), and environment exposition/control (n=1). CONCLUSION: Despite having identified nursing interventions, there was no description of specific nursing interventions related to advanced mobile prehospital care for elderly people post-trauma.

Parallel Simulation Decision-Making Method for a Response to Unconventional Public Health Emergencies Based on the Scenario-Response Paradigm and Discrete Event System Theory.

Given the non-repeatability, complexity, and unpredictability of unconventional public health emergencies, building accurate models and making effective response decisions based only on traditional prediction-response decision-making methods are difficult. To solve this problem, under the scenario-response paradigm and theories on parallel emergency management and discrete event system (DES), the parallel simulation decision-making framework (PSDF), which includes the methods of abstract modeling, simulation operation, decision-making optimization, and parallel control, is proposed for unconventional public health emergency response processes. Furthermore, with the example of the severe acute respiratory syndrome (SARS) response process, the evolutionary scenarios that include infected patients and diagnostic processes are transformed into simulation processes. Then, the validity and operability of the DES-PSDF method proposed in this paper are verified by the results of a simulation experiment. The results demonstrated that, in the case of insufficient prior knowledge, effective parallel simulation models can be constructed and improved dynamically by multi-stage parallel controlling. Public health system bottlenecks and relevant effective response solutions can also be obtained by iterative simulation and optimizing decisions. To meet the urgent requirements of emergency response, the DES-PSDF method introduces a new response decision-making concept for unconventional public health emergencies.

The effect of Benson relaxation method on anxiety in the emergency care.

OBJECTIVE: To analyze clinical and sociodemographic properties of the patients as measured by the "Hospital Anxiety and Depression Scale-HADS" including the subscale regarding anxiety (HAD-A) in emergency department (ED) and to detect the effect of a session of Benson relaxation method (BRM) on high anxiety level. METHODS: Adult patients presented to the state hospital ED in seven days were recruited in this prospective study. Patients with high (≥8) scores were randomized to the treatment or control groups. They were asked to pursue BRM to alleviate anxiety. RESULTS: Six hundred thirty-four patients were recruited (mean age 44.1 and 52% were female). Patients with acute exacerbation or with psychiatric illness, with a systemic disease and higher acuity level had higher HAD-A scores (P < .05). BRM group had a mean score change higher than controls (7.2 ±â€Š2.9 vs 3.4 ±â€Š2.6, t test, P = .026). CONCLUSIONS: Patients who underwent BRM had larger decreases in HAD-A scores than others.
