An emergency physician (EP) is often the first provider to evaluate, resuscitate, and manage a critically ill patient. Over the past two decades, the annual hours of critical care delivered in emergency departments across the United States has dramatically increased. During the period from 2006 to 2014, the extent of critical care provided in the emergency department (ED) to critically ill patients increased approximately 80%. During the same time period, the number of intubated patients cared for in the ED increased by approximately 16%. In addition to seeing more critically ill patients, EPs are often tasked with providing critical care long beyond the initial resuscitation period. Prolonged ED boarding times for critically ill patients is associated with increased duration of mechanical ventilation, increased intensive care unit (ICU) length of stay, increased hospital length of stay, increased medication-related adverse events, and increased in-hospital, 30-day, and 90-day mortality. As a result, it is imperative for the EP to be knowledgeable about recent developments in resuscitation and critical care medicine, so that the critically ill ED patient care receive current evidence-based care. These articles have been selected based on the authors review of key critical care, resuscitation, emergency medicine, and medicine journals and their opinion of the importance of study findings as it pertains to the care of the critically ill ED patient. Topics covered in this article include cardiac arrest, post-cardiac arrest care, rapid sequence intubation, mechanical ventilation, fluid resuscitation, cardiogenic shock, transfusions, and sepsis.

Angioedema is a well-recognized and potentially lethal complication of angiotensin-converting enzyme inhibitor (ACEi) therapy. In ACEi-induced angioedema, bradykinin accumulates due to a decrease in its metabolism by ACE, the enzyme that is primarily responsible for this function. The action of bradykinin at bradykinin type 2 receptors leads to increased vascular permeability and the accumulation of fluid in the subcutaneous and submucosal space. Patients with ACEi-induced angioedema are at risk for airway compromise because of the tendency for the face, lips, tongue, and airway structures to be affected. The emergency physician should focus on airway evaluation and management when treating patients with ACEi-induced angioedema.

Given the dramatic increase in critically ill patients who present to the emergency department for care, along with the persistence of boarding of critically ill patients, it is imperative for the emergency physician to be knowledgeable about recent developments in resuscitation and critical care medicine. This review summarizes important articles published in 2020 that pertain to the resuscitation and care of select critically ill patients. These articles have been selected based on the authors annual review of key critical care, emergency medicine and medicine journals and their opinion of the importance of study findings as it pertains to the care of critically ill ED patients. Several key findings from the studies discussed in this paper include the administration of dexamethasone to patients with COVID-19 infection who require mechanical ventilation or supplemental oxygen, the use of lower levels of positive end-expiratory pressure for patients without acute respiratory distress syndrome, and early initiation of extracorporeal membrane oxygenation for out-of-hospital cardiac arrest patients with refractory ventricular fibrillation if resources are available. Furthermore, the emergency physician should not administer tranexamic acid to patients with acute gastrointestinal bleeding or administer the combination of vitamin C, thiamine, and hydrocortisone for patients with septic shock. Finally, the emergency physician should titrate vasopressor medications to more closely match a patient's chronic perfusion pressure rather than target a mean arterial blood pressure of 65 mmHg for all critically ill patients.

Decompensation on the medical floor is associated with increased in-hospital mortality.Our aim was to determine the accuracy of the National Early Warning Score (NEWS) in predicting early, unplanned escalation of care in patients admitted to the hospital from the emergency department (ED) compared to the Shock Index (SI) and the quick Sepsis-Related Organ Failure Assessment (qSOFA) score.We conducted a retrospective cohort study of patients admitted directly from the ED to monitored or unmonitored beds (November 9, 2015 to April 30, 2018) in 3 hospitals. Interhospital transfers were excluded. Patient data, vital status, and bed assignment were extracted from the electronic medical record. Scores were calculated using the last set of vital signs prior to leaving the ED. Primary endpoint was in-hospital death or placement in an intermediate or intensive care unit within 24 h of admission from the ED. Scores were compared using the area under the receiver operating curve (AUROC).Of 46,018 ED admissions during the study window, 39,491 (85.8%) had complete data, of which 3.7% underwent escalation in level of care within 24 h of admission. NEWS outperformed (AUROC 0.69; 95% confidence interval [CI] 0.68-0.69) qSOFA (AUROC 0.63; 95% CI 0.62-0.63; p 0.001) and SI (AUROC 0.60; 95% CI 0.60-0.61; p 0.001) at predicting unplanned escalations or death at 24 h.This multicenter study found NEWS was superior to the qSOFA score and SI in predicting early, unplanned escalation of care for ED patients admitted to a general medical-surgical floor.

The emergency department resuscitation of the critically ill geriatric patient is challenging and can be fraught with peril. The anatomic and physiologic changes that occur with aging can significantly influence the recognition of critical illness and the logistics of resuscitation itself. This article discusses the relevant physiologic changes with aging, the effect of these changes on clinical manifestations of critical illness in older adults, and the core principles of resuscitation in this population, with specific attention to sepsis and trauma care. In addition, end-of-life care is also discussed.

An emergency physician (EP) is often the first health care provider to evaluate, resuscitate, and manage a critically ill patient. Between 2001 and 2009, the annual hours of critical care delivered in emergency departments (EDs) across the United States increased >200% [1]! This trend has persisted since then. In addition to seeing more critically ill patients, EPs are often tasked with providing critical care long beyond the initial resuscitation period. In fact, >33% of critically ill patients who are brought to an ED remain there for >6 h [1]. Longer ED boarding times for critically ill patients have been associated with a negative impact on inpatient morbidity and mortality [2]. During these crucial early hours of illness, detrimental pathophysiologic processes begin to take hold. It is during these early hours of illness where lives can be saved, or lost. Therefore, it is important for the EP to be knowledgeable about recent developments in critical care medicine. This review summarizes important articles published in 2017 pertaining to the resuscitation and care of select critically ill patients in the ED. We chose these articles based on our opinion of the importance of the study findings and their application to clinical care. The following topics are covered: sepsis, vasolidatory shock, cardiac arrest, post-cardiac arrest care, post-intubation sedation, and pulmonary embolism.

Background Angioedema is a complication that has been reported in up to 1.0% of individuals taking angiotensin-converting enzyme inhibitors (ACE-Is). Importantly, the onset of angioedema can occur anywhere from hours to several years after initiation of therapy with ACE-Is. Although most cases of ACE-I–induced angioedema (ACE-I-AE) are self-limiting, a major clinical concern is development of airway compromise, which can potentially require emergent airway management. The underlying pathophysiology of ACE-I-AE is incompletely understood, but is considered to be due in large part to excess bradykinin. Numerous medications have been proposed for the treatment of ACE-I-AE. This article is an update to the 2011 Clinical Practice Committee (CPC) statement from the American Academy of Emergency Medicine. Methods A literature search in PubMed was performed with search terms angioedema and ACE inhibitors from August 1, 2012 to May 13, 2019. Following CPC guidelines, articles written in English were identified and then underwent a structured review for evaluation. Results The search parameters resulted in 323 articles. The abstracts of these articles were assessed independently by the reviewers, who determined there were 63 articles that were specific to ACE-I-AE, of which 46 were deemed appropriate for grading in the final focused review. Conclusions The primary focus for the treatment of ACE-I-AE is airway management. In the absence of high-quality evidence, no specific medication therapy is recommended for its treatment. If, however, the treating physician feels the patient's presentation is more typical of an acute allergic reaction or anaphylaxis, it may be appropriate to treat for those conditions. Any patient with suspected ACE-I-AE should immediately discontinue that medication.

Background In 2010, the U.S. Food and Drug Administration (FDA) approved dabigatran as the first non-warfarin oral anticoagulant for use in the United States. At the time of FDA approval, there was no antidote or effective treatment for dabigatran-induced hemorrhage. In 2015, the FDA approved idarucizumab for the treatment of dabigatran-induced hemorrhage. The purpose of this clinical practice statement is to evaluate the role of select reversal agents in the management of patients with dabigatran-associated bleeding. Methods A PubMed literature review was completed to identify studies that investigated the role of reversal agents in the management of emergency department patients with dabigatran-associated hemorrhage. Articles included were those published in the English language between January 2010 and January 2017, enrolled human subjects, and limited to the following types: randomized controlled trials, prospective trials, meta-analyses, and retrospective cohort studies. Review articles, case series, and case reports were not included in this review. All selected articles then underwent a structured review by the authors. Results Six hundred fifty-two articles were identified in the search. After use of predetermined inclusion and exclusion criteria, six articles were selected for structured review. Conclusion The clinical efficacy of activated prothrombin complex concentrates, idarucizumab, and recombinant factor VIIa remains unclear until further research is performed. Activated prothrombin complex concentrates, idarucizumab, and recombinant factor VIIa may be considered in patients with serious bleeding from dabigatran, after careful consideration of possible benefits and risks.

Background Current guidelines for the management of patients with severe sepsis and septic shock recommend crystalloids as the initial fluid solution of choice in the resuscitation of these patients. In recent years, there have been numerous studies published on the type of fluid used in the resuscitation of patients with sepsis. The primary goal of this article is to determine the preferred intravenous fluid for the resuscitation of patients with severe sepsis and septic shock. Methods A MEDLINE literature review was completed to identify studies that investigated the type of resuscitation fluid in the management of patients with severe sepsis and septic shock. Articles included were those published in English between 2011 and 2016, enrolled human subjects, and limited to the following types: randomized controlled trial, prospective observational trial, retrospective cohort trial, and meta-analyses. All selected articles then underwent a structured review by the authors. Results Nine thousand sixty-two articles were identified in the search. After use of predetermined criteria, 17 articles were selected for review. Eleven of these were original investigations and six were meta-analyses and systemic reviews. Conclusion Crystalloids are the preferred solution for the resuscitation of emergency department patients with severe sepsis and septic shock. Balanced crystalloids may improve patient-centered outcomes and should be considered as an alternative to normal saline, if available. There is strong evidence that suggests semi-synthetic colloids decrease survival and should be avoided. The role of albumin in the resuscitation of patients with severe sepsis and sepsis is uncertain.

High-quality chest compressions are a critical component of the resuscitation of patients in cardiopulmonary arrest. Point-of-care ultrasound (POCUS) is used frequently during emergency department (ED) resuscitations, but there has been limited research assessing its benefits and harms during the delivery of cardiopulmonary resuscitation (CPR). We hypothesized that use of POCUS during cardiac arrest resuscitation adversely affects high-quality CPR by lengthening the duration of pulse checks beyond the current cardiopulmonary resuscitation guidelines recommendation of 10s.We conducted a prospective cohort study of adults in cardiac arrest treated in an urban ED between August 2015 and September 2016. Resuscitations were recorded using video equipment in designated resuscitation rooms, and the use of POCUS was documented and timed. A linear mixed-effects model was used to estimate the effect of POCUS on pulse check duration.Twenty-three patients were enrolled in our study. The mean duration of pulse checks with POCUS was 21.0s (95% CI, 18-24) compared with 13.0s (95% CI, 12-15) for those without POCUS. POCUS increased the duration of pulse checks and CPR interruption by 8.4s (95% CI, 6.7-10.0 [p0.0001]). Age, body mass index (BMI), and procedures did not significantly affect the duration of pulse checks.The use of POCUS during cardiac arrest resuscitation was associated with significantly increased duration of pulse checks, nearly doubling the 10-s maximum duration recommended in current guidelines. It is important for acute care providers to pay close attention to the duration of interruptions in the delivery of chest compressions when using POCUS during cardiac arrest resuscitation.

An emergency physician (EP) is often the first health care provider to evaluate, resuscitate, and manage a critically ill patient. Between 2001 and 2009, the annual hours of critical care delivered in emergency departments (EDs) across the United States increased >200%! (Herring et al., 2013). This trend has persisted since then. In addition to seeing more critically ill patients, EPs are often tasked with providing critical care long beyond the initial resuscitation period. In fact, >33% of critically ill patients who are brought to an ED remain there for >6h (Herring et al., 2013). During these crucial early hours of illness, detrimental pathophysiologic processes begin to take hold. During this time, lives can be saved or lost. Therefore, it is important for the EP to be knowledgeable about recent developments in critical care medicine. This review summarizes important articles published in 2016 pertaining to the care of select critically ill patients in the ED. The following topics are covered: intracerebral hemorrhage, traumatic brain injury, anti-arrhythmic therapy in cardiac arrest, therapeutic hypothermia, mechanical ventilation, sepsis, and septic shock.

Background Current international guidelines for the treatment of patients with severe sepsis and septic shock recommend that patients receive targeted care to various physiologic endpoints, thereby optimizing tissue perfusion and oxygenation. These recommendations are primarily derived from a protocol published >15 years ago, which was viewed by many as complex and was therefore not widely adopted. Instead, many emergency physicians focused on the administration of early antibiotics, source control, aggressive fluid resuscitation, vasoactive medications as needed to maintain mean arterial blood pressure, and careful monitoring of these patients. The primary goal of this literature search was to determine if there is a mortality benefit to the early goal-directed protocol recommended by current international sepsis guidelines compared to current usual care. Methods A MEDLINE literature search was performed for studies published between January 1, 2010 and December 31, 2015. Studies were limited to the English language, human randomized controlled trials, meta-analyses, prospective trials, and retrospective cohort trials that met specific keyword search criteria. Case reports, case series, and review articles were excluded. All selected articles then underwent a structured review by the authors. Results Seven thousand four hundred twenty studies were initially screened; after the final application of inclusion and exclusion criteria, 10 studies were formally analyzed. Each study then underwent a rigorous review and evaluation from which a formal recommendation was made. Conclusion There is no difference in mortality between current usual care and the goal-directed approach recommended by current international guidelines for patients with severe sepsis and septic shock.

Planning for clerkships in emergency medicine (EM) can be stressful, prolonged, and challenging. Therefore, medical students should start planning for them early. In this article, we offer guidance regarding several issues pertinent to the EM clerkship, such as the best time to schedule one (or more) during medical school, the most appropriate institution or program to schedule it, the process of selecting and applying for the clerkship, and the number of EM clerkships to consider. We will explain why an EM clerkship should be scheduled between June and October and the reason that 2 EM clerkships at different sites are sufficient for the majority of students. Additionally, we emphasize that clerkships in emergency departments associated with EM residency programs or with reputations for outstanding student teaching tend to be most beneficial. Above all, students interested in EM should attempt to leave a great impression after completing their clerkships by providing stellar patient care, demonstrating enthusiasm at all times, and maintaining professionalism. In turn, they will gain knowledge and clinical experiences that should prove valuable in their future.

An emergency physician (EP) is often the first health care provider to evaluate, resuscitate, and manage a critically ill patient. In recent years, the annual hours of critical care delivered in emergency departments (EDs) across the United States increased more than 200% (Herring et al., 2013). In addition to seeing more critically ill patients, EPs are often tasked with providing critical care long beyond the initial resuscitation period. In fact, more than 50% of ED patients that require admission to the intensive care unit (ICU) remain in the ED for more than 6 h (Rose et al., 2016). Longer ED boarding times for critically ill patients is associated with a negative impact on inpatient morbidity and mortality (Mathews et al., 2018). It is during these early hours of critical illness, while the patient is in the ED, where lives can be saved or lost. Therefore, it is important for the EP to be knowledgeable about recent developments in critical care medicine. This review summarizes important articles published in 2018 pertaining to the resuscitation and care of select critically ill patients. We chose these articles based on our opinion of the importance of the study findings and their application to clinical care in the ED. The following topics are covered: cardiac arrest, post-arrest care, septic shock, rapid sequence intubation, mechanical ventilation, fluid resuscitation, and metabolic acidosis.

There are currently 5 combined residencies in emergency medicine (EM), namely EM/pediatrics, EM/internal medicine, EM/internal medicine/critical care, EM/family medicine and EM/anesthesiology. These combined programs vary from 5–6 years in length. Like categorical programs, the decision to enter a 5- or 6-year program should be an informed and comprehensive decision. We describe the history and current status of the combined EM programs, discuss the process of applying to a combined EM program, describe the life of combined EM residents, and explore common career opportunities available to combined EM program graduates.

Noninvasive ventilation (NIV) improves oxygenation and ventilation, prevents endotracheal intubation, and decreases the mortality rate in select patients with acute respiratory failure. Although NIV is used commonly for acute exacerbations of chronic obstructive pulmonary disease and acute cardiogenic pulmonary edema, there are emerging indications for its use in the emergency department. Emergency physicians must be knowledgeable regarding the indications and contraindications for NIV in emergency department patients with acute respiratory failure as well as the means of initiating it and monitoring patients who are receiving it.

Patients with acute decompensated heart failure are usually critically ill and require immediate treatment. However, most are not volume overloaded. Emergency department (ED) management is based on rapid initiation of noninvasive positive-pressure ventilation and aggressive titration of nitrates. Afterload reduction with an angiotensin-converting enzyme inhibitor can be considered. A diuretic should not be administered before optimal preload and afterload reduction has been achieved. Short-term inotropic therapy can be considered in select patients with cardiogenic shock and acute decompensated heart failure (ADHF) who fail to respond to standard therapy.

Since its original description in 1832, fluid resuscitation has become the cornerstone of early and aggressive treatment of severe sepsis and septic shock. However, questions remain about optimal fluid composition, dose, and rate of administration for critically ill patients. This article reviews pertinent physiology of the circulatory system, pathogenesis of septic shock, and phases of sepsis resuscitation, and then focuses on the type, rate, and amount of fluid administration for severe sepsis and septic shock, so providers can choose the right fluid, for the right patient, at the right time.

Purpose Emergency department (ED) patients are at high risk for the acute respiratory distress syndrome (ARDS). Settings only 1 mL/kg above recommended tidal volumes confers harm for these patients. The purpose of this study was to determine whether ED physicians routinely initiate mechanical ventilation with low tidal volumes in patients at risk for ARDS. Materials and Methods We retrospectively reviewed the charts of all adult patients who were intubated in an urban, academic ED. The charts were analyzed to identify patients in whom ARDS developed within 48 hours after ED admission. Patients were eligible for inclusion if they had bilateral infiltrates on imaging, had a Pa o 2 /F io 2 ratio less than 300 mm Hg and did not have heart failure contributing to their presentation. The tidal volumes set in the ED were then compared with the recommended tidal volume of 6 mL/kg of predicted body weight. Results The initial tidal volumes set in the ED were higher than recommended by an average of 80 mL (95% confidence interval, 60-110, P Conclusions In an academic, tertiary hospital, newly intubated ED patients in whom ARDS developed within 48 hours after intubation were ventilated with tidal volumes that exceeded recommendations by an average of 1.5 mL/kg.

Background Angiotensin-converting-enzyme inhibitors (ACEI) are one of the most prescribed medications worldwide. Angioedema is a well-recognized adverse effect of this class of medications, with a reported incidence of ACEI angioedema of up to 1.0%. Of importance to note, ACEI angioedema is a class effect and is not dose dependent. The primary goal of this literature search was to determine the appropriate Emergency Department management of patients with ACEI angioedema. Methods A MEDLINE literature search from January 1990 to August 2012 and limited to human studies written in English for articles with keywords of ACEI angioedema. Guideline statements and non-systematic reviews were excluded. Studies identified then underwent a structured review from which results could be evaluated. Results Five hundred sixty-two papers on ACEI angioedema were screened and 27 appropriate articles were rigorously reviewed in detail and recommendations given. Conclusion The literature search did not support any specific treatment protocol with a high level of evidence due to the limited—and limitations of the—available studies.

Background Emergency Department (ED) crowding and inpatient boarding lead to lengthy wait times for patients, which may cause them to choose to leave without being seen. A new initiative to improve communication with patients is to provide an estimated wait time with a "time tracker" display, but it is unclear whether ED patients would welcome this. Objective To estimate the proportion of ED patients who would favor a time tracker display. Methods This survey-based study was conducted from March to July 2010 at an urban academic center. After being triaged, patients were asked to answer a multiple-choice questionnaire, asking their preference toward a time tracker display. Results Of the 375 patients who were approached, 340 (91%) participated. Two hundred fourteen of them (63%) preferred an ED with a time tracker, 53 (16%) were unsure, and 73 (21%) did not prefer an ED with a time tracker. Patients with low-acuity conditions (Emergency Severity Index [ESI] 4 or 5) were 1.2 times more likely (95% confidence interval 1.0–1.4) to favor a time tracker than those with higher acuity (ESI 3). Preference was not related to race, age, insurance status, or employment. Conclusions The majority of patients in our study preferred an ED with a time tracker display (63% for vs. 21% against). Support for a time tracker was higher among patients triaged with lower ESI levels (4 or 5). A time tracker is viewed positively by many patients and may be a beneficial addition in the ED waiting room.

Background Severe sepsis and septic shock remain significant public health concerns. Appropriate emergency department management includes early recognition, hemodynamic resuscitation, source control, and prompt antibiotic administration. Current international guidelines strongly recommend administration of early and appropriate antibiotics for patients with severe sepsis and septic shock. Interestingly, a recent Cochrane Review found insufficient evidence to provide a similar recommendation on antibiotic administration. The goal of this literature search was to systematically review the available literature on early and appropriate antimicrobial therapy and provide emergency physicians an evidence-based approach to antibiotic therapy for septic patients. Methods Four PubMed searches were completed to identify abstracts of relevant interest. We limited studies to those completed in adult humans that were composed in English between 2005 and 2015. Included studies were randomized controlled trials, meta-analyses, prospective trials, and retrospective cohort studies. These studies were identified by a rigorous search methodology. No review articles, case series, or case reports were included. Predefined criteria were used to evaluate the quality and appropriateness of selected articles as part of a structured review. Results A total of 1552 abstracts were evaluated for inclusion. After the review of these studies, 14 were included for formal review. The authors then systematically evaluated each study, which formed the basis for this clinical statement. Conclusions Patients with severe sepsis and septic shock should receive early and appropriate antibiotics in the emergency department. Patients with septic shock who received appropriate antimicrobial therapy within 1 h of recognition had the greatest benefit in mortality.

Background Acute cerebrovascular accident (CVA) is a devastating cause of patient morbidity and mortality. Up to 10% of acute CVAs in young patients are caused by dissection of the vertebral or carotid artery. Wallenberg syndrome results from a CVA in the vertebral or posterior inferior artery of the cerebellum and manifests as various degrees of cerebellar dysfunction. The administration of a thrombolytic medication has been recommended in the treatment of patients with stroke caused by cervical artery dissection. Surprisingly, there is scant literature on the use of this medication in the treatment of this condition. Case Report We describe a 42-year-old man with the sudden onset of headache, left-sided neck pain, vomiting, nystagmus, and ataxia 1 h after completing a weightlifting routine. Computed tomography angiography revealed a grade IV left vertebral artery injury with a dissection flap extending distally and resulting in complete occlusion. Subsequent magnetic resonance imaging and angiography demonstrated acute left cerebellar and lateral medullary infarcts, consistent with Wallenberg syndrome. The patient was treated with tissue plasminogen activator, which failed to resolve his symptoms. Why Should an Emergency Physician Be Aware of This? Emergency physicians frequently manage patients with acute CVAs. For select patients, the administration of tissue plasminogen activator can improve outcomes. However, the risk of major hemorrhage with this medication is significant. Cervical artery dissection is an important cause of acute stroke in young patients and is often missed on initial presentation. It is imperative for the emergency physician to consider acute cervical artery dissection as a cause of stroke and to be knowledgeable regarding the efficacy of thrombolytic medications for this condition.

Objectives The primary objective was to determine if providing patients with a complete course of antibiotics for select conditions would decrease the rate of return to the emergency department (ED) within 7 days of the initial visit. Methods In an urban, academic medical center, we compared patients who received medications at discharge (To-Go medications) with patients who received standard care (a prescription at discharge). Emergency department patients were included if they were older than 18 years; had a discharge diagnosis International Classification of Diseases, Ninth Revision , code for urinary tract infection, pyelonephritis, cellulitis, or dental infection; and presented initially between January and December 2010. Candidates had limited health insurance or were discharged when nearby pharmacies were closed. Return visits were included if the condition was related to the initial diagnosis. Wound checks and scheduled revisits were excluded. Medications dispensed were penicillin, clindamycin, sulfamethoxazole-trimethoprim, and nitrofurantoin. Results A total of 4257 individuals were seen in initial ED visits for the included conditions. Comparing the 243 individuals given medications with the 4014 who were not given medications, the To-Go medications group was less likely to return than the comparison group (2.5% vs 5.9%; P = .026). The cellulitis subgroup also showed a significant reduction in return visits (1.6% vs 6.9%; P = .024). Three hundred eighteen courses of medication were given to the 243 individuals for a total cost of $1123. Conclusions For a 1-year expense of $1123, we demonstrated a 50% reduction in ED return visits for patients who were given a free, complete course of antibiotics at discharge for select conditions.

Care of the patient with return of spontaneous circulation following sudden cardiac death is complex and challenging. A systematic and comprehensive approach can increase the chances of meaningful recovery of the postarrest patient. This article focuses on a systematic approach to the postarrest patient, which includes optimizing oxygenation and ventilation, maintaining adequate perfusion pressure, monitoring oxygen delivery, initiating and maintaining therapeutic hypothermia, and identifying patients appropriate for emergent cardiac catheterization. Using this approach, providers treating the postarrest patient can maximize the chance that a patient walks out of the hospital neurologically intact.

Caring in the emergency department for the patient with return of spontaneous circulation after cardiac arrest is challenging. A coordinated and systematic approach to post-cardiac arrest care can improve the mortality and the chance of meaningful neurologic recovery. By achieving appropriate targets for oxygenation, ventilation, and hemodynamic parameters, along with initiating therapeutic hypothermia and arranging early percutaneous coronary intervention, the emergency physician can have the most significant impact on patients who have just been revived from death.

Background: Emergency physicians perform tracheal intubation and initiate mechanical ventilation for critically ill patients on a daily basis. With the current national challenges of intensive care unit bed availability, intubated patients now often remain in the emergency department (ED) for exceedingly long periods of time. As a result, care of the intubated patient falls to the emergency physician (EP). Given the potential for significant morbidity and mortality, it is crucial for the EP to possess the most current, up-to-date information pertaining to the care of intubated patients. Discussion: This article discusses critical aspects in the ED management of intubated and mechanically ventilated patients. Specifically, emphasis is placed on providing adequate sedation and analgesia, limiting the use of neuromuscular blocking agents, correctly setting and adjusting the mechanical ventilator, utilizing appropriate monitoring modalities, and providing key supportive measures. Despite these measures, inevitably, some patients deteriorate while receiving mechanical ventilation. The article concludes with a discussion outlining a step-wise approach to evaluating the intubated patient who develops respiratory distress or circulatory compromise. With this information, the EP can more effectively care for ventilated patients while minimizing morbidity, and ultimately, improving outcome. Conclusion: Essential components of the care of intubated ED patients includes administering adequate sedative and analgesic medications, using lung-protective ventilator settings with attention to minimizing ventilator-induced lung injury, elevating the head of the bed in the absence of contraindications, early placement of an orogastric tube, and providing prophylaxis for stress-related mucosal injury and deep venous thrombosis when indicated.

Many critically ill patients are remaining in the emergency department for extended periods of time, and delays in diagnosis and/or therapy may increase patient morbidity and mortality. All emergency physicians use monitoring modalities in critically ill patients to detect early cardiovascular compromise and impaired oxygen delivery before disastrous collapse occurs. The authors hope the discussion in this article regarding the monitoring of oxygenation, ventilation, arterial perfusion pressure, intravascular volume, markers of tissue hypoxia, and cardiac output will help the EP provide optimal care for this complicated patient population.

Background Urine cultures are not always performed for female Emergency Department (ED) patients with uncomplicated urinary tract infection (UTI). Accordingly, hospital, and even ED-specific, antibiograms might be skewed toward elderly patients with many comorbidities and relatively high rates of antimicrobial resistance, and thus do not accurately reflect otherwise healthy women. Our ED antibiogram indicates Escherichia coli resistance rates for ciprofloxacin, levofloxacin, and trimethoprim-sulfamethoxazole (TMP-SMX) of 42%, 26%, and 33%, respectively. Objectives This study aims to compare resistance rates of urinary E. coli from otherwise healthy women with uncomplicated UTI and pyelonephritis in the ED to rates in our ED antibiogram. Methods Females > 18 years old with acute onset of urinary frequency, urgency, or dysuria with pyuria identified on urinalysis (white blood cell count > 10/high-power field) were prospectively enrolled in the ED of an urban, academic medical center. Exclusion criteria indicating a complicated UTI were consistent with Infectious Diseases Society of America guidelines. Susceptibility patterns of E. coli to ciprofloxacin, levofloxacin, and TMP-SMX in the study group were compared to our ED antibiogram. Results Forty-five patients grew E. coli. Pyelonephritis was suspected in nine (20%) subjects. Compared with the ED antibiogram, significantly lower rates of resistance to ciprofloxacin (2% vs. 42%, p p p = 0.016) were observed. Six patients grew non- E. coli uropathogens. All were susceptible to both levofloxacin and TMP-SMX. Conclusions ED antibiograms may overestimate resistance rates for uropathogens causing uncomplicated UTIs. In cases where nitrofurantoin cannot be used, fluoroquinolones and possibly TMP-SMX may remain viable options for treatment of uncomplicated UTI and pyelonephritis in women.

Most adults in the United States will experience an episode of back pain at some point during their lifetime. Most will present to their primary care physician for evaluation and treatment. Many patients have non-life-threatening etiologies and recover within 4 to 6 weeks. A small percentage, however, have back pain due to a potentially life-threatening emergency. AD,rupturing AAA, SEM, cauda equina syndrome, vertebral osteomyelitis,and SEA are just some of the medical emergencies that can present with back pain. Clinical suspicion for these diagnoses begins with a thorough history and physical examination. It is imperative that the office-based physician search for and accurately identify any red flag within the history or physical examination. Appropriate laboratory studies and diagnostic imaging are obtained based on the suspected etiology.
