  • Toolkit: Emergency Department Management of Sepsis in Adults and Young People Over 12 Years- 2016
    Toolkit: Emergency Department management of Sepsis in adults and young people over 12 years- 2016 This clinical toolkit has been developed in partnership with the Royal College of Emergency Medicine and in full communication with the National Institute for Health and Care Excellence (NICE). It is designed to provide operational solutions to the complexities challenging the reliable identification and management of sepsis which are compatible with the 2016 NICE Clinical Guideline on Sepsis (NG51), and complements clinical toolkits designed for other clinical areas. Produced for the UK Sepsis Trust by: Dr Tim Nutbeam Dr Ron Daniels Dr Jeff Keep UKST EM TOOLKIT 2016 1 Staff working in Emergency Departments (ED) should be familiar with the significant morbidity and mortality associated with sepsis and possess the knowledge and skills to recognize it early and initiate resuscitation and treatment. The ED provides a key role in identifying patients at risk of sepsis, followed by risk stratification for sepsis and septic shock, initiating resuscitation and treatment, and ensuring the correct onward management of patients identified with sepsis. EDs are vital to the success of collaborative care pathways for the seamless management of patients with sepsis from the prehospital environment, through the ED, and to admission in either a ward bed or the Critical Care Unit. Sepsis responds well to early treatment and, if required, rapid escalation of therapy. 1 Background The UK mortality rate for patients admitted with sepsis is 30%1 - approximately 5 times higher than for ST elevation myocardial infarction and stroke - and is responsible for approximately 44,000 deaths and 150,000 hospital admissions in the United Kingdom (UK) per year2.

  • Hemorrhagic Shock: the “Physiology Approach”
    Review Article Hemorrhagic shock: The “physiology approach” Fabrizio Giuseppe Bonanno Trauma Directorate, Chris Hani Baragwanath Hospital, Johannesburg, South Africa ABSTRACT A shift of approach from ‘clinics trying to fit physiology’ to the one of ‘physiology to clinics’, with interpretation of the clinical phenomena from their physiological bases to the tip of the clinical iceberg, and a management exclusively based on modulation of physiology, is finally surging as the safest and most efficacious philosophy in hemorrhagic shock. ATLS® classification and recommendations on hemorrhagic shock are not helpful because antiphysiological and potentially misleading. Hemorrhagic shock needs to be reclassified in the direction of usefulness and timing of intervention: in particular its assessment and management need to be tailored to physiology. Key Words: Classification, hemorrhagic shock, management INTRODUCTION management of a scenario or of a problem [Table 1]. ATLS® classification of hemorrhagic shock (HS)[1] is not sensitive It has always been puzzling trying to understand and accept the and specific enough to help decision-making in reference to rationale and benefits of the ATLS classification[1] especially after the timing of management, being based only on the amount having replaced Holcroft more sensible classification,[2] as for the of blood loss that may or may not be rightly estimated, and difficulty of practical implementation with reference to timing and it is unhelpful and difficult to apply too.[9] The previous optimal management.

  • The Evolving Science of Trauma Resuscitation
    The Evolving Science of Trauma Resuscitation a b Tim Harris, BM BS, BMed Sci, Dip O&G, DipIMC, FFAEM , Ross Davenport, PhD , c d,e, Matthew Mak, BSc, MSc, MBBS, FRCEM, FHEA , Karim Brohi, FRCS, FRCA * KEYWORDS Trauma resuscitation Hypovolemia Trauma-induced coagulopathy Viscoelastic hemostatic assays Endothelial damage Hemostasis KEY POINTS Future research should inform clinicians on the role of permissive hypovolemia, for how long this should be maintained, and how/if this should be applied to patients with trau- matic brain injury. Our understanding of trauma-induced coagulopathy (TIC) is evolving and may see tar- geted blood component therapy incorporated early in trauma shock resuscitation. The role of viscoelastic hemostatic assays in assessing TIC and directing blood compo- nent resuscitation requires further study. There is increasing understanding of endothelial damage as a driver of TIC, raising the possibility of targeting repair to improve hemostasis and reduce organ failure. More work is required to identify the most appropriate goals for posthemostasis resusci- tation balancing the risks of fluid overload and underresuscitation. INTRODUCTION The 2 leading causes of death after trauma are blood loss and neurologic injury, which account for more than three-quarters of injury related mortality.1 Fifty percent of early deaths (<24 hours from injury) are due to hemorrhage, with hemorrhagic shock an important driver for postresuscitation organ failure and late mortality.1–3 There has been a considerable improvement in

  • Tintinalli – Approach to Nontraumatic Shock
    Tintinalli's Emergency Medicine: A Comprehensive Study Guide, 9e Chapter 12: Approach to Nontraumatic Shock Bret A. Nicks; John P. Gaillard FIGURE 12-1. EPIDEMIOLOGY Using a systolic blood pressure <90 mm Hg as criteria, 0.4% to 1.3% of patients presenting to EDs are in shock.1 Mortality depends on the inciting event. Septic shock has an estimated hospital mortality of 26%.2 Cardiogenic shock has an estimated hospital mortality of 39% to 48%.3,4 Neurogenic shock occurs in <20% of spinal cord injuries (cervical, 19.3%; thoracic, 7%; lumbar, 3%).5 The definition of and treatment approach to shock continue to evolve, but the initial approach to a patient in shock follows similar principles, regardless of the inciting factors or cause. Patients present to the ED in varying stages of critical illness and shock. These stages are confounded by age, comorbidities, and delays in presentation. A focus on early recognition, rapid diagnosis, and empiric resuscitation is essential. Therapy and patient stabilization may need to occur simultaneously with evaluation. PATHOPHYSIOLOGY Shock is a state of circulatory insuïiciency that creates an imbalance between tissue oxygen supply (delivery) and demand (consumption), resulting in end-organ dysfunction. Reduction in eïective perfusion may be due to a local or global delivery deficiency or utilization deficiency with suboptimal substrate at the cellular or subcellular level.6-8 The mechanisms that can result in shock are frequently divided into four categories: (1) hypovolemic, (2) distributive, (3) cardiogenic, and (4) obstructive. CATEGORIES OF SHOCK The four categories of shock can be described in terms of their respective physiologic changes and common causes, recognizing that a single etiology may manifest the clinical findings of more than one shock type (Table 12-1).9,10 Hypovolemic shock occurs when decreased intravascular fluid or decreased blood volume causes decreased preload, stroke volume, and cardiac output (CO).

Methods—Pre-planned secondary analysis of a large, multicenter ED-based randomized controlled trial of early sepsis resuscitation. All subjects were treated with a quantitative resuscitation protocol in the ED targeting 3 physiological variables: central venous pressure, mean arterial pressure and either central venous oxygen saturation or lactate clearance. The study protocol was continued until all endpoints were achieved or a maximum of 6 hours. Outcomes data of patients who were enrolled with a lactate ≥ 4 mmol/L and normotension (cryptic shock) were compared to those enrolled with sustained hypotension after fluid challenge (overt shock).

Abstract Trauma is a leading cause of death worldwide, and almost 30% of trauma deaths are due to blood loss. A number of concerns have been raised regarding the advisability of the classic principles of aggressive crystalloid resuscitation in traumatic hemorrhagic shock. Some recent studies have shown that early volume restoration in certain types of trauma before definite hemostasis may result in accelerated blood loss, hypothermia, and dilutional coagulopathy. This review discusses the advances and changes in protocols in fluid resuscitation and blood transfusion for treatment of traumatic hemorrhage shock. The concept of low volume fluid resuscitation also known as permissive hypotension avoids the adverse effects of early aggressive resuscitation while maintaining a level of tissue perfusion that although lower than normal, is adequate for short periods. Permissive hypotension is part of the damage control resuscitation strategy, which targets the conditions that exacerbate hemorrhage.
