Management of bleeding and coagulopathy following major trauma: an updated European guideline.

INTRODUCTION: Evidence-based recommendations are needed to guide the acute management of the bleeding trauma patient. When these recommendations are implemented patient outcomes may be improved. METHODS: The multidisciplinary Task Force for Advanced Bleeding Care in Trauma was formed in 2005 with the aim of developing a guideline for the management of bleeding following severe injury. This document represents an updated version of the guideline published by the group in 2007 and updated in 2010. Recommendations were formulated using a nominal group process, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) hierarchy of evidence and based on a systematic review of published literature. RESULTS: Key changes encompassed in this version of the guideline include new recommendations on the appropriate use of vasopressors and inotropic agents, and reflect an awareness of the growing number of patients in the population at large treated with antiplatelet agents and/or oral anticoagulants. The current guideline also includes recommendations and a discussion of thromboprophylactic strategies for all patients following traumatic injury. The most significant addition is a new section that discusses the need for every institution to develop, implement and adhere to an evidence-based clinical protocol to manage traumatically injured patients. The remaining recommendations have been re-evaluated and graded based on literature published since the last edition of the guideline. Consideration was also given to changes in clinical practice that have taken place during this time period as a result of both new evidence and changes in the general availability of relevant agents and technologies. CONCLUSIONS: A comprehensive, multidisciplinary approach to trauma care and mechanisms with which to ensure that established protocols are consistently implemented will ensure a uniform and high standard of care across Europe and beyond.

The STOP the Bleeding Campaign.

According to the World Health Organization, traumatic injuries worldwide are responsible for over 5 million deaths annually. Post-traumatic bleeding caused by traumatic injury-associated coagulopathy is the leading cause of potentially preventable death among trauma patients. Despite these facts, awareness of this problem is insufficient and treatment options are often unclear. The STOP the Bleeding Campaign therefore aims to increase awareness of the phenomenon of post-traumatic coagulopathy and its appropriate management by publishing European guidelines for the management of the bleeding trauma patient, by promoting and monitoring the implementation of these guidelines and by preparing promotional and educational material, organising activities and developing health quality management tools. The campaign aims to reduce the number of patients who die within 24 hours after arrival in the hospital due to exsanguination by a minimum of 20% within the next 5 years.

Lactate quartile concentration and prognosis in severe sepsis and septic shock.

Introduct ion The Surviving Sepsis Campaign (SSC) indicates that a lactate (LT) concentration greater than 4ımmol/l indicates early resuscitation bundles. However, several recent studies have suggested that LT values lower than 4ımmol/l may be a prognostic marker of adverse outcome. The aim of this study was to identify clinical and analytical prognostic parameters in severe sepsis (SS) or septic shock (ShS) according to quartiles of blood LT concentration. Methods A cohort study was designed in a polyvalent ICU. We studied demographic, clinical and analytical parameters in 148 critically ill adults, within 24ıhours from SS or ShS onset according to SSC criteria. We tested for diı erences in baseline characteristics by lactate interval using a KruskalıWallis test for continuous data or a chi-square test for categorical data and reported the median and interquartile ranges; SPSS version 15.0 (SPSS Inc., Chicago, IL, USA). Results We analyzed 148 consecutive episodes of SS (16%) or ShS (84%). The median age was 64 (interquartile range, 48.7 to 71)ıyears; male: 60%. The main sources of infection were respiratory tract 38% and intra-abdomen 45%; 70.7% had medical pathology. Mortality at 28ıdays was 22.7%. Quartiles of blood LT concentration were quartile 1 (Q1): 1.87ımmol/l or less, quartile 2 (Q2): 1.88 to 2.69ımmol/l, quartile 3 (Q3): 2.7 to 4.06ımmol/l, and quartile 4 (Q4): 4.07ımmol/l or greater (Tableı1). The median LT concentrations of each quartile were 1.43 (Q1), 2.2 (Q2), 3.34 (Q3), and 5.1 (Q4) mmol/l (Pı<0.001). The diı erences between these quartiles were that the patients in Q1 had signiı cantly lower APACHE II scores (Pı=ı0.04), SOFA score (Pı=ı0.024), number of organ failures (NOF) (Pı<0.001) and ICU mortality (Pı=ı0.028), compared with patients in Q2, Q3 and Q4. Patients in Q1 had signiı cantly higher cholesterol (Pı=ı0.06) and lower procalcitonin (Pı=ı0.05) at enrolment. At the extremes, patients in Q1 had decreased 28-day mortality (Pı=ı0.023) and, patients in Q4 had increased 28-day mortality, compared with the other quartiles of patients (Pı=ı0.009). Interestingly, patients in Q2 had signiı cant increased mortality compared with patients in Q1 (Pı=ı0.043), whereas the patients in Q2 had no signiı cant diı erence in 28-day mortality compared with patients in Q3. Conclusion Adverse outcomes and several potential risk factors, including organ failure, are signiı cantly associated with higher quartiles of LT concentrations. It may be useful to revise the cutoı value of lactate according to the SSC (4 mmol/l).

Activated protein C consumption and coagulation parameters in severe sepsis and septic shock.

Introduction Activated protein C (APC) deC ciency is prevalent in severe sepsis and septic shock patients. The aim of the study was to relate the anticoagulation activity evaluated by APC with other coagulation parameters adjusted to 28-day mortality. Methods A cohort study of 150 critically ill adults. Age, sex, sources of infection and coagulation markers within 24< hours from severe sepsis or septic shock onset, deC ned according to Surviving Sepsis Campaign (SSC) criteria, were studied. We analyzed APC activity using a hemostasis laboratory analyzer (BCS® XP; Siemens). A descriptive and comparative statistical analysis was performed using SPSS version 15.0 (SPSS Inc., Chicago, IL, USA). Results We analyzed 150 consecutive episodes of severe sepsis (16%) or septic shock (84%) admitted to the UCI. The median age of the study sample was 64 (interquartile range (IQR): 22.30.001). See Figure 1. Conclusion Low levels of PC are associated with poor outcome and severity in severe sepsis, and it is well correlated with antithrombin III and INR.
