Sepsis-3, published in 2016, defined sepsis as ‘life-threatening organ dysfunction caused by a dysregulated host response to infection’. Instead of systemic inflammatory response syndrome (SIRS), calculating the Sequential Organ Failure Assessment (SOFA) score was recommended. The complexity of SOFA also led to the introduction of quick SOFA (qSOFA) as a bedside tool. The simultaneous removal of SIRS and introduction of qSOFA belies their significant differences, with SIRS having a high sensitivity but very low specificity, and qSOFA being very specific for a poor outcome, but having a lower sensitivity than SIRS. In the UK, the variables within qSOFA are collected on a regular and repeated basis, along with additional variables, as part of the National Early Warning Score (NEWS). A knowledge of SIRS, qSOFA and NEWS is of value in assessing patients with suspected sepsis, as discussed in this article.
Epinephrine (adrenaline) is commonly used by paramedics in a range of clinical scenarios. Its role in cardiac arrest scenarios is well established, but the indications for use in acute severe or life-threatening asthma are less well defined. This article reviews the evidence for the use of epinephrine in acute severe asthma and uses a case study to highlight some of the potential side-effects that clinicians need to be aware of.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
