Prehospital ultrasound

[Extract] Focused ultrasound is an emerging tool that non-imaging specialists are increasingly using in hospital to assess and monitor patients. The use of ultrasound under these circumstances is directed towards answering a specific clinical question, or improving the safety of a specific clinical procedure. Ultrasound provides real-time imaging of many structures otherwise 'invisible' to the practitioner and is not limited by environmental noise.\ud \ud The development of lighter, stronger, cheaper and more portable ultrasound devices means that focused ultrasound may now be employed in the prehospital environment (Figure 12.1)

EFSUMB Clinical Practice Guidelines for Point-of-Care Ultrasound:Part One (Common Heart and Pulmonary Applications) SHORT VERSION

Aims To evaluate the evidence and produce a summary and recommendations for the most common heart and lung applications of point-of-care ultrasound (PoCUS). Methods We reviewed 10 clinical domains/questions related to common heart and lung applications of PoCUS. Following review of the evidence, a summary and recommendation were produced, including assignment of levels of evidence (LoE) and grading of the recommendation, assessment, development, and evaluation (GRADE). 38 international experts, the expert review group (ERG), were invited to review the evidence presented for each question. A level of agreement of over 75 % was required to progress to the next section. The ERG then reviewed and indicated their level of agreement regarding the summary and recommendation for each question (using a 5-point Likert scale), which was approved if a level of agreement of greater than 75 % was reached. A level of agreement was defined as a summary of “strongly agree” and “agree” on the Likert scale responses. Findings and Recommendations One question achieved a strong consensus for an assigned LoE of 3 and a weak GRADE recommendation (question 1). The remaining 9 questions achieved broad agreement with one assigned an LoE of 4 and weak GRADE recommendation (question 2), three achieving an LoE of 3 with a weak GRADE recommendation (questions 3–5), three achieved an LoE of 3 with a strong GRADE recommendation (questions 6–8), and the remaining two were assigned an LoE of 2 with a strong GRADE recommendation (questions 9 and 10). Conclusion These consensus-derived recommendations should aid clinical practice and highlight areas of further research for PoCUS in acute settings
