Generally, most pediatric patients I’ve seen despise “needles.” Fortunately, they general love ipads and various other forms of technology. This particular study combines the two. Looking at 151 skin & soft tissue infections among 148 patients, the initial treating physician recorded their initial assessment as to whether or not there was a drainable collection, which was followed by a second physician who was blinded to the first assessment, doing an ultrasound.
In the above referenced study, POCUS for an abscess had a sensitivity of 95% and specificity of 87%. Physical exam sensitivity was 84% with 60% specificity. Add in this lit review – which also shows a higher sensitivity for US, and – especially for peds who run and scream at the suggestion of an I&D – there is no reason to not be doing more POCUS in these situations.
