Miniaturised ultrasound evaluation at the bedside

Abstract

Abstract Purpose “Point-of-Care Ultrasound” (POCUS) is now a familiar term. Although the European Federation of Societies for Ultrasound in Medicine and Biology (ESFUMB) published a position paper about its usage (Nielsen et al. in Ultraschall Med 40(1):30–39. https://doi.org/10.1055/a-0783-2303, 2019), there has not been much scientific focus on its utility in uro-nephrological clinical practice thus far. The aim of this study was to evaluate the present usage of pocket ultrasound devices at the bedside. Methods 27 investigators (all medical doctors with at least 6 months of experience in sonography) performed 280 bedside examinations using a pocket ultrasound device for common clinical issues. Results The most frequent indications included evaluation of hydronephrosis (147), volume management including assessment of dimension of the vena cava inferior (IVC) (195), detection of pleural, pericardial and abdominal effusions (113) as well as residual urine (52). In 90%, specific clinical questions were effectively answered by the pocket ultrasound device alone. Conclusions POCUS can be useful in the uro-nephrological field. In the hands of an experienced investigator, it saves time and, when it is realised that departmental ultrasound is not cheap, there is also an economic benefit with applicability within both inpatient and outpatient clinic settings. While acknowledging its technical limits, pocket ultrasound devices may nevertheless be helpful in targeted situations for triage or for bedside follow-up exams after earlier high-end ultrasound-based diagnosis.
