New training model for installing ultrasound-guided drainages

Abscesses and circumscribed collections of fluid are frequently found as complications of infectious diseases or surgery. Drainage is often indicated. We created a new, self- and easy-to-make model to learn and improve competence in installing ultrasound-guided drainage of abscesses. For this purpose, several water balloons were placed in a plastic box which then was filled with instant custard powder mixed with water. Computed tomography (CT) of this box was performed. Experienced (n=4) and not experienced examiners (n=4) drained the balloons using either ultrasound-guidance alone or volume navigation with imag…
