A simple model for learning stereotactic skills in ultrasound-guided amniocentesis.

Abstract

Amniocentesis is an important procedure for antenatal diagnosis but requires stereotactic skill acquisition that may be facilitated by the use of a model. A model using a gelatin mold with "targets" within is created. The model is used to facilitate development of stereotactic skills and to demonstrate technique principles for ultrasound-guided amniocentesis. The model has been incorporated into an educational program for antenatal diagnosis within a residency and provides a reasonable simulation of clinical features important in learning genetic amniocentesis. The use of this model augments the learning of important skills needed for ultrasound-guided amniocentesis.
