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

Background: Amniocentesis is an important procedure for antenatal diagnosis but requires stereotactic skill acquisition that may be facilitated by the use of a model. Technique: 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. Experience: 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. Conclusion: The use of this model augments the learning of important skills needed for ultrasound-guided amniocentesis.
