Background Learning ultrasound‐guided invasive procedures in fetal medicine can be done either on training models or directly on patients. Amniocenteses, cordocentesis, and chorionic villous sampling are associated with more complications at the beginning of the learning curve. It is therefore essential to optimise the teaching and reduce the length of the learning curve. We studied the learning curves of 8 inexperienced registrars in ObGyn with and without the use of a new electronic guidance system. Method 8 medical students performed 100 invasive procedures (cordocentesis) using a specially designed training model. Four students used the ultrasound‐assisted free hand technique and four students used the same technique but assisted by the electronic guidance system. We studied the overall duration of the procedure and the proportion of this time the student is in control of the needle (the entire needle is visualised on the ultrasound screen). Results The new electronic guidance system reduces the learning curve of ultrasound‐assisted invasive procedures on training models, but increases the length of the procedure. Conclusion The new electronic guidance system can help teaching junior doctors in ultrasound‐assisted invasive procedures in fetal medicine.
