To implement a vaginal delivery of the second twin simulation program for obstetric and gynecology residents, to reduce maternal-fetal mortality in the management of twin pregnancies in the delivery room.

A prospective education program. The session consisted of a theoretical part, a practical part on a mannequin and an evaluation. The model was designed in a simple and reproducible way. The simulation evaluation was done at several levels according to the validated Kirkpatrick model.

A tertiary level university maternity hospital.

Ten obstetric and gynecology residents participated.

The resident's personal feelings about their ability to perform the maneuvers increased significantly after participation in the simulation session. Their technical skills in performing the maneuvers were assessed in a second step. The majority of the participants considered the model realistic and the session useful. All agreed that the simulation was an essential part of their learning process.

A simulated vaginal delivery of the second twin session allows residents to be safely trained in these obstetrical maneuvers, which can be difficult to teach and perform.
