A new obstetric forceps for the training of junior doctors: a comparison of the spatial dispersion of forceps blade trajectories between junior and senior obstetricians.

Objective: The purpose of this study was to create a new instrument for the training of doctors in the use of forceps and to compare the trajectories of forceps blades between junior and senior obstetricians.

Study Design: We equipped a simulator and forceps with spatial location sensors. The head of the fetus was in an occipitoanterior location, at a "+5" station.

Birth simulator: reliability of transvaginal assessment of fetal head station as defined by the American College of Obstetricians and Gynecologists classification.

Objective: This study was undertaken to investigate the reliability of transvaginal assessment of fetal head station by using a newly designed birth simulator.

Study Design: This prospective study involved 32 residents and 25 attending physicians. Each operator was given all 11 possible fetal stations in random order.
