Pneumatic evoked potential. Sensory or auditive potential?

Study Aim: In this study, evoked potentials (EPs) to a pneumatic, innocuous, and calibrated stimulation of the skin were recorded in 22 volunteers.

Methods: Air-puff stimuli were delivered through a home-made device (INSA de Lyon, Laboratoire Ampère, CHU de Saint-Étienne, France) synchronized with an EEG recording (Micromed(®)).

Results: A reproducible EP was recorded in 18 out of 22 subjects (82% of cases) with a mean latency of about 120-130ms, and maximal amplitude at Cz.

Does forceps training on a birth simulator allow obstetricians to improve forceps blade placement?

Objective: The aim of this study was to evaluate whether forceps training on a birth simulator allows obstetricians to improve forceps blade placement.

Study Design: Analysis was based on 600 forceps blade placements performed by ten trainees on a simulator. The trajectories used by the trainees were assessed using reference spheres that reflected an optimal bimalar placement.

Simulation of an instrumental childbirth for the training of the forceps extraction: control algorithm and evaluation.

This paper presents the control algorithm implanted on the childbirth simulator BirthSIM in order to provide training to novice obstetricians. The forceps extraction is an obstetric manipulation learned by experience. However, nowadays the training is mainly provided during real childbirths.

Assessment of forceps use in obstetrics during a simulated childbirth.

Background: In obstetrics, manipulations are mainly learned during real deliveries. To minimize the risks linked to such training, we propose a childbirth simulator as a teaching tool in hospitals. More specifically, we focus on training with forceps during obstetric manipulation.

Design of a new instrumented forceps: application to safe obstetrical forceps blade placement.

Today, medical simulators are increasingly gaining appeal in clinical settings. In obstetrics childbirth simulators provide a training and research tool for comparing various techniques that use obstetrical instruments or validating new methods. Especially in the case of difficult deliveries, the use of obstetrical instruments-such as forceps, spatulas, and vacuum extractors-has become essential.
