[Electrical nerve localization: non-linear relationship between intensity and pulse duration to stimulate a nerve].
When performing a peripheral nerve block, the current allowing local anaesthetic injection is between 0.3 and 0.5 mA. It has never been assessed if such a threshold remains the same whatever be the pulse duration. The aim of this study was to determine the minimal current required to stimulate a nerve while different pulse durations were applied, and to evaluate the importance of the placement of the cutaneous electrode. ⋯ The relationship between intensity and pulse duration is not linear. Moreover, a low charge of current does not seem to be appropriate with pulse duration equal or superior to 300 micros. The location of the cutaneous electrode does not seem to be important.

Review[E-learning in medicine: appraisal and perspectives. Example of an educational website about echocardiography in anaesthesia, intensive care and emergencies: www.echorea.org].
Internet is a mode of quick and more and more easily approachable communication. Its use as support of education allows an enrichment of the master-pupil relation by its availability, its interactivity and the multiplicity of its means. Medicine benefits particularly from these new means of virtual companionship. This review offers to characterize means and constraints of the use of Internet in medical education, and to illustrate these purposes by an example of site created for the teaching of ultrasound use in anaesthesia, intensive care and emergency.

Comparative Study Clinical Trial[Clinical usefulness of new-generation pulse oximetry in the paediatric cardiac surgery setting].
Arterial oxygen saturation (SaO(2)) monitoring using pulse oximeter (SpO(2)) is mandatory in the intensive care unit. The aim was to assess bias and precision of new (SpO(2)ng) and old (SpO(2)og) pulse oximeter technologies in the postoperative period following pediatric cardiac surgery in cyanotic children. ⋯ SpO(2)ng is more accurate and more reliable than SpO(2)og for SaO(2) monitoring in the postoperative period following pediatric cardiac surgery in cyanotic children.
