[Transcutaneous cerebral electric stimulation by Limoge current during labor]

In order to test the analgesic efficacy of Anesthelec (transcutaneous cranial electrical stimulation with Limoge currents) during labour and delivery, a double blind study was performed in 20 cases for whom analgesia was necessary. In 10 cases Anesthelec was used with the Limoge currents on and in 10 cases as a sham. Labour and delivery were carried out by a medical team different from that which set up the Anesthelec. The results showed that this method, with or without nitrous oxide inhalation, decreased by 80% the number of epidural and general anaesthesias that would otherwise have been unavoidable. To define the effects of this new method, maternal and foetal parameters of 50 deliveries carried out under Anesthelec were compared with 50 deliveries carried out under epidural analgesia. Anesthelec was used only if analgesia was required. This study was a retrospective comparison between two similar non paired series. Despite the fact that analgesia obtained with Anesthelec was less powerful than with epidural analgesia, this method showed many advantages: total safety for the child and the mother, easy utilization, shorter labour time, decreased number of instrumental extractions and potentially reduced costs. Good acceptance and satisfaction for the mother should allow a rapid evolution of this new method.
