INTRALUMINAL LEAD OF THE GASTRIC ACTION POTENTIAL WITH SUCTION NEEDLE ELECTRODE

概要

In the past, extraluminal leading of the gastric action potentials had been used experimentally and clinically with satisfactory results, while intraluminal leading had been attempted only by a few researchers because of technical difficulty and the electromyograms obtained with this method were not entirely satisfactory.<BR>A new suction needle electrode was devised by us to lead the gastric action potentials intraluminally. Electromyograms of the stomach from 10 human beings and 10 dogs led with this electrode proved to be quite similar to those led with the the needle electrode from the serosal aspect of the stomach.<BR>With this method, constant and satisfactory electromyograms may be recorded from the mucosal aspect of the stomach, thus eliminating general anesthesia and laparotomy. Easier and wider use of electromygoraphy of the stomach in the clincial as well as research field is expected.
