1. Succinylcholine dichloride (SCC) is a valuable adjunct in electroshock therapy.2. SCC is one of the best muscle relaxants presently available.3. A number of methods of administering it are outlined. Our own is described and the more important technical points discussed.4. We have devised a simple test, which has made it possible for us to determine, at the time of the first treatment, the therapeutic dose required for the best muscle relaxation.5. Routinely with all patients undergoing electroshock therapy, our aim has been to cause only partial paralysis by using small doses of SCC. However, when used in the presence of fractures, we advise larger doses so that a complete, or nearly complete, muscular relaxation to the point of temporary paralysis is produced.6. We have not had a single fracture in 300 patients treated with our method.Abstract Teaser
