Miller believes that for optimum results in narcoanalysis the drug to be used should not only lift psychic inhibition, but should also have a minimum sleep-producing effect and should not slow up the flow of ideas and speech productivity. The formula which gave excellent results was a solution of amytal in ethyl alcohol (20 to 25 cc. of 15% alcohol solution and 2 to 3¾ grains of amobarbital sodium). With small doses verbal productivity was increased, favorable rapport achieved, and excessive narcosis avoided. In contrast to amytal or pentothal alone, the combined alcohol-amytal solution did not depress circulation or respiration, produced a greater emotional catharsis during interviews, and recovery of motor coördination and mobility occurred more rapidly.
