Comparison of the effects of atropine sulfate and ethanol on performance. 1986

J A Dellinger, and H L Taylor, and B C Richardson

The flight simulator performance decrements resulting from atropine injections were compared to similar decrements resulting from ethanol toxicosis. There were 20 volunteers that received 0.0, 0.5, 1.0, 2.0, and 4.0 X 75 kg-1 of atropine sulfate under double-blind conditions. The performance decrements at each atropine sulfate treatment level for each subject were determined by computing root mean square (RMS) deviations for five flight performance variables. The data set from a previous study concerned with the effects of ethanol on pilot performance was reanalyzed, and the decrements for the five variables at the 0.082% blood alcohol level (BAL) were computed. Probit analysis was used to estimate the effective dose (ED50) at which 50% of the subjects in the atropine sulfate experiment were expected to display decrements in excess of those observed for the 0.082% BAL. The ED50 was 3.12 mg of atropine sulfate.
