The effect of maintained treatment with salicylo-acetic acid (1.5 g/day) on the thrombelastogram was examined in the venous blood from 18 accidental patients.

Some of the patients revealed prolonged times for reaction and formation of coagula, thus discreet influencing the thrombelastogram might be supposed.
