[Clinical effectiveness of naloxone in acute ethanol intoxication]

The first articles trying to link the effects of ethyl alcohol with those of opiates appeared in 1970. The first case of reversion from ethylic coma due to naloxone was described in 1978. Since then, many authors have reported different results related to the effectiveness of opiate antagonists in this clinical situation, without any of the studies showing a beneficial effect from its use. The purpose of the present study is to perform a double-blinded clinical trial with placebo to evaluate naloxone's clinical effectiveness in severe ethylic intoxication, using the Glasgow test (GT) to measure the level of consciousness. Treatment was randomly assigned to 38 patients of whom 18 received 2 mg of naloxone and 20 a placebo. Among the results, it was found that the best approximation of the level of alcoholemia responsible for ethylic coma, without the involvement of other toxic psychotropes, was made using the Glasgow test, especially in patients who are occasional drinkers. It was shown that naloxone indeed lacks effectiveness in ethylic coma, raising the level of consciousness only one or two points in the Glasgow test for the 15 to 45 minutes after its administration and primarily in the group of patients with the lowest levels of consciousness.
