L'état de L'ouïe Après L'Administration des Remèdes Narcotiques

Abstract

SUMMARY

The influence of narcotics on the cochlear organ is not well known. The author compared the results of the pure tone and the subjective speech threshold after administering 1 ml of 0.01 morphine or of scophedal to persons (1) with normal hearing; (2) with conductive deafness; and (3) with perceptive deafness.

Morphine has no influence on the pure tone and speech discrimination threshold. Yet an increase in intensity above the threshold induces better speech discrimination in persons with unimpaired hearing and in those with conductive deafness. The results of hearing examination after administration of scophedal are very difficult to interpret because of their variety and instability.
