Six healthy adult female volunteers were used in the quantitative assessment of their respiratory responses following intravenous administration of meperidine and diazepam. A modified rebreathing CO2-challenge technique of Eckenhoff et al.,5 previously reported,6 was used for this purpose.

The CO2 stimulus response curves obtained confirmed the respiratory depressant response following the use of 0.5 mg./kg. meperidine. Diazepam, at dose levels up to 0.066 mg./kg., produced no statistically significant respiratory response to carbon dioxide detectable by this method (p < 0.025).
