The respiratory effects of meptazinol 1 mg kg1 have been compared with those of pethidine 0.5 mg kg1 and 1 mg kg1 in a double-blind trial in 30 patients undergoing arthroscopic meniscectomy under general anaesthesia. Respiratory depression was seen in all treatment groups. Pethidine 1 mg kg1 produced respiratory depression which was greater than that produced by meptazinol 1 mg kg1. The least depressant respiratory effects were seen in the group receiving pethidine 0.5 mg kg1. We submit that the measurement of tidal volume enhances the assessment of the respiratory effects of analgesic drugs during anaesthesia.
