dc.description.abstractPharmacokinetic modelling of estimated central nervous system concentrations was used to devise the optimal mixture of morphine and alfentanil for the treatment of postoperative pain. Modelling revealed that an intravenous opioid pain protocol using an alfentanil−morphine mixture in the proportions 0.75 : 10 mg would provide a profile of analgesia of rapid onset, yet slow offset. The regimen was evaluated in 58 patients in the recovery ward who were randomly allocated to receive analgesia using pain protocols with either morphine or the mixture. Groups were well matched for age, weight and initial pain scores. The mean (SD) time to patient comfort was 27.6 (20.2) min for the mixture and 41.2 (18.6) min for morphine (p = 0.01). Multiple regression analysis revealed that that initial pain score (p = 0.009) and drug group (p = 0.02), but not age, weight or gender were independent predictors of the time to comfort. Drug group was not a significant predictor of adverse effects.
