    Notes: In this study the subjective effects (sedation and mood) of subanaesthetic doses of propofol were examined in 28 healthy male volunteers. A computer model was used to predict the infusion profiles necessary to obtain steady state propofol plasma concentrations of0.3μg.ml-1, 0.6 μg.ml-1, 0.9 μg.ml-1. Objective measures of sedation from saccadic eye movement and choice reaction time gave significant dose responses at each level but a battery of psychometric tests failed to show dose-related subjective responses. Of particular note in the subjective data is the lack of a difference between groups or even of a consistent trend within the data. This suggests that a low concentration of propofol in plasma does not induce euphoria or a sense of well-being. The anecdotal evidence available for mood changes with propofol therefore remains unsubstantiated.

    Notes: We assessed the effectiveness of intra-articular solutions of morphine, bupivacaine with adrenaline and a combination of both, compared with placebo in facilitating mobilisation and reducing postoperative pain and analgesic requirements for 24 h after operation. Forty patients undergoing arthroscopic knee surgery were studied in a double-blind, randomised, controlled trial. All treatments proved more effective than placebo in facilitating earlier mobilisation and in decreasing postoperative pain as measured by visual analogue scale. Morphine alone provided the best analgesia and significantly decreased analgesic consumption for 24 h after surgery. We conclude that 1 mg of intra-articular morphine provides effective pain relief following arthroscopic knee surgery and that the addition of bupivacaine is of no benefit.

    Notes: Sixty patients took part in a randomised, double-blind study to compare the analgesic and side effects of three opioid-containing solutions for patient-controlled epidural analgesia following abdominal surgery. Patients in group 1 received a solution containing bupivacaine 0.125% with fentanyl 10μg. ml−1, group 2 bupivacaine 0.125% with diamorphine 125μg. ml−1, group 3 pethidine 2.5 mg. ml−1. All groups received 4 ml.h−1 background infusion and 3 ml boluses every 20 min if necessary. There were no significant differences between the groups in visual analogue scale pain scores (p = 0.537) or volumes of solution used at 24 h (p = 0.351) or 48 h (p = 0.105). Motor block was significantly higher in group 2 (p 〈 0.004) and pruritis occurred significantly less in group 3 (p 〈 0.05). We conclude that these three solutions produce equivalent analgesia but that pethidine 2.5 mg. ml−1 may be associated with fewer side effects.
