    Notes: In this prospective randomised study, pruritus and pain were evaluated in patients undergoing abdominal surgery in which intrathecal morphine was administered. Each patient received intrathecal morphine 0.3 mg prior to induction, followed by a standard anaesthetic. The patients were randomly allocated to one of two groups. One group received 100 mg of rectal diclofenac immediately post-induction. Patients receiving diclofenac had significantly lower pruritus scores at 30 min (p = 0.0076), 2, 4, 8 and 24 h postoperatively, as well as significantly reduced pain scores at each time point (p 〈 0.0001 at each study interval). Morphine consumption in the first 24 h was also significantly lower in this group. In conclusion, rectal administration of diclofenac significantly reduces the incidence and severity of postoperative pruritus. It also significantly reduces pain and further analgesic requirements postoperatively.

    Notes: We describe the stages of non-REM sleep induced by anaesthesia with sevoflurane 8% in oxygen and relate these stages to clinical eye positions. We explored John Snow's observation (1847) that ‘when voluntary movement ceases, with the eyes fixed in an upward gaze during the gas induction of anaesthesia, the patient is protected against the risk of mental suffering’ (awareness). Unpremedicated ASA 1 patients undergoing elective tonsillectomy were studied using EEG polysomnographic principles and clinical eye movement tracking. The results expressed as median and range were: latency to stage 1 sleep 4.5 min [2.5–7.5], stage 2 sleep 5 min [3.5–8.5], stage 3 sleep 5.5 min [4–12] and stage 4 sleep 6 min [4.5–15.5]. Eye position 5, the point of no further eye movement, was reached after 9 min [5.5–18.5]. This was significantly longer than the time taken to reach the stage 4 sleep EEG, p 〈 0.01, supporting Snow's observation and encouraging investigation into eye movement tracking technology as a potential monitor of anaesthetic depth.

    Notes: In this prospective randomised study, pruritus and pain were evaluated in patients undergoing abdominal surgery during which epidural fentanyl was administered. All patients had an epidural catheter inserted at the time of surgery. Epidural fentanyl 100 μg was administered intra-operatively and infused at a concentration of 2 μgml−1 for 48 h postoperatively. All patients received a standard anaesthetic and, in addition, the study group had a 20 mg bolus of tenoxicam intravenously, intra-operatively. Patients receiving tenoxicam demonstrated significantly lower pruritus and pain scores at 30 min, 2, 4, 8 and 24 h postoperatively as well as reduced pethidine requirements for breakthrough pain in the first 24 h. In conclusion, tenoxicam 20 mg significantly reduces the incidence and severity of postoperative pruritus in patients who received peri-operative epidural fentanyl. In addition, it significantly reduces pain and further analgesic requirements postoperatively.

    Notes: Summary Intra-articular morphine (5 mg in 25 ml) was administered to patients for post-operative analgesia following arthroscopic knee surgery. At various time intervals, 30 min to 4 h post morphine, venous blood samples were taken in order to determine plasma levels of morphine and its primary metabolites, morphine-3-glucuronide and morphine-6-glucuronide. Measurable amounts of morphine and morphine-3-glucuronide were found in the plasma of 7/10 patients whereas morphine-6-glucuronide was detected in only 2/10 patients. The plasma levels of morphine were lower than that regarded sufficient for post-operative analgesia in all but two patients, indicating a possibility of peripheral analgesia. [p]In addition, synovial biopsy samples were assayed for the presence of opioid binding sites. Tissue samples from 11 different patients were analysed and 6/11 exhibited specific binding of [3H]naloxone, indicating the presence of opioid binding sites/receptors. The receptor type (i. e. μ, δ- or k-) is at present unknown. [p]Taken together, these data provide evidence that locally administered opiates can act on specific opioid receptors in the synovium to mediate analgesia.
