    Notes: The spatial distribution of Mg solute in polycrystalline, single-phase Al2O3 has been obtained, using a secondary ion imaging technique. Segregation of Mg to the Al2O3 grain boundaries is clearly observed—strong evidence that the principal role of MgO is to reduce the grain boundary mobility via a solute-drag mechanism. In addition, Mg (dopant) and Ca (impurity) are shown to cosegregate, shedding further light on magnesium's ability to stabilize microstructural evolution in Al2O3. © 1995 American Institute of Physics.

    Notes: A study involving 2738 patients in 15 hospitals in the United Kingdom was undertaken to evaluate the effect of simple methods of pain assessment and management on postoperative pain. The study consisted of four parts: a survey of current practice in each hospital; a programme of education for staff and patients regarding pain and its management; the introduction of formal assessment and recording of pain and the use of a simple algorithm to allow more flexible, yet safe, provision of intermittent intramuscular opioid analgesia; and a repeat survey of practice. One hospital from each of the former health regions of England and Wales was selected for inclusion in the project. Hospitals included representatives of different size units (university, large and small district general hospitals). As a result of the study, there was an overall reduction in the percentage of patients who experienced moderate to severe pain at rest from 32% to 12%. The incidence of severe pain on movement decreased from 37% to 13% and moderate to severe pain on deep inspiration from 41% to 22%. Similar decreases were seen in the incidence of nausea and vomiting. There was also a slight reduction in the incidence of postoperative complications. This study shows that simple techniques for the management of postoperative pain are effective in reducing the incidence of pain both at rest and during movement and should form part of any acute pain management strategy.

    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.

    Notes: The induction characteristics of sevoflurane in nitrous oxide and oxygen were compared with sevoflurane in oxygen alone and a propofol infusion. A vital capacity technique was used for the gaseous induction groups using a Mapleson A system and a 4-litre reservoir bag. Four end-points of anaesthesia were recorded: time to cessation of finger tapping, time to loss of eyelash reflex, time to jaw relaxation and time to regular settled breathing after laryngeal mask airway insertion. We also recorded sequential blood pressure and pulse rate, the incidence of adverse airway events and the acceptability of the induction technique. Propofol had a faster time to cessation of finger tapping (p 〈0.05) and jaw relaxation (p 〈0.01). These differences disappeared with the final induction stage and sevoflurane in nitrous oxide and oxygen had the faster time to regular settled breathing, though this did not reach statistical significance. Cardiovascular stability was good and comparable in all groups. There were few adverse airway events in any group and none caused oxygen saturation to fall below 96%. There was more excitation in the gaseous induction groups, though this did not interfere with induction. Patient satisfaction with induction was high.

    Notes: Five hundred members of the Obstetric Anaesthetists Association were surveyed regarding their technique for identification of the epidural space. Eighty-one per cent of the questionnaires were returned completed. Fifty-nine per cent of respondents first learned a loss of resistance to air technique, 33.4% to saline and 7.4% another technique. Presently, 37.1% and 52.7% use only a loss of resistance to air or saline, respectively. Six per cent use both techniques and 3.2% use other techniques. Twenty-eight per cent taught a loss of resistance to air, 57.2% taught a loss of resistance to saline and 12.9% taught both techniques. Twenty-three per cent changed from a loss of resistance to air, to a saline technique, and 4.2% vice versa. Forty-seven per cent of those using air felt that loss of resistance to air was not associated with a clinically significant difference in the incidence of accidental dural puncture compared with saline.
