Analgesia after caesarean section. The use of rectal diclofenac as an adjunct to spinal morphine.
A double-blind placebo-controlled study was performed to assess the analgesic effect of rectal sodium diclofenac 100 mg after Caesarean section using subarachnoid hyperbaric bupivacaine 0.5% and morphine 0.2 mg. During the 48 h follow-up period, both placebo and diclofenac groups had comparable analgesia as measured by visual analogue scores (VAS) at rest and on movement. However, diclofenac prolonged the mean time to first analgesia by more than 5 h from 13 h 45 min in the placebo group to 18 h 58 min (p < 0.03). The incidence of side effects (nausea, vomiting, itching, excessive lochia loss and the need for additional analgesia) were comparable in each group.

A comparison of diclofenac with ketorolac for pain relief after knee arthroscopy.
We performed a double-blind controlled trial to compare the analgesic effect of two nonsteroidal anti-inflammatory drugs. We compared rectal diclofenac 100 mg given 1 h before induction of anaesthesia with intravenous ketorolac 10 mg given immediately before anaesthesia in 40 patients undergoing arthroscopy of the knee as day cases. A visual analogue scale was used to assess pain prior to discharge. Pain, analgesic consumption, sleep disturbance and restriction of activities were recorded by telephone enquiry 24 h after surgery. There was no difference in the pain parameters, sleep disturbance, or restriction of activity between groups. We suggest that ketorolac 10 mg intravenously and diclofenac 100 mg rectally provide comparable postoperative analgesia in the first 24 h after arthroscopy of the knee.

A prospective study to assess the demand for a high dependency unit.
We performed a prospective study in our teaching hospital to determine the demand for a High Dependency Unit where none had existed before. An admission criteria protocol was designed for medical and surgical patients and this was used in an intense surveillance of 22 acute wards over 2 weeks. It was predicted that a high dependency unit of eight beds would operate to capacity 50% of the time. An analysis of this type over a short period of time using similar admission criteria could be used to assist in the prediction of the necessary size of a High Dependency Unit facility in any hospital.

Local anaesthesia for cannulation. Has practice changed?
A questionnaire study was undertaken to assess the influence of recently published, simple and conclusive research on the practice of anaesthetists in four centres. The research had clearly demonstrated the benefit of subcutaneous infiltration of local anaesthetic in reducing the pain of intravenous cannulation. Of the 81% who responded, 71% were aware of the research; 43% of these anaesthetists had altered their clinical practice as a result of the research and 73% used local anaesthesia for cannulae of 18 gauge or less, compared with only 46% of those who were unaware of the research. Practice comparisons were made between centres and grades of anaesthetist. Senior house officers were significantly less likely to be aware of the research than other grades. Anomalies were identified between the apparent awareness of the research and routine practice agreeing with the study findings. The value of research and the incorporation of clinical findings into everyday practice is discussed.

Use of ketorolac in the prevention of suxamethonium myalgia.
We have evaluated the effect of ketorolac in the prevention of suxamethonium myalgia. Sixty ASA I patients who presented for extraction of wisdom teeth as day cases were allocated randomly to one of three equal groups. Patients received either 0.9% saline (placebo), atracurium 0.05 mg kg-1 i.v. or ketorolac 10 mg i.v., 3 min before induction of anaesthesia. Follow-up postal questionnaires (97% response rate) at 48 h showed no reduction in the incidence of myalgia after ketorolac pretreatment compared with saline. The use of atracurium reduced the incidence of myalgia by 60% (P < 0.001) and the severity of fasciculations (P < 0.001). There was no difference in the severity of fasciculations between the saline and ketorolac groups. Intubating conditions were comparable in the three groups.
