Randomized Controlled Trial Clinical TrialIntravenous tenoxicam for analgesia following laparoscopic cholecystectomy.
In a double-blind, placebo-controlled clinical trial (power of 80% to detect a 30% reduction in morphine consumption, P < 0.05) we have determined that intraoperative intravenous administration of tenoxicam 40 mg during laparoscopic cholecystectomy, when compared with placebo, was associated with a significant reduction in consumption of morphine at 6 hours and 12 hours (P < 0.05) but not at 24 hours, when assessed by patient-controlled analgesia. Furthermore there was a significantly greater requirement for "rescue" analgesia with intramuscular morphine in the placebo group during the period of the study. There was no difference between the groups in pain scores, either at rest or on movement, nor in the incidence of nausea and vomiting. No patient in either group suffered a respiratory rate less than 8/min or oversedation at any time, and there were no other adverse effects.

This prospective study was designed to describe problems that arise when Aboriginal people undergo anaesthesia, in order to develop guidelines for anaesthetists who are not accustomed to treating Aboriginal people. Data were collected on 1122 consecutive different individuals undergoing anaesthesia at Royal Darwin Hospital, 24.5% of whom described themselves as Aboriginal. ⋯ Communication difficulties were more commonly reported in Aboriginal patients; the most common difficulty was apparent shyness or fear, rather than actual language difficulty. The results suggest that the treatment of Aboriginal people involves diagnosis and management of diverse preoperative medical problems, and that better management may be achieved by learning simple cultural strategies and by adding Aboriginal interpreters and health workers to the anaesthetic team.

Clinical TrialDepth of central venous catheter insertion in adults: an audit and assessment of a technique to improve tip position.
A technique of subclavian vein catheterization is described, tailored to the individual patient, to reduce the risk of right atrial placement with central venous catheter (CVC) insertion. Using data gathered retrospectively for Quality Improvement purposes, CVC tip location was assessed. The standard technique used in our cardiac anaesthesia unit at that time was to insert all CVCs to a depth of 15 cm from the skin. ⋯ The tailored method involved measuring the distance from the skin at which venepuncture occurred and using this distance to determine depth of CVC insertion. Using the tailored technique significantly decreases the frequency with which CVC tips enter the right atrium (P < 0.001). An advantage of the tailored technique is that the distance between the most proximal and the distal ports of multi-lumen CVCs is taken into consideration, reducing the risk of extravasation via the proximal port.

Case ReportsSpinal anaesthesia--the current trend towards narrow gauge atraumatic (pencil point) needles. Case reports and review.
Advances in manufacturing technology have led to the wider availability and affordability of narrow gauge atraumatic spinal needles. The use of these needles is the most effective method available for anaesthetists to reduce the incidence of post dural puncture headache. Their use in all circumstances however, may not be appropriate in light of the problems which may be associated. These problems are illustrated here by four case reports and a review of the literature.

A survey carried out by the Australian Society of Anaesthetists explored gender issues in the personal and professional lives of anaesthetists. Issues highlighted include training and career paths, combining anaesthetic training with domestic responsibilities, personal relationships, pregnancy and childrearing, private practice, part-time work, parental leave, the single anaesthetist, doctor spouses, sexual harassment, and negative attitudes in colleagues. Particular problems were identified in the training years, in part-time work, in private practice, and in combining parental and domestic responsibilities with a career in anaesthesia. Strategies to address relevant issues are discussed, with reference to the increasing proportion of women in medicine and anaesthesia.
