SummaryA computerised database of operating theatre activity was used to estimate the costs of regional and general anaesthesia for varicose vein and inguinal hernia surgery. Data retrieved for each procedure included the anaesthetic technique and drugs used, and the duration of anaesthesia, surgery and recovery. The costs of anaesthetic drugs and disposables, salary costs of the anaesthetic personnel and maintenance costs for anaesthetic equipment were considered. Drugs and disposables accounted for < 25% of the total cost of an anaesthetic. Anaesthetic times were 5 min longer for regional anaesthesia, but recovery times were 10 min shorter following regional anaesthesia for varicose vein surgery. Staff costs were dependent on the length of time each staff member spent with the patient. Although the number of cases was small, provision of a field block and sedation for inguinal hernia repair was considerably cheaper than other anaesthetic techniques.Keywords Anaesthetic costs: regional; general. Cost containment has become a priority in all areas of health care. Clinicians must work within tightly controlled budgets in spite of increasing demand for services, expectations of higher standards, and the introduction of new drugs and techniques. A common view is that anaesthetic costs are insignificant because they are a relatively small component of the total for each surgical episode. This is superficially true; the Audit Commission reported that anaesthetic services comprised only 3% of NHS trust expenditure [1]. However, this adds up to a large sum of money across the service. Anaesthesia for any surgical procedure involves a wide choice of drugs, techniques and monitoring procedures, each with very different cost implications. Selection of any particular method must be determined by the relative costs, as well as the clinical benefits, if the challenge of providing highquality care within limited resources is to be met.The cost of each anaesthetic is the sum of a number of components. Information about the price of drugs (the commonest focus for debate) is readily available, but choices based solely on drug acquisition costs ignore many other factors that contribute to the cost of an anaesthetic, including capital and recurrent expenditure on equipment, the prices of disposable equipment, and the salaries of the anaesthetist, anaesthetic assistant and recovery staff. Personnel costs are dependent on the time spent by the patient in the anaesthetic room, operating theatre and recovery area, each of which may be affected by the anaesthetic technique or drugs used. This study used data from a computerised database of operating theatre activity to compare the costs of general and regional anaesthesia for patients undergoing varicose vein and inguinal hernia surgery.

This article assessed anesthetists' ability to identify correctly a marked lumbar interspace in 100 patients undergoing spinal magnetic resonance imaging scans. Using ink, the first anesthetist marked an interspace on the lower spine and attempted to identify its level with the patient in the sitting position. The second anesthetist attempted to identify the level with the patient in the flexed lateral position. A marker capsule was taped over the ink mark and a routine scan performed. The actual level of markers ranged from 1 space below to 4 spaces above the level at which the anesthetist believed it to be. The marker was 1 space higher than assumed in 51% of cases and was identified correctly in only 29%. Accuracy was unaffected by patient position (sitting or lateral), although it was impaired by obesity and positioning of the markers high on the lower back. The spinal cord terminated below L1 in 19% of the patients. This, together with the risk of accidentally selecting a higher interspace than intended for intrathecal injection, implies that spinal cord trauma is more likely when higher interspaces are selected. Comment by Alan Kaye, M.D. Previous studies have demonstrated inaccuracies regarding identification of lumbar interspaces. This study by Broadbent et al involved 104 patients scheduled for lumbar magnetic resonance imaging and essentially anesthesiologists were asked to mark with washable ink the skin overlying any interspace on the lower spine after palpation of the lumbar region. Different positions were evaluated including sitting and lateral. Only 29% were demonstrated to be correct through magnetic resonance imaging. Within the lumbar region, there were tremendous errors by the anesthesiologist at all levels. Further, a common mistake included the assumption of location based on the landmark provided from the iliac crest. Therefore, with the potential of neurological damage from misidentification of the vertebral column, the authors recommend lower rather than higher sites when more than 1 site is identified. The authors provide a clever investigation; however, this is a relative small study population and there is little mention of the variation existing within the population studied. However, this study suggests that if an option exists as to which lumbar space to enter, the lower would seem safer and more prudent to minimize the potential of neurologic injury.
