Lumbar Plexus Blocks and Lumbar Plexus Nerve

To the Editor: 1. Oximeters are often sold at considerable discounts from the list prices; some manufacturers have offered threefor-the-price-of-two incentives, while others offer large discounts for volume purchasers. Therefore, we felt it more appropriate for purchasers to determine their final cost for the oximeter(s) in which they are interested, rather than for us to tabulate the list prices published by the manufacturers. 2 . Any attempt to include price in our overall rankings would have required that we somehow relate cost to oximeter performance. This relationship would be expected to vary between institutions depending upon the availability of funding; therefore, the general applicability of our findings would be decreased.
