Bupivacaine (Marcain ®) spinal anesthesia has been used for 10 years in Japan and is said to be highly suitable for orthopaedic and urological operations in the elderly, especially when compared to the spinal anesthesia with other local anesthetics. However, there is some argument against its use because the Marcain sold in Japan contains preservatives. Moreover, Marcain is not adapted for spinal anesthesia by the Ministry of Health and Welfare. Nevertheless, it is widely used especially in orthopaedic surgery. We sent questionnaires to 1, 416 registered hospitals of The Japanese Orthopaedic Association and made inquiries about the use of bupivacaine for spinal anesthesia. We received answers from 870 hospitals (with a reply rate of 61.4%). In 85.7% of these hospitals orthopaedic surgeons anesthetize their patients, before performing surgical operations on their hips or lower extremities. In 41.4% of these hospitals, they use Marcain for spinal anesthesia. During the 6 month period between January and June of 1988, 39, 690 patients were anesthetized by orthopaedic surgeons (in those 870 hospitals). 27, 287 cases were for spinal anesthesia and Marcain spinal was used in 7, 321 cases. The most common side-effects were hypotension, but its degree was mild and controllable. No neurological side-effects were reported. Ninty point fire percent of the surgeons who used the Marcain spinal anesthesia replied that they need preservativefree bupivacaine for spinal anesthesia.
