Abstract
Successful spinal anesthesia with 0.5% plain bupivacaine was received by 340 consecutive patients. A small randomized study of 40 of these cases showed little difference between 3.5 and 3 ml; however, analysis of its use in 200 patients receiving 3.5 ml (mean block T [thoracic] 10.5 .+-. 1 segment) and 100 receiving 3 ml (T10 .+-. 0.5 segment) confirmed the impression that the smaller volume produced a more limited range of segmental block, which was desirable notably in the over-70-yr age group. The main complications were hypotension (14.1%) and headache (1.5%).
