[New trends and the influencing factors on the results of spinal anesthesia].
Since its introduction about a century ago, spinal anesthesia has been increasingly accepted by anesthesiologists. Recent studies are looking for an ideal local anesthetic. The influence of the type of anesthetic, its concentration, volume, dose, specific gravity, patient position, puncture site, injection speed, characteristics of cerebrospinal fluid and general condition of the patient are reviewed. New trends of spinal anesthesia including prolongation of the block by clonidine, pentazocine as a sole agent, and management of postspinal headache are also discussed. The review is based mainly on a computer-assisted search for articles published after 1960.
