The authors evaluated regional skin temperatures of the foot following the administration of a variety of local anesthetic nerve blocks with either Xylocaine (lidocaine hydrochloride) or Sensorcaine (bupivacaine hydrochloride). The study was carried out on ten randomized parallel groups of five subjects, each group being tested with one drug and one regional nerve block. The results indicated that both Xylocaine and Sensorcaine, when administered as a posterior tibial block, result in a significantly increased blood flow to the foot. Nerve blockade of the remaining nerves of the foot did not significantly increase the sympatholytic effect obtained by posterior tibial nerve block alone.
