title: Intramuscular Bupivacaine Injection for the Treatment of Oculomotor Paresis.
abstract: The main goal of this study is to examine the effect of intramuscular bupivacaine in oculomotor paresis, analyzing whether it is possible to obtain a stronger muscle contraction due to the muscle hypertrophy caused by the drug. An injection of 4.5 mL of a 0.50% solution of bupivacaine was administered in the paretic muscle of three patients. Magnetic resonance imaging was performed before and 3 months after injection to compare muscle cross-sectional areas. The symptoms of two patients improved and an increase of muscle cross-sectional area was observed. However, it is necessary to be prudent when employing intramuscular bupivacaine in oculomotor paresis treatment until there are more and larger studies.
