Intramuscular Bupivacaine Injection for the Treatment of Oculomotor Paresis.
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.
