Edrophonium is available in multiple-dose or singledose 10-mg/ml ampules. An accessible vein is foimd on one of the patient s arms, and a butterfly infusion set with a 27-gauge needle is attached to a 1-ml tuberculin syringe containing 10 mg edrophonium solution. Initially, 2 mg (0.2 ml) edrophonium is injected intravenously. A saline flush may follow this injection to confirm appropriate dose administration. If after 1 or 2 minutes definite improvement in ptosis or ocular misalignment occurs, the test is considered positive and no further edrophonium injection is necessary. If no definite improvement occurs, however, another 3 mg (0.3 ml) edrophonium is injected and the patient is again observed.
