Continuous neostigmine infusion in post-thymectomy juvenile myasthenic crisis.

A 10-year-old boy with myasthenia gravis had severe post-thymectomy myasthenic crisis necessitating reintroduction of mechanical ventilation on the 5th day after thymectomy. He did not respond to therapy with oral pyridostigmine, corticosteroids, or high-dose intravenous immunoglobulin. Finally, in addition to the usual supportive care, he was treated successfully with continuous intravenous infusion of neostigmine. Continuous infusion of neostigmine was used for the first time in post-thymectomy myasthenic crisis in a child to the best of our knowledge.
