Myasthenia gravis: brief guide to diagnosis and management.
Physicians should consider the possibility of myasthenia gravis in patients complaining of fluctuating muscle weakness and easy fatigability. The disorder may occur in either sex at any age. Repeated measurements of multiple muscle groups and functions to include baseline strength and response to a control as well as anticholinesterase drugs are desirable in reaching a diagnosis. Appropriate doses of anticholinesterase medication reduce weakness and fatigability in most patients. Selected patients may benefit from thymectomy. Patients in crisis failing to respond to anticholinesterase drugs, having difficulty maintaining a patent airway or adequate respiratory exchange are best managed by prompt tracheostomy using a cuffed tube, with adequate tracheobronchial toilet and mechanical respiratory assistance.
