Elderly patient diagnosed with myasthenia gravis with recurrent failed weaning and prolonged apnea

Abstract

Myasthenia gravis (MG) is a chronic autoimmune neuromuscular disorder caused by the development of antibodies to nicotinic acetylcholine receptors. The disease characterized by variable muscle weakness worsening with exercise. Although most patients have neurological signs and symptoms, respiratory symptoms occur in the late stages of the disease. However, rarely, respiratory failure may be the first symptom in some undiagnosed patients. We report the case of an elderly patient who was admitted with respiratory failure and intubated and transferred to the internal medicine intensive care unit. Two days after intubation, when she was awake and met the extubation criteria, endotracheal tube was successfully removed. At this time, her vital signs were normal. However, next day, her arterial blood gas CO2 rose and he became drowsy, requiring re-intubation. This situation repeated on the fifth and 16th days of her hospitalization and prolonged apnea was observed after intubation with rocuronium. All other causes of failed extubation, such as sepsis and pneumonia, were ruled out. During follow-up, ptosis was detected in the right eye and acetylcholine receptor antibody was positive. On the 30th day of the follow-up, methylprednisolone 1mg/kg and pyridostigmine 240 mg/day was initiated. The patient, whose spontaneous respiration was sufficient, was extubated and taken to the neurology clinic for further examination and treatment.
