ABSTRACT

INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative condition producing symptoms of varying severity depending on the extent and progression of the disease pathology most importantly respiratory insufficiency and pulmonary complications. Myasthenia gravis (MG) on the other hand is an autoimmune condition due to the pathology involving failure of neuromuscular transmission causing muscle weakness exacerbated by activity and involvement of the respiratory muscles leading to respiratory failure. Overlap syndrome is a condition wherein both motor neuron disease (MND) and MG are present in the same patient. The safety of using muscle-relaxing agents in patients with MG undergoing major surgical procedures has so far been assessed as insufficient. There have been many concerns regarding anesthetic management in relation to complications with respiratory function in patients with ALS, with regional anesthesia being considered slightly safer.

CASE REPORT: An 81-year-old female presented with a closed injury to her left hip, and she was diagnosed to have a left neck of femur fracture. She was also a known case of bulbar MND with an overlap syndrome of MG. She was hypertensive and controlled with regular medication. She was planned for a left hip bipolar arthroplasty. Anesthetic requirements and management of these patients require a high degree of expertise and anesthesia in patients undergoing surgery is prone to more complications and mortality. In addition, as the patient had an overlap of both MG and MND, more meticulous assessment and management strategies were necessary.

CONCLUSION: The importance and purpose of this study are to highlight a case of overlap syndrome of MND and MG patients who sustained a left neck femur fracture and underwent bipolar arthroplasty highlighting the anesthetic considerations in the patient for the procedure. We concluded that the choice of mode of anesthesia needs to be individualized based on each patient's requirements after careful analysis of the risk-benefit ratio of general versus regional. Regional anesthesia was successfully administered for this patient.
