One day in November 2008, she came to the Thoracic Surgery Department of Southern Hospital because of weakness in her hands and feet, and was diagnosed to have myasthenia gravis. In December 2008, after thorough preparation, we performed thymoma resection for this patient, the operation went well and the recovery was satisfactory in the days after the operation, but about a week after the operation, the patient developed respiratory weakness and continued to worsen, which is a common and serious postoperative complication for patients with myasthenia gravis –myasthenia crisis! We reintubated her with a ventilator to help her breathe, and since then, she has been battling with the disease for six months. During this period, her condition fluctuated and she was basically unable to get out of bed and had to rely on the ventilator to assist her breathing, and she also developed lung infection, pleural effusion and other related complications. In early May 2009, after long efforts and waiting, her condition miraculously started to improve and she was able to get out of bed after a week, we encouraged her to be more active, encouraged her to go out of the ward to see the grass, the green trees and the long-lost sunshine. Soon, the patient was able to completely disconnect from the ventilator and breathe on her own, and was discharged from the hospital in June 2009. When a beautiful lady appeared in front of us in September 2009, we almost didn’t recognize her. We were very happy to see her recovering so well, and we admired her family’s persistence and cooperation all the time. In myasthenia gravis, simply speaking, the most life-threatening thing is that the patient has no strength to breathe, and the CO2 in the body gradually increases, the patient’s breathing will become weaker and weaker, which will eventually lead to death. This patient’s persistent myasthenia crisis is rare in clinical practice, but after nearly 7 months of hard work, we have worked with the patient and family to make life come alive again, which is the greatest reward and encouragement for us!
