一例重症肌无力脱机困难患者的个案护理

Case Nursing of a Patient with Difficulty in Weaning off the Ventilator Due to Myasthenia Gravis

摘要: 目的：分析重症肌无力患者呼吸机脱机困难的临床原因，探讨针对性的护理干预措施及脱机成功的护理要点，为临床此类患者的护理提供实践参考。方法：对本院创伤急救重症监护室收治的1例重症肌无力脱机困难患者的临床资料进行回顾性分析，结合患者脱机困难的核心原因，实施病情精准监测、阶梯式呼吸肌训练、个体化脱机方案、多维度营养支持、心理干预及并发症防控等综合性护理措施，观察患者的脱机效果及康复转归。结果：该患者因呼吸肌肌力低下、呼吸肌废用性萎缩、心理焦虑及营养失衡等多重因素导致脱机困难，经上述针对性护理干预后，呼吸肌功能逐步恢复，脱机耐受度显著提升，最终顺利脱离呼吸机，未发生相关严重并发症，康复出院。结论：重症肌无力脱机困难的发生与呼吸肌功能、营养状态、心理因素等密切相关，针对脱机困难的核心诱因制定并实施个体化、阶梯式的综合性护理方案，是改善患者呼吸肌功能、提高脱机成功率的关键。

Abstract: Objective: To analyze the clinical causes of difficulty in weaning off the ventilator in patients with myasthenia gravis, explore the targeted nursing intervention measures and key nursing points for successful weaning, and provide practical reference for the clinical nursing of such patients. Methods: The clinical data of 1 patient with myasthenia gravis and difficulty in weaning off the ventilator admitted to the Trauma Emergency Intensive Care Unit of our hospital were retrospectively analyzed. Combined with the core causes of the patient’s difficulty in weaning off the ventilator, comprehensive nursing measures such as accurate disease monitoring, stepwise respiratory muscle training, individualized weaning plan, multi-dimensional nutritional support, psychological intervention and complication prevention and control were implemented to observe the weaning effect and rehabilitation outcome of the patient. Results: The patient had difficulty in weaning off the ventilator due to multiple factors such as low respiratory muscle strength, disuse atrophy of respiratory muscles, psychological anxiety and nutritional imbalance. After the above targeted nursing interventions, the respiratory muscle function recovered gradually, the tolerance to weaning off the ventilator improved significantly, and the patient finally weaned off the ventilator smoothly without serious related complications and recovered and discharged from hospital. Conclusion: The occurrence of difficulty in weaning off the ventilator in myasthenia gravis is closely related to respiratory muscle function, nutritional status, psychological factors and so on. Formulating and implementing an individualized and stepwise comprehensive nursing plan according to the core inducements of difficulty in weaning off the ventilator is the key to improving the patient’s respiratory muscle function and increasing the success rate of weaning off the ventilator.
