人工机械瓣膜功能障碍患者的术前急救护理

Preoperative emergency nursing in the patients with mechanical prosthetic valve dysfunction

目的探讨人工机械瓣膜功能障碍患者的术前急救护理要点。方法回顾性分析我院收治的5例瓣膜功能障碍患者的临床资料，总结术前的急救护理要点。结果本组4例患者经积极有效的救护，接受再次主动脉瓣膜置换术，康复出院。1例因病情危重，家属放弃治疗。结论人工机械瓣膜功能障碍会导致急性血流动力学紊乱致患者死亡，对其有效的处理为尽早行换瓣手术，而术前的严密监护，有针对性的急救护理非常关键，能为患者赢得手术时间，提高患者生存的机会。

Objective To explore the key points of preoperative emergency nursing in the patients with mechanical pros thetic valve dysfunction. Methods The clinical data from five patients with mechanical prosthetic valve dysfunction from March 2010 to November 2012 were retrospectively analyzed, and the key points of preoperative emergency nursing were summarized in the course of the disease. Results Four patients were recovered and discharged after they got the positive and effective rescue and accepted the valve replacement operation; one patient gave up further treatment because of serious condition. Conclusions The mechanical prosthetic valve dysfunction can lead to acute hemodynamic instability and eventually cause death of patients, and the valve replacement operation as the effective treatment should be carried out as early as possible. The preoperative intensive monitor and targeted emergency nursing can help patients to win the operative time and increase the chance of survival.
