患肺部疾病患者中约8%伴有咯血,其中10%～15%的病例发生威胁生命的大咯血。一次咯血量超过500ml,或24小时达2000ml者称之为大咯血。大咯血发生窒息者死亡率极高。出血速度是影响预后的重要因素,出血速度越快,危险性越大;肺功能差者病死率亦高。综合性治疗死亡率为22%～50%;手术治疗的存活率为80%以上。因此,救治大咯血病人,若已 About 8% of people suffering from lung disease have hemoptysis, and 10% to 15% of them have life-threatening hemoptysis. Once a hemoptysis volume of more than 500ml, or up to 2000ml for 24 hours were called massive hemoptysis. Severe hemoptysis occurs asphyxia death rate is very high. Bleeding speed is an important factor affecting the prognosis, the faster the bleeding rate, the greater the risk; poor lung function, mortality is also high. Comprehensive treatment of mortality was 22% to 50%; surgical treatment of survival rate of 80%. Therefore, the treatment of patients with hemoptysis, if already
