肺病急性加重期常常伴有充血性心力衰竭,而心力衰竭又主要由于肺内感染、毛细血管壁充血、水肿,肺动脉压力急剧上升,诱发了右心衰竭。最关键的是以最为有效的抗生素治疗,积极控制感染。一般病人心功能常能得到改善,尿量增多,浮肿消退,不需使用强心药与利尿药。但病人病情较重或经治疗无效时可适当采取下列措施: 1.强心药肺心病由于缺氧及感染对洋地黄类药物耐受性很低,疗效较差,易引起中毒,这与处理一般心衰有所不同,但有下列指征仍可应用:①感染已被控制呼吸功能已改善,利尿剂不能取得良好疗效而反复浮肿的心力衰竭病人;②以右心功能衰竭为主而无明显急性感染的诱因者;③并发急性左心衰竭者。选用作用快、排泄快的强心制剂、剂量约为常规剂量的1/2～1/3,常以毒毛旋花子
Acute exacerbation of lung disease often accompanied by congestive heart failure, and heart failure and mainly due to pulmonary infection, capillary wall congestion, edema, pulmonary hypertension rose sharply, induced right heart failure. The most critical is the most effective antibiotic treatment, and actively control the infection. General patient heart function can often be improved, increased urine output, edema subsided, without the use of cardiac and diuretics drugs. However, patients with severe illness or treatment may be ineffective to take the following measures: 1. Cardiac pneumonia due to hypoxia and infection on digitalis drug is very low tolerance, efficacy is poor, easily lead to poisoning, which deal with General heart failure is different, but the following indications can still be applied: ① infection has been controlled respiratory function has been improved, diuretics can not get good results and repeated edema in patients with heart failure; ② right heart failure without Obvious incentive for acute infection; ③ complicated by acute left heart failure. Selection of fast acting, excretion of cardiac products, the dose is about 1/2 ~ 1/3 of the conventional dose, often toxin hair spinach
