硝酸甘油静脉滴注抢救1例重症急性左心衰竭

Intravenous Drip of Nitroglycerin to Rescue 1 Patients with Severe Acute Left Heart Failure

急性心衰患多采用常规治疗,包括降压、强心、利尿、扩管等,虽然能起到抑制病情进展的作用,但往往达不到令人满意的程度,如何提升重症急性心衰患者治疗效果是许多临床学者研究的重点。本次研究收治的1例重症急性左心衰竭患者,就诊后积极开展诊治工作,在行常规降压、强心、利尿、扩管、抗感染治疗基础上加用硝酸甘油静脉滴注治疗,取得了较为显著的效果。左室舒张压力及容积增加、左房室负荷及房内压增高、肺静脉压升高以及体内诸多加压因子代偿性升高是急性左心衰竭患者的主要特征,急性期患者肺小动脉及周围小血管大多处于收缩或痉挛状态,因此主张使用血管扩张剂缓解患者血管收缩、痉挛状态。

Acute heart failure patients often use conventional treatment, including hypotension, cardiotonic, diuretic, dilatation and so on, although it can inhibit the progress of the disease, but often not to a satisfactory degree, how to improve the treatment effect of severe acute heart failure patients is the focus of many clinical scholars. In this study, 1 patients with severe acute left heart failure were treated, after seeing a doctor, actively carry out the diagnosis and treatment work, in the routine hypotension, cardiotonic, diuretic, dilatation, anti-infective treatment on the basis of intravenous drip of nitroglycerin treatment, achieved more significant results. Increased left ventricular diastolic pressure and volume, increased left atrioventricular load and intra-atrial pressure, elevated pulmonary venous pressure and compensatory elevation of many pressure factors in the body are the main characteristics of patients with acute left heart failure. Most of the pulmonary arterioles and peripheral small vessels in patients with acute phase are in a state of contraction or spasm. Therefore, vasodilators should be used to relieve the symptoms. Vasospasm and spasticity were resolved.
