本文应用钾、镁制剂治疗慢性肺心病难治性心衰并发低钾低镁血症46例,均取得满意效果.结合文献说明了低钾低镁对慢性肺心病难治性心衰的影响,洋地黄中毒、哮喘与低钾低镁明显相关.揭示:对慢性肺心病难治性心衰的患者,不仅要积极纠正低钾低镁血症,而且常规治疗上应用镁剂能增加心肌的舒缩功能,缓解支气管平滑肌痉挛,这种对循环和气道的双重扩张作用,时改善心肌收缩状态,减轻心脏前后负荷,扩张肺小动脉,降低肺动脉压力,调整肺内通气,血流比例失调,增强利尿作用,均具有较显著的治疗作用。体会:慢性肺心病难治性心衰并发低血钾者,均并发低血镁,在迅速补钾同时必须补镁.补镁可显效,慢性肺心病难治性心衰出现洋地黄中毒引起的心律失常和顽固性哮喘,顽固性低血钾、镁剂不失为治疗的首选药物;镁为治疗慢性肺心病难治性心衰提供了一种新的途径和理论依据,可作为常规治疗的一种措施。
In this paper, the application of potassium and magnesium preparations of chronic cor pulmonale refractory heart failure complicated by hypokalemia and hypomagnesemia in 46 cases, have achieved satisfactory results combined with the literature describes the low potassium and low magnesium refractory heart failure of chronic pulmonary heart disease, Digitalis poisoning, asthma and low potassium low magnesium significantly.Related: chronic heart failure refractory heart failure patients, not only to correct the hypokalemia and hypomagnesemia, and conventional treatment of magnesium can increase myocardial Shu Contraction function, relieve bronchial smooth muscle spasm, this dual role in the expansion of the circulation and airway, improve myocardial contractility, reduce cardiac before and after the load, expansion of pulmonary arterioles, reduce pulmonary artery pressure, adjust the lung ventilation, blood flow imbalance, enhanced Diuretic, have a more significant therapeutic effect. Experience: Refractory heart failure complicated by chronic hypokalemia in patients with chronic hypokalemia, are complicated by hypomagnesemia, in the rapid potassium supplement must be supplemented with magnesium. Magnesium supplementation can be effective, refractory chronic heart disease caused by digitalis poisoning Arrhythmia and intractable asthma, intractable hypokalemia, magnesium is the treatment of choice medicine; magnesium for the treatment of refractory heart failure of chronic pulmonary heart disease provides a new way and theoretical basis, can be used as a routine treatment Measures.
