目的提高对慢性肺源性心脏病(以下简称肺心病)并低钠血症、慢性呼吸衰竭(以下简称呼衰)的认识,并及时恰当处理。方法回顾分析了慢性肺心病并低钠血症77例(不含呼衰病例);呼吸衰竭32例,32例呼衰中低钠血症5例,无低钠血症27例;在不含呼衰病例中,低钠血症分为轻、中、重,分别将它们比较,分析它们对预后的影响和治疗。结果低钠血症组中19例死亡,死亡率24.7%,而对照组死亡率为8%,两组比较P<0.01;在血钠正常病例中,呼衰组死亡10例,死亡率37%,而对照组为8%,两组比较P<0.01;在低钠血症病例中呼衰组死亡4例,死亡率为80%,而对照组为24.7%,两组比较P<0.01。结论肺心病合并低钠血症影响疾病的预后,血钠降低越低死亡率越高,死亡率与低血钠的程度负相关。肺心病合并呼衰也是影响疾病预后的主要因素,两者合并存在,严重影响疾病的预后。
Objective To raise awareness of chronic pulmonary heart disease (hereinafter referred to as pulmonary heart disease) and hyponatremia, chronic respiratory failure (hereinafter referred to as respiratory failure) and timely and appropriate treatment. Methods A retrospective analysis of 77 cases of chronic pulmonary heart disease with hyponatremia (excluding respiratory failure cases); respiratory failure in 32 cases, 32 cases of respiratory failure in 5 cases of hyponatremia, no hyponatremia in 27 cases; In respiratory failure cases, hyponatremia is divided into mild, moderate and severe, respectively, to compare them, analyze their prognosis and treatment. Results In the group of hyponatremia, 19 patients died and the mortality rate was 24.7%, while that of the control group was 8% (P <0.01). In the normal serum sodium, 10 patients died of respiratory failure and the mortality rate was 37% , Compared with 8% in the control group (P <0.01). In hyponatremia cases, 4 patients died of respiratory failure, the mortality rate was 80%, while the control group was 24.7%, P <0.01. Conclusions Pulmonary heart disease with hyponatremia affects the prognosis of the disease. The lower the hyponatremia is, the higher the mortality is. The mortality is negatively correlated with the hyponatremia. Pulmonary heart disease combined with respiratory failure is also a major factor affecting the prognosis of the disease, the two merged, seriously affecting the prognosis of the disease.
