What are the treatments for cor pulmonale

The issue of medication for the treatment of cor pulmonale cannot be ignored. These cor pulmonale can pose a great danger to human health. Drug treatment includes some diuretics and cardiotonic agents. However, when using any medication, you should consult a professional doctor and not take the medication blindly.

1. Diuretics: Eliminate edema by inhibiting renal sodium and water reabsorption, reduce circulating blood volume, and reduce right heart preload. The principle is to use small doses and combined use of potassium-excreting and potassium-sparing diuretics, with a short course of treatment and intermittent medication. Generally, hydrochlorothiazide (hydrochlorothiazide) 25 mg, 1 to 3 times/day, combined with spironolactone 40 mg, 1 to 2 times/day can be used. Pay attention to potassium supplementation during use.

2. Cardiotonic agent: The evaluation of digitalis in treating heart failure caused by cor pulmonale is mixed. This is mainly because the lack of oxygen in cor pulmonale increases the sensitivity to digitalis, which can easily lead to poisoning, such as arrhythmia and even sudden death. Therefore, caution should be exercised when using digitalis in patients with cor pulmonale and heart failure. However, it is inappropriate to completely oppose the use of digitalis in patients with cor pulmonale and heart failure. The use of digitalis should still be considered in the following situations: A. Patients whose infection has been controlled, respiratory function has improved, and diuretic treatment has failed to improve right heart function; B. Patients with supraventricular rapid arrhythmias, such as supraventricular tachycardia and atrial fibrillation (ventricular rate > 100 beats/min); C. Patients with right heart failure as the main manifestation and no obvious acute infection; D. Patients with acute left heart failure. The principle of medication is to use a small dose (1/2 to 1/3 of the regular dose), fast-acting, and fast-excreted cardiotonic agent. Commonly used drugs are 0.2 to 0.4 mg of digoxin or 0.125 to 0.25 mg of sedigrin K added to 20 ml of glucose solution and slowly injected intravenously. Attention should be paid to correcting hypoxia and hypokalemia, and the therapeutic effect should not be observed based on the heart rate. Because hypoxia and hypokalemia can cause an increased heart rate.

3. Treatment of arrhythmia: General arrhythmia can disappear on its own by controlling respiratory tract infection, correcting hypoxia, carbon dioxide retention, acid-base imbalance and electrolyte disorder. If it persists, drugs can be selected according to the type of arrhythmia.

4. Nursing: Patients with cor pulmonale often suffer from multifunctional organ failure during the acute exacerbation period. Comprehensive and correct assessment of the condition, formulation of detailed nursing measures, and correct and effective implementation are the key to successful rescue. It is very important to strengthen psychological care, improve patients' confidence in treatment, and cooperate with medical treatment.
