How to treat myocardial infarction abroad

summary

Myocardial infarction is the death of myocardial cells caused by prolonged myocardial ischemia. On the basis of coronary artery disease, the blood supply of coronary artery is sharply reduced or interrupted, which makes the ischemic part of the myocardium severely ischemic and persistent lack of blood supply, resulting in cell death. The main clinical manifestations are persistent severe pain behind the sternum, fever, increased white blood cell count and serum markers of myocardial necrosis, and progressive changes in ECG. The main cause of myocardial infarction is coronary atherosclerosis. Its clinical manifestations are related to the location of infarction. I will tell you how to treat myocardial infarction abroad.

How to treat myocardial infarction abroad

First: patients should be absolutely bed rest before treatment, keep the environment quiet, eliminate adverse stimulation, routine oxygen inhalation, 3 to 4 liters per minute, take anti platelet agglutination drugs, such as aspirin is the routine medication before thrombolytic therapy. Take it once a day, 75 to 150 mg once a day after 3 days, maintain the dosage.

Second: pethidine intramuscular injection or morphine subcutaneous injection is the first choice to relieve the pain caused by myocardial infarction, but it should be noted that such drugs have the effect of inhibiting respiration. For patients with mild pain, intramuscular injection or oral administration of codeine or papaverine should be used to avoid long-term use to prevent addiction. Nitroglycerin or isosorbide nitrate sublingual administration can relieve angina pectoris, but blood pressure should be monitored.

Third: for drug treatment at the same time, as soon as possible to open blood vessels, the chance of saving the heart will increase. Myocardial reperfusion therapy can make the occluded coronary artery recanalized, myocardial reperfusion, myocardial necrosis may be able to survive. Thrombolytic therapy should be carried out immediately if other therapies are ineffective. Thrombolytic drugs such as urokinase, streptokinase, etc.

matters needing attention

For the treatment of patients with myocardial infarction, in addition to drug treatment to relieve pain, we should also pay attention to the treatment of accompanying symptoms. Lidocaine can relieve arrhythmia, quickly establish venous access, replenish fluid, expand blood volume, correct shock and acidosis. Anticoagulation therapy after thrombolytic therapy has a positive effect on preventing the expansion of infarct size and reinfarction. Patients' families should master the treatment of acute attack of myocardial infarction Method patients to maintain a peaceful state of mind, not mood ups and downs.
