The wound no longer bleeds during surgery
Introduction
Introduction Wounds no longer bleed during surgery are common in sudden death coronary heart disease. Sudden-type coronary heart disease refers to a person who has no history of heart disease or only mild heart disease. The condition is basically stable. There is no obvious external cause, non-trauma or self-injury. The heart loses effective contraction due to heart failure or mechanical failure. death. Among them, the wound is no longer bleeding during surgery is a symptom of its symptoms. The pathological features were more than one coronary artery >75% stenosis, of which at least one vessel had >75% stenosis accounted for 94%, acute coronary occlusion was 58%, and healed myocardial infarction was 44%, acute myocardial infarction Accounted for 27%.
Cause
Cause
Extensive coronary artery disease is the main pathology of sudden death of coronary heart disease, and thrombosis in the coronary arteries and coronary vasospasm further promote the decline of myocardial infarction, thereby inducing ventricular fibrillation and cardiac arrest.

1. Patients with a history of coronary heart disease and ventricular fibrillation.
2. Unstable angina pectoris frequent with ST segment depression > 2mm.
3. Organic heart disease ventricular enlargement, cardiac dysfunction accompanied by syncope.
4. Organic heart disease with low potassium, low magnesium.
5. Changes in environmental factors such as excessive alcohol and tobacco, overwork, emotional agitation, sudden stress, etc. In these cases, myocardial ischemia is aggravated, catecholamine release is increased, and the threshold of ventricular fibrillation is lowered to induce sudden death. For such patients, active preventive and therapeutic measures should be taken. For those who have the following results, they should also be considered as highly dangerous and should be treated promptly.
Diagnosis
Differential diagnosis
Differential diagnosis of wound no longer bleeding during surgery:
1, acute myocardial infarction: acute myocardial infarction refers to coronary artery acute occlusion blood flow interruption, caused by regional myocardial ischemic necrosis, clinical manifestations may have persistent post-sternal pain shock, arrhythmia and heart failure, and serum Increased myocardial enzymes and changes in electrocardiogram.
2, acute pericarditis: pericarditis (pericarditis) is the most common pericardial lesions, can be caused by a variety of pathogenic factors, often part of the systemic disease, or spread from adjacent tissue lesions. Pericarditis can occur simultaneously with inflammation of other structures of the heart, such as the myocardium or endocardium, or it can exist alone. Pericarditis can be divided into acute and chronic, the former is often accompanied by pericardial effusion, the latter often causes pericardial constriction. Acute pericarditis is an acute inflammation of the visceral and parietal layers of the pericardium. It can be combined with myocarditis and endocarditis, or it can be the only heart lesion.
3, acute myocarditis (acute myocarditis) is a myocardial injury disease, often occurs in rheumatic fever or secondary to certain infectious diseases such as diphtheria, sepsis, pneumonia, scarlet fever and typhoid.
