Syncope

Syncope (also called wrong axillary) is a temporary loss of consciousness caused by temporary ischemia and hypoxia of the brain. Syncope is different from coma. Coma loses consciousness for a long time and recovery is difficult. The difference between syncope and shock is the unconscious disturbance in early shock, and the signs of peripheral circulation failure are more obvious and persistent. Patients with syncope cannot be ignored and should be treated promptly. Syncope is a common clinical syndrome with the risk of disability or death. It is manifested by sudden muscle weakness, loss of postural muscle tension, inability to stand upright and loss of consciousness. Syncope has a certain incidence and may occur even in normal people. Syncope reported abroad can be seen in 3% of men and 3.5% of women, accounting for 3% of emergency department patients and 6% of hospitalized patients. Because the seizures are intermittent, there are many potential causes, and there is a lack of uniform diagnostic and treatment standards. Some syncope cases are difficult to diagnose and involve multiple departments. Therefore, it is important to understand the mechanism, clinical manifestations and diagnosis and treatment of syncope in detail. First, syncope must be distinguished from other neurological symptoms such as fainting, dizziness, falls, seizures, etc. Syncope refers to the weakness of the muscles and the feeling of being unable to stand upright, but the consciousness is still retained, so it is sometimes called "pre-syncope state". Dizziness is mainly a feeling of self or surrounding things spinning. A fall attack is a sudden loss of muscle tension in the lower limbs that causes a fall. It can immediately stand and continue walking. It is more common in transient vertebrobasilar ischemia. None of the above three have lost consciousness. Sometimes syncope is not easy to distinguish from seizures in epilepsy. The specific method is described in detail below. A syncope is almost always in an upright position, and patients usually have an uncomfortable feeling that they are about to faint. Then, dizziness and the feeling of shaking the floor or surrounding objects accompanied by mental confusion, yawning, dark spots in front of eyes, blurred vision, tinnitus, with or without nausea and vomiting, pale, and a lot of cold sweat. Some slow-onset cases allow patients time to protect from injury, while others are sudden and unpredictable.
