What are the causes of transient syncope?

summary

Transient syncope, also known as simple, neurovascular syncope, is a sudden and transient loss of consciousness, which can be accompanied by systemic symptoms, such as dizziness, dizziness, tinnitus, pale complexion and cold sweat. The common situation is orthostatic hypotension; Micturition syncope and continuous hot water bath for a long time. What are the causes of transient syncope? Let's talk about it

What are the causes of transient syncope?

It is mainly caused by transient cerebral ischemia and hypoxia. It is often caused by some strong stimulation, such as fear, severe pain, death of relatives, frustration, fasting overwork or operation, bleeding, blood, injection, trauma, air pollution and sultry, which can cause reflex peripheral vasodilation, decrease of cardiac output and sudden decrease of blood pressure, which can lead to transient syncope.

Because of some strong stimulation, such as fear, severe pain, death of relatives, frustration, fasting overwork or surgery, bleeding, blood, injection, trauma, air pollution and sultry, it can cause reflexive peripheral vasodilation, decrease of cardiac output and sudden decrease of blood pressure, which can lead to transient syncope

Due to the increase of vagus nerve excitability and the decrease of sympathetic nerve excitability, the heart rate slows down, the peripheral blood volume decreases, and the cardiac output decreases. When the patient is in the upright position, the brain lacks sufficient blood supply, resulting in a sudden loss of consciousness.

matters needing attention

When the patient faints and falls, he should lie flat and untie his collar quickly. Pay attention to keep the airway unobstructed. When there is too much sputum, he should suck sputum to avoid blocking the airway. When the patient begins to wake up, he should not sit up in a hurry, let alone stand up. He should lie flat for a few minutes and then sit up slowly to avoid recurrence of fainting.
