What are the causes of loss of consciousness?

summary

According to psychology, when patients lose consciousness, they have no spontaneous movement and do not respond to any stimulation. At this time, many reflexes, such as swallowing, defense, and even pupil response to light, disappear and lead to pathological reflexes. What are the causes of loss of consciousness? Next, I'd like to share my views with you.

What are the causes of loss of consciousness?

First: cerebrovascular disease: cerebral hemorrhage, cerebral infarction, transient ischemic attack, etc; Intracranial space occupying lesions: primary or metastatic intracranial tumor, brain abscess, brain granuloma, brain parasitic cyst, etc;

Second: craniocerebral trauma: brain contusion and laceration, intracranial hematoma, etc. Intracranial infectious diseases: all kinds of encephalitis, meningitis, arachnoiditis, ependritis, intracranial venous sinus infection, etc;

Third: the factors causing loss of consciousness also appear in many occasions, such as an operation with a high risk coefficient. The patient loses consciousness due to excessive blood loss or cardiac arrest. Similarly, if the doctor implements general anesthesia for the patient, the patient will also enter the state of loss of consciousness, but this is reversible.

matters needing attention

First of all, loss of consciousness, breathing, should let the patient Fu lying position, head back. In addition, when consciousness and breathing disappear, do not rush to artificial respiration. Because if the respiratory tract is blocked, even if artificial respiration is carried out, the air can not enter the lung, and artificial respiration is ineffective. In short, let the patient lie on his back at this time, put his hand behind the neck of the patient, press his forehead with the other hand (preferably with his right hand), pull back as far as possible, and make his head lean back for a while.
