How many days do I need to be observed for a blow to the head?

Generally, within 24 hours after impact, it can be determined whether there is obvious injury, internal bleeding, congestion, edema, etc., and if some symptoms of brain ** do not appear within three days, there should be no problem.

Brain ** can cause a certain degree of confusion and headache in patients.

Unusual drowsiness, with most people fully recovering after hours or days. Some patients may experience vertigo.

Attention disorders, amnesia, depression, apathy, and anxiety.

Severe cerebral ** generally** bed rest for 1 2 weeks, pay attention to reduce mental work, and give sedation, analgesics, and intravenous 50% glucose.

Yes**; For a small number of patients with severe headache, but in the process of ** observation, it is necessary to be alert to the occurrence of intracranial hematoma. Seek prompt medical attention.

Conventional wisdom holds that the brain is only the central nervous system.

Temporary dysfunction with no visible organic damage. But in recent years, studies have found that the mitochondria of neurons at the site of force.

axonal swelling, interstitial edema; Acetylcholine in cerebrospinal fluid.

and elevated potassium concentrations, disorders of the enzyme system that affect axon conduction or brain tissue metabolism. Clinical data also confirmed that half of the brainstem auditory evoked potentials in the brainstem of the brain** patients showed organic damage. Some scholars have suggested that the brain may be the lightest form of diffuse axonal damage.

I was hit by the iron bar of the door at a distance of 10 centimeters to the side of the head, and I don't feel uncomfortable at the moment, but the part of the hit is wrapped up, and it hurts a little.

Hello this friend, my situation is similar to you, now I have been hit for three months, and it is not good, there is no problem with the CT examination and the magnetic resonance examination later, I would like to ask you what you did at that time**, how long**, I hope to get your answer, thank you.

If the point of impact is the temple of the head (as long as it is a fatal part of the human body, the impact will definitely be life-threatening), it will definitely be killed.

If a person's head hits a wall and causes a brain contusion and laceration, it will damage the life center of the brain stem, and he will die. Otherwise, it will only cause the general brain **, and it will not die. It is related to the force and angle of hitting the wall, or the part of the impact.

History has not yet determined who was killed, generally it is difficult to die, the strength and speed can not be small, and it will be very uncomfortable if you can't die after hitting the wall.

Summary. Not all heads are struck with death.

Not all heads are struck with death.

It should be observed first.

Hello, head trauma to the human body.

It mainly lies in the damage to the cranial nerve tissue.

Mild cerebral contusion and laceration.

Maybe it doesn't hurt.

Severe cases include cerebral hemorrhage or cerebral herniation.

The solid skull, like a natural helmet, protects our brain, but despite this, the brain is still susceptible to various traumas. Traumatic brain injury is the common cause of death and disability in people under 50 years of age, and it is also the second leading cause of death in men under 35 years of age (gunshot wounds are the first). About half of people with severe traumatic brain injury do not survive.

Even if the skull is not penetrated, the brain is inevitably damaged during head trauma. Sudden acceleration of the head, as can cause brain damage as a slam on the head; Rapid head strikes against immobile hard objects or sudden deceleration are also common causes of traumatic brain injury. Brain tissue on the side of the impact or in the opposite direction is highly susceptible to injury when it collides with a hard, bulging skull.

Acceleration-deceleration injuries are sometimes referred to as contralateral impact injuries.

Severe traumatic brain injuries can stretch, twist or tear the nerves, blood vessels and other tissues in the brain. Nerve pathways are disrupted, or hemorrhage or edema may occur. Intracranial hemorrhage and cerebral edema enlarge the contents of the cranial cavity, but the cranial cavity itself cannot expand commensurately, resulting in increased intracranial pressure and further destruction of brain tissue.

Increased intracranial pressure pushes the brain downward, forcing upper brain tissue and brainstem into the associated orifice, a condition called herniation. The cerebellum and brainstem may be displaced from the foramen at the base of the skull to the spinal cord. Because the brainstem has important functions to maintain breathing and heartbeat, brain herniation is often fatal.

Older people are particularly likely to cause bleeding around the brain (subdural hemorrhage) after a head injury, and people who take anticoagulant drugs to prevent blood clots are also at high risk of subdural hemorrhage after trauma.

Brain damage often causes varying degrees of permanent dysfunction. It depends on whether the damage is in a specific area of brain tissue (focal) or widespread (diffuse). Brain damage in different areas can cause different symptoms, and these specific focal symptoms help doctors identify the location of the injury.

Focal symptoms include motor, sensory, speech, visual, and auditory abnormalities. Diffuse brain damage, on the other hand, often interferes with memory, sleep, or causes confusion and coma.
