Symptoms of brain stem injury

summary

Brain stem injury is one of the most harmful diseases. Brain stem injury can be divided into many types, including severe brain injury, primary and secondary brain injury. Brain stem injury can be divided into midbrain, pons, medulla oblongata and so on. Brain stem injury is a fatal disease. When patients find abnormal symptoms of the disease, they should do a good job of examination and treatment, So what are the symptoms of brain stem injury? Now let's talk about it.

Symptoms of brain stem injury

In patients with primary brain stem injury, unconsciousness often occurs immediately after injury. Mild patients can respond to pain stimulation, severe patients have deep unconsciousness and all reflexes disappear. If coma lasts for a long time, and there are few intermediate awake or intermediate improvement period, we should think of secondary brain stem injury caused by intracranial hematoma or other reasons.

The changes of pupil and eye movement, eye movement and pupil regulation function are managed by the brain nerves such as oculomotor, trochlear and abduction. Their nerve nuclei are located in the brain stem, which can change when the brain stem is injured. In the early stage of midbrain injury, the pupil on both sides was not equal in size, the pupil on the injured side was dilated, the reaction to light disappeared, and the eyeball tilted downward and outward; When both sides were injured, the pupil dilated and the eyeball was fixed. In pontine injury, there may be signs such as extremely narrowing of two pupils, disappearance of light reflex, introversion of two eyeballs, syntaxis or separation of two eyeballs.

Decortical ankylosis is one of the important manifestations of midbrain injury. The results show that there is a center at the level of vestibular nucleus to promote extensor contraction, and the red nucleus and its surrounding reticular structure are the center to inhibit extensor contraction. When they were cut off, there was decortical ankylosis. The results showed that the tension of extensors was increased, the two upper limbs were over extended and supinated, the lower limbs were over extended, and the head was tilted back, showing angle arch reverse tension. The mild injury may be paroxysmal, and the severe injury may be persistent.

matters needing attention

Eat a balanced diet, eat more fruits and vegetables and other high fiber food, eat more eggs, soybeans and other high protein food, pay attention to light diet, can carry out moderate exercise, avoid tobacco and alcohol, quit spicy, coffee and other stimulating food. Pepper, mustard, pepper, strong tea, coffee, cocoa and other foods or beverages can stimulate the gastric mucosa, cause congestion and aggravate inflammation, and should also be given up.
