Closed traumatic brain injury

Introduction to closed brain injury Closed brain damage is mostly caused by traffic accidents, accidents such as falls, falls, and birth injuries. Light closed brain injury is mainly based on bed rest and general treatment. It usually takes 1 to 2 weeks to stay in bed. Pay attention to the observation of vital signs, consciousness and pupil changes. Ordinary diet, most patients can work normally after several weeks. The mechanism of closed brain injury is complicated. Most of the brain injury is often caused by several mechanisms and many factors. The main injury factors are two: 1. The brain damage caused by the deformation of the skull; Brain damage caused by linear or rotational movement of brain tissue in the cranial cavity. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific people Mode of infection: non-infectious Complications: intracranial hypertension syndrome multiple lung infections

Causes of closed brain injury

Causes of the disease: The mechanism of closed brain injury is more complicated. Most of the brain injury is often caused by several mechanisms and many factors. The main causes of injury are: (1) due to deformation of the skull, the brain is caused by the fracture. Injury; (2) Brain damage caused by linear or rotational movement of brain tissue in the cranial cavity.

Direct damage (50%):

(1) Accelerated damage: a brain injury caused by a moving object hitting a head at rest, such as a stick or stone injury.

(2) Deceleration damage: the moving head hits a stationary object and causes injury, such as falling and falling.

(3) crush injury: that is, two external forces in different directions act on the head at the same time, causing deformation and injury of the skull.

Indirect damage (30%):

(1) Transmitted injury: If the ground is hit by the buttocks or both feet when falling, the external force is transmitted along the spine to the base of the skull.

(2) whip injury: This damage often occurs at the junction of the skull and neck.

(3) Brain damage caused by chest crush injury: When the chest is severely squeezed, the sudden increase in intrathoracic pressure is transmitted to the brain along the jugular vein.

Closed brain injury prevention

The disease is a traumatic disease, no preventive measures, pay attention to safety, and avoid trauma.

Closed brain trauma complications Complications Multiple intrapulmonary infections of intracranial hypertension syndrome

1. Easy to merge with intracranial hematoma.

2. Long-term bed rest leads to lung and urinary tract infections, as well as acne.

Closed brain trauma symptoms Common symptoms Consciousness disorder Pupil abnormal respiratory abnormality Shock exercise injury Increased intracranial pressure episodes

1. Disorder of consciousness: Degree and change are important aspects of judging a injury.

2. Scalp injury, ear and nose bleeding and exudate.

3. Changes in vital signs (breathing, pulse, blood pressure and body temperature).

4. Increased intracranial pressure.

5. Impaired medullary function.

6. Shock.

7. Pupil size, shape and response to light changes.

8. Movement and reflection changes.

Examination of closed brain injury

1. Skull X-ray film: As long as the condition allows, routine examination should be done, according to the positive, lateral position or special position.

2. Lumbar puncture: to understand the changes in cerebrospinal fluid pressure and composition.

3. Ultrasound examination: On-screen hematoma can be displaced by the midline wave to determine the hematoma fixed side, but no displacement, can not rule out hematoma.

4. Cerebral angiography: The accuracy of diagnosis of intracranial hematoma is high.

5. CT and magnetic resonance examination are also important for the diagnosis of brain injury.

Diagnosis and diagnosis of closed brain injury

Should be differentiated from open brain damage:

Open brain injury: The brain injury associated with the brain tissue after injury is called open brain injury. Open brain damage is divided into two types: firearm injury and non-firearm injury. Pathological changes are roughly divided into three phases: acute phase, inflammatory reaction phase and complication phase.
