2 months of baby brain injury symptoms?
summary
After craniocerebral injury, due to the different injury mechanism, injury site, injury severity, treatment time and other factors, the clinical manifestations are quite different. 2 months of baby brain injury symptoms? Let's talk about it.
2 months of baby brain injury symptoms?
（1） Disturbance of consciousness disturbance of consciousness is the most common symptom of patients with craniocerebral injury. The disturbance of consciousness immediately after injury is usually called primary disturbance of consciousness. If the patient has a period of waking up after injury, or after the primary disturbance of consciousness, the consciousness has improved for a time, and the condition has deteriorated again, and the disturbance of consciousness has aggravated, it is called secondary disturbance of consciousness. Primary disturbance of consciousness is usually caused by primary brain injury. Its pathophysiological mechanism is extensive cortical injury and diffuse axonal injury.
（2） Headache, headache and vomiting headache are commonly seen in all patients with brain injury, which can be caused by scalp or skull injury, intracranial hemorrhage and elevated intracranial pressure. Headache can be limited, usually seen in the site of external force, is caused by local tissue damage and its secondary inflammatory reaction; It can also be diffuse, often due to brain tissue damage or increased intracranial pressure. There is no certain relationship between headache and the severity of the disease. The patient complained of headache, but the location of the pain is superficial and limited, and the consciousness is clear. There is no obvious abnormality on CT, which is usually caused by extracranial tissue trauma. In addition to symptomatic analgesic treatment, there is no need for special treatment. If the patient has severe head pain, and gradually aggravated, accompanied by repeated vomiting, we should be highly alert to the occurrence of intracranial hematoma. Early postoperative vomiting can be caused by vagal or vestibular structure injury, but the increase of intracranial pressure is the main cause of headache in patients with craniocerebral injury. Recurrent ejection vomiting is a characteristic manifestation of intracranial hypertension.
（3） The pupil was innervated by parasympathetic branch and sympathetic nerve of oculomotor nerve. One side pupil dilated immediately after injury, light reaction disappeared, and the patient was conscious, which may be the primary injury of oculomotor nerve caused by skull base fracture. If the bilateral pupils are not equal in size, one pupil is narrowed, the light response is sensitive, and the ipsilateral face is flushed without sweat, and the eye fission is small (Horner syndrome), after excluding the possibility of cervical sympathetic nerve damage, we should consider whether there is focal brain stem injury. Such as bilateral pupil narrowing, light reaction disappeared, accompanied by bilateral pyramidal tract sign and central hyperthermia and other vital signs disorder symptoms, it means that the brain stem damage range is wide, the condition is critical. If headache and vomiting worsen after injury, consciousness disorder deepens gradually, accompanied by pupil dilation on one side, light reaction is slow or disappear, intracranial hematoma and tentorial notch hernia should be considered. If bilateral pupil dilation, light reaction disappeared, it belongs to the late stage of cerebral hernia. Generally speaking, when the patient is awake, the bilateral pupil expands and shrinks equally, but the light response is normal, and there is no pathological significance.
matters needing attention
It is closely related to the severity of the disease, the site of injury and timely treatment. The prognosis of patients with severe complications is dangerous, and the prognosis of patients with severe craniocerebral injury is affected by the sequelae.
