When is the epidural haematoma, what are the common causes and clinical manifestations?

An epidural haematoma is the potential gap between the skull plate and the skull, usually due to severe head traumas, such as traffic accidents, falls or violent blows. This type of haematoma is closely related to a skull fracture, with about 90 per cent of the epidural haematoma associated with a skull fracture. The following are detailed:I. Causes1. Broken skullMost of the epidural haematoma is due to the fracture of the skull, which resulted in hemorrhage from the artery of the brain and its branches. For example, when a violent impact occurs on the side of the head, a fracture of the gill bone can easily cause a fracture of the artery in the brain. Because the artery moves close to the inner plate of the skull in the brain, the fractured end of the bone is prone to the puncture of the vein, and the blood accumulates in the outer gap of the hard-drive, creating haematoma.2. vascular damageIn addition to the membrane artery, a number of other amphibians, such as veins, can cause epidural haematoma. The haematoma caused by intravenous injuries may be relatively slow, but if not addressed in a timely manner, it can also cause serious damage to the brain tissue. For example, as a result of the damage to the upper vectoral beryllium, the blood accumulates out of the dural, as haematoma increases and oppresses the brain tissue.II. Clinical performance1. Awareness barriersThe typical pattern is post-injury with a “intermediate sobering period”. The injuries were likely to result in a short coma as a result of a concussion of the brain tissue during a head injury. The patient is then sober, and this period can last for several hours, and the patient can communicate, operate, etc. Then, as the haematosis increases, the brain tissue is oppressed and the patient falls into a coma. However, not all patients have an intermediate period of sobering, and some may remain unconscious after injuries, which is related to factors such as the speed at which haematoma is formed and the amount of haemorrhage.2. Symptoms of internal pressure increasePatients suffer from headaches, nausea and vomiting. Headaches are generally more severe, due to haematoma irritation to the dural membranes and increased intracranial pressure. The vomiting is often ejected because of the increased internal pressure that stimulates the vomiting centre. As the condition evolves, the patient may also have an oscillation of his/her nipple, which is one of the major signs of increased internal pressure, as can be seen in the vagueness of his/her nipple boundary and the rise of his/her head.3. Student changeWhen the osteoporosis side moves its eyes and nerves, pupils change. Early pupils may be reduced because of the neurological irritation. The pupils then spread out, reflecting light slowly or disappearing. This is a serious signal that haematoma has reached a high level of stress on brain tissue and nerves, requiring immediate treatment.4. Symptoms of the nervous systemDepending on the brain area of haematosis, the patient has different symptoms. If the haematoma oppresses the sports area, it leads to incapacitation or paralysis of the side limbs. For example, the presence of haematoma in the left hemisphere of the brain may cause physical activity disorders on the right side from mild to total inactivity. If language centres are oppressed, language barriers, such as speech loss, may prevent patients from expressing their thoughts normally or from understanding others ‘ words.If the patient suffers from a head trauma, the typical manifestation of a coma – sobering – is repeated, with more consideration given to epidural haematoma, timely consultation is required and diagnosis usually relies on head CT scans. The prognosis depends on the size of the haematoma, the rate of haemorrhage, the age of the patient and the overall state of health. Timely treatment can significantly improve the patient ‘ s prognosis, but may be poor if there are serious complications, such as encephalitis.
