dangerous moments of high blood pressure

Core clew: patients with high blood pressure because long-term blood pressure is bigger, the blood vessels in the spasticity, so that blood vessel elasticity decreased, and the brittleness increases, if at this time due to some reason contributing to increased blood pressure suddenly, is easy to cerebral hemorrhage, cerebral vascular rupture and causing this for patients with high blood pressure, is undoubtedly the most fatal blow. Therefore, patients with hypertension should try to avoid a sudden rise in blood pressure, especially under the following circumstances, should be more cautious. Due to the long-term pressure on blood vessels, blood vessels are in a spasm state in patients with hypertension, resulting in decreased vascular elasticity and increased brittleness. If blood pressure rises suddenly due to some reason at this time, it is easy to cause cerebral vascular rupture and cerebral hemorrhage, which is undoubtedly the most fatal blow for patients with hypertension.

Seven tips to correctly identify intracranial hypertension

The three typical symptoms of intracranial hypertension are headache, vomiting, and papilloma. As a nurse in the department of neurology, Today I want to take you to understand what intracranial hypertension is and how to deal with such family members and patients.

1. Headache is the most common symptom of intracranial hypertension, the higher the intracranial pressure, the more obvious the headache, more diffuse blunt pain, pain is good in the morning, often persistent or paroxetine aggravation. Any cause of increased intracranial pressure, such as cough, defecation, can aggravate the pain. Vomiting or excessive ventilation may relieve the headache. Acute intracranial pressure increased headache severe, fidgeting, often accompanied by projectile vomiting.


2. Vomiting is generally unrelated to diet, with or without nausea before vomiting, and often eruptive, accompanied by severe headache and dizziness. Vomiting symptoms are also severe when the headache is severe.

3. Visual impairment, the performance for a sexual amaurosis, gradually develop to vision loss or even blindness. Fundus examination showed papillary edema, venous dilatation, and bleeding. Diplopia may be present when compression and papilloma may be ignored when acute intracranial hypertension is present.

4. Disturbance of consciousness, irritability, indifference, dullness, lethargy, and even coma.

5. Seizures or ankylosing spondylitis.

6. Vital signs change, blood pressure rises, the pulse is slow and heavy, breathing is slow and deep, which are the three main signs in Cushing. The pulse of severe intracranial hypertension can be less than 50 times per minute, breathing about l0 times per minute, systolic blood pressure up to 24kPa (l80mmHg) to stop, which is the foreboding sign of a cerebral hernia.

7. Manifestations of cerebral hernia include increased intracranial pressure to a certain extent, displacement of part of brain tissue, extrusion of the dural fissure or foramen magnum and compression of nearby nerves, blood vessels, and brain stem, resulting in a series of symptoms and signs. There are two common types of cerebral hernia.

(1) Tentorial hernia (temporal lobe sulcus hernia), ipsilateral oculomotor nerve palsy, manifested as saggy eyes, dilated pupils, dull or absent light reflex, varying degrees of consciousness disorder, changes in vital signs, contralateral limb paralysis, and pathological reflex.

(2) Foramen magnum hernia (cerebellar tonsillar hernia), pain in the posterior neck and occipital, stiff cervical muscles, forced cephalic drowsiness, disturbance of consciousness, large or incontinence of urine or even deep coma, dilated bilateral pupils, slow or absent reflex to light, a deep slow or sudden stop of breathing.
