Nursing care of patients with increased intracranial pressure and cerebral herniation
increased intracranial pressure
Definition: An increase in the pressure exerted by the contents of the cranial cavity on the inner wall of the cranial cavity due to various reasons. Normal intracranial pressure value: Adult: normal value is 0.7~2.0kPa (70~200mmH20,5~15mmHg). Children: normal value is 0.5~1.0kPa (50~100mmH20,3.5~7.5mmHg)
Clinical manifestations: headache, vomiting and papilledema (the three main signs of increased intracranial pressure) 1. Headache: morning and night, the headache is mostly paroxysmal throbbing, persistent throbbing, and progressively worsens with the increase in intracranial pressure. 2. Vomiting: projectile, without aura, and not related to eating 3. Papilledema: one of the important objective signs of increased intracranial pressure 4. Disorders of consciousness and changes in vital signs: Acute: obvious progressive disturbance of consciousness and coma Chronic: manifested by apathy, slow reaction, coma Cushing reaction: increased blood pressure, increased pulse pressure difference, slow pulse, slow breathing (two slow and one high)
Note: When intracranial pressure is significantly increased, lumbar puncture may cause foramen magnum hernia and should be avoided. Analgesics can be given to those with headaches, but drugs such as morphine and pethidine should be avoided to prevent depression of the respiratory center.
Common Nursing Diagnoses/Problems
1. Acute/chronic pain: headaches are related to increased intracranial pressure 2. There is a risk of ineffective brain tissue perfusion: related to increased intracranial pressure and cerebral herniation. 3. There is a risk of insufficient body fluids: related to severe vomiting caused by increased intracranial pressure and the use of dehydrating agents 4. Potential complications: cerebral herniation, cardiac arrest
Nursing measures
General care: 1. Position: Elevate the head 15-30° to facilitate venous return 2. Give oxygen, continuously or intermittently for <60 minutes, avoid hyperventilation, maintain oxygen partial pressure 90-100㎜Hg, and carbon dioxide partial pressure 30-35㎜Hg 3. Limit the amount of intravenous infusion per adult, 1500-2000ml per person, isotonic saline ≤500ml, and maintain daily urine output of no less than 600ml 4. Maintain normal body temperature, prevent infection, cool down, and resist infection.
Closely observe changes in condition 1. Consciousness state: awake, blurred, light coma, coma and deep coma 2. Glasgow Scale (GCS) eyes opening, speech, movement (3-15 points, <8 means coma) 3. Pupil changes: size, shape, light reflection 4. Vital signs: pay attention to blood pressure, pulse and breathing 5. Intracranial pressure monitoring time is generally 7-14 days
Prevent increased intracranial pressure: 1. Rest in bed, stabilize your mood, keep your respiratory tract open, avoid severe coughing and straining to defecate, deal with agitation and control epileptic seizures
Medication care: 1. Dehydrating agent: hypertonic dehydrating agent (20% mannitol, initial amount 0.25-1g/kg, infused within 10-20 minutes) 2. Steroid corticosteroids, commonly used intravenous injection of dexamethasone 5-10 mg, 1-2 times a day 3. Barbiturates: commonly used phenobarbital
Mild hypothermia treatment care precautions: 1. First implement drug cooling. The cooling rate is preferably 1°C per hour. It is ideal for the body temperature to drop to a rectal temperature of 33-35°C. 2. Mild hypothermia therapy time is generally 3-5 days 3. The rewarming speed is controlled to increase by 1°C every 4 hours, and the rectal temperature returns to 36-37°C after 12 hours. 4. If the pulse exceeds 100 beats/minute, the systolic blood pressure is lower than 100㎜Hg, and the breathing is slow and irregular during treatment, the doctor should be notified in time to stop the medication.
Care of ventricular drainage: 1. Fix it properly, 10-15cm above the level of the lateral ventricle, and clamp it temporarily when moving 2. Keep drainage smooth: avoid draining too fast, and the drainage volume should not exceed 500ml/d. If there is cerebral fluid flowing out, you can squeeze and aspirate with the up and down fluctuations of breathing and pulse. Do not inject physiological saline. 3. Close observation: 1-2 days after surgery, the symptoms may turn slightly bloody and turn to orange-yellow. 4. Perform strict aseptic operation and replace drainage tubes every day 5. Extubate the tube in time, drainage time is 3-7 days, perform CT examination before extubation, and try to clamp the drainage tube for 24 hours
Cerebral herniation
Definition: When intracranial pressure continues to increase or malignant intracranial pressure increases, normal brain tissue squeezes from parts with higher pressure through gaps between brain tissues to parts with lower pressure, causing damage to cranial nerve function. caused a series of manifestations. The first manifestation is pupil changes, which may lead to unilateral pupil dilation or loss of eye light reflex. In severe cases, coma may occur.
Cerebral herniation is the most serious complication of increased intracranial pressure
clinical manifestations
Tentorial notch herniation: 1. Symptoms of increased intracranial pressure: severe headache, progressive aggravation, irritability, and frequent vomiting 2. Progressive disorder of consciousness: drowsiness, light coma, deep coma 3. Pupil changes: The pupil on the affected side is slightly narrowed and the light response is slow → The pupil on the affected side is dilated and the direct and indirect light response disappears, accompanied by upper eyelid ptosis and exotropia of the eyeball → Bilateral pupil is dilated and the light response disappears
Foramen magnum hernia: 1. Respiration slows, blood pressure rises → respiratory arrest → medullary function is affected 2. Severe headache, frequent vomiting, and disordered vital signs 3. Pain in the back of the neck, neck stiffness, forced head position, and cervical nerve root stretching 4. Consciousness disorder appears late
Nursing measures: Reduce intracranial pressure immediately and use 200-500ml of 20% mannitol as directed by the doctor. If respiratory arrest occurs due to foramen magnum hernia, tracheal intubation and assisted respiration should be performed immediately.
