What is epidural and subdural hematoma?
Location: An epidural hematoma (EDH) occurs between your skull and the outermost layer of meninges, the dura mater. A subdural hematoma occurs in the space between the dura mater and the second meninges layer, the arachnoid layer.
What is EDH in brain?
An epidural hematoma (EDH) is bleeding between the inside of the skull and the outer covering of the brain (called the dura).
What are the signs and symptoms of an epidural hematoma?
Some of the most common signs and symptoms of an epidural hematoma include:
- vomiting.
- confusion.
- seizures.
- loss of vision on one side.
- dizziness.
- changes in breathing.
- nausea.
- severe headache.
What causes subdural or epidural hematoma?
An epidural hematoma usually results from trauma or other injury to your head. For example, your brain may be subjected to a damaging blow during a fall, vehicular accident, or collision in contact sports. Physical abuse can also cause head injury and lead to an epidural hematoma.
Where is epidural hematoma?
What is treatment for epidural hematoma?
In most cases, your doctor will recommend surgery to remove an epidural hematoma. It usually involves a craniotomy. In this procedure, your surgeon will open up part of your skull so they can remove the hematoma and reduce the pressure on your brain. In other cases, your doctor may recommend aspiration.
Why is mannitol contraindicated in EDH?
Mannitol may pass and accumulate in the brain, causing a reverse osmotic shift or rebound effect, and raising brain osmolarity, thus increasing ICP [82,83]. Mannitol is contraindicated in patients with TBI and renal failure because of the risk of pulmonary edema and heart failure.
What is the difference in CT scan between subdural and epidural hematoma?
Subdural hematomas are concave toward the brain and unlimited by suture lines, as opposed to epidural hematomas, which are convex toward the brain and restricted by suture lines. Rarely, a subdural hematoma appears lens shaped (ie, more like an epidural hematoma).
What is the treatment for epidural hematomas?
What is the most common cause of epidural hematoma?
The fractures are most often the result of a severe head injury, such as those caused by motorcycle, bicycle, skateboard, snow boarding, or automobile accidents. Rapid bleeding causes a collection of blood (hematoma) that presses on the brain. The pressure inside the head (intracranial pressure, ICP) increases quickly.
What are the side effects of having an epidural?
Side effects Epidural
- Low blood pressure. It’s normal for your blood pressure to fall a little when you have an epidural.
- Loss of bladder control.
- Itchy skin.
- Feeling sick.
- Inadequate pain relief.
- Headache.
- Slow breathing.
- Temporary nerve damage.
Can we give mannitol in SDH?
If SDH is causing brain herniation, as evidenced by oculomotor palsy or Cushing’s reflex (bradycardia, hypertension, and irregular respirations), hyperosmolar therapy with mannitol (an osmotic diuretic) should be considered. Mannitol general dosing is 0.25 to 1 gm/kg i.v. bolus given as quickly as possible.
Do you give mannitol in epidural hematoma?
Medication Summary Osmotic diuretics, such as mannitol or hypertonic saline, may be used to diminish intracranial pressure. As hyperthermia may exacerbate neurological injury, acetaminophen may be given to reduce fevers. Anticonvulsants are used routinely to avoid seizures that may be induced by cortical damage.
Can mannitol be given in EDH?
Use of mannitol for controlling increased intracranial pressure (ICP) upon the arrival at emergency department was higher in the patients with poor outcome (10/14, 71.43%). On the other hand, those with good outcome received no treatment of mannitol for EDH (29/60, 48.33%).
How is subdural hematoma diagnosed?
Brain scans Most people with a suspected subdural haematoma will have a CT scan to confirm the diagnosis. A CT scan uses X-rays and a computer to create detailed images of the inside of your body. It can show whether any blood has collected between your skull and your brain.
How is an epidural hematoma diagnosed?
A non-contrast head CT scan will confirm the diagnosis of EDH, and will pinpoint the exact location of the hematoma and any associated skull fracture. MRI may be useful to identify small epidural hematomas from subdural ones.
What is the most common cause of subdural hematomas?
Subdural haematomas are usually caused by a head injury. Head injuries that cause subdural haematomas are often severe, such as from a car crash, fall or violent assault. Minor bumps to the head can also lead to a subdural haematoma in a few cases.
