Once the severity and nature of your head injury has been diagnosed, you will be given appropriate treatment. A severe head injury must always be treated in hospital. This is to minimise the risk of complications.
When you arrive at the emergency department of a hospital or if you call an ambulance, the doctors or paramedics (members of the emergency medical services) treating you will prioritise any injury that may be life threatening. This could mean:
- checking that your airway is clear
- checking that you are breathing, and starting cardio-pulmonary resuscitation (CPR or mouth-to-mouth) if you are not
- stabilising your neck and spine, for example using a neck brace
- stopping any severe bleeding
- providing pain relief if you are in a lot of pain
- splinting any fractured or broken bones (strapping them into the correct position)
Once you are stable, further treatment will be arranged, as necessary, including any tests that you need to help determine the severity of your injury. See Diagnosing severe head injury for more information about the tests you may have.
If you need to stay in hospital for observation, the doctors and nurses who are treating you will check:
- your Glasgow Coma Scale (GCS) score (a scale of 3 to 15 that assesses the extent of damage to your brain)
- the size of your pupils (the black circles in the middle of each eye) and whether they react to light
- how well you can move your arms and legs
- your breathing
- your heart rate
- your blood pressure
- your temperature
- the level of oxygen in your blood
These checks will be made every half an hour until your GCS score is 15 (the highest possible score). A GCS score of 15 indicates that you know where and who you are, you can speak and move as instructed and your eyes are open. After this, checks will be made less frequently.
Any changes in your condition or behaviour will also be closely monitored. If your condition worsens, you may need to have further tests, such as a computerised tomography (CT) scan (a scan that produces images of the inside of your body).
Cuts and grazes
If you have any external cuts or grazes to your head, these will be cleaned and treated to prevent further bleeding or infection. Deep or large cuts may require stitches (sutures) to keep them closed until they heal. Local anaesthetic (a painkilling medication) may be used to numb the area around the cut so that you do not feel any pain.
Neurosurgery is any kind of surgery that is used to treat a problem with the nervous system (the brain, spinal cord and nerves). In cases of severe head injury, neurosurgery is usually carried out on the brain.
Neurosurgery is required in 1-3% of people with a severe head injury. Every year in the UK, it is estimated that just under 4,000 people have neurosurgery following a head injury.
Possible reasons for neurosurgery include:
- a haemorrhage (severe bleeding) inside your head, which puts pressure on the brain and may result in brain injury (brain damage) and, in severe cases, death
- a haematoma (blood clot) inside your head, which can also put pressure on the brain
- cerebral contusions (bruises on the brain), which can develop into blood clots
- skull fracture (see below)
These conditions will be identified during tests, such as a CT scan, and a neurosurgeon (an expert in surgery of the brain and nervous system) may come and speak to you or your family about whether surgery is necessary.
As the above conditions can be serious and may require urgent treatment, in some cases there may not be time to discuss the surgery before it is carried out. After the operation, your surgeon will take the time to discuss the details of the surgery with both you and your family.
One possible type of surgery that may be required is a craniotomy.
A craniotomy is a type of surgery that involves making a hole in your skull (the bone in your head that surrounds your brain) so that the surgeon can access your brain. This will be carried out under general anaesthetic so that you are unconscious and cannot feel anything.
Once your surgeon has access to your brain, they will remove any blood clots that may have formed and repair any damaged blood vessels. Once any bleeding inside your brain has stopped, the piece of skull bone will be replaced and reattached.
Other surgical procedures
Depending on the type of damage to your brain, there are a number of other possible surgical procedures. Ask your surgeon for more information or see below if you have one of these conditions:
Your skull can fracture (crack) during an injury to your head. If this happens, you will usually have an X-ray to determine the extent of the injury.
There are different types of skull fractures, including:
- simple (or closed) fracture, where the skin has not broken and the surrounding tissue is not damaged
- compound (or open) fracture, where the skin has broken and the surrounding tissue may be damaged
- linear fracture, where the break in the bone looks like a straight line
depressed fracture, where part of the skull is crushed inwards
Open fractures may be more serious because there is a higher risk of infection if the skin is broken. This is because bacteria could enter the wound through the open skin. Depressed fractures may also be more serious because small pieces of bone can press inwards against the brain.
Treating skull fractures
Most skull fractures will heal by themselves, particularly if they are simple, linear fractures. The healing process can take many months, although any pain will usually disappear in around 5-10 days.
If the fracture is open, you may be prescribed antibiotics (medicines to treat infections that are caused by bacteria) to prevent an infection.
If the fracture is very severe or depressed, you may need to have surgery to help prevent any damage to the brain. This will usually be carried out under general anaesthetic.
During your operation, any pieces of bone that have been pressed inwards can be removed and returned to their correct position. If necessary, metal wire or mesh may be used to reconnect the pieces of your skull.
Once the bone is back in place, it should heal naturally. If you wish, your surgeon will explain the procedure that you are having in more detail.
Depending on how serious your operation was, you may need to recover in an intensive care unit (ICU). This is a small, specialised ward where your condition will be constantly monitored.
In an intensive care unit, you may be placed on a ventilator. This is an artificial breathing machine that moves oxygen-enriched air in and out of your lungs. The ventilator takes over some of your body's usual responsibilities, such as breathing, giving your body time to recover.
Once you are well enough, you will be moved to a ward and your condition will be observed, as described above.
The brain controls thought, memory and emotion. It sends messages to the body controlling movement, speech and senses.
Blood supplies oxygen to the body and removes carbon dioxide. It is pumped around the body by the heart.
Blood vessels are the tubes in which blood travels to and from parts of the body. The three main types of blood vessels are veins, arteries and capillaries.
To haemorrhage means to bleed or lose blood.
Body tissue is made up of groups of cells that perform a specific job, such as protecting the body against infection, producing movement or storing fat.
