Next Steps on Head Injuries

November 11th, 2010

Prevention on head injuries:

* Sensible prevention includes wearing helmets when bike riding, inline skating, driving motorcycles, and other similar activities.
* Safety belts, car seats, and airbags when used properly can prevent head injuries in motor vehicle accidents.
* Drinking while driving is one of the most common causes of motor vehicle crashes. Many serious head injuries would be prevented by avoiding this dangerous behavior.
* Fall-proofing includes checking your home for areas where someone may fall: stairs, bathtubs, throw rugs, and furniture.

Medical Head Injury Treatment

November 10th, 2010

Treatment varies widely depending on the type and severity of injuries.

* Minor head injuries are often treated at home as long as someone is available to watch the person.

- Bed rest, fluids, and a mild pain reliever, for example, acetaminophen (Tylenol) may be prescribed. Ice may be applied to the scalp for pain relief and to decrease swelling.
- Cuts will be numbed with a medication usually given by injection. They will then be cleansed. The doctor will then look for foreign matter and hidden injuries. The wound usually is closed with skin staples, stitches (sutures), or skin glue. Tetanus immunization will be updated if needed.

* People with serious closed head injuries are almost always admitted to the hospital for observation and repeated studies to assure that the condition does not worsen.

- Occasionally a head injury may cause elevated pressure within the skull. An intracranial pressure (ICP) monitor probe may be surgically inserted into the brain through the skull to measure the pressure. If the pressure rises too high, it may be necessary to do surgery to decompress the brain. Death is possible. Intravenous medications may be used to control intracranial pressure as a temporizing measure until the crisis resolves or surgery is performed.
- Medication to prevent seizures may be given to prevent or treat seizures that occur from the head injury. Seizures after head injury often do not require treatment because they may not reoccur.
- Antibiotics are usually not required in closed head injuries. Some doctors use antibiotics in all cases of basilar skull fracture. Other doctors do not feel this is useful.

* When there is a closed head injury with bleeding inside the skull, the doctor must consider a number of factors to determine the correct treatment. Some of these include the location of the bleeding, severity of the symptoms, the presence of any other injuries, and progression of symptoms. Surgery may be needed. Other options include pressure monitors, medication to prevent seizures, and antibiotics to prevent infection. People with this type of injury may need a breathing tube inserted (intubation) to help prevent further brain injury. Angiography may be performed.

* Penetrating head injuries often require some sort of surgery, usually to remove foreign material or to stop bleeding. Other options include pressure monitors, medication to prevent seizures, and antibiotics to prevent infection. People with this type of injury may need a breathing tube inserted. Angiography may be performed.

Head Injury Treatment

November 9th, 2010

Emergency medical personnel should immediately treat any serious or potentially serious head injury.

Minor head injuries may be cared for at home.

Bleeding under the scalp, but outside the skull, creates “goose eggs” or large bruises at the site of a head injury. They are common and will go away on their own with time. Using ice immediately after the trauma may help decrease their size.

- Do not apply ice directly to the skin. Ice should be applied for 20-30 minutes at a time and can be repeated about every 2-4 hours as needed.
- Use a light washcloth as a barrier and wrap the ice in it. You can also use a bag of frozen vegetables wrapped in cloth. This conforms nicely to the shape of the head.
- Make your own ice pack by adding 1/3 cup of 70% isopropyl alcohol (the green-colored kind is best to help identify it later) to 2/3 cup of water in a zip-lock-style bag (double bag it to prevent leaking). The mixture turns into “slush.” Freeze this homemade ice pack for use when needed. Caution: If you have small children in your home, watch them carefully when using the ice pack. Drinking the mixture can be poisonous.
- Commercially available ice packs use chemicals to create cold. They are designed to be kept in a first-aid kit and need not be kept frozen. These can be applied directly to the skin, although a barrier can also be used if bleeding is present. They must be disposed of after a single use but can be handy in case of emergencies.

When a minor head injury results from a fall onto carpet or other soft surface and the height of the fall is less than the height of the person who fell and there is no loss of consciousness (in other words, the person was not “knocked out”), a doctor’s visit is not usually needed. Apply ice to lessen swelling.

Head Injury Exams and Tests

November 8th, 2010

Despite the availability of modern diagnostic tools such as CT scanning, the physical examination and the history of the exact details of the injury, the person’s past medical history, and the symptoms are often the most important information the doctor uses to make treatment decisions. When possible be sure to bring all medications or a list of medications with the injured person to the hospital or doctor’s office.

* Skull x-rays: The doctor may order x-rays to look for a fracture (break) in the skull bone. The presence of a skull fracture on x-ray does not mean there has been an injury to the brain, and the absence of a fracture does not exclude a brain injury. With or without a fracture, the most critical factor is determining if a brain injury is present. Even if a fracture is found, doctors do not put casts on the heads of people with skull fractures like they would with a broken arm. The fracture itself will seldom need treatment, but an underlying brain injury may. Skull x-rays are not taken as frequently now as in the past.

- If the potential for a serious injury to the brain exists, the doctor may order a CT scan.
- Many doctors will order skull x-rays in children younger than 1 year.
- Skull x-rays are also often used for people with a history of penetrating injuries or possible penetrating injuries to the skull (a bullet may appear to have been a graze wound, but an x-ray may tell for sure).
- It may be easier to see where foreign bodies are located and how many there are with a regular x-ray than with a CT scan.

One reason for doctors to order skull x-rays for a child is in anticipation of a possible leptomeningeal cyst. Also known as growing skull fracture, this is a rare complication of skull fracture seen in children younger than 3 years. It occurs when a skull fracture fails to heal properly. Six or more months after the initial injury, the fracture may begin to widen instead of healing. Usually parents will notice swelling, which gradually increases in size. This is not predictable nor preventable but should be treated by a neurosurgeon if it occurs. Swelling or masses noted in the first few weeks to months after a head injury in children are referred to as a “pseudo-growing fracture.” They do not need treatment and will go away on their own but should be brought to your pediatrician’s attention so they can be watched.

* CT scan is the test used most often to evaluate acute head injuries. A CT is useful for identifying injuries to the brain itself. Not all head injuries require the brain to be imaged. Clinical judgment is important, and decision-making rules have been developed to help health care practitioners use technology wisely and limit the amount of lifetime radiation provided to patients. These decision rules can help predict which patients will have a normal CT scan of the head.

The CT is essentially an X-ray machine that takes multiple X-rays from many angles around the head. A computer uses these X-ray images to make a picture of the brain and other structures inside the skull. The picture is usually displayed as two-dimensional “slices” of various levels of the brain. Three-dimensional images may be made but are usually not necessary for evaluation of head injuries. The details on a CT scan are very good, and even small spots of blood may be identified.

* MRI scans are rarely used immediately after head injuries. The MRI may be used later for additional information about a brain injury.

* In some cases of bleeding in or around the brain, angiography may be performed to visualize the blood vessels. This test involves injecting dye into the arteries of the head. X-rays are taken that show the blood vessels and may show exactly where bleeding is occurring. In some cases it is possible to stop the bleeding during angiography. This involves injecting special materials into the bleeding blood vessel and causing a clot to form. If this procedure is successful, the bleeding is stopped without the need for surgery. Alternatively, computerized tomography with angiography can be done to look at blood vessel anatomy.

* Other x-rays and lab tests may be performed to look for other illnesses or injuries. For example, neck injuries are common in people with severe head trauma. Spine x-rays are usually ordered before the head is moved if there is any neck pain or other symptoms of a neck injury. In a car accident, there may also be chest or abdominal injuries.

When to Seek Medical Care on Head Injuries

October 27th, 2010

Emergency personnel should immediately attend to all potentially serious head injuries. Call the doctor to ask about any of the following situations. Your doctor will recommend home care, set up an appointment to see you, or direct you to go to a hospital’s Emergency Department.

* A person is pushed to the ground or struck a hard object with the head but did not lose consciousness
* Vomiting more than once
* Confusion
* Drowsiness
* Weakness or inability to walk
* Severe headache

Go to the Emergency Department by ambulance in the following situations. People with less severe injuries may be taken by car to the Emergency Department.

* Severe head trauma or a fall from more than the height of the person or a hard fall onto a hard surface or object
* Loss of consciousness for more than 1 minute, vomiting more than once, confusion, drowsiness, weakness or inability to walk, or severe headache (prevent movement of the neck in severe head injury or if the injured person has any neck pain. If the person needs to vomit, carefully roll them onto their side without turning the head).
* Should an injured person be allowed to fall asleep? Many people mistakenly believe that it is important to keep a person awake after they have been struck on the head. Children often are more emotionally disturbed than they are physically injured after a minor fall. They will cry and be upset, but as the parent rushes them to the hospital, the child may begin to calm down. They have expended a lot of physical and emotional energy by crying and then will often want to fall asleep.

You do not need to keep a child or other victim of head injury awake. In many cases it is even helpful to the emergency doctor to be able to awaken a child who is now calm and rested and able to behave normally. This gives the doctor a much better assessment of the severity of the head injury.

If a person who was initially normal after a head injury cannot be awakened or is extremely difficult to awaken, he or she may have a more serious head injury and should be evaluated by a doctor.

Head Injury Symptoms

October 26th, 2010

Signs and symptoms of head injuries vary with the type and severity of the injury.

* Minor blunt head injuries may involve only symptoms of being “dazed” or brief loss of consciousness. They may result in headaches or blurring of vision or nausea and vomiting. There may be longer lasting subtle symptoms including, irritability, difficulty concentrating, insomnia, and difficulty tolerating bright light and loud sounds. These post concussion symptoms may last for a prolonged period of time.

* Severe blunt head trauma involves a loss of consciousness lasting from several minutes to many days or longer. Seizures may result. The person may suffer from severe and sometimes permanent neurological deficits or may die. Neurological deficits from head trauma resemble those seen in stroke and include paralysis, seizures, or difficulty with speaking, seeing, hearing, walking, or understanding.

* Penetrating trauma may cause immediate, severe symptoms or only minor symptoms despite a potentially life-threatening injury. Death may follow from the initial injury. Any of the signs of serious blunt head trauma may result.

Head Injury Causes

October 21st, 2010

All types of head injuries can be caused by trauma. In adults in the United States such injuries commonly result from motor vehicle accidents, assaults, and falls. In children falls are the most common cause followed by recreational activities such as biking, skating, or skateboarding. A small but significant number of head injuries in children are from violence and abuse.

* Penetrating trauma: Missiles such as bullets or sharp instruments (such as knives, screwdrivers, or ice picks) may penetrate the skull. The result is called a penetrating head injury. Penetrating injuries often require surgery to remove debris from the brain tissue. The initial injury itself may cause immediate death, especially if from a high-energy missile such as a bullet.

* Blunt head trauma: These injuries may be from a direct blow (a club or large missile) or from a rapid deceleration force (a fall or striking the windshield in a car accident).

Intracranial Hemorrhage and Headaches

October 18th, 2010

About intracranial (inside the skull) hemorrhage (bleeding)

* Subdural hematoma: Bleeding between the brain tissue and the dura mater (a tough fibrous layer of tissue between the brain and skull) is called a subdural hematoma. The stretching and tearing of “bridging veins” between the brain and dura mater causes this type of bleeding. A subdural hematoma may be acute, developing suddenly after the injury, or chronic, slowly accumulating after injury. Chronic subdural hematoma is more common in the elderly whose bridging veins are often brittle and stretched and can more easily begin to slowly bleed after minor injuries. Subdural hematomas are potentially serious and may require surgery.

* Epidural hematoma: The skull is made up of a variety of bones; the dura, the thick membrane that wraps around the brain, attaches at the suture lines where the bones come together. If bleeding occurs in the enclosed space between the dura and the bone, and a hematoma (blood clot) forms, there is nowhere for it to accumulate and pressure within the epidural space can build quickly. The increasing pressure pushes the hematoma against the brain tissue and may cause significant damage.

Tiny epidural hematomas potentially may be observed without surgery, but often surgery is indicated to removed the hematoma and relieve the pressure on the brain. The earlier the operation, the better, because the death rate increases if the patient is in a coma at the time of operation.

An epidural hematoma may often occur with trauma to the temporal bone located on the side of the head above the ear. Aside from the fact that the temporal bone is thinner than the other skull bones (frontal, parietal, occipital), it is also the location of the middle meningeal artery that runs just beneath the bone. Fracture of the temporal bone is associated with tearing of this artery and may lead to an epidural hematoma.

* Subarachnoid hemorrhage: Subarachnoid hemorrhage can be caused by trauma and often does not require surgery. Blood accumulates in the space beneath the arachnoid layer that surrounds the brain. While this can irritate the brain and cause symptoms of headache, vomiting, and stiff neck, treatment may be watchful waiting without surgery unless symptoms worsen.

* Intraparenchymal hemorrhage/cerebral contusion: These terms describe bleeding into the brain tissue itself. A contusion is like a bruise to the brain tissue and usually requires no special intervention, much like a concussion. Most doctors admit people with cerebral (brain) contusion to the hospital for observation since there may be rare complications such as brain swelling. An intraparenchymal hemorrhage is a pool of blood within the brain tissue. Minor bleeding may stop without any treatment and cause no serious problems. More serious or large bleeds usually require surgery.

Skull Fractures and Headaches

October 14th, 2010

A skull fracture is a break in the bone surrounding the brain and other structures within the skull.

* Linear skull fracture: A common injury, especially in children. A linear skull fracture is a simple break in the skull that follows a relatively straight line. It can occur after seemingly minor head injuries (falls, blows such as being struck by a rock, stick, or other object; or from motor vehicle accidents). A linear skull fracture is not a serious injury unless there is an additional injury to the brain itself.

* Depressed skull fractures: These are common after forceful impact by blunt objects-most commonly, hammers, rocks, or other heavy but fairly small objects. These injuries cause “dents” in the skull bone. If the depth of a depressed fracture is at least equal to the thickness of the surrounding skull bone (about 1/4-1/2 inch), surgery is often required to elevate the bony pieces and to inspect the brain for evidence of injury. Minimally depressed fractures are less than the thickness of the bone. Other fractures are not depressed at all. They usually do not require surgical treatment unless other injuries are noted.

* Basilar skull fracture: A fracture of the bones that form the base (floor) of the skull and results from severe blunt head trauma of significant force. A basilar skull fracture commonly connects to the sinus cavities. This connection may allow fluid or air entry into the inside of the skull and may cause infection. Surgery is usually not necessary unless other injuries are also involved.

Head Injury

October 13th, 2010

Head injury refers to trauma to the head. This may or may not include injury to the brain. However, the terms traumatic brain injury and head injury are often used interchangeably in the medical literature.

The incidence (number of new cases) of head injury is 300 per 100,000 per year (0.3% of the population), with a mortality of 25 per 100,000 in North America and 9 per 100,000 in Britain. Head trauma is a common cause of childhood hospitalization.

Head injuries include both injuries to the brain and those to other parts of the head, such as the scalp and skull. Head injuries may be closed or open. A closed (non-missile) head injury is one in which the skull is not broken. A penetrating head injury occurs when an object pierces the skull and breaches the dura mater. Brain injuries may be diffuse, occurring over a wide area, or focal, located in a small, specific area.

A head injury may cause a minor headache skull fracture, which may or may not be associated with injury to the brain. Some patients may have linear or depressed skull fractures.

If intracranial hemorrhage occurs, a hematoma within the skull can put pressure on the brain. Types of intracranial hemorrage include subdural, subarachnoid, extradural, and intraparenchymal hematoma. Craniotomy surgeries are used in these cases to lessen the pressure by draining off blood.

Brain injury can be at the site of impact, but can also be at the opposite side of the skull due to a contrecoup effect (the impact to the head can cause the brain to move within the skull, causing the brain to impact the interior of the skull opposite the head-impact).

If the impact causes the head to move, the injury may be worsened, because the brain may ricochet inside the skull causing additional impacts, or the brain may stay relatively still (due to inertia) but be hit by the moving skull (both are contrecoup injuries).

Synonyms: head trauma, concussion, subdural hematoma, diffuse axonal injury, epidural hematoma, closed head injury, cerebral contusion, intracranial hemorrhage, head bleed, intraparenchymal hemorrhage, DIA, depressed skull fracture, nondepressed skull fracture, linear skull fracture, penetrating head trauma, basilar skull fracture, head injury, headache, worst headache of your life, brain dead, brain death, fatal head injury, subarachnoid head injury, subdural hematoma, blood clot in the brain and burst blood vessel in the brain.

Specific problems after head injury can include:

* Skull fracture
* Lacerations to the scalp and resulting hemorrhage of the skin
* Traumatic subdural hematoma, a bleeding below the dura mater which may develop slowly
* Traumatic extradural, or epidural hematoma, bleeding between the dura mater and the skull
* Traumatic subarachnoid hemorrhage
* Cerebral contusion, a bruise of the brain
* Concussion, a temporary loss of function due to trauma
* Dementia pugilistica, or “punch-drunk syndrome”, caused by repetitive head injuries, for example in boxing or other contact sports
* A severe injury may lead to a coma or death
* Shaken Baby Syndrome – a form of child abuse
