Treatment Options
At the Hospital
At the
Scene of the Accident: Medical care
usually begins when paramedics or emergency
medical technicians arrive on the scene of
an accident or when a TBI patient arrives at
the emergency department of a hospital.
Because little can be done to reverse the
initial brain damage caused by trauma,
medical personnel try to stabilize the
patient and focus on preventing further
injury. Primary concerns include insuring
proper oxygen supply, maintaining adequate
blood flow, and controlling blood pressure.
Since many head-injured patients may also
have spinal cord injuries, the patient is
placed on a back-board and in a neck
restraint to prevent further injury to the
head and spinal cord.
Medical personnel assess the patient's
condition by measuring vital signs and
reflexes and by performing a neurological
examination. They check the patient's
temperature, blood pressure, pulse,
breathing rate, and pupil size and response
to light. They assess the patient's level of
consciousness and neurological functioning
using the Glasgow Coma Scale.
At the Hospital: Imaging tests help
in determining the diagnosis and prognosis
of a TBI patient. Patients with mild to
moderate injuries may receive skull and neck
X-rays to check for bone fractures. For
moderate to severe cases, the gold standard
imaging test is a computed tomography (CT)
scan, which creates a series of
crosssectional X-ray images of the head and
brain and can show bone fractures as well as
the presence of hemorrhage, hematomas,
contusions, brain tissue swelling, and
tumors. Magnetic resonance imaging (MRI) may
be used after the initial assessment and
treatment of the TBI patient. MRI uses
magnetic fields to detect subtle changes in
brain tissue content and can show more
detail than X-rays or CT. The use of CT and
MRI is standard in TBI treatment, but other
imaging and diagnostic techniques that may
be used to confirm a particular diagnosis
include cerebral angiography,
electroencephalography (EEG), transcranial
Doppler ultrasound, and single photon
emission computed tomography (SPECT).
Surgery: Approximately half of
severely head-injured patients will need
surgery to remove or repair hematomas or
contusions. Patients may also need surgery
to treat injuries in other parts of the
body. These patients usually go to the
intensive care unit after surgery.
Draining Fluid: Sometimes when the
brain is injured swelling occurs and fluids
accumulate within the brain space. It is
normal for bodily injuries to cause swelling
and disruptions in fluid balance. But when
an injury occurs inside the skull-encased
brain, there is no place for swollen tissues
to expand and no adjoining tissues to absorb
excess fluid. This increased pressure is
called intracranial pressure (ICP).
Medical personnel measure a patient's ICP
using a probe or catheter. The instrument is
inserted through the skull to the
subarachnoid level and is connected to a
monitor that registers the patient's ICP. If
a patient has high ICP, he or she may
undergo a ventriculostomy, a procedure that
drains cerebrospinal fluid (CSF) from the
ventricles to bring the pressure down. Drugs
that can be used to decrease ICP include
mannitol or barbiturates. |
