What is a Ventriculostomy?
Ventriculostomy (or ventric) is a device to drain excess cerebrospinal liquid (CSF). After brain surgery, head injuries, or ruptured aneurysms, excess CSF and blood may build up in the head. The brain can be put under extreme pressure. The fluid presses against the brain tissue and slows down blood flow.
Afterwards, you might also wonder, "How does an EVD function?"
The EDV tube connects with a collection system which allows the CSF to drain into a bag suspended on a pole. To maintain the correct brain fluid pressure, the surgeon will adjust the pressure levels. The EVD line is adjusted by the nurse to match your child's ears.
Also, learn how to level Ventriculostomy. EVD / ICP zeroing
- An ICP cable must be used to connect the Phillips monitor to the ICP transducer.
- Wash your hands with soap and water.
- The 3 way tap on EVD system should be turned off (leave the system open for the transducer).
Many people also wonder what a Ventriculostomy Drain is.
An external ventricular drainage (EVD), also called a ventriculostomy, extraventricular drain or ventriculostomy, is a neurosurgical device that is used to treat hydrocephalus. It is used to relieve intracranial pressure and reduce cerebral fluid (CSF) obstructing normal cerebrospinal fluid flow.
What length of time can an EVD last?
It varies from one child to the next, depending on why EDVD was necessary in the first instance. It is a temporary way to drain CSF. is seldom used for longer than 14 days. Your child must remain in hospital while the drainage system has been removed.

What is the best position for a patient with increased intracranial pressure?
In most patients with intracranial hypertension, head and trunk elevation up to 30 degrees is useful in helping to decrease ICP, providing that a safe CPP of at least 70 mmHg or even 80 mmHg is maintained. Patients in poor haemodynamic conditions are best nursed flat.
What is the purpose of a Ventriculostomy?
A ventriculostomy is a device that drains excess cerebrospinal fluid from the head. It is also used to measure the pressure in the head (referred to as ICP, intracranial pressure). The system is made up of a small tube, drainage bag, and monitor. Sometimes the ventriculostomy is called a “ventric” for short.
What is an early sign of increased intracranial pressure?
In general, symptoms and signs that suggest a rise in ICP include headache, vomiting without nausea, ocular palsies, altered level of consciousness, back pain and papilledema. If papilledema is protracted, it may lead to visual disturbances, optic atrophy, and eventually blindness.
What is an EVD infection?
External ventricular drainage (EVD) is frequently used in neurosurgery to drain cerebrospinal fluid in patients with raised intracranial pressure. The cumulative incidence of EVD-related infections was 8.3% (95% CI, 5.3–12.7) with a device-associated infection rate of 10.4 per 1000 drainage days (95% CI, 6.2–16.5).
What is the opening pressure lumbar puncture?
Opening Pressure at Lumbar Puncture is a surrogate measurement of Intracranial Pressure. An accurate Opening Pressure requires the needle entry point to be on the same level as the midline of the spine (Figure 4), which should also be at the same level as the patient's head.
How many ventricles are there in the brain?
four ventricles
How do you test for ICP?
How is increased ICP diagnosed?
- A nervous system exam. This is to test your senses, balance, and mental status. Sometimes your healthcare provider can tell if pressure is high by looking into your eye with an ophthalmoscope.
- Spinal tap (lumbar puncture). This test measures the pressure of cerebrospinal fluid.
What is the life expectancy of someone with hydrocephalus?
Hydrocephalus is a chronic condition. It can be controlled, but usually not cured. With appropriate early treatment, however, many people with hydrocephalus lead normal lives with few limitations. Hydrocephalus can occur at any age, but is most common in infants and adults age 60 and older.
What is a lumbar drain for?
A lumbar drain is a small, flexible, soft plastic tube placed in the lower back (lumbar area) to remove cerebral spinal fluid (CSF). A lumbar drain is often needed to collect CSF from the spine after surgery or to reduce pressure in the spinal cord or brain.
What happens if you drain too much CSF?
Causes. Hydrocephalus occurs when too much fluid builds up in the brain; specifically, excess CSF (cerebrospinal fluid) accumulates in the cavities (ventricles) of the brain. There are more than 100 possible causes of hydrocephalus, but the underlying reasons are: Too much CSF is produced.
What is an EVT procedure?
Endoscopic third ventriculostomy (ETV) is a surgical procedure for treatment of hydrocephalus in which an opening is created in the floor of the third ventricle using an endoscope placed within the ventricular system through a burr hole.
Does hydrocephalus always require surgery?
The most common treatment for hydrocephalus is the surgical insertion of a drainage system, called a shunt. People who have hydrocephalus usually need a shunt system for the rest of their lives, and regular monitoring is required.
How do EVD drains work?
External drainage and monitoring is the temporary drainage of cerebrospinal fluid (CSF) from the lateral ventricles of the brain, or the lumbar space of the spine, into an external collection bag. An external ventricular drainage (EVD) system drains CSF by using a combination of gravity and intercerebral pressure.
What are the principal risk factors associated with Ventriculostomy procedure?
The major potential risks of ventriculostomy placement are ventriculostomy-related infection (VRI) or insertional hemorrhage. A recent review of VRI indicated that a body of retrospective studies was limited by nonuniform definitions of infection versus colonization versus contamination.
What is a subdural drain?
The accumulated blood is washed out through these holes. Sometimes, at the end of surgery, surgeons insert a soft silicone drain through one burr hole to continue to drain the space previously occupied by the blood (subdural drainage).
What is chronic hydrocephalus?
Chronic hydrocephalus is a complex condition, the incidence of which increases with increasing age. It is characterised by the presence of ventricular enlargement in the absence of significant elevations of intracranial pressure. In some cases the cause of the hydrocephalus remains obscure ("idiopathic" NPH).
What is ICP monitoring nursing care?
Nursing interventions can positively or negatively affect intracranial pressure (ICP). Nurses have a unique opportunity to manage patient care in order to decrease elevated ICP and prevent secondary brain injury. It becomes a delicate balance to maintain brain function while helping to prevent other secondary injury.
