Consequently an ICP monitor is recommended after a craniotomy particularly when there are other associated factors, e.g., hypoxia, hypotension, pupil abnormalities, midline shift >5 mm, brain swelling at surgery, and when patients may require other surgeries for extracranial injuries.
What are the indications for ICP monitoring?
- moderate -> severe head injury who can’t be serially neurologically assessed.
- severe head injury (GCS < 8) + abnormal CT scan.
- severe head injury (GCS < 8) + normal CT if 2 of the following are present: Age > 40 yrs. BP < 90mmHg. Abnormal motor posturing.
What is ICP monitoring used for?
Intracranial pressure (ICP) monitoring is a diagnostic test that helps your doctors determine if high or low cerebrospinal fluid (CSF) pressure is causing your symptoms. The test measures the pressure in your head directly using a small pressure-sensitive probe that is inserted through the skull.
What is the gold standard for ICP monitoring?
The gold standard for ICP monitoring is through an intraventricular catheter, but this invasive technique is associated with certain risks.
Is ICP an emergency?
Key points about increased ICP
Increased ICP is a dangerous condition. It is an emergency. It requires medical care right away. Increased ICP can result from bleeding in the brain, a tumor, stroke, aneurysm, high blood pressure, or brain infection.
Does ICP monitoring improve outcomes?
ICP monitoring may not reduce the risk of hospital mortality, but plays a role in decreasing the rate of electrolyte disturbances, rate of renal failure, and increasing favorable functional outcome. You may also read,
How do I know if I have ICP?
- Headache.
- Blurred vision.
- Feeling less alert than usual.
- Vomiting.
- Changes in your behavior.
- Weakness or problems with moving or talking.
- Lack of energy or sleepiness.

What are complications of ICP monitoring?
There are several potential complications associated with ICP monitors and, in particular, brain hemorrhage, infection, and technical failure. The overall risk of clinically significant complications is low.
What does increased ICP cause?
A sudden increase in the pressure inside a person’s skull is a medical emergency. Left untreated, an increase in the intracranial pressure (ICP) may lead to brain injury, seizure, coma, stroke, or death. With prompt treatment, it is possible for people with increased ICP to make a full recovery. Read:
How do I lower my ICP?
Interventions to lower or stabilize ICP include elevating the head of the bed to thirty degrees, keeping the neck in a neutral position, maintaining a normal body temperature, and preventing volume overload. The patient must be stabilized before transport to radiology for brain imaging.
What is a normal reading for ICP?
For the purpose of this article, normal adult ICP is defined as 5 to 15 mm Hg (7.5–20 cm H2O). ICP values of 20 to 30 mm Hg represent mild intracranial hypertension; however, when a temporal mass lesion is present, herniation can occur with ICP values less than 20 mm Hg [5].
What are the methods used to ICP monitoring?
Intracranial pressure (ICP) monitoring is a staple of neurocritical care. The most commonly used current methods of monitoring in the acute setting include fluid-based systems, implantable transducers and Doppler ultrasonography. It is well established that management of elevated ICP is critical for clinical outcomes.
What are the late signs of raised ICP?
Late signs include motor changes (hemiparesis), raised blood pressure, widened pulse pressure and slow irregular pulse. Acute situations: Head injury and obtundation: bleeding can form a rapidly expanding haematoma leading to rapidly rising ICP if not treated promptly.
What does an ICP headache feel like?
Pseudotumor cerebri headaches usually feel like a headache that occurs at the back of the head or behind the eyes. The pain starts as a dull, aching pain that worsens at night or in the morning. They may be associated with vomiting as well.
Does intracranial pressure increase when lying down?
Pressures in the skull are higher when patients are lying down than when sitting or standing, and there is strong evidence that this difference between pressures when lying and sitting is higher in patients with a working shunt, and lower in patients without a shunt.
What does brain swelling feel like?
Symptoms of brain swelling include headache, dizziness, nausea, numbness or weakness, loss of coordination or balance, loss of the ability to see or speak, seizures, lethargy, memory loss, incontinence, or altered level of consciousness.
