Contra-indications to ICP monitoring include coagulopathies or anti-coagulation medication, scalp infections, or brain abscess.
Full Answer
What are the harmful effects of intracranial hypertension (ICP)?
The harmful effects of intracranial hypertension are primarily due to brain injury caused by cerebral ischemia. Cerebral ischemia is the result of decreased brain perfusion secondary to increased ICP. Cerebral perfusion pressure (CPP) is the pressure gradient between mean arterial pressure (MAP) and intracranial pressure (CPP = MAP - ICP).[3]
What are the treatment options for elevated intracranial pressure (ICP)?
Avoid hypotonic fluid infusions in patients who may have elevated ICP. A fever increases ICP by increasing the brain’s metabolic demands and need for arterial blood supply. Patients with elevated ICP should be maintained at a normal temperature. In some cases this may be achievable with simple interventions (e.g., scheduled acetaminophen).

Does exercise make intracranial hypertension worse?
Since exertion can increase pressure inside the skull, symptoms can become worse with exercise or physical activity. Pseudotumor cerebri symptoms may resemble those of many other medical problems.
Is it OK to exercise with IIH?
On initial diagnosis, a weight-reduction diet should be strongly recommended to all patients with IIH. Often, a formal weight-loss program is required. No activity restriction is required in managing IIH. In fact, exercise programs are strongly recommended in conjunction with the weight-reduction diet.

What is intracranial pressure?
Intracranial pressure (ICP) is defined as the pressure within the craniospinal compartment, a closed system that comprises a fixed volume of neural tissue, blood, and cerebrospinal fluid (CSF).
How do you manage intracranial pressure?
Medical options for treating elevated ICP include head of bed elevation, IV mannitol, hypertonic saline, transient hyperventilation, barbiturates, and, if ICP remains refractory, sedation, endotracheal intubation, mechanical ventilation, and neuromuscular paralysis.
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 are the four stages of intracranial pressure?
Intracranial hypertension is classified in four forms based on the etiopathogenesis: parenchymatous intracranial hypertension with an intrinsic cerebral cause, vascular intracranial hypertension, which has its etiology in disorders of the cerebral blood circulation, meningeal intracranial hypertension and idiopathic ...
Does running increase intracranial pressure?
Exertion during physical activity can produce increases of varying degrees in blood pressure and intracranial pressure, which is why athletes can experience headaches of differing intensity and duration depending on the sport performed.
How do you know if you have an ICP?

How to reduce swelling in brain?
Medicine to reduce swelling. Draining extra cerebrospinal fluid or bleeding around the brain. Removing part of the skull (craniotomy) to ease swelling (though this is rare) You may also be treated for the underlying cause of your intracranial pressure, which could be an infection, high blood pressure, tumor, or stroke.
How many tiers of ICP elevation?
Treatment for ICP elevation can be loosely divided into three rough tiers, depending on how aggressive the treatments are (table below). Please note, however, that this is intended only as a rough cognitive rubric. It will often be appropriate to mix treatments from different tiers.
Why is noncommunicating hydrocephalus easier to diagnose?
Noncommunicating hydrocephalus is therefore easier to diagnose based on CT scans, because pressure differentials will cause shifts in brain tissue visible on CT.
What is CPP in a syringe?
CPP is the perfusion pressure of the brain. CPP is equal to the mean arterial pressure (MAP) minus either the central venous pressure (CVP) or intracranial pressure (ICP), whichever is higher. CPP should ideally be maintained above >60 mm.
Does elevation of head of bed reduce ICP?
Elevation of the head of the bed is widely recommended, but without a robust evidentiary basis. Elevation of the head of the bed will tend to reduce the ICP – but this comes at the cost of reducing the arterial perfusion in the brain.
Is lumbar puncture dangerous?
In the presence of focal pathology, lumbar puncture may be dangerous. This is particularly true in the case of noncommunicating hydrocephalus or mass lesions with threatened downward herniation. (as discussed above)
Can vasopressors increase CPP?
CPP can be rapidly improved using vasopressors. Elevation of the MAP with vasopressors may allow the CPP to be rapidly increased. Fluid administration is less effective at increasing the MAP, generally failing to achieve a sustained improvement in CPP. Typically, either norepinephrine or phenylephrine may be utilized.
Is papilledema accurate for ICP elevation?
Papilledema may be less accurate for immediate-onset intracranial hypertension, because it takes some time to develop. Papilledema may be useful for identifying ICP elevation in cases where the nerve sheath is borderline (e.g., between 5-6 mm wide). More on this here.
What is cranial sacral therapy?
Cranial sacral therapy can be used for people of all ages. It may be part of your treatment for conditions like: migraines and headaches. constipation. irritable bowel syndrome (IBS) disturbed sleep cycles and insomnia. scoliosis. sinus infections. neck pain.

study found that it was effective at reducing symptoms in those with severe migraines. Another study found that people with fibromyalgia experienced relief from symptoms (including pain and anxiety) thanks to CST.
Is cranial sacral therapy good for headaches?
Cranial sacral therapy may be able to provide relief for certain conditions, with the strongest evidence supporting it as a treatment for conditions like headaches. Because there’s a very low risk for side effects, some people may prefer this to prescription medications that come with more risks.
What are the signs of intracranial hypertension?
Common clinical signs of early intracranial hypertension include; headache, vomiting, irritability, seizures, photophobia, lethargy, nystagmus, and diplopia .#N#With severe intracranial hypertension, consciousness becomes depressed, tone and reflexes of the limbs are altered, pupils enlarge, papillary reaction to light is sluggish and spontaneous movement of the limbs is decreased. Signs may be unilateral or bilateral depending on the cause of the intracranial hypertension.#N#At a critically high level of ICP, spontaneous respiration is depressed, hypertension occurs, and heart rate is slowed, this is known as Cushing’s triad. Infants who have non-fused suture lines with open fontanel’s have a degree of compensation before signs of increased ICP are evident, such as macrocephaly.
When measuring and documenting ICP in a patient with an open EVD, it is crucial that the drainage
When measuring and documenting ICP in a patient with an open EVD, it is crucial that the drainage to the burette system be clamped, enabling a true ICP reading to be obtained from the patient (otherwise the drainage pressure will be recorded). Wait for the waveform to stabilize prior to documenting the reading (approximately 1 minute).
Where is ICP monitored?
ICP can be monitored via a fibre optic monitor (Codman™ microsensor) which is placed on the surface of the brain or in the brain or an external ventricular drain (EVD) system which is a closed sterile system allowing drainage of CSF via a silastic catheter tip which rests in the ventricle. The ventricular system produces CSF at approximately ...
When a patient with an EVD is being transported off the ward, the patient MUST be accompanied by
When a patient with an EVD is being transported off the ward, the patient MUST be accompanied by a competent RN. This RN must stay with the patient at all times until handed over to another accredited person.
What is the cranial vault?
The cranial vault contains brain tissue, blood and cerebrospinal fluid (CSF). After closure of a child’s sutures, the cranial vault is similar to a rigid box. As the volume of the three components within the skull (brain matter, blood and CSF) must remain equal, an increase in one component must be accompanied by a decrease in another component. If there is not, an increase in intracranial pressure (ICP) will occur.#N#ICP can be monitored via a fibre optic monitor (Codman™ microsensor) which is placed on the surface of the brain or in the brain or an external ventricular drain (EVD) system which is a closed sterile system allowing drainage of CSF via a silastic catheter tip which rests in the ventricle.#N#The ventricular system produces CSF at approximately 20mL/hr (estimated at 0.35mL/min in children) by the choroid plexus in the lateral ventricles. The CSF circulates around the brain and spinal cord and is then reabsorbed via the arachnoid villi.
Etiology
Meningitis is defined as inflammation of the meninges. The meninges are the three membranes (the dura mater, arachnoid mater, and pia mater) that line the vertebral canal and skull enclosing the brain and spinal cord ( encephalitis is inflammation of the brain itself).
Epidemiology
The incidence of meningitis is 2 of 6 per 10,000 adults per year in developed countries and is up to ten times higher in less-developed countries.
Diagnostic Tests
Meningitis is diagnosed through cerebrospinal fluid (CSF) analysis, which includes white blood cell count, glucose, protein, culture, and in some cases, polymerase chain reaction (PCR). CSF is obtained via a lumbar puncture (LP), and the opening pressure can be measured.
Complications
The median risk of sequelae post-discharge was 19.9% (2010 metaanalysis). The most common organism isolated was H. influenzae, followed by S. pneumoniae. The most common sequelae were hearing loss (6%), followed by behavioral (2.6%) and cognitive difficulties (2.2%), motor deficit (2.3%), seizure disorder (1.6%) and visual impairment (0.9%).
