Why does increased intracranial pressure cause projectile vomiting?

Why does increased intracranial pressure cause projectile vomiting?

Not sure: Increased pressure in the brain/skull is often associated with vomiting. We don't know exactly how the pressure triggers the vomiting center in the brainstem, it just does. Since sudden onset of headache and vomiting can be a sign of a serious condition see you doctor immediately. This is especially true if the vomiting occurs during the night while sleeping.

Projectile Vomiting (Definition)

For example, a child sitting on your lap and projectile vomiting could completely clear your lap with the material vomited, forcefully projecting it away from himself. This often occurs when there is an obstruction to emptying the stomach at the pyloris, a muscle at the far end of the stomach where it ...Read more

Will fludrocortisone 0.1mg cause a lot of increased intracranial pressure? Just wondered.

Will fludrocortisone 0.1mg cause a lot of increased intracranial pressure? Just wondered.

May or may not: Fludrocortisone is mineralocortcoid helps body to retain sodium. It depends why one is taking this drud, if one has salt retaining hormone deficiency like addison disease and is taking right dose then no side effects. Excess of it can cause high blood pressure bu not increas intracranial pressure. This drug is also used for orthodtatic low blood pressure. In summary it can cause high blood press.

Could brain tumors always cause increased intracranial pressure?

Could brain tumors always cause increased intracranial pressure?

It depends on size: There is limited space inside the skull. So any space occupying lesion causes rise in intracranial pressure once it gets to a size above 1 or 2 cms.

Why does hypertension cause increased intracranial pressure?

Can bilateral mydriasis indicate increased intracranial pressure? Both my pupils react evenly, but my doctor was still surprised at this.

Can bilateral mydriasis indicate increased intracranial pressure? Both my pupils react evenly, but my doctor was still surprised at this.

Mydriasis: Or pupil dilation is quite common in younger people. They tend to have naturally larger pupils. As long as they are equal and both react well, then this is totally normal. On the other hand, an increase in intracranial pressure can cause one or both pupils to dilate but typically they don't react well in this situation.

If increased intracranial pressure (icp) is contraindicated in lumbar puncture, why one of the indication of this procedure is to decrease the icp?

If increased intracranial pressure (icp) is contraindicated in lumbar puncture, why one of the indication of this procedure is to decrease the icp?

Different situations: It depends on the clinical situation. If there is a mass lesion in the brain that causes a differential pressure between the supratentorial and infratentorial areas, lumbar puncture can accentuate the difference and lead to herniation of brain downward. If there isn't this differential (communicating hydrocephalus), a spinal tap can decrease the pressure uniformly throught the CSF system.

What can be done for someone with craniostenosis to relieve increased intracranial pressure?

What can be done for someone with craniostenosis to relieve increased intracranial pressure?

Craniosynostosis =: premature fusion of one or more sutures, fibrous joints between the plates of bone in an infant's skull. Pediatric neurosurgeons perform minimally invasive surgery followed by helmet molding therapy for infants 3 months & younger. For older infants, they perform calvarial vault remodeling. Craniosynostosis is usually sporadic, but can occur in a variety of inheritable genetic syndromes.

Why is a person with increased intracranial pressure given the drug mannitol?

Why is a person with increased intracranial pressure given the drug mannitol?

Decrease pressure: Mannitol is used to manipulate osmotic (or oncotic) forces to shift water from the tissue into the blood vessels. In the kidney, mannitol increases water excretion. So, in patients with increased intracranial pressure, the intent is to decrease the pressure by using mannitol to "pull" fluid out of the brain and then excrete it via the kidneys.

Why is a person with increased intracranial pressure given the diuretic mannitol?

Why is a person with increased intracranial pressure given the diuretic mannitol?

Mannitol: Mannitol works to reduce intracranial pressure through its diuretic properties. It is usually used in the acute setting (after head trauma).

Why is it dangerous to do the lumbar puncture in a patient with increased intracranial pressure?

Can make it worse: Study of 30 patients with raised intracranial pressure whose condition worsened after lumbar puncture emphasizes the danger of carrying this out in the presence of raised intracranial pressure. In half the cases deterioration was immediate and dramatic, and in the other half it occurred within 12 hours.

How can you tell the difference between impeded blood flow (increased intracranial pressure) and sinus pressure?

How can you tell the difference between impeded blood flow (increased intracranial pressure) and sinus pressure?

Location: Increased intracranial pressure would be more generalized "headache" or pressure. I would expect there to be neurologic deficits as well: change in mentation, gait, speech, etc. Sinus pressure is located: maxillary - below eyes; ethmoid - between eyes; frontal - above eyes; sphenoid - on top of head or very back of head. Sinus pressure is usually very localized.

What are the symptoms of mild increased intracranial pressure?

What are the symptoms of mild increased intracranial pressure?

Mild????: There may be no symptoms of mild increased intracranial pressure. And how do you know it is mild? I'm not sure what mild increased intracranial pressure is because increased pressure is increased pressure. Increased pressure is not good. Symptoms may be headache, visual loss, dizziness, weakness, delerium, confusion, and many others.

What are the symptoms of increased intracranial pressure?

What are the symptoms of increased intracranial pressure?

Intracranial pressur: Individual with increased intracranial pressure usually complain of headaches and may have vomiting, blurred vision, and horizontal diplopia. The headaches are diffuse, worse at night, and often aggravated by sudden movement. Less common complaints include irritability, transitory visual obscurations, dizziness, and tinnitus.
