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. ...Read more

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. ...Read more

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. ...Read more

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. ...Read more
