Intracranial Pressure Monitoring: Invasive versus Non-Invasive Methods-A Review
TLDR
An overview of the advantages and disadvantages of the most common and well-known methods as well as whether noninvasive techniques can be used as reliable alternatives to the invasive techniques is provided.Abstract:
Monitoring of intracranial pressure (ICP) has been used for decades in the fields of neurosurgery and neurology. There are multiple techniques: invasive as well as noninvasive. This paper aims to provide an overview of the advantages and disadvantages of the most common and well-known methods as well as assess whether noninvasive techniques (transcranial Doppler, tympanic membrane displacement, optic nerve sheath diameter, CT scan/MRI and fundoscopy) can be used as reliable alternatives to the invasive techniques (ventriculostomy and microtransducers). Ventriculostomy is considered the gold standard in terms of accurate measurement of pressure, although microtransducers generally are just as accurate. Both invasive techniques are associated with a minor risk of complications such as hemorrhage and infection. Furthermore, zero drift is a problem with selected microtransducers. The non-invasive techniques are without the invasive methods' risk of complication, but fail to measure ICP accurately enough to be used as routine alternatives to invasive measurement. We conclude that invasive measurement is currently the only option for accurate measurement of ICP.read more

TL;DR: It is proposed that vigorous surgical and medical therapy, by preventing or reversing secondary cerebral insults, enables some patients who would have died to make a good recovery without increasing the proportion of severely disabled patients.

TL;DR: The Monro–Kellie doctrine, or hypothesis, is that the sum of volumes of brain, CSF, and intracranial blood is constant and an increase in one should cause a decrease in one or both of the remaining two.
