Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.

However, there are many factors that can complicate placement of a peripheral intravenous cannula (PIV), and it is extremely common for PIV attempts to fail. PIV placement may be technically challenging in small...

Detection of Black Holes

Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s. Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light. Not until the 1960s, when the first neutron...
FAQs
Placement depends on matching the intended intracranial target with anatomical landmarks and imaging findings. These references help the surgeon select an entry site for accessing tissue, a fluid collection, or a monitoring location. Accurate localization matters because the opening must support the planned intervention while limiting unnecessary disruption to surrounding tissues.
The skull is only one layer along the access path, so drilling requires control beyond creating the bony opening. The procedure specifically includes protecting the dura and underlying brain while the specialized drill penetrates the skull. This protection helps preserve the intended access route and reduces the risk of avoidable tissue disruption during intracranial work.
The opening can serve different purposes depending on the planned intervention. It may be covered when access is complete, left available for drainage, or used to place a catheter. This choice connects the initial skull opening to the clinical goal, whether that goal involves accessing intracranial tissue, removing or managing fluid, or monitoring an intracranial site.
Success depends on accurate target selection, controlled drilling, and alignment between the opening and the intended use. Anatomical landmarks and imaging support localization, while protection of the dura and brain limits tissue disruption. The final configuration also matters, because covering the opening, permitting drainage, or placing a catheter must match the required neurosurgical intervention.
In neuroscience, this approach supports treatment of conditions including subdural hematoma and hydrocephalus. It also provides access for intracranial pressure monitoring and for selected diagnostic or therapeutic procedures. These applications use the opening either to address abnormal fluid, establish a monitoring site, or reach intracranial structures relevant to evaluation and treatment.
A burr hole can provide access to intracranial tissues, fluid collections, or monitoring sites, so its value is not limited to one disease or intervention. In research and clinical neuroscience, the selected access point can support diagnostic assessment, therapeutic work, or measurement of intracranial pressure. The outcome depends on accurate placement and the procedure that follows.
