Which patient is at the highest risk for increased intracranial pressure (ICP)?

A patient with a traumatic brain injury is at the highest risk for increased intracranial pressure (ICP) due to the nature of the injury itself. Traumatic brain injuries can lead to edema, bleeding, or hematoma formation within the cranial cavity, all of which can significantly increase the volume and pressure inside the skull. The rigid structure of the skull allows for minimal expansion, meaning any increase in volume from swelling or bleeding will directly affect ICP.

In contrast, while severe hypotension can lead to various complications, it does not directly cause increased ICP. A patient who has recently had a myocardial infarction is typically monitored for heart-related complications and may not experience the direct effects on ICP that a brain injury would. Similarly, a patient post-operative from eye surgery may have specific considerations related to intraocular pressure rather than intracranial pressure. Hence, the direct association of brain trauma with potential increases in ICP makes this scenario the most critical in terms of risk.
