Diagnosis and Treatment
A person with a penetrating head injury may be evaluated using X-ray, CT scan, or MRI (however MRI can only be used when the penetrating object would not be magnetic, because MRI uses magnetism and could move the object, causing further injury).
Surgery may be required to debride or repair the injury or to relieve excessive intracranial pressure. Intracranial pressure is monitored and attempts are made to maintain it within normal ranges. Intravenous fluids are given and efforts are taken to maintain high blood oxygen levels.

Famous quotes containing the word treatment:
“James’s great gift, of course, was his ability to tell a plot in shimmering detail with such delicacy of treatment and such fine aloofness—that is, reluctance to engage in any direct grappling with what, in the play or story, had actually “taken place”Mthat his listeners often did not, in the end, know what had, to put it in another way, “gone on.””
—James Thurber (1894–1961)
