A rapid decline in serum levels of sodium leading to symptoms of increased intracranial pressure is a medical emergency, as further increases in braincell swelling can cause seizures, respiratory depression, coma, irreversible brain damage, or brain herniation
Cushing's triad [elevated systolic blood pressure with widening pulse pressure, bradycardia, altered respiratory rate and rhythm] represents late signs of increased intracranial pressure and may suggest imminent brain herniation
requiring immediate intervention [Fodstad, Kelly, & Buchfelder, 2006; Project TOUCH, 2001]).
According to Mosnier et al, in only 1 of 14 patients with prior mastoid surgery and brain herniation
through a tegmen defect was this fistula iatrogenic.
Lumbar puncture should be deferred in the presence of a brain lesion with mass effect to prevent brain herniation
Two blinded researchers categorized each patient's cause of death: Four of the five deaths in the dexamethasone group were attributed to brain herniation
or other neurologic causes; only one dexamethasonetreated patient died of a nonneurologic cause (including septic shock, respiratory failure, cardiac ischemia, and multiorgan failure).
Abstract: In a patient suffering from brain herniation
due to a right-sided subdural hematoma, a neurological examination should show left-sided deficits, known as localizing signs, and a decreased level of consciousness.
Certain clinical features and neurologic abnormalities can be used to determine which adult patients with suspected meningitis should undergo computed tomography of the head prior to lumbar puncture to assess risk for brain herniation
, the findings of a recent study suggest.
Certain synthetic biomaterials, such as Marlex mesh, have also been used to support the fascia in cases of brain herniation
7) MRI is superior to CT in defining brain herniation
