Medication Summary

Although significant acute traumatic subdural hematoma requires surgical treatment, temporizing medical maneuvers can be preoperatively used to decrease intracranial pressure. Short-acting sedatives and paralytics should be used only when needed to facilitate adequate ventilation or when elevated intracranial pressure is suspected. If the patient exhibits signs of a herniation syndrome, administer mannitol 1 g/kg rapidly by intravenous (IV) push.

Class Summary

These agents may help reduce intracranial pressure.

Mannitol (Osmitrol)

 

Mannitol may reduce subarachnoid space pressure by creating an osmotic gradient between the cerebrospinal fluid in the arachnoid space and the plasma. It is not for long-term use. Initially assess for adequate renal function in adults by administering a test dose of 200 mg/kg, given IV over 3-5 min; this should produce urine flow of at least 30-50 mL/h of urine over 2-3 hours.

Acute right-sided subdural hematoma associated with significant midline shift (ie, subfalcine herniation) shown on CT scan.
Bilateral chronic subdural hematomas shown on CT scan. Midline shift is absent because of bilateral mass effect. Subdural hematoma is bilateral in 20% of patients with chronic subdural hematoma.
An acute subdural hematoma is shown in this intraoperative photograph. Note the frontotemporoparietal flap used. The hematoma is currant jelly–like in appearance.
A left-sided acute subdural hematoma (SDH). Note the high signal density of acute blood and the (mild) midline shift of the ventricles.
A left-sided chronic subdural hematoma (SDH). Note the effacement of the left lateral ventricle.
Chronic subdural hematomas (SDHs) are commonly bilateral and have areas of acute bleeding, which result in heterogeneous densities. Note the lack of midline shift due to the presence of bilateral hematomas.
An isodense subdural hematoma (SDH). Note that no sulcal markings are below the inner table of the skull on the right side. This hematoma has scattered areas of hyperdense, or acute, blood within it.
Isodense subdural hematoma (SDH) as pictured with MRI. MRI can more readily reveal smaller SDHs, and, on MRI, the imaging of the blood products change characteristically over time.
Atrophy of the brain, resulting in a space between the brain surface and the skull, increases the risk of subdural hematoma (SDH).
An acute subdural hematoma (SDH) as a complication of a craniotomy. Note the significant mass effect with midline shift.
Acute subdural hematoma. Note the bright (white) image properties of the blood on this noncontrast cranial CT scan. Note also the midline shift. Image courtesy of J. Stephen Huff, MD
Subacute subdural hematoma. The crescent-shaped clot is less white than on CT scan of acute subdural hematoma. In spite of the large clot volume, this patient was awake and ambulatory. Image courtesy of J. Stephen Huff, MD.
