Ce protocole s'adresse au patient comateux — score de l'Échelle de coma de Glasgow inférieur à 9 — présentant un hématome sous-dural aigu fin et un déplacement minime de la ligne médiane, chez qui la prise en charge initiale non chirurgicale avec surveillance de la pression intracrânienne n'a pas permis de maintenir la stabilité neurologique.

A comatose patient (GCS score less than 9) with an SDH less than 10-mm thick and a midline shift less than 5 mm should undergo surgical evacuation of the lesion if the GCS score decreased between the time of injury and hospital admission by 2 or more points on the GCS and/or the patient presents with asymmetric or fixed and dilated pupils and/or the ICP exceeds 20 mm Hg.
If surgical evacuation of an acute SDH in a comatose patient (GCS < 9) is indicated, it should be performed using a craniotomy with or without bone flap removal and duraplasty.
In patients with acute SDH and indications for surgery, surgical evacuation should be performed as soon as possible.
