The primary goal of treatment for patients with suspected TBI's is to prevent ___________________________________________. - Secondary Brain injury The most important ways to limit secondary brain damage and thereby improve a patients outcome are to - Ensure adequate oxygenation and maintain blood pressure at the level that is sufficient to perfuse the brain. Skull Anterior Fossa - Houses ?????? Middle Fossa - Houses ????? Posterior Fossa - houses ????? - Anterior Fossa - Houses the frontal lobes Middle Fossa - Houses the temporal lobes Posterior Fossa - contains the lower brain stem and cerebellum Meninges ___________________________________ is a tough fibrous membrane that adheres firmly to the internal surface of the skull, at specific sites, the ________________ splits into two "leaves" that enclose the large venous sinuses, which provide the major venous drainage from the brain. - Dura Mater / Dura. ______________________________________ lie between the dura and the internal surface of the skull in the epidural space. Overlying skull fractures can lacerate these arteries and cause an epidural hematoma. - Meningeal arteries The _____________________________________ is the most common injured artery, located over the temporal fossa. - The middle meningeal artery __________________________________________ space between the dura mater and the arachnoid mater - Subdural spaceBeneath the dura is a second meningeal layer: the thin, transparent arachnoid mater. Because the dura is not attached to the underlying arachnoid membranes a potential space between these layers exists (the subdural space) into which hemorrhage can occur. - In a Brian injury, bridging veins that travel from the surface of the brain to the venous sinuses within the dura may tear, leading to the formation of a subdural hematoma. ______________________________________ is firmly attached to the surface of the brain. Cerebral spinal fluid fills the space between the watertight arachnoid mater and the pia mater. (Subarachnoid space) Hemorrhage into this fluid filled space frequently accompanies brain contusion and injuries to major blood vessels at the base of the brain. - Pia Mater
