Patient 1 – Two individuals come to the emergency department with head injuries. One is a 25 years old, has just been in a motor vehicle accident (MVA) and has a temporal lobe injury. The other, 65 years old, has increasing confusion after a fall that happened earlier in the week.

a. Differentiate the pathophysiology of extradural hematoma and subdural hematoma.
Extradural hematoma (Epidural hematoma): “Bleeding between the dura mater and the skull caused most commonly by motor vehicle accidents and occasionally by falls and sporting accidents”(McCance & Huether, 2014, p. 584). It usually results from a “brief linear contact force to the calvaria that cause separation of the periosteal dura from bone and disruption of interposed vessels due …show more content…

This patient most likely has a extradural (epidural) hematoma and the temporal fossa is the most common site of this type of hematoma caused by “injury to the middle meningeal artery or vein”(McCance & Huether, 2014, p. 584). “Expanding high-volume epidural hematomas can produce a midline shift and cause herniation of the brain. Compressed cerebral tissue can impinge on the third cranial nerve resulting in pupillary dilation and contralateral hemiparesis or extensor motor response”(Price, 2014, p. 3). Extradural hematomas are medical emergencies and surgical intervention is needed to remove the clot and reduce the pressure on the brain. Whether treated or untreated, this type of hematoma has an elevated risk of brain damage. However, left untreated, patients with extradural hematomas have a high risk of …show more content…

This “involves either the head striking a hard surface or a rapidly moving object striking the head. The dura mater remains intact and brain tissues are not exposed to the environment”(McCance & Huether, 2014, p. 582). Closed (blunt) trauma can be classified as primary (injury results from the initial anatomical and physiological insult usually direct trauma to the head) and secondary (results from hypotension, hypoxia, acidosis, edema, or factors that can secondarily damage brain tissue)(Rangel-Castilla, 2014, p. 2). It can also cause mild concussion (characterized by immediate but transitory clinical manifestations) and classic cerebral concussion (any loss consciousness accompanied by retrograde and anterograde amnesia)(McCance & Huether, 2014, p. 587). The degrees of concussions
