hemorrhage and hematoma

Question 1

hemorrhage=

Answer 1

bleed

Question 2

hematoma=

Answer 2

blood clot

Question 3

hemorrhage and hematoma in brain can lead to

Answer 3

hypovolemia and hypovolemic shock

• loss of function of neural tissue in area
• loss of function at site of body that the area of brain controls

Question 4

intracerebral hematoma?

Answer 4

in the brain tissue (bleeding from a single or multi-vesses)

Question 5

epidural hematoma?

Answer 5

between skull and dura mater (outer meninge) in epidural space—-> bleeding from an artery d/t fracture of skull
-hematoma has no choice but to push against flexible dura mater and put pressure on brain tissue

Question 6

subdural hematoma?

Answer 6

between dura and arachnoid mater (outer and middle meninge), venous (slower than arterial, lose less blood short term)

• fibroblast activity causes hematoma to become encapsulated between the 2 meninges and traps the blood, where cell lysis occurs
• cellular efflux: fluid moves into the encapsulated area from surrounding subarachnoid space—> increased ICP
• dehydration of brain tissue occurs
• mass expands on exerts pressure on cranial contents
