Q

Secondary Injury

A

hrs & days after the initial injury. due to lack of 02 & nutrients to cells. Due to cerebral edema, ischemia, seizures, infection, hyperthermia, hypovolemia & hypoxia

22
Q

How to get a contusion/bleed

A

direct trauma, shearing forces on arteries/veins,

23
Q

what determines s/s & time when symptoms occur with a contusion/bleed

A

site & rate of bleeding determines s/s & time when symptoms occur

24
Q

Epidural Intracranial bleed

A

bleed between dura & skull (burr holes are commonly used with this)

25
Q

Subdural intracranial bleed

A

between dura & arachnoid mater (brain); may be slow or fast

26
Q

Intracerebral intracranial bleed

A

in actual brain tissue ex. bullets or stab injury

27
Q

Burr holes are commonly used with which intracranial bleed?

A

Epidural and large acute subdural hematomas

28
Q

4 things you assess with Intracranial Bleed

A

1.)altered LOC 2.) changes in sensory or motor function 3.) pupil change 4.) vs changes

29
Q

Acceleration injury

A

The head is struck by a moving object

30
Q

Deceleration injury

A

when the head hits a stationary object

31
Q

Acceleration-deceleration (coup-countercoup phenomenon)

A

occurs when the head hits an object & the brain “rebounds” within the skull

32
Q

Penetrating Head injury

A

open brain injury; broken bones-youll see gray matter

33
Q

Closed head concussion (blunt)

A

a momentary interruption of brain function with or without loss of consciousness due to the blow to the head or a acceleration-deceleration injury

34
Q

Intracranial hemorrhage examples

A

Epidural, subdural, Intracerebral

35
Q

Skull fractures are classified as

A

open (dura is torn); closed (dura isnt torn) & 1)Liner 2)Comminuted/Depressed 3)Basilar

36
Q

Linear (Simple) Fractures, is dura intact? what can cause this?

A

most common, dura usually intact, subdural or epidural hematoma frequently underly the fracture

37
Q

Communited fractures

A

the bone is crushed into small fragmented pieces

38
Q

Depressed fractures

A

there is an inward depression of bone fragments

39
Q

with Communited/Depressed fractures is dura intact? what may be in brain tissue?

A

dura may or may not be intact, bone fragments may penetrate into the brain tissue

40
Q

Where do basilar fractures occur?

A

usually at the base of the skull, may involve the frontal sinus or temporal bone

41
Q

Manifestations of CSF leakage with Basilar fractures include

A

Rhinorrhea or otorrhea (test for glucose), “Halo” sign

42
Q

“Halo sign with basilar fractures

A

observe for blood tinged fluid, CSF dries in concentric rings on gauze or tissues

43
Q

Basilar fractures

A

if dura is disrupted, CSF may leak through tear; “Halo” & Battles sign may appear

44
Q

Battles sign with basilar fractures

A

seen several days after basilar fracture. there may be bloody drainage from ear right after fracture occured

45
Q

Craniotomy

A

part of skull is removed in order to evacuate chronic subdural hematomas

46
Q

Cushings response

A

when cerebral blood flow decreases significantly when brain is ischemic, it triggers an increase in arterial pressure to overcome the ICP

47
Q

Cushings Triad

A

brain trying to stabilize and fails; bradycardia, HTN, bradypnea

48
Q

3 s/s of cushings response

A

1)increase in systolic pressure 2)increase widing pulse pressure (S&D #s getting farther away) 3)bradycardia, bradyonea

49
Q

Brain stem function

A

automatic functions- heart rate,, breathing, swallowing, motor & sensory pathways

50
Q

Brain Stem consists of?

A

Mid-brain, Pons, Medulla oblongata

51
Q

Decorticate posturing & location

A

abnormal flexion of upper extremities; indicates damage to upper midbrain

52
Q

Decerebrate posturing & location

A

extreme extension of upper & lower extremities & indicates severe damage to brain @ lower midbrain & upper pons

53
Q

Locked in syndrome

A

a lesion affecting the pons or mid brain that causes tetraplegia & inability to speak
