Flashcards in Neuro K Coma Deck (19):
1

Coma anatomy

Dysfunction of both hemispheres or the Reticular Activating System

2

Persistent Vegitative State definition

Complete lack of awareness, but preservation of some autonomic function (brainstem)

3

#1 reason for seizure recurrence

Noncompliance

4

Coma history -> Cause
1. Sudden Onset
2. Hemiparesis
3. Protracted downhill course
4. Preceded by confusion

1. Brainstem stroke, subarachnoid hemorrhage
2. Intracerebral hemorrhage
3. Tumor, Abscess, Chronic Subdural
4. Metabolic, Drugs

5

Cranial nerve exit mnemonic

2244
2- above brainstem
2- midbrain
4- pons
4- medulla

6

Pupillary constriction

CN 3 Midbrain

7

Vestibular system

CN 8 Pons

8

Pons lesion pupils

Pinpoint (para fine, sympa destroyed)

9

Midbrain lesion pupils

Midposition, fixed

10

Coma nystagmus

Slow deviation, no nystagmus (no frontal lobe)

11

COWS

Opposite for comatose (mnemonic is for nystagmus, not deviation)

12

Shotgun Tx for ER coma

Glucose, Thiamine, Naloxone

13

Glasgow Coma Scale - 3 Measurements

2. Verbal
3. Motor

14

Coma time length

4 weeks max

15

Definition of death

Cessation of brain function

16

Coma definition

Not responsive, but some brainstem reflexes

17

3 Findings of Brain Death

1. Coma
2. Absence of Brainstem reflexes
3. Apnea

18

Positive apnea test
