Trauma Flashcards

1
Q

Assessing for airway in the primary survey?

A

check for airway compromise

  • ask pt a qn
  • stridor
  • orofacial injury or burns
  • visualise airway and use suction if necessary

Q

what manouevres if pt is not breathing / airway obstructed?

A

Head tilt/ chin lift

Jaw thrust -> esp if potential c spine injury

Nasopharyngeal airway: in conscious pts as does not trigger gag reflex

oropharyngeal airway: prevents tongue from covering epiglottis

emergency airway: needle / surgical cricothyroidotomy

Definitive airway: endotracheal tube, tracheostomy

17
Q

mx of neurogenic shock?

A

Vasopressors: vasopressin and norad

Atropine: reverse the bradycardia

18
Q

what is spinal shock?

A

temporary reduction of or loss of reflexes following a spinal cord injury

loss of sensation accompanied by motor paralysis with initial loss but gradual recovery of reflexes

most commonly due to acute spinal cord transection (loss of reflexes but gradual recovery below level of transection)

19
Q

presentation of spinal shock?

A

areflexia

loss of sensation

hypotonic paralysis

bladder retention

20
Q

mx of massive haemothorax?

A

cross match 6 units

large bore chest drain

thoracotomy if > 1.5L or > 200ml/ h

21
Q

features of flail chest?

A

ant/ lat # of 2 or more adjacent ribs in 2 or more places

flail segment moves paradoxically w respiration

decreased oxygenation -> due to underlying pulmonary contusion, decreased ventilation of affected segment

22
Q

ix of flail chest?

A

CXR/ CT chest: pulmonary contusion

serial ABGs

23
Q

mx of flail chest?

A

O2

Good Analgesia*: PCA, epidural

positive pressure ventilation

24
Q

mx of rib #?

A

good analgesia:

NSAIDS + opioids

intrapleural analgesia

intercostal block

25
Q

mx of sternal #?

A

risk of mediastinal injury

analgesia, admit, observe

cardiac monitor

troponin: rule out myocardial contusion

26
Q

ix of pulmonary contusion?

A

CXR: opacification

Serial ABGs: decreased PaO2:FiO2 ratio

27
Q

mx of pulmonary contusion?

A

may -> ARDS

O2, ventilate if necessary

28
Q

Ix of myocardial contusion?

A

ECG: abnormal, arrhythmias

raised troponin

29
Q

mx of myocardial contusion?

A

bed rest, cardiac monitoring, tx arrhythmias

30
Q

ix of aortic disruption?

A

CXR: wide mediastinum

CT

31
Q

mx of aortic disruption?

A

cardiothoracics

32
Q

ix of oesophageal disruption?

A

CXR: pneumomediastinum, surgical emphysema

CT

33
Q

Ix in abdominal trauma?

A

urine dip: haematuria suggests injury to renal tract

FAST scan: check for fluid in abdomen, pelvis and pericardium

straight to laparatomy if unexplained shock, peritonism, intraperitoneal gas, gunshout wounds etc

34
Q

what is Kehr’s sign?

A

shoulder tip pain secondary to blood in peritoneal cavity

left Kehr sign is classic symptom of ruptured spleen

ie. in splenic rupture

35
Q

mx of urethral injury?

A

suprapubic catheter

surgical repair

36
Q

features of focal contusion?

A

e.g. coup and contra coup

may have focal neurological deficit

37
Q

diffuse axonal injury?

A

shearing forces disrupt axons

may -> coma and persistent vegetative state

autonomic dysfunction -> fever, HTN, sweating

38
Q

features of concussion?

A

temporary decrease in brain function

LOC, headache, confusion, visual symptoms, amnesia, nausea

39
Q

causes of secondary brain injury following head injury?

A

hypoxia

hypercapnia

hypotension

raised ICP

infection

40
Q

cushing reflex?

A

suggests raised ICP -> imminent herniation

hypertension

bradycardia

irregular breathing

41
Q

mx of raised ICP?

A

elevate bed

neuroprotective ventilation (normocapnoea)

mannitol or hypertonic saline

42
Q

Burns Wallace rule of 9s?

A

Head and neck: 9%

Arms: 9% each

Torso: 18% each for front and back

Legs: 18% each

perineum: 1%
(palm: 1%)
