Flashcards in Evaluation, resuscitation, and DCO Deck (12):
1

Use of an airbag in a head on collision is a/w a decrease in?

1) closed head injuries
2) facial fractures
3) thoracoabdominal injuries
4) need for extraction

2

What % of preventable deaths occur in the 'Golden Hour'?

60%; period of time when life threating and limb threatening injuries should be treated in order to decrease mortality
Three peak times of death after trauma
1) 50% within the first minutes of sustaining the injury
caused by massive blood loss or neurologic injury
2) 30% within the first few days
most commonly from neurologic injury
3) 20% within days to weeks following injury
multi system organ failure and infection are leading causes

3

What special consideration should be given during the ABC phase in pregnant women who have sustained trauma?

Placing them in a left lateral decubitus position

4

What % blood loss is reflected by an increase in heart rate?

15-30%

5

What % blood loss is reflected by a decrease in SBP?

30-40%

6

What are indicators of adequate resuscitation?

1) MAP > 60
2) HR 7.3
4) UOP 30cc/hr
5) Lactate

7

What is the the key variable to differentiate septic shock and hypovolemic shock?

SVR is increased in hypovolemic shock
CO and CVP are decreased in both

8

What is the most common cause of delay in fracture diagnosis?

Failure to image extremity

9

What are the trauma series x-rays?

AP chest, AP pelvis, Lateral c-spine (must see C7 on T1)
CT pelvis should be delayed until preliminary fixation with sheet binder or ex-fix

10

What factor has been shown to increase mortality in poly-trauma patients with severe head injuries?

Intra-operative hypotension

11

What parameters can help decide on patients that need to be treated with damage control orthopedics?

1) ISS >40 (without thoracic trauma)
2) ISS >20 with thoracic trauma
3) multiple injuries with severe pelvic/abdominal trauma and hemorrhagic shock
4) bilateral femoral fractures
5) pulmonary contusion noted on radiographs
6) hypothermia

12

Patients are at increased risk of ARDS during the 2-5 day "inflammatory window", what life-threatening injuries should be treated in this window?

1) compartment syndrome
2) fractures with vascular injuries
3) unreduced dislocations
4) long bone fractures
5) unstable spine fractures
6) open fractures
