Q

Occurs with pressure in the compartment exceeds that of the capillary (30mmHg), pressure increases and subsequently can lead to impaired blood flow

A

Compartment syndrome

17
Q

Paresthesia’s (most common)

Pain (most common) pain often described as out of proportion

Pulselessness – uncommon, late finding

Pallor

Paralysis

A

Compartment syndrome

18
Q

Intervention used in the treatment for compartment syndrome

A

Fasciotomy

19
Q

The avulsion of skin from the underlying structures is usually a result of trauma

20

21
Q

Most common causes of degloving

A

Road traffic accidents

Conveyor belt injuries

Ring avulsion injuries

22
Q

Degloving occurs at which skin level?

A

Subcutaneous

23
Q

Field management for degloving injuries

A

Irrigate and clean wound

Antibiotics to cover skin flora (staph & strep)

  • Cefazolin
  • Augmentin
  • Doxycycline
  • Ciprofloxacin
  • Ertapenem
24
Q

Majority of pelvic fractures are due to:

A

High energy blunt trauma

25
Pelvic fracture Life threatening hemorrhage is typically from:
Venous plexus
26
Most common vertebrae affected with pelvic ring fracture
L5 & S1
27
Bony pelvis consists of:
Sacrum Coccyx 3 innominate bones (ilium, ischium, pubis)
28
Forms together to form the acetabulum
Ilium Ischium Pubis
29
Pelvic fracture types
Pelvic ring Lateral compression Anterior posterior Vertical shear Open book
30
Common term to describe pelvic ring disruptions. Widening of symphysis pubis or rami fractures, and posterior ligamentous injury.
Open book
31
When the anterior pelvic ring widens more than ___ cm, the posterior pelvis (especially the anterior portion of the sacroiliac ligamentous complex) is frequently injured, increasing the risk of hemorrhage.
2.5
32
This reduces pelvic volume and stabilizes fracture fragments, thereby reducing the risk of major hemorrhage
Pelvic binder
33
Gold standard in identifying pelvic fractures
CT scan
34
Landmark for pelvic binder
Greater trochanter
