Trauma - Musculoskeletal Flashcards
1
Q
femur fracture
A
- 1,500 mL blood loss
- early stabilization (<24 hours)
2
Q
fat embolism syndrome timeline
A
12-72 hours after injury
3
Q
fat embolism syndrome s/s
A
- hypoxia
- tachycardia
- AMS
- petechial rash
- elevated PAP
- decreased CO
4
Q
fat embolism syndrome treatment
A
- supportive
- early surgery

5
Q
largest concern in pelvic fracture
A
-bleeding (*retroperitoneal)
6
Q
neuraxial anesthesia in pelvic fracture?
A
NO: coagulopathy and high chance of pre-existing neuronal injury
7
Q
hip dislocation
A
- orthopedic emergency: avascular necrosis of femoral head
- anesthesia: deep sedation versus muscle relaxants
8
