what are the 5 Ps of compartment syndrome

Pulselessness
Paresthesias
paralysis
Pallor
pain

54

what is the most sensitive test for compartment syndrome?

passive stretch of the muscle w/i the compartment
patient should be in extreme pain

55

what are late findings of compartment syndrome

pulseless extremity
nerve deficit

56

what drugs can cause compartment syndrome in a relatively underwhelming fracture?

anti-coagulated patients
(plavix, coumadin, xarelto, ASA, etc)

57

what do you need to monitor head injury patients for?

DIC

58

what is the first sign of DIC

H&H good then plummets

59

Tx for compartment syndrome

fasciotomy
excision of necrotic tissue

60

how do you monitor compartment syndrome?

take pressure in compartment and compare to BP
