Ch. 11 The post-op patient Flashcards
What is the recovery period?
From cessation of anesthesia to P return of normal vital signs and consciousness
What is stage 1 if heat loss
transferred from core to the skin
What is stage 2 of heat loss
lost to the environment by conduction, convection, radiation, evaporation
When should you consider rewarming a patient?
97.6F
Rewarming techniques
-Passive external (blankets)
-active external (warming devices)

What is a seroma
-serum collects b/w skin and muscle
-typically due to excessive movement
-potential abscess formation
Dx of a seroma
-aspiration
-differential via Diff-Quik type stain
Tx of seromas
-warm, most compresses

-possibly sx drain
What is loss of sutures allowing sx site to open
postoperative dehiscence
Risks of postop dehiscence
contamination, serious potentially fatal
Causes of postop dehiscence

-infection
-blunt trauma
What does sx site infection look like
swollen, red, draining
What does infection at sx site cause
delayed healing
Tx of sx site infection
-possible sx debridement and restoring
-systemic antibiotics
