Nutritional deficiencies that affect wound healing
- Correct Answer - protein
carbs
fat
vitamin a
vitamin b
vitamin c
zinc
Meds that impair wound healing
- Correct Answer - steroids
anticoagulants
chemo
radiation
Protein (wound healing)
- Correct Answer - improves tissue integrity and collagen synthesis,
deficiency increases risk of evisceration
carbs and fat (wound healing)
- Correct Answer - energy source, prevent oxidation of amino acids
vitamin a (wound healing)
,- Correct Answer - accelerates healing of skin incision, collagen
production, and resistance to infection, deficiency decreases tensile
strength
vitamin b (wound healing)
- Correct Answer - necessary for carb metabolism
vitamin c (wound healing)
- Correct Answer - supports collagen formation, increases capillary
formation
zinc - Correct Answer - necessary for collagen synthesis and tissue
repair
steroids (wound healing)
- Correct Answer - suppress inflammation response, delay contraction
and collagen synthesis, chronic use decreases tensile strength, pt will
have debilitated immune response
anticoagulant (wound healing)
- Correct Answer - should be stopped 2-7 days before surgery
chemo (wound healing)
- Correct Answer - inhibit protein synthesis thus delaying wound repair
radiation (wound healing)
- Correct Answer - large dose decreases blood supply to area, may
affect healing and produce excess scarring
,Identify the nutritional component that supports collagen formation and
increases capillary formation
a) vitamin a
b) vitamin b
c) vitamin c
d) zinc
e) protein - Correct Answer - c
Passive/mechanical hemostatic agent (wound healing) - Correct Answer
- applied at bleeding site and provide barrier to stop blood flow (incl.
collagens, cellulose, gelatins, polysaccharide spheres)
active hemostatic agent (wound healing) - Correct Answer - contain
thrombin and products mixed with thrombin, enhance clotting at bleeding
site
ex. thrombin
flowable hemostatic agent (wound healing) - Correct Answer - combo of
passive and active agent, mechanically obstruct blood flow and convert
fibrinogen into fibrin at bleeding site
ex. floseal, surgiflo
fibrin sealants (wound healing) - Correct Answer - promote clotting by
increasing amount of fibrinogen and thrombin at bleeding site
ex. tisseel, tachosil, vitgel, coseal, duraseal, progel, bioglue, omnex
Collagen agent (mechanical hemostasis) - Correct Answer - avitene,
ultrafoam, helistat, helitene, instat
, Cellulose agent (mechanical hemostasis) - Correct Answer - surgicel,
nu-knit
gelatin agent (mechanical hemostasis) - Correct Answer - gelfoam,
surgifoam
polysaccharide sphere (mechanical hemostasis) - Correct Answer -
aristak, hemotase, vitsure
Identify the proper sequence of events in the body's defense mechanism
- Correct Answer - hemostasis --> cleaning up the pathogens --> wound
sealing --> regeneration of epidermal covering --> repairing deeper
tissue damage
Select the intraoperative factors that negatively affect wound healing:
a) surgical complication
b) failure to eliminate dead space
c) implantation of orthopedic hardware
d) incision in area of high mobility
e) incision in highly vascular area
f) use of x-ray - Correct Answer - a
b
c
d
Match the topical hemostatic with method of action
Agent:
1) passive
2) flowable
