Q

Risk of wound infection: Anatomic location
* Head, neck=
* Upper extremity=
* Lower extremity=

A
  • Head, neck = low risk = Increased vascularity
  • Upper extremity = moderate risk.
  • Lower extremity = high risk = Decreased vascularity

Increased vascularity – low risk of infections due to higher oxygen and increased healing

Q

Risk of wound infectinon-Time of injury
* The sooner you close it =
* The longer you wait to close it, the higher what?
* Best to close it within what? Think twice if what? Worry about closing it if what?
* If you do close it late then what do you need to do?

A
  • The sooner you close it, the better.
  • The longer you wait to close it, the higher the risk of infection, so consider secondary intent.
  • Best to close it within 3 hours; Think twice about closing it over 6 hours; Worry about closing it if it’s >8-12 hours old
    * If you do, counsel patient and put in the chart

Q

wound preparation
* What type of technique?
* Anesthesia?
* What do you give? Where can you not place it?
* How do you stop blood?

A
  • Aseptic technique- no intent to introduce more germs on surface
  • Anesthesia: local or regional block
  • Lidocaine with epinephrine(vasoconstrictor): do not use on fingers, nose, penis, toes (or ears)
  • Hemostasis: direct pressure, epinephrine, Gelfoam, Surgicell, cautery, ligation, blood pressure cuff (brief) or glove with tip cut off

Frostbite
* What happens within cells?
* What complications?
* Patients are at risk of what?

A
  • Ice crystals ultimately form within cells
  • There are ischemic and vascular complications
  • Patients are at risk of reperfusion injury->Acidosis from the vasoconstriction and stasis
  • Ultimately there is necrosis demarcation and gangrene
    (tell them you don’t know how much damage there is).

Blood goes back to the core with metabolic acidosis. Crystals cause damage to cells. Don’t rewarnm if know they will be exposed to more cold and recrystallize the cells and cause more damage.

  • Injured extremity should be placed in gently circulating water that is 40 to 42 degrees centigrade (104-108 degrees F) for 10-30 minutes
  • Don’t forget pain medicine!
  • Probably should aspirate or debride clear blisters but not hemorrhagic blisters (will cause more damage)
    * Fluid contains inflammatory components—-further damage
  • Otherwise, watch and wait

  • Pen G – Prophylax against Streptococcal infection –> Consider MRSA coverage
  • Avoid early surgical debridement –> not until full demarcation (necrotic area and then normal area – no more damage will happen so go ahead and debride.
  • Some studies recommend tPa/Alteplase for thrombolysis following rewarming

Look for pulse, palpate for hardness, etc because one arm looks bigger

88
Q

Q

What are the complications of acute compartment syndrome?

A
  • Neurovascular injury
  • Infection

  • Myoglobinuric renal failure
94
Q

97
Q

Type of fracture:
* What is a typical fx?

  • Pathologic fracture – results from minor trauma to abnormal bone
  • Stress fracture – fatigue from repeated stress before bone & supporting tissues can recover (usually don’t show up on x-ray)/new bone(callous presumptive evidence)

If cant see fracture but you think they have it – splint them and re XR them in 7-10 days. New bone will form (Callous), then you can cast it.

98
Q

Salter-Harris fx:

Q

What is thompson test?

A

Thompson test can be used for assessing suspected achilles tendon ruptures. If there is no plantarflexion movement at the foot on squeezing the calf then a rupture is likely.

Lay prone and squeeze the calf. If tendon is interrupted – foot wont move.

Consider in any cancer patient w/ back pain until proven otherwise
* Pain first symptom & may occur months prior to neurologic dysfunction
* Weakness
* Sensory loss

Exacerbated w/ recumbency (lying down), improves w/ being upright

Loss of bowel & bladder (retention) control (usually a late finding)

161
Q

Malignant Spinal Cord Compression
* What is the most sensitive test?

A

MRI of whole spine

162
Q

Malignant Spinal Cord Compression
* What is the txt?

A

Tx: Corticosteroids
* Most common regimen: 10 mg bolus then 16 mg/day (divided over 4 doses)

Radiation therapy emergently
* Relieves pain in most patients
* Pre-treatment neurologic function is a strong predictor of response
* Underlying tumor type also predictor

Aggressive surgery
* New data shows that all patients should be considered for decompressive radical resection

163
Q

Discharge of Acute Trauma Injury
* Most will require what?
* Most will need acute script for what?
