Lecture 3: Ortho Wounds Flashcards
(165 cards)
Emergency Wound Management
* First what do you need to do?
First, assess the overall condition of the patient and take care of life-threatening injuries
How do you control bleeding?
As always, get a thorough history
* Can there be what?
* What type of water?
* What can be involve?
* What do you need to be worried about healing?
* Allergies?
* What type of status?
Risk of wound infection: Anatomic location
* Head, neck=
* Upper extremity=
* Lower extremity=
- 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
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?
- 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
Examining the wound
* When should you cover the wound?
* Assess what?
* Once this part of examine is done then what can you do?
* Always check for what?
* Remove what?
wound preparation
* What type of technique?
* Anesthesia?
* What do you give? Where can you not place it?
* How do you stop blood?
- 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
Explain where a digital block goes?
Explain where regional blocks go?
Radial nerve is lateral to artery
Lidocaine
* What are the types?
* Use what?
- 1% and 2%
- Also comes in 0.25% and 0.5%.
- Use lowest possible dose..
KNOW
Lidocaine
* What is the maximum adult dose? How do you figure out the dose?
* What is maximum child dose?
Maximum adult dose(toxicity=seizures)
* 4.5 mg/kg/dose; Do not repeat within 2 hours not to exceed 300mg/day.
Maximum child dose is probably 2-2.5 mg per POUND.
Wht is the acting and onset of lidocaine and bupivacaine
- Lidocaine: Short acting and fast onset
- Bupivacine: Long acting and long onset
KNOW
Percent (%) solution
* How do you figure out grams? mg?
KNOW
How many milligrams are in 1% of lidocaine
1%x10=10mg/cc
KNOW
- What is 10cc of 2.5% Bupivacaine?
- What is 5cc 4% topical procaine?
- 25mg/cc = 250mg of Bupivacaine
- 40mg/cc = 200mg of procaine
KNOW
Please calculate the maximum possible dose in milliliters per day of 5% lidocaine you could give to a 200kg person?
* 4.5ml
* 6ml
* 8ml
* 9ml
* 18ml
- 6ml
What are amides and esters? What do you give if patient is allergic to both?
Amides
* Two i’s
* Ex: Lidocaine
Esters:
* One i
* Ex. Procaine
Allergic to both: Liquid benadryl
What are the different topical anesthesia?
Wound preparation:
* What do you need to remove?
* What do you need to disinfect? What do you need to avoid?
* May do what to hair? Do not do what?
* NEVER do what?
- Foreign body removal ( explore )
- Skin disinfection
* Avoid Betadine or hydrogen peroxide (tissue toxic) - May cut hair (don’t shave it)
- Never remove eyebrow hair!
Wound Preparation
* Irrigate copiously with what?
* Debride what?
* What do you need to prophylactic with?
* Wound check when?
- Irrigate copiously with NS or tap water
- Debride devitalized tissue(minimum if possible)
- Prophylactic antibiotics (if indicated)
- Wound check in 24-48 hours
Prophylactic anx
* Human bites?
* Puncture wound thorugh rubber sole shoes/vibrio species?
- Human bites (dirtiest) in all locations and mammalian bites on hand = amoxicillin/clavulanic acid.
- Puncture wound through rubber sole shoes/vibrio species = Pseudomonas ( Fluoroquinolones- CIPRO)
Prophylactic Antibiotics Indications
* Full thickness oral laceration?
* Dog and cat bites?
* Contaminated wounds, or those with undetected FBs, may what?
What are the types of primary intent closure?
What are the different types of non-absorbable suture material
- Braided silk
- monofilament nylon (Ethilon)
- Monofilament polypropylene (Prolene)
