Flashcards in Minor Surgery Deck (50):
Which local anesthetic ia an amide prototype?
Which local anesthetic is an ester prototype?
Which local anesthetic should you NEVER deliver IV?
Bupivacaine - due to slow onset and long duration
Which size scalpel is used for I&D?
Which size scalpel is used most often for biopsy and excision?
Which size scalpel is used for areas of thick or tough skin?
What are the adverse effects of lidocaine systemically?
Drowsiness, heart block, arrhythmias
When you use forceps with and without teeth?
w/ - tissue handling
w/o - suture, foreign body, ok to crush
What is the formula for maximum dose of a local anesthetic?
(Pt wt x Max dose in mg/kg )/10
What is the max dose for lidocaine? w/ epinephrine?
Where is lidocaine metabolized?
Where is procaine metabolized? What is the metabolite?
Peripherally - plasma enzymes. PABA
10cc of a 1% solution of lidocaine contains how much lidocaine?
1cc of a 1% lidocaine solution contains how much lidocaine?
When would you avoid using epinephrine?
Distal procedures - ears, nose, fingers, toes, clit, penis
What is a sign of local anesthesia CARDIOVASCULAR TOXICITY?
What is the best treatment for a TOXIC reaction?
What suture type has the highest likelihood of tissue reaction?
What would be indications for a non-absorbable deep suture?
How are sutures sized?
As the number goes higher, suture becomes smaller (similar with IV catheters). Smallest suture 6-O
What type of suture is Nylon (absorbable/nonabsorbable, synthetic/natural)
Non Absorbable, synthetic
What are the four cardinal signs of purulent tenosynovitis?
1) Slight finger flexion 2)Fusiform swelling of the finger
3)Pain on passive or active extension of the finger
4)Tenderness along the tendon sheath into the palm
Contraindications to I&D include...
Term: Destruction of all living microorganisms including bacterial spores
What is Universal Precaution?
Blood and body fluids of all patients should be considered potentially infectious, washing hands and sterilization, OSHA enforces
What type of suture provides less resistance as it passes through tissue and is least likely to harbor bacteria?
Monofilament - i.e. Nylon
Which intention: wounds too contaminated to close initially but may be closed after 3-4 days post tx
Term: disruption of blood vessels, extravasation of blood constituents, initiation of the coagulation cascade and formation of a fibrin clot
Which intention: approximated wound that is sutured immediately
Which intention: unable to close wound, dehiscence, allowed to heal from the inside out
This stitch is great for everting skin edges and precise approximation of wound edges with little tension.
The easy and most versatile stitch can cause "railroad track" scarring
Urea paste dissolution and antifungal oral medications are appropriate treatments for what condition?
What type of cyst can be treated by simple rupture by pressure, simple aspiration, or surgical excision?
Ganglion cyst - an aneurysm in the tendon sheath that tend to recur
This stitch is used for triangular flaps.
This stitch is placed in the dermis and is not visible. It works best in wounds where there is minimal tension and a clean, linear wound.
What nutrient/enzyme is known to promote wound healing?
Most common organism to cause wound infections.
What type of suture is steel (absorbable/non absorbable, braided/monofilament)
Non absorbable, monofilament
Poor hemostasis can cause what to form?
This regional nerve block is useful for providing anesthesia to the tip fo the little finger.
This regional nerve block is injected into the anatomical snuff box to provide anesthesia to the lateral aspect of the proximal thumb.
For the trunk, legs, feet or scalp, use the following type (size) of suture and remove after how many days?
3-O, 7-14 days
Is cryotherapy indicated for cervical warts?
Yes. NOT for melanoma, SCC, and BCC
T/F: Electrocautery is indicated for actinic keratoses.
Elliptical excisions should have a length to width ratio of _____ with corners at ___ degree angles.
Elliptical excisions should ideally be made with a # ____ blade, initially cutting ____ to the skin.
Most dangerous skin tumor
Indicated treatment for infections that result in a collection of purulent material in a circumscribed and closed cavity.
