Which local anesthetic ia an amide prototype?

Lidocaine

2

Which local anesthetic is an ester prototype?

Procaine

3

Which local anesthetic should you NEVER deliver IV?

Bupivacaine - due to slow onset and long duration

4

Which size scalpel is used for I&D?

11

5

Which size scalpel is used most often for biopsy and excision?

15

6

Which size scalpel is used for areas of thick or tough skin?

10

7

What are the adverse effects of lidocaine systemically?

Drowsiness, heart block, arrhythmias

8

When you use forceps with and without teeth?

w/ - tissue handling
w/o - suture, foreign body, ok to crush

9

What is the formula for maximum dose of a local anesthetic?

(Pt wt x Max dose in mg/kg )/10

10

What is the max dose for lidocaine? w/ epinephrine?

3-4mg/kg
7mg/kg

11

Where is lidocaine metabolized?

Liver

12

Where is procaine metabolized? What is the metabolite?

Peripherally - plasma enzymes. PABA

13

10cc of a 1% solution of lidocaine contains how much lidocaine?

16

What is a sign of local anesthesia CARDIOVASCULAR TOXICITY?

Hypotension

17

What is the best treatment for a TOXIC reaction?

Oxygen

18

What suture type has the highest likelihood of tissue reaction?

Chromic gut

19

What would be indications for a non-absorbable deep suture?

Tendon repair

20

How are sutures sized?

As the number goes higher, suture becomes smaller (similar with IV catheters). Smallest suture 6-O

21

What type of suture is Nylon (absorbable/nonabsorbable, synthetic/natural)

Non Absorbable, synthetic

22

What are the four cardinal signs of purulent tenosynovitis?

Contraindications to I&D include...

Recurrent abscesses

24

Term: Destruction of all living microorganisms including bacterial spores

Sterilization

25

What is Universal Precaution?

Blood and body fluids of all patients should be considered potentially infectious, washing hands and sterilization, OSHA enforces

26

What type of suture provides less resistance as it passes through tissue and is least likely to harbor bacteria?

Monofilament - i.e. Nylon

27

Which intention: wounds too contaminated to close initially but may be closed after 3-4 days post tx

Tertiary intention

28

Term: disruption of blood vessels, extravasation of blood constituents, initiation of the coagulation cascade and formation of a fibrin clot

Hemostasis

29

Which intention: approximated wound that is sutured immediately

Primary intention

30

Which intention: unable to close wound, dehiscence, allowed to heal from the inside out

Secondary intention

31

This stitch is great for everting skin edges and precise approximation of wound edges with little tension.

Vertical mattress

32

The easy and most versatile stitch can cause "railroad track" scarring

Simple interrupted
