Q

When does an abscess warrant caution?

A
  • Abscess from IVDA (“shooters abscess”)

Q

Treatment of simple/small abscess

A
  • Warm compress to allow spontaneous drainage
  • Abx NOT necessary once draining
  • If it enlarges, it can encapsulate which will render abx ineffective
  • I&D, wound culture

Q

When are abx warranted after I&D?

Study These Flashcards
A

If local cellulitis present

20
Q

Where should you incise during an I&D?

Study These Flashcards
A

Along Langer lines

21
Q

What should an I&D abscess be packed with?

Study These Flashcards
A

Iodoform gauze

22
Q

Healing of an I&D abscess progresses in what way?

Study These Flashcards
A

Inside out - so pack it well and full enough

23
Q

If abscess needs longer time to heal, what can be done during I&D?

Study These Flashcards
A

Use criss cross (cruciate) incision

24
Q

Aftercare of an abscess I&D

Study These Flashcards
A
  • Pain control
  • Schedule FU
  • Apply warm wet compresses
  • Non adherent bulky dressing w/daily changes
  • Immobilize cellulitis
  • RICE
  • Abx are guided by wound cultures and risks
  • Refer to surgeon when appropriate
25
Common site of ingrown toenail
Medial or lateral great nails
26
MC cause of ingrown toenail
Improper fitting shoes or trimming of nails
27
Relative contraindications of treating ingrown toenail
- Bleeding issues - CAINE allergies - PVD - Pregnancy (phenol to ablate matrix is contraindicated)
28
What is onychogryposis?
Congenital curved toenail causing increased risk of ingrown toenail
29
Complications of ingrown toenail
- Infection | - Nail will regrow if not ablated properly using cautery or 10% phenol
30
Follow up care of ingrown toenail
- Elevation 24-36 hrs w/gradual return to walking - OTC pain control - Dressing changes in 24 hrs - Soak toe in warm water twice daily for several days after first dressing change
31
What may occur if pressure of a subungual hematoma is not relieved?
Damage to nail matrix and germinal layer
32
Contraindications to subungual hematoma drainage
- Crushed or fractured nails - Tuft fracture - Suspicious lesion under nail - Pt wearing acrylic nails - Over 50% of nail could indicate nail bed laceration (controversy over whether to remove or not)
33
Complications of subungual hematoma
- Nail deformity - Infection - Cautery can cause burn to nail bed (if not used properly) - Numbness (RARE)
34
How to grasp tick during removal?
- Grasp at skin level tugging up steadily - DO NOT TWIST - Do not grab tick by body or could expel the contents into patient
35
What of the tick will transmit disease?
Head NOT mandible - if the mandible is imbedded it can stay in, it won't transmit disease
36
Treatment for early Lyme disease
Doxy
37
How should a fish hook wound be prepped for removal?
- Cleanse hook and puncture wound with povidone-iodine or another abx solution - Provide tetanus prophylaxis as needed
38
How should superficial fish hook removal be attempted?
"Retrograde" technique - push hook back along entrance while applying gentle downward pressure on shank
39
How should a fish hook be removed if it cannot be taken out using retrograde technique?
18 gauge needle inserted into puncture hole and used as a mini scalpel blade - manipulate hook into a position so you can cut the bands of connective tissue caught over barb and release it
40
How should deeply imbedded fish hooks be removed?
- "Needling" the hook - #18 or 20 hypodermic needle through wound alongside hook - Blindly slide needle opening over barb of hook and lock 2 together - With barb covered, remove hook and needle as 1 unit
41
What does "needling" a fish hook for removal require?
Greater skill but allows you to work on an unstable skin surface like finger or ear
42
When unable to try other techniques including "needling", how can fish hooks be removed?
"Push through" maneuver - then cut off tip of hook and remove shaft
43
How to remove a multifaceted (treble) hook?
Cover free hooks with corks or use a pin cutter to remove free hooks
44
DON'Ts of fish hook removal
- Do not try to remove multifaceted hook w/o first covering free hooks or removing them - Do not attempt "string" technique if hook is near patient's eye - Do not routinely prescribe proph abx (infection is rare)
45
Prophylactic abx for fish hook removal?
Do NOT routinely prescribe - even hooks contaminated by fish rarely cause secondary infection
