Q

excessive scar formation:

  • cicatrix
  • keloid
  • proud flesh
A

CICATRIX- scar of healed wound (not so noticeable)

KELOID- healing complication, excessive collagen growth on wound

PROUD FLESH- over growth of granulation ( new connective tissue /blood vessels)

24
Q

Class I -clean

A

-elective procedure
surgical incision
-ideal conditions
- NO BREAK IN ASEPTIC TECHNIQUE

25
Class II -clean contaminated
- when entering mucus membrane like GI , GU tract, or respiratory tract - MINOR OR NO BREAK IN ASEPTIC TECH. - NO INFECTION PRESENT - may treat w/ antibiotics after procedure (surgeon will classify after surgery)
26
Class III- contaminated
- gross spillage from GI tract - MAJOR BREAK IN ASEPTIC TECH. - INFLAMMATION PRESENT - Open traumatic wound less than 4 HRS old - def will treat patient w/ antibiotics post surgery
27
Class IV- dirty or infected
- perforated viscera (organ) --ex. rupture in appendix - dirty traumatic wound over 4-6 hrs OR foreign body present in wound - BACTERIA PRESENT IN WOUND BEFORE SURGERY - INFECTION W/ DRAINAGE
28
debridement
removing dead tissue, scraping it away
29
fistula
a tract between 2 epithelium- lined surfaces that is opened at both ends
30
SUTURES: | monofliment
single continuous fiber - good healing properties - relatively inert - minimal tissue damage - NOT as easy to work with
31
multifilament suture
multiple thread like structures(twisted or braided) into single strand - absorbs moisture and hold body fluid b/c of capillary action(WICKING) - HARBOR BACTERIA - NOT USED IN PRESENCE OF INFECTION - EASY to work with
32
1. absorbable suture | 2. non- absorbable suture
absorbable- able to be absorbed by tissue via hydrolysis (fluid breaks down suture) -designed to hold tissue edges together until they heal non-absorbable- resists absorption by tissue -get encapsulated by tissue
33
natural absorbable sutures
* SURGICAL GUT - from submucosa of sheep intestine - MONOFILAMENT - PACKED IN ALC *PLAIN GUT * CHROMIC GUT--> processed with salts to extend lifespan--> used primarily for urinary tracts - absorbs fastest CAT GUT--> collagen from animal intestine (multi)
34
Synthetic absorbable sutures
DEXON PDS MONOCRYL VICRYL - can be mono or multifilament - wound support for 3 weeks to 6 months - inert - absorbed by HYDROLYSIS
35
natural non-absorbable sutures
SILK --> multi , high wicking action STAINLESS STEEL--> strongest suture, most inert, special handling
36
Synthetic NON- absorbable sutures
NYLON- mono - skin suture - minimal tissue reaction NUROLON- multifilament nylon - used to close dura (on brain) or meninges POLYPROPYLENE-PROLENE- mono -inert
37
SUTURIING TECHNIQUES: * primary suture line
- continuous. suture/ running suture - interrupted suture Mattress suture
38
subcuticular suture
used for cosmetic closure | -cant see on the dermal layer
39
purse string suture
pulled through like a drawstring | -used for intestines or appendix removal, appendectomy
40
Secondary suture line: retention suture/stay suture
large gauged, non absorbable - bolsters, bridges or bumpers (plastic or rubber tubing) - -threaded over retention suture ends prior to tying*
41
anastamosis
reconnection of 2 structures
42
traction sutures
structures put in place to keep wound open instead of using retractor --used for HEART & BRAIN
43
synthetic adhesives-- DERMABOND
a glue in the wound that seals skin closed
44
pressure dressing
a bunch of DRESSING sponges on top of wound to prevent bleeding & dead space( fluid accumulation)
45
ligatures
used to tie off bleeding vessels suture ligature stick tie continuous ligature reel free tie --> pre cut, single strands in package tie on pass -->loaded onto a curved clamp to tie to help placement of tie around vessel in deep surgical wound
46
types of needles
keith -- straight needle curved -- most commonly used eyed -- french eye, mayo
47
parts of needle
POINT, BODY, EYE
48
needle points
Cutting- used for SKIN, Cartilage, Tendons (cuts through tissue also) Taper- just the point is sharp, doesn't cut tissue around area, used for delicate, fine tissue like INTESTINE Blunt- not very sharp, rounded blunt point,, used for organ structures that bleed a lot, like KINDEY, SPLEEN, LIVER
49
Swaged needles
single armed or double armed | - 1 needle on end or 1 needle on each end (2 total)
50
swaged contd. control release
when you can pull needle off of suture
51
swaged contd. permanently swagged
you need scissors to cut needle off of suture
52
tapered needle
round body, tapers to sharp point | -primary use is for soft tissue
53
spatula needle
side cutting needles, slat on top &bottom | -used for ophthalmic surgery, eyes, extremely thin layers of tissue like cornea etc
54
what type of wound that is expected to heal by 1st intention?
a clean wound
55
which class of surgical wound is considered dirty or infected?
class IV
56
when the wound is left open and allowed to heal from inner layer to outside surface is considered what type pf healing?
granulation... 2nd intention
57
which phase of wound healing begins within minutes of injury ?
lag phase
58
what is the suture diameter referred to as ?
gauge
59
what suture is most likely used for orthapedic wounds and abdominal fascia?
#1
