Ch11 Wounds

Wound Healing

INFECTION microbial contamination overriding the resistance of the host
THERMAL heat or cold
TENSILE STRENGTH ability to resist rupture
FISTULA a tract between two epithelium-lined surfaces that is opened at both ends
KELOID SCAR a hpertropic scar formation
MONOFILAMENT suture material made of a single threadlike structure
INCISION internal cut
HEMORRAGE excessive or profuse bleeding
SINUS TRACT a tract between two epithelium lined surfaces that is open only at one end
MULTIFILAMENT suture material consisting of multiple tread like structure
LACERATION cut or tear
CICATRIX mature surface scar
WOUND tissue that has been damaged
FRIABLE easily torn tissue
PUNCTURE penetrating wound
ADHESION abnormal attatchment of two surfaces or structures that are normally separated
POLYPROPYLENE MESH a relatively inert material that can be used in the presence of infection
GROUND POINT WIRE NEEDLE has a point with sharp edges, but the round body of a tapered needle
STAINLESS STEEL MESH a material that is rigid and hard to apply, resulting in discomfort for the patient
TAPERED POINT NEEDLE has a round shaft without a cutting edge, penetrates tissue without cutting it
REVERSE CUTTING NEEDLE consists of opposing cutting edges that extend to the full length of the shaft
LINEAR CUTTER delivers double line of staples, the blades pass between to divide tissue
POLYTETRAFLUOROETHYLENE MESH soft, flexible material, not absorbable, not used in the presence of infection
LIGATION CLIP used to occlude a single small suture, such as a vessel or duct
CONTROL RELEASE NEEDLE a needle that pops of the suture strand by tugging
LINEAR STAPLER inserts two straight, staggered, evenly spaced, parallel rows fo staples
INTRALUMINAL STAPLE fires double rows of staples with a knife located within the head used for trimming
SIDE CUTTING NEEDLE used mainly for opthalmic procedures, as they dont penetrate deeper tissue
TROCAR POINTS has three sharp cutting edges that end in a sharp cutting tip
LIGATING CUTTER ejects two ligating clips dividing tissue between clips with single activation
POLYESTER FIBER MESH least inert of synthetic meshes; should never be used in presence of infection
POLYGLACTIN 910 MESH an absorbable material that provides temporary support during healing
CONVENTIONAL CURRING NEEDLE consists of three cutting edges, directed along the inner curve of the needle
BLUNT POINTS have round shaft that end in a blunt tip
CLOSED EYE NEEDLE round or square hole, loaded by inserting suture material through the hole
FRENCH EYE NEEDLE loaded by pulling the taut strand into a V-shaped area just above the eye
Which layer is typically not closed with suture? Does not tolerate suture material well? MUSCLE
Best needle for suturing skin... REVERSE CUTTING
Exposure of visera through the edges of a totally separated wound EVISCERATION
Skin staples are _____ reactive to the human body, when compared to plain gut suture LESS
_______ would be used to tie off deep bleeding vessels that have been occluded with a hemostat clamp TIE-ON-A-PASS
A suture packet that is beige in color is CHROMIC GUT
Which phase of wound healing begins within minutes of injury and is manifested by heat, redness, swelling, pain, and loss of function? LAG
Abnormal attachment of two surfaces or structures that are normally separated ADHESION
Pathological, surgical, or traumatic formation of an opening between two normally seprated organs or spaces ANASTOMOSIS
Returned to proximity; brought together sides or edges APPROXIMATED
A suture material manufactured from the submucosa of sheep intestine or serosa of beef intestine treated with chromium salts to delay the rate of absorption CHROMIC GUT
Wound that persists for an extended period of time CHRONIC WOUND
A space that remains in the tissues as a result of failure of proper closure of a surgical wound DEAD SPACE
Removal of devitalized tissue and contaminants DEBRIDEMENT
Partial or total separtion of a layer or layers of tissue after closure of a wound DEHISCENCE
Interuption of a closed wound or traumatic injury that exposes the viscera EVISCERATION
Type of healing that occurs with primary union that is typical of an incision opened under ideal conditions; Healing occurs from side to side, dead space has been eliminalted and the wound edges are accurately approximated FIRST INTENTION
A type of needle in which the suture must be threaded by pulling the strand into a V-shaped area jusst above the eye FRENCH EYED NEEDLE
Easily torn or crumbled FRIABLE
Abnormal protrusion of an organ or other body structure through an opening in a covering membrane or muscle HERNIATION
Patient whose immune system has decreased due to disease, or intentionally decreased with immunosuppressive drugs for organ transplant patients to prevent organ rejection IMMUNOSUPPRESSED PATIENT
The body's protective response to injury or tissue destruction INFLAMMATION
Cut or tear LACERATION
The placement of a suture tie around a vessel or other anatomical structure for the purpose of constriction LIGATED
Suture material made of a single thread like structure MONOFILAMENT
Sterile fine mesh guaze that is loosely placed in a chronic wound or one that has been left open to heal by second intention PACKING
Main suture that approximates the wound edges for first intention healing to occur PRIMARY SUTURE LINE
A synthetic coating used on certain types of nylon suture material to reduce the drag through tissue PTFE (POLY-TETRA-FLUORO-ETHYLENE)
Healing that occurs when a wound fails to heal by primary union, or the wound is left open and allowed to heal from the inside to the outside by filling with granulation tissue SECOND INTENTION
Sutures placed to support and ease the tension on the primary suture line, thus reinforcing the wound closure and obliterating any dead space SECONDRY SUTURE LINE
Strand of suture material with an eyeless needle attached by the manufacturer; the needle is continuous with the suture strand SWAGED
Amount of pull or tension that a suture strand will withstand before breaking; expressed in pounds TENSILE STRENGTH
Healing that occurs when two granulated surfaces are approximated; also referred to as delayed primary closure THIRD INTENTION
Thin strips made of silicone that can be placed around a vessel, nerve, or duct for the purposes or retracting or isolating; the loops are colored for easy identification of the retracted structures VESSEL LOOP
CLASS I-CLEAN-INFECTION RATE 1-5% Incision made under ideal surgical conditions; No break in sterile technique during procedure; Primary closure; No wound drain; No entry to aerodigestive or genitourinary tract
CLASS II-CLEAN CONTAMINATED-INFECTION RATE 8-11% Primary closure; Wound drained; Minor break in sterile technique occurred; Controlled entry to aerodigestige (included billary tract) or genitourinary tract
CLASS III-CONTAMINATED-INFECTION RATE 15-20% Open traumatic wound (less than 4 hours old); Major break in sterile technique occurred; Acute inflammation present; Entry to aerodigestive (includes billary tract) or genitourinary tract with spillage
CLASS IV-DIRTY/INFECTED-INFECTION RATE 27-40% Open traumatic wound (more than 4 hours old); Microbial contamination prior to procedure; Perforated viscus
CLOSED WOUND The skin remains intact, but underlying tissue suffer damage
OPEN WOUND The integrity of the skin is destroyed
SIMPLE WOUND The integrity of the skin is destroyed. There is no loss or desstruction of tissue nd there is no foreign body in the wound
COMPLICATED WOUND Tissue is lost or destroyed, or a foreign body remains in the wound.
CLEAN WOUND Wound edges can be approximated and secured. A clean wound is expected to hel by first intention.
