Sutures
Dressings
Catheters-Tubes-Drains
Wound Healing
Hemostasis
100
A strand of suture made of more than one thread held together by twisting or braiding
What is a multifilament suture
100
Lies against the wound to provide a barrier against pathogens Allows passageway for wound’s secretions
What is inner layer of dressing
100
These have port for inflation of balloon, port for instilling irrigation fluid, port for drainage of urine or irrigation
What is 3-way Foley Catheter
100
Situations surrounding injury were clean Wound is cared for within 6 hours Will heal by first intention
What is a clean wound
100
Slow but continuous blood loss from capillaries and small vessels, can become significant if not controlled
What is venous bleeding
200
A suture strand attached to a clamp (right angle or tonsil clamp)
What is a tie on a pass
200
These are gauze sponges and strips used to fill a cavity or wound Usually removed in PACU or the next day by the surgeon
What is packing
200
These are used to drain abscessed body cavity, no collection device is used-drains unto dressing, can be secured with stitch or safety pin
What is a Penrose drain
200
This process occurs with injury or incision- vessels contract or constrict. This is termed:
What is vasoconstriction
300
Allowing tissue fluids to move along the strand If infection is present it can be drawn into the wound through the suture strand which acts as a wick
What is capilarity
300
Used when frequent wound inspections or dressing changes are needed- provides easy access to wound Used when frequent wound inspections or dressing changes are needed- provides easy access to wound Absorbs moderate-large amount of drainage Often used in GU (urology) surgery
What is Montgomery Strap Dressing
300
A double lumen tube for gastric decompression that is usually inserted by anesthesia and may be connected to intermittent or constant suction
What is a Salem Sump tube
300
Starts with injury Lasts 1-6 days Exudate and fibrin loosely binds edges together
What is Lag-inflammatory-substrate phase of wound healing
300
Blood donated by a person for their own use or blood from the patient that is recovered and reinfused
What is autotransfusion
400
Prepared from collagen of healthy mammals or from a synthetic polymer Capable of being absorbed by tissue but may be treated to resist absorption
What is absorbable suture
400
Provides a form-fitting mold that may be criss-crossed over a small dressing and tied Used when can’t apply pressure dressing-such as on face or neck
What is a stent dressing
400
These are used after extensive dissection or where moderate to large amounts of drainage are expected. Has self-contained collection device and manual suction- creates a negative pressure suction
What is a Hemovac
400
14-21 days after injury or incision Scar (cicatrix) forms- pales Slow sustained increased tensile strength
What is Maturation/Remodeling Phase of wound healing
400
When cells are injured - these clump to ends of vessels and release thromboplastin and other substances (adenosine diphosphate-ADP, epinephrine, serotonin)
What are platelets
500
Don't soak, can dip in saline before use Don’t jerk or stretch it= weakens it Don’t straighten by running fingers down strand DO grasp ends and tug gently to straighten DO cut ¼” from knot
What is how to handle catgut suture.
500
Used after extensive operations especially in plastic surgery and knee and breast surgery It eliminates dead space= prevents edema or hematoma
What is a pressure dressing
500
Are smaller in diameter and longer in length than uretheral – 3,5,7 Fr Are usually inserted into ureter by urologist during cystoscopy Are used to obtain specimen directly from renal pelvis Are used to identify (mark) ureter during pelvic procedures to prevent accidental injury
What is a ureteral catheter
500
Rapid healing phase 6-14 days Fibroblasts bridge wound edges and secrete collagen Collagen fibers form = increased tensile strength
What is Proliferative/Healing Phase of wound healing.
500
These substances are released by the liver and form a fibrin clot that withstand arterial bleeding
What are prothrombin and fibrinogen
