What bandaging material is most commonly used for a dry dressing? Gauze
When is a nonadherent dressing indicated? When a wound has a raw surface or is expected to have active drainage
Why are frequent dressing changes not optimal? May increase the risk of infection
Under what conditions and for how long should post-op dressings be placed? Placed under sterile conditions and remain in place for 2-5 days, depending on wound size
What are the indications for Montgomery straps? Used when repeated dressing changes are required, such as an abdominal wound that has re-opened
How should adhesive tape (steri-strips) be applied and removed? Applied perpendicular to wound edges and removed by pulling toward the wound
What are the indications for the use of Collodion spray? Small lacerations, such as the scalp
What are the indications for use of reversed spiral bandaging Tubular structures of changing diameter such as the calf or forearm
How long should wet comporesses be used? No more than 24 hours, may result in skin maceration
Which "support" material is the most versatile? Plaster-of-Paris, can be molded into many shapes
When is posterior splinting most useful? For quick and initial mobilization of acute injuries, such as nondisplaced fractures and severe ankle sprains.
Which type of drain is attached to suction and used to decrease fluids from large wounds? Sump drains - attached to SUCTION
What type of environment is optimal for wound healing? 1. Free from dead tissue 2. Free and protected from infection 3. Moist at the wound surface (but not wet)
What are the signs of an infected wound? 1. Increased pain 2. Erythema around wound 3. Discoloration of wound bed tissue
In comparing plaster vs. synthetic casting material, which is: 1. cheaper 2. stronger 3. more water resistant 4. quicker to dry 1. plaster 2. synthetic 3. synthetic 4. plaster
what is an important advantage of using a splint in a fresh fracture? Allows for significant swelling and immobilization prior to application of a cast
What are the indications for the following splints: 1. thumb spica 2. ulnar gutter 3. radial gutter 4. upper extremity posterior splints 5. lower extremity posterior splints 1. thumb sprain, scaphoid fracture, immobilization following laceration repair. 2. 4th and 5th metacarpal fractures 4. bicep tendonitis, radial head fracture, stable distal humerus fracture 5. stable ankle fractures
What are the indications for the use of cast braces? Used to hold a fractured bone immobile while allowing for joint motion above and below the fracture site, allowing for early ambulation and rehabilitation
Name the different lays that are applied to create a cast 1. Stockinette 2. Webril (soft cotton roll) - tow to three layers, more over bony prominences 3. Plaster or fiberglalss bandages
Name the pre and post splint checks FACTS = Function, arterial pulse, capillary refill, temperature of skin, Sensation
What are common complications associated with casting? 1-3 1. Foreign body causing ulceration or infection; 2. plaster burn; 3. pressure sores - require immediate "window" formation and inspection
What are common complications associated with casting? 4-7 4. Nerve palsy/vessel compromise - requires immediate bi-valve of the cast through all material 5. Diffuse osteoporosis 6. Joint stiffness 7. Dermatitis or loose-cast syndrome
