injured blood vessels constrict and platelets gather to stop bleeding. Clots form a fibrin matrix that later proves a framework for cellular repair. -Proliferative Phase- appearance of new blood vessels begins and lasts from 3-24 days. Main activities are filling of wound with granulation tissue, contraction of the wound, resurfacing of wound by epithelialization. - Remodeling- final stage of healing, sometimes takes pace for more than a year. Collagen scar continues or reorganize and gain strength. Usually scar tissue contains fewer pigmented cells (melanocytes) and has a lighter color. Hyperbaric therapy (HBOT) : drastically increases partial pressure of O2 in tissues; increased transport capacity of O2 in blood (by plasma); more O2 to cells = increased healing; other treatments include treatment of decompression sickness (diving “bends”) and air embolism Types of Wound Drains/drainage evacuators: Hemovac (Negative pressure)- used primarily to improve the speed of recovery in burn victims and to enhance healing in chronic or severe wounds; wound is sealed using gauze or a dressing of foam, covered with a drape layer, and then a vacuum source which adds negative pressure to the wound area. The vacuum helps the drainage of wound areas by removing fluid and dessicated tissue, enhancing blood flow through the affected region, lowering bacterial levels, stimulating cell growth, closing the wound edges, and promoting granulation tissue. The dressing will be replaced frequently to remove wound fluids. This technique is most commonly associated with chronic wounds but is also used in cases of diabetic foot ulcers, traumatic wounds, and venous insufficiency ulcers. Jackson-Pratt- ( Bulb drain), a continuous suction pressure is applied to the wound by use of a flexible bulb. The bulb is used both as a mechanism of providing suction and as a reservoir for the escaping fluid. After the device has been attached to the wound, a patient needs only to squeeze the plastic bulb to create suction. Once the bulb has filled with discharge from the wound, it can easily be removed, washed, and reattached to drain more liquid. Physicians generally recommend that the bulb should be removed when it has become over half full with liquid. When cleaning the system, a damp towel or cloth should be used to strip the tube of any clots or other obstructions that may limit the flow of the removal liquid. Penrose- length of soft rubber tubing that is placed inside of a wound area to facilitate the drainage of wound areas. The tubing can also be fabricated from silicon. Usually, it is attached to the wound directly after surgery to avoid the proliferation of bacteria in pools of blood or other bodily fluids. In addition, hydrocephalus patients have found this drainage format beneficial in draining cerebrospinal fluid. TLS -
