(Wound dressing& Irrigation)
Nursing Defined :
''to put the patient in the best condition for nature to act upon him ''
Wound Dressing : The process of applying a protective sterile covering of gauze of the material to a wound and giving necessary care by technique .
Purpose :
1-To protect the wound from mechanical trauma .
2- To prevent infection .
3-To assess the healing process.
4-To promote wound healing by primary intention .
Wound irrigation : The washing or flushing out of a wound.
Purpose :
1-To apply heat and hasten the healing process .
2- To apply an antimicrobial solution .
3-To clean the area.
Sign of wound /
It is uncertain how accurately classic signs of acute infection identify infection in chronic wounds, or if the signs of infection specific to secondary wounds are better indicators of infection in these wounds. The purpose of this study was to examine the validity of the "classic" signs (i.e., pain, erythema, edema, heat, and purulence) and the signs specific to secondary wounds (i.e., serous exudate, delayed healing, discoloration of granulation tissue, friable granulation tissue, pocketing at the base of the wound, foul odor, and wound breakdown). Thirty-six chronic wounds were assessed for these signs and symptoms of infection with interobserver reliability ranging from 0.53 to 1.00. The wounds were then quantitatively cultured, and 11 (31%) were found to be infected. Increasing pain, friable granulation tissue, foul odor, and wound breakdown showed validity based on sensitivity, specificity, discriminatory power, and positive predictive values. The signs specific to secondary wounds were better indicators of chronic wound infection than the classic signs with a mean sensitivity of 0.62 and 0.38, respectively. None of the signs or symptoms was a necessary indicator of infection, but increasing pain and wound breakdown were both sufficient indicators with specificity of 100%.
CAUSES PROBLEMS :
Wound dressings can cause problems, including:
• Maceration (sogginess) of surrounding skin (change dressing frequently and use a more absorbent dressing)
• Irritant contact dermatitis (protect skin with emollient or barrier film)
• Allergic contact dermatitis (uncommon: change dressing type, apply topical steroids)
Dressing (medical)
A dressing is an adjunct used by a person for application to a wound in order to promote healing and/or prevent further harm. A dressing is designed to be in direct contact with the wound, which makes it different to a bandage, which is primarily used to hold a dressing in place. Some organisations classify them as the same thing (for example, the British Pharmacopoeia) and the terms are used interchangeably by some people. Dressings are frequently used in first aid and nursing.

Core purposes of a dressing
A dressing can have a number of purposes, depending on the type, severity and position of the wound, although all purposes are focused towards promoting recovery and preventing further harm from the wound. Key purposes of are dressing are:
Stem bleeding - Helps to seal the wound to expedite the clotting process
Absorb exudate - Soak up blood, plasma and other fluids exuded from the wound, containing it in one place
Ease pain - Some dressings may have a pain relieving effect, and others may have a placebo effect
Debride the wound - The removal of slough and foreign objects from the wound
Protection from infection and mechanical damage, and
Promote healing - through granulation and epithelialisation
Types of dressing
Historically, a dressing was usually a piece of material, sometimes cloth, but the use of cobwebs, dung, leaves and honey have also been described. However, modern dressings [1] include gauzes (which may be impregnated with an agent designed to help sterility or to speed healing), films, gels, foams, hydrocolloids, alginates, hydrogels and polysaccharide pastes, granules and beads. Dressings can be impregnated with antiseptic chemicals, as in boracic lint or where medicinal Castor oil was used in the first surgical dressings [2]
In the 1960s, George Winter published his controversial research on moist healing. Previously, the accepted wisdom was that in order to prevent infection of a wound, the wound should be kept as dry as possible. Winter demonstrated that wounds which were kept moist healed faster than those which were left exposed to the air or covered with traditional dressings.
Ideally, dressings should:
Control the moisture content, so that the wound stays moist;
Protect the wound from infection;
Remove slough;
Maintain the optimum pH and temperature to encourage healing;
Usage of dressings
Applying a dressing is a first aid skill, although many people undertake the practice with no training - especially on minor wounds. Modern dressings will almost all come in a prepackaged sterile wrapping, date coded to ensure sterility, this is due to the fact that it will come in to direct contact with the wound, and sterility is required in order to fulfil the 'Protection from infection' aim of a dressing.
Historically, and still the case in many less developed areas and in an emergency, dressings are often improvised as needed. This can consist of anything, including clothing or spare material, which will fulfil some of the basic tenets of a dressing - usually stemming bleeding and absorbing exudate.
Applying and changing dressings is one common task in nursing.
An "ideal" wound dressing is one that is sterile, breathable, and encourages a moist healing environment. This will then reduce the risk of infection, help the wound heal more quickly, and reduce scarring.
