The use of alginate dressing in orthopaedic dressing change

Based on the theory of wet healing, alginate dressing can control water evaporation, allow oxygen and water vapor to pass through, and isolate external bacteria, reduce the occurrence of wound infection, and create a moist environment between the dressing and the wound. In addition, the alginate dressing has no adhesion to the wound surface, so the granulation tissue will not be damaged when the dressing is removed, and there is no pain, so that the wound surface can heal naturally without going through the general scabbing process. Ordinary cotton gauze dressing adopts the theory of dry healing. The dressing needs to be changed if the wound is slightly exuded. To keep the wound dry, the dressing needs to be changed frequently. Ordinary cotton gauze is easy to adhere to the wound, scab, and peel off the gauze during dressing change. It is easy to damage and destroy the wound surface and new granulation tissue, resulting in slow wound healing and increased pain and discomfort for patients.

Postoperative incisions in orthopedic patients are mostly located on exposed parts of the body, limbs and joints. Alginate dressings have good adhesion and elasticity to the limbs. During functional exercise, with the movement of the limbs, the dressings can follow the skin folds. Deformation, not easy to shift, provides convenience for the early functional exercise of orthopedic patients. Ordinary cotton gauze needs to be fixed with a bandage. When the patient is exercising the limb function, the gauze is very easy to shift, loosen, and fall off, contaminating the sterile wound and increasing the chance of wound infection.

1.3 There are many patients with paraplegia and limited mobility in the department of orthopedics. The patient cannot fully expose the wound to the range that the dressing nurse can easily operate due to the pain. The replacement operation of the salt dressing is quite simple. It only needs to be pasted lightly, especially the wounds on the limbs. A dressing nurse routinely disinfects the wounds, and the alginate dressing can be gently pasted to complete a dressing change, which greatly shortens the time. time required for dressing changes. The alginate dressing has good sealing performance, which isolates the wound from external bacteria, reduces the number of dressing changes, and greatly reduces the labor intensity of nursing staff.

The alginate dressing has a complete range of specifications, which can meet the needs of orthopedic patients with different sizes of postoperative wounds. The appropriate dressing can be selected according to the size of the wound, and can be individually packaged and used immediately after opening, saving operation time and reducing nursing care. cost and time, and improve the efficiency of nursing work. With ordinary gauze dressings, the incision is slow to heal and requires multiple dressing changes, which not only increases the risk of contamination, but also increases the operation time.

The alginate dressing can completely cover the wound. The moist and slightly acidic environment is conducive to the function of neutrophils, enhancing the local sterilization ability, reducing the incidence of infection, and forming a whole with the skin, effectively protecting the nerve endings and avoiding external stimulation. , reduce wound pain, can reduce the discomfort of long-term bedridden patients in orthopaedics.

Orthopedic surgery wound care has attracted the attention of medical staff, especially if the wound after spinal surgery and joint surgery is infected, it means that the operation fails, which not only increases the economic burden on the patient, but also increases the workload for the medical staff, and also affects the The turnover of beds makes patients prone to anxiety and fear, as well as medical disputes. We compare the application of alginate dressing and ordinary gauze in wound care clinically. Sukang alginate dressing can keep the wound warm and moisturizing, create a hypoxic environment and provide the best moist healing environment, which is more conducive to wound healing. . There is no damage when changing the dressing, which can reduce the pain of the patient. The moist environment greatly shortens the healing time of the wound, and also improves the quality of life of the patient, and the treatment cost of the patient is relatively reduced.

Compared with alginate dressings, ordinary gauze dressings have the following deficiencies in clinical application:

①Gauze dressings are generally made of cotton, soft linen and linen. Such dressings have no obvious effect on wound healing, cannot keep the wound moist, and delay wound healing.

② Ordinary gauze dressing is thicker, and it is easy to shift with the turning movement in the tail energy part and the greater trochanter of the femur. This problem is more prominent in emaciated patients.

③ The fibers of the gauze dressing are easy to fall off, causing foreign body reaction and affecting healing. The granulation tissue on the wound surface is easy to grow into the mesh of the dressing, and mechanical damage is easy to occur when the dressing is changed, which can cause pain.

④ Orthopedic surgery patients have many wounds on the limbs, and bandages need to be fixed when changing dressings with ordinary gauze dressings, which can affect the patients’ early functional exercise and are prone to complications such as joint stiffness.

⑤ When using ordinary gauze dressings to change dressings, it needs to be fixed with tape. Some patients are prone to skin allergies to tapes, resulting in blisters, causing new skin problems and wound infections. The dressing needs to be changed several times, and the workload of dressing changes increases.
