What Is a Plaster Bandage?

Gypsum bandage is made of sizing gauze bandage and cooked gypsum powder. It can be hardened and shaped in a short time after soaking in water. It has strong shaping ability and good stability. It is used for orthopedic or orthopedic fixation, making of molds, assistive devices for prostheses, and protective braces for burns. ^[1]

Suitable for orthopedic fracture fixation, external fixation of orthopedic surgery, inflammatory limb braking, osteomyelitis, bone tuberculosis, bone tumor surgery and osteoarthroplasty limb fixation. It can also be used to make pallets, prosthetic auxiliary tools and various support tools Manufacturing of mold models such as auxiliary materials. ^[2]

Operation method of plaster bandage

1. Dip: Dip a roll of product into the warm water at an angle of 45 degrees until no continuous air bubbles are generated.

2. Squeeze: Take out the product and squeeze it from both ends of the product to the middle with both hands.

3. Winding: The product is evenly wound around the affected part.

4. Flattening: When bandaging, the banding should be done by hand while bandaging.

Precautions for plaster bandages

1. When the gypsum bandage is impregnated, the water temperature must be 25 -30 , and the impregnation time is about 5-15 seconds.

2. The winding process of the plaster bandage must be completed within its curing time.

3. Store in a room with a relative humidity not exceeding 80%, non-corrosive gas and well-ventilated.

New plaster bandage

The new type of plaster bandage is also called "polymer bandage". It is divided into glass fiber polymer bandage and polyester fiber polymer bandage. They are made of glass fiber or polyester fiber coated with polyurethane compound. The latter is the most commonly used and consists of multiple layers. It is made of polymer fibers impregnated with polyurethane and polyester, and has good biocompatibility. It has the characteristics of fast hardening, high strength, and is not afraid of water. It is an upgraded product of traditional plaster bandages ^[3] , as shown in Figure 1.

In order for orthopedic surgeons to keep the fractured limb fixed after the limb is reset, the patient needs to be cast with plaster. Due to the inconvenience of using plaster bandages, more and more doctors have begun to use medical polymer bandages and medical polymer splints. Replace plaster bandages and casts. The clinical features are as follows:

Patient's feelings	Experience of medical staff	other
Bath and medicated bath available	Easy to operate and hygienic	X-ray completely
Lightweight, comfortable and beautiful	Easy to shape	Normal temperature water can activate hardening
Safe, breathable and cool	Easy to observe fracture healing	Withstands weight within 20 minutes
Can wear clothes	Wounds are easy to leave	Non-toxic and no chemical reaction

Instructions:

1. Select the appropriate type of bandage according to the location to be fixed.

2. Use a tissue or cotton cover as a pad for the parts to be fixed.

3. Put on latex gloves.

4. Open the package (open one bag at a time, do not open more than one at a time to avoid failure. Take out the bandage and soak it in normal temperature water for 3-4 seconds, squeeze it 2-3 times, and remove the excess water.

5. Spiral winding at the fixed part overlaps 1 / 2-2 / 3 each turn, with moderate elasticity, 5-6 layers for load-bearing parts, and 3-4 layers for auxiliary parts.

6. Shape the gloves with wet water to make them tightly combined and smooth the surface. This should be completed within 2-3 minutes. Use an electric plaster saw for removal.

Compared with traditional plaster bandages, polymer plaster bandages have many advantages as follows:

1. Comfort and safety: After the bandage is dry, the shrinkage is small, and the skin will not feel tight and itchy after the plaster bandage is dry. There will also not be any discomfort in the patient's skin due to thermogenic reactions during the hardening process of gypsum and water absorption and recrystallization.

2. Good breathability: The bandage uses high-quality raw yarn with good breathability, which solves the discomfort of hot skin and itching caused by long-term local tube bandage and poor breathability, which is beneficial to skin metabolism.

3. Light weight and high hardness: The impact strength of the bandage after curing is 20 times that of the traditional plaster bandage. This feature plays a reliable role in maintaining the correct reset. There are few fixing materials and light weight. The polymer bandage is only 1/5 of the weight of the plaster and 1/3 of the thickness. It can reduce the load on the affected area, which is beneficial to local blood circulation, promotes healing, and minimizes the burden of human activities without causing inconvenience.

4. Excellent projection: The splint and bandage have good permeability to radiation, and the X-ray effect is clear, which can ensure that the doctor can accurately grasp the bone connection and bone healing of the affected area. It is not necessary to remove the bandage during radiography to facilitate Accurately performing surgery is conducive to reduction and understanding of healing.

5. Good water resistance: The bandage has good water resistance, which can block the infiltration of 85% of the moisture from outside. After the affected area is exposed to water, it can effectively ensure that the affected area is dry, easy to clean and care.

6. Convenient operation, flexibility and good plasticity: when there is skin trauma on the fixed part or long operation time, it can be fixed directly without wet water. After fixing, you can spray water on the outer layer of the package to accelerate the hardening speed. Good plasticity, high bending and tensile strength, can be bent freely, bandages can be made into tube, bracket and plywood. Easy to operate, just need room temperature water, without any heating equipment, can be fixed in a short time. Good shape and moderate elasticity.

7. Wide range of applications: orthopedic fixation, orthopedic orthopedics, prosthetic auxiliary functions, support tools, local protective braces for burns, etc.

8. Fast curing, hardening begins in 2-3 minutes, hardening begins, hardening begins in 3-5 minutes, and can bear weight after 20 minutes. By adjusting the water temperature, the hardening time can be adjusted, the water temperature is increased, the hardening time is short, the water temperature is reduced, and the hardening time is long. When the bandage is immersed in water, the plaster is rarely lost. The drying time is fast and completely dry in 36 hours. Strong adaptability, high temperature resistance (+ 40 ) and high cold (-40 ), non-toxic, non-irritating, non-allergic.

9. Environmental protection. After setting, it is resistant to moisture and humidity, non-toxic, non-irritating and odorous. It is easily removed after healing. It is cut with a special plaster saw to remove it. The special plaster saw is hard to eat and not soft, and will not hurt the skin. Complete combustion treatment is thorough and protect the environment. ^[3]
