Gypsum Bandage in Medicine
Plaster bandage has a special meaning in medicine. It is widely used nowadays in traumatology and orthopedics.
What is a plaster bandage
So called gauze dressing, prepared with plaster and capable of hardening. Specifically, the medical plaster bandage is a specialized cotton, non-hygroscopic (white or yellow) gauze, which is completely saturated with the plaster mass. According to GOST gauze has a width of 10 to 20 cm and a length of 3 meters. The most commonly used non-pouring plaster bandage. It is very convenient in work and when applying dressings.
The gypsum itself is an odorless fine calcium sulfate. The finished bandage hardens within 24 hours, leaving no signs of softening.
In clinics and hospitals, surgeons and orthopedists always have a plaster bandage. Applying a bandage is possible on almost any part of the body. It is used for fractures, bruises, as well as sprains and damage to the soft tissues of the body. Sometimes it is practiced dressing with diseases associated with the musculoskeletal system.The bone or joint is fixed for a certain period of time in the correct position to correct the defect.
The main advantages that the gypsum bandage has are density and uniform imposition on the body. The bandage is adjacent to the skin, quickly hardens and is very easily removed.
Types of gypsum bandages
There are two types of plaster bandages and dressings, depending on the lining:
- The bandage has a cotton-gauze lining. It has its drawbacks - mainly poor fixation and pressure on the body.
- Bandage without lining. It is applied directly to the skin.
When edema develops, dressing with medical plaster can interfere and be tight. A replacement is then required in order not to deform the injured parts of the body. In another case, when the edema subsides, the gypsum gauze bandage should also be replaced. A weakened dressing will not give the desired effect.
The main disadvantage is that gypsum can cause an allergic reaction on the skin, peeling and irritation.
Preparation of gypsum bandage
For the manufacture of bandages use dry gypsum, resembling the texture of flour or starch - it is crumbly, grain to grain.Such bandages are purchased at a pharmacy or prepared independently. They roll out a length of 50-60 cm and put a thin layer of gypsum. Thus, the length can be up to three meters. Ready gypsum bandage stored in a dry place, protected from direct sunlight.
- Prepare water with a temperature of 10 to 20С.
- Immerse the bandage in it so that the air is completely out of the roll (it will take 1-2 seconds).
- Squeeze moisture from the roll. The required amount of gypsum will remain on the fabric.
Bandage can be applied in various ways. In medical practice, currently used the following types of dressings:
- Circular. Completely cover the limb around the entire circumference and fix it in the desired position.
- Longuets. Superimposed on the back side and easy to remove.
- Longon-circular. Possess properties of the previous two.
Only a specialist should be involved in dressing.
Mode of application
A plaster cast is applied directly to the skin, without shaving the hair. Sometimes an anesthetic injection is given. Be sure to treat and disinfect the site of damage, especially if there are open wounds.
Due to the fixing property, it is used to put tires on, to fix the bone in the desired position with open and closed fractures. 2-3 minutes after preparation, the bandage should be put on the injured surface and wait until it is completely dry. The bandage should fit evenly, without wrinkling or kinking, tightly enveloping the desired surface.
After a certain time (about a month), the bandage is removed using scissors and forceps. It is simply cut. Sometimes a spatula is used to separate and not damage the skin.
After removing the plaster cast, the locomotor function of the damaged part of the body is restored for some time. The patient develops a limb with the help of massage and physical culture, takes calcium to strengthen bones.
