Plaster of Pairs Bandages

Plaster of Pairs Bandages

If you've ever broken a bone, you know how much of a pain it can be to wear a cast or even to move your arm around. The plaster bandages are made by putting plaster of Paris on gauze and then wrapping that with tape and gauze. And the good thing is, they're not just for broken bones - these bandages are also used for scrapes and cuts too!

How Plaster of Pairs are made

Plaster of Paris is a white powder that is derived from calcium sulfate. The powder is mixed with water to create a paste, which can be used to mould or cast objects. When the paste dries, it hardens to form a strong and durable material. The process of making plaster of Paris is relatively simple. First, the calcium sulfate is calcined, or heated, to drive off any water molecules that may be present. This leaves behind anhydrous calcium sulfate, which is then ground into a fine powder. Next, the powder is combined with water to form a slurry, or wet mixture. The ratio of powder to water will determine the final properties of the plaster of Paris; a higher ratio of powder will result in a harder material, while a lower ratio will result in a softer material. Once the desired consistency is achieved, the slurry is poured into moulds or casts and left to dry. As the water evaporates, the plaster of Paris begins to harden. The final product can be sanded, painted, or otherwise finished as desired.

How to properly apply a plaster of paris bandage

When applying a plaster of paris bandage, it is important to take the following steps: 1. Choose the right size bandage for the area you are treating. 2. Clean the skin around the wound with soap and water. 3. Apply a layer of petroleum jelly or other lubricant to the skin. This will help prevent the plaster from sticking to the skin. 4. Wrap the bandage around the affected area, being sure to smooth out any wrinkles or creases. Start at the bottom of the limb and work your way up. 5. Once you reach the top of the limb, secure the bandage in place with tape or another adhesive material. 6. Check regularly to make sure that the bandage is still in place and that there are no new wrinkles or creases forming. If necessary, reapply petroleum jelly or other lubricant to prevent sticking.

How to remove a plaster of paris bandage

Plaster of paris is a material that is used to make casts for broken bones. It is also used as a bandage to support injured muscles and joints. Plaster of paris bandages are easy to apply and remove. However, if they are not removed correctly, they can cause skin irritations. To remove a plaster of paris bandage, first wet the bandage with warm water. This will help to loosen the adhesive that is holding the bandage in place. Next, slowly peel the bandage away from the skin. If the bandage is stuck, you can use a pair of tweezers to gently pull it off. Once the bandage is removed, wash the area with soap and water.

Alternatives

There are a few alternatives to using plaster of pairs, depending on what you're trying to achieve. If you need a strong bond for something that will be under a lot of stress, like repairing a broken bone, then you'll want to use a stronger material like fiberglass. For smaller projects or repairs, super glue or epoxy might work just as well.

Plaster of Pairs Bandages, Various materials have been used since ancient times to help immobilize fractures. In this review, we discuss the history and developments of these materials as well as plaster of Paris. There has been a recent trend away from non-operative management of fractures, and skills in the use of plaster of Paris are declining. For the successful treatment of patients, it is important to appreciate how plaster works, how it should be used, and what can go wrong. In this review, we also discuss principles of applications and complications of plaster of Paris.

HISTORY OF INJURED LIMB IMMOBILIZATION

Immobilization of injured limbs has been performed for thousands of years. Before contemporary casting materials became widely used, people used a variety of materials to form rigid casts. Over the centuries immobilization has evolved from using simple wooden splints and rags to plaster of pairs bandages, fiber, and soft casts.

The earliest examples of the active management of fractures in humans were discovered at Naga-ed-Der in 1903 during the Hearst Egyptian Expedition of the University of California led by Dr. GA Reisner. In a paper published in the British Medical Journal in 1908, Mr. G. Elliot-Smith describes two sets of splints that were found during excavations of tombs from the fifth dynasty (2494-2345 BC). One of the earliest descriptions of casting material was by Hippocrates in 350 BC. He wrote about wrapping injured limbs in bandages soaked in wax and resin. According to the earliest known surgical text The Edwin Smith Papyrus (copied circa 1600 BC), the Egyptians were using self-setting bandages, probably derived from those used by the embalmers. Later descriptions of casting came from the Arab physician Rhazes Athuriscus. El Zahrawi (960-1013 AD), a surgeon born near Córdoba in Spain, described the use of both clay gum mixtures and flour and egg white as casting materials. Starch-based casts appear to have been the standard treatment with only minor changes until the beginning of the 19th century with only a few minor changes.

Further advances in the choice of materials were made during the wars. In the 18th century, Henri François Le Dran, who practiced surgery at Hôpital de la Charité in Paris and was a surgeon in Germany Army and consulting surgeon to the camps and armies of King Louis XV, used to soak his bandages with egg white, vinegar, and clay powder or plaster. A modification to the materials used was introduced by the father of modern military surgery, Baron Dominique Jean Larrey, a French surgeon in Napoleon’s army. He was a surgeon in chief from 1797 till the Battle of Waterloo in 1815. Larry's modification was adopted from Don Eugenio de la Penna who bandaged the fracture with linen that had first been moistened with Camphor spirit, egg whites, and lead-acetate. Unfortunately, these were not used on a large scale due to costs. Baron Louis Joseph G Seutin (1793-1862) was a belgian professor and surgeon in chief at the Universite Libre de Bruxelles. As a chief doctor of the Belgian Army, he fought in at Waterloo. He became famous for inventing starch bandages known as “La Bandage Immobile” or “L’Appareil Amidonnee” that consisted of strips of linen or bandages and carton splints, soaked in starch and wrapped around the limb.

Seutin’s method was popular in England by Joseph Samson Gamgee, the Birmingham surgeon who amongst other things invented Gamgee tissue. In the first half of the 19th century, it was not popular to reduce fractures until the swelling of the soft tissue decreased. Following Seutin’s rules, Gamgee insisted on immediate reduction and application of the starched apparatus and registered spectacular success.

ORIGINS OF Plaster of Pairs Bandages

Plaster of Pairs Bandages is produced by removing the impurities from the mined gypsum and then heating it under controlled conditions to reduce the amount of water of crystallization. Plaster of Paris was well known as a building material for many centuries before it was introduced as casting material. Egyptians, as well as Romans, used it for plastering walls however not more is known on plaster use after the end of Roman occupation. In modern-day England, it was widely excavated in Roman coffins discovered in York, and on the walls in the military barracks of the Second Augustan Legion excavated at Caerleon in Monmouthshire. In medieval times gypsum was used only for alabaster statuary. There are various accounts describing the origin of the name plaster of Paris. One account mentions King Henry III who visited Paris in 1254 and was so impressed by fine white walls that he introduced similar plastering in England where it became known as plaster of Paris.

The first use of plaster of pairs bandages as a cast for injured limbs took place through a technique known as plâtre coulé that became popular in Europe at the beginning of the century. This technique involved pouring plaster of Paris around injured limbs encased in a wooden construct. Due to the weight of the construct, the patient was largely confined to bed during the period of fracture healing. This disadvantage was highlighted by Seutin, but this remained a relatively popular technique in Europe with some surgeons using it for lower limbs only and some using it for both upper and lower. Starched and illuminated bandages were also used as a casting method.

In 1839, Lafargue of St. Emilion used fresh warm starch paste mixed with plaster of Paris powder applied to layers of linen strips. That dressing had the advantage of hardening much quicker, reducing the setting time down to six hours. The Dutch military surgeon Anthonius Mathijsen while working at the military hospital in Haarlem discovered that bandages soaked in water and plaster of Paris were becoming hard within minutes providing sufficient casting for injured limbs. He published his monograph in 1852 in a medical magazine called Repertorium. His plaster bandage was based on the principles of Seutin, who 10 years earlier introduced starched bandages known as bandage amidonnee In his paper entitled “New Method for Application of Plaster-of-Paris Bandage”, Mathijsen highlighted many disadvantages of Seutin’s dressings including lack of self-adjustment to the changing conditions of the limb, long duration of days needed for the casing to become sufficiently solid, carton splints shrinking and becoming shorter when they dried off adversely affecting fractures, and in cases of suppuration or with small children urinating, dressing becoming soft and loosen. Mathijsen’s bandages consisted of strips of coarse cotton cloth with finely powdered plaster rubbed in. This method of preparation was used until 1950.

Nikolay Ivanovich Pirogov, ahead of the department of surgery at the St Petersburg Medico-Surgical Academy and a Russian army surgeon during the Crimean War, conceived his idea to use plaster splints around 1852 while observing the work of a sculptor who used strips of linen soaked in liquid plaster to make models. Pirogov used coarse cloth, either in large pieces or in strips that were immersed in a liquid mixture of plaster of Paris immediately before applying them to limbs protected by stockings and cotton pads. Based on his Crimean experience, Pirogov believed that all patients with fractures due to missile wounds should not be evacuated from the forward dressing stations until the limb had been immobilized in a proper dressing of plaster of Paris. After the war, he refined his method by cutting coarse sailcloth to a defined pattern shaped to fit a part of the body and soaking it in plaster before application
