After trauma, people often refer to the process of applying a plaster as "casting." A plaster bandage can be used to wrap a shallow groove-shaped tray to support the limbs or trunk, which is called a plaster tray. It is customary to call the front and rear plaster trays that fix the upper body a plaster bed; or a plaster band can be used to wrap the trunk or limbs into a tube shape. , called gypsum cast. 1. Some issues that should be paid attention to when applying plaster bandages: (1) Before applying plaster, all materials should be prepared to avoid temporary searching, which will affect the progress of the work and further affect the quality of the plaster completion. It is required to prepare sufficient quantities of gypsum rolls, tapes and gypsum powder. The water tank must be large enough and have enough water volume. All kinds of liners and other necessary items such as support sticks must be thought of and prepared in advance. (2) Personnel involved in work must wear aprons and rubber shoes. During operation, there are usually two people, one to operate and one to assist. When placing a large cast, one person must be added to support the patient's position. (3) Prepare the patient: Position the patient, pay attention to the patient's comfort and warmth, cover the patient appropriately with a plastic sheet, and avoid splashing the plaster paste on the patient's face, body, hair and other places that are not necessarily contaminated with plaster. (4) When immersing the gypsum roll in the water, the gypsum roll should be placed flat and not upright to prevent the gypsum powder from spilling from the center of the roll. The gypsum roll must be completely immersed in the water, and wait until the gypsum roll is in the water. When the water stops bubbling, it means the water has been soaked, then take it out of the water. The larger the soaking container is, the more water will soak it in faster. If the water is hot, the plaster will set and dry quickly; if the water is cool, it will dry more slowly. When taking out the gypsum roll from the water, hold both ends of the roll with both hands. After taking out the water, put your hands into it lightly to squeeze out excess water. After taking out one soaked plaster roll from the brief each time, if you need to continue bandaging, put in another dry one. Do not soak several rolls in water at the same time. Because if the plaster roll is not taken out and used immediately after it penetrates into the water, it will become hardened over time. (5) Be careful not to drip water onto the dry plaster bandage. The part of the plaster bandage that is wetted by water will condense into small hard lumps. If these small hard lumps are wrapped in plaster, they can form a pressure point, causing skin necrosis and ulcers. Therefore, plaster bandages that are soaked by water and have hard lumps cannot be reused. You should also not use wet hands to remove plaster bandages from the container in which they are stored. The soaking requirements for gypsum tape are basically the same as those for gypsum rolls, except that when soaking, the gypsum tape must be folded first to make it into a tube shape, and then the two ends of the tape roll should be held loosely with both hands and placed in the water (without leaving the hands on the tape roll). Take it out until the bubbles are gone. If the plaster tape is left open in the water, it is easy to spill the plaster powder. 2. Operation technique: (1) Before operation, you should fully understand the patient's condition, understand the parts to be fixed and the purpose, so as to get the posture correct. In the future, during the bandaging work, do not change the bandaged posture at any time to avoid affecting the effect. The quality of plaster dressing and the effect of fixation. (2) When wrapping a plaster roll, push the roll forward against the body and stroke the bandage with your hands while pushing, so that the layers of the plaster bandage fit tightly, without gaps, and are smooth and wrinkle-free. In this way, after the plaster dries, it will be a multi-layered plaster bandage combined into one solid layer of plaster. Otherwise, the layers of bandages will not fit each other, and the plaster will be soft and not strong. When wrapping a plaster roll, it is important to push the roll against the body. The reason is: if the plaster roll is like a gauze bandage, first unwrap a section and then wrap it, then this section of the unzipped plaster bandage will be Falling downward due to wet weight, wiping. If you want to lift and flatten this section of bandage, you will have to pull hard, so the bandage will not be spread evenly, and it is likely to be pulled too tight and put too much pressure on it. Also, where the trunk and limbs have obvious curves and uneven thickness, do not forcefully pull the plaster bandage to make it flat. Instead, use the method of pulling back and folding to make the bandage fit the body surface. (3) The operation should be steady, accurate, agile, fast and not messy, and do not splash the plaster paste randomly. Bandaging should be done in a planned and step-by-step manner. Assistants should work closely together. During the bandaging process, the patient's position should remain stable, because moving the joint before the plaster is firmly fixed may cause the plaster to break and lose its fixation effect. (4) Do not store too much gypsum paste in the soaking tube. The gypsum mud that has simply settled at the bottom should be cleaned out of the water at any time to make enough water to facilitate soaking. Do not pour gypsum paste into the sewer to prevent it from clogging the water pipes. It should be thrown into the garbage bin.
