Final answer:
Cast care rules are vital for the proper use and maintenance of plaster, large plaster, and fiberglass casts. They usually include keeping the cast dry, refraining from inserting objects into the cast, and managing itching with cool air. Also, plaster casts need time to set, large plaster casts require additional support due to size, and fiberglass casts offer greater durability and water resistance.
Step-by-step explanation:
The process of applying and caring for a plaster cast, a large plaster cast, and a fiberglass cast involves specific steps and precautions. It’s essential to follow proper cast conversion rules to ensure that the cast is effective in immobilizing the affected area and promoting healing.
General Cast Care Rules
Keep the cast dry to maintain its rigidity and shape.
Avoid inserting objects inside the cast, as this can cause skin irritation or infections.
Use a blow dryer on a cool setting to relieve itching, but never apply heat directly to the cast.
Additional Rules for a Plaster Cast
Wait for the plaster to fully set, which can take up to 48 hours, before bearing weight or walking on it.
Check the cast regularly for cracks or soft spots, which can compromise the stability of the cast.
Rules for a Large Plaster Cast
Due to the weight and size, additional support may be necessary to keep the limb elevated and reduce swelling.
Be extra careful when moving to prevent the cast from breaking.
Rules for a Fiberglass Cast
Fiberglass casts are more durable and lighter than plaster casts, allowing for better mobility.
They are also water-resistant, but it’s still recommended to wrap the cast when showering to prevent soaking the padding.
