Check the circulation at the end of the toe every hour for 6 hours after the start of the plaster treatment, and then maintain it at 4 times a day. Gently apply pressure to the toe to observe the terminal circulation. Usually, the toe will turn white after pressure and then quickly return to a normal pink color, indicating good terminal circulation. If the toe and nail bed appear black and cold, and do not return from white to pink quickly after pressure, the cast may be too tight. If this occurs, contact your doctor promptly to have the cast checked. If it is a soft cast bandage, it can be removed first and then followed up with the doctor. Pay attention to the position of the toe at the end of the cast. If the toe is retracted into the cast, then the cast may slip out of place. This may cause a pressure sore on the skin and the cast should be replaced immediately by the physician. Keep the cast clean and dry. If the surface of the cast is contaminated, it can be cleaned with a damp cloth. Elevate the affected limb after the cast is fixed, either with a pillow or a soft pad underneath until the cast is completely dry and hard. After going home, the affected limb should be elevated with a pillow when the child is in the supine position, which can prevent pressure sores on the heel. During diaper changes, it is important to prevent urine and stool from entering the cast. When using disposable diapers, do not wrap the upper part of the cast into the diaper.
