powder bed

powder bed

Etymology: L, pulvis, dust; AS, bedd
a treatment in which large areas of a patient's body are kept in contact with a powdered medication for a certain time. It is usually repeated three times a day, as necessary. A bed that has already been made is prepared by placing a full-sized sheet lengthwise over the linen. The powder is spread on the sheet from a shaker. The patient lies supine on the powdered sheet. Areas of skin that are apposed are separated with gauze, and powder is shaken over the patient's body. The powdered sheet is then wrapped around the limbs and the trunk from the side to keep the powder in contact with the body. The patient is virtually helpless during treatment and requires close attention from the nurse.
