During perineal washing, place an absorbent sheet beneath the area being washed to stop water spreading onto the bed. This article explains how to position disposable sheets, precautions for use, and product sizes.

What is an absorbent sheet?

Water from the washing spray can splash and wet the bed during perineal washing. A wide absorbent sheet covers the splash area. Using one during care involving diarrhea can make diaper changes more reassuring.

Absorbent sheets range from small to wide sizes. Check the width and length needed to cover the area where washing water spreads, as well as the required absorbency. Compare individual product dimensions to determine whether a sheet is wider than a flat diaper sheet.

How to use an absorbent sheet

First, position the person appropriately in bed

Roll the person onto their side. Fold the sheet as needed and tuck the folded side beneath the area from the back to the buttocks.

Roll the person onto the opposite side. Fully unfold the sheet and make both sides even.

Make a final check for wrinkles to finish.

Absorbent sheet precautions

Absorbent sheets are sometimes used as disposable waterproof bed protection rather than for perineal washing. In that situation, wrinkles can press on the skin and contribute to skin problems. Because the sheets are non-breathable, heat and moisture can also build up in the bedding. Take care, as a hot, humid environment can contribute to skin problems.
