What hygiene measures should be taught to a patient receiving external radiotherapy?

The recommended hygiene measure for a patient receiving external radiotherapy involves using plain water only without soaps and gently patting the skin dry. This approach is important because the skin in the area being treated can become sensitive and susceptible to irritation due to radiation. Soaps, particularly those with fragrances or harsh chemicals, can further irritate the skin, exacerbating any discomfort or damage caused by the therapy.

By using plain water, the patient minimizes the risk of further irritation while still maintaining cleanliness. The method of patting dry, as opposed to rubbing, helps to avoid additional abrasion on already sensitive skin. This care is crucial for promoting healing and preventing complications during radiotherapy treatment.

In contrast, using favorite body washes, alcohol-based wipes, or rinsing with hot water and scrubbing can all potentially lead to increased skin irritation or damage, which is why these methods are not advisable in this context.
