Nurses can use drinkable tap water as a safe alternative to normal saline to clean wounds, according to the findings of a Cochrane Review.
Researchers studied 11 clinical trials. They found that cleaning wounds with tap water or clean water that had been boiled was as effective at controlling infections as using saline.
But lead author Ritin Fernandez, from the Centre for Applied Nursing Research in New South Wales, Australia, stressed that a decision to use tap water should take into account the quality of water, the nature of the wound and the patient’s general condition.
