title: Iatrogenic burns: beware of microwaves!
abstract: (1) The traditional hot-water bottle now faces competition from a variety of similar devices, such as microwave-heated compresses and gel packs; (2) These devices can cause severe burns; (3) Microwave-heated gel packs can be harmful for two main reasons. First, microwave ovens heat deeply and unevenly and dangerous temperatures can quickly be reached. In addition, gels retain heat longer than other materials such as cotton compresses or towels; (4) Burns are sometimes caused by lengthy contact with an object that is not hot enough to cause pain or even discomfort. The heat perceived by the user does not reflect the quantity of heat actually transferred. Instructions that can be inadequate and that vary among different brands are further contributing factors; (5) These heating devices must be used with care. The recommended microwaving duration must not be exceeded, the device should be let stand for at least 10 minutes before use, and the heat-retaining material should be homogenised before applying the device to the skin.
