First, the patient should be placed in a cool, dry and ventilated ward and environment, and the doors and windows should not be closed tightly. Secondly, when fever is present, the patient should be placed in a flat position as far as possible. At this time, the patient’s clothes that are too tight or too hot should be removed and replaced with some cotton clothes that are conducive to the absorption of sweat, so that eczema does not appear on the body. Third, we should also pay attention to turning and patting the back to avoid bed sores and other conditions. Fourth, the patient should also often be given physical cooling, to pay attention to the patient’s temperature monitoring.
