Heat Rash Or Prickly Heat
Heat rash is caused by a blockage of the sweat duct by a keratin plug. This condition is caused by excess sweating and inadequate evaporation of the sweat. If this occurs at the surface of the skin, small vesicles (blister-like sacs containing fluid) which are not inflamed, occur on the skin surface (miliaria crystallina). These blisters last only a few hours and burst spontaneously.
This form of miliaria does not itch. If the obstruction is deeper the sweat duct ruptures, producing inflamed papules (miliaria rubra) which is the more severe form of heat rash. The condition is characterised by an intense prickling sensation. This is aggravated by anything that stimulates sweat production.
The patient should be placed in a cool atmosphere and advised to reduce activity to a minimum. The main aim of topical treatment is to relieve the symptoms in order to make the patient comfortable. Soap should be avoided as it may further irritate the skin. Secondary bacterial infection is common.
Advice for the Patient
Avoid sweating: The patient should be advised to avoid situations which may lead to further sweating. Washing the Skin: As soap aggravates the condition, the affected area should be washed with diluted Pinetarsol Solution or Pinetarsol Bath Oil.
Do not use soap. Clothing: This should be light, airy and non-restrictive, preferably of cotton or silk. It should be rinsed well after washing to remove all traces of soap.
