Write a note on Iontophoresis. Explain its method of treatment and contraindications?
IONTOPHORESIS: DEFINITION: It is defined as a technique in which medically useful ions are driven through the patient's skin into the tissues. PRINCIPLE: The basic principal is to place the ion under an electrode with the same charge; e.g. a negative ion is applied under the cathode. This electrode is known as active electrode. A constant current is then applied and the ion is electrically propelled into the patient. HYPERHIDROSIS: Constant current is used in the treatment of Hyperhidrosis ( excessive sweating ). The use of tap water for this treatment produces no side effects but the ions in it may not inhibit sweating and therefore the use of anticholinergic compound in water is recommended. Apparatus: The apparatus required is: a source of constant current of low voltage and low amperage; a shallow plastic tray for the anode a foot or arm bath for the cathode two large electrodes and leads; two large lint pads to cover the
