Iontophoresis-Bon #174409
| Question | Answer |
|---|---|
| Indications for Iontophoresis (15) | Infection Rhinitis slow healing wounds post traumatic edema plantar warts trigger points peripheral circulatory deficits Gout myositis ossification inflammation local anesthesia hyperhidrosis ischemic ulcers mm pain fungus |
| Contraindications for Iontophoresis (11) | Pregnancy Alergy to Med or DC Metal Implant,sutures,etc. Pacemaker US prior to Ionto Transtemporal region Broken Skin Recent Scars E-Stim otherwise contraindicated Active Bleeding Decreased Sensation |
| Force acting to move ions using iontophoresis depend on... | 1. Strength of elcetrical field2. Impedance of tissue of body to current |
| Hyaluronidase | (+) for subacute and chronic edema |
| Ciltrate | (-) for rheumatoid arthritis (prevents autoimmune response |
| Lithium | (+) for Gout |
| Acetate | (-) for myositis ossification |
| Disadvantages of Iontophoresis | 1. Unreliable results with certain meds2. Need physician's prescription |
| Procedure for Iontophoresis | 1)Skin check,sharp/dull test 2)Clean Skin 3)Turn current down/check wires 4)/Turn on,start on S1 (chg only if MD says) 5)Turn to run,set current to pt tolerance 6)Document:prescription mA/min=1.6 m/A x 26 min. dex |
| Dexamethasone | (-) for inflammation |
| Acetic Acid | (-) for Calcific tendonitis & myositis ossification |
| Iodine | (-) for adhesive capsulitis and other soft tissue adhesions |
| Lidocaine | (+) for soft tissue pain and inflammation |
| Salicylates | (-) for mm and jt pain |
| Calcium Chloride | (+) for Skeletal mm spasms |
| Magnesium Sulfate | (+) for Skeletal mm spasms, myositis |
| Zinc Oxide | (+) for Skin Ulcers |
| Tap Water | (Alternating polarity) for hyperhidrosis |
| Copper | (+) for Fungus (Athletes foot) |
| What is Iontophoresis? | electrical current is used to drive ions of various substances through the skin and into underlying tissue |
| What current is used for Iontophoresis? | low volt DC |
| What is transdermal ion migration? | When ions are delivered to the tissue as they are repelled by an electrode with the same polarity. |
| What depth below the skin does it deliver meds? | 6-20 mm below skin |
| CD (Current Density) is a concern for safety. What is the safe range for Iontophoresis? | CD = Current Amplitude/area of the electrodeusually 0.1 - 0.5 mA/cm2 |
| What may happen if you do not determine current density? | It could cause a burn/galvanic rash which develops about 5 min after tx |
| How can burns be avoided? | Buying commercially prepared electrodes. Use larger electrodes to prevent rash or burns |
| Does DC have active and dispersive electrodes? | Yes |
| How does Iontophoresis adapt to fluctuations in tissue? | There is a constant voltage output by adjusting the amperage |
| Common meds used | 1)Aneshetics-dental, ENT,lidocaine2)Analgesics3)Anti-inflammatories-most common in PT; Dexamethasone |
| Increased time = decreased/increased ion transfer | increased ion transfer |
| Increased time = decreased/increased impedance making an increased chance of burns. | decreased |
| Do hair follicles and sweat glands decrease impedance? | yes * |
| What are the factors if med are taken orally? | 1.metabolic breakdown of med is reduced because liver is bypassed.2.not absorbed in GI Tract3.med in concentrated in localized area |
| What are the factors if med is given through an injection? | 1.it is less traumatic2.less painful3.increased med in localized area can cause damage. |
| Alropine Sulphate | (+) for hyperhidrosis |
| Calcium | (+) for Myopathy, myospasm |
| Chloride | (-) for Sclerolytic, scar tissue |
| Glycopyrronium Bromide | (+) for Hyperhidrosis |
| Penicillin | (-) for Infected burn wounds |
| Poldine methyl sulfate | (-) for hyperhidrosis |
| Potassium Iodide | (-) for Scar tissue |
| Sodium Chloride | (-) for Scar tissue |
| Silver | (+) for Chronic osteomyelitis |
| What current is used for Iontophoresis? | Low V DC (Monophasic) |
