Iontophoresis-Bon #174409

QuestionAnswer
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)
