4.2 Electrotherapy
Placing electrodes near the chest can increase the risk of ventricular fibrillation.
When performing iontophoresis, the drug used may have an analgesic effect and pain
sensitivity is reduced as a result.
Stimulation current can have a stimulating effect on insulin release. This may result in
hypoglycaemia in diabetic patients.
The electrical stimulation or materials used can cause skin irritation or hypersensitivity in
sensitive patients. This can be reduced through the use of an alternative electrode material or
by changing the position of the electrodes.
Stimulation may not be used:
• over the carotid sinus nerve
• over the neck and mouth
• transthoracically
• transcerebrally
• over swollen, infected, inflamed areas
• over or near cancerous lesions
In patients who tend to develop haematomas, treatment should only be performed after the risk
has been assessed and found negligible.
The above warnings apply to electrotherapy in combination with the vacuum unit.
When the intensity controller is turned up high, currents above 10 mA eff may flow or
there may be voltages over 10 V at the output sockets.
