Stimuplex® HNS 12 – Localisation and anaesthesia in one

Local anesthesia is the anaesthetisation of a single part of the body.  During this procedure the ability to feel pain in that part of the body during an operation is switched off.  The patient usually remains conscious.  This process relies upon the ability to locate exactly the nerve which is to be anaesthetised.  To facilitate this the device emits a weak, yet effective, pulse of current into the tissue via the needle.  As the needle approaches the nerve, the patients experiences a contraction of the muscle.

As soon as the surgeon has localised the nerve, he is then able to inject an anesthetic into the area around the nerve through a tube which is attached to the needle.  A moment later, and the required area is numb and the operation can commence.

Local anesthesia has proven to be a safe procedure.  The STIMUPLEX® HNS 12 offers the possibility to combine nerve localization and anesthesia using the same device, thus minimizing the risk of complications such as nerve damage.  Its application means that, in most cases, a general anesthetic and the associated risks is not required.
