Injex. Needle-free anaesthesia
Without needing to use a needle, the liquid penetrates the subcutaneous tissue through a high pressure injection. A spring inside the injector produce the elastic force necessary to liberate the established volume of anaesthetic, through a micro-pore at the tip of the ampoule.
Despite the small quantity of anaesthetic used, the effect is sufficient for the work to be undertaken. On the other hand, the painless sensation of the technique is valuable in the majority of cases and, above all, as is the reduction in anxiety produced by the needle. This is especially effective when we treat children, as by not seeing a needle they remain calm and the result, at both patient and medical level, highly positive.
A negative aspect is the noise produced by the “shot”, which may induce fear at the moment of the injection. However, this fact can be substantially reduced if a prior demonstration is made for the patient so that he or she may hear the noise it makes.
In relation to pain or symptoms after 24 hours, they are no greater than those produced by conventional anaesthetic administered with a needle.
In short, it is a good system which helps to relax the patient, thereby ensuring our work is more effective.
