Again and again we hear about hypnosis being used during operations or in dentistry to reduce anxiety and pain. It is true that hypnosis can completely replace anesthesia. However, as a rule, hypnosis and anesthesia tend to take place together, usually due to time constraints. This is because the use of hypnosis requires preparation and also permanent monitoring by a hypnotherapist during a treatment.The challenge is to maintain hypnosis equally over a long period of time, it is more susceptible to disturbances than anesthesia and due to the duration of a treatment it is too expensive for most procedures, as a hypnotherapist must be present during the entire time. Partial drug therapy along with hypnosis is therefore more commonly used. The combination of a reduced anesthesia, for example local, and hypnosis has proven to be very effective. For mild and uncomplicated procedures, hypnosis is also sufficient as a sole method to eliminate and reduce pain.
