In a context where some individuals are allergic to pain killers/anesthetics and still would have to undergo surgical procedures to get rid of their medical problems, there has been a growing acceptance on the part of medical fraternity, whether it is physicians or surgeons, to use hypnosis as an alternative for a number of procedures (e.g. childbirth, removal of stones in the kidney) which otherwise involve surgical procedures. Hypnosis has been used as an effective procedure in these and a number of other instances from time immemorial but it started gaining scientific acceptance in the USA since it was promoted on a scientific basis by the American psychiatrist Milton Erickson as something falling within the discipline of psych-therapeutic practice. In that sense the use of hypnosis in alleviating the pain of those who cannot tolerate pain killers is real and has further been found to be of considerable utility in preventing the undesirable effects of surgical procedures. For instance, when a subject is injected with anesthetics it causes the tissue to swell which in itself poses as an issue for the surgeon to handle as a problem in addition to issues arising out of surgery. In addition, it is possible some people have a psychological fear of needles which may prevent them from seeking remedies to other problems consequent to which their conditions could worsen. It is erroneous to believe that hypnosis can be used in all cases of surgery because in cases of major surgeries still it cannot be a method but still there is growing evidence to show that at least in respect of certain other cases it is being used in an increasing manner. Thus, Marie-Elisabeth, an anesthetist attached to Leige University Hospital located in Belgium has been using hypnosis on a regular scale for the removal of thyroid gland successfully. Her patients have been reporting of a pleasant experience because they have experienced lesser post-operative pain. Furthermore, they were in a position to return to work faster than those patients who underwent standard surgical procedures (e.g. sedation) for same type of surgery. The additional benefits that accrue with the use of hypnosis relate to savings of cost for hospitals, insurance companies and a lesser burden on the exchequer in regard to health care.
How do things work in hypnosis in this regard? It may be erroneous if one thinks that individuals under hypnosis can be made to do things which they otherwise cannot ordinarily do. On the contrary what happens during hypnosis is that the subjects transit to a state of highly focused attention, wherein while on the one hand, there is a constriction of peripheral awareness, on the other hand, there takes place a heightened responsiveness to social cues. It can be compared with any other daily events where people get totally absorbed which could be compared to situations of their watching an interesting movie or reading a book. Scientific explanations of how people under hypnotic state of mind can undergo such surgical procedures comfortably have started to emerge. For instance, Schulz-Stubner, team leader attached to the Aachen University, Germany measured the brain activity through functional magnetic resonance imaging (fMRI) scans of 12 otherwise healthy volunteers who underwent treatment by using hypnosis without having recourse to surgical procedures. The results had shown that hypnosis stopped the pain signals that otherwise travel from the nerve cells to the primary somatosensory cortex, which serves as the fundamental source from where the stimuli of pain gets elicited. When the subjects experimented were under a hypnotic state, the pain signals fizzled out within the subcortical area resulting in the disappearance of what one otherwise terms as the ‘ouch effect’.
However, caution is the watchword we have to keep in mind while discussing about the use of hypnosis in surgery for it is not useful for everyone. For instance, experts caution that it should not be resorted to in those who are suffering from certain psychiatric disorders as acute depression. This is because such people have a lesser ability to differentiate between reality and a hypnotic suggestion. Similarly, it should not be tried when the affected individuals are under the influence of alcohol or those who have not been fully under gone a premedical diagnosis. They also point there is a percentage of population, say about 5% who cannot that easily be hypnotized either because either they cannot imagine or have a concentration deficit or suspect the very concept of hypnosis.
It needs to be noted that emerging theories of hypnosis are multi-faceted in nature. For this reason, it belongs to both academic as well as practice oriented domains. For example academic scholars as Ivan Pavlov theorized it as similar to ‘partial sleep’, Morgan suggested it as a process of enhancing or contracting the activity of nervous system through the use of feedback loops. On the other hand, Baker and Wagstaff have taken a different stand by arguing that hypnosis is a form of learned social behavior founded on relaxation techniques, social compliance, and suggestibility. From a practice angle, Benton suggests that hypnosis offers quantifiable health benefits by promoting goal directed behavior through creating an emotional state conducive to bringing about positive changes in health and wellbeing.
The above discussions go to show that we do not still have a comprehensive picture of biological mechanisms to demonstrate in an unambiguous manner as to how hypnosis works on individuals thus still making it a mysterious science. Nonetheless, however mysterious it may be, there is no doubt of the fact that hypnosis has significant amount of scientific temper attached to it. This stretches it far beyond the spiritual realm without at the same time divorcing it from spirituality. Stated otherwise, it merits a place in the field of tangible practice and its practical value can significantly be enhanced if we could extend the research to multidisciplinary areas for a better academic and social understanding.
