chapter 6 Nondrug Techniques: Iatrosedation and Hypnosis
In Chapter 3, the concept of sedation was described using the terms psychosedation, iatrosedation, and pharmacosedation. Definitions of these terms are presented at this time to provide groundwork for the remaining sections of this book.
The overall concept of sedation was originally defined as “the calming of a nervous, apprehensive individual, through the use of systemic drugs, without inducing the loss of consciousness.”1 Although this definition is essentially accurate, it requires further clarification. This is so because clinical techniques exist that act to diminish a patient’s fears and anxieties toward dentistry and surgery without the use of drugs. In addition, the term sedation, implying relaxation of the mind, is too broad of a term because it is possible to specifically “relax” or “sedate” the function of other organs (e.g., the heart [through the use of β-blocking drugs]). Therefore the more specific term psychosedation is suggested when discussing the management of fear and anxiety. The term psychosedative describes a drug capable of producing relaxation of the patient’s mind (e.g., central nervous system [CNS] depression). The two major categories of psychosedative techniques are iatrosedative techniques and pharmacosedative techniques.
Iatrosedation and hypnosis are discussed in this chapter because they are both important components of the dentist’s armamentarium against pain and anxiety. The reader interested in the other techniques previously listed is referred to specific references cited for each: acupressure,2 acupuncture,3 audioanalgesia,4 biofeedback,3,5 EDA,4,6 and electrosedation.7
IATROSEDATION
Iatrosedation: The relief of anxiety through the doctor’s behavior.
This definition of the term iatrosedation was formulated by Dr. Nathan Friedman, for many years the chairman of the Section of Human Behavior at the University of Southern California School of Dentistry. The word is derived from the Greek prefix iatro, meaning “pertaining to the doctor,” and the word sedation, meaning “the relief of anxiety.”8
Two classic studies illustrate the importance of human behavior in the control of pain and anxiety. In the first, Egbert et al9 demonstrated the value of the preoperative visit by the anesthesiologist to patients about to undergo surgery the next day. Patients were placed in one of three groups.
A second study by Egbert10 once again demonstrated the value of iatrosedative techniques in patients undergoing surgery. Patients scheduled for abdominal surgery were placed in one of two groups.
In the motion picture The Doctor,11 a successful surgeon falls ill and enters into the contemporary health care system as a patient experiencing, as never before, the trials and tribulations that befall patients every day in the hospitals and medical centers of America. Through his negative experiences, the physician learns the value of communication and the importance of empathy in dealing with patients. This award-winning and highly successful film was based on a true story. Incoming residents in family practice medicine at the Long Beach (Calif.) Veterans Administration Hospital begin their hospital career as patients admitted to the hospital, undergoing the routines all patients face (hospital gowns, blood tests, impersonal attitudes by hospital staff).12 Much of the commercial success of The Doctor was thought to be that audiences (all potential patients) believed that the message of the film struck home. The medical profession, to its credit, has recognized that the great emphasis placed in medical education upon the “scientific process” leads to the isolation of the physician from the patient and has begun to take steps to right the perceived wrongs. In a 1992 paper, Spiro13 states that “medical students lose some of their empathy as they learn science and detachment, and hospital residents lose the remainder in the weariness of overwork and in the isolation of the intensive care units that modern hospitals have become.” Medical schools have begun to modify their curricula, including in them new programs on communication and human behavior, designed to prevent the impersonalization of the physician.14
Similar programs have been in place for years in many dental schools throughout the United States and other countries. Yet in the highly competitive world that is dentistry today, it is often the patient who gets lost in the shuffle. I abhor the increasing use of the term client when discussing our patients. The importance of effective communication among the dentist and staff and patient can never be overemphasized. Interestingly, in the venue of continuing dental education, among the most popular programs offered are those in practice management—how to have a successful dental practice.15 The theme of communication is paramount in all these programs.
