Distribution of an explanatory note concerning the risks of anesthesia prior to preanesthetic evaluation

: To make the public aware of the risks of anesthesia, we prepared an explanatory note composed of 634 Japanese characters or of 248 English words. The incidences of fatal anesthetic complications over a five-year period in 2,358,642 anesthetics in 741 Certified Training Hospital belonging to the Japanese Society of Anesthesiologists were cited in the explanatory note. Patients were asked to read and sign the explanatory note prior to agreeing to surgery. After patients having received this general information about surgical and anesthesia risks, surgeons then apply to the Department of Anesthesiology for their anesthetic management. Thereafter, responsible anesthesiologists visit and evaluate patients, and explain common as well as specific anesthesia risks to each patient. A survey by mailing questionnaires regarding this explanatory note and anesthesia risks sent to patients, who had read and signed the explanatory note, revealed that the patients were generally satisfied with the content of the explanatory note. This system may help patients, surgeons and anesthesiologists to recognize anesthesia risks on the same basis.
