It is a very important problem for the preoperative anesthetic management to relieve anxiety and fear of surgical patients. We observed the preoperative emotional states in relation to pain threshold, pain tolerance and reaction to experimental pain by appling the signal detection theory. The following results were obtained in the preoperative states which were compared with the resting states in the control group, the diazepam group and the relaxation group.(1) The control group showed no changes of pain threshold, tolerance and sensitivity(d') but demostrated a significantly increased bias response (c).(2) The diazepam group showed unaltered pain threshold, sensitivity (d') and response bias (c), but decreased pain tolerance.(3) The relaxation group showed a decrease in pain threshold and tolerance but an increase in sensitivity (d') to stimulation and a decrease in bias response (c).The results indicate that observation of the sedative effect is useful in order to understand the preoperative anxiety in reaction to experimental pain when it is done not only by the measurement of the traditional threshold and tolerance bu by the evaluation of (d') and (c) in the signal detection theory analysis.
