This study attempts to clarify: 1) The effectivity of suggestion on cutaneous sensation (electric touch, electric pain); 2)The relation between suggestibility and the effects of acupuncture anaesthesia. 53 patients for lung resection were used as subjects.
The results were as follows:
1. The suggestive stimuli were word induction and observation of the amplitude scale of the osilloscope. After suggestion, electric touch and pain threshold increased by an average of 28.1% and 20.3% respectively (P<0.001).
2. The suggestibility of pain was highly correlated with the sensitivity of pain, i.e. the more sensitive, the more suggestible. The suggestibility of electric touch and electric pain as a whole, being highly corelated with the sensitivity of the 4 cutaneous sensations compounded, also showed that the more sensitive patients were the more suggestible ones (P<0.01).
3. The increment of suggestibility had no significant correlation with the effects of acupuncture anesthesia (P>0.1), but it appeared that among patients showing favourable effects they were somewhat more suggestible.
Suggestibility had no relation to the physiological prediction test of acupuncture results which had high consistency with the actual effects. Moreover, it had a high correlation with the compound cutaneous sensitivity, which had a high negative correlation with the actual acupuncture results. Thus it may be inferred that suggestion is not the dominant affecting factor in the acupuncture anesthesia effect.
4. The degree of patient's trust in the opeartor and in acupuncture anesthesia had a high correlation with suggestibility, patients showing more trust were the more suggestible ones. The degree of trust itself had no significant correlation with the effect of acupuncture anesthesia, but there were more patients showing trust among the group with good effects.
5. According to these results we have the idea that suggestion is not the main factor which determines the effect of acupuncture anesthesia, yet it exerts a moderate influence in increasing or decreasing the effect.
