针刺麻醉的大量临床实践和实验研究已经证明

针刺具有调整和镇痛作用。可作为麻醉的手段之一。但心理因素

如其中的暗示作用

在针麻中有何意义

还存在不同看法。国外有人认为

针麻就是一种催眠暗示性的麻醉

多数人意见相反

有人进而用实验证明其机理是不同的。我国于1973年即有工作看到

暗示感受性高的人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 anesthesia. 53patients 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 oscil-loscope. After suggestion

electric tough and pain threshold increased by an average of 28.1% and20.3% respectively (P<0.001). 2. The suggestibility of pain was highly correlated with the sensitivity of pain

and the suggesti-bility of electric touch and electric pain as a whole

being highly correlated with the sensitivity of the4 cutaneous sensations compounded

also showed that the more sensitive patients were the more sugge-stible ones (P<0.01)

and that the compound cutaneous sensitivity negatively correlated with the act-ual acupuncture results. 3. The increment of suggestibility had no significant correlation with the effects of acupunctureanaesthesia (P>0.1)

but it appeared that patients showing favourable effects were scmewhat more sug-gestible. 4. The degree of patient's trust in the operator and in acupuncture anesthesia had a high correlat-ion with suggestibility. Patients showing more trust were the more suggestible ones. The degree of trustitself had no significant correlation with the effect of acupuncture anesthesia

but there were more pa-tients showing trust among the group with good effects. 5. According to these results a view is given that suggestion is not the main factor which determi-nes the effect of acupuncture anesthesia

yet it exerts a moderate influence in increasing or decreasingthe effect.
