【摘要】 <正> 对于心理因素在针刺麻醉中的作用,人们的看法殊不一致。有关情绪状态,暗示等心理因素对针麻效果的关系,已有过一些探讨。在我国针刺麻醉的大量临床实践中,多数单位在术前对病人均作“解说”工作,主要内容包括介绍针麻的优越性及尚存在的缺点,术中主要步骤有何感觉,以及应如何配合等。病人的这种“思想准备”对针麻效果有何意义,是否必要,这是一个应更多还原

【Abstract】 The purpose of thie study was to explore the influence of preopera-tive explanation on the effect of acupuncture anaesthesia.48 normal subj-ects were divided into readiness and non-readiness groups according topreexperimental instructions and the presence or absense of advanced in-formation of the stimulation applied.The two groups were matched accor-ding to sex,age,as well as their sensitivity of pain and acupuncture.The results were as follows:1.Pain feelings and G.S.R.responses to stimuli of the non-readinessgroup were greater than those of the other group,especially in sensitivesubjects.The evoked responses of pulse amplitude and the compoundedpulse,respiration and G.S.R.responses were different between the twogroups only in the sensitive subjects,showing that the sensitive subjectsin the non-readiness group responded more strongly.2.Both the pain feelings and the compounded evoked physiological re-sponses of the sensitive subjects were significantly higher than those ofthe non-sensitives in both groups.3.The results show that knowledge or mental readiness of acupunc-ture analgesia,i.e.the time,quality,feeling of stimuli,played only amoderate role in acupuncture analgesia.It seemed that prior-explanationof acupuncture had some significance,but its effect was limited and variedwith subjects.更多还原
