As humoral factors have been considered to take part in the effectiveness of acupuncture anesthesia and as microcirculation may reflect the fine changes of neurotransmitters and physiological chemical substances, their relationship was investigated in order to detect whether the acupuncture stimuli have played some regulatory role in microcirculation.
The subjects observed were patients during thyroidectomy under acupuncture anesthesia with special observation on the changes in nail-fold microcirculation during the process of acupuncture anesthesia. Examination was carried out for changes in the number, calibre, length, visibility of the capillary loops, status of blood flow, and the clarity of the microscopic field.
Needling was done at Hegu and Neigua.
The effectiveness of acupuncture anesthesia was divided into 4 grades: excellent, good, poor and bad.
We found that the nail-fold microcirculation showed a regular pattern of change in the process of acupuncture anesthesia.
In comparison of the finding in excellent cases with those with poor effects, the microcirculation of those cases with excellent effect was very clear in microscopic field, no change in number and length of loops, normal calibre of loops and normal rate of blood flow (óI sec). And the microcirculation of those patients with poor effects showed changes, such as obscure morphology of blood vessels, shortening, decreased number or invisibility of the loops and the blood stream was sometime invisible owing to the interruption of blood flow.
The changes of skin temperature and vascular volume wave of finger tips were also observed during acupuncture anesthesia. In cases of excellent effect both skin temperature and vascular volume wave were increased.
The above results tend to show that there is a close relationship between the change of nail-fold microcirculation and the effects of acupuncture anesthesia, we also consider that microcirculation is one of the criteria helpful in determining the effectiveness of acupuncture anesthesia.
