the observation on the motility function of gastro ntes- tinal tract after operation under acupuncture anesthesia (AA) was under- taken. It was discovered that after application of acupuncture for a long time

the post-acupuncture effect could alleviate the disturbance of gastro- intestinal function induced by operation and medication aud promote the post-operative gastrointestinal recovery. The results are seperately stated as follow: 1. The infuluence of acupuncture on the duration for initial release of gas from anus after operation. Usually the recovery of motility function of intestine is valualed by the duration for the initial release of gas from anus after operation. In the acupuncture group (Gr. Ⅰ)

the average duration is 12 hrs.

that of epidural anesthesia group (Gr. Ⅲ) 53.7hrs. The difference between the two groups is very significant (P<0.01). In the combined epidural and acupuncture anesthsia group (Gr. Ⅱ)

the average duration is 47.1 hrs

6.6hrs. earlier than Gr. Ⅲ with significant difference (P<0. 05). For investigating whether styles of operation influence the duration for the initial releasing of gas after operation

those cases With gastro- duodenostomy (Billroth Ⅰ)

in which traction during operation was consi- dered to be less

were listed in Table Ⅱ. After comparison

it was clear that the average postoperative duration in Group Ⅰ was still shorter than that of Group Ⅲ (P<0. 01). The du- ration in Group Ⅱ was stiII in between the other two groups. This result suggests that acupuncture produces a predominant influence on the duration for postoperative initial release of gas

and the duration is unrelated to the style of operation. 2. The Influence of Acupuncture on Postoperative peristaltic Sound: The auscultation and sound recording of intestinal perlstalsis for 4 hrs. After operation were analyzed for the 8 groups. If 0-5 times/10 min. of peristaltic sound was taken as remarked depression

then the percentage of dapression in Gr. Ⅲ was the highest. It occupied 78% of this group. Those for Gr. Ⅱ and Gr. Ⅰ were 28. 1% respectively. The differences among the three groups were very significant (P<0. 01). The sound of intestinal peristalsis began to recover to different degrees one day after operation in the three Groups. The recovery in Gr. Ⅰ was the most prominant. While G. Ⅲ was the slowest one in the three groups. If the change of peristaltic sound in combination with the duration for post-operative initial release of gas was analyzed

It was found that the peristaltic sound were significantly depressed in the majority of the cases whose durations for post-operative initial release of gas were over 55-60 hrs. The depression of peristaltic sound was milder for those whose post- operation initial release of gas were shorter than 48 hrs. If the relation- ship between the change in peristaltic sound at the day of operation and the duration for post-operative initial release of gas in the three groups was analyzed

it was found to be negatively interrelated

i.e. if the peris- taltic sound was much depressed at the day of operation

then the du- ration for post-operative initial release of gas was longer. If depression of peristaltic sound was little at the day of operation

then the duration for post-operative initial release of gas is shorter. These results indicate that the sound of intestinal motility is intimately related to the duration for post-operative initial release of gas. Acupuncture can decrease the de- gree of depression of peristaltic sound after operation. That may be the main cause why the post-operative recovery of intestinal peristalsis is qui- cker and the duration for post-operative initial release of gas is shorter in EA+AA and AA groups. 3. The Influence of Acupuncture on Postoperative EIG: From the analysis of slow waves of EIG on body surfaces of the ca- ses in the three groups

it can be seen that the change in EIG is also in accord with that of intestinal peristaltic sound. The degree of depression in EIG is milder in Gr. Ⅰ and Gr. Ⅱ

and the duration for depression is shorter. The degree of depression in EIG is stronger in Gr. Ⅲ

and the duration of depression is longer. From picture 1 and 2

it is clear that the depression of EIG for those under AA is mider

and activity of their EIG is recovered partially after operation. The amplitude of EIG increases evidently 5 hrs. after operation. The EIG is evidently depressed in those under EA. EIG did not recovery to normal 5 hrs. after operation. It is also found that the amplitude of EIG waves increses evidently after the inducing period of acupuncture

so the influence of adjuvant drug atropine is less. While the influence of atropine in EA is quite remauked. In continuous observation of postoperative EIG

it is discovered that in those who have earlier recovery of EIG

durations for postoperative initial release of gas are also shorter. Otherwise the durations are longer. The above mentioned results indicate that the influence of acupuncture on EIG probably is the main factor that promotes the changes in intes- tinal sound or motility and duration for postoperative initial release of gas. 4. The Influence of Acupuncture on Postoperative EGG: In conti- nuous monitoring of postoperative EGG on boby surface of patients with pneumonectomy

it is found that the frequency of EGG after operation under AA has no obvious change(P<0.05). While that under drug anesthe- sia has an evident decrease. There is no recovery even 4 hrs. after ope- ration. In comparison with preoperative EGG

the differeence is very sig- nificant (P<0. 01). The result indicates that drug anesthesia possesses an inhibitory effect on postoperative EGG. While in AA

there is no such inhibition (Table Ⅲ).
