以往我们曾在胃大部切除术病人术前、术中记录了病人指(趾)血管容积脉搏波幅的变化.在动物实验中记录了电刺激内脏大神经时腹肌肌电反应

证明了这两项生理指标对探讨內脏疼痛反应的规律和评定临床腹部手术的针麻效果上具有一定价值.本文利用胃牵拉反应的动物模型记录了腹肌The responses of the stomach traction involving the augmentation of the abdominal EMG

the increase of the efferent bursts of the recurrent laryngeal nerve and the diminution in amplitude of the volume pulse wave of the ear were partly inhibited by acupuncture. From the observation it is suggested that the impulses arising from the stomach traction are conveyed not only in the great splanchnic and vagus nerves

but also by way of the abdominal somatic nerves

which innervate the parietal peritoneum. The pulling response was more prominent from par pylorica than other portions of the stomach. It could be decreased obviously when the stomach was tracted outside of the abdominal cavity or the parietal peritoneum anaesthetized locally with procaine. It is therefore concluded that diminishing the stimulation on the parietal peritoneum as less as possible is very important for a good acupuncture anaesthesia in abdominal surgery.
