在出血性休克和出血性休克并发休克肺两过程,用电生理仪记录了植物神经的电活动。在单纯休克过程:颈交感神经传出冲动减弱,颈迷走神经传入冲动、内脏大神经和减压神经的传出冲动均见增强;阻断迷走神经传入冲动后,颈交感神经放电活动立即变为增强。在休克并发休克肺时:颈交感神经电活动不再是减弱而是增强;其余三神经干电活动仍为增强,而且较单纯休克时增强得更为明显。本文对上述诸项变化的发生和意义作了分析和讨论。
In hemorrhagic shock and hemorrhagic shock complicated by shock lung two processes, recorded by electrophysiological autonomic electrical activity. During the simple shock process, the sensory impulse of the cervical sympathetic nerve was weakened, the afferent impulses of the cervical vagal nerve, the visceral major nerve and the decompressive nerve were enhanced. After the vagus nerve was implanted, the activity of cervical sympathetic nerve discharge immediately became Enhanced. Shock in shock when the lungs of shock: cervical sympathetic electrical activity is no longer weakened but increased; the remaining three nerve activity is still enhanced, and more significantly enhanced than when shock alone. This article analyzes and discusses the occurrence and significance of these changes.
