休克是临床常见危急综合症

较为近似中医的脱证

失血性休克多见于中医的血脱

津脱、继之亡阴

出现“气滞血瘀”气血失调的症状

及时采用一些急救措施来调节机体的阴阳气血达到益气救阴回阳救逆是非常重要的

应用针刺治疗法在抢救休克特别是促使血压回升有一定作用。针刺对失血The objective of this study was to observe the effects of hemo(?)rhagic shock and electroacupuncture (EA)at “Renzhong” following shock on brain spontaneous and evoked potentials of rabbits;and further to analyse the regu- latory function of acupunctre on brain function in the rabbits with hemorrhagic shock. Rabbits were anesthetized with chloralose-urethan.The left peroneal nerve was placed on a pair of electrode for stimulation;the recording electrode was passed through skull and placed on the right cerebral somatosensory area.An arterial catheter fulled heparin was placed in the right femoral artery.Mean arterial blood pressure (BP) and electroencephalogram (EEG) were separately recorded on a multi-purpose physiological recorder:and EEG activity was put into a cassette data recorder for EEG power spectral analysis.Somatosensory evoked potentials (SEP) were averaged on Medical Data Processor

then reco- rded by X-Y recorder. The results were as follows: Among 30 rabbits

at the initial stage of shock

dysrhytemia of EEG appeared in 9 cases

EEG were no significant change in 13 cases

EEG showed slight improving in 6 cases;at maintaining shock for one hour

dysrhythmia of EEG appeared in 20 cases

EEG were no significant change in the rest. After EA at“Renzhong”

EEG showed clearer improvement in 24 cases;dys- rhythmia still appeared in 4 cases.EEG power spectrals were analysed on 5 rabbits.During hemorrhagic shock

normal theta rhythm (4-7Hz) was gradu- ally disappeared and the area of faster delta rhythm (2-3Hz) power spectral was gradually decreased;And after EA

the power spectral area of theta and faster delta rhythm was increased. among 26 rabbits

at maintaining shock for one hour

the amplitudes of SEP were decreased and some components of SEP disappeared or wave form was changed in 23 cases;after EA

mean arterial pressure was significantly increased (P<0.05)

the amplitudes of SEP were picked up or wave form recovered in 17 cases.The EEG improvement was close related to a rise in blood pressure. The results indicated that electroacupuncturing “Renzhong” could rise BP of the rabbits with hemorrhagic shock and improve their brain function to a certain extent.There was close relation between EEG improving and BP rising.
