To realize the intraoperative intestinal electromyogram (EMG) which may have a reliable role in assessment of intestinal viability. Thirty-two albino rabbits were divided into four groups randomly. An isolated ischemic bowel loop in 10 cm length was made in each rabbits. The clamp and rubber bands were released at intervals of 1,2, 3 and 4 hours in different groups. Bipolar EMGs of the ischemic loop were taken before, just before the end of and 30 minutes after the clamping. The involved intestines were observed...

To realize the intraoperative intestinal electromyogram (EMG) which may have a reliable role in assessment of intestinal viability. Thirty-two albino rabbits were divided into four groups randomly. An isolated ischemic bowel loop in 10 cm length was made in each rabbits. The clamp and rubber bands were released at intervals of 1,2, 3 and 4 hours in different groups. Bipolar EMGs of the ischemic loop were taken before, just before the end of and 30 minutes after the clamping. The involved intestines were observed under light-and electro-scope 48 hours after the first operation. In all loops encountering over three hours ischemia the postreperfusion BER (Basic electric rythm) frequency(fc) dropped significantly compared with those (fa) before ischemia (P<0. 05). However, in those ischemia less than three hours, the frequency didn't change obviously. there was positive correlation between the decrement of BER frequency and pathological degree (γ= 0. 507). The wave amplitude decreased after reperfusion. The operative EMG plays a role in assessing the viability of ischemic bowel.

为探讨术中肠肌电图法(EMG)对肠活力的评价作用,将 32只家兔随机分为4组,选取10cm长末端小肠制成肠袢肠缺血模型,分别造成缺血1、2、3和 4h、双极银电极记录缺血前(a)、缺血末(b)和再灌注30 min(c)时的 EMG变化。 48h后再次开腹,取原缺血肠段作光镜和电镜观察。结果显示:缺血≥3 h的肠段,BER的fc明显低于 fa( P<0. 05);缺血<3 h的肠段,fc变化不明显;(fa-fc)的变化与 48 h后肠的病理损伤程度呈正相关(γ=0.507);EMG振幅在再灌注后降低。表明EMG能用于术中评价缺血肠活力,对预测术后近期肠管生存质量有一定的临床价值。

Objective To discuss application value of intestinal electromyography in patients with hepatic cirrhosis and to observe intestinal myoeletric activity.Methods There were 65 cases of hepatic cirrhosis in expermental group and 30 cases in control group. All the cases were recorded body surface intestinal electromyography using gastrointestinal myoelectric analyzer(WCDF-4B, Hefei , P.R.China). The parameters included average peak range-Ap, main frequency-Fp, average over zero frequency-Fz and special wave form were surveyed.Results Sharp higher Fz abnormal rate and emergence rate of special wave form in hepatic cirrhosis group were higher than in control group,P<0 01;But no statistic difference for Ap, Fp between two groups, P>0 05.Conclusions In hepatic cirrhosis group,Fz was much higher than that in control group. And the intestinal myoelectric activity increased in the patients with hepatic cirrhosis,which represented by appearance of characteristic wave form that was frequent micromigration wave as well as load wave. Those changes accounted for heighten and irregularity of excitability intestinal myoelectric activity. Moreover, it will increase for the incidence of abnormality of intestinal myoelectric activity along with damage degree of hepatic function. Intestinal electromyography is a reliable method to judge intestinal myoelectric activity, the method has characteristics of harmless,free pain, convenient, safty and steady.

Objective To explore the effects of intestinal infection and stress on gut motor function in rabbits Methods Animals were divided into groups as the follows: control, stress alone, intestinal infection alone, intestinal infection plus stress, and post infection plus stress (exposed to stress at 1 week or 2 week after infection). The rabbits were exposed to cold restraint stress at 6℃ for 6 hours. E. Coli 015 at a concentration of 1 5×10 9-4×10 10 was introduced through nasogastric tube to induce intestinal infection in animals. Gut motor function was evaluated by measuring myoelectric activity with microelectodes implanted into the intestinal wall and it was expressed as the percentage of experimental over control of motor index (average area under curve of contractile activity/per 10 sec.). Histology and NADPH stained enteric nerves of the terminal ileum and distal colon of each batch of animals were studied Results Cold restraint stress at 6 hrs could significantly enhance the myoelectric activities of terminal ileum and distal colon in animals. The motor index in the rabbits of intestinal infection plus stress group was higher than those in the stress alone or infection alone group at 1 week and 2 week after infection. Induction of stress to the animals at 1 week or 2 weeks after infection significantly potentiated the response of muscle contraction at the terminal ileum and distal colon (motor indexes: 452.96 vs.35 14% and 405 19 vs.12 74% respectively,P<0 01). There were no structural changes in the lamina propria at two weeks after intestinal infection plus stress, and a reduced score of NADPH stained nerves in the myoenteric plexus of the ileum and colon was also noticed Conclusions Intestinal infection alone is not able to produce bowel dysfunction under our experimental conditions. But the motor response of the pre infected gut could be significantly augmented by cold restraint stress. Therefore, our study provide new evidence for the hypothesis that status of the central nervous system (if stressful event is present at time of initial bowel infection) is important in predicting whether persistant functional bowel disturbance will develop after acute bowel infection. Also, a depletion of NO in the ENS is possibly involved in the intestinal motor disorder
