摘要
目的观察经皮穴位电刺激对七氟烷全麻下新生猪脑电图(EEG)的影响。方法将12头新生猪随机分为经皮穴位电刺激组(T组)和对照组(C组)。T组在麻醉前给予经皮穴位电刺激30 min,C组则不给予任何干扰。2组均采用高浓度(8%)七氟烷进行麻醉诱导,3.5%维持,七氟烷麻醉1 h停止吸入。记录插管及拔管时仔猪的心率、麻醉诱导和维持期间脑电图棘波的振幅和频率。结果 T组插管、拔管时的心率明显低于C组,差异有统计学意义(P<0.05)。麻醉诱导期间T组棘波频率和振幅低于C组,麻醉维持期间T组棘波频率和振幅均低于C组,差异有统计学意义(均P<0.05)。结论七氟烷麻醉期间新生猪EEG可出现棘波,而经皮穴位电刺激可有效降低棘波的发生率。
Objective To investigate the effects of transcutaneous electrical acupoint stimulation （TEAS） on electroencephalography （EEG） in piglets anesthetized with sevoflurane. Methods Twelve piglets,aged three to seven days,weighing 1.5 to 3.5 kg,were randomly divided into 2 groups：TEAS （group T,n = 6） and control （group C ,n = 6）. Group T received continuous TEAS at points baihui and tianmen for 30 minutes. Anesthesia was induced with 8.0% sevoflurane over 3 minutes and maintained with 3.5% sevoflurane in both groups. The changes were observed on EEG. Results The heart rates （ HR ） at intubation and extubation were lower in group T than group C （P 〈 0.05）.Compared with group C, the EEG spike frequency was lower in group T during anesthesia induction and maintenance （P 〈 0.05）. Conclusion Sevoflurane can induce EEG spikes in piglets,which can be reduced by TEAS.
