Abstract: 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.
