Effects of Transcutaneous Electrical Acupoint Stimulation on Stress Response during Intubation and Extubation in Patients Undergoing Video-Assisted Thoracoscopic Surgery: A Prospective, Randomized Controlled Trial

Figure 2

Heart rate and mean arterial pressure changes in the two groups. (a) Mean arterial pressure. (b) Heart rate. The patients in the TEAS group received electroacupuncture stimulation of bilateral Hegu (LI4), Neiguan (PC6), Lieque (LU7), and Chize (LU5) acupoints from 30 min before anesthesia to the end of surgery. The patients in the control group were not given the stimulation. TEAS, transcutaneous electrical acupoint stimulation; T0, 30 min before the induction of anesthesia; T1, immediately after intubation; T2, 5 min after intubation; T3, immediately after extubation; T4, 5 min after extubation. Data are presented as mean ± standard deviation (). versus T0; versus the control group.
