Abstract:
Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on the intracranial pressure in patients undergoing laparoscopic hysterectomy by measuring the optic nerve sheath diameter (ONSD) via ultrasound.Methods:Forty-two American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 18-60 yr, with a body mass index of 18-28 kg/m 2, scheduled for elective laparoscopic hysterectomy, were divided into 2 groups ( n=21 each) using a random number table method: control group (group C) and TEAS group (group T). In group T, TEAS was applied to the Yintang (EX-HN3) and Taiyang (EX-HN5) acupoints at 30 min before anesthesia, the stimulation used alternating dense-disperse waves at a frequency of 2/100 Hz, with the current intensity starting at 1 mA and increasing to the maximum tolerable level just below the pain threshold, and stimulation was maintained at the Hegu (LI4), Quanliao (SI18), and Fengchi (GB20) acupoints during surgery until the procedure was completed. Patients had electrode pads applied to the corresponding acupoints without electrical stimulation in group C. The ONSD was measured upon entry into the operating room (T 0), 3 min after anesthesia induction (T 1), 5 min after trendelenburg position (T 2), 30 min after trendelenburg position (T 3), 60 min after trendelenburg position (T 4), and immediately after the end of operation (T 5). Results:Compared to the baseline at T 0, the ONSD was significantly increased at T 3-5 in group C and at T 4, 5 in group T ( P<0.05). The ONSD was significantly lower at T 4, 5 in group T than in group C ( P<0.05). Conclusions:TEAS can reduce the intracranial pressure to some extent in patients undergoing laparoscopic hysterectomy.
