Summary

During endotracheal tube insertion under general anesthesia, sympathetic nerve activity increases, which leads to increased heart rate, increased blood pressure, and increased catecholamine levels in the blood. It is important for patients to maintain hemodynamic stability during anesthesia induction and ultimately mitigate the cardiovascular stress response associated with tracheal intubation.

Transcutaneous Electrical Nerve Stimulation based on Wrist-Ankle Acupuncture theory (TENS-WAA) is a non-invasive pain treatment method, It has the advantages of easy wearing, concentrated treatment site, safe treatment and needle-free. To date, due to the lack of large-scale clinical use of TENS-WAA, only a few studies have reported the use of TENS-WAA for postoperative pain rehabilitation, especially for perioperative pain management. The aim of this study is to evaluate the median effective dose (ED50) of TENS-WAA for remifentanil inhibiting responses to tracheal intubation under general anesthesia, and to provide a reliable basis for its clinical promotion.

Conditions

  • Perioperative Analgesia
  • General Anaesthesia

Interventions

OTHER

TENS-WAA

Before anesthesia induction, two paired of electrode pads will be placed on the upper area 1 and 2 with the skin of the treatment area exposed, and the upper and lower juxtaposition method will be adopted. The electrodes were placed close to the skin and connected with TENStem eco basic (Wuxi Jiajian Medical Device Co., Ltd.). Upper area 2 is at the middle of the palmar side of the forearm, between the palmaris longus and flexor carpi radialis.Upper area 1 is between the ulnar border on the little finger side and the flexor carpi ulnaris tendon.Stimulation parameters of TENS-WAA are alternating dense-disperse wave with a frequency of 2Hz and a pulse width of 200μs, and a frequency of 100Hz with a pulse width of 150μs, alternating every 3 seconds ，intensity required to reachthe maximum tolerable level without causing pain, continuous stimulation until the end of surgery.

OTHER

non TENS-WAA

Before anesthesia induction, two paired of electrode pads will be placed on the same position without current stimulation.
