Intracranial aneurysm (IA), a cerebrovascular disease with high mortality and disability rates, is a tumor-like protrusion formed by abnormal expansion of the outer and media membranes on the intracranial vascular wall caused by congenital growth and development abnormalities and acquired factors. It is also the major cause of subarachnoid hemorrhage (SAH) [Craniotomy aneurysm clipping is one of the main methods for the treatment of IA. The key to anesthesia in this surgery is intended to maintain the stability of intraoperative hemodynamics, ensure the stability of the transmural pressure on both sides of the aneurysm (approximately the difference between mean arterial pressure and intracranial pressure), and prevent aneurysm rupture [Transcutaneous electrical acupoint stimulation (TEAS) is a noninvasive and nonpharmacological treatment method based on the meridian theory of traditional Chinese medicine in China and combined with Western transcutaneous electrical nerve stimulation (TENS). Compared with traditional acupuncture techniques, TEAS positioning is simple, requiring only attachment of the gel electrode sheet to the corresponding acupuncture point; low-frequency pulse current is conducted to the acupuncture point through the gel electrode sheet to stimulate the acupuncture point and achieve the purpose of treating diseases and improving prognosis [With the development of comfort medical care, TEAS is widely used in the clinic. However, the application of TEAS in craniotomy aneurysm clipping is limited. In this study, we aimed to evaluate the effect of applying TEAS on the required intraoperative dosage of remifentanil in patients undergoing selective craniotomy aneurysm clipping, observe whether TEAS can reduce the intraoperative OS, and provide a theoretical basis for the application of TEAS in craniotomy aneurysm clipping.
