Summary

To observe the prevention and treatment effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative dizziness in patients with hemifacial spasm undergoing microvascular decompression surgery, and its possible mechanisms.

Detailed description

Hemifacial spasm (HFS) is mainly caused by vascular compression on the roots of the VII cranial nerves from the brain stem. Microvascular decompression (MVD) is the exact surgical method for the treatment of HFS, but the incidence of dizziness and postoperative nausea and vomiting (PONV) after MVD is extremely high. Despite the use of dual antiemetic therapy during the operation, the incidence of PONV within 24 hours after MVD is still as high as 66.7%. Medication alone has limited effects on dizziness and PONV treatment after MVD. Meta-analysis shows that transcutaneous electrical acupoint stimulation (TEAS) is associated with the reduction of post-emetic remedies and the incidence of dizziness after general anesthesia, and it can be integrated into the multi-modal therapy of PONV. Therefore, the purpose of our study is to observe the prevention and treatment effect of TEAS on postoperative dizziness in patients with hemifacial spasm undergoing microvascular decompression surgery, and explore its possible mechanisms.
