Transcutaneous Electrical Acupoint Stimulation on Postoperative Dizziness in Hemifacial Spasm Patients

Peking University People's Hospital86 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

The incidence of dizziness at 2 hours after returning to the ward on the day of surgery

The patients and their families will be asked to record a diary about their symptoms of dizziness, nausea, vomiting and headache after surgery, and they will be followed up after surgery.

Time frame: 2 hours after returning to the ward on the day of surgery

Secondary Outcomes

Numerical rating scale (NRS) score of postoperative dizziness

A 0-10 point numerical rating scale (NRS) will be used for evaluation of the severity of postoperative dizziness. 0 means no dizziness, and 10 means very severe dizziness. The degree of dizziness worsens as the number increases.

Time frame: In PACU after extubation, and 2 hours, 6 hours, 24 hours, 48 hours, 72 hours after returning to the ward.

The incidence and severity of postoperative nausea

Nausea severity will be evaluated by a 0-10 point numerical rating scale (NRS). 0 means no nausea, and 10 means very severe nausea. The degree of nausea worsens as the number increases.

Time frame: In PACU after extubation, and 2 hours, 6 hours, 24 hours, 48 hours, 72 hours after returning to the ward.

The number of vomiting after surgery

Vomiting times after surgery.

Time frame: In PACU after extubation, and 2 hours, 6 hours, 24 hours, 48 hours, 72 hours after returning to the ward.

The use of remedial drugs after surgery

Drug used for anti-emetic or anti-dizziness after surgery.

Time frame: From the day of surgery to 72 hours after surgery.

The incidence and severity of postoperative headache

Headache severity will be evaluated by a 0-10 point numerical rating scale (NRS). 0 means no headache, and 10 means very severe headache. The degree of headache worsens as the number increases.
