[Application of transcutaneous electric nerve stimulation in operation of thyroid tumors]
1Department of Anesthesia, Luohe Central Hospital, Henan 462000, China.
Objective:
To study the effect of transcutaneous electric nerve stimulation for decreasing stress response and strengthening the anesthetic effect in the operation of thyroid tumors.
Methods:
Sixty patients with thyroid tumors were randomly divided into an observation group and a control group, 30 cases in each group. All of them were given modified one-point cervical plexus nerve obstruction. The stimulation at bilateral Hegu (LI 4) and Quchi (LI 11) with HANS was added to the observation group from the beginning to end of operation.
Results:
The blood pressure, heart rate and jerking reflection were decreased significantly as compared with the control group. The oxygen saturation and respiratory frequency did not change.
Conclusion:
Cardiovascular stress response can be decreased with HANS in the operation of thyroid tumors and anesthetic effect can be strengthened.
