Clinical observation on effect of auricular point injection combined with superficial anesthesia for nasal endoscopy surgery / 中国针灸

ABSTRACT

<p><b>OBJECTIVE</b>To observe the anesthetic effect of combined superficial anesthesia and auricular point injection for nasal endoscopy surgery.</p><p><b>METHODS</b>Forty cases of grade I - II as ASA for nasal endoscopy surgery were randomly divided into a combined auricular point injection and superficial anesthesia group (group A) and a simple superficial anesthesia group (group B), 20 cases in each group. Both groups accepted superficial anesthesia 2 times on the bilateral nasal cavities with cotton pieces that was immersed in the mixed solution of 1% Tetracaine 30 mL and 0.1% Adrenaline 2 mL. In group A, bilateral auricular points of Shenmen and Waibi (externol nose) were injected with 0.1 mL Vitamin B1 solution before the superficial anesthesia. After 10 min of observation, surgery was carried out. During the surgery, the patients only accepted a small amount of vasoactive substance and Fentanyl according to the changes of patient's blood pressure, heart rate and pain feeling.</p><p><b>RESULTS</b>The total effective rate of 90.0% in the group A was significantly better than 75.0% in the group B (P<0.05). The rate of using analgetic and vasoactive substance in the group A was obviously less than that of the group B.</p><p><b>CONCLUSION</b>Combined auricular point injection and superficial anesthesia has good anesthetic effect for nasal endoscopy surgery.</p>
