漱口提高口腔表面麻醉效果探讨

Improvement of Oral Cavity Topical Anesthesia by Gargle

目的探讨唾液分泌对口腔表面麻醉效果的影响。方法将行口腔表面麻醉的200例病人随机分为观察组和对照组各100例,观察组麻醉前用凉开水漱口,对照组免漱口。比较两组口腔表面麻醉效果及pH值变化。结果两组口腔表面麻醉效果比较,观察组优于对照组,差异有显著性意义(P<0.01);观察组漱口后唾液pH值升高。结论漱口可改变口腔酸碱环境及唾液量,有利于局部麻醉药的浸润和吸收,从而提高局麻效果。

Objective To evaluate the effect of oral cavity topical anesthesia after gargle. Methods Oral cavity topicalanesthesia was performed in 200 cases. Observation group, 100 cases, was anesthetized after gargle and controlgroup, 100 cases, was anesthetized without gargle. The effect of oral cavity topical anesthesia saliva secretion,and change in pH were compared between the tow groups. Results The effectiveness of oral cavity topical anesthe-sia in observation group was more satisfactory than in control group (P<0.01). The changes in pH of saliva inobservation group were superior to those in control group. Conclusion Gargle can improve quantity and quality ofsaliva, facilitate the infiltration and absorb of anesthetics, and enhance the local effect.
