老年人口腔局麻注射进针点涂抹利多卡因凝胶的研究

目的探讨口腔局麻注射进针点涂抹利多卡因凝胶对老年人的影响。方法将84例需要口腔局麻注射的老年患者随机分为两组，每组各42例，实验组在注射进针点涂抹利多卡因凝胶黏膜麻醉后再注射麻醉，对照组直接注射麻醉，分别对注射进针时疼痛程度及麻醉注射前后血压、心率的变化进行比较。结果两组注射进针时疼痛差异有统计学意义（P〈0．05），麻醉后血压变化差异有统计学意义（P〈0．05），心率变化差异无统计学意义（P〉0．05）。结论口腔局麻注射进针点涂抹利多卡因凝胶能减轻注射进针时的刺痛，有助于消除老年人对麻醉注射产生的恐惧心理，预防治疗中血压的升高，是一种经济实用、简单方便的口腔局麻方法。

Research on oral local anesthesia injection into the pin-point applied with lidocaine gel to the elderly

Objective To explore the effect of oral local anesthesia injection into the pin-point applied with lidocaine gel to the elderly. Methods 84 cases of the elderly patients which need to receive the oral local anesthesia injection were randomly divided into two groups, each has 42 cases. The experimental group was applied with lidocaine gel on the surface of the pin-point before the oral local anesthesia injection, the control group was injected with local anesthesia directly. The pain level when the elderly was being injected, the change of blood pressure and heart rate before and after the oral local anesthesia injection were compared. Results Between the two groups, Significant differences were found in the pain level and the change of pressure before and after the anesthesia (P< 0.05), while no significant difference was found in heart rate before and after the anesthesia. Conclusions Oral local anesthesia injection into the pin-point applied with lidocaine gel can reduce the injection pain, eliminate the elderly fear and prevent the blood pressure from rising. It is an economic, practical, and convenient method of oral local anesthesia.
