目的探讨计算机控制下的口腔无痛注射仪(Single Tooth Anesthesia,STA)在口腔颌面外科局部浸润麻醉中的无痛效果、护理特点以及应用前景.方法将120例行局部浸润麻醉的拔牙患者随机分为两组,使用STA注射仪注射为实验组,使用传统手动注射器注射为对照组.在注射过程中使用心率监测仪监测两组患者的心率.通过比较两组患者注射后的疼痛视觉模拟评分(VAS)以及注射前、注射中的心率变化来评价注射的疼痛程度.结果两组患者VAS评分结果显示88.3%的实验组患者评价注射为无痛或轻微疼痛,而对照组中80%患者评价为中等以上疼痛.实验组患者注射中的心率较注射前显著性下降(P＜0.05),而对照组患者注射前、注射中心率无统计学差异.结论 STA能降低患者的疼痛,减少患者在拔牙术前的紧张感,从而配合医生的操作,使治疗得以顺利进行.

Objective To explorer the effects of the STATM anesthetic delivery system in oral local infiltration anesthesia , nursing characteristics and its application prospect. Methods One hundred and twenty patients undergoing pre-orthodontic extraction were randomly divided into two groups. The STATM was used in experimental group and in the control group the traditional hand injection was performed. After each injection, patients evaluated pain during needle insertion and injection with visual analog scale. The heart rates of the patients were recorded before and during injection. Results Statistical analysis indicated that the STATM group had a lower VAS value than the control group. During injection, the heart rates of the STATM group decreased significantly compare with the control group ( P ＜ 0. 05 )Conclusions The STATM system can reduce the pain during the needle injection and anesthetic delivery, and decrease the tension before dental extraction.
