摘要
【目的】对TMY-1无痛口腔局麻注射仪在拔牙患者术前局部麻醉时的恐惧程度、疼痛程度及麻醉效果进行临床评价。【方法】将134例门诊拔牙患者随机分成两组(每组67例),试验组采用无痛口腔局麻仪+复方阿替卡因进行麻醉,对照组采用复方阿替卡因传统的手推卡局式注射麻醉,对注射中患者的恐惧感及配合度进行比较,注射后利用10 cm视觉模拟评分法(VAS)由患者对注射时的疼痛感进行评分及归类,医生于拔牙术后评定不同麻醉方式的麻醉效果。【结果】试验组研究对象在注射时的恐惧程度低于对照组,存在统计学差异(χ2=29.17,P<0.05),试验组研究对象在注射时的疼痛程度低于对照组,存在统计学差异(χ2=49.83,P<0.05),两种方式的局部麻醉效果总体上并无统计学差异(χ2=1.20,P>0.05)。【结论】采用无痛口腔局部麻醉仪能够有效改善患者对于拔牙术前局部麻醉的恐惧感及焦虑情绪,并减轻注射麻药时患者的疼痛反应,麻醉效果良好,尤其适合应用于牙科焦虑症较严重,情绪敏感的患者。
【Objective】To evaluate the effect of TMY-1 painless oral local anesthetic instrument for local anesthesia during preoperative injection of local anesthesid.【Methods】 A totac of 134 patients were divided to two groups（67 for each group）,In experimental group injecting anesthesia by painless oral local anesthesia instrument ＋ compound articaine,and in control group,injecting anesthesia with compound articaine by traditional hand-push cartridge.and then compare patients＇ degree of fear and degree of obedience in injection,were compared graded and classified by 10 cm visual analogue scales（VAS）.【Results】 The level of fear and pain during injection in the experimental group was lower than the control group,the result showed a statistical difference（χ2=29.17,P0.05） in degree of fear and a statistical difference（χ2=49.83,P0.05） in degree of pain,and no substantially statistical difference（χ2=1.20,P0.05） showed in effects of both anesthesia methods.【Conclusions】 Painless oral local anesthesia instrument is useful to reduce patients＇ fear and anxiety to local anesthesia before tooth extraction surgery,abate patients＇ pain reaction to anesthesia injection.Anesthesia effect is favorable,especially for patients in serious dental anxiety or sensitive emotion.
