目的:观察STA无痛麻醉仪在急性牙髓炎治疗中的疗效。方法:选择2013年6月—2014年7月来我科就诊患者82例,随机分为观察组和对照组,每组41例。观察组采用STA无痛麻醉仪韧带内注射麻醉下确认治疗,对照组采用常规卡式注射器抽取相同麻醉药物手持推注局部浸润或阻滞麻醉确认治疗。记录确诊、麻醉起效、失效时间及麻药用量并患者自行评估疼痛程度。结果:观察组确诊,麻醉药物起效及失效时间,麻醉药物用量观察组明显少于对照组(P<0.05);麻醉药物注射过程中观察组疼痛明显轻于对照组(P<0.05);上颌磨牙在口腔治疗中镇痛有效率观察组与对照组无明显差异(P>0.05);下颌磨牙在口腔治疗中镇痛有效率观察组与对照组存在显著差异(P<0.05)。结论:STA无痛麻醉仪韧带内注射在急性牙髓炎治疗中有较好的临床应用价值。特别对于缓解诊疗过程中的疼痛,增加患者就诊舒适感,降低恐惧心理,使服务更加人性化,由此提高了患者治疗的依从性。
Objective: To observe the efficacy of STA painless anesthesia in the treatment of acute pulpitis. Methods: 82 patients admitted to our department from June 2013 to July 2014 were randomly divided into observation group and control group, with 41 cases in each group. The observation group was treated with intranasal anesthesia with STA painless anesthesia instrument, while the control group was treated with conventional card-type syringe with the same anesthetic drug as the local infiltration or block anesthesia. Record diagnosis, onset of anesthesia, expiration time and amount of anesthetic and patient self-assessment of the degree of pain. Results: In the observation group, the onset and failure time of anesthetic drugs were significantly lower than those in the control group (P <0.05). The pain in the observation group was significantly lighter than that in the control group during anesthesia injection (P <0.05) There was no significant difference between the observation group and the control group (P> 0.05). The effective rate of analgesia during the oral treatment of mandibular molar was significantly different between the observation group and the control group (P <0.05). Conclusion: STA painless anesthesia intra-ligament injection in the treatment of acute pulpitis has a better clinical value. Especially for alleviating the pain in the process of diagnosis and treatment, increasing patient comfort, reducing fear, making the service more humane, thereby improving patient compliance with treatment.
