STA无痛麻醉仪韧带内注射麻醉在急性牙髓炎患者中的应用效果

Application effects of intraligament injection of STA painless anesthesia instrument anesthesia in patients with acute pulpitis

目的:探讨STA无痛麻醉仪韧带内注射麻醉在急性牙髓炎(AP)患者中的应用效果。方法:选取2020年1月至2022年1月该院收治的80例AP患者进行前瞻性研究,按照随机数字表法将其分为对照组和观察组各40例。对照组采取常规卡式注射器注射麻醉,观察组采取STA无痛麻醉仪韧带内注射麻醉,比较两组临床相关指标(疼痛消退时间、炎症消退时间和红肿消退时间)水平、麻醉总有效率、麻醉舒适度(Kuttner面部表情法)评分、操作耐受力(Houpt行为量表)评分和麻醉后不良事件发生率。结果:观察组疼痛消退时间、炎症消退时间和红肿消退时间均短于对照组,差异有统计学意义(P<0.05);观察组麻醉总有效率为97.50%(39/40),高于对照组的80.00%(32/40),差异有统计学意义(P<0.05);观察组Kuttner评分低于对照组,Houpt评分高于对照组,差异均有统计学意义(P<0.05);两组心动过速、恶心等不良事件发生率比较,差异均无统计学意义(P>0.05);观察组大面积颊侧、舌侧软组织麻木发生率为7.50%(3/40),低于对照组的37.50%(15/40),差异有统计学意义(P<0.05)。结论:STA无痛麻醉仪韧带内注射麻醉应用于AP患者可提高麻醉总有效率和Houpt评分,降低临床相关指标水平、Kuttner评分和不良事件发生率,效果优于常规卡式注射器注射麻醉。

Objective:To investigate application effects of intraligament injection of STA painless anesthesia instrument anesthesia in patients with acute pulpitis(AP).Methods:A prospective study was conducted on 80 AP patients admitted to this hospital from January 2020 to January 2022.They were divided into control group and observation group according to the random number table method,40 cases in each.The control group was anesthetized by conventional cartridge syringe injection,while the observation group was anesthetized by intraligament injection of STA painless anesthesia instrument.The levels of clinical related indicators(pain regression time,inflammation regression time and swelling regression time),the total effective rate of anesthesia,the anesthesia comfort(Kuttner facial expression method)score,the operation tolerance(Houpt behavior scale)score,and the incidence of adverse events after anesthesia were compared between the two groups.Results:The pain regression time,the inflammation regression time and the swelling regression time in the observation group were shorter than those in the control group,and the differences were statistically significant(P<0.05).The total effective rate of anesthesia in the observation group was 97.50%(39/40),which was higher than 80.00%(32/40)in the control group,and the difference was statistically significant(P<0.05).The Kuttner score of the observation group was lower than that of the control group,the Houpt score was higher than that of the c ontrol group,and the differences were statistically significant(P<0.05).There was no significant difference in the incidence of adverse events such as tachycardia and nausea between the two groups(P>0.05).The incidence of large area buccal and lingual soft tissue numbness in the observation group had lower was 7.50%(3/40),which was than 37.50%(15/40)in the control group,and the difference was statistically significant(P<0.05).Conclusions:Intraligament injection anesthesia of STA painless anesthesia instrument in the AP patients can improve the total effective rate of anesthesia and the Houpt scores and reduce the levels of clinical related indicators,the Kuttner scores and the incidence of adverse reactions.Moreover,it is superior to conventional cartridge syringe injection anesthesia.
