目的观察阿替卡因对上颌磨牙牙髓的麻醉效果及不良反应。方法选择148例176颗上颌磨牙牙髓炎的患者,随机分为A、B两组,每组各74例。A组采用阿替卡因肾上腺素注射液(必兰)颊侧及腭侧粘膜下浸润,剂量1.7ml。B组采用2%的盐酸利多卡因传统阻滞麻醉,剂量5ml。通过0～10数字疼痛强度量表(numerical rating scale,SNK)法对注射和操作开髓,拔髓的疼痛程度进行评分,对比其麻醉效果。结果 A、B组注射疼痛评分分别为1.96±2.14、5.34±1.90,有统计学差异(P<0.05),而两组操作疼痛评分为0.96±2.25、1.24±2.74,无统计学差异(P>0.05)。结论阿替卡因对上颌磨牙的浸润麻醉与传统的阻滞麻醉在操作疼痛评分差异无显著性,但注射疼痛明显低于阻滞麻醉。说明阿替卡因在治疗上颌磨牙患者中麻醉效果显著,并且减小了患者注射时的痛苦,缓解了患者的紧张心态。
Objective To observe the anesthetic effects and side effects of articaine on maxillary molar dental pulp. Methods A total of 176 patients with 176 maxillary molars with pulpitis were selected and randomly divided into A and B groups, 74 in each group. In group A, buccal and palatal submucosal infiltration of articaine adrenaline injection (Bilan) was used in a dose of 1.7 ml. Group B with 2% lidocaine hydrochloride conventional block anesthesia, the dose of 5ml. The 0 ~ 10 numerical rating scale (SNK) method was used to evaluate the pain degree of the pulp and the pulp during injection and operation, and the anesthetic effects were compared. Results The scores of pain in group A and group B were 1.96 ± 2.14 and 5.34 ± 1.90, respectively (P <0.05), while the pain scores of two groups were 0.96 ± 2.25 and 1.24 ± 2.74, with no statistical difference (P> 0.05). Conclusion Articain has no significant difference in the operative pain score between the maxillary molars and the traditional block anesthesia, but the injection pain is significantly lower than that of the block anesthesia. Indicating the significant effect of articaine in the treatment of maxillary molar patients with narcotic effect, and reduce the pain of patients when injected, relieve the patient’s nervous attitude.
