阿替卡因肾上腺素注射液浸润麻醉用于老年人上颌第一磨牙急性牙髓炎的麻醉效果观察

Anesthetic effects of articaine for pulpal anesthesia by using infiltration techniques in the elderly patients with acute pulpitis of maxillary first molar

目的评价阿替卡因肾上腺素注射液(必兰麻)不同麻醉方式用于老年病人上颌第一磨牙急性牙髓炎开髓的麻醉效果。方法 186例上颌第一磨牙急性牙髓炎的老年病人,随机分为2组,对照组采用必兰麻行近颊根浸润麻醉及上牙槽后神经阻滞麻醉;试验组采用必兰麻仅行颊侧局部黏膜下浸润麻醉,注射5 min后常规开髓,清理髓腔,利用100 mm直观模拟标度尺(VAS)及问卷调查获得2组病人开髓时的痛觉数据。结果试验组与对照组的疼痛感觉差异没有统计学意义(P>0.05),开髓及清理髓腔过程中的疼痛均可接受。结论上颌第一磨牙急性牙髓炎仅用必兰麻行颊侧局部黏膜下浸润麻醉可顺利开髓及清理髓腔,无须常规上牙槽后神经阻滞麻醉。

Objective To evaluate the effect of articaine in buccal submocucal infiltration anesthesia of maxillary first molar presenting with acute pulpitis,and to discuss whether it is necessary to deliver posterior superior alveolar nerve block anesthesia.Methods 186 elderly patients with acute pulpitis of maxillary first molar were randomly divided into 2 groups in the study.Test group received buccal infiltration anesthesia,and control group received mesial buccal infiltration anesthesia and posterior superior alveolar nerve block anesthesia.The operation started 5 minutes after injection.All patients were then tested by 100 mm visual analogue scale（VAS） and questionaires to evaluate anesthesia effect.Results No significant difference in VAS score was observed between two groups（P0.05）.The pain during the operation was tolerable in both groups.Conclusions Articaine buccal infiltration anesthesia is highly remmended due to its efficiency,refraining from block anesthesia complications and time saving.
