两种不同下牙槽神经阻滞麻醉方法的评价

Evaluation of two different methods of inferior alveolar nerve block anesthesia

目的 评价对两种下牙槽神经阻滞麻醉方法。方法 对 40例需拔除双侧下颌智齿病人分别施行传统下牙槽神经阻滞麻醉法和Akinosi法麻醉 ,比较其麻醉成功率和优缺点。结果 传统法成功率为 92 5 % ,Akinosi法为 95 % ,两者之间差异无显著性 ;颊神经麻醉不全传统法为 0 ,而Aki nosi法为 15 % ;回抽血阳性传统法为 10 % ,Akinosi法为 0。结论 Akinosi法是一种可替代传统法的麻醉方法 ,尤其适用于张口受限和精神紧张病人。

Objective To evaluate two methods of inferior alveolar nerve block anesthesia. Methods The conventional nerve block technique for administration of local anesthesia was compared with Akinosi mandibular block technique in 40 patients required bilateral extraction of impacted mandibular third molars,including theirs success rate and advantages. Results The success rate of the conventional technique was 925%,Akinosi technique was 95%;In the 15% of patients who received Akinosi injections without onset of buccal nerve anesthesia,conventional technique was 0; blood regurgition in springe of conventional technique was 10%,and Akinosi technique was 0. Conclusion The Akinosi technique is an alternative method of traditional mandibular block technique,and especially valuable in patients with limited mandibular opening and apprehension.
