目的评价传统下牙槽神经阻滞麻醉(直接麻醉)、Akinosi法麻醉与Gow-Gates法麻醉对下牙槽神经阻滞麻醉效果。方法2007年3月至2008年12月在山西医科大学第一医院口腔颌面外科对需拔除下颌智齿患者420例。分别施行直接麻醉、Akinosi法麻醉或Gow-Gates法麻醉,比较其麻醉成功率和优缺点。结果直接麻醉法A级118例(占84.3%);Gow-Gates法A级136例(占97.1%);Akinosi-Vazirani法A级133例(占95%)。直接麻醉法有23例注射麻药前回抽有血,经改变方向后重新注射;Gow-Gates法与Akinosi-Vazirani法无回抽有血病例。结论Gow-Gates法和Akinosi-Vazirani法均可替代直接麻醉方法。其中Akinosi-Vazirani法尤其适用于张口受限和精神紧张患者。

Clinical application and evaluation of three types of block anesthesia of inferior alveolar nerve

0bjective Evaluating three types of block anesthesia of inferior alveolar nerve. Methods Traditional block anesthesia of inferior alveolar nerve， Gow-Gates anesthesia and Akinosi-Vazirani anesthesia were performed on the patients who needed third molar surgery. Compare the strengths and weaknesses and the success rate of anesthesia. Results Rank A of traditional block anesthesia was 84.3%;rank A of Gow-Gates anesthesia was 97.1%;rank A of Akinosi-Vazirani anesthesia was 95%.Totally 23 cases of traditional block anesthesia had pumpback blood，needing to change direction and reinject.No case of Gow-Gates anesthesia and Akinosi-Vazirani anesthesia had pumpback blood.Conclusion Gow-Gates anesthesia and Akinosi-Vazirani anesthesia could substitute the traditional block anesthesia. Akinosi-Vazirani anesthesia is especially suitable for limitation of mouth opening and psychentonia patient.
