改良Gow-Gates下牙槽神经阻滞麻醉在下颌阻生第三磨牙拔除术中的应用

Clinical study of modified Gow-Gates technique of inferior alveolar nerve block in impacted mandibular third molar extraction

目的:探讨一种微创高效的下牙槽神经阻滞麻醉方法。方法:将206例门诊拔除下颌阻生第三磨牙患者随机分为2组,实验组105例采用改良Gow-Gates法,对照组101例采用传统口内注射法(Halstead法)。记录麻醉成功率、麻醉效果和并发症,采用SPSS17.0软件包对数据进行统计学分析。结果:改良Gow-Gates法麻醉成功率为97.15%,Halstead法为89.10%,2组间显著差异(P=0.038)。改良Gow-Gates法在麻醉效果A、B级比率为90.48%,Halstead法为87.13%,2组间无显著性差异(P=0.446)。改良Gow-Gates法的并发症显著少于Halstead法(P=0.014)。结论:GowGates下牙槽神经阻滞麻醉是一种微创高效的麻醉方法 。

PURPOSE： To introduce a minimally invasive and more effective teehnique of inferior alveolar nerve bloek. METHODS： Two hundred and six patients who needed extraction of the impacted mandibular third molar were divided randomly into 2 groups： the experimental group （105 cases ） with modified Gow-Gates technique （modified Gow-Gates group） and the eontrol group （101 eases） with Halstead technique （Halstead group）. The anesthetic success rates, effects and eomplieations were recorded and analyzed with SPSS17.0 software package. RESULTS： The anesthetic success rate was 97.15% in modified Cow-Gates group and 89.10% in Halstead group with significant difference between the 2 groups （P=0.038〈0.05）; In comparing the anesthesia grade, the ration of grade A and B accounted for 90.48% in modified Cow- Gates group and 87.13% in Halstead group （P=0.446〉0,05）. Modified Gow-Gates group had much fewer of eomplieations than Halstead group （P=0.014〈0.05）. CONCLUSIONS： Modified Gow-Gates technique is a minimMly invasive and more effective teehnique for inferior alveolar nerve bloek anesthesia.
