目的:观察不同局麻药在下颌阻生智齿拔除术中的麻醉效果及术后镇痛效果。方法:160例下颌阻生智齿分别应用0.5%左旋布比卡因、0.5%布比卡因、2%利多卡因及4%阿替卡因行下牙槽神经、舌神经、颊神经阻滞麻醉,每组40例,观察麻醉效果。结果:左布比卡因组起效时间(3.64±1.50)min,麻醉维持时间(8.69±0.97)h,布比卡因组起效时间(3.73±1.44)min,麻醉维持时间(8.48±1.21)h,利多卡因组起效时间(4.13±2.15)min,麻醉维持时间(2.59±0.67)h,阿替卡因组起效时间(2.17±1.08)min,麻醉维持时间(3.17±0.59)h,四组病例均能达到良好的麻醉效果,均无麻醉不良反应发生。结论:左布比卡因应用于下颌阻生智齿拔除术安全有效,麻醉持续时间长,术后镇痛效果好。
Objective: To observe the anesthetic effect and analgesic effect of different local anesthetics in mandibular impacted wisdom tooth extraction. Methods: 160 cases of mandibular impacted wisdom teeth were treated with 0.5% levobupivacaine, 0.5% bupivacaine, 2% lidocaine and 4% articaine for alveolar nerve, lingual nerve and buccal nerve block respectively Anesthesia, 40 cases in each group, observe the effect of anesthesia. Results: The onset time of the levobupivacaine group was 3.64 ± 1.50 min, the duration of anesthesia was 8.69 ± 0.97 h, the onset time of bupivacaine group was 3.73 ± 1.44 min, and the duration of anesthesia maintenance was 8.48 ± 1.21 ) h, the onset time of the lidocaine group was (4.13 ± 2.15) min, the duration of anesthesia maintenance (2.59 ± 0.67) h, the duration of onset of anesthesia (3.17 ± 0.59) h, four groups of patients can achieve good anesthetic effect, no adverse reactions to anesthesia occurred. Conclusion: Levobupivacaine is safe and effective in the treatment of mandibular impacted wisdom tooth extraction. It has a long duration of anesthesia and good postoperative analgesic effect.
