左旋布比卡因在下颌阻生智齿拔除术中麻醉效果及术后镇痛作用研究

 目的 观察左旋布比卡因在下颌阻生智齿拔除术中的麻醉效果及术后镇痛作用.方法 选择需拔除双侧下颌阻生智齿34例,采用交叉试验方法,分别使用0.5%左旋布比卡因及2%利多卡因进行下齿槽神经麻醉,观察麻醉药起效时间.采用VAS评分法对两组麻醉效果进行评定,并对术后患者服用镇痛药(芬必得胶囊)情况进行记录.结果 0.5%左旋布比卡因及2%利多卡因麻醉药起效时间分别为(6.59±2.20)min和(4.40±1.43)min,两组差异具有统计学意义(P<0.05);左旋布比卡因组术中VAS评分低于利多卡因组,两组差异具有统计学意义(P<0.05);左旋布比卡因组术后服用镇痛药人数为3人,明显少于利多卡因组16人,差异具有统计学意义(P<0.01).结论 采用左旋布比卡因行下齿槽神经阻滞麻醉拔除下颌阻生智齿,术中麻醉有效,术后镇痛作用较好.

Anesthetic efficacy of levobupivacaine for SUFgical removal of.impacted mandibular third molar and ppstoperative pain control

Objective To compare the anesthetic efficacy of 0.5%levobupivacaine with 2%lidocaine in truncal block of the inferior alveolar nerve during the surgical extraction of impacted lower third molars and postoperative pain control.Methods Thirty-four patients underwent removal of symmetrically positioned lower third molars,in 2 separate appointments,under local anesthesia either with 0.5%levobupivacaine or 2.0%lidocaine,in a double-blind,randomized,and crossover manner.Ibuprofen sustained release capsules ware a...
