【摘要】：目的:比较等剂量不同浓度的左旋布比卡因对超声引导下肋间神经阻滞的效果。方法:择期行单侧乳房肿块切除术患者90例,随机分为3组,在超声引导下行2~5肋肋间神经阻滞麻醉,3组使用等剂量不同浓度的局麻药,分别为0.25%左旋布比卡因24 m L(A组),0.375%左旋布比卡因16 m L(B组),0.5%左旋布比卡因12 m L(C组)。观察3组患者麻醉起效时间、麻醉完善时间、手术开始切皮时疼痛视觉模拟评分、手术中牵拉深部组织时疼痛视觉模拟评分、镇痛维持时间以及麻醉镇痛不全发生率和局麻药中毒发生率。结果:3组患者麻醉起效、麻醉完善时间随左旋布比卡因浓度上升而缩短,镇痛维持时间延长(P0.05~P0.01)。结论:等剂量左旋布比卡因用于超声引导下肋间神经阻滞时,适当提高浓度可缩短麻醉起效时间及完善时间,延长麻醉镇痛维持时间。
[Abstract]:Objective: to compare the effects of different doses of levobupivacaine on intercostal nerve block guided by ultrasound. Methods: 90 patients with unilateral breast mass resection were randomly divided into 3 groups. Group 3 of intercostal nerve block anesthesia under ultrasound guidance was treated with local anesthetics of the same dose and different concentration. 0.25% levobupivacaine 24 mL / L group A was 0.375% levobupivacaine 16 mL / L group B and 0.5% levobupivacaine 12 mL / L group C respectively. The onset time of anaesthesia, the time of improvement of anesthesia, and the visual analogue score of pain at the beginning of operation were observed in three groups. The visual analogue score of pain, the duration of analgesia, the incidence of incomplete analgesics and the incidence of local anaesthetic poisoning were observed during the operation. Results the anesthesia was effective in the three groups. The anesthetic consummation time was shortened with the increase of the concentration of levobupivacaine, and the maintenance time of analgesia was prolonged. Conclusion: the same dose of levobupivacaine can be used in ultrasound guided intercostal nerve block. Increasing the concentration can shorten the effective time and perfect time and prolong the maintenance time of anesthesia analgesia.
