椎旁神经阻滞可提供术中术后镇痛,且对血流动力学和呼吸影响轻微[1,2]。但传统的盲探穿刺存在较高的失败率和并发症。本文探讨超声引导下连续椎旁神经阻滞在乳腺癌根治术患者的应用效果。资料与方法1.一般资料择期乳腺癌根治术女性患者60例,年龄41-78岁,体重46-82kg。排除有严重心肝肺肾疾患、凝血异常、穿刺部位有感染、手术史及脊椎畸形者。随机均分为全麻复合连续椎旁神经阻滞组(A组),全麻复合硬膜外阻滞组(B组)。本研究 Paravertebral nerve block provides intraoperative and postoperative analgesia with mild effects on hemodynamics and respiration [1,2]. However, traditional blind probing has higher failure rates and complications. This article discusses the application of ultrasound-guided continuous paravertebral nerve block in patients with radical mastectomy. Materials and Methods 1. General Information Elective radical mastectomy in 60 patients with female patients, aged 41-78 years old, weighing 46-82kg. Excluding severe liver, liver and kidney disease, abnormal blood coagulation, puncture site infection, history of surgery and spine deformity. Randomly divided into general anesthesia combined with paravertebral nerve block group (A group), general anesthesia combined with epidural block group (B group). this research
