【摘要】 目的探讨在甲状腺手术中或者在麻醉效果不好时,将麻醉药准确地注射到颈丛神经和颈神经袢位置,对术中麻醉效果的影响。方法随机选取甲状腺手术前实施了颈丛神经阻滞麻醉但麻醉效果欠佳的患者60例,于手术中经手术切口区域分别采用0.5%罗哌卡因、1%利多卡因和1.3%利多卡因做二次颈丛神经阻滞麻醉,同时随机选取采用颈丛神经阻滞麻醉效果不佳行术中补充局麻的患者20例作为对照组。结果各组经手术区补充行颈丛神经阻滞麻醉的方法均较采用局部浸润麻醉方法效果好,疼痛明显减轻。结论甲状腺手术中经手术切口作二次颈丛神经阻滞麻醉对术前颈丛麻醉效果不佳的患者有良好的临床效果。更多还原

【Abstract】 Objective To explore the clinical efficacy of a second cervical plexus nerve block anesthesia in thyroidectomy or in case of poor response to preoperative anesthesia.Methods Sixty patients were randomly selected who had received cervical plexus nerve block but with poor response before surgery.They were given 0.5% ropivacaine,1% lidocaine and1.3% lidocaine through the incision area for a second cervical plexus block.Twenty patients who showed poor response to the cervical plexus nerve block and received an additional local anesthesia were selected as the control group.Results Groups with a second cervical plexus block showed better effects than the control group,with obvious pain relieving(P<0.01).Conclusions It shows better clinical efficacy to give cervical plexus nerve block again through the incision area in case of poor response to preoperative anesthesia in hyreoidectomy.更多还原
