1、连续外周神经阻滞麻醉与镇痛,山东中医药大学附属医院麻醉科 王连主,为何要行连续神经阻滞,手术 长时间手术如：血管神经吻合、断指再植，即能满足长时间需要又能扩张血管对术中及术后病情都有利。,术后镇痛（PCNA） 对血流动力学影响小，无需严密监测，减少恶心、呕吐、皮肤瘙痒、尿潴留，以及对凝血机制异常病人的担忧。 外周神经阻滞可有效阻止疼痛刺激的传入，防止中枢敏化。 对运动疼痛效果好，早期下床锻炼。 可行走，可带回家。,疼痛治疗 骨折的术前疼痛、神经病理性疼痛、癌性疼痛等,连续神经阻滞用药,手术麻醉： 成人：0.5罗哌卡因 初始剂量：0.5ml/kg 最大量30ml 小儿： 0.375罗哌卡因 初始
2、剂量： 0.5ml/kg 最大量20ml,连续神经阻滞用药,术后镇痛与疼痛治疗： 成人：0.2罗哌卡因 小儿：0. 125罗哌卡因 PCNA：负荷剂量：5ml 输注速率：2ml/h 单次剂量：0.5ml 锁定时间：15min,主要内容,连续肌间沟臂丛神经阻滞 连续股神经阻滞 连续髂筋膜间隙阻滞,一、连续肌间沟臂丛神经阻滞,臂丛神经解剖分布,C5腋神经三角肌肩外展 C6肌皮神经肱二头肌肘屈曲 C7桡神经伸肌群肩肘腕伸 C8 正中神经屈肌群腕指屈 T1 尺神经手内肌拇对掌小指屈,腋N,上臂内侧皮N和肋间臂,前臂内侧皮N,桡N,尺N,前臂外侧皮N(肌皮N),正中N,连续肌间沟臂丛神经阻滞应用,上肢桡
