7、精神紧张、焦虑的情绪，应加强心理护理，及时与患者沟通。,4.Rest and activity：绝对卧床休息，避免过多活动及剧烈咳嗽。,护理措施（Nursing measures）,5.Medication nursing：遵医嘱应用减慢心率，控制血压的药物时，应密切观察生命体征、尿量等情况，注意观察药物的效果和不良反应。硝普钠属血管平滑肌松弛剂，注意避光，现用现配，超过6h应重新配制。,护理措施（Nursing measures）,6.Diet：以清淡、易消化、富含维生素的流质或半流质食物为宜；做好口腔护理，鼓励患者多饮水，进食新鲜水果、蔬菜和低盐低脂的食物。7.Excretion：保持大便

8、通畅，减少便秘，必要时给予通便药物，防止排便时血压骤升，导致夹层破裂。,护理措施（Nursing measures）,8.Skin care：定时协助翻身，动作应轻柔。可铺防褥疮气垫床，用软垫保护受压部位，预防压疮发生。9.保证抢救药品及物品处于功能位，发生病情变化时及时报告医生，给予对症处理。,健康教育（Health education）,戒烟戒酒低盐低脂饮食,坚持服药控制血压自测脉搏,调整心态心情舒畅避免激动,门诊复查不适随诊,避免复发延长生命,按时休息劳逸结合循序渐进,主动脉夹层的概述和发病率,发病机制、易患因素及分型,治疗及院前急救,临床表现及辅助检查,回顾（Review ）,护理措施
