style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　低血压是指动脉收缩压低于90毫米汞柱，舒张压低于60毫米汞柱。成人正常血压低于90/60毫米汞柱，老年人低于100/70毫米汞柱，称为低血压。&nbsp;</span><br/><span style=\"color:#ffffff\">中国论文网 http://www.xzbu.com/6/view-4549546.htm</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　引起低血压的原因很多，令人感到困惑的是有一部分老年人吃饭后会发生低血压。所谓“餐后低血压”，是指进餐后2小时以内血压下降水平超过20毫米汞柱；或餐前收缩压超过100毫米汞柱，而餐后收缩压小于90毫米汞柱。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　对餐后低血压的诊断一般通过测定餐前血压和餐后2小时内血压（每15～30分钟测1次，以最低血压值作为餐后血压）来确诊。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　餐后低血压是老年人的常见疾病，比体位性低血压更常见，多见于心血管疾病、高血压病、截瘫、糖尿病、帕金森病、多系统器官功能衰退以及生活不能自理的老年人，也可见于健康老人。其临床表现因不同人群而有所不同：健康老年人先出现症状，然后测到血压降低；自主神经功能障碍的患者，只有血压下降较大幅度时才出现症状；高血压患者一般血压下降即出现临床表现。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　引起餐后低血压的原因主要是由于餐后内脏血流量增加及老年人压力反射反应的迟钝。研究表明，人在进餐后迷走神经兴奋，胃、肠、胰腺等组织通过自分泌、旁分泌而产生一些具有扩血管作用的体液因子，导致门静脉、肠系膜血管明显扩张，内脏血流量增加。大量的血液流入胃肠道，回心血量减少，当心率和外周血管阻力未相应增加时，就会导致餐后低血压。对于年轻人来讲，其血压调节能力强，餐后血压下降的幅度小，一般不会出现什么不适的症状。对于老年人来说，由于压力感受器易发生动脉粥样硬化，其敏感性降低，对餐后血压下降不能迅速作出反应。老年人尤其是自主神经功能损害者还存在交感神经功能代偿不全，心率加快和血管收缩不明显，对餐后血压下降不能进行有效代偿而发生一系列的低血压症状。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　针对性的防范措施&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　1饮食疗法 低碳水化物饮食，少量多餐，因为高碳水化物尤其是葡萄糖容易诱发餐后低血压。在医生指导下，可适当增加钠盐和水分的摄入，保证充足的血容量。避免在进餐时饮酒，避免在血液透析时进食。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　2适量运动 餐后适当散步可通过增加心率和心排血量来维持正常血压，达到治疗餐后低血压的目的，但要避免过量运动。餐后若出现低血压症状，应采取平卧位。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　3治疗基础疾病 虽然降压药有可能诱发餐后低血压，但有效控制高血压反而能改善餐后低血压。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　高血压患者服用利尿剂时餐后血压下降水平明显高于非利尿剂，对于此类患者应选用非利尿剂降压药；&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　若确定是降压药诱发餐后低血压者，则应在两餐之间服用降压药；&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　冠心病患者应用硝酸酯类，或心力衰竭时用利尿剂可能加重餐后低血压，如无绝对指征不宜用此类药物；&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　帕金森病患者餐后血压下降明显，与抗帕金森病药物本身具有降压作用有关；&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255,

#ffffff;\">　　餐后低血压主要发生于早餐（65%），而中餐（19%）、晚餐（16%）亦可发生。多数餐后低血压患者无症状，少数可表现为餐后心绞痛、头昏、晕厥、黑矇、乏力、吐词不清、跌倒、一过性脑缺血等心脑缺血症状,多发生在危险人群中。</span><br /><span style=\"font-family: Arial, 宋体; font-size: 14px;

background-color: #ffffff;\">　　一般来说，可以通过改变一些生活习惯来达到。具体表现为：饮食不宜过热，温度在40℃～45℃为宜;要注意混合饮食，不要单纯食用以淀粉或葡萄糖为主的食物作为早餐;餐后在沙发或椅子上多坐一会儿，5～10分钟后再起立活动;已发生过餐后低血压症状的老年人，进早餐前可先喝一小杯凉开水。除此之外，还有一些其他的注意事项，比如不要长久站立、劳累，不要突然改变体位，不要餐后立即洗澡，更不要长时间浸泡在热水里。</span><br /><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color:

href=\"http://www.haodf.com/jibing/dongmaizhouyangyinghua.htm\" target=\"_blank\" style=\"margin: 0px; padding: 0px; text-decoration: none; color: rgb(51, 51, 51); outline:

26.6667px; white-space: normal; background-color: rgb(255, 255, 255);\">在这里讲一个道理，血压有什么作用呢？血压是推动血液向远端流动的压力，压力大推动力大，血液的流量就多，流的距离就远，组织的供血量就多，脏器的功能就能正常。反之。压力小推动力就小，血流量就少，血液流动的距离就近，组织的供血就会减少，脏器的功能就会不正常。但血压过高会对血管壁产生压力，严重时会发生扩张，轻则造成慢性血管损伤，重则发生破裂出血。因此，血压过高血流量是增加了，但血管受损伤了，过高还有可能造成血管破裂，这也是不值得的；反之，血压低，供血减少，脏器功能障碍同样也要避免。</p><p

font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　对于老年人来说，体位性低血压的危害在于该病可引起跌倒、晕厥、心肌梗死和脑血管病等意外事件的发生。那么，老年人在日常生活中应如何避免发生体位性低血压呢？&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　1.要少吃多餐，每餐不宜吃得过饱，餐后不要立即活动，可在休息几分钟后再起身。同时要多饮水，每日的饮水量要达到2～3升。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　2.在洗热水浴时要事先准备好浴垫或椅子。洗浴时应坐在浴垫或椅子上。洗完后可适当地躺一会儿或静坐一会再起身活动。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　3.在长时间站立时，应每隔几分钟就活动一下身体。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　4.在睡觉时应使用高25～30厘米的枕头。起床时要尽量减慢变换体位的速度，最好能分段改变体位，即先由卧位转为坐位，静坐几分钟后，再起身活动。另外，老年人在弯腰后不要突然直起上身，起身时最好能用手扶墙或其他物体，以防止发生体位性低血压。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　5.要坚持进行体育运动，但每次的运动量不宜过大，也不要做体位变化过快的运动。比较适合老年人的运动有步行、慢跑和游泳等。运动的强度应以运动后无气喘，心率不超过每分钟110次为宜。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　6.在服药前要仔细阅读药品说明书，慎用能引起头晕和低血压的药物。若必须使用这些药物时，应密切观察用药后的反应，若出现头晕、头痛或视力改变等症状时，应立即停药，必要时可去医院诊治。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　7.要合理调整饮食，晚饭最好不要喝粥或喝汤，以免因为起夜次数增多而发生体位性低血压。另外，国外临床研究发现，使用咖啡因防治体位性低血压的效果不错。因此，老年人（高血压患者除外）可在每天早餐前服用0.25克的咖啡因或喝一杯浓咖啡，以预防饭后体位性低血压的发生。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　8.患有能引起体位性低血压疾病的老年人应积极治疗这些疾病。&nbsp;</span><br/><span style=\"font-family: Arial, 宋体; font-size: 14px; line-height: 25.2px; background-color: rgb(255, 255, 255);\">　　另外，当老年人发生了体位性低血压出现头晕甚至晕厥时，家属应立即让其平卧（可取头低脚高的姿势），并解开其领口的衣扣，按摩其四肢的肌肉，注意观察其脉搏的变化。一般情况下，此类患者在数分钟后就可恢复正常。若患者的病情不见好转，应及时送其去医院诊治。</span></p>","barId":"2012","topicTypeId":"3","topicThemeId":"1035","readLevel":0,"files":"","clickNoLikeCount":0,"clickLikeCount":0,"clickCount":1571,"score":0,"partCount":0,"replayCount":0,"publishStatus":1,"publishTime":1486356642185,"isCream":0,"canReply":0,"shareUrl":null,"foodCouponVal":1,"emailNotice":0,"permission":0,"zlyShare":0,"status":0,"sort":0,"highlight":0,"highlightEffectTime":0,"digest":0,"digestEffectTime":0,"top":0,"topEffectTime":0,"closed":0,"stamp":0,"icon":0,"bgcolor":null,"fontcolor":null,"favtimes":0,"isAdopt":0,"adoptId":null,"sortDate":1486356642183,"metaSearch":null,"rn":null},"userAllInfo":{"id":null,"isDel":0,"createAt":0,"createBy":null,"createName":null,"updateAt":0,"updateBy":null,"updateName":null,"username":null,"password":null,"level":0,"nickName":null,"realName":null,"signName":null,"head":null,"phone":null,"mobile":null,"wechat":null,"qq":null,"email":null,"address":null,"identityType":0,"userType":0,"isPhoneBind":0,"status":0,"accountSource":0,"isStrangerMsg":0,"departmentId":null,"departmentName":null,"sex":0,"provinceId":null,"cityId":null,"userLevel":0,"modifyNameCount":0,"forumUser":{"id":"6aad1b12ea7211e6a61c00163e04584d","isDel":0,"createAt":1486168781822,"createBy":"b1a5ca4ddfad11e6a61c00163e04584d","createName":"小海螺","updateAt":0,"updateBy":null,"updateName":null,"username":"茉莉花","password":"888888","level":0,"nickName":"茉莉花","realName":null,"signName":"随遇而安","head":"http://01luntan.com/ly_img/1486169681471.jpg","phone":null,"mobile":null,"wechat":null,"qq":null,"email":null,"address":null,"identityType":1,"userType":2,"isPhoneBind":0,"status":0,"accountSource":0,"isStrangerMsg":0,"departmentId":null,"departmentName":null,"sex":2,"provinceId":"140000","cityId":"140500","userLevel":0,"modifyNameCount":1},"forumUserActiveInfo":{"id":"6ab0cc6bea7211e6a61c00163e04584d","isDel":0,"createAt":0,"createBy":null,"createName":null,"updateAt":1707962474321,"updateBy":"6aad1b12ea7211e6a61c00163e04584d","updateName":"茉莉花","userId":"6aad1b12ea7211e6a61c00163e04584d","topicCount":551,"replayCount":73,"favorteCount":0,"beFavorteCount":0,"creamCount":2,"focusCount":3,"fansCount":0,"integralCount":581,"foodCouponCount":9,"lastLoginTime":0,"lastLoginIp":null,"downloadCount":0,"uploadCount":0},"newPass":null,"focusBar":null,"counter":null,"forumUserIdentificateDto":null},"theme":{"id":"1035","isDel":0,"createAt":0,"createBy":null,"createName":null,"updateAt":0,"updateBy":null,"updateName":null,"topicTypeId":"3","topicTypeName":"其他","themeName":"饮食","barType":"102","schemaName":2,"reward":0},"page":1,"favorties":true,"isSelf":false,"order":"asc"}
