褥疮的临床表现是什么？褥疮是现在很常见的一种疾病，这种疾病给患者的生活带来很大的影响，同时也给患者的家庭造成很大的伤害，根据调查目前还有很多人不是很了解，那么关于这种疾病的临床表现是什么呢？下面一起来了解一下吧。
症状体症
1.受压部位红斑、水泡、溃疡依次出现； 2.多见于截瘫，长期慢性消耗疾患、大面积烧伤、深度昏迷的体表骨隆突部位； 3.溃疡可深及肌肉、侵犯?*亟冢ｑ袼闹芸捎星毙星幌逗婉嫉馈
诊断依据
1.多见于截瘫、慢性消耗性疾患、大面积烧伤及深度昏迷等长期卧床患者。 2.多发于氐骨、坐骨结节等骨隆突处。 3.在持续受压部位出现红斑、水泡、溃疡三步曲病理改变。
小儿烫伤的程度取决于烫伤的方式和烫伤面积。其病理变化与临床表现主要反映在局部组织和全身变化两方面。
\n(1) 局部变化：皮肤受高热后(超过60℃)，组织内蛋白即可发生凝固，以致细胞坏死。局部反应依热物的温度、接触的时间以及受伤皮肤厚薄而异。一般皮肤与70℃热物接触1s 即发生水疱，而新生儿却常因50℃的热水袋烫伤。
\n按局部组织坏死的深度小儿烫伤同样分为3 度。但由于小儿皮肤很薄，分度有困难。一般临床经验是容易估计偏低。
\n(2) 全身变化：严重烫伤者可出现休克。烫伤后早期出现休克多由于疼痛和精神刺激引起，一般为暂时性，不严重。而继发性休克是因为毛细血管渗出增加，使组织水肿和创面大量渗液，血浆损耗，血液浓缩和循环血量减少，继而出现组织缺氧、血压下降、脉搏低弱、低血钠与酸中毒、少尿或无尿等。烫伤后6～8h 内液体渗出最快，并于36～48h 达最高峰，通常超过淋巴回流的能力，以后逐渐减慢。

我们生活中总是有一些灾难从天而降，有的时候一些事情不是我们所想的那么简单，所以遇到事情以后要尽量做好一些安全措施，一般情况下，家里要是发生了烧伤就慌的不知道要怎么办了，也不知道患者是不是严重，所以大家一定要先了解烧伤的一些临床症状，好知道要怎么办。
烧伤的严重程度取决于受伤组织的范围和深度，烧伤深度可分为Ⅰ度、Ⅱ度和Ⅲ度。
烧伤Ⅰ度烧伤损伤最轻。烧伤皮肤发红、疼痛、明显触痛、有渗出或水肿。轻压受伤部位时局部变白，但没有水疱。Ⅱ度烧伤损伤较深。皮肤水疱。水疱底部呈红色或白色，充满了清澈、粘稠的液体。触痛敏感，压迫时变白。Ⅲ度烧伤损伤最深。烧伤表面可以发白、变软或者呈黑色、炭化皮革状。由于被烧皮肤变得苍白，在白皮肤人中常被误认为正常皮肤，但压迫时不再变色。破坏的红细胞可使烧伤局部皮肤呈鲜红色，偶尔有水疱，烧伤区的毛发很容易拔出，感觉减退。Ⅲ度烧伤区域一般没有痛觉。因为皮肤的神经末梢被破坏。烧伤后常常要经过几天，才能区分深Ⅱ度与Ⅲ度烧伤。
烧伤创面预后：一度创面2～3天内症状消退，3～5天全愈，脱屑，无瘢痕。浅二度如无感染，1～2星期痊愈，不留瘢痕。深二度一般3～4星期痊愈，不留瘢痕。三度创面3～4星期焦痂脱落，需要植皮后愈合，遗留瘢痕，畸形。
我们要知道烧伤的程度不同所表现出来的症状也是不一样的，所以我们应该要根据自己烧伤的程度然后选择治疗的方法，以上就是为大家介绍的关于烧伤的一些临床症状，希望能对大家有一些帮助，能及时的对患者进行正确的处理，不至于病情更严重。
生活中有很多的意外出现，大家需要注意小儿烧伤的出现，很多的孩子会出现烧伤的情况，严重的影响到了身体健康，而且还会造成皮肤粘膜受到影响，危害性非常大，所以大家需要注意不同时期的保护方法，那么，烧伤的三期症状表现是什么？
\n1、体液渗出期：为烧伤后的早期变化。轻者水肿起水泡，烧伤面积较大时，体液的丢失量也大，如治疗不及时会造成血容量减少而发生休克。渗出在36～72小时后停止而开始吸收或消肿。
\n2、急性感染期：主要来自创面的污染，加之伤后人体的抵抗力降低，细菌在创面上繁殖，导致创面感染，加重组织的损伤。细菌还随着体液的吸收进入血液引起败血症或脓毒血症。
\n3、修复期：人体的修复在创面出现炎症后不久即已开始。1度烧伤一般3～5日痊愈，不留疤痕。浅2度烧伤如无感染，半月左右痊愈，不留疤痕。深2度烧伤3～4周可痊愈，多留有疤痕。3度烧伤焦痂脱落后形成肉芽创面，须植皮才能愈合，并留有大量瘢痕。
\n根据烧伤感染的病原菌可以把烧伤感染分为以下二类：
\n1、细菌性感染
\n细菌性感染是烧伤感染最常见的致病。革兰氏阳性细菌感染随着敏感抗生素的出现，虽然发病率有所减少，但时有发生金黄色葡萄球菌感染和溶血性链球菌感染。革兰氏阳性细菌中绿脓杆菌、大肠村菌、爱德华菌、克雷白菌、变形杆菌(含吲哚阴性变形杆菌)、沙雷氏菌等引起的感染逐渐增多的趋势。随着厌氧菌的培养技术的发展，厌氧菌感染的发现率近几年也增加，常见的有无芽孢厌氧菌中产黑色素类杆菌和消化球菌所致的感染。
\n2、真菌性感染
\n由于大量或长期应用多种抗生素并发真菌感染日益增加。常见的有念珠疱疹病毒、巨细胞病毒和水痘疱疹病毒。多见于儿童的浅表烧伤创面。
