你以为采手指血很简单,其实也是门‘技术活’

2019-02-24 俞小慧 检验医学网

我们都知道,采血分为静脉采血、皮肤采血、真空采血。工作中运用最多的主要是前两种,采手指血就是属于皮肤采血,曾被称为毛细血管采血,是采集微动脉、微静脉和毛细血管的混合血,同时含有细胞间质和细胞内液。

这段时间在做门诊,在门诊上班无非就是每天给看病的人采手指血,做大小便。在我还没开始扎的时候有些小孩就已经哇哇大哭了,有些才几个月大的婴儿被扎后竟然如此淡定,好像不是他被扎了,还看的津津有味呢!还有些小孩很犟,哭鼻子,躺地上,蹬腿甩手能用的全用了!就是不肯扎,扎个手指真的有那么痛吗?还好我经过了几年的千锤百炼,这些我都应付的过来了。

今天跟往常一样做些同样的事,不过遇到特别的情况就是我竟然被一个来看病的中学生给夸了,说“你的技术好高超啊”。我听着有点懵,想着就采个血这么简单的操作没啥技术含量呀!我便问道“你很痛吗”?“不痛,这是我被扎手指第一次没有感觉到痛的!”我暗自窃喜,这也是我第一次被夸采血技术高超的,在每天简单的工作中也能找到一丝丝“成就感”。

作为工作了六年的“老员工”我就来说说采血需要注意的事项和自己的一些经验吧!

我们都知道,采血分为静脉采血、皮肤采血、真空采血。工作中运用最多的主要是前两种,采手指血就是属于皮肤采血,曾被称为毛细血管采血,是采集微动脉、微静脉和毛细血管的混合血,同时含有细胞间质和细胞内液。所以扎完手指后流出的第一滴血应擦去,以免造成组织液混入,影响结果的准确性。 有些病人会问可以扎中指吗?是可以,不过世界卫生组织推荐的是采集左手无名指指端内测血液,所以每次我也会尽量选取无名指进行采血,如果该手指有伤就选择其他手指进行采血,结果也不会有什么偏差。很多来做血常规的病人其实都很怕被扎,其实我自己都怕!因为扎下去的那一刻真的痛,那么怎样让痛觉减小到最低呢,让那些来检查血常规被采血的病人不那么害怕扎手指呢?

首先,扎手指的部位真的很重要,就是世界卫生组织(WHO)推荐的无名指指端内测,因为手指部位神经末梢分布丰富,不同手指所受神经的支配不同,其疼痛阈值也不尽一致。其中无名指的尺侧由尺神经支配,桡侧则由正中神经支配。如果在无名指的指尖中部取血,会使尺神经和正中神经的神经末梢同时受到刺激,那样引起的疼痛感较强。而取无名指指尖的尺侧(也就是指端内测)取血,只会牵涉尺神经末梢,因影响范围较少,所以疼痛也较轻微。

其次,在采血前,一定先按摩需采血的手指指腹,天冷的时候,最好先让他们把手搓热,把需要采血的那根手指都按摩一下,使血流通畅,然后左手相对用力按好无名指指腹,右手拿好采血针,扎的时候一定是“快、准、狠”的扎下去,不要犹豫,不要紧张,更不用担心对方会痛。以前刚毕业上门诊工作那会,怕小孩痛,没下狠心,扎轻了,结果血流不畅,只好用力挤压,采血不够的话还得重新扎一次,用力挤压的话会影响结果的准确性,而重新再扎一次又得让对方痛一次,遇到不好讲的病人就更是麻烦。上班也会遇到手指的茧子特别厚的人来检查,这时候就更要“狠心”了,而且尽快选择茧子相对薄的地方了,不然的话恐怕得扎好几针才见血了。所以再一次强调,扎手指时一定要“快、准、狠”!

最后想说一点的是,遇到那些特别犟,害怕扎手指的小朋友,最好在采血前做好工作,让他们的情绪平稳下来。因为他们不肯扎,情绪很激动,手又在乱动,这时候采的血结果会有一定的偏差。

所以在门诊上班不仅需要技术,还需要有会哄小孩子的能力啊!

空腹采血不是饥饿采血

空腹血糖可反映胰岛功能,一般代表基础胰岛素的分泌功能,是临床上常用的一个指标。但在日常生活中,有不少患者对“空腹”有诸多误解,有的认为空腹就是要饿肚子,饿得时间越长指标越准,也有的患者害怕指标会高,在抽血的前一天晚上不吃或少吃,或拖延到第二天上午10点钟以后才去抽血。其实,空腹并不是要饿肚子,人的机体有强大的自我调节功能,当身体处在饥饿状态时,体内各项机能指标都会发生变化,这样采集到的血样标本就会

献血淡季来了 北京探索采血新模式

6日上午,北京大学国际医院门诊大厅里,人们排起了长队:他们不是挂号,也不是就诊,而是来献血的。这是北京市红十字血液中心、北京大学国际医院联合中关村生命科学园及园区爱心企业连续第二年发起“生命联盟”无偿献血活动的感人一幕。冬季是献血淡季,大多数城市会面临血液中心库存血量不足的问题,北京也不例外。北京市献血办公室主任、北京市红十字血液中心主任刘江说,北京市血液的主要来源是街头采血点,然而每年11月份

手把手教你动脉采血的部位与方法

血气分析在采血前后受诸多因素直接影响检验结果,为提高血气分析检验结果的准确性,作为医护人员,必须严格正确操作,做好动脉采血的护理。正确鉴别动脉血与静脉血:静脉血由于氧合血红蛋白把氧释放到组织,而成了还原血红蛋白,同时组织代谢产物回收收入血液,使静脉血呈暗红色,而且静脉血压力低,血管搏动不明显不易触及。动脉血含有较多的氧合血红蛋白,使血呈鲜红色,压力高,动脉血管搏动较明显,容易触及。抗凝剂的合理应用

临床护理八种真空采血管区别

标准真空采头盖和标签颜色表示的采血管内添加剂种类和试验用途。这样可根据要求选择相应的盛血试管。   1.普通血清管红色头盖,采血管人不含添加剂,用于常规血清生化,血库和血清学相关检验。   2.快速血清管橘红色头盖,采血管内有促凝剂,可激活纤维蛋白酶,使可溶性纤维蛋白变为不可溶的纤维蛋白多聚体,进而形成稳定的纤维蛋白凝块。快速血清管可在5分钟内使采集的血液凝固,适用于急诊血清系列化试验。
