在 这 次 的 献 血 活 动 里,有 一 位 献 血 者 在 献 血 之 后 突 然 感 到 不 适,晕 倒 在 外 面,看 到 献 血 者 晕 倒,我 难 免 有 点 手 忙 脚 乱,还 好 当 时 职 行 任 务 的 医 生 还 未 离 开。当 献 血 者 被 抬 到 床 上 时,我 看 到 他 的 身 体 似 乎 很 不 舒 服。医 生 不 慌 不 忙 的 为 位 献 血 者 量 血 压,查 寻 献 血 者 献 血 前 的 血 红素,经 过 医 生 检 查 后,献 血 者 的 血 红 素 是 付 合 标 准 。原 来 是 这 位 献 血 者 身 体 本 来 就 不 适。献 血 之 后,在 炎 热 的 天 气里,身 体 无 法 负 荷 而 晕 倒。
献 血 救 人故 然 是 一 项 美 举,但 是 千 万 要 确 保 自 己 的 身 体 健 康,没 有 出 现 任 何 状 况,才 来 捐 血 哦。。

采访记 - 零的突破



今天(九月21日)是一个充满记念性的日子,因为是我第一次献血。
身为义工的我虽然对献血的过程了如指掌,但是第一次献血,心情难免会七上八落,还好有一群经验丰富的医务人员为我 注入强心针,他们的爱心和耐性让我能抛开一切顾虑,献出我的第一滴血。
当看着鲜红的血液从自己的血管里汩汩流出,想着它能为挽救一个生命做出一点微薄贡献的时候心里感到饱饱的成就感,一直郁闷的心情突然也轻松了许多。
那一刻的我感觉特别温暖,自己的血液能在另一个人身上流淌是多么幸福的感觉呀。我可以很光荣并大声的对你们说‘我已成功的踏出献血的第一步了,你们也一样可以哦。’

通过献血,让我对自己的人生和态度都有了更深刻的认识,我感受到了人间的真情,幸福与温馨。

救人一命,胜造七级浮屠。。

Blood Donation Campaign @ 21-Sep-2008


There was good response to today's Blood Donation Campaign, 256 donors turned-up to support the event. It must be a timely boost to local blood banks, especially during the Muslim Puasa Month.

今天的献血运动的反应蛮不错,谢谢256位热血人士的响应。在回教徒斋戒月时期,本地血库都面对血液短缺,这些善心人士及时提高了血液的存量。

To our Muslim friends, Selamant Berpuasa.

疯牛症

非典型克雅二氏症(vCJD)就是人类的疯牛症,被普遍认为是经由食用感染变性蛋白质的牛肉所引起,在一九八○年代和一九九○年代初期特别常见于英国。

2004年英国通报,在二十多名因接受感染克雅二氏症捐血人的输血而被认定有遭感染危险的民众中,出现两名疑似遭感染病例。而七日发表的对第三名因输血死亡病患的死因分析报告,显示输血十分容易传播疯牛症。没有人知道过去有多少患者捐了血或仍在捐血。

三宗死亡案例的证据显示,疯牛症如果是通过输血传染,潜伏期仅为六至七年。通过吃问题牛肉而感染的疯牛症,潜伏期要长得多。第三位因输血而感染疯牛症的病人,他在接受手术七年后发病,开始出现身体摇晃倾向、记忆减退、手部颤抖和腿部严重疼痛等初期症状。该病人在一年后死去,年仅三十一岁。经大脑解剖、并在扁桃腺作蛋白质病原体检测后,证实是感染非典型克雅二氏症。

无症状潜在患者数千

疯牛症可经由血液传播要比吃到问题牛肉感染来得更容易,因为吃了受污染的牛肉之后,变性蛋白质还必须克服动物与人之间的「物种屏障」才会传播给人类。迄今,已有约一百六十人因食用受感染的牛肉而死于疯牛症,死者多数是年轻人。

当局为防止透过血液传播,已开始从美国进口血浆,禁止接受过输血和血液曾输给后来染上非典型克雅二氏症的人捐血,并清除所有的血液组成部分的白细胞,科学家相信最有可能携带变性蛋白质病原体的就是白细胞。

然而,不进行测试是无法鉴别所有捐献血液的,而且目前仍无法确知究竟有多少潜在的问题捐血者。非典型克雅二氏症的潜伏期是如此的长,以至足以有大量机会让一名捐血者携带著变性蛋白质病原体多年而不自知。

Mad Cow Disease (BSE) and Blood Donation

Mad Cow Disease or BSE (Bovine Spongiform Encephalopathy). It's called mad cow disease because it affects a cow's nervous system, causing a cow to act strangely and lose control of its ability to do normal things, such as walk. Experts have found a link between BSE and a rare brain condition that affects people, called variant Creutzfeldt-Jakob disease (CJD). Researchers believe that people who eat beef from cows that have BSE are at risk of developing a form of CJD.
CJD is caused by an abnormal type of protein in the brain called a prion. When people have CJD, cells in the brain die until the brain eventually has a "sponge-like" appearance. During this time, people with the disease gradually lose control of their mental and physical capabilities.
By November 2006, only 200 cases of this rare condition (vCJD) had been reported worldwide. Of these, most were identified in Britain. Several of the people diagnosed with the disease outside Britain — including two cases in the United States — had a history of exposure in Britain.
As There is no test for vCJD in humans that could be used to screen blood donors and to protect the blood supply, US and many parts of the world stipulated the following are not eligible to donate blood :
Live, visited or having blood transfusion in UK during January 1, 1980 through December 31, 1996.

What is G6PD deficiency?



Glucose 6-phosphate dehydrogenase (G6PD) deficiency is an enzyme deficiency of the red blood cells. G6PD deficiency leads to an abnormal rupture (breakage) of the red blood cells called hemolytic anemia (abnormally low red blood cell count).

What is the cause of G6PD deficiency?

The abnormal gene responsible for this inherited enzyme deficiency is located on the X-chromosome. Therefore, the illnesses associated with G6PD deficiency occur more frequently in males than females, since males only have one X-chromosome. There are different degress of G6PD deficiency, which vary according to the magnitude of the missing enzyme.
Usually, the hemolytic anemia occurs after exposure to certain compounds with oxidant properties, including drugs such as malaria medications, sulfonamides, antiitching drugs, dapsone, and others. Compounds with the property of inducing hemolysis in G6PD deficient persons are also found in the fava bean. This condition, known as favism, occurs within a day of ingestion of the fava bean. Favism can cause fever, back pain, headache, nause, and chills.

Can they donate Blood ?

G6PD deficiency is a genetic blood disorder. It is an inherited condition that affects the body’s red blood cells.
The great majority of people with G6PD deficiency are healthy and do not experience any symptoms clinically. As such, they are still allowed to make blood donations. However we usually would advise donors with G6PD deficiency to donate plasma or platelets via apheresis technique instead of whole blood. RBC donations are not recommended as their bone marrow is already working hard to compensate for their condition and we do not want to further exhaust their marrow. The red blood cells of those with G6PD deficiency are also more fragile. These red blood cells have a shorter lifespan and hence would not be suitable for transfusion to anaemic patients.

SEGI College Support Call to save life

During the just concluded 147th Blood Donation Campaign held on last Sunday, we welcome the students from SEGI College to respond to our call to save life. There were more than 30 of them, which I was told will be the future tour guides to boost our Penang tourism. As Georgetown has been listed as World Heritage, we certainly need more of these young and energetic people.

在刚结束的147期献血运动中,我们得到槟城SEGI学院的响应。这些就读导游课程的学生显示了他们勇敢和有爱心的一面,为这社会付出了一包包宝贵的血液。一行人在老师的带领下,完成了这项壮举。
乔治市已经被列入了世界古迹,正是须要这班生力军来推动槟州旅游业的时候。就看他们了!

什么是“G6PD缺乏症”?


这是蚕豆。有些人却不可以吃,还有它和捐血有什么关系呢?


Glucose 6-phosphate dehydrogenase (G6PD) deficiency

(缺乏六磷酸葡萄糖脱氢或简称酵素缺乏〕


G6PD缺乏症俗稱蚕豆病,是一种遗传性代谢缺陷,为X伴性不完全显性遗传,男性发病多于女性。G6PD的作用主要是維持紅血球的穩定,減少紅血球受侵襲時被破壞的一種酵素,其作用相等於一個國家的軍隊:閒時作用有限,但國家安全受威脅時則會發揮極大的保護作用。

由于G6PD缺乏症变异型很多,临床表现差异极大,轻型得可无任何症状,重型者可表现为先天性非球形红细胞溶血性贫血,一般多表现为服用某些药物、蚕豆或在感染后诱发急性溶血,重得可危及生命。


患者是可以将此病传给下一代的,规律是:父亲患病,可以传给女儿,不传给儿子;母亲患病,可以传给约半数的女儿和儿子。一般女性G6PD缺乏程度较轻,而男性较易发生溶血,还应注意的是:父母有这种酶缺乏时,婴儿出生时应留脐血检查,如不及时发现,并采取预防措施,婴儿很可能产生新生儿黄疸,造成终生智力低下。因此,进行产前诊断、治疗和新生儿疾病筛查及为重要。


除了忌吃蚕豆亦切忌服用西藥如亞士匹靈維他命K中藥如川蓮麻黃等另一方面患者最好避免經常接近含臭丸或樟腦氣味之物件/場所

G6PD缺乏症的发病机制中涉及到一个重要的还原性物质 NADPHG6PD缺乏者因不能产生足够的NADPH,故服用氧化性药物或蚕豆之后,产生过多的过氧化氢不能及时被还原,造成红细胞破坏而致急性溶血, 典型的是伯氨喹啉,多数解热镇痛消炎药也有氧化性。


誘使G6PD缺乏者發病之因素
1.
嗅覺、觸覺因素:─→特別是臭丸、樟腦、冬青油、萬金油和顏料等。
2.
食物:─→G6PD缺乏症也稱為「蚕豆病」,故名思義,蚕豆便是一主要的病發誘因,尤以新鮮蚕豆為甚。在農村,吸入蚕豆收成季節的花粉,亦曾會影響此病發生。
3.
中藥:─→包括牛黃、川蓮、臘梅花及珍珠末、金銀花、熊膽等,個別項目應請教醫生。
4.
西藥:─→西藥中也有很多會令酵素溶解而缺乏的,種類過百難以盡錄,應個別請教醫生,最常見的包括阿斯匹靈(水楊酸),這包括口服及塞肛、退燒的亞士匹靈、抗瘧藥、氯霉素、水溶維生素K3、磺胺等。
5.
其他因素:─→包括新生期、感染、缺氧、腦出血、糖尿等亦會令G6PD缺乏症病發。一般上有G6PD缺乏症者都须要戴说明手鍊或頸鍊方便辨认.


患者可以捐血吗 ?

对于这点,议论纷纷,有人说可以,也有人说不可以。我请教了本地的血库单位, 答案是可以,但不被鼓励。对患者本身,会加重骨髓造血的负担,而捐出的血也可能会使接受者有不良反应。

Donate Blood & Organ is a family affair








Last Sunday blood donation drive, we managed to collect 262 pints of blood, out of 285 turn-out. What was impressed me was a little girl who wanted to pledge her organs, and she is only 12 years old.
在上个星期日的献血运动,有285人响应,而我们成功筹获262包血液,令我印象深刻的是一位小女孩要认捐器官,而她今年才12岁而已。

We always encourage the blood donors to bring along their family members, to treat it as a family day. Beside getting the blood, we want to nurture the young children to care about the societies.
所以说我们常常都鼓励献血者把这一天当成家庭日,带一家大小来献血。除了拿到血液,我们也可以培养孩子怎样地去爱这个社会。

20 July 2008

*********** 施与受皆大欢喜 ***********

我想献血对大家一点都不陌生吧!我从学院时已加入献血的行列了,屈指数数,也应该也是好多年前的事了。毕业之后,每三到四个月我总是留意报纸所刊登的献血活动,把宝贵的血液捐给所需要的人。每一次捐血,那一种满满的满足感总会油然而生。直到在一次偶然的机会下,我正式加入慧音社的献血团,友善的义工们让我留下深刻印象,决定把多余的时间献给献血团。虽然大家各有各忙,但是每一个月的献血日总会准时到慧音社帮忙。

无论你是想加入献血团或成为我们的义工,我们都以万二分的谢意来欢迎你,别犹豫了,快快加入我们的行列吧!

“施与受皆大欢喜”

Washing Blood Donation Beds

Got up at 8am this morning. And that's early for me for a non-blood donation Sunday morning! Got a lift from Liling Jie and arrived at Hui Yin Seh slightly over 9am. Sengling Ge and Lili Jie were already there all prepared! Beds all lined up with scrubs and soap-powder! Then Tangxin Ge arrived with his water pump and we were all ready to go!

We (the girls) were scrubing while the guys were busy moving the beds to rinse and to dry in the sun! When YiHao Ge and Meiliang Jie arrived, Lili Jie joked " Yeah, more domestics maids to come to help us with our tasks!"
Haha... Although there were lots beds to be cleaned, time just flew past as while doing our tasks, everyone was happily chatting and merrily joking and catching up with the happenings with each other. It's really hard for us to chat/bond with each other much as usually we tend to get quite busy on blood donation days!

Here's the proof to show we were working hard!


And the nicely lined up clean pillows and beds having their sunbath!

Well, the sun was really co-operative as well! We managed to get everything dry and stacked up neatly by the time it started to pour! We rested a little while before proceeding to our next activity, the durian party in the rain,which will be posted by Liling.
Thank you everyone who has helped out! Blood donors will have a clean bed to lie on next week!

Suppliments After Blood Donation



I was often been asked by some blood donors :
"why doctors give me this pills ? what are they ?"
Well, it's good to understand before you take this pills and can sleep well.

Iron


Is necessary to make hemoglobin, the protein needed to carry oxygen throughout the body, and helps to increase resistance as well as increase energy production. Iron supplements may cause the stool to turn black or gray, but this is normal unless it contains blood.

Taking a Vitamin C supplements Along with the iron helps the iron absorption. Iron works effectively with B-12 and Folic Acid.

Beside the supplements, you can find iron in liver, lean meats, eggs, whole grain breads and cereals, fruits, vegetables, and brewer’s yeast.

Vitamin C

Vitamin C strengthens the capillaries and cell walls and is essential for collagen formation. It functions in protein synthesis by changing the charge of iron so that it can be absorbed, and it works as an antioxidant. Vitamin C functions in the construction of protein from amino acids.

Folic Acid

Folic Acid is used to make blood cells, build muscle, and heal wounds. It is necessary for every function requiring cell division to make sure cells duplicate correctly.

Vitamin B

In general, the B vitamins family facilitates the metabolization of food for energy and fosters many bodily processes that pertain to physical and mental functions, energy and proper nerve functioning.

Health benefits of donating blood



  • Reduce the chance of heart diseases
    It has been observed that increase in blood iron level increases the chance of heart disease. Iron is involved in the oxidation of cholesterol and this process is believed to be detrimental for the arteries. Increases blood iron level favors this process of cholesterol oxidation and thus leads to heart disease. Regular blood donation helps especially males in loosing iron on regular basis. It helps in reducing the chance of heart attack to one third.

  • Enhance the production of new Red Blood Cells
    As the blood is withdrawn from the donors' body there is decreasing in blood cells. To replenish it, immediately new cells are produced by marrow and this way blood gets refreshed. Therefore donating blood helps in stimulating generation of new blood cells.

  • Helps in fighting hemochromitosis
    Hemochromitosis is a genetic disorder; also known as iron overload disorder wherein iron accumulates in the body tissue because or improper iron metabolism. This condition may lead to organ damage. Though this problem is uncommon in Indians, people with little iron overload also can easily donation blood and reduce their iron content. Taking example from other countries, one in every 300-400 people in England suffers from this disorder and American Red Cross blood services accept such donors as safe donor as it’s a genetic disorder, it won’t be harmful to the person receiving blood from such donors.

  • Burns calories
    One can diet or remain fit by donating blood regularly. One pint of blood (450 ml) when donated burns 650 calories in donor’s body.

  • Invigorated feeling in elderly people
    It has been mentioned in various sites though not proved that elderly people in good health have reported feeling invigorated or reenergized by giving blood on a regular basis.

  • Basic blood test is done
    Apart from all these benefits a donor gets a mini blood test done before donating blood. This includes Hematocrit i.e. HB level test, Blood pressure is measured, body weight is checked. After the blood is collected, it will be tested for 4 major diseases. Those are Hepatitis B, Hepatitis C, HIV, and Syphilis. Donor is immediately informed if any of these test found to be positive.

Helpful Tips For a Successful Donation

Before donating :

  • Get a lot of rest the night before your donation.
  • Have a good breakfast and/or lunch but avoid fatty foods. Fatty materials (lipids) remain in your blood for several hours and may prevent the proper testing of your blood. Eat iron rich foods such as beans, iron-fortified cereals, green leafy vegetables, raisins.
  • 24 hours prior to donating, begin drinking lots of liquids (especially water) – avoid caffeinated beverages.

At the donation site:

  • Relax, feeling good as you are going to save a life.
  • Rest for 10-15 mins in donation bed immediately after donating blood.

After donating:

  • Drink plenty of fluids over the next 24-48 hours.
  • Take the supplements Vitamin-C and Iron (provided by Blood Bank) if necessary.
  • Avoid strenuous activity or heavy lifting for 12 hours after the donation.

Blood Donor Eligibility Guide

The criteria for donor acceptance are:

  1. Age : between 18 to 60 years.
    Note 1: a written consent from the parents/guardians is compulsory for donors over 17, but less than 18 years old. Note 2: Those above 55 years old but never donated before may be rejected.
  2. Weight : Minimum 45 kg (100 LB).
  3. General appearance : Donors must appear to be in good health.
  4. Medical history : Donors must not have a history of recent illnesses nor a history of the consumption of any medication. In addition to this they must not have a history of any inherited bleeding disorder.
  5. Donors must not have any blood related diseases, eg: Hepatitis B, Hepatitis C, AIDS Syphilis etc…
  6. Donors must not be in the following high risk group:
    i. Drugs abuser
    ii. Homosexual or Bisexual
    iii. Have sexual partners with both group mentioned.
  7. Hemoglobin level must be more than 12.5g/dl. Some private hospitals may require higher Hemoglobin level.


This list is not complete. Medical professionals are available and details of each donor's health and activities are discussed in a confidential setting prior to blood donation. The final determination of eligibility is made at that time.

For further information, donors can also refer to our Pusat Darah Negara (PDN) guidelines.

2008 Calendar - Blood Donation Campaign @ Penang Hui Yin Seh

Whole Blood and Blood Components


Blood may be transfused as whole blood or as one of its components. Because patients seldom require all of the components of whole blood, it makes sense to transfuse only that portion needed by the patient for a specific condition or disease. This treatment, referred to as “blood component therapy,” allows several patients to benefit from one unit of donated whole blood. Blood components include red blood cells, white blood cells, plasma and platelets. Up to four components may be derived from one unit of blood.

Red Blood Cells
Red blood cells are perhaps the most recognizable component of whole blood. Red blood cells contain hemoglobin, a complex iron-containing protein that carries oxygen throughout the body and gives blood its red color. The percentage of blood volume composed of red blood cells is called the “hematocrit.” The average hematocrit in an adult male is 47 percent. There are about one billion red blood cells in two to three drops of blood, and, for every 600 red blood cells, there are about 40 platelets and one white cell. Manufactured in the bone marrow, red blood cells are continuously being produced and broken down. They live for approximately 120 days in the circulatory system and are eventually removed by the spleen.

White blood cells
White blood cells are responsible for protecting the body from invasion by foreign substances such as bacteria, fungi, and viruses. The majority of white blood cells are produced in the bone marrow, where they outnumber red blood cells by two to one. However, in the blood stream, there are about 600 red blood cells for every white blood cell. There are several types of white blood cells; Granulocytes and macrophages protect against infection by surrounding and destroying invading bacteria and viruses, and lymphocytes aid in immune defense.

Plasma
Plasma is the liquid portion of the blood — a protein-salt solution in which red and white blood cells and platelets are suspended. Plasma, which is 90 percent water, constitutes about 55 percent of blood volume. Plasma contains albumin (the chief protein constituent), fibrinogen (responsible, in part, for the clotting of blood), globulins (including antibodies), and other clotting proteins. Plasma serves a variety of functions, from maintaining a satisfactory blood pressure and volume to supplying critical proteins for blood clotting and immunity. It also serves as the medium of exchange for vital minerals such as sodium and potassium, thus helping maintain a proper balance in the body, which is critical to cell function. Plasma is obtained by separating the liquid portion of blood from the cells. Plasma is usually not used for transfusion purpose but is fractionated (separated) into specific products such as albumin, specific clotting factor concentrates and IVIG (intravenous immune globulin).

Platelets
Platelets (or thrombocytes) are very small cellular components of blood that help the clotting process by sticking to the lining of blood vessels. Platelets are made in the bone marrow and survive in the circulatory system for an average of 9–10 days before being removed from the body by the spleen. The platelet is vital to life, because it helps prevent massive blood loss resulting from trauma, as well as blood vessel leakage that would otherwise occur in the course of normal, day-to-day activity. Units of platelets are prepared by using a centrifuge to separate the platelet-rich plasma from the donated unit of whole blood. The platelet-rich plasma is then centrifuged again to concentrate the platelets further.

Blood Groups

Every donor's blood belongs to one of the four main groups A, B, AB and O, known as the ABO system. These groups depend for their identification on the presence or absence of chemical substances called antigens on the person's red blood cells.

After the ABO system, the most important is the Rhesus system or RH system. The RH groups are more complicated, but most donors can be simply classified as Rh Positive or Rh Negative.

As each system is inherited independently of the other, it means that there are eight main blood groups: A+, A-, B+, B-, AB+, AB-, O+ and O-.

The Donor/Receiver chart below shows the compatibility of different blood groups. From this you can see that O- blood is the universal donor while AB+ is the universal receiver.

Blood GroupDonate toReceive from
A+A+, AB+ A+, A-, O+, O-
O+O+, A+, B+, AB+O+, O-
B+B+, AB+ B+, B-,O+, O-
AB+AB+All groups
A-A+, A-, AB+, AB-A-, O-
O-All groupsO-
B-B+, B-, AB+, AB-B-, O-
AB-AB+, AB-AB-, A-, B-, O-

How Are Blood Groups Inherited?

Blood groups for each individual are determined by genes which are inherited from both parents. Genes for the Rh negative and O groups from one parent are masked by the presence of Rh positive and A or B genes from the other parent. Thus people who are apparently A or B Rh positive may also carry genes for the O and Rh negative blood groups which can be inherited by their children.

Are There Any Other Blood Groups? There are 15 other blood group systems - in all almost 400 antigens have been discovered. However, most of these do not normally require matching for transfusion purposes.

Rh blood grouping

The RhD antigen is also important in determining a person's blood type. The terms "positive" or "negative" refer to either the presence or absence of the RhD antigen irrespective of the presence or absence of the other antigens of the Rhesus system. Anti-RhD is not usually a naturally occurring antibody as the Anti-A and Anti-B antibodies are. Cross-matching for the RhD antigen is extremely important, because the RhD antigen is immunogenic, meaning that a person who is RhD negative is very likely to make Anti-RhD when exposed to the RhD antigen (perhaps through either transfusion or pregnancy). Once an individual is sensitised to RhD antigens their blood will contain RhD IgG antibodies which can bind to RhD positive RBCs and may cross the placenta.

负血型和CDE的关系

有人检查了血型,知道自己是负血型,但当要捐血给另一位负血型者时,却被告知本身是正血型的,是不是莫名其妙呢?还是觉得当时验血型时验错?

让我尝试解释一下. 大家可能知道A血型有A抗原,B血型有B抗原,但可能不晓得还有C,DE抗原吧!普通捐血或验血时,血库只是检查血型(ABO)Rhesus (D抗原)而已,即有D抗原者属正血型(RH positive), D抗原者属负血型(RH negative).这就是所谓的Rhesus Factor.

Rhesus Factor并不能100% 把你归纳成真正的负血型者,你还要经过
CDE抗原的检查(其实是5种抗原即C,c,D,E,e).当你红血球内没有这
5种抗原后,你才是负血型者,才可以捐血给另一位负血型者.

如果你是RH negative CDE positive 的话,你必须只能接受负血型,却不能捐血给负血型者.

以上如有错误,请专业人士更正.

捐血的一些疑惑


捐血问答

问 : 捐血會不會感染疾病?
答 : 血库规定所使用的採血及相關醫療器械均是一人一套,且經嚴格消毒滅菌;用完即丟棄,不再重複使用,因此捐血絕對不會感染任何疾病。

问 : 感冒是否可捐血?
答 : 一般來說,捐血必須在身體健康良好狀況下才可以。感冒期間常併發呼吸道感染;且身體處於不舒服的情況下,因此,請捐血人痊癒後再捐血為宜。另外,如有服用感冒藥,請停藥1週後再捐血。

问 : 常聽人家說:「捐血就是失血」,是真的嗎?
答 : 捐血雖然是將血液抽出體外,但一次抽出的量有一定的限制,是不會影響健康的。一個健康的成年人,全身的血量大約是體重的十三分之一,如果體重65公斤的人,全身血量約5,000毫升,假如一次捐血450毫升,只占全身血液的11%;而且很快再補充新血,因此,對一個健康的人來說,捐血是不會有影響的。

问 : 穿耳洞、針灸、刺青者,是否可捐血?
答 : 安全起见,一律暫緩1年才能捐血。

问 : 我自己這樣瘦弱,是否可以捐血?
答 : 祗要你年齡為十八歲至六十歲而又健康,體重在45公斤以上,便可以捐血。

问 : 捐血痛不痛?
答 : 在捐血前,医药人员會在打針部位注射少許麻醉藥,使捐血時沒有不舒服的感覺。

问 : 如果我最近身體不適及曾服食藥物,可否捐血?
答 : 在一般情況下,如需定期服藥的人士或許不適宜捐血,如有問題,請先向當值医药人员查詢。

问 : 我可否藉捐血來測試有否任何傳染病如愛滋病?
答 : 千万不要!切勿藉捐血來測試愛滋病或其他傳染病,因感染初期,傳染病(包括愛滋病)血液測試仍可能呈陰性反應 .

问 : 捐血後會否致肥?
答 : 捐血和體重增減無關。

问 : 我自己都贫血了,怎能捐血呢?
答 : 许多人以为自己贫血。其实,是否贫血,等测量过血色素、红血球的数目与形态以后才能确定。

问 : 我很愿意捐血,但是实在太忙了,抽不出时间。
答 : 如果您急需输血,而有人这么说的话,您做何感想?别人的生命又值不值您十几分钟的时间?

问 : 是不是献了一次血后,就必须不停地献血?
答 : 献血后不会使机体以不正常的速度生产血液,更不会因血液生产过多而迫使您不停地献血,因为献一次血,对机体造血机能的影响与出一次鼻血、经过一次月经、受一次小外伤没有什么不同。

问 : 想献血但勇气不够怎么办?
答 : 鼓起勇气吧,您奉献的血液,体现出您的人道主义精神,对于病情危重的婴儿,意外事故中的伤员,许多等待手术的病人……则意味着再一次的生命。

问 : 为什么有些人捐血后会晕?
答 : 很多原因。一些是心理因素,尤其是第一次捐血者。另外,捐血前休息不够或捐血后太快起身(应该躺着15分钟)也是主要的原因。

2008年献血日主题为“定期献血”

Blood Basics


What is Blood?


Blood is a liquid that circulates throughout the body, carrying oxygen and nutrients to every cell, and carrying away waster products. Blood plays a central role in the body’s defense against intruders.

Blood is pumped by the heart, through a network of miles of blood vessels, to every part of the body. It accounts for 7% of the human body weight, with an average density of approximately 1060 kg/m³. (pure water's density is 1000 kg/m³). The average adult has a blood volume of roughly 5 litres, composed of plasma and several kinds of cells (occasionally called corpuscles); these formed elements of the blood are erythrocytes (red blood cells), leukocytes (white blood cells) and thrombocytes (platelets). By volume the red blood cells constitute about 45% of whole blood, the plasma constitutes about 55%, and white cells constitute a minute volume.

Blood performs many important functions within the body including:

  • Supply of oxygen to tissues (bound to hemoglobin which is carried in red cells)
  • Supply of nutrients such as amino acids, gluscose and fatty acids(dissolved in the blood or bound to plasma proteins)
  • Removal of waste such as carbon dioxide, urea and lactic acid
  • Immunological functions, including circulation of white cells, and detection of foreign material by antibodies
  • Coagulation, which is one part of the body's self-repair mechanism
  • Messenger functions, including the transport of hormones and the signaling of tissue damage
  • Regulation of body pH (the normal pH of blood is in the range of 7.35 - 7.45)
  • Regulation of core body temperature
  • Hydraullic functions

The Origins of Blood

Blood is produced in the bone marrow, a jellylike substance inside the bones. In adults, the spine, ribs, and pelvis are the primary bones that make blood. As the blood cells develop from the stem cells in the marrow, they seep into the blood that passes through the bones and on into the bloodstream.
The different blood cells have different life spans — red blood cells last about 120 days in the bloodstream; platelets about 10 days; and the various kinds of white blood cells can last from days to years.
The body has feedback systems that tell it when to make new blood cells. For example, if bodily oxygen levels are low, the kidneys produce a hormone called erythropoietin, which stimulates the stem cells in the marrow to produce more red blood cells.

Can you accumulate and store blood?

Blood has a limited shelf life.

  • Whole blood may be stored for 35 days.
  • Red blood cells may be stored under refrigeration for a maximum of 42 days.
  • Platelets must be used within 5 days of donation.
  • Plasma is generally frozen and must be used within one year.

Because blood is perishable, new donations are needed every day.

捐血好处多


大量科学研究证明献血有益健康。

一、可预防、缓解高粘血症

科学家们运用血液流变学与血液动力学对血液与献血的关系作了研究,发现坚持长期适量献血,特别是单献红细胞和血小板等有形成分,可使血液粘稠度明显降低,加快血液流速,脑血流量提高,从而达到缓解或预防高粘血症,使人感到身体轻松、头脑清醒、精力充沛。

二、可预防、降低心脑血管病的发生

青岛一位专家曾对127名多次献血者、87例高血压者、60例缺血性中风者进行血液流变学的对照研究,结果表明,献血者对减少心脑血管病的发生具有积极的作用;芬兰一研究小组对278名42-60岁的男性进行调查,其中献过血的人5年后患冠心病的比例比未献过血的少86%;另一组研究,对献血l-2次的1532人进行追踪观察,结果仅一人发生急性心肌梗塞,发生率为 0.043%,同期未献血的2306人中,有226人发生急性心肌梗塞,发生率为9.8%,明显高于献血组;美国一心血管病研究小组的研究亦表明,在3年中,献血者(男性)患心血管病的危险仅为未献血者的 1/2。

三、男子献血可减少癌症的发生率

体内铁元素含量过低易患缺铁性贫血及行动迟缓,过高则适得其反。《国际癌症》曾报道,体内的铁含量超过正常值的10%,罹患癌症的机率就提高,适量献血可以预防癌症。该文还提到,女性因月经周期失血损失了一定量的铁质,故未发现女性的铁含量与癌症发生有明显关系。

四、可促进、改善心理健康

大量研究表明,健康的情绪可通过神经、体液、内分泌系统沟通大脑及其他组织与器官,使其处于良好的状态,有益于人体免疫力的增强、抵抗力的提高。而献血是救人一命的高尚品行,在助人为乐、与人为善的同时,也使自己的精神得到净化,心灵得到慰藉,工作与生活更加充实。做好事者以德施善,实际上在帮助别人的同时也帮助了自己,这是健康长寿的重要要素。

五、可延年益寿

国外也曾有学者对66岁以上的332人(献血者)与同年龄、性别的399人(未献血者)作前瞻性对照研究,结果显示: 献血组平均寿命为70.1岁,高于未献血组的平均 67.5岁; 献血组的存活率为67%,高于未献血组的40%; 献血组的死亡率为33%,低于未献血组的60%。

献血须注意事项

  • 前一天须有足够的睡眠和休息.


  • 前4小时内有进食, 但不宜过饱.


  • 献血前多喝一些饮料如果汁,鲜奶等.


  • 献血前請勿食用油膩食物。


  • 献血后不要马上起床,须休息10到15分钟.


  • 献血后必须不断补充水分.


  • 献血后12小时内不要做激烈运动.

  • 献血后可摄取含铁质及维他素C的食物

献血者的基本条件

  1. 无论男女, 只要身体健康, 年龄介于18至60岁.
    17岁者需要父母(任何一位)签名, 医院会提供一张表格. 55岁以上而没捐过血者,可能会不被接受献血。

  2. 没有患上通过血液传染的疾病如 :
    a). B型肝炎
    b). C型肝炎
    c). 爱滋病
    d). 梅毒等

  3. 被医药人员证实身体健康即 :
    没患上 : 高血压, 糖尿病, 任何心脏疾病等.

  4. 体重至少45KG
    因为血液约是体重的1/13,约轻者血液就会相对的减少,捐了对你会有难于意料的危险性。

  5. 血红素高过 12.5 公克 / 百毫升.

  6. 不属于任何高风险群即 :
    a). 吸毒者
    b). 有同性或双性性行为者

  9. 最近24小時內未拔牙者.

  10. 最近6个月没动手术或接受输血。

  11. 最近21天没有接受打针或使用抗生素之类的药物。

「全血」和「成分血」

「全血」就是血液的全部,包含有紅血球、白血球、血小板、血漿及凝血因子等各種成分。

「成分血」則是利用離心的原理,將各種血液成分個別分開製備的血品。

針對病人的需求提供各種不同的血液成分,不但可以達到最好的療效;同時也充分運用寶貴的血液資源。通常一袋全血可分為血漿、紅血球及血小板,分別提供不同的病人輸用。

血液成份

全血
主要救活 : 急性大量失血, 新生嬰兒換血及兒科心臟手術















紅血球

主要救活 : 貧血














血小板
主要救活 : 因血小板過少或質變而引致流血不止(骨痛热症,癌症,移植器官等)














血漿

主要救活 : 燒傷、肝病
















白血球

主要救活 :嚴重細菌感染

----------------------------------------------------

关于捐成分血

1.什麼是分離術捐血 ?
(Apheresis) 这是一种另类的献血方式,是将献血者的血液抽出,在密封无菌的离心钵内,藉由血液分离机分离出血小板或血浆等血液成分;其他成分(如红血球)立刻送回捐血者体内。因为献血时间较长,需要预约且必须使用分离机设备,目前大致在政府血库才能提供这项服务。

2.分离术献血分为那几种 ?
分离术献血可分为4种:「分离术血浆」、「分离术血小板」、「减低白血球分离术血小板」及「分离术血小板兼收血浆」等。其中「分离术血浆」作业约需45分钟;「分离术血小板」、「减低白血球分离术血小板」及「分离术血小板兼收血浆」约需2小时。

3.谁可做分离术献血 ?
曾献过血,且检验报告正常者,即可参加「分离术献血」。

4.「分离术献血」的条件与「全血」献血有何不同 ?
「全血」献血条件:体重45公斤以上,可捐350至450毫升,献血间隔期为90天或以上.
「分离术献血」条件:曾献过血,且检验报告正常者;献血间隔期为2周以上。一年最多可献血24次。

5.首次献血者是否可参加分离术献血 ?
为顾虑献血者心理及血液安全等因素,分离术献血尽量避免首次献血者。

6.分离术献血对身体有什么影响 ?
分离术献血主要在更有效的运用血液资源,凡符合献血健康条件者,对身体都不会有影响。

7.分离术献血是把血液的一种成分抽出,是否会照成献血者的血液成分不平衡 ?
所抽出的血液成分在短时间之内即可重新补足,只要依规定的献血间隔期,不会造成血液成分不平衡。

8.红血球在分离的过程中,是否易受伤破损,进而影响献血者健康 ?
目前之分离机在正常操作下,不会损伤血球,也不会影响献血者的健康。

9.分离术献血为什么要事先预约 ?
由于分离术献血须用分离机来完成,目前医院血库的设备有限;且献血所需时间较长,大约45分钟至2小时,故需事先预约,才不会浪费献血者宝贵的时间。

10.为什么需要分离术血小板 ?
一般病人每次输用的血小板量,必须从6袋全血分离而得;但以分离术血小板献血时,一位献血者即足以供给病患一次输用所需的血小板量,减少病人因输用多数人血液可能产生的不良反应。这种献血方式己日渐普遍,并提升了一些出血性疾病(合并血小板减少症)治疗的成功率。

11.那些病人需要分离术血小板 ?
  1. 白血球、紫斑症或化学疗法等所引起的血小板减少症。 
  2. 发生HLA异体免疫反应而照成一般血小板输血失效的病人。 
  3. 接受接受骨髓移植的病人。 
  4. 凡有需要多次输用血小板的病人 (如骨痛热症)。
