I have always been the weak guy who
is afraid of donating blood, refusing every opportunity given every now and
then.
Few days back my class
representative informed us about the World Blood Donor’s Day which falls on 14 June 2013. I was hesitating whether to go or not until the day comes, when Pei
Shin asked me to go along with few other friends after class ended at 10 am. I
am used to rejecting people’s offer all these while due to the fear within me
but I tell myself on that particular moment, ‘Not this time’.
We reached the Voluntary Blood Bank
section on Kasturba Hospital after our brunch and the crowd there was
unexpectedly overwhelming. I can see my college students from all the batches
gathering there. Despite the large crowd and long queue, we waited patiently
for almost an hour before our turn.
When my name was called, I can feel
the cold sweat on my palm and I can hear the increased beating of my heart. The
feeling of witnessing my own blood being sucked out through a tube is
unimaginable, I told myself. Upon lying down on the bed, I asked the doctor on
duty, ‘Is it painful?’ ‘No’, he replied.
The syringe was inserted slowly into
the median cubital vein on my arm. Blood immediately rushed out through the
narrow tube which connects it to a sanitized plastic container with
anti-coagulant. I was given a soft ball with a smiley on it which I have to
compress it manually with my hand. The blood that was extracted is 450 ml for an
average man who weighs more than 55 kg, approximately 10% of my total blood
volume.
Surprisingly, I did not feel any
unbearable pain, nor any numbness on my arm, something which contradicts with
my fear all these while. I was instructed to stay on the bed for few minutes
after the donation and was led to a resting room where I was given an energy
drink to replenish my electrolyte and fluid balance, and a bar of kitkat.
Certificate of appreciation was
given too and an extra 3 hours of attendance will be added. Some came for donation
because of the extra 3 hours of attendance but I don’t think I need an
attendance of 103% =P
It was an amazing and painless
experience to me and I regretted for not doing this good deed in the past few
years. I do not know exactly to whom my blood will be given or how it will be
used, maybe they used it to water the plants? (just joking xD) But at least I have done my part and gave hope to those who need it. Most importantly, I overcame my own fear and accomplished yet another challenge
in my life~ =)
Medical Magic #2
The blood vessel frequently used for intravenous injection or in this case, for blood donation is located on our arm and the preferred blood vessel is called Median Cubital Vein. A vein is a blood vessel that carries blood back to the heart while artery is responsible to transport blood away from the heart.
Median cubital vein is the vein which connects the 2 main veins on our upper limb, that is the Cephalic vein and Basilic vein. This vein is preferred because the blood pressure inside is low and it lies very superficial (directly below the skin) on the surface. Some of you might be able to see the vein on your own arm whereas some will not be able to see it, how is it possible for venipuncture (taking blood) if the vein is not seen?
The Magic: A cuff from sphygmomanometer (instrument used to measure blood pressure) is usually used and tied around the forearm. This is to decrease the velocity of the venous blood from flowing back into the heart and thus causing increased pressure on the vein, exposing it on the skin surface for easier marking. Once the vein is exposed, a syringe is inserted obliquely and blood will flow out naturally.
