Venesection \Ve`ne*sec"tion\, n. [NL. venaesectio; L. vena vein
+ sectio section.] (Med.)
The act or operation of opening a vein for letting blood;
bloodletting; phlebotomy.
The following translation from Old English is advice given by Ambroise Paré in a 1634 text:
But blood is let by opening a vein for five respects:
the first to lessen the abundance of blood, as in plethoric bodies, and those troubled with plentitude.
The second is for diversion, or revulsion, as when a vein of the right arm is opened to stay the bleeding of the left nostril. (Huh?)
The third is to allure or draw down, as when the vein is opened in the ankle to draw down the menstrual flow in women. (Double huh?)
The fourth is for alteration or introduction of another quality, as when in sharp fevers we open a vein to breathe out that blood which is heated in vessels, and cooling the residue which remains behind. (Thank God for Panadol!)
The fifth is to prevent imminent disease, as in the spring and autumn we draw blood by opening a vein in such as are subject to spitting of blood, quinsy, pleurisy, falling sickness, apoplexy, madness, gout, or in such as are wounded, for to prevent the inflammation which is to be feared. (Still doesn't beat Ernie's idea of prophylaxis.)
Before bloodletting, if there be any excrement in the guts, they shall be evacuated by a gentle clyster, or suppository, lest the mesenteric veins should thence draw unto them any impurity.
Rapid bleeding by venesection with the patient
standing was advised. It was surmised that the
early onset of faintness and
softness of pulse was
beneficial. Slow bleeding with the patient supine led to more blood loss before the soft pulse and faintness developed, which was thought to be undesirable. Blood losses averaged
16 to 30 oz. Sufficient bleeding had occurred when the fever subsided, the pulse had become soft, or
suppuration had developed.
I wonder if people in future would have the same opinion of the way we're treating things like cancers these days. But I digress.
The word venesection is now, in the modern day, defined as the practice of removing or "letting" blood for diagnostic, rather than therapeutic reasons. This is now the only form of medicinal bloodletting that is generally practiced.
After that hefty introduction, it should be a no-brainer to guess what we did for CSU today:
Blood-taking.
The introductory briefing was quite amusing, with the chap in the blood-taking video saying, "I don't know of anyone who's been pricked by a syringe. Needle, yes, but not a syringe," and Sr. Teoh chucking syringe after syringe into the sharps bin to demonstrate proper disposal of sharps. After the dunno-how-manyth syringe was chucked into the bin -
just because Sr. Teoh had "used it" by waving it around in the air - Richard was heard to sigh, "There goes another one."
But, what Richard said was a walk in the park compared to what other people were heard to say, all while we were taking each other's blood.
Hence, I bring you the list of things you DON'T want to hear during blood-taking:
1) I've done it twice before; I didn't manage to get it the 1st time, but he let me do it again the 2nd time.
2) I didn't manage to draw any blood. I guess I'll have to do it again.
3) Should I use the big needle or the small needle?
4) Where exactly are you planning to prick?
Err... I dunno. Somewhere over there?
5) Which is the more painful vein again?
6) Wait, where's the gauze?
7) Oh, no! It moved!
8) You gotta go
really deep to make sure you don't miss the vein.
9) I already had a lot of trouble taking blood from the model hand. I hope it's easier to take blood from you. I think it should be easier with the real thing.
(Yeah, right!)
Or the all-time favourite:
10) I have no professional training.
I was the unfortunate victim of statement #1. My beloved said to me, "Don't worry. I've experience. I won't hurt you." Being a firm believer in the importance of affirming & lending support to each other, I agreed to let him draw my blood.
I've since learnt that mutual trust only goes so far in a relationship. Bloodletting ain't covered.
OK, never mind the fact that I've a phobia of needles,
(Dating from the age of 5 when the nurse, aka. my mum had to chase me around the clinic, and drag me out from behind the door where I had hidden myself in vain in order to give me my immunisation jab. Needless to say, my mum was NOT happy) and that I was tense, and that it
hurt when he slid the needle into my vein & pulled the plunger on the syringe, the best bit was when he went, "Where's the gauze?"
Statement #6.
In his rush, he pulled the needle out without loosening the cuff. Before my very eyes, blood started leaking out of my veins, and the crook of my elbow distended with blood. I was terrified.
On a side note, the blood came pouring out so quickly, I can't help but wonder if my blood is unusually fluid... hmm, better check my haematocrit level.
Somewhere amidst the commotion that erupted, Dr. Swee Jen appeared on the scene. "Press this on her hand for 5 minutes." She kept rubbing my back and telling me, "Don't worry. You'll just get a little bruise."
She did ease my trauma somewhat, but I was still pretty shaken. And yes, I cried. Hey, you don't exactly see your arm ballooning with blood everyday.
After a bit, my coagulation pathways finally kicked in, and he stuck a plaster on the crook of my elbow. To give credit to him, he apologised profusely
(and bought me lunch)... I was all set to forgive him when he remarked, "Well, at least I've left my mark on you."
Yeah, like the way a cowboy brands his cow! Why can't you get me jewellery or matching T-shirts like any other guy?
Thanks to my unusual display of foresight, I'd opted to have my left hand pricked, so I was still able to take blood from other people since my right hand was still intact. I sat down opposite him, and picked up the needle.
"Er, Sushintha. You mind drawing my blood instead? I don't like the killer look she has on her face."
I drew his blood, anyway, and thanks to Dr. Zuria's tutoring, and of course, my inborn expertise, I managed to draw his blood with considerably less fuss.
Pity.
4 hours later, my hand still aches. Good thing the futsal match has been postponed to next week, 'cos I don't think I'll do too good with this haematoma.
Sigh. The things we do for love.
Word of the day:
Bloodbath.
