When you go in to have blood drawn, it can be hard to know what to expect. In some cases, the technician may have to poke your arm multiple times before they find a vein. In other cases, they may get lucky on the first try and be able to draw blood right away.
While there is always a chance that a person with normal veins will get unlucky and get poked more than once, there are some people whose veins are particularly difficult to find. Unfortunately, these people often have a difficult time getting their blood drawn. They may wind up having to have the blood taken out of their hand rather than their arm, simply because the veins are too difficult to find, according to vascular surgeon Dr. Halland of Vein Institute and Pain Center of America (VIP Center of America).
If you have blood work scheduled or you are donating blood for the first time, you may be wondering whether or not there is a way to tell if your veins are good or bad for having blood drawn. Sadly, there is no surefire way to tell how easy it is going to be for a nurse or lab tech to find your veins. However, there are a few things that you should keep in mind.
First, if you are overweight, it may be a bit harder for them to find your veins. This is because they are buried a bit deeper inside your body. On the other hand, if you are muscular, chances are it will be quite easy for them to find a vein. The muscles help push the veins toward the surface of your skin, making them much easier to see.
Interestingly, the weather can also have an effect on how easy it is to draw your blood. If it is a hot day, the technician will probably have a far easier time finding your veins than if it is a cold day.
Although there is no foolproof way to tell whether or not you have good or bad veins for having blood drawn, your overall body weight, your level of fitness, and the weather outside can all play a role in making it easier for a nurse or technician to find your veins.
AZT (azidothymidine) holds the record for the fastest approval of a drug by the FDA (Food and Drug Administration) in a period of just 19 months. This was due to the fact that the AIDS epidemic was reaching a critical stage in the 80’s and the first clinical trial showed that patients who were taking the placebo were dying faster.
The need to treat patients simply outweighed the need for further testing and the political climate at the time put huge pressure on the FDA to fast track testing and accelerate approval. Protests from HIV/AIDS sufferers, their families and friends was part of the reason that the FDA needed to approve the drug for mass production very quickly.
AZT is a reverse transcriptase inhibitor which simply means that it prevents the production of DNA to lower the viral load in patients. It is not a cure but rather an effective treatment, allowing patients to live longer with the disease.
Since approval on March 19, 1987, there has been much controversy regarding the lack of testing. Side effects, contraindications and interactions that weren’t noticeable after the first trial started becoming evident.
This became an issue when the drug started being used to prevent mother to child transmissions of HIV/AIDS. Although the drug was very effective, it was also related to fetal abnormalities and birth defects.
Other prominent side effects that came under debate is that AZT killed healthy cells in the body and increased the symptoms of the disease. This was fatal in some patients, especially children.
Today, drug resistant strains of HIV have meant that new and improved treatments are available. The exorbitant cost of AZT treatment has also led to it going of patent in record time which means generics are now available at a more affordable cost.
In order for us to truly understand the technological advancement in the treatment of HIV/AIDS, we need to learn more about the virus itself, it’s origins, where it came from and how it spread. This informational video will help.
