as a patient giving a few tubes of blood samples two times ina month for passport and visa health reports in two countries, i can say that it was more comfortable for me when they used butterfly needles because nurse fixed the needle with plaster immediately after injection and after that collected blood sample with tubes without touching it. I am not scared of needles and i just do as they say but normally while they collect blood in tube, some BAD nurses "jiggle the needle" in my vein a lot and i feel like i am going to faint with strong nausea. I hate these kind of nurses and they even blame me for this if i tell them "you play too much". Butterfly needles are lifesaver with these kind of nurses. Because it is attached to a long flexible pipe, whatever they do in the other end just wont hurt me. They take at least 3-5 tubes of samples so they need to plug and unplug tubes. If the nurse is not good skilled this process is very painful for me. believe it or not, there are nurses out there who treat you like an animal. it is really annoying.
The advantage of using two different tests is to make sure that the test has accurate results.

The advantages of using a butterfly needle to draw blood are-able to obtain specimens from infants with out having to use the heel stick method.-able to obtain a specimen more safely from a combative patient.-able to obtain the specimen from the back of the patient hand with a lower risk of nerve damage prevalent when using a straight needle in the back of the patients hand.-for incredibly difficult blood draws the phlebotomist is able to get an immediate flash to let them know that they are in the vain.the disadvantages of a butterfly needle are-the new style push button butterflies are very sensitive and the safty may release mid-draw casing a need for a second blood draw.-the needles are often very small greatly increasing the likeliness that the blood cells will be damaged casing the blood to hemolize or platelets clumping.-the butterfly with tube system requires that the needle be in the arm longer because the blood flow is much slower, also requiring the tourniquet to stay on longer increasing the likeliness of abnormal results for some tests.-if many tubes are required a second blood draw may be required because of the vacuum from the tubes being to much of a pull on the vein.- many phlebotomist experience increased vein "rolling" and "calapsing" when useing the butterfly.- the butterfly costs as much as 3x as much as a straight needle.-
