Medical professionals generally use the safety butterfly needles to draw blood from your veins or to get access to a vein to introduce intravenous medication in the blood. Besides this, there are also numerous other ways in which butterfly needles are used. Though some alternatives of butterfly needles are also available in the market, there are many circumstances where it is good to use such needles.
So, continue reading the article to know more about butterfly needles and their uses.
Intravenous Catheter- An Alternative Procedure
Alternatively, medical professionals can also use an intravenous catheter. It possesses a retractable needle that's completely covered inside a protective sheath. The needle is further inserted into the vein, and afterward, a button is pushed to retract the needle, and then, you have to leave the sheath or catheter.
An intravenous catheter method is different from a butterfly needle as a butterfly needle gets left in the vein as compared to a plastic sheath. Moreover, this type of needle is quite smaller in length as compared to the IV catheter.
But, there are some scenarios in which you should choose a butterfly needle rather than the intravenous catheter.
A venipuncture is done when the phlebotomist accesses a vein for drawing blood. Generally, a phlebotomist can be defined as a medical professional who works for drawing blood.
For this procedure, butterfly needles are used for people who show some difficulty in performing venipuncture. These are:
- Old people
There is the requirement of a shallower angle in the case of the butterfly needles as compared to IV catheters. The reason is that smaller length needles become easier to place on veins, especially for small in size, fragile, or roll.
Butterfly needles are typically used when a person is giving blood to the blood bank. They have a flexible tubing attached to the needle to connect it to the other tubing for collecting blood.
If there is a requirement for IV fluids, the doctor or even nurse will also suggest you use a butterfly needle for getting access to the vein. IV hydration is utilized for treating the problems of dehydration or sometimes when you are unable to eat or drink due to any kind of illness or surgery.
The hollow butterfly needle permits the IV fluids to be infused, which can help in rehydrating you and recover your fluid level.
A butterfly needle permits the doctor to provide IV medication. These medications are pushed with the help of a syringe. Getting those medications through the vein is quite helpful when you can't intake medicine through the mouth or when you want the medication to work faster.
But, keep in mind that butterfly needles are not a proper and long-term solution for IV therapy, medications, or fluids because they will be easily displaced from the vein.
The bottom line is that you can use butterfly needles even when you have a fear of needles because they are very less painful. As they are small in size, so they can easily enter inside the vein. Especially children who have a fear of needles or even adults who don't want to come in contact with needles can use butterfly needles for some specific procedures. Nevertheless, you must be aware that not all of the procedures can be done with these butterfly needles. So, use them carefully!
