Write the difference between a Cannula and needles.

When it comes to the medical industry, both needles and stainless steel cannula play a vital role. Both of them serve the same functions like drawing blood from patients, injecting medicine, and cosmetic procedures, but still, there is a major difference between them that can impact the outcomes of the treatment. So, understanding the difference between the two and making the right choice will lead to better results and patient safety.

Key Differences Between Cannula and Needles 

The selection between the two is not about choice but it depends on specific factors like the amount of depth required for the injection, and the desired outcome among others. While some practitioners may choose one over the other it is vital to understand the difference between the two to make a wise decision.

Sharpness:

The needle consists of a sharp, pointed design that penetrates the skin and the underlying tissue. It allows precise delivery of the medication in the desired area of the skin.

The cannula on the other hand has a round tip, which does not tear into the skin. The cannula pushes them aside. They are ideal for sensitive areas and soft filler treatment. Most of the patients prefer getting injected with a cannula because it reduces the pain and fear of sharp needles.

Flexibility:

The needles are small, however, they offer great precision for treatments like Botox where precise control of fluid is necessary. The cannulas are longer and more flexible and cover more area with a single injection point. They can also be integrated with other medical devices like medical tubing and syringes. However, the stainless steel cannula needs an expert to accurately administer the filler in certain areas.

Complications & Precautions:

The sharp tip of the needle if not handled with care can lead to the puncturing of the blood vessels. There is also a risk of needlestick injuries if the pointy end punctures the needles after the procedure. 

The chances of injuries with a cannula are less, thanks to its blunt tip, they are less likely to damage the blood vessels. Also, you can be secure from accidental punctures.

Substance to be Injected:

The difference also largely depends on the kind of fluid that will be injected inside. The needles are well-suited for injecting viscous liquids like thick dermal fillers, as it is used to restore volume in the sunken area.

The cannula is used for thinner fillers or intravenous cannulation in hospitals and IV infusion clinics.

Final Words…

The choice between the needles and the cannula depends on the specific treatment and also the patient’s preferred technique.  An experienced healthcare professional should be able to offer both methods, explaining the benefits as well as side- effects of each.
