An intravenous (I.V.) cannula is an indispensable medical device in modern healthcare settings, extending its utility from emergency rooms to operation theatres. It serves as a lifeline for immediate access to a patient’s circulatory system.
Since its invention in 1845 by Francis Rynd, I.V. cannulas have undergone significant changes in their shape and design. Initially, these tools were rigid and featured large-bore stainless steel or silver needles, causing discomfort and necessitating the shared use of syringes among multiple patients.
Over the next few decades, the design of I.V. cannulas underwent radical transformations. Thorough improvements were made in their operation, usage, and disposal techniques, giving rise to the modern version of I.V. cannulas, which can be segregated into two variants: Disposable and Non-Disposable.
Here, we will discuss what sets these two variants apart.
Disposable I.V. Cannulas
Disposable I.V. cannulas offer the utmost assurance in terms of sterility and hygiene. The present-day generation of healthcare workers actively use and promote disposable I.V. cannulas. They come in sterilized packing and are ready for immediate use, minimising the risk of cross-contamination and infections. Designed for one-time usage, these cannulas must be disposed of immediately after use. The only downside is that the disposal of single-use cannulas contributes to an increased amount of pharmaceutical waste.
Non-Disposable I.V. Cannulas
As the name suggests, non-disposable I.V. cannulas are cleaned and reinsert or can be reused multiple times. After each treatment, these devices demand an extensive sterilisation process to minimise the risk of cross-contamination. Opting for non-disposable I.V. cannulas is often motivated by both economic and environmental standpoints.
With multiple uses, these cannulas help reduce waste generation and long-term costs. However, their usage is bundled with challenges. Healthcare professionals must take stern measures to ensure effective sterilisation and storage. Additionally, constant monitoring for wear and tear is also advised.
Why are Disposable I.V. Cannulas better than Non Disposable I.V. Cannulas?
The disposable I.V. Cannulas has lot of advantages over a non-disposable I.V cannulas, like
• Rapid reliable blood flash back chambers through notch needles
• More closed to bacterial entry, hence, Lowering the risk of infection and thrombosis.
• Minimal blood exposure to the users
• No sterilisation is needed after every use because disposable is available in sterilised packaging.
The debate within medical societies regarding the selection of disposable versus non-disposable I.V. cannulas has been ongoing. However, the widespread use of disposable I.V. cannulas has significantly improved sanitation and hygiene, making them a convenient and safer choice.
