CSTD Features To Minimize Exposure Risks


The administration of hazardous and dangerous oncology medications has long been an issue for nurses and other healthcare providers. Simply put, constant exposure to these medications is a health risk that can lead to organ failure and other health issues. This is why containment or CSTD systems are utilized when the drugs are administered to patients. The systems may use a variety of different precautions to ensure that you are not exposed. Keep reading to learn about a few common ones.

Syringe Locking 

Most CSTD systems use syringes, reservoirs, and vials that are connected to IVs and other devices so that medications can be administered. And, the reservoir and the IV must be connected in order for the patient to receive their medication. This involves the engagement of the CSTD parts and once engagement occurs, only then will the medication become available. 

Engagement of devices involves safety locks and other systems that keep exposure to a minimum. The feature is often called a syringe or system lock device and you will be unable to open the machinery once engagement occurs. 

There are a few different options when it comes to the safety feature. Some devices are actually fused together so they cannot be taken apart while others break free from the turning mechanism once engaged. Some devices even have one-way spinning pieces that cannot be turned in the opposite direction. 

You should know that once the mechanism is locked in place, it can no longer be accessed in an easy manner. So, you will have to implement a multiple check system to make sure that medications errors do not occur of the entirety of the CSTD system and medication will need to be thrown out if a mistake is made.

Vial Spikes

Sometimes vials are used instead of bags or container of medication. This can present some problems because vapor can be released once the needle or spike hits the top of the vial. Vapor can release medication that may be inhaled or splashed on the body. 

Vapor issues are reduced with the use of pathway or vial spiking systems. The systems are either membrane to membrane or needle insertion cones or pathways.

Both these systems provide an enclosed space that is locked into place. Membranes are placed together with a small space in between. This allows for a needle to puncture the membrane and vapor can release into the open area. Needle insertion devices keep the needle pathway completely enclosed so that vapor release is not possible. These sorts of insertions do require pressure equalization, so make sure the system is built with this in mind.
