Peripheral punctures

Cannulation is one of the most commonly performed procedures in hospitals and other medical facilities, involving the insertion of a cannula into a vein for the purpose of administering medication, fluids, or obtaining blood samples. It is important to note that safe infusion requires proper preparation and disinfection of the insertion site, as well as the use of single-use equipment. Although widely used, it can be associated with complications such as infections, thrombosis, or vein inflammation. Therefore, the selection of an appropriate vascular access and visual monitoring of the insertion site are crucial. To minimize the risk of complications, the dressing at the insertion site should be regularly checked and changed. Short peripheral cannulas remain the most popular choice, varying in size, design, and insertion technique, with a lifespan typically not exceeding a few days. Maintaining cannula patency often requires the use of saline solution. Cannulation of peripheral veins is critical in many medical procedures, including emergency situations.

In the case of a patient for whom therapy longer than 6 days is anticipated, or who has been classified as a "difficult venous access patient," intermediate-length cannulations, such as mini-midline cannulation, should be considered. To minimize the risk of complications, it is advisable to choose cannulas without an upper port, which align with current global trends in infusion therapy.
