Peripheral venous access is one of the most commonly used methods of administration in hospital settings. It offers several advantages, including relatively simple and rapid placement, as well as good tolerance among most patients. It is primarily used to administer medications that require venous access, such as antibiotics, analgesics, or intravenous chemotherapy treatments.

The placement of a peripheral venous access is done using a needle or a short catheter introduced into a superficial vein, usually at the level of the arm or hand. Once the catheter is correctly positioned, a securing device is used to keep the catheter in place. There are different types of peripheral catheters depending on their gauge and length.

- Administration of medications: peripheral venous access allows for the direct and rapid administration of medications into the bloodstream, which is particularly important in emergencies or when the patient cannot take medications orally.

- Administration of infusion fluids: in cases of dehydration, blood loss, or nutritional needs, peripheral venous access allows for the administration of fluids directly into the bloodstream to restore the patient's fluid balance.

- Blood draw: blood samples can be taken from a peripheral venous access, which avoids the need for repeated needle sticks.

Although peripheral venous access is generally well tolerated, it is important to take certain precautions during its placement and use. Here are some tips:

- Follow aseptic rules: rigorous disinfection of the skin is necessary before placing the catheter to reduce the risk of infection.

- Choose the appropriate size: depending on the duration of treatment and the characteristics of the patient, it is important to choose a catheter of the appropriate size to avoid complications related to inadequate venous access.

- Regularly check the condition of the catheter: it is necessary to ensure that the catheter is functional, with no signs of inflammation or infection, and to replace it if necessary.

Possible complications related to peripheral venous access include infiltration (leakage of the administered solution into surrounding tissues), air embolism, infection at the insertion site, venous thrombosis, etc. These complications can be prevented or detected early by adhering to good care practices and closely monitoring the patient.
