urpose: This study will be carried out to determine the effect of two different catheter covers on the comfort, satisfaction, pain level of the patient and the satisfaction of the nurse.

Materials and Methods: This study, which is planned as an open-label randomized controlled post-test study, will be carried out between December 2021 and February 2022. Data; Descriptive Properties will be collected with the Information Form and Visual Analog Scale (Visual Analog Scale-VAS). Data will be collected face to face by researchers.

Peripheral venous catheter (PVK) is applied to patients who apply to the hospital due to outpatient chemotherapy and need to receive treatment by intravenous route. This application is carried out by nurses. During their education, nurses receive theoretical and practical training on PVC applications. Nurses; They are the primary health professionals who are responsible for determining the PVC site, deciding on the catheter number to be used, applying the correct technique, performing the recommended intravenous (IV) interventions, following the complications that may develop by performing the necessary controls, ensuring the continuity of the application and providing catheter care.

The effective application of interventions such as transfusion of intravenous fluids, chemotherapy drugs, blood and blood products, and total parenteral feeding in cancer patients is provided by PVK. The application of PVC is a necessity for the treatment of the individual receiving treatment and may cause pain, deterioration in comfort and dissatisfaction. Although the widespread use of peripheral venous catheters provides great benefits, it has been reported that undesirable events such as phlebitis, infiltration, obstruction, leakage, and rarely infection occur when applied incorrectly and inadequately. In order for peripheral venous catheters to be used effectively in treatment, it is important to fix them with the correct technique. Detection becomes more important in the use of chemotherapy agents. The patches used for fixation adhere to the glove and are difficult to remove from the patient's skin. Therefore, both the nurse and the patient feel discomfort. For this reason, it would be appropriate to use a material that can be easily torn off with a glove, does not adhere to the glove, and fixes the patient's catheter well. This product should also be able to be easily removed without harming the patient's skin.
