Fear Needles

Purpose: The purpose of this study is to evaluate the effectiveness of a "Palm Stimulator" (a handheld device with blunt protrusions) in reducing pain, fear, and anxiety during peripheral venous catheterization (IV insertion) in adult cancer patients receiving chemotherapy. Methods: This is a randomized controlled clinical trial. Participants will be randomly assigned to either the Experimental Group or the Control Group. Experimental Group: During the IV insertion process, patients will hold and squeeze the Palm Stimulator in the palm of their non-procedural hand. The device is designed to provide intense tactile (touch) stimulation based on the "Gate Control Theory." Control Group: Patients will receive the standard routine care for IV insertion without any additional intervention. Data Collection: Pain intensity will be measured using the Visual Analog Scale (VAS), while fear and anxiety levels will be assessed through VAS scales before and after the procedure. Patient satisfaction with the device will also be recorded. Expected Outcome: The investigators hypothesize that the use of the Palm Stimulator will significantly decrease procedural pain and fear while increasing patient satisfaction compared to standard care. This study aims to provide a low-cost, non-pharmacological, and easy-to-use tool for oncology nurses to improve patient comfort during invasive procedures.

This research will be conducted in a pre-test-post-test parallel group randomized controlled experimental study model to determine the effects of rain stick and musical egg applied during blood collection on pain, fear and anxiety in children aged 4-6. Research Hypotheses H1: The mean pain scores of the children in the rain stick group are lower than the mean scores of the children in the control group. H2: The mean fear scores of the children in the rain stick group are lower than the mean scores of the children in the control group. H3: The mean anxiety scores of the children in the rain stick group are lower than the mean scores of the children in the control group. H4: The mean pain scores of the children in the musical egg group are lower than the mean scores of the children in the control group. H5: The mean fear scores of the children in the musical egg group are lower than the mean scores of the children in the control group. H6: The mean anxiety scores of the children in the musical egg group are lower than the mean scores of the children in the control group.
