The Effect of ShotBlocker on Pain, Anxiety, and Satisfaction During Peripheral Intravenous Catheterization

Overview

This randomized controlled trial aims to evaluate the effect of the ShotBlocker device on pain, anxiety, and patient satisfaction during peripheral intravenous catheterization (PIVC). Peripheral intravenous catheterization is a commonly performed procedure in clinical settings and is often associated with pain and anxiety, which may negatively affect patient experience. The ShotBlocker is a simple, non-pharmacological device designed to reduce pain by applying pressure and sensory stimulation at the injection site. Participants will be randomly assigned to either the intervention group, where the ShotBlocker will be used during the procedure, or the control group, where routine care will be provided.Pain will be assessed using the Visual Analog Scale (VAS). Anxiety and patient satisfaction will be evaluated using a visual analog-based scale supported , combining features of the Visual Analog Scale and the Wong-Baker Faces Scale, with scores ranging from 0 to 10. The findings of this study are expected to contribute to evidence-based nursing practices by providing an effective, low-cost, and non-invasive method for reducing procedural discomfort and improving patient experience during PIVC.

Peripheral intravenous catheterization (PIVC) is one of the most frequently performed invasive procedures in clinical practice. Despite its routine nature, it is commonly associated with pain and anxiety, which may negatively influence patient comfort, satisfaction, and overall experience of care. Therefore, effective and practical strategies to reduce procedure-related discomfort are essential in nursing practice. The ShotBlocker is a simple, non-pharmacological device designed to reduce pain by applying mechanical pressure and providing sensory distraction at the injection site. It is inexpensive, easy to use, and does not require additional training or pharmacological intervention, making it suitable for routine clinical use. This study is designed as a randomized controlled trial to evaluate the effectiveness of the ShotBlocker device during PIVC. Participants will be randomly assigned to either the intervention group, in which the ShotBlocker will be applied during the catheterization procedure, or the control group, in which routine care will be provided without any additional intervention. Pain intensity will be assessed using the Visual Analog Scale (VAS). Anxiety and patient satisfaction will be evaluated using a visual analog-based scale supported by combining features of the Visual Analog Scale and the Wong-Baker Faces Scale, with scores ranging from 0 to 10. All procedures will be performed by trained healthcare professionals following standard clinical protocols. Data will be collected immediately after the procedure. The primary outcome of the study is pain intensity, while secondary outcomes include anxiety and patient satisfaction. The results of this study are expected to provide evidence for the effectiveness of a simple, non-invasive, and cost-effective method to reduce procedure-related discomfort and improve patient-centered care in clinical settings.
