Breathing Exercises for Pain and Anxiety During Arteriovenous Fistula Cannulation

Overview

This study aims to evaluate the effects of guided 4-7-8 and diaphragmatic breathing exercises performed during arteriovenous fistula cannulation on pain, anxiety, and comfort levels in patients undergoing hemodialysis treatment. Hemodialysis patients often experience pain and anxiety during fistula cannulation, which can negatively affect the treatment process and patient comfort. The study will be conducted as a three-arm randomized controlled trial. Participants will be randomly assigned to the 4-7-8 breathing exercise group, the diaphragmatic breathing exercise group, or the control group receiving usual care. In the intervention groups, breathing exercises will be performed with guidance before and during cannulation. The study anticipates that breathing exercises will reduce pain and anxiety, increase comfort levels, and contribute as an easily applicable, side-effect-free method to nursing care. The findings are expected to support the use of non-pharmacological interventions in hemodialysis patients.

This study is a randomized controlled trial designed to evaluate the effects of non-pharmacological breathing exercises applied during arteriovenous fistula cannulation on pain, anxiety, and comfort levels in hemodialysis patients. The research will be conducted within routine clinical practice, and no additional invasive procedures will be performed beyond standard care. During the study process, guided breathing exercises will be applied to patients in the intervention groups before and during arteriovenous fistula cannulation, which is routinely performed in the hemodialysis unit. Patients in the control group will continue to receive standard nursing care without any additional intervention. The breathing exercises used in this study are complementary nursing interventions that are easy to apply in clinical settings, cost-free, and associated with no known serious adverse effects. All measurement tools used in the study are validated and reliable instruments, and the collected data will be used solely for research purposes. Participants' personal information will be kept confidential, data will be coded and analyzed anonymously, and no identifying information will be shared with third parties. Participation in the study is entirely voluntary, and participants may withdraw from the study at any time without providing a reason. Withdrawal from the study will not affect patients' ongoing treatment processes or their right to receive healthcare services. The breathing exercises will be administered with careful consideration of patients' physical and cognitive conditions. If any clinical risk or contraindication to the breathing exercises is identified, the intervention will be discontinued immediately. Participant safety will be prioritized throughout the study, and appropriate clinical interventions will be provided promptly in the event of any discomfort or adverse situation. The findings obtained from this study are expected to contribute evidence-based data to nursing care practices related to arteriovenous fistula cannulation in hemodialysis patients and to support the integration of effective non-pharmacological interventions into clinical practice.
