Music-Assisted Acupressure for Pain During AVF Cannulation in Hemodialysis Patients

This randomized controlled trial was conducted to evaluate the effect of music-assisted acupressure on pain experienced during arteriovenous fistula (AVF) cannulation in hemodialysis patients. The study was carried out with 72 patients receiving hemodialysis treatment three times per week via AVF in a state hospital in Gaziantep, Türkiye. Participants were randomly assigned to one of four groups: music-assisted acupressure, acupressure alone, music alone, and control group (routine care). The acupressure intervention was applied to the Hegu (LI4) point for approximately 3 minutes prior to needle insertion, while the music intervention consisted of listening to instrumental Classical Turkish Music in the Acemaşiran mode through headphones starting 5 minutes before cannulation and continuing until the end of the procedure. Pain intensity during AVF cannulation was measured using the Visual Analog Scale (VAS) during three consecutive dialysis sessions. The primary outcome was pain severity during needle insertion. The study aimed to determine whether combining music therapy and acupressure would provide greater pain relief compared to single interventions or routine care. Findings suggest that music-assisted acupressure may be an effective non-pharmacological nursing intervention for reducing procedural pain in hemodialysis patients.

Single-Needle Distal Return for Long-Term Arteriovenous Fistula Care

Background: For millions of people worldwide with kidney failure, a well-functioning vascular access, like an arteriovenous fistula (AVF), is essential for life-sustaining hemodialysis. However, the standard method requires puncturing the same AVF with two needles three times a week, which over time can damage the vessel, leading to scarring, narrowing, and frequent failures. These complications often require repeated surgical or minimally invasive procedures (reinterventions), causing significant pain, high medical costs, and exhaustion of the patient's limited blood vessels. New Approach: This study will evaluate a modified puncture technique called the Single-Needle Distal Return (SNDR) strategy for long-term AVF care. Instead of using two needles in the AVF, only one needle is placed in the AVF to draw blood. The cleaned blood is then returned to the body through a second needle placed in a superficial vein in the foot or lower leg. This approach aims to reduce trauma to the critical AVF. Study Plan: This is a clinical study conducted at the Blood Purification Center of Anhui Medical University Affiliated Suzhou Hospital. We plan to enroll approximately 50 adult hemodialysis patients who use an AVF and are willing to try the SNDR technique. For comparison, we will also observe data from a similar number of patients receiving standard two-needle AVF care during the same period. The study will last about three years. We will closely monitor patients using the SNDR technique to assess: Effectiveness: Whether dialysis remains adequate (measured by Kt/V). Safety: Rates of complications (like bruising or infection), dialysis machine alarms, and venous pressure during treatment. Practical Benefits: Whether it reduces the need for repair procedures (reinterventions) and hospitalizations related to the AVF. Economic Impact: Changes in healthcare costs. Patient Experience: Patient tolerance and comfort with the technique. We will also analyze the characteristics of patients who successfully use this technique long-term to help identify who might benefit most from it in the future. Potential Significance: If proven successful and safe for long-term use, the SNDR strategy could help protect a patient's precious AVF, potentially reducing painful procedures, lowering costs, slowing down the exhaustion of blood vessels, and improving the quality of life for people on long-term dialysis. The findings may also guide better planning for vascular access care.
