Abstract titles should be brief and reflect the content of the abstract.
The arteriovenous fistula (AVF) is the preferred vascular access for patients undergoing maintenance hemodialysis, featuring advantages such as low infection risk, long service life, and stable blood flow. However, during long-term hemodialysis treatment, repeated puncture of the arteriovenous fistula has become one of the main sources of physical and psychological distress for patients. Clinical observations indicate that nearly 80% of hemodialysis patients experience moderate to severe pain during arteriovenous fistula puncture; this pain not only causes immediate discomfort (e.g., local stabbing pain, muscle tension) but also leads to long-term adverse consequences. For instance, patients may develop puncture-related anxiety, refuse regular treatment, or even reduce their compliance with vascular access care, thereby increasing the risk of complications such as fistula hematoma and thrombosis. Against this backdrop, optimizing puncture nursing protocols to alleviate patients' pain has become a key focus in clinical hemodialysis nursing practice.
A self - before - and - after control design was adopted. A total of 60 patients with arteriovenous fistula who met the inclusion and exclusion criteria in a hemodialysis center from January 2025 to June 2025 were selected as the research objects. The control group (January to March 2025) received routine arteriovenous fistula puncture nursing, while the experimental group (April to June 2025) adopted the painless nursing management model, which specifically included the following aspects:
1. Nursing staff training: A special painless nursing team (5 members with more than 5 years of work experience) was established in the center. Before the implementation of the project, a 1 - week special training was uniformly conducted. The training contents included overview of pain, arteriovenous fistula puncture skills, communication skills, and puncture demonstration on arm models. Only those who passed the assessment could participate in the subsequent operations.
2. Pain assessment: The Visual Analogue Scale (VAS) was used to dynamically assess the patients' pain degree before, during and after puncture. A personalized pain file was established based on the patients' subjective experience, and the nursing plan was adjusted in a timely manner according to the scores.
3. Pain intervention:
◦ Reducing pain threshold: During the operation, the nurses talked with the patients about daily life or played light music that the patients liked to divert their attention. The temperature of the hemodialysis hall was maintained at 20 - 24℃ to reduce the stimulation of strong light and noise. The patients were advised not to be on an empty stomach before puncture. Before puncture, a warm towel at 40 - 42℃ was used to apply hot compress to the puncture site for 5 - 10 minutes, and muscle relaxation training was conducted. The use time of the tourniquet during puncture did not exceed 30 seconds.
◦ Reducing tissue damage: After the disinfectant was completely dry, the "C" - shaped method was used to fix the blood vessel. The skin was stretched tightly during puncture. The needle insertion angle was adjusted to 30 - 45° according to the condition of the blood vessel.
◦ Alleviating local stimulation: 30 minutes before puncture, the patients were instructed to use lidocaine aerosol spray on the puncture site. The needle shaft of the puncture needle was lubricated in advance with normal saline. The "fast needle insertion - slow pushing" technique was adopted. After puncture, 2mm of the needle shaft was exposed and properly fixed.
Finally, the VAS score, one - time puncture success rate, incidence of arteriovenous fistula complications (such as hematoma and infection) and nursing satisfaction of the patients before and after the intervention were compared.
After the intervention, the VAS score of the patients [(2.15 ± 0.62) points] was significantly lower than that before the intervention [(5.32 ± 1.08) points], and the difference was statistically significant (t = 21.36, P < 0.01). The one - time puncture success rate [96.67% (58/60)] was higher than that before the intervention [81.67% (49/60)], and the difference was statistically significant (χ² = 6.99, P < 0.01). The incidence of fistula complications [8.33% (5/60)] was lower than that before the intervention [15.00% (9/60)], but the difference between the two groups was not statistically significant (χ² = 1.29, P = 0.26). The nursing satisfaction [95.00% (57/60)] was higher than that before the intervention [78.33% (47/60)], and the difference was statistically significant (χ² = 7.21, P < 0.01).
Through systematic staff training, accurate pain assessment and multi - dimensional intervention, the painless nursing management model can effectively reduce the puncture pain of arteriovenous fistula in hemodialysis patients, improve the puncture quality and patient satisfaction, and at the same time, it does not increase the incidence of arteriovenous fistula complications. It is of great significance for improving the quality of life of patients and is worthy of clinical promotion.
