Research on comprehensive analysis of patient comfort and complication rate using haemodialysis indwelling needles in AVF puncture in haemodialysis treatment

Abstract

Traditional needles for haemodialysis access can cause complications and discomfort. Indwelling needles may have advantages, but their efficacy needs to be investigated. Our study sought to compare the safety and efficacy of indwelling needles to traditional needles for haemodialysis access. A single-center retrospective study at the Pingyang County Hospital of Traditional Chinese Medicine included 70 haemodialysis patients. The intervention group used indwelling needles, whereas the control group used traditional needles. The rate of complications, limb mobility, blood chemistry, puncture success rates, operation times, haemostasis times, pain and comfort scores, and internal fistula failure rates were all compared. Overall, complication rates were slightly higher in the control group, but not statistically significant. Both groups improved their limb mobility and blood chemistry, but there were no significant differences. The intervention group had significantly higher puncture success rates (88.4% vs. 80.0%), shorter operation times (65.4 vs. 72.3 seconds), and faster haemostasis times (23.7 vs. 28.2 seconds) than the control group. Patients in the intervention group experienced less pain (3.7 vs. 4.2) and more comfort (8.1 vs. 7.5). The intervention group had slightly lower internal fistula failure rates (2.9% vs. 5.7%), but the difference was not statistically significant. Indwelling needles appear to improve puncture efficiency and patient comfort during hemodialysis.
