ABSTRACT: Objective: To investigate the application of the sitting puncture technique for modified midline catheter (MMC) insertion in patients with acute exacerbation of chronic heart failure (AECHF), aiming to improve puncture success rate and patient comfort, thereby providing clinical evidence for patients who cannot lie flat due to disease but urgently require venous access. Methods: A retrospective analysis was conducted on 18 AECHF patients in our department from January 2022 to April 2025 who underwent MMC insertion using the sitting puncture technique due to intolerance to supine positioning. The key nursing considerations and experiences throughout the procedure were summarized. Results: Among the 18 patients, one procedure was discontinued due to poor vascular condition and worsening heart failure symptoms. The remaining 17 patients were successfully implanted with MMCs. All catheter tips were positioned in the subclavian vein, with indwelling durations ranging from 7 to 20 days, and no complications occurred. Conclusion: The application of the sitting puncture technique for MMC insertion in AECHF patients is feasible. It improves the success rate of catheterization and enhances patient comfort, leading to increased patient satisfaction and compliance with intravenous therapy, without increasing the incidence of adverse reactions.
