Abstract
BACKGROUND: Peripherally inserted central catheters (PICCs) are crucial for patients requiring long-term intravenous therapy, especially within digestive surgery under bundled care protocols. AIM: To evaluate and compare the efficacy, safety, and patient-reported outcomes of single-lumen vs double-lumen PICCs among patients undergoing digestive surgery within a structured bundled care framework. METHODS: This retrospective cohort study analyzed data from 249 patients who underwent digestive surgery and utilized either single-lumen (n = 117) or double-lumen (n = 132) PICCs between January 2021 and June 2024. Clinical outcomes, patient satisfaction, catheterization duration, and complication rates were compared using statistical analysis via SPSS (version 29.0). The bundled care protocol was consistently applied, focusing on standardized procedures, staff training, and patient support. RESULTS: Single-lumen PICCs were associated with a significantly lower thrombosis rate (0.85%) than double-lumen PICCs (6.82%, P = 0.039). The single-lumen group experienced shorter catheterization durations (12.5 ± 3.14 days vs 13.6 ± 4.50 days, P = 0.025) and higher successful infusion rates (92.7% ± 5.32% vs 90.4% ± 6.60%, P = 0.003). This group also reported higher comfort scores (8.40 ± 1.20 vs 7.90 ± 1.50, P = 0.004) and lower pain levels (2.90 ± 0.70 vs 3.20 ± 0.80, P = 0.002). Aside from thrombosis, complication rates showed no significant difference between the groups. CONCLUSION: Within bundled care context, single-lumen PICCs demonstrated advantages in reducing thrombosis risk, procedural efficiency, patient comfort, and satisfaction compared with double-lumen PICCs. The findings underscore the importance of considering patient-specific needs and clinical scenarios in catheter choice.
