摘要
目的 研究标准化导管维护方案在冠心病监护病房（CCU）患者中心静脉导管相关并发症以及体征、炎症因子指标影响。方法 本次研究采用回顾性分析法，采集本院CCU病房2024年1月-2026年5月收入留置中心静脉导管患者信息，探讨护理期间开展标准化导管维护方案的价值和意义。结果 经标准化导管维护方案干预后，40例CCU患者体温、血氧饱和度、白细胞计数、呼吸频率体征指标显著改善，优于护理前，结果对比有统计学意义（P＜0.05）。护理后患者超敏C‑反应蛋白（hs-CRP）、降钙素原（PCT）、血清淀粉样蛋白A（SAA）炎症因子指标显著降低，结果优于护理前，对比有统计学意义（P＜0.05）。患者中心静脉导管相关并发症发生率为7.50%，护理7d后症状均消失。结论 对CCU患者开展标准化导管维护方案，可缓解静脉导管置管期间炎症刺激，稳定患者生命体征，利于患者康复，可推广。

Abstract
Objective To investigate the effects of standardized catheter maintenance protocol on central venous catheter related complications, signs, and inflammatory cytokine indicators in Coronary Care Unit (CCU) patients. Methods This study used a retrospective analysis method to collect information on central venous catheter patients admitted to the CCU ward of our hospital from January 2024 to May 2026, and explored the value and significance of implementing standardized catheter maintenance plans during nursing. Results After intervention with a standardized catheter maintenance plan, 40 CCU patients showed significant improvements in body temperature, blood oxygen saturation, white blood cell count, and respiratory rate signs, which were better than before nursing. The comparison of results was statistically significant (P<0.05). After nursing, the inflammatory factor indicators of high‑sensitivity C‑reactive protein (hs CRP), Procalcitonin (PCT), and Serum Amyloid A (SAA) in patients were significantly reduced, and the results were better than before nursing, with statistical significance (P<0.05). The incidence of complications related to central venous catheterization in patients was 7.50%, and the symptoms disappeared after 7 days of nursing care. Conclusion Implementing a standardized catheter maintenance plan for CCU patients can alleviate inflammatory stimulation during venous catheter placement, stabilize patient vital signs, facilitate patient recovery, and can be promoted.
