摘　　要：目的探讨生理盐水持续加压冲洗管路对维持有创血压管道通畅性的效果。方法前瞻性分析117例行有创动脉血压监测患者，按收治顺序随机分为试验组59例和对照组58例；试验组使用生理盐水持续加压冲洗，对照组使用25U／mL稀释肝素钠溶液持续加压冲洗，比较两组4d内动脉置管堵管率、动脉炎、穿刺部位出血及肝素诱导的血小板减少症的发生率。结果试验组动脉置管堵塞7例（堵管率11．9％），对照组动脉置管堵塞6例（堵管率10．3％）；两组比较差异无统计学意义（P〉0．05）。试验组未发生动脉炎、穿刺部位出血及肝素诱导的血小板减少症（HTC）；对照组发生动脉炎3例（发生率5．1％），穿刺部位出血8例（发生率13．8％），肝素诱导的血小板减少症2例（发生率3．4％）；两组比较差异均有统计学意义（P〈0．05）。结论生理盐水持续加压冲洗管路，能有效地维持有创血压管道的通畅，减少并发症的发生，值得临床推广。Objective To study the effect of continuous normal saline pressed flush on patency of invasive blood pressure pipeline. Methods 117 cases of patients needing invasive artery pressure monitoring were prospectively analyzed, which were allocated to experimental group （ n = 59 ） and control group （n = 58 ） arranged by registration order. Patients in experimental group receive normal saline pressed flush and patients in control group receive diluted heparinized saline flush （25 U/mL）. The rate of arteritis, heparin injection site bruising and heparin - induced thrombocytopenia were compared between the groups. Results The blocking rate was 11.9% in experimental group and 10. 3% in control group. There was no significant difference between the two groups （ P 〉 0.05 ）. There were no arteritis and injection site bruising and heparin -induced thrombocytopenia in experimental group. Among the control group, the rate of arteritis and heparin injection site bruising and heparin - induced thrombocytopenia were 5.1%, 13.8% and 3.4%, respectively; the difference between two groups was significant （P 〈0.05 ）. Conchltsion Continuous normal saline pressed flush can keep the patency of invasive blood pressure pipeline effectively and reduce complications; therefore it has great value in clinical application.
