地塞米松肝素盐水预防PICC静脉炎的临床研究

Clinical research of dexamethasone and heparin saline in prevention of PICC phlebitis

目的探讨单腔三向瓣膜式PICC导管经地塞米松肝素盐水浸泡后再置管,对静脉炎发生的影响。方法将120例需置管的患者,随机分为实验组和对照组各60例,实验组采用地塞米松肝素盐水将PICC导管完全浸泡,对照组采用无菌生理盐水将PICC导管完全浸泡,分别观察2组患者静脉炎发生情况。结果实验组静脉炎发生率为3.34%,对照组静脉炎发生率为18.33%,两组例数经统计学分析,差异有统计学意义(P<0.05)。结论经地塞米松肝素盐水浸泡后的PICC导管置管后静脉炎的发生率明显下降,延长了导管的留置时间,减少了患者的痛苦,降低了医疗费用,提高了患者的满意度及生存质量。

Objective To explore the influence of dipping tri- valve peripherally inserted central catheter （PICC） tube in dexamethasone and heparin saline on the incidence of phlebitis. Methods A total of 120 patients who needed intubation were randomly divided into study group （n = 60） and control group （n = 60）. PICC tubes of the study group were dipped into dexametha- sone and heparin saline, while PICC tubes of the control group were only dipped into physiological saline. The incidence rates of phlebitis in the two groups were observed. Results The incidence rate of phlebitis of the study group was 3.34%, while it was 18.33% in the control group. The difference was statistically significant （P ~ 0.05）. Conclusion PICC tubes dipping in dexametha- sone and heparin saline can decrease the incidence rate of phlebitis, prolong the indwelling duration, reduce the pains and cost of patients, and raise the satisfactoriness and survival quality of patients.
