银离子藻酸盐抗菌敷料用于血液病患者PICC置管的效果观察

Effect of alginate dressing with silver on PICC catheter in agranulocytosis patients

目的：观察银离子藻酸盐抗菌敷料（银离子敷料）用于血液病患者PICC置管穿刺点的临床效果。方法将76例PICC术后患者随机分为观察组39例和对照组37例，观察组采用银离子敷料置于穿刺点，对照组采用无菌纱布置于穿刺点。比较两组患者穿刺点处切口感染发生率、穿刺点处切口愈合前换药次数及加压时间。结果观察组加压时间为（2．77±1．27）d，无红肿热痛患者，PICC全部保留；对照组患者加压时间为（4．51±1．41）d，有1例患者发生红肿热痛症状，PICC全部保留，两组患者加压时间比较，差异有统计学意义（t＝-5．687，P＜0．05）。观察组换药次数为（2．74±0．99）次，对照组换药次数为（4．73±1．41）次，两组比较差异有统计学意义（ t＝-7．140，P＜0．05）。结论使用银离子敷料可以减少血液病患者行PICC置管术后穿刺点处切口愈合前换药次数和加压时间，加速切口愈合。

Objective To observe the clinical effect of alginate dressing with silver （ sliver ions dressing） on puncture site of PICC catheter in agranulocytosis patients .Methods Seventy-six cases of agranulocytosis patients after PICC were randomly divided into the observation group （ n=39 ） and the control group （n=37）.The observation group received alginate dressing with silver on puncture site , while the control group was given sterile gauze on puncture site .Infection incidence , times of dressing change and pressure days were compared between two groups .Results The pressure days in the observation group was （2.77 ±1.27）d and there was no cases of swell or pain .The pressure days was （4.51 ±1.41）d and there was one case of swell and pain in the control group .The difference of pressure days was statistically significant （ t=-5.687,P〈0.05）.The times of dressing change was （2.74 ±0.99） in the observation group and （4.73 ±1.41） in the control group, with a statistically significant difference （t =-7.140,P 〈0.05）.Conclusions Alginate dressing with silver on puncture site of PICC catheter for agranulocytosis patients can reduce the time of dressing change and pressure days , and accelerate their healing .
