藻酸盐银联合透明贴预防肺癌PICC导管穿刺部位局部感染的观察

Effect observation of alginate silver combined with transparent dressing on prevention of local infection of PICC puncture site in patients with pulmonary carcinoma

目的探讨早期应用藻酸盐银联合透明贴预防肺癌经外周静脉穿刺中心静脉导管(PICC)穿刺部位局部感染的疗效。方法将80例肺癌PICC患者随机分成观察组和对照组各40例,对照组穿刺置管后给予常规穿刺点小纱布覆盖,外用3M透明贴膜固定,观察组则用藻酸盐银覆盖穿刺点,外用透明贴固定,比较2组穿刺部位局部感染率。结果 7 d后观察组未发生1例穿刺部位感染,有效率100%;对照组发生4例,其中3例患者穿刺部位周围红、肿、疼痛,范围约3 cm,1例周围红肿约4 cm并发穿刺点破溃,有少许渗液为脓性分泌物,4例患者均无全身症状且在改用藻酸盐银敷料后均好转治愈。结论藻酸盐银联合透明贴预防和治疗PICC导管穿刺部位局部感染疗效显著,值得在临床应用推广。

Objective To explore the effect of alginate silver combined with transparent dressing on prevention of local infection of PICC puncture site in patients with pulmonary carcinoma.Methods 80 pulmonary carcinoma patients with PICC were randomly divided into observation group（n=40） and control group（n=40）.Puncture sites in the control group were covered with small gauze after puncture and catheterization,and then were fixed with 3M transparent dressing;the puncture sites in the observation group was covered with alginate silver,and then were fixed with transparent dressing.Rate of infection in the local puncture site were compared between two groups.Results 7 days after treatment,no patients had infection in the puncture site in the observation group,the effective rate was 100%;in the control group,4 patients had infections,including 3 cases of red,pain and swelling sensation in the peripheral position of puncture site（range of 3 cm in diameter） and one case of red,swelling and abscess rupture in peripheral position of puncture site（diameter of about 4 cm）.All of 4 patients had no systemic symptoms,and their symptoms were improved after use of alginate silver.Conclusion Efficacy of early application of alginate silver combined with transparent dressing on prevention of local infection of PICC puncture sites is significant,so it is worthy of clinical application and popularization.
