藻酸盐敷料预防早产儿PICC穿刺点渗血和炎性反应的效果观察

Effect of Alginate Dressings on Reducing PICC Insertion Sites Infection in Preterm Infants

目的探讨藻酸盐敷料在早产儿PICC中预防置管后穿刺部位渗血和穿刺点炎性反应的效果。方法将79例符合PICC置管条件的早产儿分为观察组(31例)和对照组(48例),观察组在穿刺成功后,用2.5 cm×5.0 cm藻酸盐敷料3折后覆盖穿刺点,用3M敷贴固定,48 h更换0.5 cm×0.5 cm藻酸盐敷料,并用3M敷贴固定,7 d后换药;对照组用无菌纱布覆盖穿刺点,其余方法均同观察组。分别在48 h、7 d查看敷料有无出血及穿刺点的炎性反应。结果观察组穿刺点渗血发生率明显少于对照组(P<0.01);观察组炎性反应发生率也少于对照组(P<0.05)。结论早产儿PICC穿刺成功后用藻酸盐敷料覆盖穿刺点,能有效预防PICC置管后的穿刺点渗血及炎性反应。

Objective To observe the effect of alginate dressings on reducing the peripherally inserted central catheter （PICC） insertion sites infection in preterm infants. Methods Total 79 preterm infants meet PICC condition were divided into the observation group（ 31 cases） and control group（48 cases）. In the observation group, 2.5 cm×5.0 cm alginate dressings which folding 3 times was used to cover the insertion sites and fixed with 3M dressing,and the alginate dressings was replaced by 0.5 cm x 0.5 cm alginate dressings 48 h later;the dressings was changed 7 days later. In the control group, instead of alginate dress- ings,the sterile gauze of was used to cover the insertion sites. At 48 h,7 days,the insertion sites infection or bleeding was recor- ded. Results The incidence of insertion sites bleeding in the observation group was lower than that in the control group, and the differences was statistically significant（ P 〈 0.01 ） ;while the incidence of insertion sites inflammation in the observation group is lower than that in the control group, the differences was statistically significant （ P 〈 0.05 ）. Conclusion The alginate dressings can effectively reduce PICC insertion sites bleeding and infection in preterm infants.
