The use of antibacterial agents to clean and dry the stump of the newborn's umbilical cord after birth has recently been abandoned by many neonatal units in favor of dry cord care. The objective of this study was to compare cord bacterial colonization and morbidity among newborns whose cords were treated with triple dye and alcohol versus dry cord care.
We randomly allocated 766 newborns to either 2 applications of triple dye to the umbilical cord stump on the day of birth with alcohol swabbing twice daily until the cord fell off (n = 384) or dry care (n = 382). Dry care consisted of spot cleaning soiled skin in the periumbilical area with soap and water, wiping it with a dry cotton swab or cloth, and allowing the area to air dry. Umbilical stumps on all subjects were swabbed and cultured. Community health nurses visiting at 2 or 3 days after hospital discharge observed the stump for signs of infection. Follow-up phone calls were made to mothers within 3 weeks of discharge.
One infant in the dry care group was diagnosed with omphalitis. The umbilical stump was colonized with alpha-hemolytic streptococcus and coagulase-negative staphylococcus. Infants in the dry care group were significantly more likely to be colonized with Escherichia coli (34.2% vs 22.1%), coagulase-negative staphylococci (69.5% vs 50.5%), Staphylococcus aureus (31.3% vs 2.8%), and group B streptococci (11.7% vs 6.0%). Community health nurses were significantly more likely to observe exudate (7.4% vs 0.3%) and foul odor (2.9% vs 0.7%) among infants allocated to the dry care group during the home visit.
Omphalitis remains a clinical issue. Cessation of bacteriocidal care of the umbilical stump must be accompanied by vigilant attention to the signs and symptoms of omphalitis.
近期许多新生儿病房已摒弃使用抗菌剂清洁和干燥新生儿出生后的脐带残端,转而采用脐带干燥护理。本研究的目的是比较脐带经三联染料和酒精处理的新生儿与接受脐带干燥护理的新生儿的脐带细菌定植情况及发病率。
我们将766名新生儿随机分为两组,一组在出生当天对脐带残端进行两次三联染料涂抹,并每日用酒精擦拭两次,直至脐带脱落(n = 384);另一组采用干燥护理(n = 382)。干燥护理包括用肥皂和水局部清洁脐周区域的脏污皮肤,用干棉签或布擦拭,然后让该区域自然风干。对所有受试者的脐带残端进行擦拭和培养。出院后2或3天进行家访的社区健康护士观察脐带残端有无感染迹象。出院后3周内对母亲进行随访电话。
干燥护理组有1名婴儿被诊断为脐炎。脐带残端定植有α-溶血性链球菌和凝固酶阴性葡萄球菌。干燥护理组的婴儿更易定植大肠杆菌(34.2%对22.1%)、凝固酶阴性葡萄球菌(69.5%对50.5%)、金黄色葡萄球菌(31.3%对2.8%)和B组链球菌(11.7%对6.0%)。在家庭访视期间,社区健康护士在接受干燥护理组的婴儿中观察到渗出物(7.4%对0.3%)和恶臭(2.9%对0.7%)的可能性显著更高。
脐炎仍是一个临床问题。停止对脐带残端的杀菌护理时,必须密切关注脐炎的体征和症状。
