The aim of this study is to compare the impact of three regimens of cord care, topical use of human milk, chlorhexidin solution and dried cord care on the cord-separation time and occurrence of bacterial colonization among neonates.
A total of 261 neonates (87 neonates in each group) will be enrolled in this randomized clinical trial. Neonates with gestational age of 42-37 weeks, which no immediate need of evaluation and treatment of the newborn, will be examined.
The infants will be randomly assigned into three groups of cord care regimens: topical application of human milk (case group), topical chlorhexidine solution (case group) and dried cord care (control group).
In group topical application of human milk, all mothers will be rubbed its own milk, and In group chlorhexidine, chlorhexidine solution 4% with a cotton swab on the abdominal skin around the base and cord stump thoroughly from three hours after birth every 12 hours to 2 days after the umbilical cord separation .In group dried cord, mother are recommended that don't used any material on cord.
In order to make sure of the presence of the microorganisms, samples of the cord stump will be collected using sterile swabs within the first three hours after birth and other visits (days 3, 7 and 2 days after umbilical cord separation)..
Researchers asked the exact date and time of the cord separation via telephone and in cases of delay in cord separation or any cord related adverse events, the newborn will be immediately visited by neonatologist.
