The umbilical cord of the newborn did not fall off with a slight bleeding may be physiological factors, such as diaper abrasions caused by the replacement of diapers can be relieved; may also be umbilical cord inflammation, neonatal hemorrhagic disease and coagulation abnormalities and other pathological factors lead to, should be timely consultation and treatment of the primary pathology, the symptoms will be relieved. 1. Physiological factors: wearing diapers too tight or diapers are too rough resulting in local abrasions, this situation can be replaced with larger or soft texture diapers, and at the same time through the local disinfection, to strengthen the protection of the navel, the symptoms will soon be relieved. 2. Pathological factors: (1) Umbilical inflammation: Umbilical inflammation often occurs in the 6~8 days after the birth of the newborn, at this time the umbilical cord has not yet fallen off, the umbilical cord nest has a small amount of blood, accompanied by the umbilical chakra red and swollen, this situation needs to do the umbilical cord care, you can use 75% of disinfectant alcohol at the root of the umbilical cord to disinfect the root of the umbilicus, care for 2~3 times a day until the bleeding is reduced. (2) Neonatal hemorrhagic syndrome: also known as neonatal vitamin K deficiency hemorrhagic syndrome, this case is often bleeding for a long time, under the guidance of the doctor should be given to newborns applying vitamin K, which can play a role in stopping bleeding. (3) Abnormal coagulation function: abnormal coagulation function in the early neonatal period will lead to the phenomenon of umbilical cord bleeding that is not easy to stop, and should consult a doctor in time to check the specific causes, and in serious cases, it is necessary to supplement coagulation factors, so that the plasma concentration of coagulation factors reaches the level of coagulation, thus reducing the bleeding situation. In the clinical situation, if the umbilical cord of a newborn baby is not detached and there is slight bleeding, if physiological factors are ruled out and not relieved, it is necessary to consult a doctor in time to find out the cause and treat the cause of the bleeding.
