Umbilicusinfektionen

Umbilicusinfektionen, also known as umbilical infections, are bacterial infections of the umbilical stump in newborns. This condition is relatively common and can range from mild inflammation to more serious systemic infections. The umbilical stump is the remnant of the umbilical cord after birth and typically dries up and falls off within one to three weeks. During this period, it is susceptible to bacterial colonization and subsequent infection, especially if proper hygiene is not maintained.

Risk factors for developing an umbilical infection include premature birth, low birth weight, prolonged rupture of membranes, and inadequate cord care. The most common causative agent is Staphylococcus aureus, followed by Streptococcus species and Gram-negative bacteria like Escherichia coli. Symptoms can include redness, swelling, and tenderness around the umbilical stump. A foul-smelling discharge, often purulent, may also be present. In more severe cases, signs of systemic infection such as fever, lethargy, poor feeding, and jaundice can occur.

Diagnosis is typically made based on the clinical presentation. If a systemic infection is suspected, blood cultures and other laboratory tests may be performed. Treatment depends on the severity of the infection. For localized infections, topical antibiotics may be sufficient. More severe infections often require systemic antibiotic therapy. In rare cases, surgical intervention might be necessary. Prevention is key and involves maintaining good hygiene, keeping the umbilical stump clean and dry, and avoiding tight dressings. Healthcare providers educate parents on proper cord care to minimize the risk of infection.
