Neonatal Hospital Acquired Infection
Etiology of Neonatal Hospital Acquired Infection
Interm neonates,the most frequent hospital-acquired infection is Skin infection due to Staphylococcal Infections (both methicillin-sensitive and methicillin-resistant) Although nursery personnel who areS. aureusnasal carriers are potential sources of infection, colonized neonates and mothers also may be reservoirs. The umbilical stump, nose, and groin are frequently colonized during the first few days of life. Often, infections do not manifest until the neonate is at home. 1500 g) infants, gram-positive organisms cause about 70% of infections, the majority being with coagulase-negative staphylococci. Gram-negative organisms, including Escherichia coli Infections , Infection is facilitated by the multiple invasive procedures VLBW infants undergo (eg, long-term arterial and venous catheterization, endotracheal intubation, continuous positive airway pressure, nasogastric tubes or nasojejunal feeding tubes). The longer the stay in special care nurseries and the more procedures done, the higher is the likelihood of infection.
