Other pathogens include the Streptococcus, Enterobacteriaceae, and Acinetobacter species. Patients in a NICU have a risk of Enterococcus species and group B Streptococcus as well. aeruginosa, and Klebsiella and Enterobacter species. Īrtificial airways become colonized with pathogenic bacteria soon after intubation or tracheostomy, and the major pathogens include both gram-positive and gram-negative bacteria: S. The most common organisms were Staphylococcus aureus (28.4 %), Pseudomonas aeruginosa (25.2 %), and other gram negatives (26.6%). In a large retrospective review done in the ICU settings of three hospitals, the microbiology was the same across adult and pediatric hospitals. However polymicrobial infections are increasing. Ventilator-associated pneumonia is typically bacterial and from a single organism. For convenience, the infection of an artificial airway after colonization is either diagnosed as tracheitis or ventilator-associated pneumonia. Ventilator-associated pneumonia is part of a spectrum of upper airway infection after the of an artificial airway with bacteria. Tracheitis Versus Ventilator-associated Pneumonia Infants and children are usually classified to the first category. They have classified it as three types: (1) clinically defined, (2) pneumonia with laboratory findings, and (3) pneumonia in immunocompromised patients. In 2008, the Centers for Disease Control (CDC) and National Healthcare Safety Network (NHSN) have attempted to provide reproducible criteria for the surveillance of ventilator-associated pneumonia. It is difficult to diagnose ventilator-associated pneumonia in any patient, and this holds true in young children, particularly in the neonatal ICU population. Ĭhildren with artificial airways, such as a tracheostomy tube for management of chronic respiratory failure or an endotracheal for acute airway management, are at risk for ventilator-associated pneumonia. There is limited data on infants and children with VAP, so most of the information is extrapolated from adult studies. In neonates, the rate of ventilator-associated pneumonia is inversely proportional to birth weight. Generally, the rate of pneumonia in pediatric intensive care units (PICU) is lower than in adult intensive care units (ICU). It accounts for 7% to 32% of healthcare-associated infections and 10% of all pediatric device-related infections reported to the National Healthcare Safety Network (NHSN). Ventilator-associated pneumonia (VAP) is a term used to describe pneumonia (lung infection) that develops in a patient who has been on mechanical ventilation for more than 48 hours. Ventilator-associated pneumonia is the second most common hospital-acquired infection among pediatrics and neonatal intensive care unit patients.
