Pressure ulcer (PU) is a localized trauma to the skin and or tissue beneath which lies in bony prominence due to pressure or pressure that combines with sharp surface. Several studies have found that PU is also a common problem in pediatrics population. Infection at the site of a PU is the most common complication, in which the PU may host a resistant microorganism and may turn into a local infection that is a source of bacteremia in hospital patients. Cross-sectional studies in 18 PU pediatric patients are measured to determine the bacterial pattern. This study found that the most common microbial pattern in pressure ulcers pediatric patients is Acinetobacter baumannii (22.2%).
