Bloody stool is a main focus in non-neonatal intensive care unit ward, and it is one of the risk factors in neonates with subsequent necrotizing enterocolitis(NEC) and usually lead to longed duration of hospitalization. NEC is one of the most serious disease in the newborn infants, and two and more grades of NEC might lead to surgery, even death. But, it is difficult to predict when the bloody stool comes and develop to two and more grades of NEC.
NEC is characterized by vomit, abdominal distention, hypoactive bowel sounds and bloody stools, even shock, disseminated intravascular coagulation(DIC) and sepsis. X-ray is shown Intestinal wall gas and/or portal vein pneumatosis and pneumoperitoneum. Bloody stool in newborn infant is a urgent condition, and neonatologist usually need to predict whether or not two and more grades of NEC it is. Here, the investigators will develop a score system in one retrospective cohort to predict bloody stool, and the score system is validated in another prospective cohort.
