Neonatal sepsis specifically refers to the presence in a newborn baby of a bacterial blood stream infection (BSI) (such as meningitis, pneumonia, pyelonephritis, or gastroenteritis) in the setting of fever. Older textbooks may refer to neonatal sepsis as "sepsis neonatorum". Criteria with regards to hemodynamic compromise or respiratory failure are not useful clinically because these symptoms often do not arise in neonates until death is imminent and unpreventable. Neonatal sepsis is divided into two categories: early-onset sepsis (EOS) and late-onset sepsis (LOS). EOS refers to sepsis presenting in the first 7 days of life (although some refer to EOS as within the first 72 hours of life), with LOS referring to presentation of sepsis after 7 days (or 72 hours, depending on the system used). neonatal sepsis is the single most important cause of neonatal death in hospital as well as community in developing country. It is difficult to clinically exclude sepsis in newborns less than 90 days old that have fever (defined as a temperature > 38°C (100.4°F). Except in the case of obvious acute viral bronchiolitis, the current practice in newborns less than 30 days old is to perform a complete workup including complete blood count with differential, blood culture, urinalysis, urine culture, and cerebrospinal fluid (CSF) studies and CSF culture, admit the newborn to the hospital, and treat empirically for serious bacterial infection for at least 48 hours until cultures are demonstrated to show no growth. Attempts have been made to see whether it is possible to risk stratify newborns in order to decide if a newborn can be safely monitored at home without treatment despite having a fever. One such attempt is the Rochester criteria. ==Signs and symptoms== The signs of sepsis are non-specific and include:〔(【引用サイトリンク】title=Updating PubMed Health )〕 *Body temperature changes * Breathing problems *Diarrhea *Low blood sugar *Reduced movements *Reduced sucking *Seizures *Bradycardia *Swollen belly area *Vomiting *Yellow skin and whites of the eyes (jaundice) A heart rate above 160 can also be an indicator of sepsis, this tachycardia can present up to 24 hours before the onset of other signs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「neonatal sepsis」の詳細全文を読む スポンサード リンク
