Cards Term when is perinatal period? Definition 28 completed weeks of pregers to the 7th completed day after birth Term what are categories of perinatal death? Definition Consequence of pre-term birth; Disorders of utero-placental circulation; Infection; Developmental anomalies; Specific disorders; Unexplained Term why are premmies ill? Definition organs are immature, and therefore unable to adapt readily to extrauterine life. Although most preterm neonates have a low birth weight, not all lowbirth weight infants are preterm. Term why else can low birth weight occur? Definition failure of the fetus to grow appropriately during gestion (fetal growth restriction)--so low birthweight babies can be born to term!! Term what ar causes for intrauterine growth retardation? Definition Chromosomal disorders and developmental anomalies Fetal infections Disorders of utero-placental circulation Maternal malnutrition and diseases Drugs Term what are the complications of prematurity? Definition 1. Respiratory Distress Syndrome 2. Intraventricular Hemorrhage 3. Necrotizing Enterocolitis Term what is the acute phase of respiratory distress syndrome? Definition haline membrane disease Term what is the chronic phase? Definition bronchopulmonary dysplasia Term hyaline membrane disease Definition Difficult breathing within 30’ after birth Clinical course depends on degree of prematurity and therapy employed Hypoxemia, hypercarbia and metabolic acidosis Chracteristic chest x-ray (ground glass picture) intesne vascular congestion, necrosis of epithelial lining of distal airways, alternating atelectasis (collapse of previously inflated lung) and dialated respiratory brochioles lined by pink hyaline membranes Term hyaline membrane disease path? Definition Epithelial necrosis; Pulmonary congestion and edema; Alternating atelectasis and dilated ;respiratory bronchioles; Hyaline membranes Term bronchopulmonary dysplasia Definition abnormal growth of the lung. Persistence of respiratory distress for up to 3 to 6 months or more Abnormal lung growth that follows acute lung injury. Term bronchopulmonary dysplasia pathology? Definition Alternating areas of overinflation and collapse Interstitial fibrosis Epithelial regeneration with squamous metaplasia in conducting airways Abnormal vascular and alveolar development (“new” BPD) Term intraventricular hemorrhage Definition Subependymal germinal matrix vasculature Pressure/flow changes and hypoxia Term necrotizing enterocolitis Definition Coagulation necrosis and inflammation; Terminal ileum, cecum and ascending colon; Preterm neonates Term complications of necrotizing enterocolitis? Definition Early: Perforation Peritonitis Sepsis and shock Late: Strictures Short bowel syndrome Malabsortion
