Anaemia may increase the risk of tissue hypoxia in preterm infants. The effect of transfusion on circulation was studied in 33 preterm infants with a mean (SD) gestational age of 29 (5) weeks (range 26-34), birth weight 1153 (390) g (range 520-1840), and postnatal age of 48 (21) days (range 19-100). Packed cell volume, blood viscosity (capillary(More)
OBJECTIVE In adults, a single dose of 250 mg of caffeine may decrease cerebral blood flow by 30%. In preterm infants, caffeine is commonly used for the treatment and prophylaxis of apnea. The purpose of this investigation was to assess effects of caffeine on circulatory parameters in preterm infants. METHODS We studied 16 preterm neonates with a mean(More)
OBJECTIVE To identify predictors of intussusception in young children. DESIGN A retrospective cross-sectional study. SETTING AND PATIENTS A consecutive sample of children younger than 5 years on whom contrast enemas were performed because of suspected intussusception seen at an urban children's hospital from 1990 to 1995. METHODS We evaluated(More)
BACKGROUND A single high loading dose of 25 mg/kg caffeine has been shown to be effective for the prevention of apnoea, but may result in considerable reductions in blood flow velocity (BFV) in cerebral and intestinal arteries. OBJECTIVE To assess the effects of two loading doses of 12.5 mg/kg caffeine given four hours apart on BFV in cerebral and(More)
Blood transfusion increases blood volume and blood viscosity of the neonate. Since both volume expansion and increase in blood viscosity may be associated with increased pulmonary artery pressure, we studied effects of transfusion (10 ml of red blood cells per kilogramme of body weight) on right ventricular output and right systolic time intervals by means(More)
