A scoring system was developed to objectively evaluate the condition of transported preterm infants. The "transport score" used five variables: blood glucose, blood pressure, pH, pO2, and temperature. Each variable was scored 0, 1, or 2, with a total achievable score from 0 to 10. Twenty-one matched pairs of infants included one infant who lived and one who(More)
Although nucleated red blood cells (nRBCs) are rarely found circulating in older children, they are commonly seen in the blood of newborns. They are primarily produced in the fetal bone marrow in response to erythropoietin and are stored in the marrow as precursors to reticulocytes and mature erythrocytes. Many acute and chronic stimuli cause increases in(More)
Central and peripheral intravascular catheters serve many important functions for sick neonates; however, the use of these catheters also carries significant risk of permanent disability or even death. This article examines the risks of catheter-related thromboembolic events, vasospasm, and infection. The article also looks at risks that are specific to(More)
The radioactive microsphere technique was used in 13 newborn dogs to determine the effect of a metabolic (lactic)acidosis upon cardiac output (CO), cerebral blood flow (CBF), and autoregulation of cerebral blood flow. The animals were mechanically ventilated with supplemental oxygen to ensure normocarbia and hyperoxia throughout the experiments. Baseline(More)
Ten percent of all newborns require resuscitation at birth. The Neonatal Resuscitation Program establishes the authoritative technique of newborn resuscitation. Errors continue to occur that are related to the use of unskilled resuscitators; intubation; inadequate suctioning of meconium; and the postresuscitation problems of hypoglycemia, hypocarbia, and(More)
Reports of isolated cases of necrotizing enterocolitis following administration of mydriatric medication and ophthalmologic examination prompted a comparison of the incidence of feeding difficulties 24 hours before and 24 hours after the ophthalmologic examination of 50 newborns. All infants had received cyclopentolate hydrochloride and phenylephrine(More)
