OBJECTIVE The obstetric and neonatal exploratory focus group of the Vermont Oxford Network Neonatal Intensive Care Quality Improvement Collaborative 2002 set out to improve collaboration, communication, and coordination between maternal and neonatal caregivers in 3 areas: the pregnancy at 22 to 26 weeks, measurement of maternal outcomes that are linked with(More)
The effect of progressive increases in ventilator rate on delivered tidal and minute volumes, and the effect of changing peak inspiratory pressure (Pmax), positive end-expiratory pressure (PEEP), and inspiration to expiration (I:E) ratio at different ventilator rates were examined. Five different continuous-flow, time-cycled, pressure-preset infant(More)
OBJECTIVES The objective of this study was to determine the attitudes of a variety of health care providers toward the recommendations that should be made to parents regarding the resuscitation of infants who are born at the margins of viability. METHODS A written questionnaire was distributed to the medical and nursing staff at 4 tertiary perinatal(More)
A study of 534 febrile infants ages 4 to 8 weeks evaluated for sepsis assessed the efficacy of the Milwaukee Protocol (MP) for selecting patients at low risk for serious bacterial infection (SBI) who might benefit from outpatient management. Two groups were compared: 1) Infants with uncompromised presentation (UP) who met all MP criteria received(More)
Mass spectra were recorded using direct inlet and electron impact ionization from two synthetic peptides, N-acetyl-aspartyl-4-aminobutyric acid and gamma-glutamyl-taurine and a natural peptide, N-acetyl-aspartyl-glycyl-alanyl-aspartyl-serine, isolated from calf brain synaptosomes. The peptides were studied either underivatized or first acetylated with(More)
BACKGROUND Although reports of reduced nosocomial infections (NI) in very low birth weight infants have been published, the durability of these gains and changes in secondary outcomes, and clinical practices have less often been published. METHODS This was a retrospective, observational study of NI reduction in very low birth weight infants at two(More)
We describe the development of a database of quality indicators and outcomes for perinatal care as part of a multi-institutional collaborative quality improvement project, Neonatal Intensive Care Quality 2002. Important principles of developing such a database are also discussed including eligibility criteria that identify high-risk patients without(More)
Effects of high frequency ventilation (HFV), such as apnea, are mediated by the autonomic nervous'system. To further define these effects, we studied an important autonomic reflex, the baroreflex, during HFV and conventional ventilation (CV) of 5 young adult male rabbits anesthetized with chloralose and paralyzed with metocurine. To keep FRC constant during(More)
We studied 6 chronically instrumented newborn lambs during normoxia (N) and hypoxia (H) on alternating days during infusion of isoproteronol (I) from .062 to 2.5 mcg/kg/min while measuring PAP, LAP, SAP, pulmonary flow (QP) heart rate (HR) and blood gases. Pulmonary (PVR) and systemic vascular resistance (SVR) and PVR/SVR were calculated. Infusion during N(More)
Neonatal cerebral infarction (CI) is usually associated with risk factors such as birth trauma, asphyxia or coagulopathy, but there are reports of “idiopathic” infarctions without apparent risk factors. We have seen 2 cases of left middle cerebral artery (MCA) infarction presenting with seizures by one day of age in infants with “moderate” risk factors(More)
