Successful and Rapid Reduction in Neurosedative and Analgesic Medications in Complex Infants with Severe Bronchopulmonary Dysplasia After Tracheostomy Placement: Experience with 24-hour Propofol Infusions.

Infants with severe bronchopulmonary dysplasia may require high doses of neurosedative medications to ensure pain control and stability following tracheostomy placement. Subsequent weaning of these medications safely and rapidly is a challenge. We describe a 24-hour propofol infusion to reduce neurosedative medications in 3 high-risk infants following tracheostomy placement.

Coordinated changes in hepatic amino acid metabolism and endocrine signals support hepatic glucose production during fetal hypoglycemia.

Reduced fetal glucose supply, induced experimentally or as a result of placental insufficiency, produces an early activation of fetal glucose production. The mechanisms and substrates used to fuel this increased glucose production rate remain unknown. We hypothesized that in response to hypoglycemia, induced experimentally with maternal insulin infusion, the fetal liver would increase uptake of lactate and amino acids (AA), which would combine with hormonal signals to support hepatic glucose production.
