Study Notes

Neonatal Glycemic Control and Parenteral Nutrition

Neonates receiving parenteral nutrition (PN) are at a higher risk of hyper- and hypoglycemia, leading to negative outcomes.
Untreated hyper- or hypoglycemia can result in neurodevelopmental impairment, dehydration, and electrolyte imbalance, and increased morbidity and mortality in premature infants.

A.S.P.E.N. Clinical Guidelines

The American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) aims to improve patient care by advancing the science and practice of clinical nutrition and metabolism.
A.S.P.E.N. has been publishing Clinical Guidelines since 1986 and evaluates when individual guidelines should be updated.

Determining Blood Glucose Concentration in Neonates

Blood glucose concentration in neonates should be determined using laboratory serum glucose or glucose electrode measurements, rather than point of care reagent test strips.
Point of care reagent test strips may be susceptible to errors due to contamination with alcohol, elevated hematocrit, and a 15% lower glucose concentration compared to laboratory plasma glucose values.

Blood Glucose Concentration and Clinical Complications in Neonates

Moderate and severe hyperglycemia in premature very low birth weight (VLBW) infants are associated with increased mortality rates.
Mortality rates for different levels of blood glucose are as follows: normoglycemia (13.4%), moderate hyperglycemia (7.2%), and severe hyperglycemia (22.2%).
Maximum serum glucose levels are positively correlated with the duration of parenteral nutrition, the number of days on the ventilator, and the length of stay in the hospital.
Keeping the serum glucose concentration < 150 mg/dL is recommended to reduce clinical complications.

Hyperglycemia and Neonatal Outcomes

Hyperglycemia is associated with increased risk of retinopathy of prematurity (ROP), intraventricular haemorrhage (IVH), and mortality in extremely low birth weight (ELBW) infants.
Hyperglycemia is a strong indicator of early death or IVH in ELBW infants, with a sensitivity of 91% and specificity of 25%.
Mild to moderate hyperglycemia is not significantly linked to death or infection, after adjusting for age.
Stress is linked to higher mortality rates and IVH, although it is not significantly associated with hyperglycemia.
