Insights

Hypoglycemia poses a risk to newborns needing resuscitation. Epinephrine administration during resuscitation impacted blood glucose levels differently in premature versus term infants, with premature infants showing higher hypoglycemia risk.

Area of Science:

  • Neonatalogy
  • Perinatal Medicine
  • Pediatric Endocrinology

Background:

  • Hypoglycemia is a critical risk factor for perinatal brain injury.
  • Infants requiring resuscitation after hypoxic-ischemic (HI) insult are particularly vulnerable.
  • Blood glucose (BG) management is crucial in stressed newborns.

Purpose of the Study:

  • To investigate blood glucose (BG) levels in physiologically stressed infants.
  • To compare BG levels with and without epinephrine (Epi) administration during resuscitation.
  • To analyze BG trends in the first 24 hours after birth.

Main Methods:

  • Retrospective chart review of infants with heart rate <100/min at 1 minute requiring positive pressure ventilation (PPV).
  • Infants categorized into PPV-only group or epinephrine (Epi) group for persistent bradycardia.
  • Serial BG measurements and glucose infusion rate (GIR) at 24 hours were analyzed.

Main Results:

  • Epinephrine group infants had lower cord pH and higher base deficit.
  • Premature infants (≤32 weeks) in the Epi group showed significantly lower BG over time.
  • Near-term and term infants in the Epi group had higher BG compared to the PPV group.
  • Hypoglycemia was more prevalent in premature infants despite higher GIR.

Conclusions:

  • Premature infants (≤32 weeks) are at higher risk for hypoglycemia during physiological stress.
  • Epinephrine administration during resuscitation has differential effects on blood glucose in premature vs. term infants.
  • Close blood glucose monitoring is essential in all infants undergoing resuscitation, especially premature infants.

Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Glucose Homeostasis: Regulation of Blood Glucose01:02

Glucose Homeostasis: Regulation of Blood Glucose

Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Glucose Transporters01:27

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Metabolic States of the Body: The Postabsorptive State01:18

Metabolic States of the Body: The Postabsorptive State

The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

Hormones Regulating Blood Glucose01:16

Hormones Regulating Blood Glucose

Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...
