Insights

Hyperglycemia is common in pediatric intensive care units (PICUs), affecting 89% of ventilated children and increasing the risk of organ failure and death. However, early hyperglycemia does not predict later organ dysfunction, and insulin use is rare.

Area of Science:

  • Pediatric Critical Care Medicine
  • Endocrinology
  • Clinical Research

Background:

  • Hyperglycemia is a frequent complication in critically ill children.
  • Understanding its prevalence and impact in pediatric intensive care units (PICUs) is crucial for patient outcomes.

Purpose of the Study:

  • To determine the prevalence of hyperglycemia in ventilated children.
  • To assess the association between hyperglycemia and organ failure.
  • To document glycemic control practices in Australasian PICUs.

Main Methods:

  • Prospective inception cohort study conducted in nine specialist PICUs across Australia and New Zealand.
  • Included 409 children ventilated for over 12 hours, excluding specific conditions.
  • Collected blood glucose measurements, clinical data for PELOD scores, and insulin use for up to 14 days.

Main Results:

  • 89% of patients experienced peak blood glucose levels > 6.1 mmol/L, with hyperglycemia identified in 13% of subjects.
  • Hyperglycemia was independently associated with a higher Paediatric Logistic Organ Dysfunction (PELOD) score (≥10) and increased mortality.
  • Early hyperglycemia (first 48 hours) showed associations with outcomes but not with later or worsening organ failure.

Conclusions:

  • Hyperglycemia is prevalent, occurs early, and is linked to organ failure and death in PICU patients.
  • Early hyperglycemia is not predictive of subsequent or escalating organ dysfunction.
  • Insulin therapy is infrequently utilized in Australasian PICUs.

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...
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...
Hyperglycemia01:29

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
Complications of Diabetes Mellitus01:22

Complications of Diabetes Mellitus

Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...
Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are co-secreted in...

Diabetic Ketoacidosis ll: Pathophysiology

Diabetic ketoacidosis (DKA) is a metabolic emergency characterized by hyperglycemia, ketonemia, and metabolic acidosis. It results from severe insulin deficiency and an excess of counterregulatory hormones, leading to uncontrolled lipolysis, ketogenesis, and widespread electrolyte and fluid disturbances.Pathophysiology The central event in DKA is a profound loss of insulin action. Without insulin, glucose uptake in insulin-dependent tissues is impaired, while hepatic glucose production...
