Insights

Infants undergoing anesthesia are at risk for hyperketonemia. Older infants and afternoon surgeries increase this risk, even with glucose administration. Careful patient selection and timing are key for preventing high ketone levels.

Area of Science:

  • Pediatric Anesthesiology
  • Metabolic Disorders
  • Infant Health

Background:

  • Hyperketonemia in infants can result from lipid catabolism during anesthesia.
  • Glucose administration is used to prevent hyperketonemia, but risk factors require further investigation.

Purpose of the Study:

  • To identify risk factors for hyperketonemia in infants receiving glucose during general anesthesia.
  • Investigate the impact of patient age, anesthesia start time, and preoperative fluid intake.

Main Methods:

  • 147 healthy infants (2-24 months) were studied, divided into cleft lip and cleft palate groups.
  • Preoperative fluid intake and intraoperative glucose infusion (195 mg/kg/hour) were standardized.
  • Blood ketone bodies (β-hydroxybutyrate) and glucose levels were measured at anesthesia induction and 2 hours post-induction.

Main Results:

  • Abnormally high ketone body concentrations (≥ 1.0 mmol/L) were found in 34 infants.
  • Age (P = .001), specifically the cleft palate group (P < .001), and afternoon anesthesia start times (P = .003) were significantly associated with hyperketonemia.
  • No significant difference in preoperative liquid intake was observed between groups.

Conclusions:

  • Age group (cleft palate) and afternoon anesthesia start times are significant risk factors for hyperketonemia in infants.
  • These findings aid in optimizing anesthetic management to prevent hyperketonemia in pediatric patients.

Parenteral Anesthetics: Overview

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

General Anesthesia: Overview

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...
Inhalational Anesthetics: Overview01:20

Inhalational Anesthetics: Overview

Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
