Insights

New guidelines suggest shorter preoperative fasting times for children. However, young children with severe obstructive sleep apnea (OSA) are not suitable for outpatient surgery due to increased risks.

Area of Science:

  • Anesthesiology and Perioperative Medicine
  • Pediatric Surgery
  • Sleep Medicine

Background:

  • Recent advancements in preoperative fasting guidelines for pediatric patients.
  • Increasing prevalence of pediatric obstructive sleep apnea (OSA) undergoing outpatient procedures.
  • Focus on adenotonsillectomy as a common outpatient procedure for children with OSA.

Purpose of the Study:

  • To review updated preoperative fasting guidelines for pediatric patients.
  • To analyze current research on gastric volume and fasting intervals.
  • To discuss perioperative risks and suitability of outpatient procedures for children with OSA.

Main Methods:

  • Literature review of recently published studies and guidelines.
  • Analysis of data on gastric volume, fasting intervals, and pediatric OSA.
  • Evaluation of clinical presentation, severity, and perioperative risks in pediatric OSA patients.

Main Results:

  • Widely accepted fasting guidelines: 2h for clear liquids, 4h for breast milk, 6h for formula/light meals, 8h for heavy meals.
  • Significant interpersonal variation in residual gastric volume observed.
  • Children under 3 years with OSA, or severe OSA with comorbidities, are contraindicated for ambulatory surgery.
  • Specific indications for preoperative polysomnography established.
  • Dexmedetomidine demonstrates emergence agitation reduction and opioid-sparing effects.
  • Intravenous acetaminophen and dexamethasone show efficacy as opioid-sparing analgesics and antiemetics, respectively, without increased bleeding risk.
  • Surgical techniques can influence postoperative pain.

Conclusions:

  • Liberalized preoperative intake is recommended, with updated fasting times.
  • Careful patient selection is crucial; certain pediatric OSA patients are unsuitable for outpatient surgery.
  • Pharmacological interventions like dexmedetomidine, IV acetaminophen, and dexamethasone can optimize perioperative care.
  • Surgical approach impacts postoperative pain management.

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption01:23

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...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
Parenteral Anesthetics: Overview01:24

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.
Pharmacokinetics in Pediatric Patients: Drug Metabolism01:24

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
