Anesthesia and Analgesia
|August 9, 2011
Summary
Dexmedetomidine is an effective pediatric sedative with minimal respiratory effects but can cause cardiovascular changes like bradycardia and hypertension. Careful monitoring is essential for safe use in children.
Area of Science:
- Anesthesiology
- Pediatric Pharmacology
Background:
- Dexmedetomidine is increasingly used in pediatric anesthesia.
- Over 200 studies exist on its use in infants and children.
Purpose of the Study:
- To review the English literature on dexmedetomidine in pediatric patients.
- To summarize current knowledge for practicing anesthesiologists.
Main Methods:
- Literature review of English-language studies and reports.
- Synthesis of existing data on dexmedetomidine's effects in children.
Main Results:
- Dexmedetomidine provides effective sedation with minimal respiratory depression and maintains airway patency.
- Cardiovascular effects include bradycardia, hypotension, and hypertension, varying with age and dose.
- Hypertension is more common in infants with higher doses.
- Recovery may be prolonged due to its 2-hour elimination half-life.
- It offers analgesia, reduces shivering, and decreases postoperative agitation.
Conclusions:
- Dexmedetomidine is safe and effective in children when used with appropriate monitoring.
- Management of cardiovascular side effects is crucial for safe pediatric use.

01:19Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...

01:24Parenteral 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.
01:29Drug 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...
01:26Pharmacokinetics 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...
01:23Pharmacokinetics 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...
01:20Inhalational 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...
