Insights

Sublingual dexmedetomidine offers superior preoperative sedation in children compared to midazolam, ensuring smoother anesthesia induction and recovery, particularly for preschoolers. This study highlights its effectiveness in pediatric surgical settings.

Area of Science:

  • Pediatric Anesthesiology
  • Pharmacology
  • Surgical Premedication

Background:

  • Premedication reduces preoperative anxiety and aids anesthesia induction in children.
  • Midazolam, a common pediatric premedicant, has drawbacks like postoperative behavioral changes.
  • Dexmedetomidine, a selective alpha-2 adrenergic agonist, offers sedation mimicking natural sleep and aids recovery.

Purpose of the Study:

  • To compare the effectiveness of sublingual dexmedetomidine versus sublingual midazolam as a premedicant in pediatric patients.
  • To evaluate sedation levels, induction behavior, mask acceptance, and wake-up behavior.

Main Methods:

  • Prospective, randomized, double-blind study of 100 children (1-12 years, ASA I/II).
  • Group I received sublingual midazolam (0.25 mg/kg); Group II received sublingual dexmedetomidine (1.5 µg/kg).
  • Assessed sedation, induction behavior, mask acceptance, and wake-up behavior using standardized scores.

Main Results:

  • Dexmedetomidine group showed significantly lower sedation scores at parental separation (3.5 vs. 6, P<0.001).
  • Preschoolers exhibited better mask acceptance and wake-up behavior with dexmedetomidine (scores of 1 vs. 2, P<0.001).
  • Behavior at induction was comparable; scores were similar in school-aged children.

Conclusions:

  • Sublingual dexmedetomidine is more effective for preoperative sedation than sublingual midazolam in children.
  • Dexmedetomidine facilitates smoother anesthesia induction and awakening, especially in preschool-aged children.
  • Offers a potentially improved alternative to midazolam for pediatric surgical premedication.

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.
Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Sedatives and Hypnotics: Overview01:23

Sedatives and Hypnotics: Overview

Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve 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...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
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...
