Insights

Dolasetron effectively prevents postoperative vomiting (POV) in children undergoing strabismus surgery. Both weight-based and fixed doses significantly reduced emesis compared to placebo.

Area of Science:

  • Pediatric Anesthesiology
  • Pharmacology
  • Surgical Outcomes

Background:

  • Postoperative vomiting (POV) is a common complication in pediatric strabismus surgery.
  • Effective antiemetic strategies are crucial for patient recovery and reducing healthcare costs.

Purpose of the Study:

  • To evaluate the efficacy and safety of dolasetron in preventing POV in children.
  • To compare two dolasetron dosing regimens (0.35 mg/kg vs. 12.5 mg fixed dose) against a placebo.

Main Methods:

  • A double-blind, randomized study involving 118 children (2-12 years) undergoing strabismus surgery.
  • Patients received either dolasetron (weight-based or fixed dose) or placebo 15 minutes before surgery end.
  • Outcomes included acute complete response (ACR), time to awakening, and PACU length of stay.

Main Results:

  • Acute complete response (no emesis or rescue medication within 24 hours) was achieved in 62% (weight dose) and 64% (fixed dose) of patients.
  • This is significantly higher than the 33% observed in the placebo group (P < 0.05).
  • No statistical difference in efficacy was noted between the two dolasetron doses.

Conclusions:

  • Both weight-based (0.35 mg/kg) and fixed (12.5 mg) doses of dolasetron are effective in reducing the incidence of postoperative vomiting.
  • Dolasetron represents a safe and effective option for preventing emesis in pediatric patients undergoing strabismus surgery.

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists

Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates these...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

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...
