Insights

Prophylactic strategies for pediatric postoperative nausea and vomiting (PONV) primarily focus on pharmacologic interventions. More research is needed on nonpharmacologic and mixed approaches for pediatric PONV prevention.

Area of Science:

  • Anesthesiology
  • Pediatric Surgery
  • Evidence-Based Medicine

Background:

  • Postoperative nausea and vomiting (PONV) is a frequent complication in pediatric patients under general anesthesia.
  • Effective prophylactic interventions are crucial for patient well-being and optimizing perioperative care.

Purpose of the Study:

  • To systematically review the evidence on prophylactic strategies for pediatric PONV.
  • To assess both pharmacologic and nonpharmacologic interventions targeting pediatric PONV.

Main Methods:

  • Comprehensive literature search across multiple databases (MEDLINE, Embase, Cochrane, etc.) up to September 2022.
  • Included 188 clinical trials investigating various PONV prophylaxis methods.
  • Identified common surgical contexts (strabismus, tonsillectomy) and assessment tools (clinical judgment).

Main Results:

  • The vast majority of trials (83%) focused on pharmacologic interventions for pediatric PONV.
  • Nonpharmacologic and mixed interventions were investigated in a smaller proportion of studies (13% and 3%, respectively).
  • Clinical judgment was the predominant method for assessing PONV in the reviewed trials.

Conclusions:

  • Current research on pediatric PONV prophylaxis is heavily weighted towards pharmacologic agents.
  • There is a significant gap in research regarding nonpharmacologic and combined prophylactic strategies.
  • Standardized assessment tools (e.g., Baxter Animated Retching Faces Scale) and concurrent evaluation of pain/adverse effects are recommended for future research.

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...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

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: Dopamine Receptor Antagonists01:29

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...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

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.

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...
