Insights

Preoperative oral clonidine significantly reduced postoperative nausea and vomiting (PONV) in children undergoing appendectomy. This study found fewer PONV episodes and less need for antiemetics in children who received clonidine.

Area of Science:

  • Anesthesiology
  • Pediatric Surgery
  • Pharmacology

Background:

  • Clonidine, an alpha-2 agonist, is used for sedative premedication in pediatric patients.
  • Existing literature presents conflicting data on clonidine's efficacy in preventing postoperative nausea and vomiting (PONV).

Purpose of the Study:

  • To investigate the impact of preoperative oral clonidine on the incidence of PONV in children undergoing appendectomy.

Main Methods:

  • A randomized, double-blind clinical trial involving 60 children (ages 5-12, ASA physical status I-II) scheduled for appendectomy.
  • Participants received either 4 µg/kg clonidine in apple juice or apple juice alone one hour before surgery.
  • PONV incidence and antiemetic use were monitored over 24 hours post-anesthesia.

Main Results:

  • Patient demographics were comparable between the clonidine and control groups.
  • The clonidine group experienced significantly fewer episodes of PONV compared to the control group.
  • Fewer patients in the clonidine group required rescue antiemetic medication.

Conclusions:

  • Preoperative oral administration of clonidine at 4 µg/kg effectively reduces the incidence of postoperative vomiting in pediatric appendectomy patients.
  • Clonidine demonstrates a beneficial role in managing PONV in this specific pediatric surgical population.

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: 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 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,...

Appendicitis-II: Diagnostic Studies and Management

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
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.
