Insights

Early oral fluid intake in the postanesthesia care unit (PACU) reduces vomiting in pediatric patients after surgery. This practice does not increase nausea, promoting faster recovery.

Area of Science:

  • Anesthesiology
  • Pediatric Surgery
  • Evidence-Based Medicine

Background:

  • Postoperative nausea and vomiting (PONV) are common complications in pediatric patients following general anesthesia.
  • Current practices for oral intake in the postanesthesia care unit (PACU) vary, impacting patient recovery.
  • Optimizing early recovery protocols is crucial for pediatric surgical patients.

Purpose of the Study:

  • To systematically review and meta-analyze the impact of early versus delayed oral fluid intake on nausea and vomiting in pediatric patients in the PACU.
  • To assess the safety and efficacy of early oral refeeding post-anesthesia in children.

Main Methods:

  • Systematic review and meta-analysis of randomized controlled trials (RCTs) conducted up to July 2023.
  • Searched multiple electronic databases (PubMed, CINAHL, Embase, Cochrane CENTRAL, etc.).
  • Assessed risk of bias using the Risk of Bias 2 tool and certainty of evidence with GRADE.

Main Results:

  • Meta-analysis of 6 RCTs (2,723 patients) showed early oral intake significantly decreased vomiting incidence by 36% (RR=0.64, 95% CI: 0.42-0.97) with moderate certainty.
  • Meta-analysis of 3 RCTs (2,185 participants) indicated early oral intake did not increase nausea (95% CI: -0.76-0.07) with low certainty.
  • Evidence suggests early oral fluid intake is associated with reduced vomiting and no increased nausea.

Conclusions:

  • Early oral fluid intake in the PACU is effective in reducing postoperative vomiting in pediatric patients.
  • This intervention does not appear to increase the incidence of postoperative nausea.
  • Healthcare providers should consider implementing early oral fluid intake to enhance recovery in pediatric surgical patients.

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 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: 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,...

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...

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.

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
