    Insights

    Gastric aspiration after tonsillectomy does not reduce vomiting in children. This study found no significant difference in vomiting incidence, episodes, or anti-emetic needs between groups receiving or not receiving gastric aspiration.

    Area of Science:

    • Otolaryngology
    • Pediatric Surgery
    • Anesthesiology

    Background:

    • Postoperative nausea and vomiting (PONV) are common after tonsillectomy, affecting one-third of patients.
    • Effective interventions to reduce PONV in pediatric tonsillectomy patients are crucial.

    Purpose of the Study:

    • To evaluate the efficacy of gastric decompression via gastric aspiration in minimizing post-tonsillectomy vomiting.
    • To assess its impact on associated complications in pediatric patients.

    Main Methods:

    • A randomized controlled trial was conducted with 54 pediatric patients undergoing tonsillectomy.
    • Patients were divided into two groups: one receiving gastric aspiration with an oro-gastric tube under general anesthesia, and a control group without aspiration.
    • Data collected included vomiting incidence, number of episodes, and need for rescue anti-emetics.

    Main Results:

    • No statistically significant differences were observed between the gastric aspiration group and the control group.
    • Vomiting incidence (33% vs. 41%, p=0.389), mean episodes of vomiting (0.71 vs. 0.88, p=0.555), and the need for rescue anti-emetics (11% vs. 15%, p=0.500) were comparable.
    • These findings indicate gastric aspiration did not significantly reduce PONV.

    Conclusions:

    • Gastric aspiration performed during tonsillectomy does not effectively reduce the incidence or severity of post-tonsillectomy vomiting in children.
    • The routine use of gastric aspiration for preventing PONV in this pediatric population is not supported by this study's findings.

    Chronic Pharyngitis

    Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
    Etiology
    It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
    Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

    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,...
