Summary

Dexamethasone significantly reduced vomiting in children after tonsillectomy. This steroid effectively prevented both in-hospital and post-discharge emesis, improving patient recovery.

Area of Science:

  • Pediatric Anesthesiology
  • Pharmacology
  • Surgical Outcomes

Background:

  • Post-tonsillectomy nausea and vomiting (PONV) are common in children.
  • Effective antiemetic strategies are crucial for pediatric ambulatory surgery.
  • Dexamethasone is a potential agent for managing PONV.

Purpose of the Study:

  • To evaluate the efficacy of dexamethasone in preventing vomiting after elective tonsillectomy in children.
  • To assess the impact of dexamethasone on in-hospital and post-discharge vomiting.
  • To determine the effect of vomiting episodes on hospital discharge time.

Main Methods:

  • A randomized, double-blind, placebo-controlled trial involving 133 children aged 2-12 years undergoing tonsillectomy.
  • Participants received either intravenous dexamethasone (150 mcg/kg, max 8 mg) or placebo before surgery.

  • Standardized anesthesia, intraoperative codeine, fluid management, and discharge criteria were applied.

    • Main Results:

    • Dexamethasone reduced the overall incidence of vomiting from 72% in the placebo group to 40% (P < 0.001).
    • Prophylactic dexamethasone decreased both in-hospital and post-discharge vomiting episodes.
    • Each in-hospital vomiting episode prolonged discharge by an average of 13 minutes (P < 0.001).

    Conclusions:

    • Dexamethasone is highly effective in reducing vomiting after elective tonsillectomy in healthy children.
    • Prophylactic dexamethasone administration improves recovery and shortens discharge time in pediatric ambulatory tonsillectomy.
    • This finding supports the use of dexamethasone as an antiemetic in pediatric tonsillectomy settings.
