Effect of Remifentanil on Postoperative Vomiting After Strabismus Surgery in Preschool Children: A Prospective...

Area of Science:

• Anesthesiology
• Pediatric Surgery
• Pharmacology

Background:

• Postoperative vomiting is a common concern following strabismus surgery.
• Opioid use is a known risk factor for postoperative vomiting.
• The study aimed to investigate remifentanil's role in this complication.

Purpose of the Study:

• To evaluate the dose-dependent effect of remifentanil on the incidence of postoperative vomiting in pediatric patients undergoing strabismus surgery.
• To compare the incidence of postoperative vomiting between high-dose, low-dose, and no remifentanil groups.

Main Methods:

• Sixty pediatric patients were randomized into three groups: high-dose remifentanil, low-dose remifentanil, and control.
• Remifentanil was administered intravenously as a bolus and continuous infusion during surgery.
• Postoperative pain was managed with fentanyl in all groups.

Main Results:

• No significant difference in the incidence of postoperative vomiting within 24 hours was observed between the three groups.
• Emergence agitation and postoperative pain levels were also similar across all groups.
• Intraoperative remifentanil administration did not correlate with reduced or increased vomiting.

Conclusions:

• Intraoperative remifentanil does not appear to have a dose-dependent effect on postoperative vomiting in pediatric strabismus surgery.
• Further research may be needed to explore alternative antiemetic strategies.
• Current findings suggest remifentanil's dose does not influence this specific postoperative outcome.
