Summary

This study tests different doses of alfentanil (a painkiller) combined with propofol (a sleep medicine) to find the best amount for placing a laryngeal mask airway in children aged 7 to 12. The goal is to make the procedure smoother and safer. Forty children having day surgery will take part, and the dose will be adjusted based on how well each child responds.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
alfentanil and propofol
What this could lead to
If successful, this could help anesthesiologists use the safest, most effective doses of these drugs for children, reducing complications during surgery.
What could go wrong
This is a small, early-phase study with only 40 children, so results may not apply to all kids or settings. The drugs can cause side effects like breathing problems or low blood pressure.
