Brain-Wave-Guided anesthesia may cut opioid use in Kids' surgery
NCT ID NCT07714785
First seen Jul 20, 2026 · Last updated Sep 09, 2026 · Updated 5 times
Summary
This trial investigates whether using EEG brain-wave monitoring to adjust sevoflurane anesthesia can reduce opioid use and improve recovery in children aged 2-8 years undergoing tonsillectomy. Half of the children receive standard anesthesia, while the other half have their anesthesia dose fine-tuned to maintain a specific brain-wave pattern. The study measures opioid consumption, emergence delirium, and postoperative pain.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- EEG-guided sevoflurane titration (procedure)
- What this could lead to
- If successful, this approach could reduce opioid use and improve recovery quality in children after surgery.
- What could go wrong
- This is a small, early-stage trial with only 50 children, so results may not apply broadly. The EEG-guided method may not significantly reduce opioid consumption or improve outcomes.
