Can a pulse oximeter detect pain relief in kids under anesthesia?
NCT ID NCT07703384
First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time
Summary
This study looks at two non-invasive monitors—the perfusion index (PI) and the surgical pleth index (SPI)—to see which one detects a successful caudal block faster in children aged 1 to 6 years having lower belly surgery. A caudal block is a numbing injection near the tailbone that helps control pain after surgery. The goal is to find a reliable way to confirm the block is working while the child is under general anesthesia.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- caudal block (a regional anesthesia procedure)
- What this could lead to
- If successful, this could help anesthesiologists quickly confirm that a caudal block is working in children, reducing reliance on less reliable signs.
- What could go wrong
- This is a small observational study (40 children), so results may not apply broadly. The monitors' accuracy in children is still unclear.
