Summary

This study is testing whether adding different doses of fentanyl to standard spinal anesthesia can improve pain control and recovery after planned C-sections. 63 women will receive one of three fentanyl doses (0, 10, or 20 micrograms) along with bupivacaine and morphine. Researchers will measure pain levels and recovery quality in the first 24 hours after surgery.

What this could mean

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

Active substance
fentanyl
What this could lead to
If successful, this could help doctors choose the best fentanyl dose for spinal anesthesia during C-sections, leading to better pain relief and faster recovery after surgery.
What could go wrong
This is a small, early-phase study (63 participants) at a single hospital, so results may not apply to everyone. Adding fentanyl may increase side effects like itching or nausea.
