New spinal technique may prevent blood pressure drops during C-Sections
NCT ID NCT07327866
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two ways of giving spinal anesthesia for planned C-sections: the standard single injection versus a sequential (two-part) injection. The goal is to see if the sequential method reduces the chance of a sudden drop in blood pressure, a common and risky side effect. About 94 women aged 18-45 will take part, and their blood pressure will be monitored closely after the injection.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bupivacaine and fentanyl (spinal anesthetic)
- What this could lead to
- If it works, this could lead to a safer spinal anesthesia technique for C-sections, reducing the risk of dangerous blood pressure drops.
- What could go wrong
- This is a small, early-phase trial with only 94 participants, so results may not apply to all patients. The sequential method may also be more complex to perform.
