NCT ID NCT07697651
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This study looks at whether spinal anesthesia used during planned cesarean deliveries can cause temporary hearing loss. Researchers will test women's hearing before and after the procedure using a standard hearing test. They will also track headaches that can occur after spinal anesthesia to see if hearing changes are linked. The goal is to better understand this possible side effect.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If hearing changes are found, it could help doctors better inform patients about temporary hearing loss after spinal anesthesia.
- What could go wrong
- This is a small observational study, so it cannot prove cause and effect. Results may not apply to all women or other types of surgery.
