Could lying on your stomach ease a deadly sickle cell complication?
NCT ID NCT06698120
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether awake prone positioning (lying on the stomach while awake) can help sickle cell patients with severe acute chest syndrome in the ICU. The approach aims to improve oxygen levels and breathing by evening out air flow in the lungs. Fifteen adults will be enrolled to see if the procedure is safe and effective.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- awake prone positioning (a procedure where patients lie on their stomach while awake to help breathing)
- What this could lead to
- If it works, this could offer a simple, drug-free way to improve oxygen levels and reduce breathing effort during acute chest syndrome.
- What could go wrong
- This is a very small early study with only 15 participants, so results may not apply widely. The procedure may be uncomfortable or poorly tolerated.
