No-Drug trick may stop blood pressure drops during surgery in seniors
NCT ID NCT07549152
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether placing elderly patients (ages 65-80) with high blood pressure in a lithotomy (legs-up) position for two minutes before anesthesia could prevent a dangerous drop in blood pressure. Sixty patients were randomly assigned to either the legs-up position or the standard flat position. The researchers monitored blood pressure closely after anesthesia to see if the simple positioning helped maintain stability and reduce the need for emergency medication.
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 it works, this simple, no-cost positioning technique could help prevent low blood pressure during anesthesia in older adults with high blood pressure.
- What could go wrong
- This is a small, completed study with only 60 participants. The results may not apply to all patients or surgeries, and the effect may be modest.
