Head-Down tilt may stop blood pressure crash during anesthesia in seniors
NCT ID NCT06968091
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tested whether tilting elderly patients head-down at a 10-degree angle during the start of anesthesia could prevent dangerously low blood pressure. Researchers compared this position to lying flat in 168 patients aged 65-90 having abdominal surgery. The main goal was to see if the head-down tilt reduced the time blood pressure stayed too low in the first 15 minutes after anesthesia.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Trendelenburg positioning (tilting the body head-down at a 10-degree angle)
What this could lead to
If effective, this simple head-down tilt could become a standard, low-cost way to prevent dangerous drops in blood pressure when elderly patients are put to sleep for surgery.
What could go wrong
This is a completed, moderate-sized trial, but the effect may be modest or not apply to all elderly patients. The head-down position also has risks (e.g., breathing or brain pressure issues) that limit who can use it.
