Two common drugs put to the test for safer brain surgery intubation
NCT ID NCT07820540
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Placing a breathing tube during general anesthesia can briefly raise heart rate, blood pressure, and pressure inside the head. This matters most for people having brain surgery. Researchers are testing whether intravenous dexmedetomidine or lidocaine, compared with a saline placebo, can blunt those changes. They will measure the optic nerve sheath with ultrasound as an indirect sign of brain pressure in 90 adults scheduled for elective brain surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dexmedetomidine, lidocaine, or saline given intravenously before anesthesia
- What this could lead to
- If dexmedetomidine or lidocaine works, doctors could use it to keep brain pressure steadier when placing a breathing tube in people having brain surgery.
- What could go wrong
- This is a small, single-center study in one type of brain surgery. The eye measurement is an indirect sign of brain pressure, so the results may not apply to other patients or surgeries.
