Which blade size works best for intubation? large study seeks answers
NCT ID NCT06232837
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at over 3,000 adults having surgery to see which size of Macintosh blade (a tool used to guide a breathing tube into the windpipe) works best. The goal was to find out if blade size affects how often the tube goes in on the first try and how often serious problems like low oxygen or low blood pressure occur. The results could help doctors choose the right blade size for safer intubation.
