I am in my first few months of CRNA school and was having a hard time visualizing the difference in blade placement between MAC and Miller blades. Your video is the only video on youtube I found after, honestly, hours that explained it to where I finally understood it. Thank you so much for posting this!
Nice. What are the special situations you would want to go for straight blade in adults rather than the McIntosh blades which are regularly used with good success rates! Please share your knowledge.
There isn't situation specific change in blade selection. Use the blade you are most proficient and have the most experience for your first attempt. If you employed Mac blade or standard geometry video laryngoscope (shaped as Mac) for years and have good proficiency, it would be foolish to switch to another blade because of perceived situation. Use the one you are most proficient in for your first attempt.
Most people would never use the miller nowadays. Historically when other intubation aids didn't exist you would change blades after failing with your first choice one. Now you would switch to an SGA, a video laryngoscope or a flexible bronchoscope
