I'm saying that SIX failed airway attempts is piss poor patient care anyway you slice it. Do you think that cramming a combi tube in on attempt number 3 is going to deliver any different results than the first 2 failed attempts? If your answer is yes, you need retraining. (Do you think trauma from repeated CombiTube insertion attempts might have been what "packed the airway full of blood..."?)
As I said, managing a messy airway is difficult, but certainly not impossible. Did they truly AGGRESSIVELY, CONTINUOUSLY suction? I don't know, and neither do you. Can this person place an OG/NG tube? However, from the description, they seemed WAY more focused on obtaining an advanced airway than actually MANAGING the patient. An airway course, as I mentioned, would have taught some triucks like using a merconium aspirator and how to suction a misplaced tube while leaving it in place.
Did you ever hear the expression, "Blame it on the rain?" Not my fault. The equipment was didn't work. Not my fault, the airway was clogged with puke. Not my fault, the trachea was really anterior. Not my fault, the tube must have moved. Not my fault... and on and on. Guess what? It's the FAULT OF THE PROVIDER. It's our job to manage these patients. Not only the ones with a dry, Class I Mallampati... but the puke filled, difficult to ventilate patients too.
Don't be obtuse. The advise in this thread is take an airway course and own the issue. The OP couldn't manage the airway. It's plain and simple. And you know as well as I do, the agencies that provide continuing education on airway management have statistically higher first pass intubation success rates. Education is the key...
