It may seem shocking, but this study found intubation of the esophagus does not improve oxygenation.  Seriously, the conclusions were that desaturation was more common if: respiratory indication for intubation, esophageal intubation, and duration > 30 seconds of laryngoscopy (both individual and cumulative).

Conclusions: 1. Fasting is not required (Level B). 2. Capnography is helpful (Level B). 3. You don't need two physicians in the room, but your hospital may require it (Level C). 4. You can use pretty much any drug you want, specifically ketamine (A), propofol (A), "ketofol" (B), etomidate (B, C in kids), dexmedetomidine (no evidence), alfentanil (C), and remifentanil (no evidence) (Levels A-C).

Emergency physician intubation is highly successful, 99.4%. Video laryngoscopy use and rocuronium vs. succinylcholine use have increased dramatically.

Optimizing positioning, preoxygenation, PEEP, and passive apneic oxygenation are the keys to prevent desats.

If you are fat, old, have a beard, and snore (i.e. you look like Santa Claus), modify the only risk factor you can and at least shave off your beard. "Body mass index of 30 kg/m or greater, a beard, Mallampati classification III or IV, age of 57 yr or older, severely limited jaw protrusion, and snoring were identified as independent predictors for grade 3 MV. Snoring and thyromental distance of less than 6 cm were independent predictors for grade 4 MV. Limited or severely limited mandibular protrusion, abnormal neck anatomy, sleep apnea, snoring, and body mass index of 30 kg/m or greater were independent predictors of grade 3 or 4 MV and difficult intubation."
