Educational Pearls:

First-pass success is critical to limit complications from apnea, hypoxia, and airway trauma.

Complication rate for patients intubated on the first pass is 14%
Complication rates increase to 47% after two attempts, 64% after three, and 71% after the fourth attempt

How to improve likelihood of first-pass success:

Use Video laryngoscopy (VL). VL increases chance of first-pass success to 85% from 71%
Use a bougie, especially in patients with anatomically difficult or otherwise obstructed airways. The BEAM study cites a success rate in these patients of 96% with a bougie, compared to 82% without
Use a Checklist mnemonic (SOAPME)

Suction – On, ready, and within reach
Oxygen – Patient is preoxygenated
Adjuncts – Oral/nasal adjuncts and BVM ready
Positioning - Patient positioned properly; consider obesity, using semi-Fowler/head-up positioning
Medications – Rapid sequence intubation (RSI), sedation, vasopressor, and other medications prepared as necessary
Equipment – Laryngoscope (blade), tube, bougie/stylet, syringe, scalpel/cric kit, others ready as necessary
