How common is difficult airway and complications of intubation outside the OR?
In the ICU (136 Intubations) [1]
- 13.2% of all intubations required ≥3 attempts
- 6.6% of expert/faculty intubations required ≥3 attempts
- 10.3% of all intubations required > 10 minutes
- Overall risk of complications in 39% of intubations
- Severe Hypoxemia (19.1%)
- Severe Hypotension (9.6%)
- Esophageal Intubation (7.4%)
- Overall ICU and hospital mortality 15.4% and 29.4% respectively (p = 0.46 and 0.25 respectively)
Conclusion: Over 1/3 of intubations done in the ICU had complications associated with them in this study
On the Wards (150 Intubations) [2]
- 76% 1st pass intubation rate overall
- Complication rates: 27% emergent intubation vs 22% elective intubation
- Biggest complications:
- >2 attempts in 9%
- Esophageal Intubation in 9%
- No survival difference between emergent intubation (59%) vs elective intubation (50%) [p = 0.46]
- No survival difference between patients with complications (48%) vs no complications (54%) [p = 0.63]
Conclusion: Emergent intubation on the inpatient wards had a nearly 1/3 complication rate in this study
In the Emergency Department (280 Intubations) [3]
- 83% 1st pass intubation rate overall
- 1st pass intubation rate 81% for VL vs 83% for DL (p = 0.59)
- Intubation failure rate 14% for VL vs 8% for DL (p = 0.12)
- Median time to successful intubation 42 seconds for VL vs 30 seconds for DL (p <0.01)
Does video laryngoscopy increase success rate of emergent tracheal intubation vs direct laryngoscopy in untrained medical personnel? [4]
- Overall success rate GlideScope technique (93%) vs Direct laryngoscopy technique (51%) [P < 0.01]
- Time for intubation: 89 +/- 35 s for direct laryngoscopy vs 63 +/- 30 s for GlideScope technique (P < 0.01)
Conclusion: In untrained medical personal, VL had higher success rate of intubation and quicker time to intubation vs DL
How important is successful 1st pass intubation in care of patients? [5]
- First attempt success = 14.2% complication rate
- Two attempts = 47.2% complication rate
- Three attempts = 63.6% complication rate
- Four or more attempts = 70.6% complication rate
- Most common complication was oxygen desaturation
Clinical Take Home Point: As the number of attempts at intubation increases, so does the incidence of complications

How Should Trainees Be Trained to Intubate?
Should Video Laryngoscopy Be the 1st Attempt Best Practice For Intubation?
Results from Voting: Its a draw!!! What this tells us is that it doesn’t matter what your plan A is for intubation, but you should also be good at a plan B and plan C so that you can work in any environment!!!
