A single center, prospective, observational study
Research period: From February 1, 2017 to February 28, 2019
Estimated number of cases: 3,000 cases
Estimation of a sample size: We estimated failure rates of 1% for the first intubation. We calculated 3,000 cases as a sample size based on 95% confident interval of 1%.
Key inclusion criteria:
All patients undergoing elective surgeries and orotracheal intubation performed by anesthesiologists or non-anethesiologists supervised by anesthesiologists
Key exclusion criteria:
Patients younger than 20 years-old
Patients undergoing awake intubation
Patients undergoing slow induction or rapid sequence induction
Patients undergoing tracheotomy
Patients who have already received tracheotomy
Patients undergoing tracheal intubation without neuromuscular blocking agents
