The time required for successful intubation with a stylet guide. Timepoint: Measuring the time required for successful intubation of a patient under general anesthesia. Method of measurement: Stopwatch. The time required for successful intubation with a bougie. Timepoint: Measuring the time required for successful intubation of a patient under general anesthesia. Method of measurement: Stopwatch. Determining the ease of intubation with a stylet guide. Timepoint: Determining the ease of intubation while doing it. Method of measurement: Easy intubation means successful intubation on the first attempt in less than 15 seconds, relatively difficult intubation means successful intubation in 15-30 seconds, and difficult intubation means successful intubation with more than one attempt. (Successful intubation on the second attempt) and failure to perform intubation is called inability to intubate using any of the studied methods. Determining the ease of intubation with a bougie.
