• Abstract:

  Introduction: Orotracheal intubation is one of the main life-saving procedures, which is an advanced life support care. In cases of a difficult airway, fiberoptic bronchoscopes are used to facilitate care. Objective: To compare the effectiveness of the procedure with the technique of assisted intubation with a low-cost video equipment compared to the conventional technique under direct vision. Methods: This is a prospective, comparative and quantitative study. Twenty-eight undergraduate medical students with previous theoretical and practical content on the subject were selected. A mini-course and a practical demonstration were presented, leveling the knowledge of the participants. Then, they were divided into two groups. The control group, which performed the procedure using the conventional technique, and the experimental group, which performed the technique with low-cost equipment. They were evaluated through total intubation time; number of attempts to success; number of hits and misses, and the satisfaction of the participants. Results: The intubation time to perform the procedure (p=0.082), as well as the number of attempts (p=0.631) and errors (p=0.773) showed no statistically significant differences between the two scenarios. However, in the evaluation of participants' satisfaction, when asked about better visualization of the oral cavity, the experimental group showed greater satisfaction (p= 0.003). Conclusion: From this, a statistically significant difference was identified regarding the satisfaction of the experimental group, mainly in relation to better visualization of the oral cavity.
