The success rates of direct endotracheal intubation comparing between trained by using direct versus video laryngoscopy in inexperienced medical students Success rate of endotracheal intubation

Abstract

Placement of an endotracheal tube is a fundamental procedure in airway management, but novice providers face an increased risk of failure and complications. While using a video laryngoscope (VL) has been shown to enhance success rates, limited evidence exists on whether training with a VL improves success when the procedure is performed with a direct laryngoscope (DL). Objectives This prospective randomized controlled trial aimed to compare the success rates of novice medical students in endotracheal intubation using a DL after training with either VL or traditional training with DL Methods One hundred and thirty novice medical students were randomly assigned to two groups: the VL group (n=65) and the DL group (n=65). After a single training session with their assigned equipment, all students performed one intubation attempt on a manikin using a DL. Results The study found no significant difference in the first-attempt success rate between the VL and DL groups (98.0% vs. 97.7%, p=1.000) However, the VL group demonstrated better full laryngeal visibility (Grade 1 view: 29.4% vs. 27.3%, p=0.030) and higher satisfaction levels (88.2% vs. 72.7%, p=0.039). There were no significant differences in intubation time or dental click events. Conclusions In conclusion, training with a VL provides a clearer visualization of laryngeal structures and enhances satisfaction among medical students when compared to traditional DL training.
