【摘要】Background: Endotracheal intubation (ETI) is a life-saving procedure taught to medical students. We examined the influence of the order of teaching ETI through direct laryngoscopy (DL) and video laryngoscopy (VL) on learning by measuring the intubation time and learning curve of trainees, in order to explore ways to improve ETI performance.Methods: Twenty trainees were randomly divided into 2 groups. In the DL-first group, trainees used DL to perform ETI 10 times and then used VL 10 times, while the order was reversed in the VL-first group. Intubation time, number of intubation attempts, the Cormack-Lehane (CL) classification, and adverse events were recorded. The primary outcome was the cumulative summation (CUSUM). The CUSUM equation is defined as (Equation is included in full-text article.), where ct is the cumulative sum.Results: ETI was attempted on 400 patients. The difference in the mean times for the first 10 intubations between the 2 groups was not significant (P > .05). Mean intubation time for second series in the DL-first group was significantly shorter than that of the first series (P .05). The mean intubation time in the second series of the DL-first group was shorter than for the first series of the VL-first group (P .05). Eighteen attempts were required to achieve an 80% intubation success rate for the DL-first group, while more than 20 attempts were required for the trainees in the VL-first group.Conclusion: We consider that teaching trainees DL for tracheal intubation first.Clinical Trial Number: ChiCTR-OOR-16008364.
