SummaryIn a randomised crossover study, we compared times and success rates for tracheal placement of a fibrescope and railroading of a tracheal tube through the classic laryngeal mask airway by anaesthetists with limited experience in fibreoptic intubation (trainees) and those who were experts. Thirty-two patients, 32 trainees and three experts took part. The median (IQR [range]) times to fibrescope placement for trainees and experts were 21 (18-30 [12-58]) s and 17 (14-24 [9-55]) s, respectively (95% CI for the difference 2-8 s; p = 0.023). There were no significant differences between trainees and experts in the times to placement of the laryngeal mask airway (41 (33-47 [31-105]) s and 36 (33-43 [30-52]) s, respectively; p = 0.24), railroading times (43 (40-58 [33-87]) s and 44 (38-57 [31-83]) s, respectively; p = 0.96) and total intubation time (114 (97-127 [80-213]) s and 95 (89-116 [74-139]) s, respectively; p = 0.13). There was no significant difference in the number of attempts needed for successful placement of the fibrescope (p = 0.12) and railroading the tracheal tube (p = 0.22). The differences between experts and trainees when using fibrescope assisted intubation via the classic laryngeal mask airway were not clinically important.
