Abstract

We compared awake fibreoptic intubation with awake intubation using the Pentax Airway Scope(®) in 40 adult patients. Sedation was achieved using a target-controlled remifentanil infusion of 1-5 ng.ml(-1) and midazolam. The airway was anaesthetised with lidocaine spray and gargle. The total procedure time - a composite of sedation time, topical anaesthesia time and intubation time - was recorded. The operator's impression of the ease of the procedure and the patients' reported comfort were recorded on a 0-100 mm visual analogue scale. The median (IQR [range]) for total procedure time was 900 (739-1059 [616-1215]) s with the fibrescope and 651 (601-720 [498-900]) s with the Pentax Airway Scope (p = 0.0001). The median (IQR [range]) intubation time was 420 (283-480 [120-608]) s with the fibrescope and 183 (144-220 [107-420]) s with the Pentax Airway Scope (p = 0.0002). The median (IQR [range]) visual analogue scores for the operator's ease of intubation for the fibrescope and Pentax Airway Scope were 83.6 (72.0-98.0 [49.0-100.0]) and 86.8 (84.0-91.0 [61.0-100.0]), respectively (p = 0.3507). The median (IQR [range]) visual analogue score for patient comfort was 85.5 (81.0-97.0 [69.0-100.0]) and 79.4 (74.0-85.0 [59.0-100.0]) for the fibrescope and Pentax Airway Scope, respectively (p = 0.06). Total procedure time was significantly shorter with the Pentax Airway Scope compared with the fibrescope, with no difference in procedure difficulty or patient discomfort.
