title: Comparison of airway management during anaesthesia using the laryngeal mask airway CTrach and Glidescope.
abstract: The design of the Laryngeal Mask Airway CTrach combines the fibreoptic viewing capability of the Glidescope and the ability for ventilation of the Fastrach. We conducted a prospective randomised trial comparing the intubation characteristics of the CTrach and Glidescope to investigate the difference in clinical performance for airway management during anaesthesia. One-hundred-and-six patients with normal airways were recruited and randomly assigned to the CTrach or Glidescope group. A standardised anaesthesia and airway management protocol was used. The time to intubation was significantly shorter for the Glidescope compared to the CTrach (43 +/- 22 vs. 73 +/- 36 s, P < 0.001). The success rates of intubation within first and three attempts were significantly higher for Glidescope. There was no apparent difference in complications of device insertion. Our results suggest that during elective management of normal airways, the time to intubation with the Glidescope is significantly shorter than the CTrach. Further studies are required to compare these devices in patients with difficult airways.
