Abstract:
This is a brief report evaluating a new single use endotracheal tube introducer (METTI) which has a soft curved atraumatic tip. The introducer was tried in 44 patients, whose direct laryngoscopic view was simulated to Cormack IIIb score, and in six patients with real Cormack III score. The overall success rate of railroading of the tracheal tube over the introducer was 94% from the first attempt.
