19AP68 Strategy for extubation of the difficult airway: A protocol and table of airway devices F. Llobell, P. Marzal, M. Echeverri, L. Hoke, Y. Bryan Anesthesiology and Critical Care, Hospital G.U. Marina Alta, Denia, Alicante, Spain Background and Goal of Study: Intubation algorithms for patients with difficult airways (DA) and extubation guidelines in ICU patients exist (1). Extubation of patients with difficult airways is less standardized despite many complications reported after extubation (2, 3). We created an extubation protocol in patients with a known difficult airway consisting of an airway device table used to bridge extubation. We present our experience with this protocol and table for extubating patients with difficult airways. Materials and Methods: We created a table for extubation of the difficult airway divided into 4 quadrants according to function (see Figure 1). By moving clockwise, the four quadrants are; 1) oral and nasal airways, LMA s to improve oxygenation and ventilation; 2) airway exchange catheters, stylets, and guidewires to delay extubation or assist in reintubation; 3) FFB and Bonfils to visualize glottis; 4) cricothyrotomy kit and TTJV for surgical access.
Results and Discussion: We used the algorithm and table for extubation in 4 patients (see Table 1). No patients experienced any complications and the mean time to extubation was 58 (range of 30, 90) minutes. Table 1 Case Age ID (years)

Conclusion(s): The protocol and table during extubations enhanced the safety in patients with difficult airways. The availability of devices at extubation prepares one for different airway scenarios. Further research is required regarding extubation protocols in patients with difficult airways.
