The aim of our study is to observationally examine our unexpected difficult airway incidence and intervention times. In addition, it is aimed to discuss the clinical effect of a team specialized in airway intervention intervening in cases by call on the success of airway intervention. In this discussion, it is aimed to use the opinion-opposition method.
Initiation of Airway Code: The Role of the Airway Team in Unexpected Difficult Airways
The incidence of difficult airway is approximately 1 in 1000 cases and poses a significant perioperative risk to patients. Various classifications, guidelines, and approaches have been developed to identify patients with difficult airways. However, even the most well-known classifications are not 100% successful in predicting difficult airways. Consequently, some unexpected difficult airway cases are encountered, and their management continues to be a subject of new research in the literature.
In situations involving difficult airways, having the same team respond to every case may pose a potential obstacle to the distribution of experience and responsibilities among other clinical staff. However, it is undeniable that experienced anesthetists are more successful in airway management, and the importance of airway-related training cannot be overstated. Similar to the code blue protocol used during cardiac arrests, the intervention of a trained external team in crisis situations, utilizing familiar equipment and applying data from previous cases for quality improvement, can provide significant benefits in airway management akin to those seen in cardiac arrests. This approach could also potentially enhance patient safety in internal medicine and surgical wards, as well as in certain intensive care units, where familiarity with airway management is limited.
This study aims to discuss the positive and negative impacts of the airway teams intervention in unexpected difficult airway situations within the operating room, using a pro-con debate method.

Inclusion Criteria:
Exclusion Criteria:
- 1. Expected difficult airway patients (mallampati 3-4) and other patients with high difficult airway scores will not be included in the study.
2. Patients with difficult airway conditions but who will be awakened by giving up endotracheal intubation will not be included in the study.

Unexpected difficult airway patients will be included in our study. These patients should need perioperative endotracheal intubation without signs of difficult airway in their airway evaluation scores, and the patients should be intervened by the anesthesiologists themselves or the airway team.
