When difficult airway/intubation occurs in the OR the anesthesiologist needs rescue techniques and equipment. The algorithms about management of the difficult airway don't provide adequate data. In current study researchers aim to determine most preferred rescue techniques and success rate of the chosen technique.

In anesthesia setting Failed tracheal intubation, leading mortality and morbidity is very important. In operation room when a Difficult intubation occured with concurrent difficult mask ventilation rapid manipulation and quick decision are lifesaving. The Presence of assistant medical personnel or rescue equipment and crisis management of physician is crucial. In anesthesia practice when difficult airway occured rescue techniques are used to facilitate the intubation but difficult airway algorithms do not provide adequate information which rescue technique should be used in a state of emergency in OR thereby current trial was designed to determine which rescue techniques are used in everyday practice to manage difficult intubation, success and complication rates of chosen techniques.

Aim of the study

1. Most preferred rescue technique of the anesthesiologist When a difficult airway or difficult intubation ventilation occured
2. success rate of the chosen technique
3. Incidence of possible complications
4. Most preferred rescue technique of the anesthesiologist on presence of the difficult mask ventilation
