In this study, investigators will research the types and incidence rates of airway complications seen in the perioperative period during airway management. In addition, unlike the literature, the relationship between the airway equipment used and perioperative airway complications will be investigated.

Complications related to airway management rarely occur in the operating room; however, these complications can lead to life-threatening situations. There are many studies on the types and incidence rates of airway management complications in the perioperative period. However, although the types and incidence rates of airway complications have been investigated in these studies, the effect of airway equipment used in airway management on complications has not been investigated. There are many equipment used in airway management. Laryngoscopes, face masks, oral airway devices and many assistant airway management devices are used as basic equipment. Different airway equipment may be used in each center in each case. There is no standard between centers in this regard.

In this study, investigators will primarily research the types and incidence rates of airway complications seen in the perioperative period during airway management similar to the existing literature. In addition, unlike the literature, the relationship between the airway equipment used and perioperative airway complications will be investigated.

Inclusion Criteria:

1. Patients between the ages of 18 and 75.
2. Patients who will undergo elective surgery.
3. Patients to be operated under general anesthesia.
4. Patients without difficult airway markers

Exclusion Criteria:

1. Patients to be operated with emergency surgical indication.
2. Patients to be operated with regional anesthesia.
3. Patients with expected difficult airway markers.

The study was prospective and observational. There is no grouping. Oral and written informed consent will be obtained from the patients in the preoperative ward or in the preoperative preparation room of the operating room.

Patients scheduled for elective operation under general anesthesia whose consents were obtained will be included in the study. Airway management techniques and equipment used will not be interfered with.

After the patient's airway management is completed: the following data will be recorded.

• Types of equipment: laryngoscopes, face masks, oral airways, styli, plugs, etc.
• Professional experience of the airway management practitioner (in years).
• If advanced, type of airway complication (bleeding, dental damage, mucosal damage, etc.), number of attempts.
