This research aims to investigate potential variations in the success rate and occurrence of complications during nasogastric tube insertion between Difficult and Easy Airway Patients.

Patients who are scheduled for surgery for any reason and who will receive general anesthesia requiring perioperative nasogastric tube insertion will be included in the study. Two groups will be formed, the easy airway group and the difficult airway group. The main aim is to investigate whether there is a difference between the groups in terms of the success of insertion of the nasogastric tube (first attempt, second attempt etc.) and the duration of insertion. Investigating the differences between the groups in terms of complications such as bleeding, twisting in the mouth, kinking, and going to the trachea is determined as a secondary aim. At the end of the study, determining the correlation between the failure of nasogastric tube insertion and difficult airway parameters is planned as another secondary goal.

Inclusion Criteria: Patients who are scheduled for surgery for any reason and who will receive general anesthesia requiring perioperative nasogastric tube insertion will be included in the study.
