The goal of this prospective observational study is to test combination of STOP-Bang score and factors predicting difficult intubation can improve accuracy of prediction difficult mask ventilation in obese patients that undergoing to elective surgery under general anesthesia.
The main question[s] it aims to answer are:
Participants who undergoing to elective surgery under general anesthesia will
If there is a comparison group:
Researchers will compare obese patients with/without high STOP bang score >=3 point plus factor predicting difficult intubation (Mallampati grade 3-4, Neck circumference > 42 cm, Thyromental distance < 6 cm)to prediction difficult mask ventilation

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Difficult mask ventilation | Difficult Mask Ventilation Grading (by Han et al.) Grade 1 mask ventilation can be easily performed by a single person Grade 2 requires the use of equipment such as an oropharyngeal airway Grade 3 necessitates the involvement of two or more personnel for mask ventilation or increasing oxygen flow Grade 4 indicates an inability to perform mask ventilation If the grade is ≥ 3, it signifies difficult mask ventilation |
| |
| non-difficult mask ventilation | Difficult Mask Ventilation Grading (by Han et al.) Grade 1 mask ventilation can be easily performed by a single person Grade 2 requires the use of equipment such as an oropharyngeal airway Grade 3 necessitates the involvement of two or more personnel for mask ventilation or increasing oxygen flow Grade 4 indicates an inability to perform mask ventilation If the grade is < 3, it signifies non-difficult mask ventilation |
