Study population: Calculation by Diagnotic test that used sensitivity and Specificity of the precedent journal "Accuracy of STOP-Bang Questionnaire in Predicting Difficult Mask Ventilation: An Observational Study by Marium N. Khan , Aliya Ahmed" total population 278 patients

Brief summary: 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:

* Can combination of STOP-Bang score and factors predicting difficult intubation improve accuracy of prediction difficult mask ventilation in obese patients?
* Study about complication after endotracheal tube insertion in obese patients that undergoing to elective surgery under general anesthesia.

Participants who undergoing to elective surgery under general anesthesia will

* Routine preoperative evaluation and ask about STOP bang questions, evaluate neck circumference, Mallampati grade,Thyromental distance (That routine physical examination for anesthetic care pre-operation)
* In operation room, patients will be inducted anesthesia by anesthesiologist (step routine for general anesthesia),observe difficult mask ventilation grading before intubate endotracheal tube and complication after endotracheal tube insertion.

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


Eligibility criteria: Inclusion Criteria:

* BMI ≥ 25 kg/m2
* Age \> 18 years old
* undergoing elective surgery under general anesthesia with endotracheal intubation

Exclusion Criteria:

* History of difficult mask and intubation
* Maxillofacial or upper airway malformation
* History of C-spine disease such as trauma, degeneration
* Pregnancy
* Rapid sequence induction technique

Primary outcomes:
measure: Difficult mask ventilation
timeFrame: After the induction of general anesthesia, observe the assisted mask ventilation. End the collection of the primary outcome before endotracheal tube intubation.
Secondary outcomes:
measure: Resipiratory complication
timeFrame: during mask ventilation until the completion of intubation.
Other outcomes:
