Brief summary
Difficult intubation is the situation that anesthesiologists don't want to face. Sometimes, difficult intubation affects the patient's oxygen saturation and harms for life. Many studies try to identify the predictors of difficult airway in pediatric patients. In this study, the investigator team want to identify the predictors of difficult intubation in pediatric patient by using additional parameters which are including hyomental distance, sternomental distance, neck circumference, ratio of hyomental distance to Thyromental distance, ratio of hyomental distance to sternomental distance, ratio of height to neck circumference, ratio of height to thyromental distance, Ratio of height to hyomental distance.
Detailed description
After approval from the instution's Ethics Committee, a prospective cohort study was conducted in pediatric patients aged between 1-8 years, ASA physical status I-II who were scheduled for general anesthesia in elective surgery. One day prior surgery, Children and their parents were invited to be participated in the study by using verbal invitation and flyer. After giving consent, Addition physical examinations which are the measurements of hyomental distance, sternomental distance and neck circumference were done by two independent investigators. The ratio of hyomental distance to Thyromental distance, ratio of hyomental distance to sternomental distance, ratio of height to neck circumference, ratio of height to thyromental distance and ratio of height to hyomental distance. At the day of surgery, standard general anesthesia (balance technique) was done. The child was intubated using aged appropriated laryngoscope by general anesthesiologist. Cormack-Lehane grading was used to identify the difficult intubation. (grade III and IV). Data will be analyzed by R Program. The statistically significance was set as P\<0.05. Multivariate Logistic Regression analysis will be used to identify the predictors of difficult intubation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The predictors of difficult airway | up to 1 minutes after starting the process of intubation | Laryngoscopic view was determined by using Cormack-Lehane grading (grade III-IV) were used to identify difficult intubation situation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The correlation between time spent for intubation and laryngoscopic view | up to 10 minutes after starting the process of intubation | Laryngoscopic view was determined by using Cormack-Lehane grading (grade III-IV) were used to identify difficult intubation situation |
