简要总结
To assess accuracy of NC/TM distance ratio in terms of sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV) for predicting difficult intubation in obese patient with Intubation difficulty score (IDS) as gold standard.
详细描述
At Preanaesthesia clinic patients , neck circumference to Thyromental distance ratios of obese patients with BMI >30Kg/m2 will be calculated and patients will be divided into two groups on the basis of Nc/TMD ratio as anticipated easy intubation ( NC/TMD<5) And anticipated difficult intubation ( NC/TMD ≥5).
Intra-operatively, patients Intubation difficulty scale score will calculated and the data obtained from IDS score will be compared with NC/TMD ratio as a predictor of difficult Intubation and diagnostic accuracy of NC/TMD as a reliable indicator of difficult intubation in obese patients will be calculated by statistical analysis.

结局指标
主要结局
Predictability of difficult airway
时间窗: During anaesthesia induction
At the preanaesthetic examination neck circumference to thyromental distance ratio will be caculated in obese patients with BMI ≥ 30KG/m2 and the predictability of difficult airway will be evaluated by statistical analysis
