简要总结
Maskventilation remains an essential skill even as new airway equipment continue tobe invented every now and then.It isa simple, non-invasive technique for ventilation used as a primary mode ofproviding anaesthesia for short duration surgery or as a bridge to establish adefinitive airway. Variousclinical parameters are available which help in predicting a difficult maskventilation. Thepredictors of difficult mask ventilation are not routinely documented duringpre-anaesthetic evaluation and if described, it is usually subjective,inconsistent and casually mentioned as easy or difficult . Weplanned this observational study to determine the actual occurrence ofdifficult mask ventilation using capnographicgrading based objective scoring system in clinically predicted anticipateddifficult mask ventilation

结局指标
主要结局
To find association between clinically anticipated and actual difficult mask ventilation using capnographic grading based objective scoring system
时间窗: Baseline, at mask ventilation without NMBD (1 minute), at mask ventilation with NMBD (2 minute)
次要结局
- To compare the objective capnographic score before and after neuromuscular blockade, to internally validate the objective capnographic scoring system with subjective assessment of mask ventilation and to assess the choice of neuromuscular blocking drug in such scenarios.(Baseline, at mask ventilation without NMBD (1 minute), at mask ventilation with NMBD (2 minute))
