Design outcomes

Primary

MeasureTime frame
Evaluate and compare the accuracy of the formula based on height (Depth (cm)=4 +0.1 height(cm) and Middle finger length-based formula (Depth of insertion of oral tracheal tube= 3 × middle finger length)Timepoint: During orotracheal intubation

Secondary

MeasureTime frame
To evaluate relationship between height of the patient and tracheal lengthTimepoint: After orotracheal intubation
