Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1)To compare the percent positions of ETT tips positioned too low (3 cm above the carina) or too high (5 cm above the carina) using the four methods and to determine and compare the percentage of subjects in whom TT-tip comes in safe range of placement of 3-5 cm above the carina. 2)To know and compare the distance of proximal rim of TT cuff from the vocal cords in the four methods and to compare the percentage of subjects in whom the position of TT cuff is in the safe range of 1.5-2.5 cm below vocal cords. Timepoint: immediately | — |
Secondary
| Measure | Time frame |
|---|---|
| 1)To determine and compare the distance between upper incisors to TT tip (depth of insertion of tracheal tube). 2)To compare the upper incisors to carina distance. 3)To determine and compare the vocal cord-carina distance. 4)To determine and compare tracheal length. 5)To estimate and compare the distances after bringing the TT tip and/or cuff at the recommended and safe FOB verified positions. 6)To calculate the correlation coefficients tests of surface anatomy airway measurements with airway distances/lengths (cm) Timepoint: immediately | — |
