A study to evaluate the optimal insertion length of tracheal tube in orotracheal intubation in Indian adults.
Atotal of 100 patients of either sex, belonging to American society of Anaesthesiologists class I and II (aged 20–60) posted for surgery under general anaesthesia &requiring endotracheal intubation were included in this study. Orotracheal intubation was achieved with cuffed, endotracheal tube (ETT) 7.0 mm internal diameter (ID) for female patients and 8.0 mm ID for males. ETT was positioned, so as to keep the black mark proximal to cuff, at the level of vocal cords. The length of tube at the right corner of mouth was noted. Fiberoptic bronchoscope was inserted through the tube just past the carina and slowly withdrawn to the point where we could just see the carina. Fiberoptic bronchoscope was marked externally at this point, from this length we deducted the tube length along with adapter for each patient to get the distance between the tube tip and carina.
In female patients 96% (n=48) had depth of insertion (DOI) between 17.5–20cm. In male patients 92% (n=46) had DOI >20cm (2023). Eighty percent patients both male and female had endotracheal tube tip to carina Distance (TCD) >2cm.
DOI of tracheal tube in orotracheal intubation in Indian adults is shorter than mentioned in the most of European studies.
