Radiological Images for Nasotracheal Tube Size Estimation

Rajiv Gandhi Cancer Institute & Research Center, India100 enrolled

Overview

This trial is planned to estimate the size of nasotracheal tube (NTT) by calculating the diameter of both nasal cavity in radiological images of nose (CT scan/MRI) at the level below the inferior turbinate and floor of nose in coronal planes. Smallest diameter will be considered to calculate the outer diameter of NTT, hence the size .

The planned trial will estimate the size of nasotracheal tube (NTT) by calculating the diameter of both nasal cavity in radiological images of nose (CT scan/MRI) at the level below the inferior turbinate and floor of nose at different levels in coronal planes. Smallest diameter will be considered to calculate the outer diameter of NTT, hence the size. The side of nasotracheal intubation will be decided after view the radiological images and the estimated size of NTT will be used. Finally the ease of intubation and complications will be recorded.

Outcomes

Primary Outcomes

Successful nasal intubation by selecting the correct size of nasotracheal tube estimated by measuring the diameter of nasal cavity in coronal section just below the inferior turbinate in radiological images.

The diameter of both nasal cavities in coronal section of CT/MRI will be calculated at the level just below the inferior turbinate in anterior nasal cavity when inferior turbinates just appeared in the radiological image, than at level of maxillary sinus and just before cohanal opening in radiological images. Minimal diameter will be used to estimate the size of nasotracheal tube before intubation.The images will also be used to select the side of nasal intubation after ruling out any nasal pathology like DNS, Spurs and marked turbinate hypretrophy.

Time frame: After enrolment of the patient and before intubation

Secondary Outcomes

To find the complications associated with nasal intubations that were performed after assessing the radiological images.

The radiological images will be studied prior to intubation, the appropriate size of the nasotracheal tube will be selected and after ruling out any nasal pathology like DNS , spurs, concha bullosa side of nasal intubation will be decided.

Time frame: At the time of intubation
