研究概览
简要总结
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 .
详细描述
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.

结局指标
主要结局
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.
时间窗: After enrolment of the patient and before intubation
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.
次要结局
- To find the complications associated with nasal intubations that were performed after assessing the radiological images.(At the time of intubation)
