incidence and severity of Epistaxis
An independent anesthesiologist who did not observe the tube insertion will assess the incidence and severity of epistaxis using a laryngoscope immediately after tube passage through the nasal cavity , four grades to evaluate epistaxis 1- no epistaxis 2- mild epistaxis ,blood apparent on the surface of the tube 3-moderate epistaxis pooling of blood on the posterior pharyngeal wall 4- severe epistaxis , large amount of blood in the pharynx impeding nasotracheal intubation and necessitating urgent orotracheal intubation.
Time frame: immediately after nasotracheal intubation
Histopathology of the endotracheal tube contents after extubation
after extubation the tube contents will be collected in a 5 ml syringe by using sterile swab then tissues will be separated and will be sent for histopathology , the remnant contents will be sent for microscopy , grading the contents as follow 1- secretions only 2- secretions plus blood 3- secretions , blood plus tissues .
Time frame: immediately after extubation
