Either uses two different endotracheal tubes to pass the nasal cavity and to compare the effects on the secretion and bleeding volume of patients during intubation to facilitate nasotracheal tube advancement.


  1. Assess the patient's airway before intubation. EKG, blood pressure and SPO2 are monitored during the process.
  2. Randomly divided into two groupsHenan Tuoren Endotracheal Tube and Smiths Portex Tracheal tubes.
  3. Sedation processGive Fentanyl 1 ug/kg according to the patient's weight via IV.
  4. Give 1.5ml of Lidocaine without Epinephrine and 0.5ml of Lidocaine with Epinephrine to reduce intranasal bleeding.
  5. Sedative injectiongive Fentanyl 1ug/kg + Thiamylal 5mg/kg + Rocuronium 1mg/kg
  6. Anesthesia intubation inducerPropofol 1mg/kg
  7. Intubation
  8. Record the bleeding of the oropharyngeal and nasal mucosaintubation timeIntubation Difficult Scale (IDS score) and number of intubations during intubation.
  9. Record oropharynxnostril and oropharynx bleeding in 3 minutes after completion of intubation.
  10. Evaluate the patient's sore throat, hoarse voice, dysphagia, nasal congestion, nose bleeding, and nasal pain every other day.
