Conditions

Oral Maxillo Facial Surgery

Interventions

After extubation, study subjects will be randomly assigned to receive respiratory management by low-flow oxygen administration (3 L/min: FiO2 0.32) using THIRIVE (LFNC group) or by inhalation of heate

Inclusion criteria

Inclusion criteria: (i) Patients who are judged to require nasotracheal intubation with fiber for oral surgery (ii) Patients who meet any of the following criteria Severe morbid obesity (BMI >35) Difficulty in intubation due to cervical cellulitis Abnormal mandibular morphology (including micrognathia and postoperative jaw deformity) Cervical retroversion disorder such as indirect rheumatism and spondylolisthesis Severe mouth opening disorder that makes the use of a videolaryngoscope impossible. (iii)Patients who are at least 18 years old and less than 85 years old at the time of consent (iv) Patients who have received sufficient explanation of their participation in this study, and who have given written consent of their own free will based on sufficient understanding.

Exclusion criteria

Exclusion criteria: (i)Patients without spontaneous respiration (ii)Patients using artificial nose (iii)Patients who are participating in a clinical trial or other clinical research (iv)Patients who are deemed inappropriate as research subjects by the principal investigator

Design outcomes

Primary

MeasureTime frame
Percentage of hypoxemia (<90%) by SaO2 (arterial blood oxygen saturation)

Secondary

MeasureTime frame
(i)Compare the percentage of hypoxemia (less than 60 mmHg) from PaO2 (arterial blood partial pressure of oxygen) (ii)Compare the rate of occurrence of hypercarbonemia (>50 mmHg) from PaCO2 (arterial blood carbon dioxide partial pressure). (iii)Percentage change in acid-base equilibrium from HCO3- (bicarbonate ion), pH, BE
