About

This study evaluates the risk factors for difficult tracheal intubation in in obstructive sleep apnea hypopnea syndrome(OSAHS) patients undergoing uvulo-palato-pharyngoplast(UPPP)

Full description

OSAHS patients are high risk group of difficult tracheal intubation. In clinical application, unexpected difficult tracheal intubation is not rare. Difficult airway is a significant problem to these patients and the physicans in terms of mortality and morbidity.

This study collects risk factors as physical examinations（including modified Mallampati grade, neck circumference, lateral clinical craniofacial assessment and body mass index ,BMI）, Stopbang scores, polysommographic parameters (including apnea-hypopnea index, AHI and lowest SpO2, LSpO2), and special radiographic parameters in head and neck region. By using statistics method, predictive model to manage risks would be established.

Enrollment: 200 estimated patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers
