About

Based on the evaluation of preoperative physical indicators and radiologic indicators of cervical surgery, this study puts forward effective indicators for predicting difficult airway before operation, and establishes a comprehensive decision support system of difficult airway evaluation, so as to provide a theoretical basis for the early warning of difficult airway before cervical spondylosis surgery.

Full description

In the past, the evaluation of difficult airway mainly depended on physical indicators, but the internal structure of airway could not be found by appearance inspection. Therefore, unexpected emergency airway often appeared in clinical work, which seriously affected medical safety. In this study, the specific mechanism of difficult laryngoscopy in patients undergoing cervical spondylosis surgery is clarified by the combination of the physical indicators and radiologic indicators. On this basis, we will establish the preoperative airway evaluation system for cervical spondylosis surgery, optimize the standardized process of preoperative airway evaluation, and accurately screen out high-risk patients.
