Abstract:
OBJECTIVE:To build up a simple and effective comprehensive system for predicting difficult laryngeal exposure under suspension laryngoscopy.
METHOD:One hundred and twenty cases of laryngeal tubor were selected. Using Logistic regression method to analyse relative factors, including weight, height, BMI, neck girth, neck upward degree, upper-lower incisor teeth distance, thyroid-mentum distance, thyroid-sternum distance, Mallampati test, Yamamoto test and Upper lip bite test. Build data-base to construct a comprehensive system for predicting difficult laryngeal exposure under suspension laryngoscopy.
RESULT:The relative factors of difficult laryngeal exposure were BMI, neck girth, upper-lower incisor teeth distance, neck upward degree, thyroid-mentum distance, Mallampati test and Yamamoto test (P < 0.05). To build up a comprehensive system for predicting difficult laryngeal exposure under suspension laryngoscopy. The predicting standards included the seven relative factors, each factor has 1 score, 2 score, 3 score. Higher score means more risk. Eight score was designed as minimum, under the premise,the sensibility, misdiagnosis rate, missed misdiagnosis rate, specificity of the experiment were 95.5%, 5.3%, 4.5%, 94.7%.
CONCLUSION:The comprehesive system is an effective method for predicting difficult intubation. It can help to identify difficult cases according to the results of this predicting system.
