目的:困难插管气道是麻醉医师极为关注的问题之一。临床用于麻醉前评价患者气道的标准有多种,但使用放射学方法进行困难插管预测的研究较少。该文结合他人研究,新建了一个利用X线头影测量技术进行困难插管预测的系统。方法:全麻前采集成人X线头影测量影像,摄片方法为左向右投照,参数为80kV、10mA,曝光时间2s。头影测量片通过图形数字化仪输入,使用“CASSOS 2001”计算机X线头影测量软件进行测量。结果:可测得软硬组织、气道间隙、舌骨等22项指标。结论:该系统从理论上可利用X线大影测量技术实现困难插管的预测,但其实用性尚需进一步研究。
OBJECTIVE: Difficult intubation of the airway is one of the issues of great concern to anesthesiologists. There are many criteria for clinical evaluation of patients’ airways prior to anesthesia, but few studies have used the radiology method to predict difficult intubation. This article combined with others research, a new system using X-cephalometry measurement of difficult intubation prediction system. Methods: Before the general anesthesia, adult X-ray cephalometric images were taken and the radiographs were taken from left to right. The parameters were 80kV, 10mA and the exposure time was 2s. Cephalometrics were entered via a digitizer and were measured using the “CASSOS 2001” computerized X-cephalometry software. Results: Measured soft and hard tissue, airway clearance, hyoid bone and other 22 indicators. Conclusion: This system can theoretically make the prediction of difficult intubation using X-ray imaging technique, but the practicality needs further study.
