The establishment of functional-morphological and respiration-physiologic diagnosis of the upper respiratory tract failure in the postoperative

术后上呼吸道狭窄和阻塞的发生率很高，因为手术主要发生在它出来的颌部口腔。此外，在全身麻醉剂唤醒后，肌肉松弛药和麻醉剂的作用仍然存在，因此容易出现低回忆状态下的呼吸抑制。尽管在临床上非常重要，但对其发生原因和发生机制的调查发现，术前CT侧头影对比分析是零碎的。此外，目前不明点也比比皆是。本研究通过对X线电视和功能形态分析方法的调整，利用超声成像设备和呼吸关系肌电及呼吸生理测试方法，对阻塞性呼吸疾病包括上呼吸道…的疾病状态进行了全面的分析和诊断。术后呼吸道衰竭较多，其中动态变化较大。此外，还明确了其原因和发生机制，以此为目的。1.在低浓度全麻药以三叉神经为媒介对反射系统的影响上，考查了氯胺酮、咪达唑仑对比例控制系统以三叉神经为媒介的反射系统张口反射(ES1和ES2)的影响。氯胺酮、咪达唑仑不能识别三叉神经对反射系统的影响。同时证明，比例控制系统的下降影响上位中枢水平的反射系统，虽然这种影响不是由脑干部的三叉神经反射系统引起的。全麻药对上呼吸道功能衰竭的影响主要集中在颌骨、口腔功能上。2.全麻药引起的呼吸功能下降对吞咽功能的影响。术后全身麻醉苏醒后常出现呼吸功能减退的现象。吞咽反射和呼吸运动之间有很深的关系。从本研究结果可以看出，呼吸功能的下降与吸入的诱导有关。本研究采用呼吸抑制的方法，从兔的实验模型中抑制生理性呼吸肌的运动。呼吸道压力降低，咽部至食道的压力梯度降低。较少

The frequency of upper respiratory tract stenosis and blockade in the postoperative is very high for the fact of the operation mainly on the jaw oral cavity in which it comes-out. In addition, the action of muscle relaxant and anesthetic remains right after the arousal from the general anesthetic agent, and it becomes liable a case in which there is the respiratory depression for the low recall condition. In spite of being clinically very important, the investigation of the cause of generation and occurrence mechanism is found preoperation CT side cephalo photograph comparison analysis fragmental. In addition, at present unclear point is also abounding. This study adjusted roentgen television and functional-morphological analysis method by the ultrasound imaging equipment and electromyogram of the respiration relation muscle and ventilation physiological testing method, it comprehensively analyzed and diagnosed the disease state of obstructive respiration disorder including the upper r … More espiratory tract failure in the postoperative which dynamically changed. In addition, it has been made that the cause and occurrence mechanism are clarified to be a purpose. The following was clarified in this study period.1.On the effect on reflex systems in which the general anesthetic agent of low concentration uses trigeminal nerve as medium.Ketamine, midazolam, effect on Exteroceptive Suppression(ES1 and ES2) which is one of the reflex system jaw opening reflex in which the proportional control system fall uses trigeminal nerve as medium of general anesthetic agent(low concentration) were examined. Ketamine, midazolam did not recognize the effect of the trigeminal nerve on reflex systems. In the meantime, it was proven that the proportional control system fall affected reflex systems at the epistasis center level, though the effect is not caused trigeminal nerve reflex systems in the brain stem division. The general anesthetic agent is upper respiratory tract failure mainly on jaw oral cavity function on this study result.2.The effect of the decreased respiratory function by general anesthetic agent on the swallow function. There is often a decreased respiratory function fight after the general anesthesia arousal in the postoperative. The relation between deglutition reflex and respiratory movement is deep. It was indicated that the decreased respiratory function was connected with the induction of the aspiration from this study result. In this study the movement of physiological respiratory muscle was suppressed from experimental model using the rabbit by respiratory depression. It was proven the lowering of airway pressure and pressure gradient from the pharynx to the gullet decreased. Less
