Patients and MethodsThe subjects in this stucy were 14 healthy acults with normal respiratory function (control group) and 29 patients (patient group) subjected to sagittal osteotomy accompanied by intermaxillary fixation uncer general anesthesia. Measurement items were the presence of nasal breathing and oral breathing, tical volume (VT) in each respiratory route, respiratory minute volume, respiratory rate (RR), enc -tical C02 concentration (EtCO2), and oxygen saturation (SpO2). In the control group, measurements were taken before and after intermaxillary fixation of upper and lower tooth rows by wire ligation. In the patient group, measurements were taken on the cay before surgery, and when the respiratory condition was stabilizedfollowing extubation aftergeneral anesthesia.ResultsThere were no significant cifferences in any of the measurement items before and after intermaxillary fixation both in the control N - N group whose respiratory route before and after intermaxillary fixati … More on was only nasal breathing, and in the control NO- N group whose respiratory routes were nasal and oral breathing before intermaxillary fixation but only nasal breathing after intermaxillary fixation. In the patient group, there were no significant cifferences in any of the measurement items before and after surgery in the patient N-N group whose respiratory route before surgery and aftergeneral anesthesia during intermaxillary fixation was only nasal breathing.In patient NO-N group who showed nasal and oral breathing preoperatively but showed only nasal breathing postoperatively, the tical volume and respiratory minute volume of the nasal breathing (id not change postoperatively. However, since the respiratory volume of the oral breathing cisappearec, the total respiratory volume cecreased significantly postoperatively. The respiratory rate and SpO2 cid not change. EtCO2, however, increasec. In the patient group, we comparatively stucied only N - N and NO-N.There were only a few cases in which the preoperative and postoperative respiratory routes were NO-O (3 case), N- 0(1 case), 0 -N (1 case), and NO-NO (one case).

患者与方法选择呼吸功能正常的健康成人14例（对照组）和全麻下行矢状截骨颌间固定术的患者29例（患者组）。测定项目为鼻呼吸和口呼吸的存在、每种呼吸途径的呼吸量（VT）、每分钟呼吸量、呼吸频率（RR）、吸入CO2浓度（EtCO 2）和血氧饱和度（SpO 2）。在对照组中，测量前和后颌间固定的上下牙列线结扎。患者组在手术前和全身麻醉拔管后呼吸状况稳定时进行测量。结果对照组N-N组（颌间固定前后呼吸路径均无明显差异）颌间固定前后的任何测量项目均无明显差异。 ...更多信息 NO-N组颌间固定前呼吸途径为经鼻和经口呼吸，颌间固定后呼吸途径为经鼻呼吸。在患者组中，术前和全麻后颌间固定术呼吸途径仅为鼻呼吸的患者N-N组，术前鼻呼吸和口呼吸，术后仅为鼻呼吸的患者NO-N组，术前、术后各测量项目均无显著性差异。术后鼻呼吸的实际通气量和每分钟通气量无明显变化。但由于口呼吸的呼吸量减少，术后总呼吸量明显减少。呼吸频率和SpO 2无变化。而EtCO 2则增加。患者组仅对N-N和NO-N两种呼吸方式进行了对比研究，仅少数患者术前术后呼吸方式为NO-O（3例）、N- 0（1例）、0 -N（1例）、NO-NO（1例）。少
