This study investigated the changes in partial pressure of oxygen during surgical removal of wisdom teeth utilizing a spontaneous ventilation general anesthesia technique with enflurane. Simultaneous transcutaneous and arterial blood gas determination confirmed the presence of two oxygen patterns. Normal preoperative pulmonary function tests, coupled with the stability of the Paco(2) between surgery and extubation, indicates that the 23±10 mmHg increase in transcutaneous oxygen (Ptco(2)) reported in 14 of 27 patients evaluated, was due to ventilation perfusion defects, since 13 of the 27 patients showed a 149±22 mmHg increase in Ptco(2) during the same time period.
本研究调查了在使用安氟醚的自主通气全身麻醉技术拔除智齿手术过程中氧分压的变化。同时进行的经皮和动脉血气测定证实存在两种氧模式。术前肺功能测试正常，再加上手术和拔管之间动脉血二氧化碳分压（Paco₂）的稳定性，表明在评估的27例患者中有14例经皮氧分压（Ptco₂）升高23±10 mmHg是由于通气灌注缺陷所致，因为在同一时期，27例患者中有13例的Ptco₂升高了149±22 mmHg。
