鼻腔后份出血行后孔栓塞后常发生并发症,甚至死亡,其机制过去多认为是通过鼻肺反射、血中氧分压(PaO_2)降低和二氧化碳分压增高及低氧血症所致,因而补给氧气。以上结论均系采用间断性动脉血气分析 法(ABG)在填栓时和除栓后24小时检查所获结果,只能反映某特定时间的动脉含氧量,迄今尚无对填栓期全程行动态监测,并将血氧含量与并发症的发生相联系的观察。为此,选用连续脉搏血氧测定法(pulse oxymetry)对后孔栓塞患者行前瞻性连续监测,从阐明
Nasal posterior hemorrhage line posterior orifice embolization often occurs after complications, and even death, the mechanism in the past thought to be through the nose and lung reflex, blood partial pressure of oxygen (PaO_2) and increased carbon dioxide partial pressure and hypoxemia caused, Thus replenishing oxygen. The above conclusions are based on the use of intermittent arterial blood gas analysis (ABG) at the time of filling and 24 hours after removal of the test results obtained can only reflect the oxygen content of a specific period of the artery, so far no full filling period Dynamic monitoring, and blood oxygen content and the incidence of complications linked to the observation. To this end, the use of continuous pulse oximetry (pulse oxymetry) prospective continuous embolization of patients with prospective continuous monitoring, from the elucidation
