18例呼吸衰竭病人PaO_2均<5.33kPa(3.37～5.21kPa),其原发病包括:慢性阻塞性肺水肿,肺心病,重症肺炎等。年龄38～66岁,临床已行气管切开,人工机械通气,并经抗感染,气管内吸痰等综合治疗,未见好转。在经皮血氧饱和度仪持续监测下行支气管肺泡灌洗治疗,通过维持术中SaO_2在70％以上,成功地对18例重度呼吸衰竭的病人进行了32次BAL治疗,成功率100％,且PaO_2、SaO_2改善明显(P<0.05),从而为BAL治疗提供安全可靠的血氧监护手段。
18 patients with respiratory failure PaO_2 <5.33kPa (3.37 ~ 5.21kPa), the primary disease include: chronic obstructive pulmonary edema, pulmonary heart disease, severe pneumonia and so on. Age 38 to 66 years old, clinical tracheotomy, artificial ventilation, and anti-infective, endotracheal suctioning and other comprehensive treatment, no improvement. Continuous monitoring of descending bronchoalveolar lavage with percutaneous oxygen saturation was performed successfully in 32 BAL patients with maintenance of over 70% of SaO_2 during surgery, with a success rate of 100% PaO_2 and SaO_2 were significantly improved (P <0.05), which provided safe and reliable blood oxygen monitoring for BAL.
