高流量氧疗和无创呼吸机辅助对成人心脏外科手术后低氧血症的疗效比较

Comparison of the Effects of High Flow Oxygen Therapy and Noninvasive Ventilator Assistance on Hypoxemia After Cardiac Surgery in Adults

目的:探讨高流量氧疗和无创呼吸机辅助对成人心脏外科手术后低氧血症的疗效差异.方法:收集本院心脏外科手术后的患者,随机分为研究组(采取高流量氧疗技术)和对照组(采取无创呼吸机辅助).对比两组氧和指数的改善程度;两组二次气管插管及耐受性及两组患者监护室住院时间.结果:48h及72h,研究组氧和指数好转率(90%)优于无对照组(50%),两组结果比较有差异(P<0.05);研究组二次气管插管率低于对照组,耐受性高于对照组,两组结果比较有差异(P<0.05);研究组患者监护室住院时间短于对照组,两组结果比较有差异(P<0.05).结论:术后正常脱离有创呼吸机后出现低氧的患者,给予高流量加温湿化给氧,患者舒适度高,能有效改善氧和指数,减少二次气管插管比例,缩短住ICU的住院时间.

Objective:To investigate the effect of high flow oxygen therapy(hfot)and noninvasive ventilator on hypoxemia after cardiac surgery in adults.Methods:Patients after cardiac surgery in our hospital were randomly divided into two groups:Study Group(with high flow oxygen therapy)and control group(with noninvasive ventilator).The improvement degree of oxygen and index,the second intubation and tolerance of the two groups and the hospital stay time of the two groups were compared.Results:At 48h and 72h,the improvement rate of oxygen and index in the study group(90%)was better than that in the non control group(50%),there was a difference between the two groups(P<0.05);the rate of second tracheal intubation in the study group was lower than that in the control group,and the tolerance was higher than that in the control group,there was a difference between the two groups(P<0.05);the length of stay in the intensive care room in the study group was shorter than that in the control group,and there was a difference between the two groups(P<0.05).Conclusion:The patients with hypoxia after normal separation from the invasive ventilator were given high flow of warm and humidified oxygen.The patients’comfort was high,which could effectively improve the oxygen and index,reduce the proportion of secondary tracheal intubation,and shorten the length of stay in ICU.
