NCPAP与面罩吸氧在婴幼儿心脏术后的应用比较

A comparative study of oxygen supply by NCPAP and mask to infant patients with congenital heart disease after operation

目的:研究婴幼儿心脏术后拔除气管插管后的有效供氧方式。方法:将40例拔除气管插管后出现呼吸困难及低氧血症的3岁以下患儿随机分为观察组和对照组,前者22例给予鼻塞正压吸氧(NCPAP),后者18例给予面罩吸氧。对比分析1小时后两组的动脉血PO2和PCO2、再插管例数、入住CICU时间、SpO2、心率、呼吸、血压的变化。结果:观察组患儿的动脉血PO2升高、PCO2下降、再插管例数少(P﹤0.05),有差异;入住CICU时间及心率、呼吸明显下降,SpO2明显升高(P﹤0.01),有显著差异。结论:NCPAP能有效地缓解和治疗婴幼儿心脏术后拔除气管插管后出现的呼吸困难及低氧血症,减少再插管几率和入住CICU的时间。

Objective To study the effective ways of oxygen supply to infant patients with congenital heart disease after operation. Methods 40 patients under 3 years old with respiratory distress and hapoxemia after pulling out the tracheal intubation were divided into two groups. 22 patients of test group were provided oxygen with NCPAP, while 18 patients of control group were treated with the mask To compare the results of blood gas and Sp02, pulse, resp, blood pressure and CICU time after 1 hour. Results Compared with the control group, blood gas indicated P02 was improved, PC02 was declined, again tracheal intubation was reduced （P 〈 0.05）, the CICU monitoring time significantly decreased and heart rate was significantly declined , SpO2 significantly raised（P 〈 0.01 ）. Conclusion It is suggested that NCPAP may play an important role in relieving and treating the respiratory distress and hapoxemia after pulling out the tracheal intubation , it can also reduce the rate of tracheal intubation and decrease the CICU monitoring time.
