持续呼气末二氧化碳分压监测在婴幼儿重症肺炎中的应用

APPLICATION OF END-TIDAL CARBON DIOXIDE PARTIAL PRESSURE MONITORING IN INFANTS WITH SEVERE PNEUMONIA

目的探讨行机械通气的婴幼儿重症肺炎的患儿,监测呼气末二氧化碳分压(PetCO2)与动脉血二氧化碳分压(PaCO2)的相关性。方法采取回顾性、自身对照研究方法。选择32例进行机械通气的婴幼儿重症肺炎患儿,在机械通气后同时检测呼气末二氧化碳分压(PetCO2)和动脉血二氧化碳分压(PaCO2)。分别选择机械通气后30min、1h、6h、12h、24h,5个时间点进行检测。结果呼气末二氧化碳分压(PetCO2)和动脉血二氧化碳分压(PaCO2)具有正向关关系(r=0.8210,P<0.0001)。结论进行机械通气的婴幼儿重症肺炎,呼气末二氧化碳分压(PetCO2)和动脉血二氧化碳分压(PaCO2)具有很好的相关性,呼气末二氧化碳分压(PetCO2)可用于判断动脉血二氧化碳分压(PaCO2)变化,可以作为调整呼吸机参数的依据,减少动脉采血痛苦,值得临床推广。

Objective To investigate mechanical ventilation in infants with severe and discuss the correlation between partial pressure of carbon dioxide in end expiration （PETCO2） and in artery （PaCO2 ）. Methods Select thirtytwo infants who with severe pneumonia for mechanical ventilation. After mechanical ventilation, took the function tests about PETCO2 and PaCO2. Selected 5 time points tested . （After 30rain, lh, 6h, 12h, 24h）. Results Arterial carbon dioxide partial pressure （PaCO2） and end- tidal carbon dioxide partial pressure （ Pet CO2 ） showed a positive relationship （ r = 0. 8210,P〈0. 0001）. Conclusions The test shows mechanical ventilation in infants PaCO2 and PETCOM2 has a good correlation. Endtidal carbon di- oxide partial pressure （ Pet CO2 ） can be used to determine arterial carbon dioxide partial pressure （ PaCO2 ） changes, and it can be used as a basis for adjusting ventilator parameters. It can reduce the pain of blood, worthy of promotion.
