作者随诊了在新生儿期被救活的呼吸艰难综合征患儿53例,这些患儿,当时均经明确诊断,并在新生儿期从脐动脉导管采血,连续测定动脉血氧分压、二氧化碳分压和氢离子浓度的生化改变,进行观察比较,并按情况需要给以不同浓度的氧吸入处理。当动 The authors followed 53 children with dyspnoea who were rescued during the neonatal period. All of these children were diagnosed at the time and were taken from umbilical artery catheters in the neonatal period for continuous determination of arterial oxygen tension, Carbon dioxide partial pressure and hydrogen ion concentration biochemical changes were observed and compared, and according to the need to give different concentrations of oxygen inhalation treatment.
