Study of cause and treatment efficiency of acute respiratory distress syndrome in full-term newborns / 中国综合临床

ABSTRACT

Objective To explore the pathogenesis of acute respiratory distress syndrome (ARDS) in fullterm newborns, and to assess the effect of pulmonary surfactant. Methods All full-term newboms were divided into two groups,with 50 cases in group A and 12 cases in group B. Compared to the treatment of group A,pulmonary surfactant was added to group B. The indicators of pH, PaO2, PaCO2, SaO2, HCO3- were compared between the two groups.Results The cure rate was 92% in group B , which was significant higher than that of 80% in group A( t = 3. 5,P < 0. 05 ). There were 42 cases of neonatal asphyxia (68%), 36 cases of asphyxia combined aspiration pneumonia (58% ) ,19 cases of cesarean section(31% ) ,6 cases of milk aspiration pneumonia (10% ) and 3 cases of infectious pneumonia (5 % ). The AUC was 0. 80,0. 76,0. 35,0. 83 and 0.74, respectively.Neonatal asphyxia, asphyxia combined aspiration pneumonia,milk aspiration pneumonia and infectious pneumonia were associated with ARDS in full-term newborns. PaO2 in group A and B was (78. 80 ± 8. 2 ) mm Hg and (87. 20 ± 8. 30) mm Hg, respectively (t = 4. 56, P < 0. 05 ). SaO2 in group A was (89. 50 ± 5.40) % ,which was significantly lower than that of (99. 63 ± 3. 30 ) % in group B (t = 5. 78, P < 0. 05). Conclusions There are various causes of ARDS in full-term newborns.Intensive clinical observation and continuous monitoring of blood oxygen saturation will be helpful to improve the efficiency of treatment Pulmonary surfactants can improve the efficiency in the treatment of ARDS in the full-term newboms.
