Respiratory mechanics dynamic monitoring in neonates with severe respiratory distress syndrome and its clinical significance
Abstract：Objective To study the character of respiratory mechanics insevere respiratory distress syndrome and its clinical significance. Methods We measured the indices of respiratory mechanics,chest radiographsand blood gas in 17 newborns with respiratory distress syndrome(RDS). Results The indices of respiratory mechanics in 17 newborns with RDS showed:Crs were correlated with severity and outcome of the illness. Crs lower than 0.3ml/cmH2O· kg indicated severe illness. Crs lower than 0.2ml/cmH2O· kg was associated with high mortality rate. Crs were negatively correlated with oxygenated index(OI) ( r = - 0.948) and a linear regressive relation was found ( OI = 64.73 - 82.70Crs). Chest X -ray manifestations were negatively correlated with Crs (r = -0.768). 90.9% of the patients were successfully weaned from the ventilator when mean value of Crs was (0.683 + 0. 110)m/(crnH2O·kg). Conclusion Crs monitoring is of clinical significance in evaluating the severity of RDS, directing mechanical ventilation management, reducing frequency of blood gas analysis and radiographs and predicting outcome.
