Objective To investigate the effect of pulmonary surfactant on neonatal with acute respiratory distress syndrome.Methods98 cases with neonatal respiratory distress syndrome inthe fourth hospital of Ningbo were randomly divided into experimental group and control group, 49 cases in each group.All patients were given warm, anti infection, and maintain the internal environment stability, prevention of bleeding and other conventional treatment.The control group were treated with mechanical CPAP, the experimental group were given pulmonary surfactant 70mg/kg, concentration is 35mg/mL.Pulmonary surfactant was injected slowly by tracheal intubation at supine, lateral(left, right) and semi recumbent position.The drug was distributed evenly in the lung of the patients who were given the drug 1-2 times.Respiratory frequency (RR), pH, oxygen partial pressure (PaO2), partial pressure of carbon dioxide (PaCO2) levels and the incidence of complications, clinical effective rate of the tthe two groups were observed and compared.ResultsCompared with pre-treatment, RR and PaCO2 levels were decreased, pH and PaO2 levels were increased after treatment in the two groups, the differences were statistically significant (P<0.05);compared with the control group, RR, PaCO2 level were lower, pH and PaO2 levels were higher in the experimental group, the differences has statistical significance (P<0.05);compared with the control group, the experimental groupwith a low incidence of complications, clinical effective rate is higher, the difference was statistically significant (P<0.05).ConclusionPulmonary surfactant can reduce the respiratory frequency in neonatal with acute respiratory distress syndrome, improve arterial blood gas levels, which get better clinical curative effect.
