RESUMEN
Objective To investigate the clinical,safety and cost effect of porcine pulmonary surfactant (import)and bovine pulmonary surfactant(domestic)with full dose and low dosage of early treatment for late preterm children with respiratory distress syndrome,for the clinical selection treatment programs provide a reference.Methods Late preterm children with respiratory distress syndrome were divided into full dose group A of 24 cases,low dose group A of 25 cases,full dose group B of 26 cases,low dose group B of 24 cases.The first dose of full dose group A was 200mg/kg,the first dose of low dosage group A was 100mg/kg,again administered doses was 100mg/kg,the first dose of full dose group B was 70mg/kg,the first dose of low dosage group B was 50mg/kg,again administered dose was 50mg/kg.Results The differences of PaO2 ,PaCO2 ,FiO2 ,OI between two low dosage groups and full dose group A were significantly different.Treated 6h,the differences of PaCO2 ,FiO2 between low dosage group B and full dose group A were significantly different(q =3.273,3.236,all P <0.05).A group of low volume with a sufficient amount PaO2 6 h B group differences were statistically significant(q =3.823,P <0.05),12h of PaO2 ,PaCO2 ,FiO2 ,OI with enough B group difference was statistically significant(q =3.293,3.923,3.423,3.434,all P <0.05),24h of FiO2 , OI group was significantly lower than the full amount of B(q =3.234,3.356,all P <0.05).Low dose group B 6h, 12h,24h of PaO2 was significantly lower than enough group B,6h,12h of PaCO2 were significantly higher than enough group B(q =3.892,3.922,3.583,all P <0.05),12h,24h of FiO2 ,OI group were significantly higher than a suffi cient amount B(12h of q =3.892,3.762,24h of q =3.819,3.678,P <0.05),24h of OI was significantly higher than the low amount of a group(q =3.784,P <0.05).Chest evaluation 12h,24h grade difference between groups was sta-tistically significant(Z =3.982,5.323,all P <0.05).Two low -volume set of ventilator -associated pneumonia rates were 16.00%,16.67%,significantly higher than the amount of the two -legged group(low dose group A χ2 =4.988, 5.023,low dose group B χ2 =5.102,5.234,all P <0.05).Conclusion Porcine pulmonary surfactant(import)and bovine pulmonary surfactant(domestic)full dose early treatment of late preterm children with respiratory distress syn-drome could significantly relieve pulmonary symptoms and signs,effects are better than low dosage,and has high secu-rity,low dosage treatment does not reduce the cost of treatment,bovine pulmonary surfactant therapy administered in an amount sufficient lower cost,select the appropriate treatment plan based on your specific needs.
