ABSTRACT
ObjectiveTo study exogenous surfactants disaturated phosphatidyl choline (DSPC) kinetics in full term infants with respiratory distress syndrome(RDS) who were treated with different dose of poractant alfa.MethodsOne hundred and twenty-two full term infants with RDS undergoing mechanical ventilation were divided into group A (80 cases) and group B (42 cases) by simple random method,who received 100 mg/kg or 200 mg/kg poractant alfa mixed with DSPC.Clinical manifestation and respiratory parameters were recorded,and DSPC half-life period and pool size and endogenous DSPC synthesis rate were calculated.ResultsFifty-six infants (70.0%) received a second dose after(25 ± 11) h and 18 infants (22.5%) received a third dose after(41 ± 11 ) h in group A.Twelve infants ( 28.6% ) received a second dose after (33 ± 8) h and 2 infants (4.8%) received a third dose in group B.DSPC half-life period in group B was longer than that in group A[the fast(32 ± 19) h vs.(15 ± 15) h;the second(43 ±32) h vs.(21 ± 13) h],there was significant difference (P< 0.01 or < 0.05).DSPC synthesis rate and pool size before the first and second doses had no difference between the two groups.But the oxygenation index at the first and the second dose in group B was less than that in group A,there were significant differences (P < 0.01 or < 0.05).ConclusionPoractant alfa given to full term infants with RDS at a dose of 200 mg/kg results in a longerDSPC half-life period,fewer retreatments,and better oxygenation index values.
