Effects of permissive hypercapnia on inhibiting inflammatory mediators into plasma in respiratory distress syndrome of neonates / 中国医师进修杂志

ABSTRACT

Objective To observe the changes in inflammatory mediators in plasma in respiratory distress syndrome(RDS) of neonates received lung protective ventilation treatment. Methods Sixty newborn infants,diagnosed as RDS of neonatal and needed ventilator support, were recruited from the intensive care unit from May 2003 to May 2006. Infant with RDS were randomly divided into two groups. Both had 30 newborn infants. The infants in the experimental groups received lung protective ventilation treatment tidal volume5-8 ml/kg,positive end-expiratory pressure (PEEP)0.51~0.98 kPa, and the control groups received large tidal volume ventilation (tidal volume10-15 ml/kg,PEEP0-0.29 kPa). The contents of TNF-?, interleukin-6 in plasma were measured. Results After those two therapies, the contents of tumor necrosis factor-?(TNF-?), interleukin-6 in plasma decreased obviously, especially after receiving lung protective ventilation treatment. Conclusions There are statistical differences in the amount of inflammatory mediators released between the experimental group under lung protective ventilation treatment and the control group received large tidal volume ventilation,and better effects are seen in RDS infants under lung protective ventilation treatment .
