Objective

To investigate influences of tumor necrosis factor-α(TNF-α) , interleukin-8(IL-8) and vascular endothelial growth factor(VEGF) of neonates with meconium aspiration syndrome(MAS) treated by proportional assist ventilation (PAV) .

Methods

From January 2011 to October 2013, a total of 30 neonates with MAS who required mechanical ventilation were recruited into this study.They were divided randomly into two groups according to different ventilation modes PAV group (n=15, supported by PAV mode) and synchronized intermittent mandatory ventilation (SIMV) group (n =15, supported by SIMV mode) .There had no significant differences between two groups on age, gestation age, birth weight, and so on (P>0.05) .At the same time, another 10 healthy term infants were selected as control group.The plasma TNF-α, IL-8 and VEGF levels of neonates in three groups were measured by enzyme linked immunosorbent assay at the first day and third day after birth.The study protocol was approved by the Ethical Review Board of Investigation in Huaian Maternity and Child Healthcare Hospital Affiliated to Yangzhou University Medical Academy.Informed consent was obtained from all participates' parents.

Results

There had no statistically significant differences of TNF-α levels among three groups at first day and third day [(1 395.80 ± 426.46) ng/ L vs.(1 428.27 ± 414.24) ng/ L vs.(374.30 ± 229.91) ng/ L; (1 356.87 ± 315.54) ng/ L vs.(1 602.13 ± 371.10) ng/ L vs.(383.30 ± 187.00) ng/ L; F=27.573, 48.142, P=0.000], there also had statistically significant differences of IL-8 levels among three groups at first day and third day [(2.231 ± 1.063) μg/ L vs.(2.409 ± 1.058) μg/ L vs.(0.398 ± 0.214) μg/ L; (1.813 ± 0.701) μg/L vs.(2.484 ± 1.049) μg/ L vs.(0.409 ± 0.231) μg/ L; F=216.198, 21.173, P= 0.000], and there had no statistically significant differences of VEGF levels among three groups at first day and third day [(167.07 ± 77.23) ng/ L vs.(179.93 ± 78.83) ng/ L vs.(41.90 ± 13.51) ng/ L; (141.73 ± 52.69) ng/ L vs.(186.27 ± 68.25) ng/ L vs.(39.10 ± 10.14) ng/ L; F=14.092, 22.987, P=0.000].

Conclusions

In case to maintain normal oxygen saturation and blood gas, PAV mode can reduce the incidence rate of ventilation-induced lung injury than that of SIMV mode.
