Abstract:
The fetal inflammatory response syndrome (FIRS) is a state of activation of the innate immune system in the fetus body and is a kind of neonatal inflammation for 72 hours after birth.It is defined as the following items ＞ 2:(1) breathing too fast (＞ 60 times/min),accompanied by breathing difficulties or with oxygen desaturation; (2) temperature instability ＞ 37.9 ℃ or ＜ 36 ℃ ; (3) capillary filling time ＞ 3 s;(4) the white blood cell count ＞34 × 109/L,or ＜4 × 109/L; (5) CRP ＞ 10 mg/L; (6) IL-6 or IL-8 ＞70 g/ml;(7) gene testing of 16S rRNA for PCR is positive.FIRS can be induced by infectious and non-infectious factors.In FIRS,fetal immune system is over-activated to the external violation,which causes uncontrolled release of inflammatory mediators and cytokines.A variety of inflammatory mediators and cytokines directly or indirectly activate the coagulation system and interfere with the body's anticoagulation system,which induces the coagulation disorders.Multiple organ systems involved in the inflammatory response throughout this process.FIRS can lead to premature delivery,perinatal death,cerebral white matter damage,necrotizing enterocolitis,and affect fetal lung maturity and multi-organ damage.In order to reduce fetal injury,it is necessary for appropriate treatment and prediction of the FIRS.
