巨大儿由于体重的关系,难于自然分娩,容易造成宫内窘迫,胎儿肛门松弛,排出胎粪污染羊水.若吸入污染的羊水,将加重窒息,造成进一步的病理生理改变.本组巨大儿宫内窘迫占27.08%(26/96),羊水混浊占28.13%(27/96),新生儿肺炎发生率为10.42%(10/96),与对照组比较有显著性差异(P<0.01).新生儿肺炎病例均有不同程度的宫内窘迫,羊水混浊,胎膜早破或新生儿窒息史.其中1例伴有缺氧缺血性脑病,另1例伴缺氧缺血性脑病和颅内出血.提示官内窒迫、羊水混浊、新生儿窒息、缺氧缺血性脑病,颅内出血有着密切关系.
Huge children due to the relationship between weight, difficult to spontaneous delivery, likely to cause intrauterine distress, fetal anal relaxation, discharge of meconium-contaminated amniotic fluid .If inhaled contaminated amniotic fluid, will increase the suffocation, resulting in further pathophysiological changes in this group of huge intrauterine The incidence of embolism was 27.08% (26/96), amniotic fluid opacity was 28.13% (27/96), neonatal pneumonia was 10.42% (10/96), which was significantly different from the control group (P <0.01) Child pneumonia cases have varying degrees of intrauterine distress, amniotic fluid opacity, premature rupture of membranes or neonatal asphyxia history.Among which 1 case of hypoxic-ischemic encephalopathy, the other with hypoxic-ischemic encephalopathy and intracranial hemorrhage It is suggested that there is a close relationship between internal stifling, cloudy amniotic fluid, neonatal asphyxia, hypoxic ischemic encephalopathy and intracranial hemorrhage.
