１９８３～１９９２十年中，我院活产儿共１２７７２例，胎粪污染羊水（ＭＳＦ）的发生率为１５．４％，前８年变化不大，后两年有所降低，此期间，胎粪吸入综合征（ＭＡＳ）发生率由２．０％降至０．３％，ＭＳＦ的分娩中，ＭＡＳ的发生率由１３．４％降至２．６％，合并症减少，病死率下降，主要是由于加强产程监护，改善复苏技术及治疗措施的结果。但是．有些宫内吸入不易避免，严重病例发生合并症如气胸、持续肺动脉高压等仍导致死亡．针对这些问题，因外已采用了一些新技术，本文分析了几种高危因素，有相当多的ＭＡＳ的新生儿并未发现特殊原因，产前不易估计。
During the ten years from 1983 to 1992, there were 12,772 live births in our hospital. The incidence of meconium-stained amniotic fluid (MSF) was 15.4%. There was little change in the first eight years and a decrease in the latter two years. During this period, The incidence of MAS decreased from 2.0% to 0.3%. During MSF delivery, the incidence of MAS decreased from 13.4% to 2.6% with a decrease in comorbidity and decreased mortality, mainly This is due to the strengthening of labor care and the improvement of recovery techniques and treatment measures. but. Some intrauterine inhalation is not easy to avoid, severe cases of complications such as pneumothorax, pulmonary hypertension continued to cause death. In response to these problems, some new technologies have been adopted. In this paper, several risk factors are analyzed. There are no special reasons for newborns with a considerable number of MAS, which is not easy to estimate before delivery.
