新生儿重度窒息176例,其中伴有羊水(或胎粪)吸入124例,发生率为70.4%。诊断羊水吸入的症状包括呼吸节律不齐、肺部啰音、明显发绀,吮乳差及呕吐等。胎心率异常时羊水吸入发生率明显增加。重度窒息儿的羊水吸入发生率与胎龄。体重关系不明显,但体重≥2000g,胎龄≥37周不伴羊水吸入的病死率为0～2.5%,而伴有羊水吸入的病死率高达20.5%～21%。提出加强产前监护及时处理胎儿宫内窘迫的重要性,并讨论了出生后彻底清理呼吸道的方法。 Severe neonatal asphyxia 176 cases, of which amniotic fluid (or meconium) inhalation 124 cases, the incidence was 70.4%. Diagnosis of amniotic fluid inhalation symptoms include irregular breathing, pulmonary rales, cyanosis, sucking milk and vomiting. Fetal heart rate abnormalities amniotic fluid intake significantly increased the incidence. Amniotic fluid intake and gestational age in children with severe asphyxia. Weight relationship is not obvious, but the weight ≥ 2000g, gestational age ≥ 37 weeks without amniotic fluid intake of 0 to 2.5% mortality, while with amniotic fluid inhalation mortality as high as 20.5% to 21%. Proposed to strengthen the prenatal care timely treatment of fetal distress in the importance of and discuss the method of thorough removal of the respiratory tract after birth.
