Comparative Study Clinical Trial Controlled Clinical Trial[Application of nitrous oxide in labor analgesia].
Labor analgesia with nitrous oxide was studied in 34 parturients, and another 50 women taking no drug as the control group. The analgesic effect was satisfactory. By Mulleetr's pain in labor score, 91.18% women had score of 0-1, and their respiratory and circulatory functions were not affected. ⋯ Uterine contraction, progress of labor and neonatal Apgar score were not interferred, and postpartum bleeding was not increased. There was no complications in the treatment group. This study suggests that nitrous oxide with enough oxygen inhalation is one of the good drug for obstetric analgesia, but its concentration must be strictly controlled.

[Neonatal effects of uterine incision-to-delivery interval during elective cesarean section under epidural anesthesia].
The relationships between uterine incision to delivery interval (U-DI) and neonatal umbilical blood acid-base status and Apgar scores at 1-minute were studied in 130 healthy parturients undergoing elective cesarean section under epidural anesthesia. U-DI was correlated with umbilical venous (UV) and umbilical arterial (UA) pH, PCO2 and PO2, and was also correlated with 1-minute Apgar scores. ⋯ The only two newborns with low 1-minute Apgar scores (6 and 3) in the present study both had prolonged U-DI (> 150 sec) and inhaled amniotic fluid just before the delivery. It is concluded that U-DI of more than 150 sec has considerable influence on the neonatal status.

[Diagnosis and management of obstetric acute disseminated intravascular coagulation].
Twenty-seven in-patients with obstetric DIC in our hospital from Jan. 1971 to Dec. 1990 were analysed retrospectively. The incidence was 0.12% in the first decade and 0.02%, in the second, showing a difference of significance between them. The most common predisposing factors included amniotic fluid embolism, abruptio placenta and hemorrhagic shock. ⋯ It is important that early diagnosis and much attention paid to clinical characteristics together with serial laboratory tests. Key management should include prompt treatment and eradication of predisposing factors. Quick decision spite of to terminate the pregnancy and even hysterectomy should be done in some risks.

[Study of intrauterine cytomegaloviruses infection in pregnant women and fetuses].
Detection of cytomegaloviruses (CMV) DNA in urine samples from pregnant women and newborns' cord blood was done by DNA-DNA hybridization. 33.3% of pregnant women showed CMV DNA sequences in the 1-3 months, 36.4% in the 4-6 months and 38.2% in the 7-9 months. The results suggested that the CMV infection rate of pregnant women increased as time went on.75.0% women with history of abnormal pregnancies showed CMV in their urine and 30.4% newborns' cord blood was positive for CMV. It is apparently that CMV infection rate in women with history of abnormal pregnancies was much higher than that of normal pregnant women and the danger of miscarriage in pregnant women with primary CMV infection at early pregnancy increased. CMV congenital infection rate was also high in newborns.
