RESUMO
Objective To analyze the clinical effects of low molecular heparin calcium on early onset severe pre-eclampsia.Methods Sixty patients with early onset severe pre-eclampsia at 26-34 weeks of gestational age were divided into treatment group(28 cases)and control group(32 cases).The conventional treatment was delivered in control group and low molecalar heparin calcium(LMWHC)was used in treatment group additionally.The time of prolonged gestational age,umbilical arterial S/D ratio,amniotic fluid index,placenta weight,neonatal weight and Apgar score were measured in two groups.Results The time of prolonged gestational age was 10.19 ±4.57days in treatment group and 6.14 ±3.56 days in control group,which were significantly different(P ＜ 0.01).Umbilical arterial S/D ratio,amniotic fluid index,placenta weight and neonatal weight were all significantly different between the two groups(P ＜ 0.05).Neonatal Apgar score in treatment group was remarkably improved(P ＜ 0.01).Conclusion LMWHC treatment in the patients with early onset severe pre-eclampsia could extend gestational age,increase neonatal weight and improve perinatal outcomes.
RESUMO
Objective To compare the effects of three artificial abortion methods, Mifepriston with Misopro-fil,Rivanol with Mifepristone and Rivanol,in mid-term pregnancy. Methods 235 women who were pregnant for 12 to 28 weeks and volunteered to abort with drugs were selected and observed. The total subjects were randomly divided into three groups,study group Ⅰ (n=80),study group Ⅱ (n=78),and control group (n=77). In study group Ⅰ, each was given Mifepristone 50 mg, po, bid, for 3 days. On the fourth day, Misoprofil 200-1000 μg was administered though vagina. In study group Ⅱ, Rivanol(70-100 mg) was injected into amniotic cavity and at the same tame, Mife-pfistone,75 mg was given bid,po,for each case for 1 day. In study group Ⅲ,each case was injected with Rivanol (70-100 nag) only into amniotic cavity. Results The complete abortion rate in study group Ⅰ, Ⅱ and Ⅲ was 88.75% (71/80), 65.38% (51/78), 38.96% (30/77) respectively. The success rate was 98.75% (79/80), 71.79% (56/78),76.62% (59/77) respectively. The mean time from the initial uterine contraction to the expulsion of the fetus and placenta was (6.85±3.68) h, (8.87±3.58) h, (14.67±3.50) h respectively. The volume of in-trapartum and postpartum vaginal hemorrhage within 2 hours was (80.86±40.28) ml, (94.70±42.35) ml, (120. 68±43.30)ml respectively. The complete abortion rate and success rate in study group Ⅰ was significantly greater than that in study group Ⅱ and study group Ⅲ. In addition, the birth process was shorter and the vaginal hemorrhage was less significantly in study group Ⅰ than those in the other two groups (P<0.01). The complete abortion rate in study group Ⅱ was significantly greater than that in study group Ⅲ (P<0.01). Conclusions Mffepristone admin-istered with Misoprpfil has many advantages usages, such as high complete abortion rate and success rate, short birth process, and less volume of vaginal hemorrhage, when used for artificial abortion in mid-term pregnancy. They are es-pecially suitable for the mid-term artificial abortion under 20-week pregnancy. Rivanol administered with Mifepristone can raise complete abortion rate,shorten labor process and decrease vaginal hemorrhage when they are used in artifi-cial abortion. They are suitable for the mid-term artificial abortion above 16-week pregnancy. The stage of labor lasts long when using only Rivanol for artificial abortion. The pain is relatively heavier and the rate of incomplete abortion is higher.
