The management of bleeding in early pregnancy. Does admission to hospital for bed rest prevent disease progression or improve fetal outcome in pregnancy complicated by non-proteinuric hypertension? Medical vs. surgical evacuation of first-trimester spontaneous abortion. A randomized controlled trial of complete bed rest versus ambulation in the management of proteinuric hypertension during pregnancy. A randomised trial of surgical, medical and expectant management of first trimester spontaneous miscarriage. Prospective randomised controlled trial of an infection screening programme to reduce the rate of preterm delivery. First trimester threatened miscarriage treatment with human chorionic gonadotrophins: a randomised controlled trial. The effects of hospitalization for bed rest on duration of gestation, fetal growth and neonatal morbidity in triplet pregnancy. A randomized comparison of sublingual and vaginal misoprostol for cervical priming before suction termination of first-trimester pregnancy.
Ultrasound scan findings were analysed for 187 women referred to an emergency gynaecological scanning clinic during a seven month period, with bleeding in early pregnancy. One sixth of the women were not pregnant, one third had non-viable pregnancies and one half had viable pregnancies; 9% of this latter group subsequently miscarried. For the majority of women referred to the clinic, bed rest would have been inappropriate. In this study the value of bed rest and hospitalisation was considered uncertain for women with viable singleton pregnancies of 7-14 weeks gestation and bleeding in the previous 24 hours. Only 23 women with otherwise uncomplicated pregnancies met these criteria and consented to recruitment to a randomized controlled trial: three subsequently miscarried. Emergency scanning as a routine part of the gynaecological service is recommended, thus confining bed rest to those women with viable pregnancies. Reliable evaluation of bed rest and hospitalisation for such women will require a multicentre study. To test whether a policy of admission to hospital for rest is of value in the management of women with non-proteinuric hypertension during pregnancy.
                A randomized controlled trial.
                Harare Maternity Hospital, Zimbabwe.
                218 (28 first pregnancies) women with non-proteinuric hypertension and a singleton pregnancy at between 28 and 38 weeks gestation allocated to rest in hospital or routine outpatient care.
                Admission to hospital for rest. Encouraged to rest in bed although voluntary ambulation around the ward was allowed. The women in the control group were encouraged to continue normal activity at home, to check urine each day for proteinuria. All the women were reviewed weekly.
                Disease progression was assessed by the development of severe hypertension (greater than or equal to 160/110 mmHg), development of proteinuria, need for induction of labour and number of infants born preterm (less than 37 weeks). Fetal outcome was assessed by birthweight, number of infants small-for-gestational age (SGA), and the number of infants requiring admission to the neonatal unit and their length of stay.
                The hospital rest group had a decreased risk of developing severe hypertension (blood pressure greater than or equal to 160/110 mmHg [odds ratio 0.47, 95% CI 0.26-0.83]). No differences were found in fetal growth or neonatal morbidity. The mean antenatal stay in hospital was 22.2 (SD 16.5), and 6.5 (SD 7.9) days in the rest and control groups, respectively.
                Hospital admission for bed rest decreased the risk of developing severe hypertension but no improvement in fetal growth or neonatal morbidity was observed. Fetal monitoring at home and continued outpatient antenatal care provided a safe, alternative policy to hospital admission. To determine whether management of incomplete first-trimester abortion with vaginal misoprostol in an under-resourced setting is a viable treatment option.
                A total of 94 women were randomized to 600 microg of misoprostol intravaginally or to surgical curettage. The women receiving misoprostol were administered a second dose if the abortion was incomplete; and if still not complete after a week, evacuation of retained products of conception was performed. All women had a follow-up visit 2 weeks following complete abortion.
                The overall success rate of medical management was 91.5%, with 15 of 47 successful cases after 1 dose of misoprostol; 8.5% of the 47 women required evacuation of retained products of conception after 1 week because of treatment failure. The success rate in the surgical arm was 100%. Patients in the medical arm had a longer duration of bleeding and a greater need for analgesia. There were no differences in hemoglobin levels, white blood cell count, adverse effects, pain score, and satisfaction with treatment at the follow-up visit. However, more women who received the medical treatment would recommend it or choose it in the future.
                Medical management using 600 microg of misoprostol in 2 doses is effective to treat incomplete first-trimester abortions in an under-resourced setting when there is no evidence of uterine sepsis. Forty patients participated in a randomized controlled trial of complete bed rest versus ambulation as desired in the management of proteinuric hypertension during pregnancy. Daily increases in serum human placental lactogen and oestriol concentrations were greater in the rested group. An especially 'at risk' group of 10 patients with both hyperuricaemia and severe fetal growth retardation was identified. Strict confinement to bed in these cases seemed to encourage the development of the premonitory symptoms of eclampsia, but was associated with a better prognosis for the fetus. Medical management and expectant care have been considered possible alternatives to surgical evacuation of the uterus for first trimester spontaneous miscarriage in recent years.
                To compare the effectiveness and safety of medical and expectant management with surgical management for first trimester incomplete or inevitable miscarriage.
                Forty women were recruited following diagnosis of incomplete or inevitable miscarriage, and randomised to surgical, medical or expectant care via an off-site, computerised enrollment system. The primary outcome was the effectiveness of medical (vaginal misoprostol) and expectant management relative to surgical evacuation, assessed at 10-14 days and 8 weeks post-recruitment. Infection, pain, bleeding, anxiety, depression, physical and emotional recovery were assessed also. Analysis was by intention-to-treat.
                Effectiveness at 8 weeks was lower for medical (80.0%) and expectant (78.6%) than for surgical management (100.0%). Two women in the medical group had confirmed infections. Bleeding lasted longer in the expectant group than in the surgical group. There were no significant differences in pain, physical recovery, anxiety or depression between the groups. 54.6%, 42.9% and 57.1% of the surgical, medical and expectant groups respectively would opt for the same treatment again.
                Expectant care appears to be sufficiently safe and effective to be offered as an option for women. Medical management might carry a higher risk of infection than surgical or expectant care. To evaluate whether a screening strategy in pregnancy lowers the rate of preterm delivery in a general population of pregnant women.
                Multicentre, prospective, randomised controlled trial.
                Non-hospital based antenatal clinics.
                4429 pregnant women presenting for their routine prenatal visits early in the second trimester were screened by Gram stain for asymptomatic vaginal infection. In the intervention group, the women's obstetricians received the test results and women received standard treatment and follow up for any detected infection. In the control group, the results of the vaginal smears were not revealed to the caregivers.
                The primary outcome variable was preterm delivery at less than 37 weeks. Secondary outcome variables were preterm delivery at less than 37 weeks combined with different birth weight categories equal to or below 2500 g and the rate of late miscarriage.
                Outcome data were available for 2058 women in the intervention group and 2097 women in the control group. In the intervention group, the number of preterm births was significantly lower than in the control group (3.0% v 5.3%, 95% confidence interval 1.2 to 3.6; P = 0.0001). Preterm births were also significantly reduced in lower weight categories at less than 37 weeks and <or= 2500 g. Eight late miscarriages occurred in the intervention group and 15 in the control group.
                Integrating a simple infection screening programme into routine antenatal care leads to a significant reduction in preterm births and reduces the rate of late miscarriage in a general population of pregnant women. To determine whether administration of exogenous human chorionic gonadotrophin (hCG) treatment improve the pregnancy outcome in first trimester threatened miscarriages.
                A prospective, double blind, randomised, placebo-controlled trial.
                The Early Pregnancy Assessment Unit, Royal Bolton Hospital, Bolton, United Kingdom.
                One hundred and eighty-three women with vaginal bleeding and a viable fetus seen on ultrasound scan (USS) in the first 12 weeks of pregnancy.
                The patients were randomised to receive either hCG or placebo treatment until 14 weeks of gestation.
                The primary objective of the trial was to determine the miscarriage rate in the hCG arm compared from the placebo arm.
                Of the 183 cases, 87 were randomised to treatment with hCG while 96 were randomised to receive a placebo. Forty-seven (25%) did not comply with the study protocol. The mean [SD] gestational age at presentation was 7 [1.33] weeks. The mean [SD] age of women in study was 27 [5] years in the placebo and 28 [5] in the hCG group. The mean body mass index (kg/m(2)) was 25 [5] in the study. The number of patients actively bleeding per vaginum at presentation was 85 (93%) in placebo group and 79 (96%) in the hCG group. The median number of hCG or placebo injections for both groups was 7. Ten women (11%) in the placebo group proceeded to have a complete miscarriage, as did 10 women (12%) in the hCG group, relative risk (RR) [95% confidence interval (CI)] of 1.1 (0.63-1.6).
                Our study showed no evidence of a difference in the outcome of threatened miscarriages when treated with hCG in the first trimester, this may be because our study sample size was small and follow up was suboptimal. A large, randomised, multicentre trial is still needed to establish the usefulness of hCG treatment in cases of threatened miscarriage. Nineteen women attending a special multiple pregnancy antenatal clinic with a triplet pregnancy were randomly allocated to either bed rest in hospital from 24 weeks gestation onwards until delivery, or to continue conventional outpatient management. Conclusions are limited by the trial size, but the study suggests that routine hospitalization for bed rest decreases the incidence of preterm delivery and light-for-gestational age infants and reduces the need for intensive neonatal care. Although still compatible with change variation, the observations, if confirmed in a larger randomized study, would have considerable implications for clinical practice. The policy needs further evaluation in a large multicentered collaborative study. This randomized trial compares the efficacy and side effects of sublingual and vaginal misoprostol for cervical priming before first-trimester pregnancy termination. One-hundred pregnant women between 6 and 12 weeks of gestation opting for termination of pregnancy by suction evacuation were included in this study. The women were randomly allocated into two groups. Group 1 received 400 microg of sublingual misoprostol and group 2 received 400 microg of vaginal misoprostol 2 h prior to suction evacuation. The abortion was carried out by suction evacuation using a Karman's cannula attached to an electrically operated suction machine under intravenous analgesia. Baseline cervical dilatation, duration of the procedure, operative blood loss, side effects and complications were noted in both groups. There was a significant difference between the sublingual and vaginal misoprostol groups with respect to mean cervical dilatation (8.6 mm vs. 6.8 mm, p < 0.05). However, the duration of the procedure (3.03 min vs. 3.16 min) and the amount of blood loss (29 mL vs. 31.2 mL) were not significantly different between the two groups. The women in the sublingual group experienced significantly more shivering and preoperative vaginal bleeding (68% vs. 56%, p < 0.05). None of the women in the two groups had either uterine perforation or excessive hemorrhage. In our study, sublingual misoprostol (400 microg) was significantly more effective in facilitating cervical dilation prior to surgical abortion than vaginal misoprostol.
There is insufficient evidence of high quality that supports a policy of bed rest in order to prevent miscarriage in women with confirmed fetal viability and vaginal bleeding in first half of pregnancy.
