There are no notes to display. Add a note. In addition to these evidence-based recommendations, the guideline development group also identifies points of best clinical practice in the original guideline document. D - All women with recurrent first-trimester miscarriage and all women with one or more second-trimester miscarriage should be screened before pregnancy for antiphospholipid antibodies.
D - Cytogenetic analysis should be performed on products of conception of the third and subsequent consecutive miscarriage s. D - Parental peripheral blood karyotyping of both partners should be performed in couples with recurrent miscarriage where testing of products of conception reports an unbalanced structural chromosomal abnormality. D - Women with second-trimester miscarriage should be screened for inherited thrombophilias including factor V Leiden, factor II prothrombin gene mutation and protein S.
B - Pregnant women with antiphospholipid syndrome should be considered for treatment with low-dose aspirin plus heparin to prevent further miscarriage. Pregnancies associated with antiphospholipid antibodies treated with aspirin and heparin remain at high risk of complications during all three trimesters. Although aspirin plus heparin treatment substantially improves the live birth rate of women with recurrent miscarriage associated with antiphospholipid antibodies, these pregnancies remain at high risk of complications during all three trimesters, including repeated miscarriage, pre-eclampsia, fetal growth restriction and preterm birth; this necessitates careful antenatal surveillance.
A - Neither corticosteroids nor intravenous immunoglobulin therapy improve the live birth rate of women with recurrent miscarriage associated with antiphospholipid antibodies compared with other treatment modalities; their use may provoke significant maternal and fetal morbidity. D - The finding of an abnormal parental karyotype should prompt referral to a clinical geneticist.
Genetic counselling offers the couple a prognosis for the risk of future pregnancies with an unbalanced chromosome complement and the opportunity for familial chromosome studies. Reproductive options in couples with chromosomal rearrangements include proceeding to a further natural pregnancy with or without a prenatal diagnosis test, gamete donation and adoption. C - Preimplantation genetic screening with in vitro fertilisation treatment in women with unexplained recurrent miscarriage does not improve live birth rates.
C - There is insufficient evidence to assess the effect of uterine septum resection in women with recurrent miscarriage and uterine septum to prevent further miscarriage. A - Cervical cerclage is associated with potential hazards related to the surgery and the risk of stimulating uterine contractions and hence should be considered only in women who are likely to benefit.
B - Women with a history of second-trimester miscarriage and suspected cervical weakness who have not undergone a history-indicated cerclage may be offered serial cervical sonographic surveillance. B - In women with a singleton pregnancy and a history of one second-trimester miscarriage attributable to cervical factors, an ultrasound-indicated cerclage should be offered if a cervical length of 25 mm or less is detected by transvaginal scan before 24 weeks of gestation.
B - There is insufficient evidence to evaluate the effect of progesterone supplementation in pregnancy to prevent a miscarriage in women with recurrent miscarriage. B - There is insufficient evidence to evaluate the effect of human chorionic gonadotrophin supplementation in pregnancy to prevent a miscarriage in women with recurrent miscarriage.
A - Suppression of high luteinising hormone levels among ovulatory women with recurrent miscarriage and polycystic ovaries does not improve the live birth rate.
C - There is insufficient evidence to evaluate the effect of metformin supplementation in pregnancy to prevent a miscarriage in women with recurrent miscarriage.
A - Paternal cell immunisation, third-party donor leucocytes, trophoblast membranes and intravenous immunoglobulin in women with previous unexplained recurrent miscarriage does not improve the live birth rate.
Immune treatments should not be offered routinely to women with recurrent miscarriage outside formal research studies. C - There is insufficient evidence to evaluate the effect of heparin in pregnancy to prevent a miscarriage in women with recurrent first-trimester miscarriage associated with inherited thrombophilia. A - Heparin therapy during pregnancy may improve the live birth rate of women with second-trimester miscarriage associated with inherited thrombophilias.
Women with known heritable thrombophilia are at an increased risk of venous thromboembolism. B - Women with unexplained recurrent miscarriage have an excellent prognosis for future pregnancy outcome without pharmacological intervention if offered supportive care alone in the setting of a dedicated early pregnancy assessment unit.
Data suggest that the use of empirical treatment in women with unexplained recurrent miscarriage is unnecessary and should be resisted. Furthermore, clinical evaluation of future treatments for recurrent miscarriage should be performed only in the context of randomised trials of sufficient power to determine efficacy. Good Practice Point - Recommended best practice based on the clinical experience of the guideline development group. The type of supporting evidence is identified and graded for most recommendations see the "Major Recommendations" field.
Appropriate evaluation and management of couples with recurrent early pregnancy loss to increase the chance for a successful live birth. They present recognised methods and techniques of clinical practice, based on published evidence, for consideration by obstetricians and gynaecologists and other relevant health professionals. The ultimate judgement regarding a particular clinical procedure or treatment plan must be made by the doctor or other attendant in the light of clinical data presented by the patient and the diagnostic and treatment options available.
This means that RCOG guidelines are unlike protocols or guidelines issued by employers, as they are not intended to be prescriptive directions defining a single course of management.
Departure from the local prescriptive protocols or guidelines should be fully documented in the patient's case notes at the time the relevant decision is taken. The Cochrane Library and Cochrane Register of Controlled Trials were searched for relevant randomised controlled trials, systematic reviews, and meta-analyses.
A search of Medline from to was also carried out. The date of the last search was November In addition, relevant conference proceedings and abstracts were searched. This was combined with a keyword search using 'human', 'female', 'pregnancy', 'abortion', 'miscarriage', 'habitual', 'recurrent', 'randomised controlled trials' and 'meta-analysis'.
Once the evidence has been collated for each clinical question it needs to be appraised and reviewed refer to section 3 in "Development of RCOG Green-top guidelines: producing a clinical practice guideline" for information on the formulation of the clinical questions; see the "Availability of Companion Documents" field. For each question, the study type with least chance of bias should be used. If available, randomised controlled trials RCTs of suitable size and quality should be used in preference to observational data.
This may vary depending on the outcome being examined. The level of evidence and the grade of the recommendations used in this guideline originate from the guidance by the Scottish Intercollegiate Guidelines Network SIGN Grading Review Group, which incorporates formal assessment of the methodological quality, quantity, consistency, and applicability of the evidence base.
An objective appraisal of study quality is essential, but paired reviewing by guideline leads may be impractical because of resource constraints. Once evidence has been collated and appraised, it can be graded. A judgement on the quality of the evidence will be necessary using the grading system see the "Rating Scheme for the Strength of the Evidence" field. Where evidence is felt to warrant 'down-grading', for whatever reason, the rationale must be stated.
Evidence judged to be of poor quality can be excluded. Any study with a high chance of bias either 1— or 2— will be excluded from the guideline and recommendations will not be based on this evidence. This prevents recommendations being based on poor-quality RCTs when higher-quality observational evidence is available. The development of guidelines involves more than the collation and reviewing of evidence. Even with high-quality data from systematic reviews of randomised controlled trials, a value judgement is needed when comparing one therapy with another.
This will therefore introduce the need for consensus. Equally, in contrast to other guideline groups, the topics chosen for development as Green-top guidelines are concise enough to allow development by a smaller group of individuals. In agreeing the precise wording of evidence-based guideline recommendations and in developing consensus-based 'good practice points', the Guidelines Committee GC will employ an informal consensus approach through group discussion.
In line with current methodologies, the entire development process will follow strict guidance and be both transparent and robust. The RCOG acknowledges that formal consensus methods have been described, but these require further evaluation in the context of clinical guideline development. It is envisaged that this will not detract from the rigor of the process but prevent undue delays in development.
Following discussion in the Guidelines Committee GC , each Green-top guideline is formally peer reviewed. At the same time, the draft guideline is published on the Royal College of Obstetricians and Gynaecologists RCOG Web site for further peer discussion before final publication.
All comments will be collated by the RCOG and tabulated for consideration by the guideline leads. Each comment will require discussion. Where comments are rejected then justification will need to be made. Following this review, the document will be updated and the GC will then review the revised draft and the table of comments. Once the GC signs-off on the guideline, it is submitted to the Standards Board for approval before final publication.

Antenatal Screening For example, for a week-5 embryo, the EDD would be days from the embryo age date. Likewise, the EDD for a day-3 embryo would be days from the embryo replacement date. Using a single accuracy examination in the second trimester off assist in determining the gestational age enables simultaneous fetal anatomic evaluation. With rare exception, if a first-scan ultrasound examination was performed, especially one consistent with LMP dating, gestational age should not be adjusted based on a second-week ultrasound examination.

Advice from the UK government is rapidly changing as more is learned about the virus. We are updating this information as new guidance becomes available. We understand that many of you will be very worried and have lots of questions. We will do our best to support you through these difficult times. As like everyone else, all pregnant women are currently advised to avoid unnecessary contact with people and going out of the house, except in special circumstances. This is being called social distancing. If you are in your third trimester more than 28 weeks pregnant you should be particularly attentive to social distancing and minimising your contact with others. Self-isolating involves staying at home and only going outside for exercise, avoiding contact with others.

In times of COVID with the current situation changing rapidly, reconfiguration of antenatal and postnatal services is vital. Pregnant women will continue to need as much support, advice, care and guidance in relation to pregnancy, childbirth and early parenthood as before the COVID pandemic. But on top of that, much more patient education and mental support is needed. It is essential that care remains available and accessible to ensure continued support for women with their complex needs. Isolation, financial difficulties, insecurity, inability to access support systems are recognized factors putting mental wellbeing at risk. The corona virus epidemic increases the risk of perinatal anxiety, endogene depression, sleep depriviation and malnutrition.

Мы терпим бедствие! - крикнул техник. - Все линии устремились к центру. С левого экрана в камеру неотрывно смотрели Дэвид и агенты Смит и Колиандер. На ВР последняя стенка напоминала тонюсенькую пленку. Вокруг нее было черно от нитей, готовых ринуться внутрь. Справа бесконечной чередой мелькали кадры, запечатлевшие последние минуты Танкадо: выражение отчаяния на его лице, вытянутую руку, кольцо, поблескивающее на солнце. Сьюзан смотрела на эти кадры, то выходившие из фокуса, то вновь обретавшие четкость.
Она вглядывалась в глаза Танкадо - и видела в них раскаяние.

ГЛАВА 54 - Пусти. А потом раздался нечеловеческий крик. Это был протяжный вопль ужаса, издаваемый умирающим зверем. Сьюзан замерла возле вентиляционного люка.
Справа бесконечной чередой мелькали кадры, запечатлевшие последние минуты Танкадо: выражение отчаяния на его лице, вытянутую руку, кольцо, поблескивающее на солнце. Сьюзан смотрела на эти кадры, то выходившие из фокуса, то вновь обретавшие четкость. Она вглядывалась в глаза Танкадо - и видела в них раскаяние.
Это не вирус? - с надеждой в голосе воскликнул Бринкерхофф.
Смит был прав. Между деревьев в левой части кадра что-то сверкнуло, и в то же мгновение Танкадо схватился за грудь и потерял равновесие. Камера, подрагивая, словно наехала на него, и кадр не сразу оказался в фокусе. А Смит тем временем безучастно продолжал свои комментарии: - Как вы видите, у Танкадо случился мгновенный сердечный приступ. Сьюзан стало дурно оттого, что она увидела.
