The total risk of stillbirth after 26 weeks in MC twins (21.7/ 1000 fetuses) was significantly higher (OR 3.26, 95% CI 2.36–4.5) than in DC twins (6.7/1000 fetuses). The prospective risk of stillbirth in MC twins did not change significantly between 26+ weeks (3.6/ 1000 fetuses) and 36+ weeks (5.2/1000 fetuses, OR 1.85, 95% 0.3–13.2). The equivalent figures for DC twins were 0.8/1000 fetuses and 1.7/1000 fetuses, respectively (OR 3.4, 95% 0.9–13.2).

Objective: Monochorionic (MC) pregnancies are routinely
delivered electively at various late preterm gestations with the
intention of avoiding stillbirth. The aim of this study was to
evaluate the prospective risk of late stillbirth in a large regional
cohort and undertake a systematic review of the literature on
routinely managed twin pregnancies of known chorionicity.
Methods: A retrospective study of all twin births of known
chorionicity from a large regional cohort of nine hospitals
(STORK collaborative) taken over a 10 year period matched to a
mandatory national register of stillbirth (CMACE). The data of
the current study was included in a systematic review of selected
studies of stillbirth in routinely managed twin pregnancies of
known chorionicity.
Results: A total of 3005 twin pregnancies delivered after 26 weeks of
gestation in the STORK collaborative, and this was combined with
data from eight studies selected from the systematic review of the
literature. The total risk of stillbirth after 26 weeks in MC twins (21.7/
1000 fetuses) was significantly higher (OR 3.26, 95% CI 2.36–4.5)
than in DC twins (6.7/1000 fetuses). The prospective risk of stillbirth
in MC twins did not change significantly between 26+ weeks (3.6/
1000 fetuses) and 36+ weeks (5.2/1000 fetuses, OR 1.85, 95%
0.3–13.2). The equivalent figures for DC twins were 0.8/1000 fetuses
and 1.7/1000 fetuses, respectively (OR 3.4, 95% 0.9–13.2).
Conclusion: The risk of stillbirth in MC twins does not appear to
increase significantly near term. This observation may be due to a
policy of routine surveillance and elective delivery from 36 weeks.
The data does not support a policy of elective birth before
36 weeks of gestation in MC pregnancies.

Dignity in maternity care: literature review andaudit of complaints

United Kingdom
In the UK the concept of dignity and respect in health care
commands much public and media interest, predominantly in
elderly care. However, there is a paucity of work regarding dignity
and respect in obstetrics and gynaecology despite its important
and topical nature. In order to begin exploring how the concept
might be studied in our specialty we undertook a literature review
on dignity and respect in obstetrics and gynaecology from 2001 to
2011 and identified key themes. Formal complaints to the
department over a 2 year period were then mapped to the themes
identified in the literature review.
The following threats to dignity were identified: discrimination
against women, fear, pain, intimate examinations, power of care-
giver over the woman, over-medicalisation, excessive form-filling
and staff shift changes. Dignity was maintained by the woman
herself through control of the private sphere, setting appropriate
boundaries and retaining ownership of pregnancy, childbirth and
post-natal care. It was also maintained by healthcare teams that
treated women as individuals, ensured the patient was not
exposed either physically or emotionally, and allowed women
their desired level of control. Maintenance of dignity required
women to have a relationship based on trust in the knowledge
and skills of their health care provider and was strongly associated
with honouring requests for pain relief.
The analysis of departmental complaints revealed clustering
around domains addressing pain management, communication
and attitude, not around areas such as autonomy, personal
hygiene, privacy or safety. When compared with the literature
review we had fewer complaints than expected regarding
autonomy, but the complaints revealed no additional themes that
had not been identified in the literature.
Combining the results of the complaint analysis exercise and the
literature review enabled us to plan future service user based
feedback, allowing active quality assurance based on sound
evidence rather than solely relying on a complaint driven system
to effect change. Finally we regard this as a chance to highlight
areas within our specialty that we can reflect on to bring the best

Informed Consent – What is the evidence?
Robertson, C1; Verco, C2

Background: Informed consent, a fundamental ethical and legal
aspect of medical care, is part of a continuum which is the clinical
encounter. The documentation of ‘informed consent’ may not
always accurately reflect what has been discussed due to time
constraints and other variables common to hospital medicine.

took place and particular issues raised in relation to the proposed
intervention or procedure.
Objective: To determine how effectively the documentation of
informed consent is carried out at a busy Australian teaching
hospital.
Aims: To identify areas where documentation is lacking and
propose how shortcomings, if any, may be addressed.
Methods: Caesarean section is a common operation at Flinders
Medical Centre (FMC) (approximately 75–100 operations
monthly). Through an audit of 101 case files of women who
underwent caesarean sections at FMC in August and September of
2011 (50 emergency, 51 elective) we examined how informed
consent was documented.
Results: Two of the 101 files did not contain any written evidence
of consent. An average of 4.2 (range 2–6) maternal risks out of a
possible seven were recorded for each elective case and average of
3.3 (range 0–5) maternal risks were recorded for each emergency
case. Risks to future pregnancies in the elective group were
recorded on average 0.3 of 3 (range 0–2) and 0.2 (range 0.1) risks
were recorded in the emergency group. Over the two groups 75%
(76) of the cases didn’t have a single risk to future pregnancies
recorded. A record of written information being given was
recorded in 16% (8) of elective cases and in only 2% (1)
emergency cases. Procedures that were not to be done were
recorded in three of the emergency cases and in none of the
elective cases.
Conclusion: The documentation of informed consent is
universally poor across all of the examined categories. A
structured consent proforma may facilitate the recording of
informed consent.

Alabama School of Medicine Division of Preventive Medicine;3 University of Pittsburgh School of Medicine; 4 University of
Minnesota School of Public Health; 5 Kaiser Permanente Medical Care
Program; 6 Division of Research, Kaiser Permanente
Objective: Prematurity is largely a condition of unknown cause,
although a handful of studies have related it to pre-pregnancy
cardiovascular risk factors including hyperlipidemia, diabetes, and
self-reported hypertension. No studies to date have assessed pre-
pregnancy blood pressure measurements in connection with
prematurity and thus it was our objective to do so.
Methods: CARDIA is a multi-center, prospective observational
study of risk factors for coronary heart disease in young black and
white men and women. Of the 2787 female participants enrolled
in 1985–1986 aged 18–30, 1301 were evaluated who had a birth of
known, self-reported gestational age after the baseline visit and
had blood pressure measurements prior to that subsequent birth.
One hundred sixteen had early preterm births (<34 weeks of
gestation) and 304 had late preterm births (34–37 weeks of
gestation). Logistic regression models adjusted for covariates
including race, recruitment center, and education measured at
baseline; as well as parity, time between blood pressure measure
and conception, and BMI measured at the visit prior to the index
pregnancy; and finally age at delivery.
Results: The highest quartile (range 111–165 mmHg) as
compared to the lowest quartile (range 84–98) of the systolic
blood pressure closest to conception was significantly associated
with early preterm birth (adj OR 1.86, 95% CI 1.01, 3.44) and late
preterm birth (adj OR 1.56, 95% CI 1.03, 2.34). Additional
adjustment for a self-reported pre-pregnancy diagnosis of
hypertension and for self-reported gestational hypertension only
modestly attenuated the relationship with both early preterm (adj
OR 1.81, 95% CI 0.97, 3.36) and late preterm births (adj OR 1.46,
95% CI 0.96, 2.20). Neither diastolic blood pressure nor mean
arterial blood pressure were consistently elevated among women
bearing early and late preterm births. Whereas neither race nor
parity interacted with blood pressure to elevate preterm birth risk,
obesity exaggerated the link (adj OR 14.32, 95% CI 1.55, 135.10)
and the association was unapparent in non-obese women.
Conclusions: These results suggest that pre-pregnancy systolic
blood pressure in the presence of obesity elevates the risk for both
early and late preterm birth.

Transabdominal cervical suture for the preventionof pregnancy loss: the next 42 cases
Gibb, D
The Birth Company, London, United Kingdom
Objective: To assess the performance of Trans Abdominal
Cervical Suture by a single surgeon in the management of high
risk pregnancy over a 16 year period between 1996 and 2012. A
previous series of 50 cases were published in BJOG in 1995 by the
same surgeon.
Methods: Cases were recruited in a referral practice. Almost all of
them had suffered one or more mid trimester pregnancy losses or
premature births between 18 weeks and 32 weeks of gestation.
Some cases had previous failed trans vaginal suture but the
majority had losses following previous surgery for pre-malignant
cervical disease. Open surgery by laparotomy was undertaken as
soon as possible after 11 weeks of gestation except one which was
a pre pregnancy procedure. General anaesthesia was used and the
operative technique was that described by Gibb and Salaria
(1995). Mersilene tape was used. A short video clip will be shown.
The patients stayed in hospital for about 72 h after the procedure.
No antibiotics or tocolytics were used. The women then had high
risk pregnancy surveillance but this did not involve trans vaginal
ultrasound scans or adjunctive therapy. When the fetus reached
maturity delivery was undertaken by caesarean section. The suture
was left in place and some patients proceeded to future
pregnancies.
Results: Forty-two operations were perfomed: 28 operations were
performed in London, eight in the UK outside London and six

abroad. There were three twin pregnancies. Thirty-nine
pregnancies have been delivered after 36 weeks with a successful
outcome including the three sets of twins. In one case the
anomaly scan revealed a fetal malformation and the patient opted
to terminate the pregnancy. In a second case the patient had
experienced previous uterine scar dehiscence and suffered
abdominal pain and anxiety during the rest of the pregnancy after
the suture insertion. On account of the symptoms she had to be
delivered at 32 weeks: the child survived intact and is healthy.
One case is ongoing at 28 weeks of gestation. There was a 100%
success rate of intact survival for normally formed babies.
Conclusion: The role of Trans Abdominal Cervical Suture has
been further clarified. Almost all these women who had very poor
reproductive histories went on to have at least one healthy child.
Study is now required on the place of pre pregnancy
transabdominal cervical suture and cervical suture by a
laparoscopic technique.

The decision delivery interval in emergencycaesarean sections and its correlation withperinatal outcome: evidence from 204 deliveries
Singh, R; Deo, S; Pradeep, Y
Professor Department of Obstetrics and Gynaecology, Chhatrapati
Shahuji Maharaj Medical University (erstwhile KGMU), Lucknow,
India
Objective: To determine the decision to delivery intervals in
emergency caesarean sections and its correlation with the perinatal
outcome.
Methods: It was a prospective observational study over 6 month
period in a tertiary care teaching hospital. Consecutive cases with
live singleton pregnancy undergoing emergency caesarean sections
were included. The primary outcome measure was decision to
delivery intervals and perinatal outcome in terms of 5 min Apgar
score, neonates requiring admission to neonatal intensive care
unit and perinatal deaths. Maternal demographic profiles,
indication for caesarean section, type of anaesthesia were the
secondary outcome measures. Data was analysed using SPSS
version 13.0. Chi square test was used to compare difference in
proportion between the two groups. One way ANOVA was used
to compare the difference in Apgar score and decision to delivery
intervals. For analysis we divided the groups into 30 min decision
delivery intervals(£30, 31–60,>60 min). P value of < 0.05 was
significant.
Results: Over the period, 204 women underwent emergency
caesarean sections. The mean age of women was 26.8 ± 4.6 years.
The mean gestational age at delivery was 38.0 ± 3.0 weeks. The
mean decision delivery interval in the cohort was 42.5 ± 19.4 min.
The decision delivery interval of £30 min was achieved in 19% of
the deliveries; another 60% deliveries were achieved within
60 min, while the remaining 21% delivered after 60 min. There
was no significant difference in the perinatal outcome between
babies delivered within 30 min and 31–60 min of decision
delivery intervals. However, there was a significantly higher risk
for poor perinatal outcome for babies with decision delivery
intervals of > 60 min [OR-6.9, 95% CI: 2.37–20.18].
Conclusion: The perinatal outcome between decision delivery
interval of £30 and 31–60 min was statistically not different,
however the £30 min decision delivery interval should remain as
the gold standard.

Health Bureau, Ministry of Health, Sri Lanka
Introduction: One of the leading causes of maternal mortality in
Sri Lanka for the last two decades has been pregnancy induced
hypertension (PIH). Disparities between high attendance rates at
field clinics and high maternal deaths from PIH raise questions
about the quality of detection of PIH in field antenatal clinics.
Improving the detection rate of PIH could help Sri Lanka in
reducing maternal mortality to a single digit.
Objective: To describe the quality of detection of PIH in pregnant
women in the field antenatal clinics of Sri Lanka.
Methods: A cross-sectional study design was used. In the
Colombo district, of the 11 MOH areas, according to the Lot
Quality Assurance Sampling method, five field antenatal clinics
were randomly selected (n = 55 clinics). In each of these clinics,
five women in their booking visit (n = 275 women) were sampled.
A checklist was used to observe and the following indicators were
used to assess the quality of services. History and clinical
examination, measuring the BP, explaining the findings,
investigation for urine albumin, explaining the results of the
investigation.
Results: Due to the unavailability of the doctor in 12% of clinics,
a history, a clinical examination and the BP measurement could
not be performed in 60 (21.8%) women. A history was obtained
in only 8 (2.9%) women and a clinical examination with regards
to diagnosis of PIH/PET was performed in 48 (17.5%) women.
Among the women whom were seen by the doctor at the clinic,
the BP was measured in 185 women (86%). Only 1/3 of these
measurements were according to standards. The blood pressure
readings recorded on the pregnancy card was compared with
results of the principal researcher. The sensitivity for systolic BP
and Diastolic BP was 57.1% (95% CI: 47.4% -66.8%) and 16.7%
(95% CI: 9.4% -24%) respectively. The urine albumin was
investigated according to standards in 7% of the women. The
quality of services was unacceptable in all the MOH areas for four
of the six indicators.

Fetal fibronectin rapid test versus phosphorylatedinsulin-like growth factor-1 (phIGFBP-1) as bedsidetest kits for prediction of preterm delivery in theclinical setting
Thandayathany, V; Yassin, MAJM; Omar, MH;
Ismail, NAM; Tamil, AM; Kampan, NC
Hospital Universiti Kebangsaan, Malaysia
Objective: The objective of this study is to compare
Phosphorylated insulin-like growth factor-1 (phIGFBP-1) test and
fetal fibronectin (fFN) test in the prediction of preterm delivery.
Methods: All patients between the gestations of 24–34 weeks
with documented contraction on the cardiotocography were
recruited. phIGFBP-1 test and fetal fibronectin test were done
on all patients. The fetal fibronectin test results were blinded
and the patient was managed as per standard protocol for
preterm delivery. The administration of tocolysis, steroids and
antibiotics were based on clinical judgement of the attending
obstetrician. The outcome of pregnancy and delivery were
analysed.
Results: One hundred and seventy four patients were recruited.
The negative predictive value for phIGFBP-1 test was 97.3, 94.0,
89.3, and 92.0 for 48 h, 7 days, 14 days and £34 weeks
respectively. The NPV for fFN test was 96.7, 92.7, 88.0, and 90.6
for 48 h, 7 days, 14 days and £34 weeks respectively. The mean
gestational age at delivery was 35.8 ± 3.81 weeks for women with
positive phIGFBP-1 test and 36.5 ± 3.54 weeks for women with a
positive fFN test. For women with both tests positive, the mean
delivery was 35.8 ± 3.62 weeks. The delivery interval from initial
presentation was 2.16 weeks shorter in women with phIGFBP-1
test positive as compared to women with negative phIGFBP-1 test
(3.67 vs. 5.83 weeks). It was 1.8 weeks shorter in women with fFN
test positive than those with negative FfN test (3.96 vs.
5.77 weeks). Both phIGFBP-1 and fFN test have high negative
predictive value in predicting risk of preterm delivery. Both the
test had a fair kappa agreement i.e 0.21–0.40. The area under the
curve for phIGFBP-1 test and fFN test is 0.766 and 0.720
respectively.
Conclusion: Both phIGFBP-1 and fFN test are good diagnostic
tools in prediction of preterm delivery. A negative phIGFBP-1 test
or fFN test will confer that the patient has a 92.7% to a 94%
changes of not delivering in the next 7 days. phIGFBP-1 test may
be a better diagnostic tool with higher negative predictive value,
longer delivery interval and a higher kappa agreement.

Psychological issues in reproduction – why itmatters
Chung, T
The Chinese University of Hong Kong, Hong Kong, China
In many countries, suicide has become the post common cause of
maternal death. This is especially so in countries where historical
causes of maternal mortality such as haemorrhage, infection and
severe hypertensive disease have been mitigated to a large extent.
However, where there is reasonable investment by governments in
maternal health, there is a accelerating trend in reduction in
maternal mortality even in relatively resource poor countries. It is
reasonable to anticipate that mental health causes of maternal
mortality will become more prominent and will need preparation
and planning in order to address this. A 15 year experience
describing initial research and implementation of a service
programme using local research will be presented. Potential future
developments will be discussed.

Department, Cairo, Egypt
Objective: Fetal DNA has been found in maternal serum.
Diagnosis of fetal gender using maternal serum has been
attempted in an effort to develop a new non-invasive method of
prenatal diagnosis.
Methods: Peripheral blood samples were obtained from 25
Egyptian pregnant women at 9–12 weeks of gestation. DNA was
extracted from 800 lL of each serum sample. To detect Y-
chromosome-specific sequences DYS14 in the maternal serum, 40
cycles of PCR were carried for each DNA extract. The PCR
products were analysed by 2.5%agarose gel electrophoresis and
ethidium bromide staining, and the results were compared with
the results of ultrasound scan which done at 21 weeks of gestation
for all the 25 pregnant women for determination of fetal gender.
Results: Ultrasound scan at 12 weeks of gestation revealed that 13
pregnant women had a male fetus and the remaining 12 women
had a female fetus. DYS14 was not detected in serum samples
obtained from any of the 12 women carrying a female fetus. Fetal
gender was determined successfully in all the 25 Egyptian
pregnant women. So our method had the highest sensitivity
(100%) reported to date.
Conclusion: PCR analysis of maternal serum can be used to
diagnose fetal gender in first trimester.

Introduction: It has long been recognized that certain cardiac
predicting factors including pre-pregnancy NYHA class, poor left
ventricular function, presence of pulmonary hypertension or
cyanosis, outflow tract obstruction and prosthetic valves adversely
influences pregnancy outcome.
Objective: The primary objective of this study was to determine
the incidence of cardiac events amongst pregnant women with
cardiac disease in HUSM. The secondary objectives were to
specifically indentify incidence of primary and secondary cardiac
events in the studied population, to identify presence of
CARPREG predictors amongst pregnant women with cardiac
disease, to formulate a risk stratification index for the prediction
of cardiac events during pregnancy and to look into neonatal and
obstetric outcomes in studied group.
Methods: A total of 200 patients aged 18 years old and above
with underlying or newly diagnosed cardiac disease were recruited
into this prospective cohort study. At entry, any presence of
cardiac event predictors was identified from history, physical
examination, ECG and echocardiography findings. Follow up data
were obtained during clinical visits. Data analysis using Chi-
square test followed by univariate analysis using Simple Logistic
Regression analysis. Following this, a Multivariate Logistic
Regression analysis was performed.
Result: The incidence of cardiac events among 200 studied
patients in HUSM was 14%. The incidences of primary and
secondary cardiac events were 9.5% and 7.0% respectively. Out of
total studied patients, there were 150 patients with no cardiac
event predictor, 41 patients with 1 cardiac event predictor and
nine patients with more than one cardiac event predictors.
Correlation between occurrence of cardiac event and number of
cardiac event predictor which were analyzed using Chi-square test,
simple logistic regression and multiple logistic regressions, had all
consistently shown presence of cardiac event predictor would
strongly predict occurrence of cardiac event (all with P < 0.001).
The risk of cardiac event in pregnancies with 0, 1 and >1
predictors were estimated to be 2%, 43.9% and 77.8%
respectively.
Conclusion: This study had shown that the incidence of cardiac
events was almost similar as estimated during the beginning of
study when the sample size was calculated (14% vs. 13%). The
number of cardiac event predictor(s) identified at entry were
highly predictive of occurrence of cardiac events. This can be put
up as risk stratification index to identify those patients who are at
high risk of developing cardiac events during the prepartum,
peripartum and postpartum period.

Objective: Currently there are few studies that may clearly
establish scientific criteria for diagnosis of labour. We conducted a
prospective cohort study to evaluate if metabolomic analysis of
urine samples collected from term pregnant women could
represent a new tool for diagnosis of labour.
Methods: Urine samples were collected from 45 women with
physiological singleton pregnancy at 37–42 weeks of gestation
referred to our delivery settings for term pregnancy monitoring or
admitted for labour. Written informed consent was obtained from
each woman. After aliquoting samples were stored at )80 �C.
Urines were chemically analysed by means of GC/MS and 1H-
NMR techniques as described before.1 Data matrix generated by
these procedures were analysed by means of PLS-DA models
(Partial least squares discriminant analysis; SIMCA-P+ version
12.0, Umetrics, Sweden) to test the hypothesis of the
discriminating power of urinary metabolites concentrations as
labour starts. The analysis on the variables of primary importance
in this separation was applied to evaluate the set of discriminating
metabolites.
Results: PLS-DA models from both 1H-NMR and GC/MS
analysis were able to discriminate between the pregnant women in
labour state (n = 20) from the ones far from the delivery (n = 25)

The impact of body mass index on maternal andneonatal outcomes: a retrospective study of 30 298singleton pregnancies in a tertiary referral hospitalin Northern Ireland, 2004–2011
[1.4 (1.3–1.5), 1.8 (1.7–2.0)]; and macrosomia [1.5 (1.4–1.6), 1.9
(1.7–2.1)], with risk for all outcomes increasing for obese class II
and III. Conversely, as BMI increased, there was decreased
likelihood of achieving a vaginal birth or successful breastfeeding.
In addition, women with a BMI of 40 or over had an increased
risk of having a preterm birth [1.6 (1.2–2.3)], stillbirth [3.1 (1.3–
7.2)], a baby with low Apgar scores at 5 min [2.0 (1.3–3.2)], a
baby admitted to the neonatal unit [1.6 (1.2–2.4)], a longer
postnatal stay [2.0 (1.5–2.6)] and a wound problem following
caesarean section [4.9 (2.9–8.0)].
Conclusion: This study highlights that obese women and their
babies are at increased risk of adverse maternal and neonatal
outcomes, with the risk of adverse outcomes increasing across
BMI categories. While those women with the highest BMI are at
greatest risk of having an adverse outcome, it is essential to plan
adequate care for all women with an elevated BMI, from the
overweight through to the highest obese categories.

A simple classification system for maternaltraumatic injuries associated with second stagecaesarean section
Angala, P; Raja, M; Ikomi, A; Varma, R
Basildon and Thurrock University Hospital, United Kingdom
Introduction: Incidence of caesarean section (CS) deliveries is
increasing in the developed world. The obsolete status of high
cavity instrumental delivery and concurrent reduction in overall
instrumental rates in UK units suggest a rising rate of CS at full
dilatation. A recent UK study showed 15.3% of emergency CS
were performed in the 2nd stage. CS at full dilatation is a
technically demanding procedure and has an association with
complications of intra-operative trauma (high rates of laceration
injuries to uterus, cervix and vagina). This is reflected in the most
recent Scottish Morbidity data (2009) which shows 25% of
women delivered by emergency CS and experiencing massive
obstetric haemorrhage (MOH) were delivered in the 2nd stage of
labour. 16.3% of all the MOH cases were caused by extensions of
the uterine incisions and/or broad ligament haematomas at the
time of CS. It is surprising that to date a universally accepted
formal classification system for maternal injuries (similar to that
of obstetric anal sphincter injuries) relating to this scenario, has
failed to emerge.
Aim: To design a simple classification system and apply this in a
review of second stage deliveries. Setting A UK district general
hospital
Method: A retrospective analysis of 60 patients from January to
September 2010 (9 months). The data was collected by analysing
the labour and operation notes. All the patient who had CS at full
dilatation were included in the study. The complexity of suturing
of uterine incision was graded with grade 1 being uterine incision
that were easy to suture and did not increase the operating time
Grade 2 being those wich increased operating time and total
blood loss. Involvement of cervix, vagina, bladder in the uterine
incision and need for senior help was graded as Grade 3
Results: Uterine incision extension was noted in 25% of these
patients and of those 53.3% were Grade 1,Grade 2 were 26.6%
and 20% were Grade 3
Conclusions: To the best of our knowledge, this is the first
reported classification system relating to this clinical scenario and
in our hands has proved to be a useful tool for audit. It offers a
grading based not only the extent of the damage but also on the
effort required to treat. With further validity development
(ongoing) potential applications include as a research tool and as
a reproducible method for improving the quality of
contemporaneous documentation for this high risk episode.

UK obstetrician’s response to the NICE and RCOGguidelines on antenatal thrombo-prophylaxis – asurvey and an audit

Objective: The National Institute for Health and Clinical
Excellence (NICE) and Royal College of Obstetricians and
Gynaecologists (RCOG) guidelines do not give any clear advice
for most prenatal venous thromboembolism (VTE) risk scores.
There have been no randomised control trials for administering
Low Molecular Weight Heparin (LMWH) antenatally as
thromboprophylaxis for modest scores. There were no venous
thromboses or pulmonary embolism events in the two trials where
LMWH was administered in the women with recurrent
miscarriages (SPIN, Kaandorp et al. 2010). Therefore there is no
evidence base for administering heparin antenatally. Hence for
pregnant women, without a previous VTE and thrombophilia,
with a score above two risk factors, the guidelines rightly say
‘consider antenatal heparin’. We measured how many pregnant
women in UK had a VTE score above 2, and how many UK
obstetricians responded to this risk score and administered
heparin antenatally.
Method: A web-based survey was done, where a questionnaire
was sent to 600 obstetricians who are members of the British
Maternal and Fetal Medicine Society (BMFMS). This comprised
of ten hypothetical scenarios in which the respondents were asked
whether they would prescribe LMWH for these antenatal patients.
The VTE score of each scenario was three or above, and therefore
LMWH should have been considered. In addition, a retrospective
audit of 265 women, who delivered in January 2012 in a UK
teaching hospital was completed. Case notes were reviewed to
identify those who had three or more risk factors antenatally.
Results: Seventy two obstetricians responded to the survey. The
number of obstetricians, who would prescribe LMWH ranged
from 22 (31%) for a 36 years old lady with a BMI of 35 and who
is in her 4th pregnancy to 68 (94%) for a 37 years old paraplegic
woman with a BMI of 36. For most (seven out of 10) scenarios
half or more of the obstetricians would give LMWH antenatally.
In the audit, 18 of 265 patients (6.8%) were found to have three
or more risk factors for VTE at their booking visit.
Conclusion: Our survey suggests most of these obstetricians
would respond to the NICE/RCOG guidelines by prescribing
heparin antenatally. Assuming our audit sample is representative
of other units in UK, over 49 000 pregnant women are considered
for antenatal LMWH every year. This suggests that a very large
number of pregnant women in UK are likely to receive antenatal
thromboprophylaxis in absence of any trials.

Introduction: Human milk is one of nature’s most extraordinary
fluids, perfectly balanced to meet all of the nutritional,
developmental, and protective needs of the newborn infant. In the
last 30 years, as our understanding of the importance of
breastmilk and pregnancy and lactation occur within the context
of a woman’s breastfeeding have grown, so has the number of
women who have made the decision to breastfeed As virtually all
pregnant and breastfeeding mothers will at some time require
medication, this means that more mothers and their infants will
be exposed to medications. Questions about the use of certain
medications during breastfeeding concern both women and their
health-care providers. Unfortunately, far too many women
discontinue breastfeeding on the advice of well-meaning but
misinformed physicians, nurses and pharmacists.
Physians, nurses and pharmacists can play an important role in
the promotion of breastfeeding and in supporting mothers who
are breastfeeding. To be effective, pharmacists must overcome
several obstacles: Most pharmacists have received little instruction
on the topic of medications and breastfeeding. There is a tendency
to focus on theoretical drug toxicities rather than the real risks of
not breastfeeding. There is confusion between the risks of
medication use during pregnancy versus medication use during
breastfeeding. Misleading or incorrect information is common.
The Physicians’ Desk Reference (PDR) is the poorest source of
information. Most medications are safe for breastfeeding mothers
and their infants. As not breastfeeding carries significant risks for
both mother and infant, recommending that a mother stop
breastfeeding to take a medication is almost never required and
should only be done as a last resort.
Medication Classification Systems: To assist clinicians to better
assess risk versus benefit for specific drugs and drug groups,
classification systems have been offered. The American Academy
of Pediatrics 23 lists drugs in tables as summarized in Table 3,
with most medications in the extensive ‘compatible with
breastfeeding’.
Conclusion: Overall health, with breastfeeding women
experiencing both acute and chronic conditions needing
treatment. It is critical that the effects of medication use during
lactation be evaluated and the information made readily accessible
to both women and health-care providers, especially Physicians
and pharmacists. This allows all to make informed decisions
about the use of medications during lactation and the
management of maternal and infant conditions. Without
evidence-based counseling, women may undermine their own
health by discontinuing needed medications.

An interdisciplinary analysis of emotions in thecontext of prenatal diagnosis of Down syndromeand choice of medical termination of pregnancy:the perspective of couples and healthcareprofessionals
Broussin Ducos, A
Departement d‘ethique appliquee, Universite de Sherbrooke, Canada
The prenatal diagnosis (PND) is used to identify the fetal
anomalies. In the case of a PND of Down syndrome (DS),
Health professionals (HPs) announces the irreversible nature of
the anomaly. The couples are faced with the options to terminate
the pregnancy or not and confronted with negative emotions. If
couples choose the termination of pregnancy (TOP), they and the
HPs are here confronted with the symbolic violence of feticide
A review on the various aspects of the PND of DS and emotions
felt by the French, Canadian american couples/HPs concerned
allowed me to develop a conceptual grid analysis which served me
to identify the emotions, their role and consequences on the
wellbeing of couples/HPs concerned by these PND/TOP.
Results: From various perspectives: Psychological: These PND of
DS/TOP generate various emotions: guilt, shame, anger, hate,
regret, fear, anguish, remorse, denial and sadness which cause
psychological/physical damages in the context of their over-
expression. Clinical: TOP categorisation grids containing the
emotions and personalities who experience them should help
psychologists to identify those who run a significant risk of
developing depression Sociopolitical: A comparative analysis of
the emotions experienced by couples/HPs from different countries
demonstrates that the emotions,their intensity differ according to
societal values and public health organisation. Ethical: The couples
disinvest emotionally the fetus for decision making. The feticide
causes the emergence of hidden feelings, generates trauma, casts
doubts on the well-founded of the decision of TOP, undermines
the wellbeing. The DPN/TOP allows to grasp how it’s important
to consider the emotions during the decision-processes and the
importance of compassion/empathy.
