2. Why focus on preventing
post-partum hemorrhage?
Haemorrhage is the largest direct cause of
maternal death
PPH is mostly unpredictable
Most PPH is caused by uterine atony
Evidence-based, feasible, low-cost
interventions exist
Active management at the third stage of
labour can prevent 60% of PPH
3. Difficulties associated with comparing
post-partum hemorrhage studies
Method to determine blood loss
– Visual underestimation 70–80%
Conduct during third stage of labour
Confounding factors in epidemiological
studies
58% of trials do not report their definition
of PPH
4. Maternal Health:
some ( underestimated) statistics
180–200 millions pregnancies per year
75 millions unwanted pregnancies
50 millions induced abortions
20 millions unsafe abortions
358,000 maternal deaths (1000 per day)
1 death every 1,5 min
20 maternal morbidities per minute
10-15 millions disabilities each year
WHO, 2010
5. Maternal Death Clock
380 women become pregnant
Every Minute... 190 women face unplanned or
unwanted pregnancy
110 women experience a
pregnancy related complication
40 women have an unsafe
abortion
1 woman dies from a pregnancy-
related complication
20 women suffer of a disabilty
related to childbirth

hemorrhage?
Excess blood loss
after the birth of a
baby
PPH >500 ml (3.5–
30%)
Severe PPH >1000 ml
(1.5–5.0%)
Immediate PPH:
– Onset within 24 h of birth
These definitions are notPPH late:
accepted by all!!
– Onset after 24 h of birth

Placenta Previa/Accreta and Prior Cesarean Section
STEVEN L. CLARK Et al
The risk of placenta previa was 0.26% with an
unscarred uterus and increased almost linearly with
the number of prior cesarean sections to 10% in
patients with four or more.
With a placenta previa and one previous cesarean
section, the risk of placenta accreta was 24%; this
risk continued to increase to 67% (two of three) with
a placenta previa and four or more cesarean
sections.
29. Joint statement management of the third stage
of labour to prevent post-partum hemorrhage
Active management of the third stage of labour should be offered to
women since it reduces the incidence of post-partum haemorrhage
due to uterine atony
– Consists of interventions designed to facilitate the delivery of the
placenta by increasing uterine contractions and to prevent PPH
by averting uterine atony. The usual components include:
Administration of uterotonic agents
Controlled cord traction
Uterine massage after delivery of the placenta, as
appropriate
Every attendant at birth needs to have the knowledge, skills and
critical judgment needed to carry out active management of the third
stage of labour and access to needed supplies and equipment

S: transfer the patient to the operating room
( exclude trauma or retained products, proceed with bimanual
compression)
57. TAMPONADE WITH
BAKRI BALLOON
– Simple and efficient (87-95 % success rate)
– Applicable after cesarean and vaginal births
– Used as method of prevention in “cesareans at high
hemorrhagic risk” (placental pathologies, uterine
over-distension, preeclampsia, precedent
hysterotomy, coagulopathy, etc) and in the case of
contraindications for prostaglandins (asthma,
glaucoma, important hepatic and renal dysfunction)
– Easy to insert and remove
– Continuous monitoring of blood loss
58. BAKRI BALLOON
The Bakri is a balloon in silicon, latex-free, which is filled
with physiological solution (500 cc max) and is able to
create a real intrinsic compression on the myometrial
walls: the filling volume can be varied in relation to the
dimension of the uterus and the contractile response
Additionally to the ease of insertion it has the
possibility to monitor the amount of blood loss
thanks to the drainage holes located in the distal part of
the catheter, which is attached to a sac in order to
collect the fluids. This access is used also to perform
washings of the uterine cavit y.
Associate adequate antibiotic coverage

For each woman who dies during pregnancy, 30 women suffer complications. Initiatives should include: Family planning Management of complications of abortion Management of complications of pregnancy and childbirth
From Evolution to ancient oxytocics 3.5 thousand years ago, Egyptians were fully aware of the current problem: If you could promote uterine contraction, you would speed labour and stem haemorrhage. Papyrus Ebers recommends various recipes, like… … Fly excrement is even mentioned in various ancient pharmacopoeias. 100 AD Discorides a Greek physician lived at Nero’s time recommends cyclamen, a flower. 1600 anno domini, Gerad a British herbalist advices chervil, a pot herb. This all has nothing to do with an OT agonist, I do not know, if it works, but it concerns exactly the same life threading indication! Finally ergot came up, extracts and alkaloids from a fungus on rye. Longer used than OT, it causes strong uterine contraction, abortions, but is more toxic: nausea, vomiting, and hypertension
About 60 years ago, OXT was synthesised by Vincent du Vigneaud, an American biochemist. Driven by his interest in sulphur containing amino acids he managed to isolate OXT and ADH from crude pituitary preparations. He identified the structure of the nona-peptide. Here a chromatogram shows separated amino acids of the hydrolysate and an identical chromatogram from a mixture of artificial amino acids. He succeeded with the synthesis of the first polypeptide hormone, put the amino acids together in the right sequence, closed the ring and finally proved chemical properties and physiological activity. The most thrilling experience: The synthetic polypeptide and the natural product were identical. At that time, it wasn’t taken for granted that synthetic and natural products behave chemically and pharmacologically identical.
Today, OT alone or in combination with ergometrin is globally available. However there are regional differences regarding the recommended use. The slide is not complete and does not mean OT is always the treatment of choice. It is described in monographs of several pharmacopoeias such as… Most known brands are Syntocinon from Novartis, Pitocin from Pfizer etc. However some of the products have been withdrawn form the markets. There are two major indications: OT infusions are useful to induce and augment labour. For PPH it is used alone or in combination with ergometrin. And there are additional indications such as: OT injected in umbilical cord vein to assist removal of a retained placenta. In the past, as nasal spray with good BA was used, it can induce lactation. OT challenge test to detect placental insufficiency and still birth risk: OT is infused in third trimester and the baby is monitored for heart rate anomalies. Finally in abortion it plays probably more a theoretical than practical role.
The next slide is dedicated to OT agonists. Carbetocin it is a long-acting synthetic analogue of OT. It contains a thioether instead a disulfide bridge, it lacks an amino acid - cysteine 1, and a phenol alcohol is blocked by a methyl ether. It is used for treatment of uterine atony following Caesarean section and in veterinary medicine. To my knowledge this is the only therapeutically or commercially relevant oxytocin agonist. An incredible number of OT derivatives have been synthesized, from different companies, from universities, from professors Manning +others some are published/patented, but I am not aware that any of them reached great relevance so far. However, there are some experimental peptides published like hydroxy threonine OT And more recently there is again activity in non-peptide, central agonists such as the following: There is a series of compounds patented for erectile dysfunction and from Wyeth-Ayerst a series for treatment of anxiety and schizophrenia-related diseases. Another series including compound 39 from ex-Ferring UK.
