PPH Problem:
Living in the shadow of The Taj Mahal
●The majority of these deaths occur within 4 hours of
delivery.
●Probably accounts for more than 30-38% of all
maternal deaths.
● Deaths from hemorrhage could often be
avoided.
●PPH is generally defined as blood loss greater than
or equal to 500 ml within 24 hours after birth.
● Severe PPH is blood loss greater than or equal to
1000 ml within 24 hours.
●When I gave birth to my 4th child, I suffered PPH. I
almost lost my life. I was lucky to be under the care of
trained health care personnel.
Then I started wondering what was happening to rural
women.

EXPECT PPH IN THE
MOST UNEXPECTED
SITUATION !
NEVERTHELESS…
PPH - PREPARE
“Perhaps the most important aspect in the management of PPH
is the attitude of the attendant in charge. It is critical to maintain equanimity in what
can be a chaotic and stressful environment”.
PPH is an emergency which kills fast..
(golden hour)so we have to be ready and prepared
●I- Infrastructure preparedness
●D- Drugs and injections and iv fluids
●E- Emergency trays and trolleys
●A- All together (Staff and team work)
Infrastructure
Drug kit, injections & iv fluids
Emergency trays and trolleys
●PPH may occur in women without identifiable
clinical or historical risk factors.
Active management of the third stage of labour
be offered to all women during childbirth to prevent
PPH.
PPH—HANDLE
(i)Administration of a uterotonic soon after the birth of the baby;
(ii) Clamping of the cord following the observation of uterine contraction (at
around 3mins)
(iii) Delivery of the placenta by controlled cord traction, followed by uterine
massage
(i) (ii) (iii)
Benefits of AMTSL
●Uterine atony accounts for 70-90% of all PPH cases
AMTSL reduces:
- Incidence of PPH by 60%
2018
To effectively prevent PPH, only one of the
following uterotonics should be used:
•Oxytocin
•Carbetocin (Newer molecule)
•Misoprostol
•Ergometrine/methylergometrine
•Oxytocin(5U) and ergometrine(0.5mg) fixed-dose
combination.
Oxytocin : current standard of care.
●Route : IM, Infusion,
●Dose: 5-10 units in 500 ml crystalloid.
●Max dose : 40 units.
●Intravenous (IV): almost immediate action with peak
concentration after 30 minutes
●Intramuscular (IM): slower onset of action, taking 3–
7 minutes, but produces a longer lasting clinical
effect of up to 1 hour.
Continued..
●Short plasma half life : 1-6 mins.
●Continuous IV infusion required at LSCS.
Side effects: Hypotension(rapid iv bolus),water
intoxication(large doses)
●Storage at 2–8 °C to prolong shelf
life.
● Requires protection from light,
Oxytocin Ban !
Methergine
●Sustained tonic uterine contraction.
●Route : IM/slow IV.
●Dose : 0.2 mg repeat 15 min followed by 4
th hourly.
●max dose : 5 doses( 1 mg).
●IV: onset of action within 1 minute, lasting 45
minutes (although rhythmic contractions may persist
for up to3 hours)
● side effects : nausea,vomiting,diarrhoea.
●Storage : 4 degrees.
Injectable prostaglandins (carboprost or sulprostone)
are not recommended for the prevention of PPH
Carboprost should not be given IV- can be fatal.**
Misoprostol
●Synthetic analogue of PGE1
●Dose : 400-600 mcg.
●Max : 1000 mcg.
●Half-life: 20–40 minutes.
●Absorbed 9–15 minutes after sublingual, oral, vaginal
or rectal use
●No clear evidence of which dose is superior, but higher
doses have more side effects.
●Can be used in hospital or community
●Side effects : shivering, fever ,diarrhea.
●Stable at room temperature , easy to administer ,
cheap.
Carbetocin
●Sold as Duratocin. Rate varies from
18-40 euros. (Approx. 1500 - 3400 INR.)
It is a patented drug researched and developed by
Ferring. The company has committed to the WHO to
make the product available in the market at same
price as oxytocin.
●MOA: Binds to oxytocin receptors in the uterine
smooth muscle, resulting in
-rhythmic contractions
-increased frequency of existing contractions
-increased uterine tone
●Dose : iv bolus 100mcg , acts within 2 min.
●IV: sustained uterine contractions within 2 minutes,
lasting for about 6 minutes and followed by rhythmic
contractions for 60 minutes
●IM: sustained uterine contractions lasting for about
11 minutes and rhythmic contractions for 120
minutes
Continued..
●Peak concentration < 30 min.
●Longer half life : 80-90 min. 80% bioavailability.
●Carbetocin is intended for single administration only.
No further doses of carbetocin should be administered
for prevention of PPH.
●Storage:
-It is in heat stable formulation,
-does not require cold chain transport and storage .
-can stay at room temperature for a long period of
time
30°C for 3 years,
40°C for 6 months,
50°C for 3 months,
60°C for 1 month.
Continued..
●Carbetocin has similar desirable effects compared with
oxytocin though it may likely be superior to oxytocin in
reducing
-PPH of at least 500 ml
-use of additional uterotonics
Based on the WHO CHAMPION trial results
Carbetocin is recommended for PPH prevention,
especially in those settings where the cold storage
of oxytocin is not possible
Tranexamic acid
●Tranexamic acid is an antifibrinolytic agent.
●During elective surgery tranexamic acid reduced the risk
of blood transfusion by 39% .
●WHO Recommendations:
Tranexamic acid may be offered as a treatment for PPH
ONLY if:
(i) oxytocin, followed by second-line treatment options
and prostaglandins, has failed to or
(ii) it is thought that the bleeding may be partly due to
trauma
Recombinant factor VII a
●It involves enhancement of rate of thrombin
generation .
●Resistant to premature lysis.
●Effective in severe obstetic hemorrhage.
●Use of rFVIIa could be life-saving, but is high rates of
thrombotic events.
●r factor VIIa is expensive and difficult to administer.
●Cost is 20000 -30000 Rs
Hemorrhage is often not recognized
●Blood loss is underestimated because in pregnancy
signs of hypovolaemia do not show until the losses are
large
●Mother can lose up to 30-35% of
circulating blood volume (2000 ml) before
showing signs of hypovolaemia.
●Slow steady bleeding can be fatal.
●Most deaths from hemorrhage seen after 5h
Q mat/ blood collection mat
• Named after - Dr. Md.
Abdul Quaiyum, is placed
under a woman immediately
after the delivery of a baby.
•The mat can retain 448±58
ml of blood when fully
soaked, signaling the
woman is hemorrhaging.
Bimanual Compression of Uterus
Compression of Abdominal Aorta
Apply downward pressure with
closed fist over abdominal aorta
directly through abdominal wall.
-With other hand, palpate femoral
pulse to check adequacy of
Compression
Pulse palpable = inadequate
Pulse not palpable = adequate
Maintain compression until bleeding is
controlled.
Signs in hemorrhagic shock-
● Pallor
● Confusion
● Increased HR (1
st sign )
Severity of shock-
A fit woman , who has delivered recently will not usually
decompensate untill 35%
of total blood volume has lost.
Rule of 30 and Shock Index
●30% blood loss >moderate shock
●Pulse rate – increase >30 bp
●Respiratory rate >30/min
●Systolic BP – drop by 30 mm Hg
●Urinary output < 30 ml/hour
●Hematocrit drop > 30% & to be kept at an absolute
value of > 30
●Shock Index = Pulse rate / Systolic BP
Normal = 0.5 to 0.7 : >0.9 indicates state of
shock that needs urgent resuscitation
Acute Postpartum Blood Loss
PROBLEMS:
Loss of circulatory Volume
Loss of O2 carrying capacity
Restore SaO2 O2 carrying capacity
Volume
1 – Crystalloid Supplemental O2 Transfusion
2 - Colloid
Fluid resuscitation-
How much fluid, How fast?
●Volume of 3x the estimated loss as crystalloids
(up to 4L) then as colloids
●Give blood early – mistake often
is too little too late!
●Replace as quickly as you can if patient shocked
●Be guided by the patients signs and response
(e.g. Pulse rate, BP,level of consciousness)
Volume replacement
●Aggressive fluid replacement should commence
to ‘catch up’ for any losses.
●Fluid of choice- Crystalloids over colloids.
●Crystalloid of choice- Ringer lactate, NS
●Fluid input & output charting.
●Loss of 1 L of blood requires 4-5 L of
crystalloids untill cross matched blood is available.
●Synthetic colloids are a ‘warning’ in modern
practice.
●No added benefits of colloids over crystalloids
seen. Even suggest possible worsening when
administered too early.
●But ideal choice- “Blood for Blood”
Medical Anti-Shock Trousers –MAST
(Pneumatic Anti-Shock Garments) -
●MAST are used to increase venous return to the
heart until definitive care could be given.
●MOA- combined with compression of blood
vessels, is believed to cause the movement of
blood from the lower body to the brain, heart
and lungs.
MAST-
Non-pneumatic anti-shock garment
(NASG)
●Low-technology first-aid device for stabilizing
women suffering hypovolemic shock secondary to
obstetric hemorrhage.
●It is a lightweight, re-usable lower-body
compression garment made of neoprene and Velcro
NASG
●MOA in hemorrhage & shock-
-Reversing shock and decreasing blood loss
thereby stabilizing the woman until definitive care is
accessed.
-Increases blood pressure by decreasing the
vascular volume and increasing vascular resistance
within the compressed region of the body, but does
not exert pressure sufficient for tissue ischemia
●The NASG is recommended as a temporizing measure
for PPH by the WHO and FIGO.
●It aids transport of hemorrhaging women
from rural areas to urban treatment centers, or while
awaiting procedures or surgery.
NASG
Panicker’s/Samartha Ramadas Vacuum Suction Hemostatic
Device for Treating Post-Partum Hemorrhage
●A specially made stainless steel or plastic cannula of
12 mm in diameter and 25 cm in length with multiple
holes of 4 mm diameter at the distal 12 cm of the
cannula.
●When introduced into the uterine cavity through the vagina
to reach the fundus.
●Cannula connected to a suction apparatus, and a negative
pressure of 700 mm Hg produced.
● Negative suction resulted in aspiration of all the blood
collected in the uterine cavity.
●Quantity of blood sucked varied from 50–300 ml . Collected
blood when completely sucked out, the bleeding ceased.
●Suction maintained for 30 min.
●Then the cannula taken out slowly after releasing the
suction after 20-30 minutes.
●No further bleeding from the uterine cavity, noted and the
uterus well contracted.
