PPH & Shock
Objectives
To detect PPH & assess degree of shock Identify types of PPH To develop skills and best practices for
management of postpartum hemorrhage To describe strategies for prevention of
postpartum hemorrhage
Haemorrhage is common
Most common cause of maternal death worldwide
Probably accounts for more than 30-38% of all maternal deaths
Deaths from haemorrhage could often be avoided
Haemorrhage 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 mls) before showing signs of hypovolaemia
PREVENTION STRATEGY FOR PPH
AMTSL: ACTIVE MANAGEMENT OF THIRD
STAGE OF LABOUR
The classical expectant management
• Wait for the natural forces of labor to bring about 3rd stage contraction and placental separation
• Look for the signs of placental separation• Controlled cord traction to expel the placenta
and membranes• Optional administration of Oxytocics
WHAT IS AMTSL :Active management of 3rd stage
• Oxytocic administration immediately after delivery of the baby so that the uterine contractions & placental separation is not left to the natural uncertain forces of labor
• Controlled cord traction on perception of a strong uterine contraction with out waiting for the actual signs of placental separation
• Uterine massage to maintain the contraction
Benefits of AMTSL
• Uterine atony accounts for 70-90% of all PPH cases
• AMTSL reduces: Incidence of PPH by 60%Quantity of blood loss—thereby decreasing incidence &
severity of anemiaEmergencies & related cost, transportThe use of blood transfusion
PPHaemorrhage - causes
4Ts: Tone: uterine atony, Tissue: retained placenta or retained products, Tears: cervical or perineal, or ruptured uterus), Thrombin: coagulation disorder
Coagulation disorders may also be associated with haemorrhage
Symptoms & signs
Associated findings
Probable diagnosis
Immediate PPH Uterus soft & not contracted
Bleeding may be continuous or Intermittent, Shock
Atonic uterus
Immediate PPHUterus contracted
Bleeding is bright red and continuous (Complete placenta expelled)
Traumatic PPH- tears in the cervix or vagina
Placenta not delivered within 30 min of delivery
PPH may or may not be present
Retained placenta
Diagnosing the cause of PPH
Portion of placenta missing or membranes torn
Uterus relaxed PPH
Retained placental fragments
Uterine fundus not felt on abdominal palpation
Inverted uterus apparent at vulvaImmediate PPH
Inverted uterus
Shock due to Haemorrhage
Shock is a life threatening condition that requires immediate, intensive treatment
The presence of shock mean that there is an inadequate perfusion of organs & cells with oxygenated blood. There is some form of cardiovascular compromise
Signs Present?
When signs are there they are SIGNIFICANT Have a high suspicion and ACT QUICKLY!
Shock due to Haemorrhage –Signs
Pale Confused Increased HR Reduced BP (late sign) Reduced urine output Obvious or hidden bleeding
Signs of shock Brain -unconscious, anxious, agitated and confused, drowsySkin - sweaty or cold and clammyBreathing - rapidConjunctivae - palePulse - weak and fast >100/minute (sometimes “bounding pulse”)BP - low systolic < 90 mmHg (late sign)Kidney - poor urine output
Haemorrhage - management
Follow the protocol
ABCs
C - replace the volume - stop the bleeding
Haemorrhage
ABCs Circulation
IV access by 2 large bore cannulae
Send off blood samples Give iv fluids
16G – GREY: 1 litre in 5 mins
18G – GREEN: 1 litre in 10 mins
20G – PINK: 1 litre in 15 mins
22G – BLUE: litre in 30 mins
Shock- immediate actionCirculation
Get iv access and send blood samples
If pulse>100 / minute or BP< 90 mm Hg or heavy vaginal bleeding Give 1 l iv fluid over 20 minutes Give further 1 l over 30 minutes Review the situation and repeat if necessary
Beware – if underlying anaemia or severe pre-eclampsia
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! (So REFER to FRU early)
• Replace as quickly as you can if patient shocked
• Be guided by the patients signs and response (e.g. Pulse rate, level of consciousness)
Be aware of blood lost!Signs Blood lost Action
Mild increase in pulse-
700 mls Give iv fluids
Increase in pulse and respiratory rate
1500 mls Give iv fluids
Fall in BP 2000 mls Give fluids and blood
Cold, drowsy, very high pulse, very low BP
2500 mls Large transfusion required
Shock- immediate actionAscertain the cause of haemorrhageCover her and keep her warmKeep a careful record of input and output and drugs
given
If at a lower level facility, Prompt Referral to FRU after resuscutation
Diagnosing the cause of PPH
The most important step in making a diagnosis of the cause of PPH is to keep a hand on the lower abdomen of the woman and feel for the uterine tone
PPH – How to manage
Stepwise approach in case of uterine atony
Uterine atony
Empty bladder Give Oxytocics Check for
placenta completeness genital tract injury
Rub uterus Bimanual compression Aortic compression Uterine tamponade
Management (Contd.)
Massage uterus to expel clots and feel to see that it is contracted—recheck intermittently
Give oxytocin 10 units IM Give iv fluids Oxygen @6-8 L/ minute by mask
Oxytocic DrugsOxytocin Ergometrine/ 15-methyl
prostaglandin F2
Dose and Route IV: Infuse 20 units in 1 L at 60 drop/min.IM: 10 units
IM 0.2 mg IM: 0.25 mg
Continuing Dose
IV: Infuse 20 units in 1 L at 40 drop/min.
Repeat 0.2 mg IM after 15 min. If required, give 0.2 mg IM every 4 hours
IM: 0.25 mg every 15 min.
Maximum Dose Not more than 3 L of IV fluids
5 doses 8 doses
Precautions/Contraindications
Do not give as IV bolus
Pre-eclampsia, hypertension, heart disease
Asthma
Bimanual Compression of Uterus
Wearing sterile gloves, insert hand into vagina; form fist
Place fist into anterior fornix and apply pressure against anterior wall of uterus
Bimanual Compression of Uterus (contd.)
With other hand, press deeply into abdomen behind uterus, applying pressure against
posterior wall of uterus Maintain compression until bleeding is controlled and uterus contracts
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
Compression of Abdominal Aorta (Contd.)
• Maintain compression until bleeding is controlled
Uterine Tamponade (1)
Uterine Tamponade (2)
Up to 500mls or until the uterus is contracted
RETAINED PLACENTA: MRP•IV oxytocin, oxygen, Empty bladder, CCT•If CCT not successful, on PV it can be felt in cervix, grasp & remove.•If still cannot be removed, & Cx is dilated,MRP should be attempted give plasma expanders, additionally•If placenta is retained & no bleeding refer to FRU.
Traumatic PPH Episiotomy Perineal tears and lacerations Vaginal tears Cervical tears Uterine rupture Broad ligament hematoma Para-vaginal & Vulval hematoma
Follow-up care in atonic PPH
• Monitor the vital signs( pulse, BP, RR) • every 10 min. for the first 30 mins,
• every 15 mins. for the next 30 mins. & then• every 30mins. for the next 3-6 hours or until stable.
• Palpate the uterine fundus to ensure that the uterus remains contracted.
• Continue oxytocin infusion• Monitor the urinary output - should be more than 30 ml/
hour
Not a common condition Pulling on the umbilical cord in the
absence of a uterine contraction in an effort to deliver the placenta can cause inversion of uterus
Acute Uterine Inversion
Manual replacement of uterus Give the woman IV sedation with Inj.
Pentazocine (Fortwin) 30mg, and Inj. Phenergan 25 mg.
Ensure aseptic precautions Insert a hand into the vagina. Feel for the
cervical rim. Reposit the uterus back, starting with the part
that comes out last (the fundus comes out first and the portion of the uterus just above the cervix comes out last)
Uterine Inversion
‘O’ Sullivan’s hydrostatic pressure method can be attempted (?) if service provider is experienced
Do not remove the placenta, if attached to uterus, before vaginal replacement of the uterus as it can lead to severe hemorrhage
Prevention
Do not pull on the cord in the absence of a uterine contraction.
Always apply "counter-traction" with the other hand while carrying out controlled cord traction.
Do not apply fundal pressure to deliver the baby or the placenta.
DELAYED PPH Management• Give Inj. Oxytocin 10 IU I/M stat• Start IV infusion of 20 IU Oxytocin in 500 ml of Ringer Lactate / Normal saline at rate of 40-60 drops / min• Suspect infection if fever and / or foul smelling vaginal discharge• Give first dose of antibiotics Cap. Ampicillin 1 gm oral Tab. Metronidazole 400 mg oral Inj. Gentamycin 80 mg IM stat• Refer to FRU
KEYPOINTS
• Prevent PPH Practice AMTSL• Diagnose & treat PPH promptly if it occurs• Quick assessment of mother’s condition &
Tx of shock.• Identify the cause of PPH and manage
accordingly.• Timely referral to FRU where blood is
available (after immediate management)
