3ANTEPARTUM HAEMORRHAGE
- Bleeding from genital tract gt 24 weeks of
gestation Causes before and after 24 weeks are
the same. - Massive obstetric haemorrhage - blood loss gt1
litre from genital tract - Significant cause of MMR in India, 3rd common.
- Incidence 5 of all haemorrhage.
- gt50 due to placenta previa abruption
- The rest is due to unclassified causes.
4CAUSES OF APH
- Placenta - 2/3 due to previa or abruption
- Uterus- Before or after onset of labour
- Scarred uterus- Classical Caesarean section /
Myomectomy/ Inverted T shaped incision. - Unscarred uterus- Grand multipara when oxytocin
is used for augmentation /Obstructed labour /
Rotational forceps deliveries.
5CAUSES OF APH
- Cervix - cervical erosion or polyps ,due to
increased vascularity (after sex or infection) - CA cervix / after cervical conisation or LLETZ.
- Vagina - uncommon , secondary to candida or HPV.
- Vulva due to varices.
- Consider pre existing clotting disorders VWF
deficiency, decreased factor VIII activity along
with defect in platelets
6ANTEPARTUM HAEMORRHAGE (contd)
- Recurrence depends on the cause.
- In Previa there is 8-10 fold increase in risk.,
LSCS increases the risk further and it is
relevant as CS rates are on the rise. - In abruption the risk is 10 and in gt50 cases
recurrent episode is severe than the original
one.
7ANTEPARTUM HAEMORRHAGE (contd)
- Management
- Management is essentially the same whatever the
cause of APH. - Each unit should have a agreed protocol and it
should be readily available. - All staff should be familiar of this protocol and
regular practice of firedrills held.
8SIGNS AND SYMPTOMS - HAEMORRHAGE
- Depends on the degree of blood loss.
- Mild shock- lt20 of blood volume - decreased
perfusion to non vital organs and tissues like
skin, face, skeletal muscle and bone. - Moderate shock- 20-40 of blood volume- decreased
perfusion to vital organs like liver, GIT and
kidneys. (decreased BP, oliguria, mottling of
skin). - Severe shock- gt40 of blood volume- decreased
perfusion to heart and brain causing
restlessness, agitation, coma, ECG, EEG changes
causing possible cardiac arrest.
9MANAGEMENT - APH
- Resuscitation
-
- Best way to resuscitate the fetus is to
resuscitate the mother. -
- Conversely the delivery of fetus (whatever the
gestational age) may help to resuscitate the
mother removing the fetoplacental unit and
increasing the maternal venous return. -
10MANAGEMENT - APH
- General principles
- 1) Call for HELP
- Team of senior obstetricians , anaesthetists and
peadiatricians should be called for. -
- To reserve and arrange cross matched blood
-
- Operation theatre should be kept ready for
immediate delivery if fetus is viable. -
11MANAGEMENT - APH
- 2) ABC should be followed
- Airway to assess and maintain.
- High flow oxygen and reservoir
bag 15 l/min - Monitor SPO2 and RR.
-
- Breathing- Assess and protect airway
- Ventilate if adequate.
-
12MANAGEMENT - APH
- Circulation- External cardiac massage if required
- 15 degree lateral tilt no
supine position - To assess the volume of blood
loss - To check peripheral perfusion
- HR / BP/ output every half
hourly - Important always the blood loss is usually
underestimated. - 3 ) Replace the blood loss.
- Two large wide bore cannula (16G)
- Blood to be sent for CBC, coagulation screen,
Kleihauer test, urea and electrolytes. - Cross match 4-6 units of blood.
13MANAGEMENT APH (contd)
- Initial management up to 2L of NS followed by
synthetic colloid (Haemaccel). - To transfuse blood.
- O negative blood can be used in case emergency
(decreased risk of sensitization to antigen) - Otherwise group specific crossmatched blood to be
transfused. - Consider warming of fluids and infusion with
pressure bag.
14MANAGEMENT APH (contd)
- Fresh whole blood does not allow time for full
infection screen. - gt 48 hours, platelet and clotting factors
function is decreased. - Stored whole blood is rarely available.
- PRBCs each pint contains 220ml of RBCs 80ml
of SAGM solution (Saline, adenine,glucose,
mannitol) it has shelf life of 35 days. - Group specific blood following antibody screen -
lt0.1 risk of haemolysis, risk increases to 1 if
used without
antibody screening.
15MANAGEMENT APH (contd)
- If planning for caesarean section senior
obstetrician / anesthetist. - If fetus is dead induction of labour. In case
of delay in delivery then consider Caesarean
section as there is risk of DIC. - PPH should be expected and need for caesarean
hysterectomy should be discussed. - Aggressively treat coagulopathies.
16PLACENTA PREVIA
- Grading of placenta previa is important.
- Age gt35 years, parity, previous LSCS, repeat
curettage for abortions increases risk by 2
fold - Multiple pregnancies, cocaine use - increases
risk by 2-4 fold - Smoking- increases risk by 3-6 fold
- Diagnosis routine USG
- TVS gold standard, no increased risk of
bleeding.
17PLACENTA PREVIA
- Complications
- Fetal major malformations
- Increased risk of RDS
- Fetal prematurity
- Anaemia
18PLACENTA PREVIA
- Maternal related to bleeding
- 30 no bleeding
- 10 fold increased risk of
antepartum bleeding. - 2.5 fold increased risk of
intrapartum bleeding. - 1.9 fold increased risk of
postpartum bleeding. - Increased risk of abruption
13.8 likelihood ratio. - Peripartum hysterectomy x 33 fold.
- PPH is increased due to poor contractility of
placental bed. - Air embolism from low pressure venous sinuses.
19MANAGEMENT PLACENTA PREVIA
- Caesarean section except grade I
- Aggressive approach to blood transfusion.
- Tocolysis if threatened preterm labour to
prolong the pregnancy ?. - Elective cervical circlage only clinical
studies. - Risk of fetal malpresentation transverse lie or
oblique lie- caesarean section - Caesarean section technique- posterior or
anterior, transplacental approach with rupture of
the amniotic sac. - Should be done under GA, under regional
anaesthesia hypotension
20ANTEPARTUM HAEMORRHAGE (contd)
- Adherent placenta
- Uterine artery ligation / embolisation or
systemic methotrexate. - Vasa previa
- Fetoplacental vessels over the internal os rather
than the placenta. - Associated with succenturiate lobe, multilobed
composition.
21ABRUPTIO PLACENTA
- Incidence 15
- revealed 2/3
- concealed 1/3
- Classification
- I haemorrhage with pain and uterine
irritability, no maternal or fetal compromise. - II- No maternal compromise, but fetal
distress is recognised. - III- Uterine tetany, maternal compromise and
fetal demise. - It is clinical diagnosis.
- USG- sensitivity for abruption poor 24.
22ABRUPTIO PLACENTA
- Risk factors
- Cigarette smoking.
- Hypertension disorders.
- Direct abdominal trauma- RTA, domestic violence,
gt1 incidence risk of abruption increased by 4
fold - Acquired and inherited thrombophilias including
APLA syndrome. - Sudden uterine decompression polyhydramnios
with rupture of membranes. - Obstetric procedure- External cephalic version.
23ABRUPTIO PLACENTA (contd)
- Management
- Depends on
- 1) Grade of presentation
- 2) Fetal gestational age.
- 3) Concomitant pathology.
- Conservative treatment in grade 0 only.
(retroplacental clot)
24POST PARTUM HAEMORRAHAGE
- Accounts for ¼ of all maternal deaths worldwide,
where as 1/3rd of all maternal deaths in
developing countries, including INDIA. - Severe obstetric morbidity may be a more
sensitive measure of pregnancy outcome than
mortality alone as its highest for haemorrhage. - Definition
- Estimated blood loss gt 500ml following vaginal
delivery / gt 1litre following caesarean section.
25POST PARTUM HAEMORRAHAGE (contd)
- Major haemorrhage loss gt 2.5L or requiring gt
5units transfusion or treatment for coagulopathy.
(FFP/ cryo/ platelets) - Depends on her blood volume and underlying health
factors , Not only on the amount but rate of
blood loss. - Primary - lt24 hours
- Secondary - gt24 hours.
26POST PARTUM HAEMORRAHAGE (contd)
- Etiology
- Tone
- Tissue
- Trauma
- Thrombus
27POST PARTUM HAEMORRAHAGE (contd)
- Common risk factors
- Overdistended uterus

- Increased maternal age Assisted reproductive
techniques , multiple pregnancies, increased
LSCS, instrumental deliveries, complex medical
disorder, previa. - Chorioamnionitis, prolonged PROM
- Fibroid, previous LSCS
- APH, induction of labour, preeclampsia
- Prolonged labour, instrumental delivery
- Previous PPH
- Without risk factors still PPH can be there in
60 of cases.
28POST PARTUM HAEMORRAHAGE (contd)
- Pathophysiology
- Living ligatures.
- Active management of III stage of labour enhances
the process. - Prevention
- Anemia and other health issues are treated
antenatally
29POST PARTUM HAEMORRAHAGE (contd)
- Appropriate management of labour and delivery as
follows - Uterotonic agents.
- Controlled cord traction.
- Uterine massage after placental delivery.
- Early cord clamping vs. delayed cord clamping
less fetal anemia, IVH late onset sepsis.
30POST PARTUM HAEMORRAHAGE (contd)
- Drugs
- Oxytocin 5 units IV or 10 units IM, bolus
- Ergometrine maleate 500ug IM
- Misoprostal PGE1 analogue- oral or sublingual or
rectal routes. (low resource setting) - Carbetocin long acting oxytocin agonist.
- PGF2 alpha 250mcg IM stat
31POST PARTUM HAEMORRHAGE (ctd)
-
- A recent Cocharane review neither im
- prostaglandins/ misoprostal preferable to
- conventional injectable uterotonics in low risk
- women.
32POST PARTUM HAEMORRAHAGE (contd)
- The WHO held technical consultation on the
prevention of PPH in 2006 recommended that - Active management of III stage of labour should
include uterotonic soon after birth of baby,
delayed cord clamping and delivery of placenta by
controlled cord traction. - Risk of uterine inversion, therefore offered by
skilled attendants. - oxytocin is offered in preference to misoprostol.
33TREATMENT - PPH
- General
- H- ask for help
- A- assess (vital, blood loss) and resuscitate
golden hour the time at which resuscitation
is initiated for best chance for survival. - E- Establish the etiology, 4Ts
- Ecbolics (bolus syntocinon,
ergometrine) - M-massage uterus
- O- Oxytocin infusion, Prostaglandins
(IV/rectal/im/ intramyometrial)
34TREATMENT - PPH
- Specific surgical management
- S Shift to OT, bimanual compression.
- T- tissue, trauma excluded by exploration under
GA proceed to tamponade balloon / uterine
packing. - A- Apply compression sutures.
- S- Systemic pelvic devascularisation (uterine,
ovarian, quadruple, internal iliac). - I - Interventional radiology uterine artery
embolisation - S - Subtotal or total abdominal hysterectomy.
35SHOCK IN OBSTETRIC PATIENTS
- Shock- critical condition and life threatening
medical emergency - Results from acute generalized inadequate
perfusion of the tissues below that needed to
deliver oxygen and nutrients for normal cell
function. - Commonly due to haemorrhage or sepsis.
- Substandard care is still an issue in the
management of shocked patient. - Prompt recognition and management can improve
maternal and fetal outcome in shock.
36SHOCK IN OBSTETRIC PATIENTS (contd)
- Etiology -
- Hypovolemia due to haemorrhage, dehydration due
to hyperemesis, DKA, burns. - Sepsis endotoxemia.
- Cardiogenic- massive PEM, cardiomyopathies,
obstructive structural lesions, dysrrhythmias,
regurgitant lesions. - Distributive shock (Neurogenic )
- anaphylaxis
- regional anaesthesia
- spinal injury.
37PATHOPHYSIOLOGY- SHOCK
- Untreated shock progresses through 3 stages
- Compensated - no fluid required if underlying
cause is treated. - Decompensated decreased perfusion to heart,
brain, kidneys. - Irreversible- Acute tubular necrosis, severe
acidosis with decreased myocardial contractility.
38SHOCK IN OBSTETRIC PATIENTS (contd)
- Diagnosis
- No laboratory tests is required.
- A high index of suspicion and physical signs of
inadequate perfusion are the basis of initiating
treatment. - It does not depend on the underlying cause.
39INITIAL MANAGEMENT - SHOCK
- Successful management requires team work.
- Established protocols and practice fire drills.
- Management of the underlying cause is secondary.
- Delivery may be considered as a part of
resuscitating the mother. - ABC situation along with control of haemorrhage.
- Vasoactive drugs (inotropes and vasopressors) if
cause of shock is due to myocardial depression.
40SPECIFIC PROBLEMS
- Haemorrhage and hypovolemia
- Due to APH or PPH.
- Haemodynamic considerations in pregnancy
increased cardiac output by 50 and blood volume
by 45 reaching a peak at 28-34 weeks of
gestation. - Correspondingly greater fluid losses (gt30 of
circulating volume) can occur before anything
other than maternal tachycardia is seen. - If Antenatal decreased fetal perfusion causes
abnormal FHR pattern.
41MANAGEMENT OF SHOCK (contd) Developments in
management of massive haemorrhage
- Cell salvage
- Blood from operative site -? heparin tubing ,
filtered -? washing and centrifugation - Widely used in cardiac, vascular, trauma and
other major situations. Obstetric theatres are
slow to introduce this technique because of the
risk of amniotic fluid embolism and rhesus iso
immunization. - Autologous transfusion
- Pre-donation Isovolemic hemodilution
- economically viable
- only red cells with HCT 55-80
- Will not correct coagulopathy
42MANAGEMENT OF SHOCK (contd)
- Recombinant factor VIIA key initiator in
haemostasis - Increases thrombin, factor V, VIII and
platelet at the site of injury - Activates factor IX and generates more factor
Xa. - Pelvic arterial embolisation.
- Balloon tamponade.
43MANAGEMENT OF SHOCK (contd)
- SEPTIC SHOCK
- Uncommon in pregnancy in developed countries,
still the second common cause of MMR in India. - In obstetric patients mortality due to sepsis is
3, upto 50 due to non obstetric cases. - Strict aseptic precautions should be followed for
any obstetric procedures especially in rural
India.
44MANAGEMENT OF SHOCK (contd)Spectrum of related
pathologies
- Systemic inflammatory response (SIRS) presence
of two or more of following - (i) temperature lt36 or gt38 degree F.

neutrophils. - Sepsis SIRS evidence of infection (suspected
or known)
45MANAGEMENT OF SHOCK (contd)Spectrum of related
pathologies
- Septic shock at least 2 criteria to be met
- evidence of infection through a positive blood
C/S - Refractory hypotension despite adequate fluid
replacement needs inotropes and vasopressors. - Sepsis with multiorgan dysfunction

- Blood C/S and C/S from other sites and IV
antibiotics - Removal of infected tissues
- Goal directed therapy.
49MANAGEMENT OF SHOCK (contd)
- Advances in sepsis management
- Early goal directed therapy involves modifying
the components of treatment to achieve specific
end points. - MAP gt/ 65mmHg
- Urine output gt0.5 ml/kg/hr
- CVP 8-12 mmHg
- Normal mixed venous arterial saturation in ABG.
- Insulin treatment, APC not contraindicated in
pregnancy, steroids not known.
50MANAGEMENT OF SHOCK (contd)
- III Cardiogenic shock
- Pre existing cardiac disease makes the parturient
at risk. - Anaphylaxis
- Due to drugs, food, latex and insect stings.
- Upto 5 of cases causative agent cannot be
identified. - Clinical features cutaneous / CVS/
respiratory/ CNS/ GI
51MANAGEMENT OF SHOCK (contd)
- Basic shock management , ABC and circulatory
management. - Special aspects
- Immediate Stop administration of
suspected agent and call
for help, Airway early intubation. - Supine or
trendelenburg position. - Give epinephrine IM
every 5-15min, titrated to pulse or BP
until improvement occurs. - In severe
hypotension IV epinephrine. - IV expansion and
crystalloid. - If cardiac arrest CPR and ALS protocols.
52MANAGEMENT OF SHOCK (contd)
- Secondary
- If hypotension persists IV epinephrine infusion
alternative pressor agents / Atropine - if
bradycardia - If bronchospasm salbutomol nebulisation,
inhaled ipratropium if on B blockers, - Antihistamines.
- Steroids IV but the effect is not immediate.
- All patients with severe anaphylaxis ? critical
care. - Investigations immediate - Serum tryptase may
be elevated due to mast cell degranulation. - Late- refer to immunologist for investigations.
53MANAGEMENT OF SHOCK (contd)
- AF embolus
- Rare but devastating.
- Characterized by abrupt CV collapse and
Coagulopathy. - During labour or in the immediate post partum
period. - Pathophysiology- mechanism of AFE is poorly
understood. - The term anaphylactoid syndrome should be
considered.
54MANAGEMENT OF SHOCK (contd)
- Clinical features
- Late stage of labour- acute dyspnoea,
hypotension, seizures, and cardiac arrest may
quickly follow. Most of them die with in one hour
of arrest. - Left ventricular failure and massive DIC
associated hemorrhage occurs in survivors of
initial event.
55MANAGEMENT OF SHOCK (contd)
- Management
- Basic CPR followed by ICU admission.
- Circulatory support
- Perform LSCS in arrested mothers, who are
unresponsive to resuscitation with in 5 minutes
(Perimortem caesarean section) to aid CPR.
56MANAGEMENT OF SHOCK (contd)
- IV DISTRIBUTIVE SHOCK
- No loss of intravascular volume or cardiac
function. - The primary defect is massive vasodilatation
leading to hypovolemia, reduces perfusion
pressure and therefore poor flow to tissues. - A) Spinal injuries reduced sympathetic tone-
profound vasodilatation. - Special aspects Fluids / vasopressor/ atropine
for unopposed vagal activity.
57MANAGEMENT OF SHOCK (contd)
- B)Anaesthesia (i)shock due to GA- anaphylaxis.
- (ii)Regional blocks- epidural / spinal.
- Factors include- use of standard non obstetric
dose , excessive spread of intrathecal injection
of appropriate dose, accidental intrathecal
injection of the drug due to unrecognized dural
puncture or migration of epidural catheter. - Hypotension can be increased by incorrect
positioning of the patient , eg absence of
lateral tilt causing aorto caval compression.
58MANAGEMENT OF SHOCK (contd)
- Clinical features
- All regional anaesthesia technique produce a
level of sympathetic blockade (vasodilatation),
motor blockade (weakness). - Signs of high block
- Hypotension- feeling unwell / nausea.
- Bradycardia- (T1-T4)
- Upper limb neurological signs C5-T1

- - Special aspect
- Support CVS- vasopressor drugs, inotropes
to maintain blood pressure. - Sedative agents can reduce the risk of
awareness. - (iii) Local anaesthetic toxicity (due to
increased plasma concentration) - Accidental IV injection, rapid absorption,
absolute overdose - It can cause seizures, dysrrhythmia, hypotension.
60MANAGEMENT OF SHOCK (contd)
- Treatment
- Basic shock management.
- Seizure management.
- Deliver the baby
- Sedation.
61SEVERE PREECLAMPSIA
- Stepwise system of management of Gestational
hypertension - Screening in pregnancy.
- Positive family history
- Past h/o or preexisting hypertension
- Signs and symptoms of impending eclampsia-
headache / visual disturbances, abdominal pain,
vomiting.
62SEVERE PREECLAMPSIA (contd)
- Prior to delivery
- Regularly update management protocols.
- Stabilise with antihypertensive drugs if
required. - Prophylactic steroids if lt34 weeks.
- Consider the need for Magnesium sulphate.
- Continue monitoring for signs of disease
progression and fetal monitoring. - Delivery of baby in the best way / best day /
best place.
63SEVERE PREECLAMPSIA (contd)
- Antihypertensive regimen
- Labetolol, methyldopa, hydralazine, nifedipine
are effective. - Anticonvulsant im or iv in case of eclampsia-
magnesium sulphate. - To monitor respiratory rate, knee jerk, urine
output during anticonvulsant therapy. - For Magnesium sulphate toxicity Inj calcium

- PPH
- Status eclampticus.
66 SEVERE PREECLAMPSIA
- Risks of fetus in PIH
- Abruption
- IUGR
- Iatrogenic prematurity.
67SEVERE PREECLAMPSIA (contd)
- CVP misleading in PIH , due to pulmonary edema.
- Not gt5cm H2O or 7cm of H2O.
- Oxygen saturation- pulse oximetry
- Fluid dry side 80ml/hr
- Overload occurs gt16hours when there is failure of
post partum diuresis - If pulmonary edema- 40mg frusemide followed by
20g mannitol.
68MANAGEMENT PROTOCOL
- Maternal management
- Keep blood crossmatched
- Control of blood pressure by antihypertensives
- Average 4 readings for BP monitoring
- Labs- uric acid, platelets, and LFT for enzymes
twice weekly. - Proteinuria /- quantification.
69MANAGEMENT PROTOCOL
- Fetal management (main risks- placental
insufficiency and prematurity) - Prophylactic steroids if gestational age lt34
weeks - Initial USG for estimated fetal weight (serial
growth is of no use every 2 weeks because maximum
prolongation of pregnancy may be so much) - Daily NST (change in the trace is important)
- Doppler USG of umbilical artery and AFI twice
weekly.
70ECLAMPSIA (contd)
- Indications for delivery in severe PIH
- Eclampsia all cases
- Severe PIH at 34 weeks
- If lt34 weeks with PROM, IUGR, abruption.
- Maternal disease BPgt160/110, oliguria, severe
proteinuria gt75 g/dl, platelet lt1lakh, pulmonary
edema. - Fetal compromise (depends on NICU/ GA) abnormal
KCC, NST, BPP, REDF.
71MANAGEMENT PROTOCOL
- Care after delivery
- Continued closed monitoring of mother.
- Careful fluid balance and use of diuretics
(colloids better than crystalloids as they pass
quickly across the interstitial space). - Gradual decrease of antihypertensives.
- Stop anticonvulsants gt48 hours if stable (if
prophylaxis 24 hours)
72SEVERE PREECLAMPSIA
- Follow up
- Long term to make sure that BP resolves.
- Discussion regarding what has gone on and the
significance for future. - If BP increases gt 6 weeks refer to physician
for other investigations.
73SEVERE PREECLAMPSIA (contd)
- Anaesthesia
- GA intubation and extubation increases BP.
- Epidural is better for labour analgesia as it
keeps the patient awake. - Adequate pain relief maintains normal BP.
- No need to cut short the II stage of labour if
adequate pushing efforts are present. - Post delivery inj methergine is contraindicated,
inj syntocinon/ prostaglandin can be given.
74ECLAMPSIA
- The progression of preeclampsia to eclampsia is
1/200 - Prophylactic Magsulph decreases it. - (MAGPIE TRIAL)
75ECLAMPSIA (contd)
- Mild treatment
- Initial hospitalisation 1) 4th hourly Blood
pressure - 2) baseline
BUN, Sr creatinine, platelets, uric acid,
dopplers, BPP twice a week. - DFMC
- Next visit OPD weight, BP, urine albumin, NST ?
if abnormal ? admit - Alphamethyl dopa, low dose aspirin, high dose
calcium - Encouraged till term 37-38 weeks if everything is
normal.
76TRAUMA IN PREGNANCY
- Key to effective management of traumatic pregnant
lady is to resuscitate the mother aggressively
and then to deliver the baby ? decrease in
maternal morbidity but allows the best chance of
fetal survival. - Principles of resuscitation are the same only
anatomical and physiological changes in
pregnancy, requires to modify certain steps in
resuscitation.
77TRAUMA IN PREGNANCY (contd)
- Team of trauma care, obstetricians,
peadiatricians, general surgeons should be
involved in. - Note the mechanism of injury
- deceleration injury
- direct impact (motor vehicle)
- penetrating injury (stab wound/ bullet or
projectile) - domestic violence
- To perform primary survey, ABC care, reevaluate
simultaneously .
78TRAUMA IN PREGNANCY (contd)
- Assess fetal well being and viability, decide for
delivery depends on gestational age- Perimortem
caesarean section with in 5 minutes of
unsuccessful CPR. - Assess and treat the wound in the abdomen.
- The pregnant uterus is resilient organ and it can
tolerate the severe pressure without rupturing.
79TRAUMA IN PREGNANCY (contd)
- Rupture of uterus may follow blunt trauma in
association with seat belts, although they reduce
overall mortality. - The fetus and the placenta are vulnerable despite
the buffering effect of amniotic fluid. The
placenta is inelastic unlike the uterus and
therefore liable to shearing. There is high
chance of fetomaternal haemorrhage and risk of
abruption.
80TRAUMA IN PREGNANCY (contd)
- With regard to examination
- Detection of intraperitoneal haemorrhage is even
more difficult in pregnant women 800ml of blood
needs to be present. - Peritoneum has decreased sensitivity in
pregnancy. - The USG focused abdominal sonography in trauma
(FAST) may be useful. - The indications for diagnostic peritoneal lavage
are same as non pregnant.
81TRAUMA IN PREGNANCY (contd)Penetrating wounds
(Stab/ gunshot)
- Above uterine fundus extensive GI or vascular
damage. - Uterine injury at any stage of pregnancy.
- Meticulous examination of abdominal contents is
essential. - Uterus should be opened when
- If a bullet is entered the uterus and the fetus
is alive and considered viable, the fetus should
be delivered by caesarean section.
82TRAUMA IN PREGNANCY (contd)Penetrating wounds
(Stab/ gunshot)
- To assess for fetomaternal haemorrhage (Kleihauer
test) - To perform secondary survey and start definitive
treatments. - To transfer the patient, if appropriate to higher
centre. - Keep a record chart of vitals, document injuries,
findings and treatment.
83BURNS IN PREGNANT WOMEN
- ABC situation
- Consider early intubation if smoke inhalation or
gt70 burns according to rule of nine. - ABG, fluid replacement with crystalloids.
- Assess for other injuries.
- Pregnancy does not affect maternal outcome of
burns
84BURNS IN PREGNANT WOMEN
- Fetal prognosis relates to the extent of burns.
- Spontaneous abortions if gt33 burns, during II
trimester. - Fetal loss during III trimester can be expected
unless delivery occurs within 5-7 days. - Remove all clothes and keep warm.
- Need for eschcerotomies.
- To document and consider transfer.
85
