bleeding in later pregnancy and labour
Types of bleeding
SHOUT FOR HELP. Urgently mobilize all available personnel.
Make a rapid evaluation of the general condition of the woman including vital signs (pulse, blood pressure, respiration, temperature).
Do not do a vaginal examination at this stage.
Diagnosis of antepartum haemorrhage
Presenting Symptom and Other Symptoms and Signs Typically
Symptoms and Signs Sometimes Present
• Bleeding after 22 weeks gestation (may be retained in the uterus)
• Intermittent or constant abdominal pain
• Tense/tender uterus
• Decreased/absent fetal movements
• Fetal distress or absent fetal heart sounds
• Bleeding (intra-abdominal and/or vaginal)
• Severe abdominal pain (may decrease after rupture)
• Abdominal distension/ free fluid
• Abnormal uterine contour
• Tender abdomen
• Easily palpable fetal parts
• Absent fetal movements and fetal heart sounds
• Rapid maternal pulse
• Bleeding after 22 weeks gestation
• Bleeding may be precipitated by intercourse
• Relaxed uterus
• Fetal presentation not in pelvis/lower uterine pole feels empty
• Normal fetal condition
Abruptio placentae is the detachment of a normally located placenta from the uterus before the fetus is delivered.
- If the
cervix is fully dilated, deliver by vacuum extraction;
vaginal delivery is not imminent, deliver by caesarean section.
Note: In every case of abruptio placentae,
be prepared for postpartum haemorrhage.
fetal heart rate is normal or absent, rupture the membranes with an amniotic hook or a Kocher clamp:
contractions are poor, augment labour with oxytocin;
the cervix is unfavourable (firm, thick, closed), perform caesarean section.
fetal heart rate is abnormal (less than 100 or more than 180 beats per minute):
- Perform rapid vaginal delivery;
vaginal delivery is not possible, deliver by immediate caesarean section.
COAGULOPATHY (CLOTTING FAILURE)
Coagulopathy is both a cause and a result of massive obstetric haemorrhage. It can be triggered by abruptio placentae, fetal death in-utero, eclampsia, amniotic fluid embolism and
many other causes. The clinical picture ranges from major haemorrhage, with or without thrombotic complications, to a clinically stable state that can be detected only by laboratory
Note: In many cases of acute blood loss, the development of coagulopathy can be prevented if blood volume is restored promptly by infusion of IV fluids (normal saline or Ringer’s
Use blood products to help control haemorrhage:
- Give fresh whole blood, if available, to replace clotting factors and red cells;
fresh whole blood is not available, choose one of the following based on availability:
- fresh frozen plasma for replacement of clotting factors (15 mL/kg body weight);
- packed (or sedimented) red cells for red cell replacement;
- cryoprecipitate to replace fibrinogen;
- platelet concentrates (if bleeding continues and the platelet count is less than 20 000).
Bleeding from a ruptured uterus may occur vaginally unless the fetal head blocks the pelvis. Bleeding may also occur intra-abdominally. Rupture of the lower uterine segment into the
broad ligament, however, will not release blood into the abdominal cavity (Fig S-2).
Rupture of lower uterine segment into broad ligament will not release blood into the abdominal cavity
Restore blood volume by infusing IV fluids (normal saline or Ringer’s lactate) before surgery.
When stable, immediately perform
caesarean section and deliver baby and placenta.
uterus can be repaired with less operative risk than hysterectomy would entail and the
edges of the tear are not necrotic, repair the uterus. This involves less
time and blood loss than hysterectomy.
Because there is an increased risk of rupture with subsequent pregnancies, the option of permanent contraception needs to be
discussed with the woman after the emergency is over.
Placenta praevia is implantation of the placenta at or near the cervix (Fig S-3).
Implantation of the placenta at or near the cervix.
Warning: Do not perform a vaginal examination unless preparations have been made for immediate caesarean
section. A careful speculum examination may be performed to rule out
other causes of bleeding such as cervicitis, trauma, cervical polyps or cervical malignancy. The presence of these, however, does not rule out placenta praevia.
bleeding is heavy and continuous, arrange for caesarean delivery irrespective of fetal maturity;
bleeding is light or if it has stopped and the fetus is alive but
premature, consider expectant management until delivery or heavy bleeding occurs:
- Keep the woman in the hospital until delivery;
- Correct anaemia with ferrous sulfate or ferrous fumerate 60 mg by mouth daily for 6 months;
- Ensure that blood is available for transfusion, if required;
bleeding recurs, decide management after weighing benefits and risks for the woman and fetus of further expectant management versus delivery.
CONFIRMING THE DIAGNOSIS
reliable ultrasound examination can be performed, localize the placenta. If
placenta praevia is confirmed and the fetus is mature, plan delivery.
ultrasound is not available or the report is unreliable and the pregnancy is less than 37
weeks, manage as placenta praevia until 37 weeks.
ultrasound is not available or the report is unreliable and the pregnancy is 37 weeks or
more, examine under double set-up to exclude placenta praevia. The double set-up
prepares for either vaginal or caesarean delivery, as follows:
- IV lines are running and cross-matched blood is available;
- The woman is in the operating theatre with the surgical team present;
- A high-level disinfected vaginal speculum is used to see the cervix.
cervix is partly dilated and placental tissue is visible, confirm placenta praevia and
cervix is not dilated, cautiously palpate the vaginal fornices:
spongy tissue is felt, confirm placenta praevia and plan delivery;
- If a
firm fetal head is felt, rule out major placenta praevia and proceed to
deliver by induction.
soft tissue is felt within the cervix, confirm placenta praevia and plan delivery (below);
- If membranes and fetal parts are felt both centrally and marginally, rule out placenta praevia and
proceed to deliver by induction.
- the fetus is mature;
- the fetus is dead or has an anomaly not compatible with life (e.g. anencephaly);
- the woman’s life is at risk because of excessive blood loss.
Note: Women with placenta praevia are at high risk for postpartum haemorrhage and placenta accreta/increta, a common finding at the site of a previous caesarean scar.
- Under-run the bleeding sites with sutures;
- Infuse oxytocin 20 units in 1 L IV fluids (normal saline or Ringer’s lactate) at 60 drops per minute.
