Management of Obstetric Emergencies: A Complete Clinical Guide for Students

1. Postpartum Hemorrhage (PPH) – Excessive Bleeding After Delivery

Definition:

PPH is blood loss >500 mL (Vaginal Delivery) or >1000 mL (C-section).

Causes (4 T’s):

  • Tone (Atony – Most Common): Uterus fails to contract.
  • Tissue (Retained Placenta): Placental fragments remain.
  • Trauma (Tears, Uterine Rupture): Genital tract injury.
  • Thrombin (Coagulopathy): Clotting disorders (DIC, HELLP).

Management:

  • Uterine Massage → First-line.
  • IV Oxytocin 10 IU + Tranexamic Acid (TXA) 1g IV.
  • If Bleeding Persists:

  • Additional Uterotonics: Misoprostol, Ergometrine.
  • Bakri Balloon Tamponade (If uterine atony).
  • B-Lynch Suture / Uterine Artery Ligation (Surgical).
  • Hysterectomy (Last Resort).

Monitor for Shock (BP, HR, Urine Output).


2. Eclampsia – Seizures in Pregnancy

Definition:

Eclampsia is preeclampsia (HTN + Proteinuria) + Seizures.

Management:

Prevent Further Seizures:

  • Magnesium Sulfate (Loading 4g IV over 10 min, then 1g/hr IV).
    Control BP:
  • Labetalol IV or Hydralazine IV.
    Immediate Delivery of Baby (Once Stable).

Complications: Stroke, HELLP, Pulmonary Edema.


3. Cord Prolapse – Umbilical Cord Below Presenting Part

Definition:

Umbilical cord slips out before the baby, leading to fetal hypoxia.

Signs:

  • Fetal bradycardia (<110 bpm).
  • Palpable cord in vagina.

Management:

  • Immediate Knee-Chest or Trendelenburg Position.
  • Manually Elevate Presenting Part (Relieve Compression).
  • Emergency Cesarean Section.


4. Uterine Rupture – Complete Tearing of Uterus

Definition:

Uterus ruptures completely, leading to fetal distress & maternal hemorrhage.

Risk Factors:

  • Previous C-section scar.
  • Prolonged obstructed labor.

Signs:

  • Sudden severe abdominal pain.
  • Loss of fetal station.
  • Fetal distress (Bradycardia, Late Decelerations).

Management:

  • Immediate Laparotomy.
  • Uterine Repair or Hysterectomy (If Severe).
  • Blood Transfusion as Needed.


5. Amniotic Fluid Embolism (AFE) – Rare, Fatal Emergency

Definition:

Amniotic fluid enters maternal circulation, causing anaphylactic shock.

Signs:

  • Sudden Hypoxia (Dyspnea, Cyanosis).
  • Hypotension, DIC, Cardiac Arrest.

Management:

  • High-Flow Oxygen + Intubation.
  • Aggressive IV Fluids & Vasopressors.
  • Correct Coagulopathy (Fresh Frozen Plasma, Platelets).

High Mortality – Requires ICU Care.


6. Shoulder Dystocia – Fetal Shoulder Stuck Behind Pubic Bone

Definition:

After head delivers, shoulders fail to pass through pelvis.

Risk Factors:

  • Macrosomia (>4 kg).
  • Gestational Diabetes.
  • Post-term pregnancy.

Management (HELPERR Mnemonic):

  • H – Call for Help.
  • EEpisiotomy if needed.
  • LLegs in McRoberts Maneuver (Flex thighs onto abdomen).
  • PPressure (Suprapubic).
  • EEnter Vaginal Maneuvers (Rubin, Woods Screw).
  • RRemove Posterior Arm.
  • RRoll to All-Fours (Gaskin Maneuver).

If all fail → Zavanelli Maneuver (Push Head Back & Do C-section).

8. Key Takeaways

  • PPH is managed with Oxytocin, TXA, and surgical interventions if needed.
  • Eclampsia requires Magnesium Sulfate & immediate delivery.
  • Cord prolapse & uterine rupture need emergency C-section.
  • AFE is a critical condition with high mortality, needing ICU care.
  • Shoulder dystocia is managed with McRoberts Maneuver & Suprapubic Pressure.
