Case 1: Postpartum Hemorrhage from Uterine Atony

Patient Demographics

  • Age: 29 years
  • Sex: Female
  • Occupation: Graphic designer

Chief Complaint

"The patient is bleeding heavily after delivery."

History of Present Illness

The patient is a G3P3 who just delivered a 4,200-gram infant vaginally after a prolonged second stage of labor (3 hours of pushing with epidural). Oxytocin was running during labor for augmentation. Within 10 minutes of placental delivery, the nurse notes heavy vaginal bleeding with clots. The uterus is palpated above the umbilicus and feels soft and "boggy."

Risk Factors Present

  • Prolonged labor with oxytocin augmentation
  • Macrosomic infant (uterine overdistension)
  • Multiparity (G3P3)
  • Prolonged second stage

Vital Signs (At Time of Recognition)

  • BP: 100/60 mmHg (baseline was 118/72)
  • HR: 110 bpm (baseline was 78)
  • RR: 20 breaths/min
  • SpO2: 98% on room air

Initial Assessment

Quantified Blood Loss:

  • Estimated blood loss at recognition: 800 mL (by calibrated collection drape and weighed pads)
  • Ongoing heavy flow

Four T's Assessment:

  • Tone: Uterus boggy, fundus above umbilicus - PRIMARY CAUSE
  • Trauma: Cervix and vagina examined - no lacerations identified
  • Tissue: Placenta appeared complete on inspection
  • Thrombin: No history of coagulopathy, recent labs normal

Diagnosis

Primary Postpartum Hemorrhage from Uterine Atony

  • Blood loss exceeding 1,000 mL (cumulative)
  • Maternal tachycardia indicating early hypovolemic response

Immediate Management

Step 1: Call for Help

  • Activated hemorrhage response team
  • Called for additional nurses, obstetrician, anesthesiologist

Step 2: Establish Access and Labs

  • Second large-bore IV placed (18-gauge)
  • Blood sent for type and crossmatch, CBC, coagulation studies

Step 3: Uterine Massage

  • Bimanual uterine compression initiated
  • Vigorous fundal massage performed

Step 4: Uterotonic Agents

  • Oxytocin: 40 units in 1L lactated Ringer's, infusing rapidly
  • Methylergonovine: 0.2 mg IM (no hypertension)
  • Carboprost (Hemabate): 0.25 mg IM (no asthma)
  • Misoprostol: 800 mcg rectally

Step 5: Tranexamic Acid

  • 1 gram IV given within 3 hours of delivery

Step 6: Continued Monitoring

  • Cumulative blood loss tracked
  • Vital signs every 5 minutes

Response to Treatment

After 15 minutes:

  • Uterus becoming firmer with massage and uterotonics
  • Bleeding slowing
  • Cumulative blood loss: 1,400 mL

Laboratory Results:

  • Hemoglobin: 9.2 g/dL (admission was 11.8)
  • Platelets: 165,000
  • Fibrinogen: 280 mg/dL (normal)
  • PT/INR: Normal

Decision:

  • Blood transfusion initiated (2 units packed red blood cells)
  • Conservative management successful - no need for Bakri balloon or surgery

Final Outcome

  • Total estimated blood loss: 1,500 mL
  • Received 2 units PRBCs
  • Hemoglobin post-transfusion: 9.8 g/dL
  • Uterus firm, bleeding controlled
  • Stable for transfer to postpartum unit

Postpartum Management

  • Continued oxytocin infusion for 4 hours
  • Serial hemoglobin checks
  • Iron supplementation
  • Early ambulation with assistance (DVT prophylaxis)
  • Counseling regarding increased PPH risk in future pregnancies
