Management of Hemoperitoneum Post-LSCS

Immediate Stabilization and Assessment

The American College of Radiology recommends immediate hemodynamic stabilization, urgent imaging with CT or ultrasound to identify the bleeding source, and surgical re-exploration in most cases, as conservative management is rarely successful for significant intra-abdominal hemorrhage 1, 2
Assess hemodynamic stability immediately by checking vital signs, signs of hypovolemia, and severity of active bleeding 2
Establish large-bore IV access and initiate aggressive fluid resuscitation with crystalloids initially, followed by blood products as needed 2
Obtain baseline laboratory studies urgently, including complete blood count, coagulation profile, and type and crossmatch for at least 4-6 units of packed red blood cells 2
Maintain normothermia (>36°C) as hypothermia severely impairs clotting factor function and worsens coagulopathy 2
Do not delay intervention while waiting for laboratory results if the patient is hemodynamically unstable—treat based on clinical presentation 2

CT abdomen and pelvis with IV contrast is the gold standard for hemodynamically stable patients to determine the presence of active hemorrhage, localize bleeding, and identify the source 1
Look for specific CT findings, such as active contrast extravasation, hematoma location, uterine rupture signs, or uterine dehiscence 1
Small hematomas (<4 cm) may not be clinically significant and can be managed conservatively, but larger collections require intervention 1

Surgical re-exploration is the definitive treatment for significant hemoperitoneum post-LSCS, as conservative management rarely controls substantial intra-abdominal bleeding 2
Indications for immediate surgical intervention include hemodynamic instability, active ongoing hemorrhage, large or expanding hematomas, signs of uterine rupture, and clinical deterioration 1, 2

Transfuse blood products in 1:1:1 ratio (packed red blood cells: fresh frozen plasma: platelets) if massive hemorrhage occurs (>1500 mL blood loss or ongoing bleeding) 2
Administer tranexamic acid (1 gram IV over 10 minutes, then 1 gram over 8 hours) within 3 hours of delivery to reduce bleeding risk 2
Correct coagulopathy aggressively, targeting fibrinogen >200 mg/dL with cryoprecipitate, platelets >50,000/mm³, INR <1.5 2, 3

Administer uterotonics aggressively, even though the primary issue is surgical bleeding, as uterine atony may be a contributing factor 2
Oxytocin infusion: 10-40 units in 1000 mL crystalloid at 125-200 mL/hour 2
Methylergonovine 0.2 mg IM (avoid if hypertensive) 2
Carboprost 250 mcg IM every 15-90 minutes (maximum 8 doses; avoid if asthmatic) 2
Misoprostol 800-1000 mcg rectally 2

Uterine artery embolization may be considered for hemodynamically stable patients with persistent bleeding after initial surgical control, particularly if a vascular source is identified 1, 2
CTA (CT angiography) should be performed before embolization to identify feeding vessels and plan the procedure 1

Uterine rupture requires immediate laparotomy with uterine repair or hysterectomy depending on extent of injury 1
Coagulopathy-related bleeding should be considered if diffuse oozing without clear surgical source, and corrected aggressively 2, 3

Intensive care unit monitoring for at least 24-48 hours with continuous hemodynamic monitoring 2, 4
Serial hemoglobin/hematocrit checks every 4-6 hours initially to detect rebleeding 2
Maintain low threshold for re-exploration if clinical deterioration, falling hemoglobin, or increasing drain output occurs 4
Initiate pharmacologic thromboprophylaxis with low molecular weight heparin once hemostasis is secured (typically 12-24 hours post-surgery) 2

Never delay surgical intervention in hemodynamically unstable patients while pursuing imaging or conservative measures 2
Avoid blind digital examination before imaging excludes vascular abnormalities or placental complications 2, 5
Recognize that small hematomas on initial imaging can rapidly expand—maintain high clinical suspicion and repeat imaging if clinical deterioration occurs 1
