Management of Bleeding 3 Weeks After Miscarriage

Initial Assessment

Evaluate vital signs, mental status, and clinical presentation to determine the severity of bleeding 1
Obtain baseline laboratory studies including complete blood count, prothrombin time (PT), activated partial thromboplastin time (aPTT), and fibrinogen levels 2
Do not rely solely on single hemoglobin/hematocrit measurements as isolated markers for bleeding severity 2, 3
Measure serum lactate and base deficit to estimate and monitor the extent of bleeding and shock in hemodynamically unstable patients 2, 3

Perform transvaginal ultrasound as the standard test to assess for retained products of conception, arteriovenous malformation, or other complications 1
Consider focused abdominal sonography (FAST) for detection of free fluid if significant bleeding is present 3
For patients with hemodynamic stability but ongoing bleeding, consider additional imaging such as CT if indicated 3

Secure large-bore intravenous access for fluid resuscitation 3
Initially use crystalloids for fluid resuscitation 3
Target a systolic blood pressure of 80-100 mmHg until major bleeding has been controlled 3
For massive hemorrhage, administer warmed blood products as needed 3
Consider tranexamic acid 10-15 mg/kg followed by infusion of 1-5 mg/kg/h in patients with significant bleeding 3, 4

Patients with heavy bleeding, hemodynamic instability, or requiring surgical intervention should be admitted 1

Avoid delays between diagnosis and intervention for patients requiring urgent bleeding control 2
Do not rely solely on blood pressure as an indicator of blood loss, as some patients compensate well despite significant hemorrhage 3, 4
Consider the possibility of ectopic pregnancy, especially if the initial miscarriage was not confirmed by ultrasound 1
