Match each etiology of postpartum hemorrhage to its correct category in the "4 Ts" framework: Causes: 1. Uterine atony 2. Retained placental fragments 3. Cervical laceration 4. Disseminated intravascular coagulation (DIC)
Answer
Uterine atony - Tone, Retained placental fragments - Tissue, Cervical laceration - Trauma, Disseminated intravascular coagulation (DIC) - Thrombin
Explanation
The 4 Ts provide a structured differential: contraction problems, retained material, injury, and clotting abnormalities. This framework helps avoid focusing on atony alone when bleeding persists. **Key takeaway:** Systematically consider all four categories.\n\n**Glossary:** **DIC**: disseminated intravascular coagulation, a serious clotting disorder.
