POSTPARTUM HEMORRHAGE (PPH)
PPH is primarily caused by the "4 T's":
🥚Tone (uterine atony)
🥚 Trauma
🥚Tissue, and
🥚Thrombin.
Uterine atony is the most common cause, responsible for roughly 70% of cases, where the uterus fails to contract after childbirth. Other major causes include lacerations, retained placental tissue, and blood clotting disorders.
MAIN CAUSES OF POSTPARTUM HEMORRHAGE (The 4 T's):
✅ Tone (Uterine Atony - ~70-80% of cases): The uterus fails to contract and compress bl@ vessels after the baby and placenta are delivered. Risk factors include a very long or very fast labor,, an enlarged uterus (due to multiple babies, large baby, or too much amniotic fluid), or infections like chorioamnionitis.
✅ Trauma (Lacerations/Rupture): Injuries to the ge***al tract, including the cervix, va**na, or uterus. This can occur during a Cesarean delivery, instrumental delivery (forceps/vacuum), or if a large baby causes significant tearing.
✅ Tissue (Retained Placenta/Clots): Pieces of the placenta or blood clots remain inside the uterus, preventing it from contracting properly.
This is common with placenta accreta (abnormal placental attachment).
✅ Thrombin (Coagulation Disorders): Blood fails to clot effectively, which can be due to pre-existing conditions or conditions developed during pregnancy, such as placenta abruption or severe preeclampsia (e.g., DIC - disseminated intravascular coagulation).
KEY RISK FACTORS:
🥚Prior history of PPH.
🥚Overdistended uterus: Multiple gestations,
🥚polyhydramnios (excess amniotic fluid), or
🥚fetal macrosomia (large baby).
🥚Induced or prolonged labor.
🥚Maternal age over 35.
Immediate management typically involves uterine massage, medication to induce contractions (like oxytocin), and sometimes surgery or bl@ transfusions.
