Jun 26, 2023 · • The 4 T's of postpartum hemmorrage refer to the causes, which include: tone (uterine atony), trauma (laceration), tissue (retained placenta), and thrombin (coagulopathies). • Future technology seeks to identify postpartum hemorrhage earlier with the help of wearable devices capable of monitoring a patient’s hemodynamic state.

The definition of early postpartum hemorrhage (PPH) is “Cumulative blood loss of ≥1000ml or bleeding associated with signs or symptoms of hypovolemia within 24h following the birth process regardless of mode of delivery”. PPH is an increasing cause of maternal morbidity and mortality.

May 21, 2024 · The four most common causes of PPH are known as the “Four Ts” or 4Ts: (3) Tone (80%) – uterine atony, which happens when the uterus doesn’t contract enough to clamp the blood vessels at the placental site; it may be due to a soft, weak uterus
