Final answer:
Medical emergencies that require immediate postpartum treatment include inversion of the uterus and hypovolemic shock, which can stem from issues like retained placental fragments leading to postpartum hemorrhage.
Step-by-step explanation:
Postpartum conditions that are considered medical emergencies requiring immediate treatment include inversion of the uterus and hypovolemic shock. Inversion of the uterus is a rare but serious complication where the uterus turns inside out, often following childbirth. Hypovolemic shock, a type of circulatory shock, occurs due to excessive loss of blood volume, which can result from severe postpartum hemorrhage.
Postpartum hemorrhage is a risk when fragments of the placenta remain in the uterus after delivery, which is why it is crucial for an obstetrician to examine the expelled placenta and fetal membranes to ensure they are intact. The continued contraction of the uterus, known as involution, is essential for reducing blood loss and returning the body to its pre-pregnancy state. Effective management of these conditions typically includes prompt resuscitation with intravenous fluids and medications to restore blood pressure and volume, and in the case of retained placenta, manual removal or surgery may be required.
