Study Notes
Definitions and Classifications of Postpartum Hemorrhage (PPH)
- PPH traditionally defined: Vaginal Spontaneous Delivery (VSD) blood loss ≥ 500 mL; Cesarean Section (CS) blood loss ≥ 1000 mL.
- American College of Obstetricians and Gynecologists (ACOG, 2017) revised definition: PPH as blood loss ≥ 1000 mL with hypovolemia symptoms.
- PPH classification includes early (within 24 hours post-delivery) and late (after 24 hours post-delivery).
Causes of Insufficient Uterine Contractions
- Distortion, uterine myomas, and placenta previa affect uterine contractions.
- Diagnosis of conditions such as chorioamnionitis and uterine abnormalities is crucial during prenatal checkups.
Management and Evaluation
- Steps include inspecting the placenta for completeness and massaging the uterus.
- Uterotonics are administered to promote uterine contraction.
- Retained placental tissue can impair contractions, necessitating careful examination.
Surgical and Non-Surgical Interventions
- Non-surgical management includes bimanual uterine compression and balloon tamponade.
- In severe cases, surgical interventions may include total hysterectomy or procedures to conserve fertility, e.g., uterine artery ligation.
- Complications of procedures can include uterine ischemic necrosis and infection.
Types of Placental Abnormalities
- Accessory placental lobe (placenta succenturiata) can cause complications if vasculature traverses membranes.
- Inspection for abnormal blood vessel formations is critical during delivery to identify issues potentially leading to hemorrhage.
Angiographic Embolization
- Used for intractable hemorrhage when surgical access is challenging; does not impair fertility.
- Possible complications: iatrogenic iliac artery rupture, uterine ischemic necrosis, and uterine infection.
Risk Factors for Abruptio Placenta
- Conditions such as preeclampsia contribute to the risk of abruptio placenta.
- Coagulation alterations are a significant complication, potentially leading to inadequate clot formation.
Importance of Timing and History
- Identifying the timing of hemorrhage is essential as it guides immediate management.
- Comprehensive medical history related to previous deliveries and uterine surgeries is vital for assessing risk factors for complications like uterine rupture.
Goals During the Third Stage of Labor
- Aim for safe delivery of the placenta while preventing uterine inversion and postpartum hemorrhage.
- Immediate interventions for persistent bleeding despite a contracted uterus signal the need for further evaluation.
