Overview of Postpartum Hemorrhage (PPH)

Definition of Postpartum Hemorrhage (PPH)

  • Postpartum hemorrhage is classified based on the timing and amount of blood loss.

  • Primary PPH occurs within the first 24 hours after delivery.

  • Secondary PPH occurs after 24 hours up to 6 weeks postpartum.

Types of Postpartum Hemorrhage

  • Primary PPH:

    • Defined as blood loss of 500 mL or more after vaginal delivery or 1000 mL after a cesarean section.

    • Causes symptoms of deterioration in the mother's condition even with smaller volumes of blood loss.

    • Requires urgent care classification.

  • Secondary PPH:

    • Usually occurs after the first week to the beginning of the second week postpartum.

    • Includes retrospective classifications of bleeding that occurs due to retained products of conception or infections.

Causes of Postpartum Hemorrhage

Primary PPH Causes:

  1. Trauma: Injury during delivery.

  2. Uterine atony: Failure of the uterus to contract effectively.

  3. Retained placenta: Placenta does not detach fully from the uterine wall.

  4. Coagulation disorders: Issues that affect blood clotting.

Secondary PPH Causes:

  1. Retained products of conception: Pieces of the placenta or membranes left inside.

  2. Infections: Particularly if labor was complicated.

  3. Cervical lacerations: Injury to the cervix during delivery.

  4. Anticoagulation drugs: Use of drugs such as heparin, which prevent blood clotting.

Management of Postpartum Hemorrhage

Prevention in the First Stage of Labor

  • Avoid prolonged latent phase; manage labor actively to prevent unnecessary pain and stress.

    • Analgesics should be given when necessary to control pain.

    • Monitor cervix dilation closely to prevent complications associated with late delivery.

Management in Second Stage of Labor

  • Ensure cervix is fully dilated before encouraging the mother to bear down during the delivery.

  • Deliver the fetal head slowly between contractions to avoid trauma and reduce risk of perineal tears.

  • Consider an episiotomy when necessary to avoid impending tears.

Management in Third Stage of Labor

  • Check for signs of placenta separation; administer oxytocin as per hospital protocol to stimulate uterine contraction and reduce bleeding.

  • Inspect the perineum for potential tears; suture if necessary.

  • Perform a thorough check of the placenta for any retained lobes.

  • Ensure all procedures are conducted under aseptic techniques to prevent infection.

Manual Removal of the Placenta

  • If bleeding is noted and the placenta is partially detached, aseptic manual removal may be necessary.

    • Position the dominant hand to locate the attached area while supporting the uterine fundus with the non-dominant hand.

    • Sweep the placenta away gently from the uterine wall before removal.

Post-management Considerations

  • Antibiotic prophylaxis should be administered to prevent infection after manual removal.

  • Monitor the mother's hemoglobin levels to assess for anemia due to blood loss.

  • Encourage breastfeeding to promote uterine contraction through the release of oxytocin.

Classification of PPH

  • Atonic PPH: Characterized by dark red blood loss in clots and a bulky, poorly contracting uterus.

  • Traumatic PPH: Recognized by a continuous bright red bleeding pattern with a well-contracted uterus, indicating trauma as the source.

Treatment Protocol for Atony PPH (Acronym: PHONING + S)

  • P: Position the mother appropriately.

  • H: Help the uterus contract (massage).

  • O: Optimize uterine volume (empty bladder).

  • N: Notify the healthcare team.

  • I: Initiate intravenous fluids and medications such as oxytocin.

  • N: Note patient progress constantly.

  • G: Get ready for possible blood transfusions.

Steps to Take for Severe Cases

  • Use calcium gluconate prior to transfusion of blood components if the patient has lost significant blood volume and before the third pint of blood is administered.

  • Monitor signs of disseminated intravascular coagulation (DIC) and renal shutdown during management.

Complications of PPH

  1. Shock due to significant blood loss.

  2. Disseminated Intravascular Coagulation (DIC): A coagulation disorder contributing to or arising from severe bleeding.

  3. Sheehan's Syndrome: Results from pituitary gland necrosis caused by severe blood loss, leading to hormonal deficiencies.

  4. Renal failure: Can result from lack of blood flow due to severe bleeding.

Questions for Discussion

  • What are key signs of PPH that healthcare workers need to monitor for?

  • How does the management of a patient with hypofibrinogenemia differ from that of standard PPH?

  • What is the role of antibiotics in management after manual labor procedures?

  • Why is the differentiation between atonic and traumatic PPH critical for appropriate management?

Conclusion

  • Continual assessment and careful management are crucial in preventing and treating postpartum hemorrhage.

  • Understanding the causes, types, and management protocols can significantly improve maternal outcomes in a clinical setting.
