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:
Trauma: Injury during delivery.
Uterine atony: Failure of the uterus to contract effectively.
Retained placenta: Placenta does not detach fully from the uterine wall.
Coagulation disorders: Issues that affect blood clotting.
Secondary PPH Causes:
Retained products of conception: Pieces of the placenta or membranes left inside.
Infections: Particularly if labor was complicated.
Cervical lacerations: Injury to the cervix during delivery.
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
Shock due to significant blood loss.
Disseminated Intravascular Coagulation (DIC): A coagulation disorder contributing to or arising from severe bleeding.
Sheehan's Syndrome: Results from pituitary gland necrosis caused by severe blood loss, leading to hormonal deficiencies.
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.
