[Exam 2] Chapter 22 – Nursing Management of the Postpartum Woman at Risk Flashcards
Postpartum Hemorrhage: What is this
Potentially life-threatening complication that can occur after both vaginal and cesarean births
Postpartum Hemorrhage: At what time do these post often occur?
Within 4 hours of childbirth
Postpartum Hemorrhage: What is this defined as?
Blood loss greater than 500 mL after vaginal birth, and more than 1000 mL loss after a cesarean birth
Postpartum Hemorrhage: Morbidity is severe, with what happening in body because of this?
Organ failure, shock, edema, thrombosis, acute respiratory distress, sepsis, anemia, and prolonged hospitalization
Postpartum Hemorrhage: Major obstetric hemorrhage is defined as
Blood loss of more than 1500 - 2500 mL or bleeding that requires more than 5 units of transfused blood
Postpartum Hemorrhage: What is primary postpartum hemorrhage?
Blood loss that occurs within 24 hours of birth
Postpartum Hemorrhage: What is delayed postpartum hemorrhage?
Blood loss that occurs 24 hours to 12 weeks after birth
Postpartum Hemorrhage Patho: Most common cause of this?
Uterine atony, the failure of the uterus to contract and retract after birth.
Postpartum Hemorrhage Patho: How must uterus remain after birth?
Contracted to control bleeding from the placental site
Postpartum Hemorrhage Patho: What makes up 20% of the reasons for this?
Obstetric lacerations, uterine inveresion, adn rupture compromise
Postpartum Hemorrhage Patho: What do the muscles of the uterus do during the third stage?
Contract downward, causing constriction of the blood vessels that pass through uterine wall, stopping flow of blood. Causes placenta to separate from uterine wall.
Postpartum Hemorrhage Patho: Absence of uterine contractions may result in what
excessive blood loss
Postpartum Hemorrhage Patho: What do Uterotonic medication spromote/
Uterine contractions to prevent atony and speed delivery of the placenta
Postpartum Hemorrhage Patho: Blood volume increases by how much during pregnancy?
50%, causing Hct and Hgb to fall. Provides reserve for blood loss during delivery.

2100 mL of blood has been lost.
Postpartum Hemorrhage Patho: Current evidence of postpartum volume replacement suggests what?

Postpartum Hemorrhage Patho: What is included in Tone?
Uterine tony, Distended Bladder
Postpartum Hemorrhage Patho: What is included in Tissue?
Retained placenta and clots; uterine subinvolution
Postpartum Hemorrhage Patho: What is included in Trauma?
Lacerations, hematoma, inversion, rupture
Postpartum Hemorrhage Patho: what is included in Thrombin?
Coagulopathy (preexisting or acquired)
Postpartum Hemorrhage and Tone: What causes tone to change?
From overdistention of the uterus. Can be caused by multiple gestation, fetal macrosomia, hydramnios, and placenta previa . Could also be prolonged or rapid, forceful labor if stimulated by oxytocin
Postpartum Hemorrhage and Tone: Uterine atony can lead to what?
Hypovolemic shock.
Postpartum Hemorrhage and Tone: Distended bladder can cause what problem?
Can displace the uterus from the midline to either side, which impedes its ability to contract to reduce bleeding
Postpartum Hemorrhage and Tissue: What happens when the placenta fails to seprate?
Leads to retained fragments, which occupy space and prevent the uterus from contracting fully to clamp down on blood vessels. Clots can also occupy this space
Postpartum Hemorrhage and Tissue: Tears or fragments left inside the woman may indicate what?
Accessory lobe or placenta accreta(uncommon condition where chorionic villi adhere to the myometrium causing the placenta to adhere abnormally)
Postpartum Hemorrhage and Tissue: What does subinvolution refer to?
Incomplete involution of the uterus or failure to return to its normal size and condition after birth.
Postpartum Hemorrhage and Tissue - Subinvolution: What causes this to occur?
When the myometrial fibers of the uterus do not contract effectively and causes relaxation.
Postpartum Hemorrhage and Tissue - Subinvolution: Complictions of this?
Hemorrhage, pelvic peritonitis, salpingitis, and abscess formation
Postpartum Hemorrhage and Tissue - Subinvolution: Causes of this?
Retained placental fragments, distended bladder, excessive maternal activity, uterine myoma, and infection
Postpartum Hemorrhage and Tissue - Subinvolution: How does the fundus feel here and lochia?
Fundus higher than expected, and boggy.
Lochia fails to change colors from red to serosa to alba within a few weeks
Postpartum Hemorrhage and Tissue - Subinvolution: Treatment for this?
Stimulating the uterus to expel fragments with a uterine stimulant, and antibiotics given to prevent infection
Postpartum Hemorrhage and Trauma: What type of trauma would be included here?
Lacerations and hematomas.
Postpartum Hemorrhage and Trauma: What can hemoatomas present as?
Pain or as change in VS disproporionate to amount of blood loss. Associated with episiotomy, instrumental birht, or nulliparity.
Postpartum Hemorrhage and Trauma: When does uterine inversion happen?
When the top of the uterus collapses into inner cavity due to excessive fundal pressure or pulling on the umbilical cord when placenta still firmly attached to fundus
Postpartum Hemorrhage and Trauma: Tx for uterine inversion?
Giving uterine relaxants and immediate manual replacement by the health care provider
Postpartum Hemorrhage and Thrombin: Why is this a problem?
Disorders that interfere with clot formation which can lead to hemorrhage
Postpartum Hemorrhage and Thrombin: Abnormal results from coagulation studies typically include what?
decreased platelet and fibrinogen levels
Increased prothrombin time
Partial thromboplastin time
Fibrin degradation products
