Chapter 25 Flashcards
One of the primaey causes of mortality associated with childbearing.
Hemorrhage
Is defined as bloos loss of 1000mL or more following a vaginal birth or cesarean birth
Postpartum Hemorrhage
The four main reasons for postpartum hemorrhage
*uterine atony
*trauma
*retained placental fragments
*disseminated intravascular coagulation
Four Ts of postpartum hemorrhage
*tone
*trauma
*tissue
*thrombin
Is the most frequent cause of postpartum hemorrhage, tends to occur in asian hispanic and black patients
Uterine atony
Are easier to locate and assess than cervical lacerations
Vaginal Lacerations
Placenta fuses with the myometrium because of an abnormal decidua basalis layer
Placenta Accreta
Is a prolapse of the fundus of the uterus through the cervix so that the uterus turns inside out
Uterine inversion
Is a deficiency in clotting ability caused by vascular injury
Disseminated Intravascular Coagulation
Is the incomplete return of the uterus to its prepregnant size and shape.
Subinvolution
Is a collection of blood below the epidermis of the vulva.
Vulvar Hematomas
Organisms commonly cultured in the postpartum period include
Group B streptococci, staphylococci, and aerobic gram negative bacilli such as escherichia coli
When is early hemorrhage
Within the first 24 hours following birth
When is late hemorrhage
From 24 hours to 6 weeks after birth
Uterine atony tends to occur most often in
Asian, Hispanic, and Black patients
In uterine atony, first step in controlling hemorrhage is
To drain the bladder and attempt fundal massage to encourage contraction
Inserts one hand into the vagina while pushing against the fundus through the abdominal wall with the other hand.
Bimanual Compression
Removal of the uterus
Hysterectomy
Lacerations occur most often:
*with difficult or precipitate births
*in primigravidas
*with the birth of a large infant
*with the use of lithotomy position and instruments
Lacerations of the cervix are usually found on
The sides of cervix, near the branches of the uterine artery.
First degree perineal lacerations
Vaginal mucous membrane and skin of the perineum to the fourchette
Second degree
Vagina, perineal skin, fascia, levator ani muscle, and perineal body.
Third degree
Entire perineum, extending to reach the external sphincter of the rectum
Fourth degree
Entire perineum, rectal sphincter, and some of the mucous membrane of the rectum
A placenta with an accessory lobe.
Succenturiate placenta
A blood serum sample of this also reveals that part of a placenta is still present.
human chorionic gonadotropin
Removal of the retained placenta can usually be accomplished by
Dilatation and Curettage (D&C)
Disseminated Intravascular Coagulation is usually associated with
*premature separation of the placenta
*missed early miscarriage
*fetal death in utero
Is the usual prescription to improve uterine tone and complete involution
Oral administration of Methylergonovine 0.2 mg four times daily
Management for vulvar hematomas
Administer an analgesic as prescribed for pain relief. Applying an ice pack may prevent further bleeding.
Is an infection of the endometrium, the lining of the uterus.
Endometritis
Is one of the first symptoms of peritonitis
Rigid abdomen (guarding)
Is inflammation of the lining of a blood vessel
Phlebitis
Is inflammation with the formation of blood clots.
Thrombophlebitis
Thrombophlebitis tends to occur because:
*smoke cigarettes
*have preexisting varicose veins
*develop a postpartum infection
*have increased parity
*have a history of a previous thrombophlebitis
This decreased circulation, along with edema gives the leg a white or drained appearance.
Femoral Thrombophlebitis
Femoral thrombophlebitis was formerly called
Milk leg or phlegmasia alba dolens (white inflammation)
Patients who are at high risk for thrombophlebitis may be prescribed ________ daily as a preventive measure.
Aspirin
If a pelvic thrombophlebitis develops, a patient will generally have
Elevated temperature, systemic fever, chills, and pain.
Management for thrombophlebitis
*Ambulation
*Well-padded stirups
*support stocking
*heparin therapy
