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
