|
atony
|
absence or lack of muscle tone
|
|
|
dilations and curettage (D&C)
|
stretching of the cervical os to permit suctioning or scraping of the walls of the uterus. Procedure is performed to obtain samples of uterine lining tissue for lab exam, during pp period to remove retained placental fragments and in abortion.
|
|
|
embolus
|
mass that may be composed of a thrombus or amniotic fluid released into bloodstream to cause obstruction of pulmonary vessels
|
|
|
hematoma
|
localized collection of blood in a space or tissue
|
|
|
hydraminos
|
excess volume of amniotic fluid (>2000ml). Also called "polyhyraminos".
|
|
|
hypovolemic shock
|
acute peripheral circulatory failure caused by loss of circulating blood volume
|
|
|
mastitis
|
infection of the breast
|
|
|
metritis
|
infection of decidua, myometrium, and parametrial tissues of the uterus
|
|
|
placenta accreta
|
placenta that is abnormally adherent to uterine wall. If the condition is more advanced, it is called "placenta increta" (the placenta extends into the uterine mm.) or "placenta percreta" (the placenta extends thru the uterine mm.)
|
|
|
subinvolution
|
slower than expected return of the uterus to its nonpregnancy size after childbirth
|
|
|
thrombus
|
collection of blood factors, primarily platelets and fibrin, that may cause vascular obstruction.
|
|
|
early postpartum hemorrhage
|
- occurs during the first 24 hours after childbirth
- most often caused by uterine atony |
|
|
major signs of uterine atony
|
-uterine fundus that is difficult to locate
-soft or "boggy" feel -is firm when massaged but loses its tone when massage is stopped -excessive lochia or clots expelled |
|
|
predisposing factors to pp hemorrhage
|
-overdistention of uterus (multiple gest., lg. infant, hydraminos)
-multiparity -trauma to birth canal (lg. baby, lacerations, hematomas -use of tocolytic drugs -precipitate labor/delivery -use of forceps or vacuum -CB -manual removal of placenta -general anesthesia -drugs: oxytocin, prostaglandins, Mg sulfate -chorioamnionitis -uterine inversion |
|
|
early signs of pp hemorrhage
|
-uncontracted uterus
-lg. gush, trickle, ooze or seeping blood from the vagina -saturation of >1 peripad per 15 min -tachycardia |
|
|
Hypovolemia
|
-occurs when too much blood is loss and compensation occurs thru the release of catecholamines - leading to vasoconstriction and incr. HR & BP
-tachycardia is one of the earliest signs of hypovolemic shock |
