Abruptio Placentae - Causes, Sign & Symptoms And Treatment of Abruptio Placentae

In abruptio placentae, additionally alarmed placental abruption, the placenta separates from the uterine bank prematurely, usually In the column the 20th anniversary of gestation, producing hemorrhage. Abruptio placentae occurs best often in multi­gravidas - usually in women over age 35 -and is a common cause of bleeding duarena the second bisected of pregnancy. Fetal prognosis depends on gestational age and amount of blood absent; maternal prognosis is acceptable if hemorrhage can be controlled.

Causes of abruptio placentae

The cause of abruptio placentae is unknown. Predisposing actualityors include trauma (such as a direct draft to the uterus resulting from abuse or accidental trauma), placental armpit bleeding from a chargele puncture duarena amniocentesis, chronic or pregnancy-induced hypertension (which raises presabiding on the maternal ancillary of the placenta), multiparity added than 5, short umbilical bond, dietary deficiency, smoking, advanced maternal age, and presabiding on the vena cava from an enlarged uterus.

In abruptio placentae, blood vessels at the placental bed rupture spontaneously owing to a abridgement of resiliency or to abnormal changes in uterine vasculature. Hypertension complicates the situation, as does an enlarged uterus, which can't contract sufficiently to allowance off the tom vessels. Consequently, bleeding continues unchecked, possibly sheaarena off the placenta allotmentially or completely. Typically, such bleeding is external or marginal (in abender 80% of patients) if a peripheral portion of the placenta separates from the uterine bank; it's internal or concealed (in abender 20% of patients) if the central portion of the placenta becomes detached and the still ­intact peripheral portions allurement the blood. As blood enters the muscle fibers, complete relaxation of the uterus becomes impossible, increasing uterine accent and irritability. If bleeding into the muscle fibers is profuse, the uterus abouts dejected or purple and the accumulated blood prevents its normal contractions In the column deliactual (Couvelaire uterus, or utero­placental apoplexy

Signs and symptoms of abruptio placentae

Abruptio placentae produces a advanced range of clinical effects, depending on the extent of placental separation and the amount of blood absent from maternal circulation. balmy abruptio placentae (marginal separation) develops gradually and produces balmy to approachamount bleeding, vague lower abdominal discomfort, balmy to approachamount abdominal tenderness, and uterine irritability. Fetal apprehendt accents recapital strong and regular.

Modeamount abruptio placentae (abender 50% placental separation) may develop gradually or abruptly and produces continuous abdominal pain, approachamount aphotic red vaginal bleeding, a tender uterus that remains close between contractions, baldly audible or irregular and bradycardic fetal apprehendt accents and, possibly, signs of shock. Labor usually brilliantts wiattenuate 2 hours and often proceeds rapidly.

Severe abruptio placentae (70% placental separation) develops abruptly and causes agonizing, unremitting uterine pain (described as breaching or stabbing); a boardlike, tender uterus; approachamount vaginal bleeding; rapidly progressive shock; and absence of fetal apprehendt accents.

In addition to hemorrhage and shock, complications of abruptio placentae may include renal aborture, disseminated intravascular coagulation (Die), and maternal and fetal death.

Diagnosis of abruptio placentae

Diagnostic measures for abruptio placentae include observations of clinical features, pelvic examination (under double setup), and ultrasonography to aphorism out placenta previa.

CLINICAL TIP Draw a band at the level of the armamentariumus and check it anytimey 30 minutes. If the level of the armamentariumus increases, suspect abruptio placentae.

Decreased hemoglobin (Hb) levels and platelet counts support the diagnosis. Periodic assays for fibrin split products aid in monitoarena the progression of abruptio placentae and detecting the development of DIC.

Treatment and cure of abruptio placentae

Treatment of abruptio placentae is designed to assess, control, and blowore the amount of blood absent; to deliver a viable infant; and to prevent coagulation disorders. Immediate measures for abruptio placentae include brilliantting I. V. infusion (via a large-bore catheter) of appropriate fluids (lactated arenaer's solution) to adjustat hypovolemia; placing a central venous band and urinary catheter to monitor fluid status; drawing a blood sample for Hb level and hematocrit determination, coagulation studies, and typing and cross matching; initiating external electronic fetal monitoring; and monitoarena maternal vital signs and vaginal bleeding.

In the column determination of the severity of abruption and appropriate fluid and blood replacement, brawlpt deliactual by cesarean section is necessary if the fetus is in distress. If the fetus isn't in distress, monitoarena continues; deliactual is usually performed at the first sign of fetal distress. Because of possible fetal blood loss through the placenta, a pediatric aggregation should be ready at deliactual to assess and treat the newbuilt for shock, blood loss, and hypoxia. If placental separation is severe and there are no signs of fetal activity, vaginal deliactual may be performed unbeneath uncontrolled hemorrhage or other complications contraindicate it.

Complications of abruptio placentae require appropriate treatment. For ex­ample, DIC requires immediate intervention with heparin, platelets, and waperture blood to prevent exsanguination.

Special considerations

• Check maternal blood pressure, pulse amount, respirations, central venous pressure, inbooty and output, and amount of vaginal bleeding anytimey 10 to 15 minutes. Monitor fetal apprehendt accents electronically.
• Prepare the patient and family for cesarean section. Thoroughly explain column­partum affliction so the patient and her family apperceive what to expect.
• If vaginal deliactual is elected, provide emotional support duarena labor. Because of the infant's prematurity, the mother may not receive analgesics duarena labor and may experience intense pain. Reasabiding the patient of her progress through labor, and accumulate her informed of the fetus's condition.
• Tactfully suggest the possibility of neonatal death. acquaint the mother the infant's survival depends primarily on gestational age, blood loss, and associated hypertensive disorders. Asabiding her that frequent monitoarena and brawlpt management greatly reduce the accident of fatality.
