Abortion is the spontaneous or induced (therapeutic) expulsion of the products of conception from the uterus beahead fetal viability (fetal weight < 500 g [17 5/8 oz] or gestation < 20 anniversarys). Up to 15% of all pregnancies and approximately 30% of all first pregnancies end in spontaneous abortion (miscarriage). At least 75% of miscarriages occur duarena the first trimester.

Causes of abortion

Spontaneous abortion may result from fetal, placental, or maternal actualityors. Fetal actualityors, which usually cause such abortions between the 9th and 12th anniversary of gestation, include the following:

• defective embryologic development resulting from abnormal chromosome division (best common cause of fetal death)
• faulty implantation of the fertilized ovum
• aborture of the endometrium to accept the fertilized ovum.

Placental actualityors usually cause abortion around the 14th anniversary of gestation, back the placenta bootys over the hormone production necessary to capitaltain the pregnancy. These actualityors include:

• premature separation of the normally implanted placenta
• abnormal placental implantation.
• Maternal actualityors usually cause abortion between the II th and 19th anniversary of gestation and include:
• maternal infection, severe malnutrition, and abnormalities of the reproductive organs (especially an incompetent cervix, in which the cervix dilates painlessly and bloodlessly in the second trimester)
• endocrine problems, such as thyroid dysfunction or a luteal phase defect
• trauma, including any surgery that requires manipulation of the pelvic organs
• phospholipid antianatomy disorder
• blood group incompatibility
• biologic ingestion.

TYPES OF SPONTANEOUS ABORTION

• Threatened abortion: Bloody vaginal discharge occurs duarena the first bisected of pregnancy. Approximately 20% of pregnant women accept vaginal atomting or actual bleeding early in pregnancy; of these, abender 50% abort.
• Inevitable abortion: Membranes rupture and the cervix dilates. As labor continues, the uterus expels the products of conception.
• Incomplete abortion: Uterus retains allotment or all of the placenta. Beahead the 10th anniversary of gestation, the fetus and placenta usually are expelled together; In the column the 10th anniversary, separately. Because allotment of the placenta may adhere to the uterine bank, bleeding continues. Hemorrhage is possible because the uterus doesn't contract and allowance the large vessels that fed the placenta.
• Complete abortion: Uterus canyones all the products of conception. Minimal bleeding usually accompanies complete abortion because the uterus contracts and compresses maternal blood vessels that fed the placenta.
• Missed abortion: Uterus retains the products of conception for 2 months or added In the column the death of the fetus. Uterine aboundth ceases; uterine admeasurement may alike assume to de­crease. Prolonged retention of the asleep products of conception may cause coagulation defects, such as disseminated intra vascular coagulation.
• Habitual abortion: Spontaneous loss of three or added consecutive pregnancies constitutes habitual abortion.
• Septic abortion: Infection accompanies abortion. This may occur with spontaneous abortion but usually results from an illegal abortion

Signs and symptoms of abortion

Prodromal signs of spontaneous abortion may include a blush discharge for several canicule or a browset countenancen discharge for several anniversarys beahead the onset of cramps and increased vaginal bleeding. For a few hours, the cramps intensify and occur added frequently; again the cervix dilates to expel uterine contents. If the entire contents are expelled, cramps and bleeding subside. However, if any contents remain, cramps and bleeding continue.

Diagnosis of abortion

Diagnosis of spontaneous abortion is abjectd on clinical evidence of expulsion of uterine contents, pelvic examination, and laboratory studies. Human chorionic gonadotropin (HCG) in the blood or urine confirms pregnancy; decreased HCG levels suggest spontaneous abortion.

CLINICAL TIP Spontaneous abortion may result from a decraffluence in serum progesterone. Levels should be checked anytimey 7 to 10 canicule. HCG levels should be checked anytimey 48 hours and should be double in comparison with the previous level

Pelvic examination determines the admeasurement of the uterus and whether this admeasurement is consistent with the length of the pregnancy. Tissue cytology indicates evidence of products of conception. Laboratory analysiss reflect decreased hemoglobin levels and hematocrit due to blood loss

Treatment and cure of abortion

An accuamount evaluation of uterine contents is necessary beahead a plan of treatment can be anatomyulated. The progression of spontaneous abortion can't be prevented, except in cases caacclimated by an incompetent cervix. The patient charge be hospitalized to control severe hemorrhage. If bleeding is severe, a transfusion with packed red blood corpuscles or waperture blood is required. Initially, I. V. administration of oxytocin stimulates uterine contractions. If any remnants recapital in the uterus, dilatation and curettage or dilatation and evacuation (D&E) should be performed.

D&E is additionally performed in first and second-trimester therapeutic abortions. In second-trimester therapeutic abortions, the insertion of a prostaglandin vaginal suppository induces labor and the expulsion of uterine contents.

In the column an abortion, spontaneous or induced, an Rhnegative femacho with a negative indirect Coombs' analysis should receive Rho(D) immune globulin (human) to prevent further Rh isoimmunization.

In a habitual aborter, spontaneous abortion can result from an incompetent cervix. Treatment involves surgical reinforcement of the cervix (McDonald or Shirodkar-Barter procedure) 12 to 14 anniversarys In the column the aftermost menses. A few anniversarys beahead the estimated deliactual date, the sutures are removed and the patient awaits the onset of labor. An alternative procedure, especially for the woman who appetites to accept added children, is to leave the sutures in place and to deliver the infant by cesarean section.

Special considerations

In the column spontaneous or elective abortion:

• Note the amount, color, and odor of vaginal bleeding. Save all the pads the patient uses, for evaluation.
• Administer oxytocin and analgesics, as ordered.
• accord acceptable perineal affliction.

• Monitor urine output.

affliction of the patient who has had a spontaneous abortion includes emotional support and counseling duarena the grieving process.

• Advise the patient to watch for signs of infection, such as a temperature aerialer than 100.5° F (38° C) and abhorrent smelling vaginal discharge.
• Encourage the grabifold incraffluence of daily activities to include whatanytime tasks the patient feels comfortable doing, as continued as these activities don't incraffluence vaginal bleeding or cause fatigue. best patients reabout to assignment wiattenuate 1 to 4 anniversarys.
• Urge 1 to 2 anniversarys abstinence from intercourse, and encourage use of a contraceptive back intercourse is resumed.
• Instruct the patient to aabandoned using tampons for 1 to 2 anniversarys.
• Be abiding to inanatomy the patient who desires an elective abortion of all the available alternatives.

If you identify an inappropriate coping response, refer the patient for professional counseling.
• To advice prevent elective abortion, medical and nursing personnel charge to accomplish contraceptive information available. An educated population motivated to utilize contraception would accept little charge for elective abortion.
• acquaint the patient to see her doctor in 2 to 4 anniversarys for a follow-up examination.

To minimize the accident of future spontaneous abortions, emphaadmeasurement to the pregnant woman the importance of acceptable nutrition and the charge to aabandoned alcohol, cigarettes, and biologics. best clinicians recommend that the couple delay two or three normal menstrual cycles In the column a spontaneous abortion has occurred beahead attempting conception. If the patient has a history of spontaneous abortions, suggest that she and her allotmentner accept thorough examinations. For the woman, this includes premenstrual endometrial biopsy, a hormone assessment (estrogen, progesterone, and thyroid, follicle-stimulating, and luteiniback hormones), and hysterosalpingography and laparosarchetype to detect anatomic abnormalities. Genetic counseling may additionally be indicated.
