High Risk Pregnancy

Slide 2 -

Introduction Many complications can occurs during pregnancy and affect health of mother and fetus as well as outcomes Hemorrhage is the first ten causes of maternal mortality and morbidity affect about 32% of all maternal death. Abortion represent 4.5% of all maternal death Many women do not understand the bleeding is abnormal and dangerous signs and come late to health care facilities

Slide 3 -

High Risk Condition Bleeding in early pregnancy. Bleeding in late pregnancy ( ante partum hemorrhage). Pregnancy induced hypertension. Diabetes Mellitus.

Slide 4 -

1-Bleeding In Early Pregnancy (Before 20 weeks Gestation) Causes Abortion. Vesicular mole. Ectopic pregnancy. Local lesions — cervical polyps — cervical cancer.

Slide 5 -

Abortion It is the termination of pregnancy before 24 weeks, or products of conception weighing below 500 grams. The termination is either spontaneous or induced,befor the fetus develops sufficiently to survive

Slide 6 -

Incidence Spontaneous abortion occurs in 10-15% of pregnancy , 80% of them occur in the first trimester.

Slide 7 -

Causes 50%-80% of abortions in the first 12 weeks of pregnanacy result from Chromosomal anomalies. Fetal Chromosomal anomalies. Diseases of the fertilized ovum. Hypoxia. Maternal Infections e.g. influenza, malaria, syphilis ,HIV. Disease such as chronic nephritis,TB. Drug intake during pregnancy. Rh and ABO incompatibility. Incompetent cervix. Uterine malformation. Aquired uteine defect as uterine fibroid or adhesions Trauma - criminal interference, Endocrinal disorder as hypothyrodism , daibetes mellitus

Slide 8 -

Pathology of abortion First 8 weeks gestation Separation of decidua basalies and expulsion of the ovum If retained within the uterus, the ovum becomes surrounded by decidua and blood clot 8-12 weeks of gestation Rupture of decidua capsularis and explusion of the product of conception After 12 weeks Rupture of membernes followed explusion of the product of fetus and the placenta retained in uterus

Slide 9 -

Types of Abortion Spontaneous abortion Threatened abortion: Missed abortion Inevitable abortion Complete abortion Incomplete abortion Habitual abortion Therapeutic abortion Criminal abortion Septic abortion

Slide 10 -

Signs and Symptoms of Abortion Threatened abortion: Cervical os is closed. Membranes are intact. Pain and backache may or may not be present. Treatment Complete bed rest Avoid enema &constipation no sexual intercourse Administration of prescribed drugs

Slide 11 -

Incomplete abortion Severe bleeding. Cervical os partly closed. No uterine involution. Pain may or may not be present. Uterus is soft and smaller than the expected period of pregnancy.

Slide 12 -

Septic abortion: Tender and painful uterus. Offensive vaginal bleeding. High temperature.Rapid pulse. .Unstable blood pressure. Shock. Treatment Isolation. Clinical bacteriological to identify the infectious organisms. Administration of antibiotics as doctor orders. Intake and output chart should be kept. The soiled pads should be properly collected and burned

Slide 13 -

Inevitable abortion Bleeding is excessive (more than 10 days). Blood is red in color with clots. Severe colicky lower abdominal pain. Cervical os is dilated and rupture of membranes has occurred. There is severe blood loss and the woman becomes shocked. Treatment Hospitalization If no heart beats are detected a dilute solution of oxcytocin may be given as the doctor orders to help in the expulsion of the contents of the uterus. Dilatation and curettage should be done.

Slide 14 -

Missed abortion Some signs of pregnancy disappear. Pregnancy test will be negative. Fundal height does not increase in size. The breasts may secrete milk due to hormonal changes FHR are absent. No fetal movement. A sonar test confirms fetal death. Some brownish vaginal discharge Complication of missed abortion 1- Hypofibrinogenemia(DIc) 2- Infection leads to septic abortion, septicemia, septic shock and death

Slide 15 -

Habitual abortion: May be due to: Cervical incompetence. Poor nutritional status. Hormonal disturbance. Defective ova or spermatozoa. Rh incompatibility. Chronic nephritis. Treatment of the cause such as cervical incompetence or treatment of causative diseases as syphilis, DM, etc.

Slide 16 -

Complete abortion: There is minimal bleeding. Pain stops. Uterus is hard and much smaller The cervix is closed

Slide 17 -

Nursing Management of Abortion Prevention measures should be taken to avoid risk of a spontaneous abortion. A nutritional diet. Avoiding smoking or drinking. Receiving available immunizations against infectious diseases. Treatment of vaginal or pelvic infections.

Slide 18 -

Hydatidiform Mole (Vesicular Mole) Hydatidiform mole is a gross malformation of the trophoblast in which the chorionic villi proliferate and become avascular.

Slide 19 -

Causes The exact cause is unknown. Risk factors are: Maternal age above 40 years or below 19 years. Malnutrition Types 1- partial mole 2- complete mole

Slide 20 -

Signs and Symptoms Excessive frequent vomiting. Over distension of the uterus and larger than expected for weeks of gestation. Some vaginal bleeding may occur plus vesicles. No fetal movements ,No fetal parts Positive pregnancy test result in highly diluted urine 1:500.

Slide 21 -

Complications Hemorrhage. shock perforation Uterine sepsis. Choriocarcinoma

Slide 22 -

Management Admit the woman into hospital. evacuation of the uterus under general anesthesia. Health education on the following: Need for monitoring HCG levels for two years (monthly for the first 3 months, then every three months for one year). Birth spacing methods to prevent pregnancy for two years. If HCG levels remain more than five international units per liter eight weeks postpartum, prophylactic chemotherapy is indicated.

Slide 23 -

Ectopic Pregnancy pregnancy occurring outside the normal uterine cavity Ectopic pregnancy usually occurs 99% of cases in the uterine tube.

Slide 24 -

Tubal Pregnancy Causes Impaired tubal ciliary action. Impaired tubal contractility. Decreased sperm mobility. The use of intrauterine contraceptive device.

Slide 25 -

Risk Factors Pelvic inflammatory disease. History of previous pelvic operations such as D and C, ovarian surgery.

Slide 26 -

Signs and Symptoms Short periods of amenorrhea. Sudden/recurrent severe, colicky abdominal pain in one iliac fossa or entire lower abdomen. Blood stained vaginal discharge. Signs of shock. Dyspareunia.

Slide 27 -

Possible Outcomes of Tubal Pregnancy Tubal abortion. Tubal mole. Tubal rupture.

Slide 28 -

Management Evacuated immediately. Salpingectomy is preformed. Provide emotional support. Follow-up is needed. Family planning should be discussed.

Slide 29 -

Bleeding in late pregnancy Antepartum hemorrhage is defined as bleeding from the genital tract between 28th week of pregnancy and onset of labor. Classification Placenta previa Abruptio placenta Extraplacental bleeding (cervical polyp)

Slide 30 -

Placenta Previa placenta is partly or totally implanted over the lower uterine segment.

Slide 31 -

Causes No specific cause can be detected for most of the cases, while the predisposing factors are: Large placenta previous uterine scarring Multipara

Slide 32 -

Incidence Occurs in 5% of all pregnancies.

Slide 33 -

Degrees Placenta previa lateralis Placenta previa marginalis Incomplete central placenta previa: Complete central placenta previa

Slide 34 -

Effects of Placenta Previa on Pregnancy and Labor Abnormal presentation and position. Premature labor. Prolonged labor. More chance of surgical intervention. Placenta may be adherent Postpartum hemorrhage. Fetal malformation. High incidence of fetal hypoxia and mortality. Maternal shock. Maternal death.

Slide 35 -

Management in Hospital Conservative treatment If bleeding is slight, observe carefully and correct anemia) Active treatment if Bleeding is slight. The placenta is of the first or second degree. The fetus lies longitudinally. The patient is in labor, with good uterine contraction.

Slide 36 -

Cesarean section is indicated if: The patient has lost a large amount of blood. Placenta of third and fourth degrees. Old primigravida or multipara. Posterior placenta prevla.

Slide 37 -

Role of the Nurse Bed rest and restriction of physical activity for at least 24 hours after admission. Avoid constipation, enemas, and vaginal and rectal examinations Follow strict aseptic technique to avoid infection. Continuous observation of bleeding and signs of shock. listening FHR every 4 hours. accurate recording of intake and output.

Slide 38 -

Abruptio Placenta (Accidental Hemorrhage) bleeding during the last three months of pregnancy, the first or second stage of labor, due to premature separation of a normally situated placenta

Slide 39 -

Causes The most important cause is hypertension. The second most common cause is trauma deficiencies in vitamins C and K. Traction on a short umbilical cord. Sudden reduction of the size of the uterus.

Slide 40 -

Types Revealed: almost all the blood expelled through the cervix. Concealed: almost all the blood is retained inside the uterus. Combined: some blood is retained inside the uterus and some is expelled through the cervix.

Slide 41 -

Complications Shock. Acute renal failure. Postpartum hemorrhage. Consumption coagulopathy

Slide 42 -

Management Treatment of toxemia. Replacement of blood loss. Treatment for shock. Obstetric treatment: In the presence of painful uterine contractions: artificial rupture of membranes. In the absence of labor pain: IV syntocin drip. When labor pains are established: the treatment is continued as above. When the drip is a failure, a cesarean section must be done

Slide 43 -

Role of the Nurse Continuous observation of patient’s general condition, blood pressure, vital signs, bleeding and signs of shock. Continuous observation of fetal condition. Initiation and continuous observation of IV transfusion. Give medications accurately, especially for hypotension and shock if present. Regular urine analysis for proteinuria. Assessment and recording of intake and output. Assist in vaginal delivery, ◘ Provide pre-operative care Provide post-operative care.
