Report On Induced Abortion –methods Of Termination Of Pregnancy Till 12 Wks Of Gestation , Pre Abortion Counseling

pg-1 Report on Induced abortion –methods of termination of pregnancy till 12 wks of gestation , pre abortion counseling Def…. deliberate artificial termination of pregnancy until 22 ges. wks in a manner that ensures that the embryo\ fetus does not survive, I incidence- 1:4 preg world wide. Classification;1. early-till 12wks. –late-12-22wks 2.medical/planned-●decided by mother. no risk for preg. -●due to complications of preg.(therapeutic) maternal risk associated with contraction of preg/ fetal abortion associated with genetic chromosome structural defects note; chromosome defect anencephaly, down, fetal malformations ●w/out compli- malignancy, syphilis, rubella, cmv, hiv, hf, pulmonary failure ,kidney problems. 3.surgical medical indications preg<22wks ●,continuance of preg would involve risk to the life of mother greater than if the preg was terminated. ● termination to prevent physical/ mental health ,injury of preg female or existing child of family. ●substantial risk if child born for physical/mental abnormalities. 4. On request of mother. 5. Social factors. Methods • Early surgical – 1.D&C 2.vaccum curettage till 5-6 wks maximum. • Medical – 3. RU 486 (mifepristone) – antiprogesterone, 4.Laminaria – if products of conception are large. Note:- Ru 486 – 400 – 600 μg – p/o followed in 36 – 48 hrs i/m or vaginal prostaglandin analog, Used for preg < 7wks 79% effective. - Methotrexate with Misoprostol (pg) – 800 μg 1wk +/- require ….cuation later i/vaginal a/f 2wks (single) at 8wks Embryo’s expected Spontaneously if not check hCG 50mg/m³, 90% effective level If abortion fails within 36hrs, PgE, methylester pesary (Gemeprost 1mg vaginaly to complete abortion, process Misoprostol (Pg…) •

Surgical: Done under local anesthesia / light general D&C: o Tapered dilatators in progressively ↑in size with the Ø of the …cannula is real size of the cannula correlates with gestational age, o Laminaria in cervical canal atleast for 4+ or overnight, o Prostaglandin E1 analogue. After dilation curette is inserted and taken out usually performed after 7 – 12 wks. D&E is performed from 12 – 18 wks.

Methods of late abortion: 1. Vaginal prostaglandins:  Gemeprost vagitorium (Pg E1 analogue),(Cergem) 1mg every 3 hours until abortion has happened (+vacuum curettage)  Misoprostol (Pg E1 analogue) vag. 200 μg every 3 hours  Dinoprostone supp. (Pg E2) 20 mg every 3 hours  Dinoprostongel (Prepidil) 0.5 mg. 2. RU - 486 Mifepristone (Mifepristone) 150 – 200 – 600 mg p/o then in 24-48 hours +prostaglandins . 3. Extra – amniotic: Intermittent injection or continuous infusion:  Dinoprost (Pg E2α) 0.25 mg followed by 0.75 mg every hour  Diniprostone 0.05 mg followed by 0.2 mg every hour. Advantages for suction (best for early) Empties uterus rapidly • ↓ Blood loss < 2%, • ↓ risk for perforation of uterus < 1%. Complications for suction Ink – < 1% Mortality – 1/100:1000. Note: - D&C - other indications: • Dg of abnormal uterine bleeding, • Endometrial polyps. Adverse effect ↑ chance for Asherman syndrome LATE. Induce the labour. Medical – i/uterine Pg E2 / F2α i/uterine hypertonic urea Extrauterine Pg E2 / F2α Vaginal Pg D&E (13 – 18 wks)– dilate with laminaria or Pg E1 and evacuate with larger cannula. Paracervical blockage + i/v sedation. Complications – Hemorrhage (Atony / laceration), Perforation. Rarely infection. (Retention of tissue is uncommon) Intra amniotic (>14-16wks) – Amnio infusion: I. Hypertonic saline – 200 ml  Necrosis of Endometrium (10-20%) II. Urea (better) III. Glucose (CI – DU) IV. Natural Pg V. 1/2 + augment with oxytocin Amnio infusion is done : 1) via abd wall (w/ U.S control 2) transcervically 3) transvaginally

N:…Mortality of mother ↑ with GA. Laminaria can be used a few hrs b/f amniocentesis to ↓ risk of cervical injury. Complications of amnio infusion: Bleeding + Allergy  Fetal death release of endogen contract the uterus  expelled fetus. Wait for 48 hrs contraction is absent then induce contractions. C.S (crporal) or/ Hysterectomy and Hysterotomy  can be done at any stage of pregnancy, but ↑ risk for rupture in next pregnancy. It ↑ morbidity + mortality neither is as a 1ْ met. Indications: Failure to complete a midtrimester, abortion due to cervical steno sis or failure in management of other complicant. Transverse cut’s impossible: lower segment is not developed (develops one after 30 GW) + Istmus is 1 cm (12 cm labour). Complications: • retained placenta – 30-46% infection (prophylactic a/b) • cervical laceration • failure of labour (to expulse the products of concep.) Menstrual regulation – 4-6 wks: Aspiration of endometrium within 14 d after mensed menstrual cycle or within 42 d after beginning of last menstrual period by small cannula attached to low pressure suction eg:-syringe / suction – machine. No need for anesthesia / paracervical block. Complication - persistant pregnancy. Post abortion procedures: 1) product of conception examined to validate complete evacuation + Hydatiform mole. 2) Instruct to alert for danger sign - ↑ tْ , chills, muscle ache, tired, … pain, cramp, block ache, tender abdomen, prolonged or heavy bleed, foul vaginal discharge, delay >= 3 m in resuming periods. 3) HCG ↓ gradually so (+) after procedure in blood. (… after 14 d) Pre – abortion counseling 10-19% Late complications, > 16GW  ↑ mortality. Complications: - Immediate – during / 3hrs after procedure, - Early (within the following 28 d) -Late (a/f 28 d) Immediate + Early: 1. hemorrhage (↓ with suction + highest in saline) 2. cervical injury – use of LA instead of GA (Laminaria to ↓ cervical injury) ↑ in nulliporous …org cervix. 3. uterine perforation (Multiporty, Advanced GA, inexperienced operator ↑ risk – usage of laminaria ↓ risk. Serious consequences  hemorrhage + damage to intra abdominal organs. 4. Acute haematometra - ↓ vaginal bleeding, enlarged tender uterus, repeat curettage and administer oxytocic agents. 5. Anesthesia complications (Anaphylactic shock) 6. Amniotic …….. ---“--- - collapse, DIC, bleeding. Late: • infection – ascending ; Exogenous. • Bleeding. 3-6 d after retention, • Recurrent miscarriages
