• Important cause of maternal morbidity and mortality

• Ectopic pregnancy
• Gestational trophoblastic disease
• Implantation bleeding

Gynaecological complications
• Cervical cancer• Infections• Cervical polyp

The normal pregnancy
Symptomatology • Classical trial• Amenorrhoea• Pelvic or low abdominal pain• Vaginal bleeding

First test is to demonstrate the presence of HCG - HCG
• Glycoprotein
• 2 subunits
• Half life 6 to 24 hours
• Peak level at 9 to 13 weeks
![Page 7: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/7.jpg)
Urine test
• Sensitivity is around 25 IU/Ltr
• Positive results around 14 days after ovulation
Plasma HCG
• 0.1 to 0.3 iu/L is able to detect a pregnancy 6 to 7 days after ovulation

Different types of abortion
1.Threaten abortion is characterised by• Bleeding aft amenorrhoea• No uterine contraction and pain• The cervix is closed• Uterus size is similar to date
![Page 12: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/12.jpg)
2.Inevitable abortion• There will be – more bleeding• Uterine contraction and pain• The cervix is dilated
![Page 13: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/13.jpg)
3. Complete abortion• The whole conceptus is expelled• Uterus contracts to normal size• Bleeding stops• The cervix is closed
![Page 14: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/14.jpg)
4. Incomplete abortion• There will be products of conception• Bleeding continue and severe
accompanied by shock• There will be pain• Infection may supervene
![Page 15: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/15.jpg)
5. Missed abortion• Dead fetus retained in the uterus• Size of uterus is smaller than dates• Signs + symptoms of pregnancy reduced• Brownish discharges per vaginum• The os is closed• In ultrasound there is no fetal heart
movement
![Page 16: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/16.jpg)
6. Septic abortion• Caused by incomplete abortion
complicated by infection• There will be pyrexia• Abdominal pain + pelvic tenderness• Foul smelling purulent discharge per vagina
![Page 17: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/17.jpg)
7. Habitual abortion• Three or more consecutive abortion
(spontaneous)
![Page 18: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/18.jpg)
Management of different types of abortion
• Threatened abortion• Reassurance• Bed rest• Sedation• Uterine relaxants• Hormone (progestogen)• USS to check viability• All pads + everything passed may be saved
for examination• Modern approach – no treatment has
proved the value
![Page 19: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/19.jpg)
Management of different types of abortion
• Inevitable abortion• Incomplete abortion• Missed abortion• Complete abortion
– No treatment required– Habitual abortion
• Treat the cause if cause is found• Treat general disease if present
![Page 20: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/20.jpg)
Management of septic abortion
• General• Nursing care• Nutrition• Fluid and electrolytes balance• Correct anaemia• To note urine out put
![Page 21: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/21.jpg)
Specific• Cervical swab• High vaginal swab for C & S• Blood culture• IV Antibiotics• C Pen & ampicillin – gm(+)• Gentamycin – gm (-)• Metronidazole – anaerobes• Antitetanus toxoid• Remove the septic focus
![Page 22: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/22.jpg)
• Management of septic abortion• Evacuation and curettage for RPOC• POD puncture and drainage• Laparotomy and drainage• TAH if perforation detected
![Page 23: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/23.jpg)
Septicaemic shockSepticaemic shock• Keep is ICU
• O2
• Correct acidosis• Blood transfusion if require• Antibiotics intravenously• Blood and heparin for DIC
![Page 24: Abortion prof druw-pe](https://reader036.fdocuments.us/reader036/viewer/2022062307/554b4610b4c905cd2c8b50b0/html5/thumbnails/24.jpg)
Renal failureRenal failure (Urine output < 30 ml/hr) increased urea and electrolytes
• Restrict fluid• High carbohydrate, low protein• Restriction of sodium and potassium• Dialysis if blood urea more than 25 mmol/l• Manitol• frusemide
