Septic Abortion
On this page
Direct answer
Septic abortion is infection of the uterus and its contents surrounding an abortion, classically following an unsafe or illegally performed termination but also occurring after spontaneous miscarriage with retained products. It presents with fever of 38 degrees Celsius or more, lower abdominal and uterine tenderness, purulent or foul-smelling discharge and tachycardia, and it can progress within hours to septic shock, disseminated intravascular coagulation and acute kidney injury. Management is resuscitation, high-dose broad-spectrum intravenous antibiotics started immediately, and evacuation of the uterus once the woman is stabilised — a sequence that once made septic abortion a leading cause of maternal death in India before liberal abortion law.
What you must remember
- Diagnosis: abortion plus fever of at least 38 degrees Celsius, uterine or adnexal tenderness, foul-smelling discharge, tachycardia and tachypnoea; look for cervical or uterine injury, retained products and the entry point of infection.
- Typical organisms: Escherichia coli and other gram-negative bacilli, anaerobes such as Bacteroides and Peptostreptococcus, group A streptococcus, Staphylococcus aureus and Clostridium perfringens — clostridial infection signals gas gangrene with haemolysis, subcutaneous crepitus and rapidly progressive shock.
- Antibiotics: start immediately after blood cultures — a classic regimen is clindamycin plus gentamicin with metronidazole, or broad beta-lactam combinations such as piperacillin-tazobactam or a carbapenem in severe sepsis; add antitoxin-supportive critical care for clostridial cases.
- Evacuation: suction or instrumental evacuation after haemodynamic stabilisation removes the infected nidus; delaying surgery while the woman deteriorates is a recognised error.
- Complications: septic shock, disseminated intravascular coagulation, acute kidney injury from hypotension and haemolysis, peritonitis, pelvic abscess, uterine perforation and injury to bowel or bladder; hysterectomy is reserved for uncontrolled sepsis, gangrenous uterus or major uterine injury.
- Supportive care: oxygen, aggressive fluid resuscitation with vasopressors as needed, blood and blood product correction of coagulopathy, monitoring of urine output (target at least 0.5 ml/kg/hour) and intensive nursing.
- Legal context: the Medical Termination of Pregnancy Act 1971, amended in 2021, permits termination up to 20 weeks (24 weeks for certain categories) through registered providers — unsafe clandestine procedures remain the source of most septic abortions.
Common confusion
The sequence is what examiners test: antibiotics come first and immediately, with evacuation after stabilisation — not the reverse, and never antibiotics alone hoping the fever settles. A second trap is underestimating the quiet clostridial case: fever with haemoglobinuria, jaundice or a rapidly enlarging tender uterus means gas gangrene, not simple endometritis, and demands urgent surgical review rather than another day of conservative care.
Exam-focused takeaway
Stems describe a woman days after an unregistered termination with fever and a tender uterus, asking either the causative organism, the antibiotic regimen or the next step — the answer being immediate broad-spectrum intravenous antibiotics followed by evacuation. Complication-based questions cover disseminated intravascular coagulation and acute kidney injury management, and one-liners address the MTP Act limits. Clostridium perfringens with haemolysis is the classic image-based or laboratory-based hook.
Frequently asked questions
What defines septic abortion?
An abortion complicated by infection, diagnosed by fever of at least 38 degrees Celsius with uterine tenderness and foul-smelling discharge, most often after an unsafe termination.
Which organisms are commonly responsible?
Gram-negative bacilli such as Escherichia coli, anaerobes including Bacteroides, streptococci, staphylococci and Clostridium perfringens.
What is the correct management sequence?
Resuscitate and start broad-spectrum intravenous antibiotics immediately after cultures, then evacuate the uterus once stable, with critical-care support for shock.
When is hysterectomy required?
For uncontrolled sepsis, a gangrenous or extensively injured uterus, unrepairable perforation or ongoing haemorrhage despite conservative surgery.
What does the MTP Act permit?
Termination up to 20 weeks (24 for defined categories after the 2021 amendment) by registered practitioners, making safe abortion accessible and septic abortion largely preventable.
