Complications of Abortion

Complications of Abortion - First Wave Woes

Immediate complications, often life-threatening:

• Hemorrhage:
  • Causes: Uterine atony, retained products of conception (RPOC), genital tract trauma (uterine perforation, cervical laceration).
  • May lead to hypovolemic shock. Blood loss >500ml is significant.
• Shock:
  • Types: Hypovolemic (most common due to hemorrhage), septic (delayed onset usually, but can be rapid with severe infection), neurogenic (vasovagal, e.g., from cervical manipulation).
• Uterine Perforation:
  • Risk factors: Retroverted uterus, previous C-section, inexperienced operator, procedure type (D&C > MVA).
  • Common sites: Fundus, anterior/posterior wall at level of internal os.
• Cervical Injury:
  • Lacerations from tenaculum, forceful dilatation.
  • Potential for immediate hemorrhage, future cervical incompetence.
• Anesthetic Complications:
  • Reactions to local or general anesthesia (e.g., allergy, toxicity, respiratory depression, aspiration).

⭐ Hemorrhage is the most frequent immediate complication of abortion procedures and a leading cause of maternal mortality associated with abortion globally when severe and unmanaged.

Complications of Abortion - Infection's Fury

• Delayed Complications:

  • Retained Products of Conception (RPOC): Common cause of persistent bleeding & nidus for infection. Modern diagnosis utilizes ultrasound with Doppler for vascularity assessment and hysteroscopy for both diagnosis and removal.
    • 
  • Infection: Progresses from endometritis to salpingitis, oophoritis, parametritis, peritonitis. Can lead to life-threatening septicemia and septic shock. Strict infection control and biosafety measures are essential during procedures.
  • Pelvic Inflammatory Disease (PID): Chronic sequelae include chronic pelvic pain, dyspareunia, ectopic pregnancy, and infertility. Recent epidemiological data shows increased long-term reproductive complications.
  • Asherman's Syndrome (Intrauterine Adhesions): Results from endometrial trauma, leading to amenorrhea, hypomenorrhea, recurrent pregnancy loss, or infertility.

• Septic Abortion:

  • Definition: Any abortion (spontaneous or induced) complicated by uterine infection and systemic signs.
  • Common Organisms: Polymicrobial; E. coli, Staphylococcus aureus, Group A & B Streptococcus, Bacteroides, Clostridium perfringens.
  • Clinical Features: Fever (variable presentation, may not always exceed 38°C, especially in immunocompromised patients), chills, tachycardia, hypotension, lower abdominal/pelvic pain, uterine tenderness, purulent/foul-smelling vaginal discharge.
  • Forensic Significance: Abortion is legal in India. WHO classifies abortion safety as 'safe,' 'less safe,' and 'least safe' rather than the previous dichotomous classification. Unsafe abortions remain a major cause of maternal deaths globally.

⭐ Clostridium perfringens infection (gas gangrene of uterus) is a dreaded complication, causing "Bronze Uterus" or "Uterus Aerogenes" (palpable crepitus over uterus/abdomen), with rapid progression to toxemia, massive intravascular hemolysis (port-wine urine), renal failure, and often death.

• Comprehensive Management of Septic Abortion:

Complications of Abortion - Lasting Scars & Law

• Systemic Complications (Severe):
  • Embolism (Air, Amniotic fluid).
  • Disseminated Intravascular Coagulation (DIC).
  • Acute Renal Failure (often post-sepsis/hemorrhage).
• Late Sequelae (Long-term):
  • ↑ Risk of ectopic pregnancy.
  • Secondary infertility (e.g., Pelvic Inflammatory Disease (PID), Asherman's syndrome).
  • Menstrual irregularities.
  • Rh isoimmunization (if anti-D prophylaxis missed in Rh-ve mother).
• Medico-legal Aspects (India):
  • Differentiating natural vs. induced abortion complications.
  • Signs of Unsafe Abortion:
    • Genital tract trauma (perforations, tears).
    • Foreign bodies, chemical irritants in genital tract.
    • Septic abortion with bacteremia and sepsis.
  • MTP Amendment Act, 2021 Violations: Non-compliance regarding authorized person, approved place, valid opinion, informed consent, or gestational limits (extended to 24 weeks for special categories).

⭐ A key medico-legal indicator of interference in an abortion case is the presence of specific injuries like cervical tears or uterine perforation not typically seen in spontaneous abortions, or the discovery of foreign objects/substances in the genital tract.

High‑Yield Points - ⚡ Biggest Takeaways

• Hemorrhage: Most common immediate complication; potentially life-threatening.
• Sepsis/Septic Abortion: High risk with unsafe abortions; may lead to endotoxic shock.
• Uterine Perforation: Instrumental injury; risk of bowel/bladder damage.
• Retained Products of Conception (RPOC): Causes persistent bleeding, subinvolution, and infection.
• Asherman's Syndrome: Significant late complication; leads to intrauterine adhesions, amenorrhea, infertility.
• Air Embolism: Rare, often fatal, especially with illegal abortions (outside MTP Act 2021 provisions).
