Anaesthesia Considerations for Haemophilia During LSCS

For patients with haemophilia undergoing LSCS, neuraxial anaesthesia can be safely performed if factor levels are adequately corrected: maintain Factor VIII/IX ≥50 IU/dL for mild bleeding history or ≥80 IU/dL for severe bleeding history before spinal or epidural placement. 1

Key Decision Algorithm

Pre-procedure Factor Level Requirements

For patients with haemophilia A or B:

  • Mild bleeding history: Factor VIII/IX ≥50 IU/dL acceptable for spinal anaesthesia or epidural insertion/removal 1
  • Severe bleeding history: Factor VIII/IX ≥80 IU/dL required for neuraxial techniques 1
  • Symptomatic carriers with normal baseline levels: Case-by-case evaluation with multidisciplinary team required 1

These recommendations represent the most current 2025 ISTH consensus guidelines, which provide more nuanced guidance than the 2020 World Federation of Hemophilia guidelines that formally recommended against neuraxial anaesthesia in haemophilia patients 1.

Defining Bleeding History Severity

Mild bleeding: Never required blood transfusion or haemostatic surgical intervention (suturing, cautery, reoperation) 1

Severe bleeding: Required blood transfusion or haemostatic surgical intervention 1

Intraoperative Management

Factor Replacement Strategy

  • Target factor levels: Maintain ≥80-100% of normal for major surgery (LSCS qualifies as major surgery) 2
  • Haemophilia A: Use recombinant or plasma-derived Factor VIII concentrates
  • Haemophilia B: Use recombinant Factor IX concentrates, maintain 60-80% or higher 2

Adjunctive Haemostatic Therapy

  • Tranexamic acid: Strongly recommended as adjunct, particularly beneficial for procedures with high fibrinolytic activity 2
  • DDAVP: Consider for mild-moderate haemophilia A (increases Factor VIII 2-3 fold); ineffective in severe haemophilia A or any haemophilia B 2

Monitoring Parameters

If bleeding concerns arise intraoperatively:

  • aPTT: Will be prolonged with low factor levels (though not reliably predictive)
  • Haemoglobin/haematocrit
  • Fibrinogen levels
  • Platelet count 2

Anaesthetic Technique Selection

Neuraxial Anaesthesia (Preferred if Factor Levels Adequate)

Advantages for LSCS:

  • Superior pain control
  • Reduced bleeding risk compared to general anaesthesia
  • Mother awake for delivery
  • Avoids airway manipulation

Absolute requirements:

  • Documented factor levels meeting thresholds above
  • No concurrent platelet dysfunction or thrombocytopenia
  • Factor replacement given with adequate time to achieve target levels

General Anaesthesia (Alternative)

Indications:

  • Inadequate factor levels despite replacement
  • Urgent/emergent delivery without time for factor correction
  • Patient refusal of neuraxial
  • Concurrent coagulopathy 3, 4

Technique considerations:

  • Avoid NSAIDs for postoperative analgesia 3
  • Use IV patient-controlled analgesia (remifentanil or morphine) 3
  • Prepare for potential uterine atony with multiple uterotonics available 3

Critical Pitfalls to Avoid

  1. Do not assume normal factor levels in carriers: Female haemophilia carriers can have significant bleeding despite "normal" factor levels; symptomatic carriers require individualized assessment 1

  2. Do not perform neuraxial without documented factor levels: Clinical history alone is insufficient; laboratory confirmation is mandatory 1

  3. Do not use aPTT as sole guide: While prolonged aPTT suggests low factor levels, it is not reliably predictive of bleeding risk 2

  4. Timing of factor replacement: Ensure adequate time between factor administration and neuraxial procedure for peak effect

  5. Epidural catheter removal: Same factor level thresholds apply for catheter removal as for insertion 1

Special Considerations for LSCS

Uterine Atony Risk

  • Haemophilia patients may have increased bleeding from uterine atony 3
  • Have multiple uterotonic agents immediately available (oxytocin, carboprost, misoprostol, carbetocin)
  • Consider tranexamic acid prophylactically

Blood Product Availability

  • Ensure cross-matched blood products available
  • Fresh frozen plasma may be needed if factor concentrates unavailable 3, 4
  • In resource-limited settings, FFP 10 mL/kg can be used for factor replacement 4

Postoperative Management

  • Continue factor replacement to maintain levels >50 IU/dL for 3-5 days postoperatively
  • Monitor for delayed bleeding
  • Some protocols recommend prophylactic FFP on postoperative day 3 4

Preoperative Preparation Checklist

✓ Confirm haemophilia type (A vs B) and severity ✓ Document baseline factor levels ✓ Classify bleeding history (mild vs severe) ✓ Arrange factor concentrate availability ✓ Coordinate with haematology for dosing recommendations ✓ Ensure blood products cross-matched and available ✓ Plan anaesthetic technique based on corrected factor levels ✓ Prepare alternative anaesthetic plan if factor correction inadequate
