Summary
This study proposes an anesthesia protocol for patients with Factor X deficiency, a rare bleeding disorder. Pre-anesthetic coagulation studies are crucial for managing surgical risks in these individuals.
Area of Science:
- Anesthesiology
- Hematology
- Coagulopathies
Background:
- Factor X deficiency is a rare inherited bleeding disorder with diverse clinical manifestations.
- Anesthesia management for patients with coagulopathies requires careful planning to mitigate bleeding risks.
- Surgical procedures in patients with rare factor deficiencies necessitate specialized protocols.
Observation:
- A 26-year-old female patient, classified as ASA II, with congenital Factor X deficiency was scheduled for ovarian neoplasm excision.
- Pre-anesthetic evaluation revealed prolonged Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT), and an elevated International Normalized Ratio (INR).
- Physical examination and other laboratory tests were within normal limits.
Findings:
- The patient's coagulation profile (PT 22.1s, INR 1.99, aPTT 41.4s) indicated a significant deficiency in Factor X activity.
- The case highlights the importance of thorough bleeding history assessment in patients with known or suspected coagulopathies.
- Standard laboratory coagulation tests are essential for identifying and quantifying factor deficiencies prior to anesthesia.
Implications:
- Development of specific anesthesia protocols for Factor X deficiency patients is critical for surgical safety.
- Pre-operative coagulation screening is vital for all patients, especially those with a history of bleeding or known coagulopathies.
- This case underscores the need for multidisciplinary collaboration between anesthesiologists and hematologists in managing rare bleeding disorders.
