Balancing Anticoagulation and Neuraxial Procedures in the Peripartum Period: An Update

Area of Science:

• Obstetrics and Gynecology
• Anesthesiology
• Hematology

Background:

• Thrombotic pulmonary and venous embolism is a significant cause of maternal mortality in the US.
• Expanded venous thromboembolism prophylaxis guidelines have been issued by major medical organizations.
• Increased pharmacologic thromboprophylaxis, especially with heparins, poses challenges for anesthesia decisions.

Purpose of the Study:

• To review the complexities of anesthesia management in pregnant patients receiving thromboprophylaxis.
• To highlight the risks associated with neuraxial and general anesthesia in this population.
• To emphasize the importance of individualized risk assessment for obstetric patients.

Main Methods:

• Review of current guidelines and recommendations from professional organizations.
• Analysis of the risks and benefits of different anesthetic techniques in the context of anticoagulation.
• Discussion of strategies for managing patients requiring thromboprophylaxis and anesthesia.

Main Results:

• Neuraxial anesthesia is complicated by the risk of spinal epidural hematoma with heparin use.
• General anesthesia presents higher maternal risks compared to other anesthetic options.
• Individualized risk assessment is crucial for selecting the safest anesthetic approach.

Conclusions:

• Careful consideration of thromboprophylaxis and anesthesia is essential to minimize maternal mortality.
• Collaboration between obstetricians, anesthesiologists, and hematologists is key.
• Personalized risk-benefit analysis guides the optimal management of anesthesia in pregnant patients on anticoagulation.
