Which factor must be evaluated before regional anesthesia to minimize risk?

• A. Favorite food
• B. Hair color
• C. Coagulation status
• D. SAT score

Answer: (C)

Evaluating bleeding risk is essential before performing regional anesthesia. Regional techniques, such as spinal, epidural, or peripheral nerve blocks, can lead to bleeding into closed spaces. A hematoma in these areas, especially around the spinal cord or nerve plexuses, can cause serious nerve compression or neurological injury. Therefore, assessing coagulation status helps identify patients at higher risk and guides safe timing and management—checking platelet count and coagulation tests (PT/INR, aPTT) and reviewing any anticoagulant or antiplatelet medications. If coagulation is abnormal or anticoagulation cannot be safely paused, the block may be delayed or alternative anesthesia considered. Other factors like favorite food, hair color, or SAT score do not affect the safety of regional anesthesia and are not relevant to minimizing risk.
