Task: Answer Verification
Input (English): Question: Does thoracic epidural anesthesia with ropivacaine compromise the tolerance of acute normovolemic anemia in pigs?
Answer: Thoracic epidural anesthesia with ropivacaine 0.2% does not decrease the tolerance to acute normovolemic anemia in healthy pigs. The hemodynamic compensation of acute anemia is fully preserved despite sympathetic block, and the critical hemoglobin concentration remains unaffected.
Output (English): no
