Task: Answer Verification
Input (English): Question: Does the antero-posterior diameter of the lumbar dural sac predict sensory levels of spinal anesthesia for Cesarean delivery?
Answer: The lumbar DSD, as determined by ultrasound, is not a predictor of spinal anesthesia spread. Further research is necessary to understand if ultrasound findings can be used to predict intrathecal spread of local anesthetics.
Output (English): no
