Task: Answer Verification
Input (English): Question: Does the number of injections influence local anesthetic absorption after paravertebral blockade?
Answer: The injection of a single large bolus of local anesthetics into the paravertebral space does not increase its absorption. Maximal ropivacaine plasma concentrations resulting from paravertebral blockade are similar to those reported with equivalent doses of bupivacaine.
Output (English): no
