^*Local anesthetic (0.25% bupivacaine) volume used in blocks per side as single injection. This table is for informational purposes only based on authors’ clinical practice. For the use of other local anesthetics, such as lidocaine and ropivacaine, it is recommended to consult the literature. About 4-8 mg dexamethasone and/or 1:200 000 epinephrine could be added as an adjuvant drug.
