摘要

We thank Dr. M. del-Rio-Vellosillo et al. [1] for addressing our article [2].We wish to respond to their questions.In our study, intravascular (iv) solutions and injection rates were the same in both groups. We did not administer special iv pre-loading. Intrathecal injections were carried out for 20 s without barbotage or aspiration.The methods used by our group and by del-Rio-Vellosillo et al. were different as it relates to the dose of local anesthetic and patient position. The most important methodological difference affecting the level of anesthesia and the block duration times between the two studies is the dose of local anesthetic. In our study, 15 mg of bupiva-caine or levobupivacaine was administered and, in their study, 12.5 mg was administered.
