LETTER TO THE EDITOR
Cant Blame Ropivacaine

To the Editor:
James and Panni (1) described a case of an unusual prolonged unilateral spinal anesthesia (20 h) using isobaric ropivacaine. Previously, an exceptionally prolonged anesthesia (36 h) after spinal anesthesia has been reported, but the local anesthetic was an hyperbaric bupivacaine (2). Interestingly, in both cases, fentanyl was added to the local anesthetic. In James and Pannis case, since a vasoconstrictor was not used and the addition of fentanyl to intensify and prolong ropivacaine block did achieve its intended purpose, as well as because of a lack of evidence to single out ropivacaine as the sole culprit for the protracted anesthesia, ropivacaine cannot be blamed alone. Also, the title would be better read as "Extremely Prolonged Unilateral Block with Spinal Ropivacaine plus Fentanyl (20 hours) Used for Cervical Cerclage."
