[Peribulbar anesthesia: comparing 1% ropivacaine and a mixture of 0.5% bupivacaine--2% lidocaine].
OBJECTIVE
To compare the efficacy of 1% ropivacaine with a mixture of 0.5% bupivacaine and 2% lidocaine in peribulbar anesthesia for elective cataract surgery.


METHODS
Prospective double-blinded study, enrolling 100 patients randomly assigned to two different groups. Group 1 received 9 ml of 1% ropivacaine and group 2 received 4.5 ml of 0.5% bupivacaine and 4.5 ml of 2% lidocaine. Both groups received 1 ml of hyaluronidase to reach a total volume of 10 ml.


CONCLUSIONS
No difference between the groups was noted during the study regarding not only onset time, but also the duration of anesthesia and perioperative analgesia. A greater incidence of pain on injection was significantly reported in group 2 (p<0.001). Patients in group 1 had less need for top-up injection and showed better ocular akinesia (p<0.01).
