⁴Çukurova Üniversitesi Tıp Fakültesi, Anestezi ve Reanimasyon Anabilim Dalı, Adana, Prof. Dr. Purpose: To compare bupivacaine-lidocaine mixture with levobupivacaine-lidocaine mixture in peribulbar block regarding their effect on quality of block, ocular akinesia, and degree of intraoperative pain and postoperative pain.
Materials and Methods: Sixty-two ASA physical status I-III patients scheduled for elective cataract surgery were included in the study. Patients were randomly allocated to receive peribulbar anesthesia with either 4 ml of a mixture levobupivacaine 0.5% and lidocaine 2% (Group LL) or a 4 ml of a mixture containing equal volume of lidocaine 2% and bupivacaine 0.5% (Group LB). All patients were evaluated with regards to akinesia and pain scores along the surgery pain and sedation scores postoperatively.
Results: Median eyelid movement and akinesia scores were not significantly different between the two groups at any time. There was no need for a supplemental block during surgery in any patient. Sedation scores were significantly higher in group LB than the LL group in study period.
Conclusion: Levobupivacaine plus lidocaine and bupivacaine plus lidocaine can be recommended as an effective analgesics in cataract surgery without serious side effects. However, higher sedation was achieved with combination of bupivacaine and lidocaine. Keywords : Peribulbar anesthesia, levobupivacaine, bupivacaine, phacoemusification, cataract
