Background: Intraoperative lidocaine is widely used in controlling discomfort during cataract surgery. However, recent studies have confirmed the toxic effect of lidocaine on ganglion cells. Ropivacaine is an anesthetic recently introduced in clinical practice that couples a long anesthetic effect with a mild vasoconstrictive action. Objective: The aim of this study was an in vitro evaluation of the efficacy of ropivacaine in reducing the degenerative effects usually observed during lidocaine treatment. Methods: Ropivacaine and lidocaine toxicity has been evaluated in murine fibroblasts 3T6 by measuring percentage of cell death, cell growth inhibition, and DNA degradation. The choice of this cellular line is motivated by the presence of a complete apoptotic system that can be assimilated to the endothelium precursor cells. Results: We observed that lidocaine 0.25% decreases cell viability and causes DNA degradation in murine fibroblasts 3T6, whereas ropivacaine 0.5% does not cause any cellular or molecular degenerative effect. Conclusions: Our in vitro studies confirm that ropivacaine is less toxic than lidocaine to these cells. Therefore, in vivo studies in the anterior chamber could be useful to evaluate the effects of ropivacaine versus lidocaine in intracameral anesthesia in cataract surgery. © 2011 Vergani & Rusconi, publisher and licensee Adis Data Information BV.

Abstract

Background: Intraoperative lidocaine is widely used in controlling discomfort during cataract surgery. However, recent studies have confirmed the toxic effect of lidocaine on ganglion cells. Ropivacaine is an anesthetic recently introduced in clinical practice that couples a long anesthetic effect with a mild vasoconstrictive action. Objective: The aim of this study was an in vitro evaluation of the efficacy of ropivacaine in reducing the degenerative effects usually observed during lidocaine treatment. Methods: Ropivacaine and lidocaine toxicity has been evaluated in murine fibroblasts 3T6 by measuring percentage of cell death, cell growth inhibition, and DNA degradation. The choice of this cellular line is motivated by the presence of a complete apoptotic system that can be assimilated to the endothelium precursor cells. Results: We observed that lidocaine 0.25% decreases cell viability and causes DNA degradation in murine fibroblasts 3T6, whereas ropivacaine 0.5% does not cause any cellular or molecular degenerative effect. Conclusions: Our in vitro studies confirm that ropivacaine is less toxic than lidocaine to these cells. Therefore, in vivo studies in the anterior chamber could be useful to evaluate the effects of ropivacaine versus lidocaine in intracameral anesthesia in cataract surgery. © 2011 Vergani & Rusconi, publisher and licensee Adis Data Information BV.
