Background: Cataract surgery is the most frequent operation performed in Ophthalmology, and the subtenon block is one
of the executed modalities of regional anesthesia. This study aims to compare the quality of anesthesia between ropivacaine
and racemic bupivacaine in the subtenon block for cataract surgeries with phacoemulsification technique.
Methods: Clinical trial, randomized and double-masked, comparing the quality of anesthesia of 1% ropivacaine (GR) and
0.75% racemic bupivacaine with epinephrine (GB) under subtenon block for cataract surgery. Sample with 64 patients,
32 randomly assigned to GR and 32 in GB. All blockages were performed with 5 mL solution added with 40 IU/mL
hyalurunidase. Motor akinesia, intraocular pressure, ocular perfusion pressure, analgesia, sedation level and anthropometric characteristics were eval.. View more»
