Ultrasound-Guided Peribulbar Block with Blunt Canula for Cataract Surgery: A Review of Historical Case-Series

Introduction: Cataract surgery is one of the procedures most performed worldwide. Those are several options for anesthetic management, with many factors that affect choice any given technique, depending on patients’ needs, surgeons’ preferences and institutional facilities processes. Although being more invasive than topic anesthesia, possible hazardous side effects, peribulbar block still an effective successful technique. The utilization blunt canula ultrasound guidance might enhance safety pattern this Methods: This article presents a revision 1089 consecutive cases from February 2016 to January 2022, patients submitted cataract under anesthesia guidance. Results: 1318 surgical records were selected, filling inclusion criteria. There was higher prevalence feminine gender (54%), median age 64.3 (28 - 102) years. Mean IAV 2.9 mL (sd 0.16 mL, 2.5 3.0 mL), total HOS 91.1%; OR reach G2 or above each (ISB/IMB) 11.0; CA 47.9%, mean FAV 4.29 2.17mL, 15 mL). In 8.9% patients, could not be fully observed. ISB, IMB, calculated both groups (non-HOS HOS-only). (non-HOS/HOS-only) 126.21. main adverse effects chemosis (2.9%), hyposphagma (5.7%) high IOP (7.5%). No procedure postponed due anesthesia-associated events. Discussion: study points towards feasibility described technique in outpatient fashion, low, mild tolerable associated.
