In the daily practice of ophthalmologic surgery, locoregional anesthesia is predominantly used for cataract surgery. The use of retrobulbar lidocaine was first described in 1885 by Herman Knapp [1] to perform the enucleation of a patient wounded in war; is not until the mid-1950 [2] when retrobulbar block is popularized. AbstractIntroduction: Ophthalmological procedures such as cataract extraction can be carried out with a Peribulbar Block (PBB). The advantages of this anesthetic technique include a lower incidence of coughing, unwanted movements and emesis during awakening, in addition to providing adequate postoperative analgesia.We observed that the use of fentanyl citrate by peribulbar route, when administered with a local anesthetic, shortens the anesthetic latency, does not interfere with the degree of akinesia and provides greater postoperative analgesia. The combined use of local anesthetics and fentanyl citrate in ophthalmic surgery offers great benefits for the patient, also allowing the surgeon an adequate surgical field. We observed in ophthalmic surgery with regional anesthesia that the peribulbar use of fentanyl citrate is an alternative that provides a greater intraoperative and postoperative analgesia when combined with local anesthetics.Objective: Demonstrate that the lidocaine-bupivacaine-fentanyl combination is better than the lidocaine-bupivacaine combination, since the former shortens the latency time of Peribulbar Block (PBB), produces the same degree of akinesia of the eyeball and provides longer postoperative analgesia time. Conclusion:The use of fentanyl citrate peribulbar shortens the latency time, does not interfere with the degree of ocular akinesia and provides better postoperative analgesia, so this combination of anesthetics may be a good alternative for cataract ophthalmic surgery under regional anesthesia.
