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. The researchers want to investigate whether the use of fentanyl citrate by peribulbar route, when administered with a local anesthetic, shortens the anesthetic latency, interfere with the degree of akinesia and if provides greater postoperative analgesia.
