Summary
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.
